Cyber Heroes

Of course, Xiang Shan knows "Why Yuuki is so excited".

This child is so happy because Xiang Shan promised to teach him some skills.

Xiang Shan admitted that it was somewhat risky to expose his identity. He even considered the worst-case scenario-that is, the word "chivalrous" has been completely distorted in this era, and the knight has no prestige at all. In this case, he even needs to stun Yuki and leave the town.

But he really lacks common sense of this weird era. He really needs a person of this age to help him. In addition, he could not complete some brain transformations alone. To restore martial arts, he needs a helper.

Yuki is currently the only person Xiang Shan can trust. Xiang Shan has been with him for a few months. He knows that this child is kind and smart by nature. He also has enough curiosity to understand this World.

From Xiang Shan's eyes, this child has the value of training as an assistant or even a discipline.

For the disclosure of his identity, Xiang Shan has also taken 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 saw Xiang Shan that you were angry about what happened to the workers." Yuki said: "I believe you are a good man, a good knight."

Then, Xiang Shan asked Yuki where he could buy parts and borrowed a set of special tools. Yuki took Xiang Shan to Dr. Schultz's place.

"Well, most of the parts you need are very common. I have most of them here." Dr. Schultz glanced at the list listed by Xiang Shan, nodded: "However, there are Several prices are not low, so..."

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

This is the relic left by Will Grand Doug, a spine.

Humans do indeed grow such spine. This is what Xiang Shan just recalled. In the 21st century, humans have made tremendous progress in molecular biology and genetic engineering. Humans can use genetic modification to allow their bodies to synthesize proteins containing metal elements.

If a person uses the modified virus to graft a new gene fragment into his body, and insists on taking anti-immune drugs for a period of time to suppress the rejection reaction between the original body and the new protein , Then the cells composed of this protein will gradually replace the primordial cells, and finally let people evolve from "Homo sapiens" into a whole new organism.

And this new Hominid species transformed from Homo sapiens has a stronger ability to adapt to cyberprostheses. The metal-based proteins in his body will form natural wires and resistances. The threshold of the "brain-computer interface" is infinitely lowered. At the same time, the ability of cells to resist mechanical damage has risen linearly. The hardware implanted in the human body will no longer cause the surrounding cells. Necrosis.

——This may be why Xiang Shan can wake up again after countless years in a coma.

From a certain point in time, the process of human prosthesis has been running like a wild horse running away.

Xiang Shan can't remember any more details. But he still remembers that in his time, the spine was still very important. The spine after metallization is a natural data transmission line, with a very large channel capacity and a natural fit with nerve signals, without further adjustments. Many cyber transformations will retain the brain, cerebellum, medulla oblongata, and spine.

And now, Will GrandDoug's Martial Artist prosthesis still uses this technique.

Xiang Shan remember that Julia, Yuki's mother, sold the spine. This thing is still very valuable today.

Doctor Schultz was taken aback: "Are you going to sell this thing?" He looked at Xiang Shan Matchstick People's normal 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...that you need to change your spine...that What?" Xiang Shan asked tentatively.

After accepting the metallized gene fragment, the cell's anti-apoptotic ability increases, and the original receptors on the cell membrane surface are all rewritten, and Earth's native virus can hardly harm new humans. In addition, the increase in body temperature also makes humans immune to most of the old germs, fungi, and parasites. But this does not mean that there is no rejection reaction. Using other people's spine, the body will also produce rejection reactions.

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

Xiang Shan doesn't know how far Earth's technology has improved after he was in a coma. Yuki is not very clear about this kind of professional problem, so he can only come to test Dr. Schultz.

Doctor Schultz nodded: "It's true... The reverse messenger infusion is really not easy to handle."

He didn't doubt too much. After all, an ordinary person does not need to replace the spine for a lifetime.

"Yes, yes, reverse messenger soaking agent!" Xiang Shan nodded, pretending to be suddenly enlightened-fortunately he has no face and skin now, and even the sounder is a cheap commodity that lacks emotion and does not require acting skills. .

——Reverse messenger soaking agent, a word that has never been heard... Messenger, is it related to messenger RNA?

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

——The central law, DNA enters genetic information into messenger RNA, and then messenger RNA is copied into long polypeptide chains. The polypeptide chains are folded by organelles and become proteins...reverse transcriptase? No, it shouldn't be...

——Can this process be further reversed?

It seems that technology is still improving. Xiang Shan judged this way. In his time, with the exception of special cases such as prions, other life activities basically followed the "central law", which is the process of expressing biological genetic information. You can hardly reverse this kind of life activity in a high level biological cell.

"But..." Dr. Schultz turned the list to the end and looked at it: "I really don't have these parts here... This specification shouldn't be applied to prostheses, right? And the last one, iron sheets with a thickness of no more than one millimeter and a width of less than three centimeters? If you want to find these things, you'd better go to the waste parts recycling bin in the east of town."

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

"From this list, you should have no professional training, right?" Dr. Schultz shook the head: "You have a lot of The specifications are not standard. I don’t know what kind of prosthesis you plan to make. However, the professional prosthesis of Martial Artist is a rare thing after all. I don’t want you to waste your hard-earned parts. Let’s go. , Would you like to go online to see the design drawings?"

"Go online?" Xiang Shan was taken aback. He remembered that this thing on the Internet once disappeared due to war. He really didn't expect, this seemingly tattered world, there is actually the network signal this thing.

"Our town is relatively broken and there is no public internet signal. But I have a private one in my house. You should be able to receive it if you sit in the middle of the living room. I can give you a one-time access code... …"

Speaking of this, he paused: "However, you'd better not download things casually, and do not open the preview of the holographic signal..."

Xiang Shan does have several points of intent.

But he finally shook the head: "No, doctor, thank you for your kindness. The Internet must be very expensive, I can't take advantage of you in vain."

"That ridge The bones have already made me earn a lot." Dr. Schultz patted Xiang Shan on the shoulder: "And, you also saved my town. I really have to thank you."

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

Doctor Schultz did not invite any more. He quickly found the parts Xiang Shan needed, and lent Xiang Shan a professional biological tissue surgery tool.

After confirming that Xiang Shan had gone far, Schultz went upstairs.

The mayor is in a room upstairs.

"Uncle, he did not go online." Schultz looked weird: "Why do you want me to remember to invite him to go online?"

This request of Uncle Yu, Dr. Schultz I really don't understand. However, he did. Uncle is the most knowledgeable person in this town. When he was young, he used to travel north and south and knew some secrets.

"Dresden..." The mayor called Schultz's name: "You turn off the internet first."

Schultz is nodded, directly through the brain The computer interface issues an instruction to disconnect the home network.

Anyway, he usually saves network expenses like this.

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

Schultz nodded: "Indeed, but you were lucky, that official died later..."

"He was assassinated by a knight." The mayor was silent for a moment and said: "That knight is me I called..."

"What?" Schultz screamed.

Collusion with knights, this is a serious crime against Dyson's principle!

"I did not collude with the knight. I just met a knight in the wilderness and asked for help." The mayor snorted: "Your grandfather, my father once told me, Thugs like knights are actually very useful. As long as you act humble to them, they will not embarrass you. On the contrary, they will assassinate officials they think are guilty for a certain sense of evil honor-they are actually very good. To take advantage of this. This is our very important survival wisdom."

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

"That is Before... the less people who know 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 less than the standard percentage. What does he want to do with us? , We don’t know. Maybe we can only rely on the power of the knight."

Schultz immediately understood: "You mean... the mountain 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 of not connecting to the Internet casually. I spent a few days with a knight before they went online. , Must do a long time preparation." The mayor whispered: "I don’t know if Mr. Shan is a knight. However, he can indeed fight—especially after acquiring the Martial Artist prosthesis."
