Cyber Heroes

"What?" After leaving the scrap parts recycling bin at the east end of the town, Yuki became angry: "That old man!"

The waste parts recycling bin is actually a... thing that is more of a "public facility". If you have scrap parts that you no longer need, you can stock them here. And if anyone is short of money, you can come here and get a few parts for free.

The town will also entrust some people who have lost the ability to work to come here to maintain parts. These people have either lost their prosthetic bodies for labor and do not even have the credit to borrow money to purchase them, or their biological brain damage is so severe that it affects their ability to move.

They are responsible for storing the "barely usable" scrap iron with anti-rust oil and silicone.

However, just like Yuki's mother will store a pair of prosthetic hands for several years, a part will not be sent here until the metal fatigue is close to the limit.

But Xiangshan doesn't need any good parts.

These parts are not for his own use either. He has other uses.

But they encountered unexpected entanglements.

An old man in charge of maintenance kept saying to Xiang Shan, "You're rich," and kept holding on to Xiang Shan. This makes Xiangshan unable to select parts very well. In the end, Xiangshan had to choose a few brand-new parts from the ones he had just bought and handed them over to a few maintainers.

The maintainers left happily holding screws, diodes and other things.

"Usually, you don't need to spend money to come here for emergencies!"

"Okay, Yuki, that was originally a bit of unplanned redundancy, used as spare parts." Xiangshan stopped Yuki. He wasn't very angry. In his opinion, this is the same as "giving wedding candy when you get married". If something good happens to you (at least everyone thinks it is a good thing), it is not too much to let everyone share some joy.

It's just that the targets have changed from children to a few old men who have almost degenerated into toddlers.

The phrase "You're rich" even made him a little happy for a while.

"It seems that even in this day and age, people are still people..."

"What?" Yuki didn't understand.

"Human beings are really complicated. They are good and evil, good and bad. Sometimes I really worry that I have slept for too long and the people now are people I don't recognize...forget it. , Why am I telling you this?" Xiang Shan shook his head.

To this day, humans still show good intentions and bad intentions. That's good.

Of course, some "malice" also exists. Thinking about it carefully, Dr. Schultz's attitude in asking him to go online...could it be a test? In this era, what do people who refuse to go online mean?

But this is not a big problem.

——Of course, this does not mean that he will forgive "real malice".

"Just thinking back on my own incident, I was really shocked." Xiangshan mentioned another incident: "Yuki, do you still remember? I didn't think about coming forward at first, and someone pushed me Go out. Did you see that person? Who was standing behind me at that time?"

Even though he originally wanted to come forward, even though this matter finally got a good result, this does not mean that he will forgive the person who pushed him. This nature is different.

The person who pushed him had the idea of ​​killing him and took action.

Yuki slapped his face. Xiangshan's defeat of the warrior was so shocking that everyone forgot about it.

"I didn't see it." Yuki felt a little guilty, but there was still a bit of nervousness in his tone: "Xiangshan, what do you want to do...what do knights usually do at this time?"

"I'll tell you more about this when I get the chance." Xiang Shan patted Youki on the back: "Okay, good boy, go home now."

"Go home?" Yuki was surprised: "Where are you, Xiangshan?"

"Of course I'm going to do my thing." Xiang Shan said: "What happens next is not suitable for good children. You go home and sleep, and I will tell you the result tomorrow."

"No!" Yuki knew that Xiangshan would definitely do what the "Xia Ke" did. How could he leave at this time?

After being chased away by Xiangshan several times, Yuki was unwilling to go home. Xiang Shan finally sighed and said: "Forget it, I do plan to teach you something after all... I will take you there. But later, you have to talk less and read more. Do you understand?"

Yuki nodded excitedly, and then asked strangely: "Xiangshan, aren't you going to continue sorting out your prosthetic body?"

"No need." Xiang Shan shook his head: "Although I do want to make a prosthetic body for myself quickly, there are more important things. And this can only be done outside the town - if you want to follow, Just pick up the parts for me.”

The two people soon came to a secluded place. This was their usual road to the garbage mountain. No one would come here at night.

The moonlight is particularly bright tonight. Xiangshan adjusted the lens of his eyes and suddenly discovered something amazing.

He saw a line visible to the naked eye on the moon, which looked like a scratch on the dough. At the same time, within the halo of the moon, there was a thin line that was difficult to discern with the naked eye.

That's a very small star ring.

Something happened on the moon that caused the entire lunar landscape to change, and even a little bit of material was pulled off the lunar surface, forming a star ring with a weak sense of existence.

"I finally had the leisure to look at the moon today, and I didn't expect to see something amazing..." Xiang Shan's speaker once again failed to understand Xiang Shan's complex emotions: "I'm a little doubtful that I woke up after sleeping for many years. Or just traveled directly to a parallel world..."

Yuki sat down on the ground, and the pile of parts he carried behind him made a clanking sound: "Xiangshan, no matter what you want to do, there is no need to walk so far... I am very tired..."

Xiangshan stopped and took a look.

This location is far away from anything that looks like a signal base station and away from any place where a camera might be hidden.

very good.

Xiangshan silently took the used parts from Yuki: "Yuki, remember what you see next, remember it with your biological brain, and don't forget it even if you die!"

Xiangshan put the gears on the transmission shafts, and then placed several transmission shafts on the discarded brackets of some mechanical tools to form the basis of a mechanical structure. Then, the gears mesh with each other, and the transmission shafts intersect with each other.

Yuki's eyes widened: "Xiangshan Xiangshan, what is this? It looks so awesome..."

"Of course this is awesome." Xiang Shan stared at the instrument he was building intently, and the memories in his mind were constantly being recalled.

He was familiar with the structure.

"What's so great about this? Can it defeat bad guys?"

"Didn't I tell you? Pay attention." Xiang Shan scolded: "If you want to learn my skills, you must remember this."

Yuki pouted: "I don't even know what this is..."

Xiangshan stopped what he was doing for a few seconds.

The man said solemnly: "Well, remember it well. This structure is called a 'Turing machine'."

Yuki looked at Xiangshan's labor.

Xiangshan assembled those scrap parts into a simple and extremely ugly machine. It has no energy part, it is a gear structure, and friction will transfer kinetic energy from one gear to another... It even has a rocker handle as a power source.

Yuki scratched his head: "Is this... what you want me to remember?"

This thing is quite ugly and crude, not to mention that in order for the gears to complete this last operation, Xiang Shan used all the lubricants given by the old caretaker. This makes this thing look black and oily, which is particularly disgusting.

Xiangshan nodded, and then turned the rocker with his hand.

The kinetic energy transmitted by the hand changes direction and is divided through the gears, and is transmitted to the entire machine.

The sound of metal biting and colliding...

Xiang Shan murmured: "That's it."

"Xiang Shan..." Yuki pointed out something embarrassingly: "It looks a lot like scrap metal."

Xiang Shan raised his head, stared at Yuki, and said loudly: "The material it is made of is scrap iron, but its structure is not. You have to remember its name - Turing machine!"

The man's eyes fell on the machine again, and his tone became gentle: "It is the computer at the beginning of Hongmeng. It is the greatest product obtained by mankind in the process of studying mathematics, and it is also the origin of all internal strength."

"'Internal strength'?"

"All the martial arts you have heard of, including what you saw at the Paralympics, and what I used with that dog, are just external martial arts." Xiang Shan closed his eyes: "Of course, relatively, There are also 'internal techniques'."

"Outer martial arts are special tactics that are sublimated from the art of war. Internal martial arts are the product of the mutual improvement of intelligence and artificial intelligence."

"'Internal strength' was also called 'hacking technology' in ancient times. But those primitive hackers could not use their biological brains to intuitively manipulate codes and computing resources like today's knights. They had to face what is called a 'screen' 's output device, and then uses an input device called a 'keyboard' to interfere with that world - this is just a mortal level. The knight's 'inner power' is a hundred times more magical than that. But from the source, the internal power is indeed The evolution of hacking technology.”

The relationship between hacking technology and the internal strength of knights is like the first single-celled organism in the primitive ocean and the later higher organisms. Although the latter is mysterious and dazzling, it is always developed on the basis of the former.

"All internal strength is based on the power of computing machines, and all computers are derived from this great engineering structure..."

There was a hint of fanaticism in Xiangshan's tone.

Turing machine.

In 1920, David Hilbert, the greatest mathematician in the world at that time, the leader of the Göttingen School, and the proposer of the famous "Twenty-Three Questions" launched a charge towards the origin of "mathematics" . He proposed the idea of ​​"metamathematics" - that is, "mathematics that studies mathematics."

As long as you master metamathematics, you have mastered all mathematics.

The core of metamathematics is three topics - about completeness, consistency and computability.

Completeness, all mathematical problems can be proved or falsified.

Consistency, all mathematical assertions, are either true or false. There is no proof of contradiction that is both true and false.

Computability, all mathematical proofs, can be obtained through a feasible process and a finite number of operations.

As long as these three questions are answered, humans can solve all mathematical problems with machines - the "ultimate answer" to mathematics will fall into the hands of humans.

All mathematicians around the world are crazy about these three questions.

The Turing machine is an artifact that can overcome these three problems.

This is a structure full of "wisdom".

Yuki applauded. The applause was partly coping and partly sincere: "But Xiangshan, what does this have to do with what we call 'internal strength'..."

This chapter has many technical details and needs careful study. I’m sorry for the late update.
