As soon as Han Feng returned to his residence, he received a call from Professor Li Zhongwen.

"Han Feng, did you leave that note on the lab table?"

"Yes. Mr. Li, you can see that equation, this is an equation I have recently obtained based on experimental data, and its solution is exactly in line with your theory of solitary wave of neural impulses. ”

Li Zhongwen said directly: "Where are you now, I'm going to look for you now!" His excited tone showed that he was quite excited at the moment.

Han Feng knew that he must have realized the importance of that equation, but it was not early yet, so he said, "I'm outside the school now, or I'll look for you tomorrow." ”

I only heard Li Zhongwen say: "I can't wait, Han Feng, where are you now, I'll go to you right away!" I'm already at the school gate now. ”

This Li Zhongwen is really an impatient. Han Feng shook his head with a smile, and had no choice but to say, "Then you wait for me at the school gate, I'll be there in ten minutes." ”

Hung up the phone, Han Feng brought all the data he had measured before, he knew that after a while, Li Zhongwen would definitely have to ask him how he got that equation, although Han Feng's information was not enough, but he couldn't manage so much, the big deal was that he was lucky, he just came up with such an equation, if he wanted to prove it strictly, let him supplement the measurement-related data by himself.

When I came to the school gate, I saw Professor Li Zhongwen pacing back and forth at the door from a distance, holding the note left by Han Feng in his hand, and stopped from time to time to take a look.

Li Zhongwen raised his eyes and saw Han Feng coming over, and hurriedly took two quick steps to come to Han Feng's face. said: "Han Feng, you are finally here! Tell me about this equation in detail, and how did you get this equation?" Han Feng's partial differential equation is too mathematically strong, although he listed the steps for solving the equation on it, Li Zhongwen still didn't understand it. However, he understood that Han Feng's equation was the mathematical proof of his neural impulse solitary wave theory.

Han Feng said: "Let's find a place first." ”

"Yes, yes. Find a place. Look at me, I'm dizzy. Li Zhongwen thought for a moment. He said, "Go to my house." It's not far from that. ”

Li Zhongwen lives in the school's teacher's apartment, in Mizuki University.

After Li Zhongwen opened the door, Li Shanshan trotted out of the back room, and said as she ran: "Dad, you're back~" She was wearing a kitchen skirt around her body at the moment, holding a spatula in her hand, like a housewife.

"Huh?" Li Shanshan was stunned when she saw Han Feng behind her father. "Han Feng?" she looked at her father with a puzzled look. Obviously, it was very strange how Han Feng came to her house at this time.

"Hello, Li Shanshan...... Schoolmate. Han Feng smiled at her. My heart was beating a little faster.

"Shanshan, you cook more for one person's meal today, and Han Feng has dinner here. Professor Li Zhongwen took off his coat and hung it on the hanger. Then he said to Han Feng, "Let's go to the study." ”

"What's the matter with Dad looking for him?" Li Shanshan thought for a while, without a clue, then she suddenly remembered that the kitchen was still cooking, exclaimed, and hurriedly ran into the kitchen.

After coming to the study, Han Feng suddenly asked, "Is Li Shanshan usually cooking?"

"Yes, I'm usually busy and don't have time to take care of her, but she usually takes care of me, hehe!" Li Zhong smelled a knowing smile, "This kid has been very sensible since he was a child." ”

Han Feng nodded thoughtfully.

"Han Feng, you don't have a girlfriend yet, do you?" Li Zhongwen suddenly asked at this time.

"Uh......" Han Feng was stunned for a moment, with an unnatural smile on his face, and said, "No...... No. ”

"Haha!" Seeing him like this, Li Zhongwen was immediately happy, "What's so embarrassing about this, people who are all in college, it's normal to find a girlfriend." ”

Han Feng touched his nose and didn't speak.

"Okay, okay, let's not talk about it. Li Zhongwen took out the slip of paper with the equation written on it in his pocket, "Now, you explain this equation to me in detail." ”

So, Han Feng explained the solution of this partial differential equation to Li Zhongwen in several ways, and then without waiting for him to ask, he told him the process and data of this equation he derived. Boiling members hit by hand

Han Feng's thinking is very clear and very organized, and he basically makes it easy to understand and simple when explaining. He came up with this equation himself, so it was not a problem to do this.

After hearing this, Li Zhong sighed: "With only such rough data, you can come up with such an equation, I don't even know what to say." Han Feng, do you know how excited I was after seeing this equation? Originally, I thought that it would take at least several years to mathematically prove the solitary wave conduction characteristics of nerve impulses, but I didn't expect you to solve this problem so easily!" Although from a rigorous scientific point of view, in order to truly prove the correctness of this equation, it is necessary to further measure more accurate data, but in Li Zhongwen's opinion, this has become manual labor. This theory of his is already supported by mathematical proofs?

"I have been researching this topic for several years, but I didn't expect that because of your participation, there will be results so quickly, Han Feng, I will definitely write your name on the front of the paper, this topic, you have made the most critical contribution!"

Han Feng hurriedly refused, saying that he didn't help much, just casually put forward some opinions, and he was very lucky to come up with such an equation on the basis of Li Zhongwen's previous research results. According to Han Feng's meaning, it is best not to even add his name to the paper, let alone add it in front. Li Zhongwen naturally refused to agree, and in the end, the two argued for a long time, and each took a step back, and Han Feng agreed to sign it, but only as one of the deputies of this research.

In front of Li Shanshan, Han Feng always felt that he couldn't face it naturally, so at the moment when his level system was about to enter operation, he excused himself with important things to do, and he quit without even eating.

After Han Feng left, Li Shanshan asked, "Dad, what are you looking for Han Feng for?"

"Han Feng, this kid, is really a genius!" Li Zhongwen sighed, and then, he told his daughter all the role and contributions that Han Feng had played in this subject during this time, and finally he said, "It is a very correct decision for me to dig him from the Department of Computer Science to our Department!"

Although Li Shanshan knew that Han Feng was very familiar with neuroscience, she never expected that Han Feng would be so powerful and could help her father a lot in his subject.

What kind of person is he? Li Shanshan now knows less and less about Han Feng.

Han Feng casually ate something outside, and after returning to his residence, he began to work on improving his "Mixed Yuan Body Technique".

He first kept repeating the newly learned Xingyi Fist, over and over again, and while punching, he entered the state of inner vision and observed the internal force in his body.

What happens when you move with your breathing? What happens when you don't?

By repeating and observing over and over again, Han Feng finally understood what Zhao Dong meant by "breathing out extraneous breathing and internal breathing".

External respiration, which mainly refers to the gas exchange between the outside air and blood that takes place in the lungs, while internal respiration, which refers to the respiration on a cellular scale, is the gas exchange between blood and tissue cells. The purpose of external respiration is to promote the progress of internal respiration, thereby stimulating the activity and potential of cells.

Although there is only such a seemingly simple link, but the impact on the cell is huge, in these two cases the "Dan flow", although their essence is the same, are nerve impulses, but the nature is relatively different, the image of a metaphor, "Dan flow" like a woman, gentle temperament like water, has a great stimulating effect on the activity of cells, and the "internal force" is a man, its sexual masculinity is rapid, the impact on the cell is more forging and strengthening, into the body of others, it has great destructive power.

According to Professor Li Zhongwen's theory, nerve impulse is a mechanical impulse, and in the final analysis, its essence is a kind of energy, and from this point of view, Zhao Dong's understanding of internal forces is quite correct.

Once you know the principle, the rest is easy to do.

Han Feng then set out to improve his "Mixed Yuan Body Technique", he streamlined his previous movements again, eliminated those actions that generated energy that was biased towards internal force, and combined with the appropriate breathing method, he finally formed a set of "Mixed Yuan Dan Flow Technique" that specialized in cultivating Dan flow. Then, according to the characteristics of the internal force, he perfected the previous movements, improved one action at a time, and strictly stipulated the timing and method of breathing and exhaling at each step, and finally formed a set of "mixed element internal force body technique" that specializes in cultivating internal force.
