Chapter 9 Important Survival Wisdom

About "Why Yuki is so excited", Xiang Shan is of course well aware of it.

The kid was so happy because Xiang Shan promised to teach him some skills.

Xiang Shan admitted that exposing his identity was somewhat risky.He even considered the worst-case scenario—that is, the word "chivalry" has been completely distorted in this era, and chivalrous men have long since lost their reputation.In this case, he even needs to knock Yuki out and get out of town.

But he really lacks common sense about this weird era.He really needs someone from this era to help him.In addition, he couldn't complete some brain transformations by himself.To recover his martial arts, he needs a helper.

Yuki is currently the only person Xiang Shan can trust.Xiang Shan had been with him for a few months, and he knew that the child was kind and intelligent.He also has enough curiosity to want to understand the world.

From Xiang Shan's point of view, this child has the value of being trained as an assistant or even an apprentice.

As for the matter of revealing his identity, Xiang Shan has also gone through certain considerations.

After weighing the risks and benefits, Xiang Shan finally chose to confess.

A few minutes ago, Xiang Shan saw the expression on Yuki's face with his own eyes, from astonishment, fear to relief.

"I see Xiang Shan, you are angry about what happened to the workers." Yuki said: "I believe you are a good man and a good knight."

Later, Xiang Shan asked Yuki where he could buy parts and borrow a set of special tools.Yuki brought Xiang Shan to Dr. Schultz.

"Well, most of the parts you need are very common. I have most of them here." Dr. Schultz glanced at Xiang Shan's list and nodded: "However, there are a few of them that are not cheap ,In this case……"

"Don't worry, I have a way to pay." Xiang Shan took out a spine from the package he carried with him.This spine has a silver-gray luster and is heavy, unlike the accumulation of calcium and protein, its density is close to that of metal.

This is what Will Granddog left behind, a vertebra.

Humans do develop such spines.This is what Xiang Shan just recalled.In the 21st century, human beings have made great progress in molecular biology and genetic engineering. Human beings can use genetic modification to allow the body to synthesize proteins containing metal elements.

If a person uses a modified virus to graft a new gene segment into his body, and insists on taking anti-immune drugs for a period of time to suppress the rejection between the original body and the new protein, then the composition of this protein The cells will gradually replace the original cells, and eventually people will evolve from "Homo sapiens" into a brand new creature.

And this new Hominin species transformed from Homo sapiens has a stronger ability to adapt to cyber prosthetics.The metal-based proteins in his body will form natural wires and resistances, the threshold of "brain-computer interface" will be infinitely lowered, and the ability of cells to resist mechanical damage will rise sharply, and the hardware implanted in the human body will no longer trigger the explosion of surrounding cells. necrosis.

——This may also be the reason why Xiang Shan was able to wake up again after being in a coma for countless years.

From a certain point of time, the process of human prosthetics ran wild like a wild horse.

Xiang Shan no longer remembered any more details.But he also remembers that in his day, the spine was still a key thing.The spine after metallization is a natural data transmission line, the channel capacity is very large, and it is naturally compatible with nerve signals, without further adjustments.Many cyber transformations will retain the brain, cerebellum, medulla oblongata, and spine.

And now, this technique is still used in Will Granddog's prosthetic body.

Xiang Shan remembered that Yuki's mother, Yulia, had sold spines.This stuff is still worth a lot today.

Dr. Schultz was taken aback: "Are you going to sell this thing?" He looked at Xiangshan's stickman-like prosthetic body: "You don't plan to use it yourself?"

Xiang Shan pretended to be indifferent and said, "There is no medicine."

"medicine?"

"It's the kind...what you need when you change your spine...what?" Xiang Shan asked tentatively.

After receiving the metallated gene fragment, the cell's anti-apoptosis ability increased, and the receptors on the original cell membrane surface were all rewritten, and the earth's native viruses could hardly harm new humans.In addition, the increase in body temperature also makes humans immune to most old germs, fungi, and parasites.But this does not mean that people do not have rejection reactions.Using someone else's spine, the body will also have a rejection reaction.

——Of course, this is what Xiang Shan remembered from that era.

Xiang Shan didn't know how far the earth's technology had advanced after he fell into a coma.Yuki is not very clear about this kind of professional question, so he can only come to test Dr. Schultz.

Dr. Schultz nodded: "Indeed...the anti-messenger soaking agent is really difficult to get."

He didn't doubt too much.After all, the average person does not need to replace the spine in their lifetime.

"Yes, yes, Reverse Messenger Soaking Agent!" Xiang Shan nodded, pretending to have suddenly realized - fortunately, he has no face and skin now, and even the sound generator is cheap without emotion, and he doesn't need acting skills.

——Anti-messenger soaking agent, a word I have never heard of before... Messenger, is it related to messenger RNA?

Xiang Shan himself is an engineer.But he vaguely remembered that he had a friend who was engaged in biology, and he had talked about related topics with him.

——Central dogma, DNA records genetic information into messenger RNA, and then the messenger RNA is transcribed into the long polypeptide chain, and the polypeptide chain is folded by organelles to become protein...reverse transcriptase?No, it shouldn't be...

——Can this process be further reversed?

It seems that technology is still improving.Xiang Shan judged so.In his time, except for special cases such as prions, other life activities basically followed the expression process of biological genetic information such as the "central dogma".There is almost no way you can reverse this life activity in the cells of a higher organism.

"However..." Dr. Schultz turned the list to the end and looked at it: "I really don't have these parts here... This kind of specification should not be applied to prostheses, right? There is also the last item, the thickness is different. Iron sheets over one millimeter and less than three centimeters wide? If you want to find these things, you'd better go to the waste parts recycling bin at the east end of the town."

Xiang Shan explained: "This is used to make some... auxiliary tools."

"From this list, you shouldn't have received professional training, right?" Dr. Schultz shook his head: "Many of your specifications are not standard. I don't know what kind of prosthetic body you plan to make, but, Warrior's professional prosthetic body is a rare thing after all. I don't want you to waste your hard-won good parts. How about this, do you want to go online and look at the blueprint?"

"Internet access?" Xiang Shan was startled.He remembers that for a time such a thing as the Internet disappeared because of the war.He really didn't expect that there was such a thing as a network signal in this shabby-looking world.

"Our town is relatively broken, and there is no public network signal. But I set up a private one at home. You should be able to receive it when you sit in the middle of the living room. I can give you a one-time access password..."

When he said this, he paused: "However, you'd better not download things casually, and don't open previews for holographic signals..."

Xiang Shan was indeed somewhat moved.

But he finally shook his head: "No, doctor, thank you for your kindness. The Internet must be very expensive, and I can't take advantage of you for nothing."

"That spine has already made me a lot of money." Dr. Schultz patted Xiangshan on the shoulder: "Besides, you also saved my town. I really have to thank you."

"No, I'm not used to being favored for no reason. If I need it, I will borrow your net again." Xiang Shan still rejected Dr. Schultz's kindness.

Dr. Schultz did not invite again.He quickly found all the parts that Xiang Shan needed, and lent Xiang Shan a professional biological tissue surgery tool.

After confirming that he was walking away from the mountain, Schultz went upstairs.

The mayor is in a room upstairs.

"Uncle, he didn't go online." Schultz looked strange: "Why do you want me to remember to invite him to go online?"

Dr. Schultz really didn't understand Uncle's request.Still, he complied.Uncle is the most knowledgeable person in this town. When he was young, he traveled all over the world and knew some secrets.

"Dresden..." the mayor called Schultz's name: "Turn off the Internet first."

Schultz nodded, and directly issued instructions through the brain-computer interface to disconnect the home network.

Anyway, he usually saves network costs in this way.

"Did you know? Dresden." The mayor seemed to be recalling the past: "When I was young, I offended an official and had to go far away."

Schultz nodded: "Indeed, but you are lucky, the official died later..."

"He was assassinated by a knight." The mayor was silent for a moment, then said, "I called that knight..."

"What?" Schultz screamed.

Colluding with knights is a serious crime against Dyson's principle!

"I didn't collude with knights. I just happened to meet a knight in the wilderness and asked for help." The mayor snorted: "Your grandfather, my father once told me that a thug like a knight It's actually very useful. As long as you show humility to them, they won't give you a hard time. Instead, they will assassinate officials they think are guilty for some evil sense of honor-which they are actually very good. This , is our very important survival wisdom.”

Schultz exclaimed: "You never told me..."

"That was before...the fewer people know about this secret, the better." The mayor was silent for a moment: "But now, the situation is different. The tax officer only accepted eighteen babies, which is lower than the standard ratio. He wants How to deal with us, we don't know. Maybe we can only rely on the power of 'Xia Ke'."

Schultz immediately understood: "You mean... Shan is a knight?"

"I don't know what Mr. Shan did before he lost his memory, but I know that all knights have a habit, they don't connect to the Internet casually. I spent a few days with a knight, and before they go online, they must Prepare for a long time." The mayor said in a low voice: "I don't know if Mr. Shan is a knight. However, he can indeed fight—especially after obtaining the warrior prosthetic body."
