After hearing Dang Rui's words, Tang Xin said directly: "Shouldn't a man protect a woman?"
Dang Rui listened and said: "That's the old society. Now men and women are equal, and everyone holds up half of the sky. When you and I are together, don't you talk about reading ability, privacy, space, and self every day.
Then you put me on a reading pillar position again, asking me for this and that. You don’t want to be a canary in a cage, able to fly freely outside, but you also want to have a master every day.
Feeding you something to eat and drink, how can it be such a good thing?"
After hearing what Dang Rui said, Tang Xin also said angrily: "You are using strong words to make excuses. You have no ability, so you are just talking about men and women. If you can reason with women like this, you will never find a girlfriend in your life!"
After hearing what Tang Xin said, Dang Rui said to Zhan Fei: "A Fei, did you see it? She finally admitted that women are unreasonable. Of course, I'm not talking about you, Sister Wanzi, I'm talking about her.
, Unreasonable, A Fei, you must not let her get involved with this kind of woman, otherwise you will be in trouble! "
After hearing this, Tang Xin turned blue with anger and gnashed her teeth, while Qu Wanzi smiled and said: "You two like to quarrel so much, you really should get married and quarrel every day."
After hearing this, the two of them looked at each other with disdain, as if they both looked down upon each other. Zhan Fei also shook his head and smiled bitterly. These two people have a tacit understanding. Maybe they will meet next time.
When they were together, the two reconciled again!
Zhan Fei has no interest in getting between the two of them. It feels quite good to meet three old classmates from high school this time. Moreover, Zhan Fei has no original thoughts about Tang Xin at all. Instead, they were just like buddies.
The same graceful song gave Zhan Fei a thrilling feeling.
Of course, Zhan Fei is not in a hurry. After all, he has a long time to come. He will also have an extra home here in the capital in the future. He may come to visit his grandpa often in the future. There will be many opportunities in the future, so Zhan Fei said: "
I'm going to Jinghua University first, and I still have to go through training."
After hearing what Zhan Fei said, Dang Rui said: "A Fei, you are really a friend. That kind of training must be very tight. You can still come over to see us. Go back quickly and have a good rest. Don't delay it.
This is a competition!”
After hearing this, Qu Wanzi also said: "Yes, this is a very good opportunity. You must seize the opportunity and perform well. This experience will be very helpful in the future." Both of them said what should be said.
Tang Xin could only tell Zhanfei to be careful on the road, and then Zhanfei took a taxi and left Kyoto Normal University and went directly to Jinghua University.
After playing with his old classmates for a day, Zhan Fei felt a lot more relaxed, and he also decided to solve another problem and then go to his grandfather's place. By that time, his alchemy and planting skills should also be upgraded.
Then I stayed with my grandfather for a while until I finished participating in the competition in Beijing, and then returned to Bozhou University of Technology.
At that time, it happened to be close to the final exam. This time, the topic Zhan Fei chose was also one of the three major problems in mathematics in the modern world, the four-color conjecture. The four-color conjecture was proposed by a British college student.
Its content is that if some adjacent limited areas are drawn on the plane, then these areas can be dyed with four colors, so that each two adjacent areas are dyed differently. From the time when the four-color conjecture was proposed until now, it has been experienced
for more than a century.
The four-color conjecture was first proven by two mathematicians in 1976 with the help of a computer. With the popularity of computers, the mathematical community has become more accepting of computer-aided proofs, but there are still mathematicians who hope to find a simpler solution.
Or proof without the help of a computer.
Naturally, Zhan Fei wanted to challenge the computer with his own brain, to see if these forty-four points of intelligence could solve problems that other people could only prove with the help of computers.
It has been able to stump people for more than a hundred years. This question is obviously not that simple. Although Zhanfei has been exposed to a large amount of mathematical literature and professional knowledge when solving Goldbach's conjecture, however, Goldbach's conjecture is more
Most of them involve knowledge of number theory, while the four-color conjecture tends to be in the direction of topology.
Therefore, the process of solving Goldbach's conjecture did not give him any help. In the next week, he was still immersed in a sea of books as before, and by the way, before taking a break every day, he spent his energy
The value is consumed.
The days passed like this, and on the sixth day, Zhan Fei was racking his brains to think about a key issue, when suddenly a gust of wind blew over.
The informal map filled with four colors that Zhan Fei drew also fell on the ground, and then folded together, and Zhan Fei's eyes also fell on the folded four-color map.
, this scene was like a ray of light suddenly shining into his mind, and Zhan Fei's world suddenly became brighter.
With excitement and even some trembling, Zhan Fei recorded his inspiration at this moment, because he felt that this step would be an extremely important point for him to prove this proposition!
Next, Zhan Fei carefully sorted out his problem-solving process and thought about it. Soon, Zhan Fei quickly started writing. That inspiration was indeed the most critical step to solve the problem of his predecessor.
They made the most important step wrong!
The four-color conjecture was once proved by several mathematicians using methods such as reductio ad absurdum. Later, these methods were disproven to be wrong. However, this seemingly simple question is actually a problem comparable to Fermat's conjecture.
problem.
Now, Zhan Fei finally discovered that the most critical point is to prove it directly without the help of a computer. Therefore, he finally solved this problem. In eight days, it was better than Goldbach's conjecture.
It took an extra day, but immediately, Zhan Fei took a large number of drafts of his calculations and went back to his dormitory.
Today, he is going to go to his grandfather's place, because now, Zhan Fei's proficiency in planting and refining medicine has reached 99%, and he is only one step away from being able to upgrade!
Guo Shi was still training, so there was no room in the dormitory. Zhan Fei also closed his eyes. Three seconds later, the attribute panel appeared.
Next, Zhan Fei directly used today's vitality value for planting and refining medicine. Half an hour later, Zhan Fei's package once again contained hundreds of primary healing potions.
