My destiny is to go to work in a world that is collapsing

Hua Yi told Ai Yin some things about himself with some reservations, which naturally aroused her curiosity.

"So, do you really still have the identity of a psychiatrist?"

"Well, because I have been practicing for a long enough time, you can consider me an expert in this field."

"expert? Is there anything special about you compared with ordinary practitioners?"

"Experts will analyze the patient's pain and treat the patient's pain, but will not experience the other person's pain personally, otherwise it will bring a burden to themselves - this is the description of the relevant books, but in my definition, expert has another meaning , anyway, it is more powerful."

Looking at Hua Yi's rather contented look, Ai Yin wanted to refute that a girl who was given the upper hand by the other party at the beginning of their meeting would often think about turning defeat into victory.

However, when it came to areas that she did not understand, she did I don’t have much capital to refute.

So I have to come up with what I’m good at.

"Find two tetrahedrons with the same base area and height that cannot be divided into two sets of corresponding congruent tetrahedrons……"

Hua Yi looked at a math problem and muttered to himself.

This is Hilbert's third problem, one of the"23 most important contemporary mathematical problems" proposed at an international mathematical conference.

Although this question was answered in the second year, this should not be something that children of Ai Yin's age should be exposed to.

It really deserves to be Ai Yin.

Hua Yi, who had accumulated considerable knowledge during this period, knew the answer, but did not point it out immediately.

He has already seen Ai Yin's mentality at the moment.

Hua Yi decided to grant her little wish temporarily.

And Ai Yin, who had been staring at Hua Yi's performance, had an excited look on her face at this moment.

"I feel like you won't make any progress even if you read it a dozen times."

Since meeting Hua Yi, a person with whom she has a common language, Ai Yin has become much more lively.

"So, have you already thought of the answer?"

"……I'm thinking"

"Sure enough, it’s better to just look at the answer."

Hua Yi's words made Ai Yin startled.

"Eh?!"

"Nothing bad. We are here to explore the unknown, not in an intellectual contest. Since predecessors have already found the answer to the question, as long as it is verified to be correct, there is no need to deliberately throw the answer aside and explore it yourself."

"But……"

Ai Yin clenched her fists unwillingly.

Such obvious competitiveness made Hua Yi rub her head, making her hair, which had not been combed properly, even more messy.

"Everyone's imagination has its limits. Only by learning to use the imagination of others can we see higher and further. Otherwise, we will always start from the very beginning, and how far can we go?"

"……"

"Well, the book says that you can define an invariant based on the side length and dihedral angle of the polyhedron."

"What? Let me see it quickly!"

Jing Ruo is as active as a virgin.

Ai Yin, who was still thinking silently, jumped up from her seat because of Hua Yi's words, and couldn't wait to snatch the book in his hand.

If Hua Yi hadn't reacted quickly enough, he let go in time. Hands, this mathematics book will be torn by love.

Only people who are truly passionate about knowledge will show such an eager attitude.

Look at the mathematical palace described in the book as if you are fascinated by it. Ai Yin, Hua Yi said

"I've prepared dinner for you. See you tomorrow."

Hua Yi's words made Ai Yin raise her head fiercely, subconsciously trying to retain her, and opened her mouth but no words came out. The smart Ai Yin had already realized that with Hua Yi's level of knowledge, only Being a tutor is actually a sign of humiliation.

Although the mother who devotes most of her energy to work earns a good salary, after deducting living expenses, even if all the remaining salary is used as Huayi's compensation, It’s not too generous.

Hua Yi has given Ai Yin help in life and study, allowing her to see a new path and a new world, and has been leading her forward so far.

Of course Ai Yin is grateful, She also understands that the other party is not the type who is greedy for money.

However, she will not take up Hua Yi's remaining time because of her personal emotions.

"Well, be careful on the road"

"Has the little one learned to care about others? It deserves praise. Don't worry, even though I live some distance from here, I won't encounter any danger."

Ai Yin kept watching Hua Yi's back completely disappear from sight. She just returned home and locked the door. She wanted to completely immerse her mind in the ocean of knowledge again, but failed for a while.

She knew that, Hua Yi lives quite far away from the city.

Although the war has ended, there are many official announcements that clearly state that residents should try to avoid setting foot in the wilderness far away from the city, emphasizing this behavior with little concealment. Dangerous.

Ai Yin sometimes worried that Hua Yi would be in danger.

If it weren't for Hua Yi's feelings about the place where he lived, Ai Yin would have preferred that he could live in this city directly.

After thinking about it for a long time, Ai Yin just withdrew her attention and put it on the book in her hand.

From a purely mathematical perspective, Ai Yin knew that her reading time had been reduced.

Originally, her daily life, apart from eating and sleeping, consisted of reading. After Hua Yi appeared, Ai Yin divided a large portion of her reading time into talking to Hua Yi.

Sometimes it was for intellectual discussions, and sometimes it was just a simple chat.

Even, because she always It was Hua Yi who was embarrassed to cook. Ai Yin, who originally lacked interest in things other than knowledge, spent some extra energy studying cooking skills.

Unfortunately, so far, Ai Yin's level is still limited to making bread jam. Although it is not a dark dish like simple flour soup, it is far inferior to Hua Yi and cannot be used.

Although she no longer has a lot of time to read as before, Ai Yin feels that she is progressing faster. That’s it.

You get twice the result with half the effort, which makes you happy.
