The traverser traversed himself

There is no need to meet that enthusiastic aunt... Anyway, Zheng Yichen noticed that the other party looked at her a little strangely in the past two days.

"Based on the current weight, this is the last time, actually." Zheng Yichen sensed the bottles filled with metal powder stuffed in the shadow space, and couldn't help but sigh: "There is still a long way to go in the future. .”

"Then work hard." Dinisha said. She knew that Zheng Yichen had to pay something for bringing her here. What he paid was definitely not something that could be obtained casually... Well, anyway, after summoning Dinisha these days This time, the head price of two reincarnations has been used up.

Things like kill reward points will also increase as the enemy's strength increases in the future, but as it increases, the difficulty will also increase.

"let's start."

"Wait a minute, take this with you first." A bag came out from the shadow at Zheng Yichen's feet. The thing inside was a tights. The thing that was once promised to Lucila would be given to her if there was a chance. ...The price for getting this thing is that the list given by the wind chime has several new requirements.

Anyway, after Zheng Yichen's promise, the number of things in the list given by the two of them suddenly increased several times. Things that once could be obtained with hundreds or even thousands of trading reward points are now out of the question without thousands. Gotta take it down!

Their research has just started and requires too many resources, especially things that they could not get at all in the past. After all, the better and more extensive the resources, the higher the research breakthrough is likely to be, and the things he currently holds in the shadow space are also Quite a few, a scorching blade, a small cannon, two large swords... These two were brought over by Dinisha for spare use.

Zheng Yichen did ask if there were any raw materials for making great swords over there, but the weapons and equipment that she found from some of the organization's warehouses did not have so-called raw materials, but only some research drugs and equipment, and the rest It's just these white swords that are shaped and have no sword seals engraved on them.

The quantity is too much for them to use up.

This made Zheng Yichen think a lot. The material of this kind of big sword is very hard. To turn it into powder requires violent disassembly. There is not much technical content. As long as the destructive power is enough, fine work is impossible, otherwise it will be made with Use the raw materials of the great sword to make a set of equipment...

Forget it if you use it yourself. After the demon awakens, if there is a set of iron knots covering his body, the sword blades on his body will not be able to pop out.

Even under normal circumstances, it is difficult for Zheng Yichen to pop out the sword due to the down jacket and tights. This is why he rarely uses this method in battle. On the one hand, it is consumption, and on the other hand, it is destruction. Clothes.

"What else are you missing over there?"

"After the food problem is gone, there won't be much of a problem there. What's left is steady development... At least in this era, no one will be able to invade there." Dinisha said, doing the demonic synchronization every day At that time, she also heard a lot about the weapons that Zheng Yichen talked about that appeared with the development of the times.

For example, things like thermal weapons, even if such things appear, it will be a long time later. By then, it is not certain whether they will still exist or not. There is no need to worry now. Only Dinisha knows about this matter.

After the demonic synchronization ended this time, the metal powder on Zheng Yichen's arm was completely assimilated without any strange feeling. Zheng Yichen moved his arm slightly. The skin of his left arm did not change much, but it looked like it had A slightly strange feeling of stiffness.

Zheng Yichen stretched out his hand and touched it. It was like touching a titanium alloy plate. It was extremely hard, but it did not affect his activities at all. When he moved his fingers to stretch the muscles, he could see the changes in the skin. It was quite magical. However, the weight is not enough, so it can only be covered on the surface, or the transformed cells can be gathered into the fist area.

Zheng Yichen could clearly feel that when those cells gathered in the fist part, the normal cells were squeezed to another place. This change was very rapid. Zheng Yichen also had experience in using it, just as in the normal awakening state of a demon. Just control the way the body can extend the blade.

The next day, Feng Lin got the good news from Zheng Yichen early in the morning. She even made a much richer breakfast. Feng Ling also put down the experiment at hand and came here to watch.

"..." Feng Lin looked at a blunted scalpel in her hand. This knife was used to test the strength of Zheng Yichen's skin after it was alienated. However, after the alienation of the skin on Zheng Yichen's left arm, the color was not that big. Change, but the structure of the cells has completely changed. It is just a flesh-colored metal lump, so this sharp scalpel will be completely destroyed with this cut.

Even cutting meat is still powerful, but it no longer has the original sharpness.

"Sister, come on." Feng Lin silently gave up her position and let Feng Ling come up. Feng Ling did not move directly, but put her hands on Zheng Yichen's arms and groped for a while: "The texture is the same as that big sword. But the touch feels more like human skin, and the camouflage is perfect.”

After that, he took out the prepared small instrument and tested it on Zheng Yichen. The expression on the wind chime gradually became more subtle, as if he had discovered a new world: "It's amazing! It clearly possesses the properties of metal, but what it embodies is what living organisms should have." Information, it is absolutely impossible for a normal metal detector to detect abnormalities in your arm!"

After the metals in Zheng Yichen's arms were assimilated, they were no longer complete metals.

"Sister, I am responsible for this. You have crossed the line." Feng Lin looked at Feng Ling's excited look and said from the side. Her sister's extra study of 'biology' during this period was a bit excessive.

"I can try it first... Well, okay, let's test the hardness next." Feng Chime returned to his workbench and took out the potion prepared in advance... It is also a potion, and the effect is the same as Feng Lin's. Feng Lin's is used for medicinal purposes, but hers is used directly on materials.

The medicine in your hand is like this. Inject it into the cutting pen, and with a few strokes on the marked material, you can 'cut' it into the parts you need.

This is a chemical agent that is extremely destructive to metal objects, but does not do much harm to other things. The isolation method is also very simple. A special coating can make the metal ignore the destructive force of this agent.

It's just that after this medicine was dropped on Zheng Yichen's arm, it slid down naturally, without any abnormality...

"I'm stupid..." Feng Chime was stunned for a moment, and then shook his head vigorously: "Let's test it with physics."

The wind chime pulled Zheng Yichen and led him to a pressure testing machine. Zheng Yichen was stunned when he saw this thing. It looked familiar to him. Isn't this thing just a hydraulic press? ?

Before traveling through time, he had seen videos of hydraulic machines hitting various things. In these various hard fights, those who had a head-on confrontation with the hydraulic machine died, but those who used softness to overcome toughness survived. At the same time, he said that he had never seen videos of hydraulic machines hitting human hands.

Will you be the first to eat crabs after traveling through time?

"Then what? The alienation on my arm is just a layer of skin. If this thing is pressed down directly, the contents inside will not be squeezed out, right?"

"How can you squeeze out such strong skin?"

"I'm worried about the things in my arms getting squeezed in."

"It's okay, I will pay attention and stop when it reaches the limit." Feng Chime said while taking out the test tools that needed to be prepared, such as the awl and drill bit that can be installed on the 'hydraulic press'.

After an extremely violent test, Zheng Yichen gained an intuitive understanding of how hard the surface of his skin was. After the test, countless sparks flew up, and there were only a few more white marks on his arms, involving As for the parts that were directly cut or punctured, the impact was basically ignored. Only the strong pressure caused greater damage to Zheng Yichen.

Once the entire arm can be transformed, there will be no such drawbacks. The Kirin Arm is just around the corner!

Chapter 567 Back to School

"In terms of strength, it has been reduced due to the assimilation of biological characteristics. It is about 85% to 90% of the original range. Although the [-]% performance difference is not small, it will not affect its own strength. It's acceptable under the premise, but the main question now is...how do we extract cells with mutated cells?"

Feng Lin and Feng Lin frowned slightly and thought. This kind of thinking gave Zheng Yichen the subtle illusion that a group of top students were discussing whether a drop of water falling from a very high place would kill someone.

Maybe they had already thought of more than ten plans while they were frowning, but... who has never been caught in the rain...

"Do you still need to think about this? Can't you just scrape off a layer of skin?"

"...Scrape quickly!" X2.

It’s just a layer of skin. It’s not too easy for Zheng Yichen. Considering that he also needs to use it, the skin scraped off is not much, only less than one square centimeter. There is no change in the skin after scraping off. , the quality and strength still maintained the original effect. Feng Lin later gave Zheng Yichen two more bottles of active medicine.

A bottle of active potion can allow Zheng Yichen to assimilate one-tenth of the amount of metal powder he previously assimilated. If this amount is reduced by a large part from the original amount, the assimilation effect will be better, and the assimilation can even be completed in a short time.

However, this method is not unlimited. They do not have enough resources here. Even if a bottle of active potion can speed up Zheng Yichen's assimilation of a small bottle of metal powder, according to the schedule, it will take about ninety times for Zheng Yichen to use up all the It is difficult to complete two-thirds of the transaction reward points or even the kill reward points, and the materials required for the material formula of the active potion are extremely expensive.

This is because the reincarnation space is special. If you buy it with money in this world, it is destined to be an extremely difficult budget to apply for. You must know that some things are so rare that they cannot be bought with money. About ninety bottles of active medicine , even if some forces empty their inventories, it will be difficult to come up with so much material in a short period of time.

Fortunately, there is a reincarnation space behind Zheng Yichen, and there is no shortage of inventory... If such a situation occurs in the reincarnation space, then you can probably think about whether this reincarnation space is fake.

Two bottles of active medicine are enough for Zheng Yichen to replace the part of the mutated cells that was cut off before. As for the consumption of covering genes, the consumption ratio is not high. Even if it is not replenished, it can be maintained for a long time. Even if it is used up in the future, there will be no No matter how big the problem is, just one more injection will be enough.

Not to mention that on the basis of the alienated cells, the efficiency of assimilating metal powder has been greatly improved compared to before. An alternative way to describe it is that this thing can be regarded as a steel brace. It is more effective to grind bone powder with this thing. close.

Zheng Yichen kept one of these two bottles of active potion. He had already felt the benefits of this thing. According to the overall effect, it was far superior to the C-level life potion. Zheng Yichen suspected that this was better than the so-called B-level life potion. , the effect will not be bad...provided it is given time to take effect.

The remaining bottle of Zheng Yichen is used to replenish the consumption of a small piece of skin scraped off previously. Feng Lin has already calculated the amount. Zheng Yichen will not put more... Even if there is an extra part, the remaining few days will It can also be assimilated.

As long as the overall number is not too large.

Just as Zheng Yichen was slowly eating up the iron and Feng Lin and Feng Chime's research had made new progress, he was approached.

"Huh? Didn't you say you won't be back until the end of the month?" Zheng Yichen asked, looking at the girl in front of him in surprise.

"It was originally the end of the month, but the problem was solved early, so I came back early." Qi Mengmeng grabbed Zheng Yichen's wrist and pointed outwards...?Didn't move?

Qi Mengmeng, who was about to pull him away, looked at Zheng Yichen in surprise. She let go of her hand holding his wrist and stared at him for a while: "Your strength has increased again. How long has it been since?"

"Well, it doesn't take long."

"Is one or two months still a long time? We'll talk about things on the road. By the way, you didn't go out today, did you?"

Zheng Yichen shook his head. Qi Mengmeng did not drag Zheng Yichen this time. Just as he was about to say something, he saw Feng Lin and Feng Ling walking out together. When he saw the two of them, Qi Mengmeng's expression became even more strange. Feng Lin She knew that the reason for living here was to better observe this only qualified person.

She has already tried the weakened version of the limit-breaking training method. It feels like she really suffered, and she can also see some of her own shortcomings. Only with experience can she understand more clearly how difficult it is to use the real limit-breaking training method. Just what does wind chime mean here?

"Let's go together, we have to go back to school today." Feng Lin said proactively: "I also want to know what happened on the edge battlefield, which will delay you for more than half a month."

Although some things need to be kept secret, there are also some things that don't need to be kept secret, such as this encounter.

"Edge creatures can actually disguise themselves?" Feng Lin thought for a while after hearing this. Although edge creatures are also intelligent creatures, they are still somewhat different from humans. It is not easy for them to disguise themselves as humans, but now they have appeared. Feng Lin was not surprised at this situation. Some of the quite mature genetic medicine technology on the human side was 'learned' from marginal creatures.

At first, there was some controversy about genetic medicines. Is this stuff deliberately released by fringe creatures to deceive people? But in the end, humans themselves sorted out a unique system and it became a recognized technology. .

"How good is the disguise?"

"It's quite high, but they can disguise themselves as human beings, but they can't disguise the mental fluctuations of humans. Based on this, the marginal creatures disguised in the marginal battlefield have been uncovered, otherwise we wouldn't be able to come back so early. "

"The technology of marginal creatures is also improving." Feng Lin said. Their technological progress is currently aimed at humans, and various methods are available. Fortunately, humans are not bad at it, and there are threats to the survival of the race. existence, the energy that bursts out when they unite is quite large. Of course, they can persist from being weak at the beginning to being evenly matched now. The main reason is that the fringe creatures as invaders did not have the power to crush humans in this world in the first place.

Otherwise, everything would have been GG at the beginning, let alone how it could develop like this now.

"This is a trouble after all." Feng Chime said from the side. The edge battlefield can block the disguised edge creatures for a while, but it cannot be blocked forever. There are always some fish that slip through the net. Those pretenders ran into human society and wanted to find out. It’s very difficult. We can’t conduct physical examinations on everyone every once in a while, right?Even a physical examination cannot detect all of them.

"There will probably be a research course on related events after I return this time," Feng Lin said.

"Are you planning to participate?" Qi Mengmeng asked. The relevant courses... are nothing more than a simple and effective research direction. Just like the many viral methods used to deal with border creatures, the methods humans use to deal with them are very simple. , making various vaccinations, although it does not seem very novel, this method is extremely effective, because vaccines, the invisible means of harming marginalized organisms, have not been successful until now.

"It depends on the time. If it's not enough, I can write a paper instead." Feng Lin thought for a while and shook her head slightly. She had more important things to do in her hands. The small piece of paper she scraped off Zheng Yichen's finger The alienated skin brought new breakthroughs to her research.

Not for the use of that kind of cells, but for the research on covering genes. Through that piece of skin, she discovered many places that her previous research had ignored, which could ensure the smooth progress of her research. At the same time, the research on that piece of skin was important for The wind chime is also of great help. Using that piece of skin as a material, additional culture can produce a kind of degraded and alienated cells.

Because it is an additional culture, more other materials are added to the cultured materials, so that the newly cultured alienated cells have broken away from the original structure and become more metal-like. However, the difference is that the 'metal' is still the same. It is activated.

There are differences in the weight of activated metals cultivated by relying on different materials. However, this kind of research is still in its initial stage and cannot be directly matched with humans. It has not yet escaped from a limitation. After Zheng Yichen provides alienated cells, etc. Once some of the cells are exhausted, culture cannot continue.

As for the activated metal obtained by assimilating metal with the flesh and blood of the awakened, although it can also be used, the stability of that thing is too poor, and its use on humans will cause various unclear mutations.

Feng Lin has already set a goal. When she graduates, she must research the gene-covering medicine with mature results as her debut work after graduation. As for her sister's research, it is very synchronized with hers. Whoever gets the breakthrough first will be able to gain corresponding inspiration from each other.

The most tiring thing is not Feng Lin but her sister. After all, a new research path gives Feng Ling too much to learn. Thanks to her solid foundation, even if she learns other knowledge halfway, she can combine it with her own What I have learned before, the progress will not be too slow.

Back at school, the school that had become a little deserted because of a large number of students leaving is now lively again. Many students are exchanging their experiences of this 'internship', and their interest is very good, but some of them have expressions on their faces. Bad...this time some students in the school where Zheng Yichen stayed also encountered accidents.

"This time we have recruited a lot of good club members. The next meeting won't be held around a table with a few of us." Qi Mengmeng patted her shoulder, although she was talking about the club's situation. , but his expression is a little distracted... which makes people feel a little uneasy.

Chapter 568 Image is not important

Zheng Yichen quickly understood where the uneasy feeling came from. While Qi Mengmeng was talking about the current situation of the club, her eyes were still looking for something in the crowd. She soon saw a figure. At this time, her eyes opened slightly. A bright light: "In addition to the basic members who cannot enter our circle, there is an additional outstanding student."

"In order to avoid being underestimated, I need you at this time."

"Why me?" Zheng Yichen asked. Don't ask what it was about. Anyway, he didn't think the starting point of Qi Mengmeng's words was good!

"Because you did not participate in the 'internship'. We have all been on the battlefield together, so we know each other well, so we will not be underestimated. And you... you must prove your strength to avoid future mistakes. When new club members join, they question your identity."

"I'll go! I'm just the logistics!"

"Huh? Logistics? In a few months, you will soon join the ranks of top students. Do you dare to say that you are a logistics? Aren't you afraid of being hated to death by the students in the school?" Qi Mengmeng rolled her eyes and pretended. To go too far would be to look down on all students below top students: "Is there any connection between logistics and combat effectiveness?"

"No? Generally speaking, those who manage logistics should be the easiest to kill, right?" Zheng Yichen asked.

"Oh? Do you want to be this kind of person too?"

"I always feel that you have another purpose." Zheng Yichen looked at Qi Mengmeng with a somewhat aware expression. The latter's face froze slightly and turned away from Zheng Yichen's face. The purpose... uh, ah, indeed Yes, it was mainly because Chen Mengxue had not had enough fun in the edge battlefield before, and then the president persuaded her to join the club on the road, but... she had conditions.

To see how strong the upper echelon of the club is, in Qi Mengmeng’s opinion, this is just a forced excuse. It’s obviously because her hands are itchy. Others in the school only heard her singing. In the circle of top students, for that woman , many of the top students kept her at arm's length for fear of being troubled by her, and none of them wanted to be someone's sparring opponent to become stronger.

It's fine if you say you win in a fight, but it's quite embarrassing if you lose. Not to mention that if the opponent really loses, he will challenge you again in the future. She grows up very quickly, and her personality is a hidden fighting mania. Qi Mengmeng said that she did not want to be targeted by such a person at all.

After discussing it with other people, even the president was involved, and the result of the discussion was Zheng Yichen... Look, Shen Meijia didn't want to be approached by this fighting maniac who looked like a literary girl in front of ordinary students. Yes, he won't worry about losing if he loses. But if he wins, he will be visited by her every now and then, or even without such a long interval. Will it be difficult for him to do things?

The same is true for Wu Shijie. He has just broken through his current level from the internship on the edge battlefield. He needs a period of time to stabilize his condition, and he does not want to be entangled with women. Qi Mengmeng and Zhao Qiwen... these two care about being torn apart by hands. Especially Zhao Qiwen, she said that she was a 'mage' who needed someone to protect her, so she didn't want to fight her one-on-one.

So in the end Zheng Yichen was pushed out. He was also the most suitable candidate. There was a time limit for going out every day, which meant that the woman couldn't keep looking for him. Moreover, due to his own situation, Zheng Yichen's fighting skills were not strong, and he was indeed needed. Even if Chen Mengxue's fighting style is violent when practiced by strong men, based on the level of competition, it is not so crazy that he can kill people...

He can withstand the pressure of limit-breaking training. A mere injury is not a big deal to Zheng Yichen. There is no one more suitable than him!

Moreover, judging from some of Zheng Yichen's physical information recently released on the school network, he is already very attractive!Anyway, not long after returning to school, some top students in the combat department are ready to deal with the challenges that may arise in the future, especially those top students ranked lower (unofficial statistics).

"I think you are deliberately trying to embarrass me!" Zheng Yichen said with a pulled face.

"Ah~ don't worry about such trivial matters. Anyway, many things in the club have already started. There are people dedicated to supporting and solving equipment and other problems. What you need to manage are those fine clothes. To be honest, you can't keep focusing on this area. no?"

"Okay then." Zheng Yichen calculated the time and found that there was still one week left until one month. Generally speaking, after more than 20 days, if he did not get the call of Samsara Kong, it would be almost the full rest time.

"That's it, you will be responsible for her from now on!" Qi Mengmeng slapped Zheng Yichen on the shoulder and hooked Chen Mengxue who was not far away. The latter walked over a little impatiently: " How's the discussion going?"

She doesn't really care about joining the COS club, as long as she can find opponents more easily here. Anyway, she can't let herself be bored all the time. Killing time by singing is really not as good as fighting...

"The result has been known for a long time, here you go! Your opponent."

Qi Mengmeng pushed Zheng Yichen to the front. Although he was a little reluctant, Qi Mengmeng had a little difficulty pushing him.

"Hi, see you again."

"It's really you." Chen Mengxue folded her arms and her eyes twitched slightly. She looked up and down at Zheng Yichen. She was not fooled by this guy's disguised appearance, and the body information he announced was not fake. It was slightly worse than her favorite opponent, but it was acceptable.

"Don't forget the time, I'm leaving first." Feng Lin came over and said to Zheng Yichen. Although she also wanted to see the battle situation after that, after learning some information from Qi Mengmeng, she felt that it was better to learn about it first. Check with your department to see the situation. It is estimated that there will be relevant announcements there.

If you don't go there early, who knows what tasks you will be assigned to. Top students are also students. Although they have more freedom, they must follow the school's arrangements in some situations. This is not absolute, it depends on what you do. I fought for it, since it was a major event involving human beings anyway, so I went late, and the related arrangements were really unavoidable.

Relatively speaking, the students of the combat department have it much easier. The problems caused by the marginal creatures mastering the technology of disguising themselves as humans are also a matter of the scientific research department and have nothing to do with them.

In the training ground, Zheng Yichen selected some weapons for training. These weapons had many specifications, but none of them had a sharp edge. However, even if it was used as a blunt instrument to hit someone, it would be very painful. Zheng Yichen chose a big sword and left here. .

When he arrived at the training ground, he found that there were already many spectators nearby...

Opposite her was Chen Mengxue, who had been waiting for a long time. The weapon used by the opponent was a giant sword... which was even more exaggerated than the shape-changing sword Zheng Yichen had used. Looking at her slender figure, the wielder For a heavy weapon of this scale, Zheng Yichen just wanted to say holy shit!
