Behind me is the entire history of mankind!

Chapter 9 The Results of Angrying a Scientist (for further reading)
Lincheng didn't see Wei Xian's speech until three days later. These days he has been running around looking for the supplies he needs, so he has no time to watch the group.

He smiled, but did not reply, he has returned to the origin base at this moment.

In front of me is a bunch of things purchased from major supermarkets, such as plant seeds, which exist in the gene bank of the origin base, and they are all excellent varieties after genetic improvement in the future, so there is no need to worry about the future, the main thing is to worry about It's fine now.

He divided the food into two parts, compressed biscuits and some marching rations that seemed to be stored for a long time, unpacked them, and put them in transparent airtight bags. Next, he will put the food in the freezer at the base, To disguise as the food originally stored in the base.

However, in fact, the base does store a lot of food, but the things that have been frozen for nearly a thousand years... Zombies are not as old as these things, and Lincheng doesn't want to eat them.

Then there are things like instant noodles, fresh vegetables, rice, and meat that are boxed and placed in the origin laboratory on the fourth floor for Lincheng himself and those scientists to eat.

It will not be open in the future, it is the place where he monitors those players through the chip in the player's brain, and plans this "game", where scientists study ether particles and other technologies.

These things cannot be known to players, so they will be kept secret.

After sorting these out, Lincheng looked at the hunting supplies and tools on one side, which included some axes, shovels, and some machetes, as well as the smell-masking spray that Li Chengfeng said.

And the two composite bows I bought from Taobao, imported goods, and the matching carbon fiber arrows, this kind of arrows are expensive, more than 300 RMB twelve pieces, I bought more than 30 pieces in Lincheng, but it is really easy to use easy to use.

It can be retracted and reused after being shot out.

Carbon fiber is a new type of high-strength, high-modulus fiber material with a carbon content of more than 95%. It is soft on the outside and steel on the inside. Its weight is lighter than aluminum, but its strength is higher than that of steel. It is corrosion-resistant and high-modulus. It is used in the military. Both industrial and civil use have great effect.

The bow and arrow is a quiet weapon, much quieter than a suppressed gun.The real silencer just makes the gunfire go from deafening to not so deafening.Although the arrows do not contain gunpowder, they have good penetration.Accuracy is fine at close range, but that's about it.

In actual combat, compared with firearms, the restrictions are very high, and it is also difficult to get started.

But for Lincheng, the advantage of this compound bow is that it is the only legal weapon that he can buy through formal channels on the land of Shenzhou.

Of course, if you take it on your body to show off your power in the street, you also have to go in and drink tea.

In fact, bows and arrows also have a lot of power, and there are special arrows such as incendiary bombs, tracer bombs, and high-explosive bombs. Obviously, they can shoot farther and more accurately when fired by arrows.

However, the accuracy of bows and arrows is too low, and the training cost is also high. However, in the "game", players can practice bows and arrows in actual combat by dying again and again, so Lincheng will not give up this line, that is The cost of carbon fiber arrows is too high.

However, he has ether particles, which should be able to relatively reduce the cost, but for specifics, you may have to ask those scientists, they know more than Lincheng.

But these are too far away from him. If you want to mass-produce, you must at least find oil, and if you want to industrialize, oil must be found.

Overall, he spent all his savings, but if the game company is established and starts charging, how much money does Lincheng want to make.

But now he doesn't care so much about making money. It's too stupid to care about making money when the world is doomsday.

He picked up the compound bow and looked at it carefully, with faint excitement in his eyes. Every man has a primitive instinct for hunting and a love for hunting tools, and Lincheng is no exception.

He used a body made of ether, and his main body was still lying underground. This transmission was also to test the possibility of consciousness transmission across time and space. Obviously, according to the activities of Lincheng in the modern world, this idea was successful. Yes, it also shows that Lincheng's "fourth natural disaster" plan is feasible.

He raised his head and looked at the sleeping cabins in front of him. At this moment, those scientists were swimming in the ocean of knowledge in "Prometheus".

He had asked Nuwa to notify them, and soon, the training cabin on one side slowly opened, and several bodies inside slowly opened their eyes, and then they saw Lincheng.

"You're back, kid." Einstein laughed. "How's the harvest?"

"It's okay, the first batch of players will arrive in a week, and we need to use ether particles to synthesize some virtual helmets that look like that using some materials in the base during this period.

Besides that, I bought a lot of food, and weapons against the bear. "

Tesla heard the sound and stepped forward, looking at the bow and arrow in Lincheng's hand, "Is this the one?"

Lincheng nodded.

"May I take a look at it?"

Lincheng handed him the bow and arrow in his hand.

Looking at the handsome shape of the bow and arrow, Tesla murmured with curiosity and inquiry in his eyes.

"Use the eccentric wheel or the round wheel to put the maximum torque in the middle section. It will save effort after pulling it apart. After releasing it, the eccentric wheel will increase the force to complete the launch. It's a good idea. How much is this bow?"

"75 pounds."

"With your current physical fitness twice that of ordinary people, you can use better ones." Tesla was thinking, and he pointed to the position of the arrow rest, "I can add an electric hydraulic booster system, and the bow and arrow will be moved by hydraulic means. power increased again."

"Are our existing materials feasible?" Lincheng asked.

"Do you still use your phone?" Tesla asked.

"It should be useless."

"There is remaining gasoline in the base, which can be used as a hydraulic system fluid after deployment, and the rest of the metal, I will see if I can remove it from other places.

In the memory of Dr. Lin Nuo, there is a graphene battery manufacturing technique, which is very suitable as a battery for hydraulic systems. "

Graphene is a new type of nanomaterial with a single-layer four-dimensional honeycomb lattice structure composed of carbon atoms.

It already exists in nature, but it is difficult to peel off the single-layer structure.Graphene is stacked layer by layer to form graphite, which is the pencil we use. Graphite with a thickness of 1 mm contains about 300 million layers of graphene.

A pencil scratches lightly on the paper, and the traces left may be several layers or even just one layer of graphene.

But ether particles can decompose and reorganize all substances. They can easily separate graphene from graphite and manufacture this battery.

"Compared with ordinary lithium batteries, graphene batteries have more than four times the storage capacity, are lighter in weight, and charge faster. In your era, it should not be widely popularized.

The cost mainly lies in the manufacturing process, but with ether particles, we can almost ignore it.

In fact, Dr. Lin Nuo still has a battery technology that can be called an energy revolution in his mind, but it is best to choose a lighter battery for loading on the bow and arrow to ensure flexibility, and the charging speed of this battery is also very impressive. "

Tesla said.

Lincheng quickly took out his mobile phone from his body and handed it to him, "Then I will trouble you."

"You're welcome." Tesla said calmly, "I want that stupid bear to know how stupid it is to piss off a scientist."

"Have you bought everything I asked you to buy?" Mendeleev asked.

Lincheng placed a box on the ground. None of the contraband Mendeleev needed could be bought, but if these chemical materials were bought in excess, suspicion would definitely arouse.

So now we can only do a small amount of purchase and production, and try to achieve self-sufficiency in this world.

Mendeleev opened the box and carefully took out the bottles and jars inside.

"With these, I should be able to prepare a nitroglycerin bomb, and then I will have more confidence in dealing with the bear."

Mendeleev and Tesla looked at each other, and both of them showed a tacit smile at the same time
