Wei Gong returned home and told Cui Xiaoxiao what happened that day.

"Hehe, you really dare to agree without caring about the consequences." Cui Xiaoxiao's fingers were still turning over the [Introduction to Cultivating Immortals] in her hand, but she still didn't forget to give him a big white eye.

"What's wrong?" Wei Gong chuckled in his heart and looked at Cui Xiaoxiao nervously, "Didn't you say before that the brain structure and brain waves are all sets, could it be that you are just bragging, in fact, there was no such advanced virtual technology in your era?" ”

"Please." Cui Xiaoxiao closed the book in her hand and shook her head helplessly, "Do you know, many majors are very profound, and I am not omnipotent, it is impossible to understand everything, in general, I only know a little bit, but I'm afraid I can't meet your requirements." ”

"A little bit is fine." Emiya found a chair from the side to sit down, "You tell me what you know first, and then I'll figure it out." ”

"All I know is that there are all kinds of electrical signals in living organisms, and brain waves are one of them. Although human beings have long discovered that when the brain is active, brain waves will change at different frequencies and different wavelengths, but until the beginning of the 23rd century, human beings have not been able to accurately interpret brain signals, and after many generations of efforts, human beings have finally deciphered some of them. Later, we found out that in fact, the so-called brain waves, is one of our misunderstandings, you can compare it to a computer, when the computer is working, it relies on the fixed storage and reading and transmission of electrons in it, each electrical frequency has a unique position and signal, but we all know that because of the existence of resistance and electromagnetic effects, these signals radiate a certain amount of energy outward, only part of it is artificially encrypted and read, such as radio signals, is really meaningful, and the part that produces thermal radiation, It doesn't really make any sense. The same is true for brain waves, which sometimes only reflect how active the brain is, and have nothing to do with the signals in it. ”

When Cui Xiaoxiao said this, she deliberately sold it, picked up the orange juice from the side and took a sip in her mouth.

Ever since the last time Emiya told her that milk was something disgusting, she had given up all milky drinks.

The orange juice is sweet and sour, and Cui Xiaoxiao has to admire Xin Lang's craftsmanship.

At this time, Xin Lang, who was preparing dinner, was looking at the two people who were talking with a pair of surprised eyes, and the eggs in his hands had been beaten for almost 20 minutes.

Master is a genius in the sky, and his Winged Qin Sword, including the machine that later produced the Wing Qin Sword, as well as his casting process, all made him admire, but what happened to this 5-year-old girl?

He knew every word she said, but when it was connected, he couldn't understand it at all.

"So what?" Wei Gong waited for her to swallow the orange juice in her mouth, and hurriedly asked.

"So, like I said, the real thing is that to know the secrets of the brain, you have to understand the neural structure in it, just like a computer, you have to know where bioelectricity is stored, what structures are used for transmission, what are used for calculations, and how they are calculated and encoded."

Cui Xiaoxiao sighed and laughed when she said this, "Later, through a very special device, human beings can scan the entire micro-end structure of the human brain, and can also accurately capture the transmission and disappearance of any one of them. After more than 50 years, through the interpretation and guessing of hundreds of millions of electronic holograms, and then cracking and comparison, the mystery was gradually solved. There are hundreds of millions of neurons in the human brain, and humans can accurately stimulate some of these neurons through electronic resonance devices outside the body, and even later can be accurate to within ten digits, just like making a computer program work through encoding, and corresponding to the physical layer is stimulated by a certain electrical signal, so as to change the electrical signal in the computer. The basic principle of computers is binary, and we later discovered that the bioelectric signals in the human brain can also be converted into binary, so that we can achieve a very advanced and realistic virtual world. ”

Originally, Xin Lang was holding a learning mentality and listening to the lecture while beating eggs, but when he heard this, he already felt that he was in a fog, and he was afraid that if he continued like this, the whole person would collapse, and he would not have to cook dinner tonight.

He shook his head, then glanced at Cui Xiaoxiao, ignored them, and walked into the kitchen by himself.

As Wei Gong ordered, he pressed the switch next to him, and then on the latest invention called the [Liquefaction Furnace], he heard the slightest sound of steaming.

He turned the switch to the right again, and saw sparks coming out of the liquefaction furnace, and the flames jumped when the ground was lifted.

Compared to the topic they just talked about, the principle of this liquefaction furnace is simpler.

Xin Lang knew that there was a channel at the bottom of the stove, connected to the gas that could be burned, and when the switch was pressed, the valve would open, and then the gas would gush out.

Then rotate to the right, in fact, through the high pressure impact of the special material inside, resulting in a very strong vibration, the electric spark generated at the end of the wire, ignite the gas, so as to achieve the purpose of life and cooking.

Although he could have used the [Fire-type] technique to achieve the same, or more convenient and practical purpose than this, Xin Lang still admired his master's genius design and ingenious implementation techniques.

Ever since he had the [electricity] that Master said, every thing he made was actually invisibly gradually liberating the role of [people] in it, Xin Lang thought to himself, maybe one day, Master could become a great existence like Yue Chuanwo.

In the living room, Wei Gong's brows were furrowed, and the more he listened to Cui Xiaoxiao, the more deeply he felt the infinity of knowledge and his own ignorance.

He thought quietly for a moment, then raised his head, "So what do I need to do if I want the Heavenly Sword Emperor to see a very real virtual scene?" ”

"First of all, you need a very large map of the microstructure of the human brain, or a coding map of the human EEG signals, and secondly, you need a super quantum computer, which can achieve super artificial intelligence, because you have to use it to simulate the human brain and send information accurately, and we have to have an EEG scanner and a consciousness converter, which is to make the electrical signals in the brain encode and transmit them regularly through external stimulation."

Cui Xiaoxiao said this, and she didn't want to continue to communicate with Wei Gong, "However, I don't understand any of this, or at least I have to give me more than twenty years to study one or two, so you still have to die of this heart." ”

Wei Gong's face turned iron-blue, this damn girl, if I can't solve the problem of the Dream Sword Emperor, it will be a crime of bullying!

There was no way, he looked through the system in his brain, and felt that he could only rely on the so-called [Dream Sword].
