System into the end of the world

Chapter 177

Zhan Xuyang at the North China base was busy fighting wits with a group of people, and Yu Nan was not idle here, because the water purification plan that had been studied for several years had finally made significant progress.It is not water purification, but water source purification, the source of water.

The remaining zombie aquatic organisms in the Xinghai outside Xingcheng City have always been Yu Nan's heart disease. Because of its large area and connection with many underground rivers, it is impossible to clean it up thoroughly, so that this problem has been dragged on until now. .Whenever I think about it, Yu Nan always regrets it. I knew that I shouldn't have found a place so close to the water source to build a city. It's really nothing to do.

After countless drug studies with little success, the research team turned to biological research last year to manage aquatic organisms with water.This was also Yu Nan's original idea. Unfortunately, no suitable aquatic organisms were found, so the research team was formed.It wasn't until some researchers extracted a mutant plant gene that specifically eats zombies and fused it with the carnivorous mutant black fish that a new door was opened for them.

The mutated black fish not only maintains its previous carnivorous habits, but even crabs, snails, mussels, etc. have become its food.Its teeth became sharp and hard, and it looked like a piranha.Of course, although it has not been tested, maybe it is indeed a cannibal now.At first, it was not easy to achieve this. After the fusion, it was difficult to control what the black fish would eat. Sometimes it would eat anything, and sometimes it would not even look at the zombie creature.

After a long period of trial and error, the fused plant gene was finally stabilized, allowing the black fish to feed on zombies until it starved to death due to lack of food.Yes, starve to death.There is only one kind of food for the fused black fish, which is zombie creatures. If the water is cleaned up, then it will not be far from death.

"Is the genetics stable? If they regenerate small fish, can they still retain this characteristic?" Yu Nan touched the back of the black fish, confirmed that there was an update prompt in the system, and then withdrew his hand as if nothing had happened.In fact, it is not necessary to touch the real object to trigger the update program, but this point is not always effective, so if conditions permit, Yu Nan will directly touch it.

"Not sure, theoretically there is a 60% chance of heredity." Qi Lao replied to her.

"It's already very high." Yu Nan nodded, because she was too greedy. "Is this kind of fish easy to manufacture? If possible, I hope to make a batch as soon as possible and put them in the sea of ​​stars."

"As long as there are enough mutated black fish, about 10 can be fused a day."

Yu Nan thought for a while, "I'll take care of the black fish, please help me make a batch as soon as possible. Another question, if it's a marine creature, can you make it like this?" She raised her chin Pointing to the black fish in the fish tank.

"In theory, there is no problem, but if you change the type, you have to do it all over again, and the speed will not be too fast. What do you plan to use as a carrier?" Qi Lao frowned and thought for a while before answering.

"Jaws."

"Great white shark? Hiss..." Qi Lao accidentally bit his tongue.

Yu Nan showed a helpless expression, "You also know that many creatures in the sea have become very large now. It is impossible not to get a big white shark. It can't eat it if it is too small." Those crabs and shellfish are Those who have seen it, don't forget, there are still those fish that cannot go ashore.Whales, sharks, and king squids are all huge marine creatures. If they were enlarged in proportion to crabs, how big would they be?
Old Qi was full of confusion, but he also knew that what she said was right, "But there is no place for such a big guy."

Yu Nan waved her hand, "Don't worry, let's get the black fish out first, and you can give me...a hundred of them first." She thought for a while and said.It is estimated that there should not be too many zombie creatures in the star sea, but in terms of the size of the star sea, a hundred fish scattered in it is actually not enough to see at all.Let's clean it up slowly, anyway, it's time to wear cotton-padded clothes in two days, and no one should pierce the sea of ​​stars.I’ve been waiting for so many years, and it’s not too late for another winter. I’ll use instruments to test it in the spring of next year. If it’s all cleaned up, I’m ready to start putting fish in it.

"Xiao Nan, it's all recorded." Mu Dong walked over and said.

"I'll transfer the bonus to everyone's account when I get back." Yu Nan replied, and continued to talk to Qi Lao, "I'll have someone send the black fish over in the afternoon. You should also think about it in the next few days. Wait for the great white shark to pull it over." Which room should I put in when I come here?" It is impossible to have only one experimental subject, but this thing takes up space, so we can only send it here one by one.

"I don't have a device here to simulate the seawater environment." Qi Lao said immediately.

"I'll bring it to you together. If you have nothing else to do here, I'll go back first. If you need anything, please contact Assistant Mu directly." Yu Nan said.

"Okay, don't worry about it." Don't look at Qi Lao's various displeasures before, but as long as it is agreed, it will definitely make people feel at ease.

After leaving the research institute, Yu Nan went straight back to the downtown area.Twenty snakehead fish weighing about 3 to 4 catties were filled in a glass jar, and someone sent it to Mr. Qi.

"In the past two days, you take the time to fly the plane out for a tour, bring me back a box that is big enough, and then send the great white shark and the fish tank to the research institute." Putting Pudding in his arms, he sat down on the sofa.

"Okay." Mu Dong closed the door behind him, blocking the chilly wind from the door.

"There's someone you need to deal with, Xiao Mu, show her." Yu Nan stroked Pudding's hair and said.

Xiaomu turned on the light screen, which showed the detailed information of a man and a spy. He used the excuse of diverting in Xingcheng to inquire about news, and also used the computer in the hotel to spread rumors on the Internet.The matter of Xiaomu cannot be directly disclosed, so the information obtained from him cannot be sent directly to the intelligence department, and everything has to be turned around before it can be implemented.

Mu Dong went to the side and made a call, and when he came back, he told her that someone had been sent there.

Yu Nan listened to her report on today's work, left the documents to be signed, and asked her to go back first.

I bought some snacks from the mall, and Yu Nan read the documents while eating. "How are those people from country R?" She didn't look up, she just asked casually.The earthquake in country R this time was relatively severe. Many base houses collapsed and people were displaced.The giant zombie creatures that came ashore messed up the human settlements, so a group of people fled to the border of country Z by boat, and quietly settled down on the former site of the South China base.

"It's pretty safe at the moment. After all, they just arrived. It will take a while to settle down. Now they are harassed by the zombies around them." Xiaomu replied.

"Well, keep an eye on it. It's fine as long as they stay honestly. If they want to plot something else, they will send a notice to North China." Yu Nan got up and went to the bathroom to wash his hands, and came back to read what he had just finished reading. Several documents were signed.

"With me here, don't worry. By the way, do you want to report the recent incidents of cannibalism?"

"Huh? What's going on?" Yu Nan looked away from the document, frowned and looked at Xiaomu, "When did it happen? Didn't the greenhouse planting technology start to be promoted? Even if you can't eat the food that has been grown for a long time , but there should be vegetables, wild vegetables and the like? Plus some edible mutant animals and plants, it is impossible to be so hungry that you need to eat people!"

"It should have been a while," Xiaomu replied, "They are very careful. They usually trick people to their destinations before they start. If I didn't notice them when they tied people into the car this time, I'm afraid they would still be there." Will continue to hide."

Although Xiaomu's monitoring is powerful, it is impossible for him to watch everyone and every place in the world 24 hours a day.Therefore, there will be looseness and tightness in terms of strength, and overall monitoring will be implemented in places that are not important at ordinary times. Only when problems are discovered, will it be accurate to individuals or events.Therefore, it is purely normal that Xiaomu did not discover the problem at the first time.

"And I analyze that they don't eat people because they are 'hungry', but because human flesh is delicious." Xiaomu made a disgusted expression, and waved to show the heads of three of them.Their looks and styles are different, but what Xiaomu said is correct, looking at these three fleshy faces, no one will associate hunger with them.

"It's the same as dealing with anti-human organizations. Reporting within the local area must at least arouse the alertness of others." After Yu Nan finished speaking, he continued to look down at the document, obviously not wanting to continue this topic.In the past, I used to worry about trivial things in Star City every day, but now that everything is finally smoothed out, I start to worry about world peace again.Sure enough, the greater the ability, the greater the responsibility. The more I see and think, the more I feel that it is not as comfortable as when I was around the three meals a day at home.

Sure enough, man is such a creature.When he is ordinary, he will long to be outstanding; when he is outstanding, he hopes to be better; and when he really becomes a master, he will feel that the ordinary life is the happiest.People's desires are always endless, and you need to experience Qianfan to find out what you need most.It's a pity that it's too late to understand, people are getting old.

If it weren't for the golden finger of the system, which made Yu Nan struggle for decades, maybe she would not understand this truth until she really had gray hair and could no longer walk.Originally planning to work hard to save enough energy crystals, the thought of buying another real Star City suddenly faded away.

Is the real Star City that important?No one would worry about it except herself.The current facilities and defenses can't reach that height, but so what?Enough is enough.Even if the overall urban planning is not so beautiful and not so textured, it is also not an important issue.Everyone can plan slowly and implement it step by step. If it doesn’t work in one year, it will take two years, and if it doesn’t work in two years, it will take ten years. There are so many people in Star City, so don’t worry that it won’t get better and better.

That being the case, why did she make herself so tired?
Yu Nan laughed softly, threw away the signature pen in her hand, and stood up from the sofa.She walked to the window to look at the scenery for a while, then turned to Xiaoqi who was squatting in the corner waiting, "I want to eat French roast lamb chops tonight."

"Okay, mistress." Xiao Qi responded immediately.

Xiao Mu tilted his head and looked at his master, feeling that something was different.
