Chapter 388 Bow and Arrow Trading
Of course, Tu Hengyu was also injected with gene-enhancing drugs, otherwise Tu Hengyu, who was born in 2010, might not have the physical fitness to conduct alien exploration now!

This time when Liu Xiu landed on Pandora, he did not turn on the optical stealth mode but landed near Jack's tribe in a swaggering manner.

Jack had naturally seen Liu Xiu's Explorer spacecraft, so when Liu Xiu landed, the Na'vi people from Jack's tribe swarmed around him.

Of course, the first person to get off the spaceship was Liu Xiu. However, after Liu Xiu got off the spaceship, before Jack could speak, many Na'vi warriors from his tribe asked Liu Xiu in the Na'vi language if he had any more powerful bows and arrows for sale.

In response, Liu Xiu shouted in the language of the Na'vi people:
"Everyone, it is very difficult for our tribe to make such a powerful bow and arrow. So the bows and arrows I gave you before are just a token of friendship. In the future, the bows and arrows will not be free. If you want them, you must exchange them for something. I believe that you will not ask others to help you make bows and arrows for free!"

That’s right, there were times when the Na’vi people traded goods with each other, but although the Na’vi people of this period already had a unified language, they did not have currency.

Therefore, most transactions were conducted in the form of barter. For example, some Na'vi tribes were good at hunting, while others were good at weaving, so they would naturally exchange their prey and weavings with each other.

Of course, the Na'vi people of Jack's tribe naturally thought that Liu Xiu's request was very reasonable, so they had no objection to Liu Xiu's request for the superconducting minerals that could be found everywhere on Pandora.

Afterwards, Liu Xiu repeated the price quote for the composite bow made of carbon nanotube materials that he had defined, which was that the price of a bow was two hundred kilograms of superconducting ore. Of course, the quality of superconducting ore varies, so what Liu Xiu required was naturally the superconducting ore of Fushan quality.

However, he was worried that it might not be able to bear the weight, so Liu Xiu made a box, saying that he needed enough superconducting ore to fill the box in order to replace the bow, and then the arrows.

You must know that because the elastic force of the composite bow made of carbon nanotube materials is so great, the arrows made of ordinary wooden arrow shafts simply cannot withstand such acceleration. The consequence of using wooden arrow shafts is that the arrow has not even been shot out!

The wooden arrow shaft had been split in half by the bowstring made of carbon nanotubes.

Therefore, the arrow shafts used in such a powerful compound bow are naturally specially made high-strength aluminum shafts or carbon fiber woven shafts.

As for the arrowheads, they are made of high-strength and high-hardness tungsten alloy. Liu Xiu himself has tried it. Such arrows can easily penetrate three-centimeter thick ordinary steel plates within a hundred meters, and even one-centimeter thick steel plates within five hundred meters.

There is no way around it. This is the huge improvement brought about by high-tech materials such as carbon nanotubes. Therefore, if it is equipped with an explosive arrow shaft, it is easy to take down a mecha produced by Blue Star No. 2 with one shot.

Of course, Liu Xiu still gave the task of selling bows and arrows to Hao Xiaoxi. After wearing a translator, Hao Xiaoxi was still able to understand the language of the Na'vi people.

As for Liu Xiu, he took Li Yiyi and Tu Hengyu to find Professor Grace and introduced her:
"Hi! Dr. Grace, let me introduce you. This is Dr. Tu Hengyu, an expert in intelligence research on our Wandering Blue Planet. He is responsible for researching artificial intelligence and the digitization of human memory on our Wandering Blue Planet!"

However, when Grace heard what Liu Xiu said, she shook her head and said:
"You, Wandering Blue Star, also want to digitize human consciousness so that humans can live forever on the Internet!"

Grace shook her head and said, "You humans wandering on Blue Star have also embarked on the same quest for immortality as us. However, in fact, this kind of immortality is not immortality at all. It is just a program of a human memory replica. We have tried this experiment before, but the intelligent program or human consciousness copied from human memory is completely different from the judgment made by real humans! Immortality is not as simple as humans think!"

Liu Xiu was not surprised after hearing Grace's words. After all, they had already created something like Avatar, so it was naturally not difficult to digitize human memory.

After all, Blue Planet No. 2 is a human planet controlled by a group of tycoons, so those tycoons are naturally very interested in immortality. Just like before Liu Xiu traveled through time, someone replaced six hearts to prolong his life.

Tu Hengyu nodded in agreement with Grace's words:

"That's true. We have also discovered that everyone's brain wave frequency is slightly different even when they are in the same emotion. And so far we have not found anyone with exactly the same brain wave frequency. Even twins have slight differences!"

·······
After that, Tu Hengyu talked with Grace about many topics such as the meaning of life, the essence of life, and even whether there is a soul.

Of course, Grace even talked to Tu Hengyu about whether the Jack who changed his body was still Jack himself, and whether the god mentioned by the Na'vi, that is, the so-called god of Pandora, really had the ability to make people change their bodies.

Or to put it simply, Jack is no longer the original Jack, but just a clone who has all of Jack's memories.

Of course, the issues about life and soul that Grace and Tu Hengyu discussed also made Liu Xiu himself begin to reflect on whether he was really the Liu Xiu of the original world, or whether his current self was just a memory copy of that world, somewhat similar to Miles in Avatar 2.

After all, Miles is so similar to Liu Xiu and Jack! Once the original body dies, a copy is made and then inserted into the spare body. Isn't this the completion of the time travel?
Therefore, perhaps Liu Xiu himself also understood that his time travel was most likely just a boring farce of a higher civilization.

Although he felt helpless, Liu Xiu himself was also asking himself in his heart whether this savior system was like this.

But unfortunately, Liu Xiu's inquiries fell on deaf ears, as if this cold savior system simply ignored him.

Liu Xiu, who had no idea what to do with the system, could only sigh helplessly, and then asked Tu Hengyu to stay here. Then he went to Jack again and said to Jack:

"Jack doesn't have much time left for us. This time I went back and discussed with the top leaders of Wandering Blue Star. We finally reached a consensus and decided to help the Na'vi on Pandora to fight against the alien invasion. However, we need a large amount of superconducting ore to improve our weapons so that we can fight against the aliens. But we are willing to barter with you Na'vi on Pandora for high-tech weapons!"

In response to Liu Xiu's words, Jack nodded and said:

"I will bring my tribe to promote your bows and arrows. Every Na'vi is a good hunter and attaches great importance to bows and arrows. So you don't have to worry about not being able to sell your bows and arrows!"
