Behind me is the entire history of mankind!

Chapter 7 The Swaying Tree in the Wind

A slightly old voice came from the end of the tunnel. People turned their heads, and at the end of the darkness, a thin figure in a suit came out. It was Tesla's body.

"Yo, Tesla, how does it feel to die once?" Mendeleev teased.

"It's not good." Tesla touched his neck. Just now, his neck was torn apart by the giant bear. "It didn't hurt as much as I imagined, but I never want to remember it."

"Regarding this, you can try to open your own UI, that is, open the user interface silently." Lincheng said.

Einstein followed Lincheng's statement with some doubts, and soon, a virtual projection appeared in front of them, with a three-dimensional stereogram, on which real-time monitoring of various data of the body, such as heart rate, was displayed on the arm. On the road, he was scratched due to the haste of running just now, and was also marked.

On the other side, there are some physical qualities, which are very complicated, including at least a thousand pieces of data including cell activity, muscle density, and nerve response speed.

"Data quantification is an important foundation of the game. This is the way to install a special chip in the brain using the same virtual projection technology inside the base. It is directly projected on the iris, and only you can see it.

Nuwa can monitor each player through these chips.

These chips are things that already existed in the base, and they can be directly linked to the "Prometheus" system to learn the knowledge in it.

The first batch of new humans basically had this kind of chip implanted in their brains. The founders of the "Tinder" project originally planned to use this chip to instill the knowledge of human civilization into the minds of those new humans.

Nu Wa re-edited the system in the chip and loaded the UI system.

The current UI is only the first version, and the data is still too cumbersome. Next, I plan to use Nuwa to integrate these body data into five to six items, such as strength and agility.

Of course, you can look under the character, where there is a pain adjustment button.

Some human pituitary glands can secrete endorphins, which have an analgesic effect like morphine. In reality, some "painless" people secrete endorphins three to four times more than normal people.

The human body I designed can adjust the pain sensation by regulating the secretion of endorphins. In addition, the fatigue of the human body will be weakened as much as possible. Although the body will not feel tired, the body will gradually become dull as it reaches the limit. .

Secondly, I have also added an emotional passivation system to the human nervous system, so that people will not have psychological shadows after killing people or animals or dying. This is the future "player" template. "

"It's really a "game"." Planck said with emotion.

"How many chips of this kind are there in the base?" Einstein asked.

"There are still [-] storage capacity inside the base, and there is a chip production line and corresponding technology, but the key point is that we lack semiconductor materials and photoresist for making chips." Lincheng Road.

Einstein nodded, "It shouldn't be difficult to copy."

"What happened to the bear just now?" Tesla said from one side, "Humans are not in the diet of bears, why did they suddenly rush out and directly attack us?"

"Animals don't care about any diet when they're hungry," Plank said.

"It has wounds on its shoulders and back, some of which look like gunshot wounds, and some of which look like burns. It should have encountered humans before, so it should be very sensitive to the smell of humans." Lincheng said.

"Speaking of which, if there is nothing wrong with my new brain, the bear just now was a bit too big." Mendeleev said, "Even the polar bear is not that big."

"Standing up and visually measuring more than four meters." Tesla nodded, "The highest standing height of a polar bear is only about three meters."

"On this point, Nuwa also told me that there are alien groups in the outside world. If they are just ordinary animals, they may not be able to form a stable ecological circle against them. Therefore, He used a longer prehistoric ecological circle. Mixed modern ecosystem, calculated and delivered.

The bear is an extinct giant bear with fine teeth. It is 70 years ago and is the largest known bear on earth. The oxygen content of the purified world is a little higher than before, which is completely in line with their living environment . "Lincheng spoke from one side.

"So, that is to say"

Lincheng nodded, "Elephant-sized giant ground sloths, Titanoboa constrictors up to 15 meters in length, Prussian crocodiles up to ten meters in length, mammoths, sabre-toothed subfamily, and even The three largest and most ferocious felids that ever existed, the saber-toothed cat, the vicious lion, and the cave lion, all existed in this era."

After a long silence, Einstein said with emotion, "Is it a prehistoric creature that has long been extinct? Although this "Tinder" project has been rushed, it is extremely grand in terms of the time it takes and the scale. Big plans."

"But this plan still failed." Lincheng said.

"No, it hasn't failed yet. Our arrival is the last piece of the puzzle." Plank said.

Several scientists around also nodded, and then Mendeleev said, "However, this ecosystem is not friendly to humans."

"Although the size and strength of human beings are not comparable to them, we have the most powerful weapons in the world. Wisdom, as well as a pair of hands full of creativity.

Our ancestors once competed with these creatures at the same time, but successively, we exterminated cave lions, saber-toothed tigers, and mammoths. In this era, we possess much more advanced technology and weapons than prehistoric eras. We have More advanced knowledge than that era.

Standing on the same arena again, I think we should not lose. "Lincheng Road.

"You're right, kid." Einstein said with a gentle smile, "Human beings have been able to defeat these prehistoric creatures in the past and stand at the top of the food chain, and this time they will definitely be able to."

"Okay, let's start planning. Dr. Lin Nuo's brain is on the fourth floor, and there is a local area network in the base. You can communicate with her through the chip and learn the knowledge stored in her brain.

Although she is a genius in physics, she has dabbled in other fields of knowledge and has made some achievements.

And I will go back to my time to complete the plan of extradition of player consciousness. "

"I can't wait to travel the ocean of knowledge." Einstein laughed.

"Nuwa." Lincheng read out a name, and a virtual projected light appeared on his left eye.

Under everyone's gaze, a graceful figure slowly appeared beside Lincheng.

Ordinary people rarely have a slender figure, dark skin, long silver-white hair, and a rather tall figure.

The eyes are also a little bigger than human beings, like glass, crystal clear, especially the pair of pointed and long ears, which are very conspicuous, and there are two beautiful pendants hanging on them.

Like an elf jumping in a mountain stream, her hair is like a streamer wrapped around her head, very beautiful. This is the image set by Nuwa in the program. Lin Nuo used to have a daughter who died on the front line, and Nuwa Wa just used her daughter's appearance, but made modifications, such as eyes and ears.

After all, Dr. Lin Nuo never thought of finding some existence to replace his daughter.

"She is Nvwa, the artificial intelligence of this base. I will come back in a few weeks. If you have any urgent problems, you can notify me through Nvwa. She is already trying to use ether particles to construct a space-time channel to transmit Data, can communicate with me through this pocket watch."

Several scientists nodded.

"Do you need me to buy anything?" Lincheng asked.

"Help me buy a set of chemical preparation tools, buy some basic chemical materials, such as glycerin, nitric acid, sulfuric acid and the like." Mendeleev said.

Lincheng's expression froze, he knew what he wanted to do with this familiar material.

Although these things can be obtained through various channels, there is no problem buying them individually, but if you buy them together, the water meter will be checked easily.

He nodded, "Xing, I'll think of a way. There is a chemical laboratory on the fourth floor, so you don't have to worry about the tools."

Finally, he looked at Einstein, "What about you?"

"Dr. Lin Nuo is a physicist himself. The many facilities and computers in this base are enough to answer many of my questions. I guess you can't buy what we want." Einstein laughed.

"And you, Mr. Tesla."

"My research is far behind this era. As an electrician, I obviously don't need to repair the wires here." Tesla laughed at himself.

After a pause, he said, "As long as that fine-toothed bear stays around here, our plan will be hindered. We need to buy some weapons."

The origin base does have some guns, but it is different from the origin laboratory on the fourth floor. Because there are many important instruments there, there is an environmental maintenance system, and most of the instruments are well maintained.

But the firearms placed on the second floor are different. They have been corroded by the humidity in the base. It is estimated that even if there are bullets, it will be good if they can be opened without exploding. Maintenance is equivalent to redoing.

However, ether particles can refurbish it, but you need to find the design drawing of the firearm, or find a researcher who is very familiar with firearms, and the bullet problem also needs to be solved. There is a way for the shell material, but the preparation of gunpowder requires some effort. .

Lincheng smiled awkwardly, "You think highly of me, my country can't buy weapons through legal channels, and I obviously can't go abroad to buy guns, which requires some troublesome procedures."

"You can try to pick up a gun on the battlefield of World War II." Tesla teased, "If you're lucky, you might be able to pick up a tank."

Mendeleev raised his eyebrows, "World War II?"

Tesla nodded, "The Second World War was several times larger than the First World War, affecting Europe, Asia, Africa, and the Pacific region. The economic crisis originating from the world intensified internal and external conflicts, and two major political and military blocs were formed."

"A lot of people died." Einstein's eyes were deep. "Fortunately, we won in the end."

Mendeleev nodded solemnly. He died before the two world wars, but this does not mean that he did not know the tragedy of the war.

None of the scientists present had a very good expression on their faces. This is a serious problem.

Several people present were anti-war activists. Just take Einstein as an example. In April 1914, Einstein accepted the invitation of the German scientific community and moved to Berlin. In August, World War I broke out.

Although he lives in the birthplace of the war.Surrounded by war advocates, he resolutely expressed his anti-war attitude.

In September, Einstein participated in the founding of the anti-war group "New Fatherland Alliance". Even though this organization was declared illegal and a large number of members were arrested and persecuted and went underground, Einstein still resolutely participated in the secret activities of this organization .

In October, under the manipulation and instigation of militarists, the German scientific and cultural circles published the "Declaration of a Civilized World", defending the war of aggression launched by Germany, advocating that Germany is above all else, and that the whole world should accept the "true civilized world". German spirit".

There were 93 people who signed the "Manifesto", all of whom were famous scientists, artists and pastors in Germany at that time.Even Nernst, Roentgen, Ostwald, Planck, etc. all signed on it.

When Einstein was asked for his signature, he flatly refused, but at the same time he resolutely signed his name on the anti-war "Letter to the Europeans".

Declaring: "Europe must unite to protect its land, people and culture" and to launch a "massive movement for European unity", this declaration was widely circulated among the faculty and staff of Humboldt University, but only four people signed it.

However, the only lesson of history for mankind is to forget the lesson of history.Less than ten years later, the Nazis swept across Germany, and German scholars collectively suffered severe concussions, forgetting the past affairs of the previous dynasty and following the "Führer" closely again.

When Einstein stood up to counter the Nazis, many scientists actually thought he was "excessive". At that time, even Lao He said to Einstein: "After all, there are only a small number of people who want to become Nazis."

On March 1933, 3, Einstein, who had just returned his German citizenship, announced in the United States: "As long as I have a choice, I will only stay in countries with political freedom, tolerance and equality before the law for all citizens... Germany These conditions are not available at present!"

Listening to several people discussing World War II, Planck smiled wryly. The Nazis ran rampant in Germany and poisoned Europe. These silent and cowardly German intellectuals cannot escape the blame.

Einstein seemed to be aware of the strangeness of this long-time friend beside him. He patted him on the shoulder, "Science has no borders, but scientists do. Science should not be coerced by politics, but as long as people who study science are people, it is difficult to escape." the dirty politics of those in power"

Although Einstein despised the cowardice of German scientists, he could understand the behavior of his friend.

He is relatively idealistic, while Planck is more realistic. Germany is his home, where his family and friends are all.

In fact, Einstein himself was expelled from school because he opposed the Nazis. His wife, Roaisha, and two stepdaughters were severely interrogated by the police. His Berlin residence was searched, and his bank deposits, safes, yachts, and Kaput wooden houses were confiscated. If he hadn't walked fast, he might have been persecuted by the Nazis.

Compared with the rest of the silent scientists, Planck at least went to the "Führer" to plead for mercy in order to protect Jewish scholars. Although he was hot-faced and cold-ass, he was almost expelled from the Führer's Palace.

"I have been trying to justify our silence in the past. I feel that the Nazi was like a gust of wind sweeping across the country. We were helpless and could only be at the mercy of a tree in the wind."

Planck's gaze was deep.

"But just like the famous saying in Kant's "Critique of Practical Reason"-conscience is our own awareness of the existence of the inner court!

I'm not as good as Lao He, I'm just an ordinary intellectual who bows to power. "

Lincheng looked at Planck, the Newton of Germany, winner of the Nobel Prize in Physics in 1918, pioneer of quantum theory, president of the Royal Wilhelm Society, and a great leader of the German scientific community.This well-educated aristocratic professor is gentle, gentle and approachable, and has won the love of Kaiser Wilhelm II and the prostitutes.

The wealth he left to mankind is incomparable to most scientists. He is able to stand up straight and look directly at anyone, but at this moment, he looks so humble.

But everyone knows who and what is really wrong.

"It's all over." Lincheng said, "The flames set off by the Nazis have been extinguished. Human beings can't forget history, but they can't just focus on history. There is still a long time to come, and we should look forward."

Several scientists nodded.

"So far, we haven't figured out the real principle of ether particles traveling through space and time, and whether they will consume energy." Einstein said.

"Even if the ether particles travel through time and space in a more ingenious way, there is no need to consume a huge amount of energy, and it is impossible to consume nothing, and whether carrying items from different time and space has an impact on time and space, so, carrying a large amount of materials from the past, I think It is recommended to take a long-term plan and buy some necessary living supplies first."

"That's true. It's better to be cautious. World War II is too dangerous. Moreover, if you want to deal with that fine-toothed bear, guns may not be the best way." Tesla murmured softly.

"It has encountered humans and has multiple gunshot wounds on its body. Since it is so sensitive to humans, it should be alert to gunpowder. The sense of smell of ordinary bears is several times that of dogs. The smell of gunpowder is specific and not appropriate.

So, if you can, it might work wonders to use some more primitive weapons, such as bows and arrows. "

"No matter what, guns should be better than bows and arrows." Lincheng said.

"The sense of smell of polar bears is seven times that of humans. They can smell the smell of seal fat roasted 3.2 kilometers away, and they can accurately judge the location of their prey by their sense of smell from several kilometers away.

If you hold a gun, according to the specificity of the gunpowder smell, the bear can detect your entry within ten kilometers, and it will be even more powerful if the wind is down.

And if you are noticed by that bear, it means that it has the initiative. It can consider hiding or hunting you according to the number and strength of the enemies.

You become prey.

As long as they are predators, how to hunt and kill animals in the most efficient way is the first thing they think about. Cats have learned to ambush, crouching down to approach animals on tiptoe, and then pounce on their prey in an instant with explosive force.

Even pack animals like hyenas and wolves patiently plan, watch, bide their time, and hunt when you are most tired and weak.

The vast majority of bears today are herbivorous, or eat honey and fish, so bears have evolved powerful fishing skills.

Polar bears, on the other hand, evolved their fur into white for the convenience of hunting animals.

The fine-toothed bear is undoubtedly a carnivorous creature, but it has no protective color, and it is not a herd animal, which shows that they also have the ability similar to ambush.

Although it is nearly four meters long, its shoulder height is only two meters high. The forest is thick with bushes. If it bends down, humans cannot even detect it with the naked eye from 60 meters away.

Within 60 meters, the speed of ordinary bears is 55 kilometers per hour, and the explosive speed in short distances even far exceeds that of the top Olympic champions, and they can reach your eyes in a few seconds.

You should have seen the speed of the slender-toothed bear. Its limbs are slender, and its explosive power will only be stronger.

Moreover, even if you find out, with the visibility of the forest, the human aiming distance is actually only 50 meters to 20 meters.

In these few seconds, under the pressure of an ancient behemoth rushing towards you, you must shoot at the fastest speed, and you must also shoot deadly parts such as the head and lungs.

Even a top hunter can't do this, let alone a group of ordinary people?

Never underestimate these predators, there are not a few humans who have died with guns at the hands of these animals.

If you have a bow and arrow, as long as your breath is concealed properly, you have time to dig traps and climb trees to wait for rabbits in the animal way.

From a prey to a hunter, even if the bow and arrow skills are not good, at least there is time for you to prepare for aiming and adjust your mentality to shoot. "

Lincheng nodded, "I understand."
