"In the past two days, I have tried to finish reading the sixth volume of "The Principles of Armament Design and Production", and then I can ask Ji Lao to borrow the unique book of armaments to read."

After all, I am going to participate in the National Youth Weapons Knowledge Competition, if I can master a little more knowledge, then it must be helpful to myself, and the only book of weapons, the reason why it can be called a single book, the main reason is because it is the only one in the world.

Due to its age, the paper cannot withstand repeated re-reading, so there are very few survivors, and every book that exists in the world today is of great significance for research.

Generally speaking, such books with archaeological and research value are handed over to the state, and of course there are some antique dealers who buy them as souvenirs, and it is clear that Ji Yan should belong to the latter.

An afternoon was short and happy.

Beauty is companionship, books are fun, such a time, simple and warm, although the two still don't have much intersection, but Gong Ning still likes this feeling very much.

Because he promised that Tong Guang would guide him at night, after dinner in the evening, Gong Ning went directly to the club, after all, his studio had secrets, so Gong Ning made an appointment in the exchange area in the hall.

Gong Ning went straight to the communication area, and soon found Tong Guangzheng looking around while reading a book.

"Master, you're here." Tong Guang's voice looked very happy and whispered hello.

Gong Ning nodded a little unnaturally, coughed pretending to be old-fashioned, and then sat upright, looked at him like a master, and said, "If you have any doubts, you can ask me now." ”

"Well, I've brought my little notebook with me." Tong Guang said and took out a small notebook from his bag, turned the third page, put it in front of Gong Ning, and said, "Master, I haven't been very clear about this issue, can you tell me about it?" ”

Gong Ning picked up the notebook and looked at it.

"If the echo texture of the dolphin is applied to the communication device, can it play a role in delayed communication?"

Seeing this question, Gong Ning was instantly suffocated, to be precise, this is not a problem, but a conjecture.

Although he doesn't know Tong Guang very well, through this question, Gong Ning can obviously feel that he is not a dull student, because his thoughts jump a lot, if you have to use one word to describe it, it should be inferences.

That's right, this is a guy who likes to draw inferences, and the reason why he can come up with such a tricky conjecture must come from his usual thinking.

He loves to learn, loves to think, and has talent, if he can't become a martial arts master in the future, Gong Ning himself doesn't believe it.

"Yes, there is potential to be my disciple......" Gong Ning nodded contentedly, feeling a little proud of such an apprentice.

After all, his thinking itself is too avant-garde, and he is afraid that he will not understand what he tells him, but now that he knows that he is also a person who likes to think crankily, Gong Ning suddenly has a feeling of finding the same kind.

"Actually, I've thought about this question before, and I've experimented with it, but have you ever thought about a question, what is the purpose of our delayed communication? It's nothing more than the fear that the receiver won't receive it at the first time, so the purpose of the delay is to play a short-term storage role, thereby increasing the time period for the spread of information, but this storage is very unstable, and it is not permanent, so I think there is no point in conducting in-depth research on this, do you know what the current human society lacks? It is the material of memory, and once we humans have found materials and textures that have a storage function, then it will change the history of our entire human ......"

Gong Ning talked endlessly about some science and technology on the earth, Tong Guang listened to it with taste, his eyes lit up, and he even took the initiative to ask questions at the end, which Gong Ning was even more impressed by him.

Throughout the night, Tong Guang was basically asking, Gong Ning was answering, and the two chatted happily.

Soon, it was 10 p.m.

"You should have a class tomorrow, so that's all for today, and we'll come back tomorrow night." Gong Ning stood up with a smile.

"Well, thank you, Master." Tong Guang stood up with a resolute face, bowed seriously, and thanked him.

Gong Ning shook his head a little amusedly, and said, "I'm not a few years older than you, so you don't need to give me such a standard courtesy." ”

"Let's go, it's so late, I'll send you home." Gong Ning smiled and led the way ahead.

"No, Master, I'll just go back by myself." Standing on the deserted street, Tong Guang's figure looked a little thin.

"I know you live in a shantytown, let's go, I'll send you back." Gong Ning said lightly.

Hearing the three words shantytown, Tong Guang was in a trance for a moment, and after a while, his eyes nodded a little evasively.

The so-called shantytown is actually a place used by the government to help those orphans and the disabled, as well as some lonely and widowed elderly people, and the government will distribute fixed food and clothing every month, which Gong Ning can see from the clothes on his body.

And because these orphans are not left alone, their education is free.

However, because of their living environment and their natural position as a sponsored disadvantaged group, such people often have low self-esteem and are often bullied both in school and in society.

These things, Gong Ning's memory is all there.

The disadvantaged group, this name, Gong Ning actually thinks it is not very accurate, maybe materially they are poor, but spiritually, Gong Ning feels that they have an advantage that others do not have, that is, their strong survival ability and the reverse quotient to resist setbacks.

After all, they have not been hungry since they were children, and living in such an environment, how much frustration and ridicule they receive, how strong their hearts will grow.

None of these advantages are available to the rich kids.

Therefore, Gong Ning did not discriminate against them.

After all, he is from a science background, and nothing can be judged entirely by subjective consciousness, everything should be considered, measured, and judged from a scientific perspective.

Soon, the two came to the shanty town.

Looking at most of the alleys that were already dark, Gong Ning could imagine how extravagant the crystal nucleus was in this area, and they didn't dare to turn on the lights most nights without financial resources.

"I'll send you here first." Gong Ning knew that he was not suitable to go in, and said with a smile.

"Well, thank you, Master." Tong Guang still insisted on bowing as always.

Gong Ning waved his hand, a little helpless, he understood the other party's behavior, after all, he was used to being a human being, and when he encountered an opportunity to change his fate, he would not give up, nor would he dare to slack off.

This is a knot, a knot that has been planted for thousands of years, too ingrained to untie, not for a while.
