In the blink of an eye, three years have passed.

Ji Zhen has been in this world for four years.

"It's time to leave, my plans in this world have been overfulfilled."

When he first came to this world, Ji Zhen's plan was very simple, that is, to learn martial arts, and he didn't want to make a big career.

In this world, it is to lay a good foundation for martial arts.

And this plan, he has already overfulfilled. He has already learned Shen Rong's palm and knife techniques, and even Wang Zhenwei's Wang family's marksmanship.

And the reason why marksmanship can be learned is because of Shen Feiyan's help. Because the current Shen Feiyan is already Wang Zhenwei's wife.

Knife technique, spear technique, and palm technique, Ji Zhen used a [Ninefold Refining Realm Tower] derivation technique, and fused it into a set of palm techniques of his own.

General's Order!

Because the name is domineering, Ji Zhen took this name. With an order, all armies fight!

It is as fast as the wind, as slow as a forest, as plundering as fire, as immobile as a mountain, as difficult as its yin, and as moving as thunder!

The six mysteries entrust Ji Zhen's expectations for the general's order. When he truly integrates these six mysteries into his own palms, then the general order can be called the general order!

As for the pure yang energy, he already has Shen Rong's sixty percent of the heat, and his physical fitness is more than three times that of ordinary people.

Shen Rong came to Ji Zhen's side, "Are you leaving?" ”

Ji Zhen nodded, "I've lived with you for four years, and now that I've learned martial arts, it's time to go out and travel around the rivers and lakes." ”

Shen Rong was silent for a long time before he said, "You must come back safely." ”

Ji Zhen nodded, "Don't worry, I won't joke with my life." ”

"Your self-created general order that combines sword, marksmanship, and palm skills is very good, and I can see that you have high expectations for it, and I hope you can go your own way."

"But there's one thing you're missing."

"What?" Ji Zhen asked curiously.

"Murderous, bloody!" Shen Rong said, "The real masters all came out of stepping on other people's bones. ”

After saying this, Shen Rong walked out of Ji Zhen's room.

"Murderous, bloody!" Ji Zhen muttered for a while, and he didn't know what to think in his heart.

After a moment, Ji Zhen shook his head and shook off the thoughts in his mind.

Pinch the seal with both hands.

Break!

The Boundary Breaking Technique was launched, and Ji Zhen's figure disappeared into the Admiral's Mansion and disappeared into this world.

···

"It's finally back!"

Back in the dormitory of Yenching University in the urban society, Ji Zhen looked at the time, and only an hour had passed.

"It's a good thing that the time is out of sync."

I put away my ancient clothes, cut off my long hair, and changed into a modern urban outfit.

Yanjing has entered November, and the temperature is already very low.

"Fortunately, it's this time, otherwise the muscle changes in my body would have been seen by Lin Fei!"

Thinking of Xu Linfei, Ji Zhen suddenly felt a warmth in his heart, this girl had firmly occupied his heart, and no one else could get in anymore.

In the four years that he has been in the world, Ji Zhen has never been to the land of Fireworks Willow Lane, because he has always had Xu Linfei in his heart.

Even if Shen Feiyan was a little fond of him, Ji Zhen chose to turn a blind eye, and finally fulfilled Wang Zhenwei.

Without him, there is already someone in his heart. Moreover, he couldn't give Shen Feiyan happiness.

I like a person who doesn't need to be in charge, but marriage is in charge.

It seems that with the return to the world of urban society, the four years of Xu Linfei's four years have surged up in an instant.

This longing almost controlled all of Ji Zhen's thoughts, giving him an urge to go to her immediately.

But Ji Zhen pressed down, he first took a bath, and then in the bedroom, he corrected his language and behavior in the mirror.

After all, after living in the ancient world for four years, some things have become habitual.

"It seems that we have to rent a house as soon as possible, and it is a bit inconvenient to rent a house in this dormitory. In other words, we should plan for the future of our city. ”

This urban society is equivalent to his main world, and there is also his confidante. Therefore, it is also necessary to have a life plan here.

"This [Ninefold Refining Realm Tower] actually doesn't have storage space. If there is, just take something out of the ancient world. ”

For the planning of urban life, Ji Zhen actually already has an idea. In the ancient world, Ji Zhen also occasionally thought about this problem.

In the end, Ji Zhen returned to the original point, the original dream of this body, to be a teacher.

Being a teacher is free and has long vacations. Of course, if it is an ordinary teacher, it will definitely not be in line with Ji Zhen's thoughts.

Because he has an unusual girlfriend. And to be worthy of this girlfriend, without revealing his secrets, ordinary teachers will definitely not be able to.

So, he plans to be a professor, and he is a professor at Yenching University.

In this way, as a professor at Yenching University, there is naturally no problem. With fame and strength, of course, it is not difficult to make money.

And how to become a professor at Yenching University, Ji Xin also has some ideas. He accepted all the knowledge of mathematics and physics from his predecessors, and then focused on both.

"This urban society also has the world's seven major mathematical problems. However, the Poincaré conjecture was not solved! This is a good opportunity for me, otherwise, I will have to use the deduction technique of the [Ninefold Refining Realm Tower]. ”

In his previous life, between November 2002 and July 2003, the Russian mathematician Grigory Perelman published three preprints of papers claiming to prove the geometric conjecture.

After Perelman, two groups of researchers published papers to complete the missing details in Perelman's proof. This includes Bruce Kleiner and John Lott of the University of Michigan; John Morgan of Columbia University and Tian Gang of the Massachusetts Institute of Technology.

In August 2006, the 25th International Congress of Mathematicians awarded the Perelman Fields Medal. The mathematical community finally confirmed that Perelman's proof solved the Poincaré conjecture.

On June 3, 2006, Professor Zhu Xiping and Cao Huaidong of Sun Yat-sen University published a paper of more than 300 pages in the June issue of the Asian Journal of Mathematics published in the United States in the form of a special issue, which filled the loophole in Perelman's proof and gave a complete proof of Poincaré's conjecture.

And this Poincaré conjecture happened to be in contact with Ji Zhen in his previous life. Because at that time, he was looking up information because he was writing a novel and read it.

All the papers are more than 300 pages, and of course Ji Zhen at that time just swept them aside, read a rough idea, and couldn't understand many things.

However, now that Ji Zhen has mathematical knowledge, it is another matter, and the difficulty is to completely eat it thoroughly.

"It seems that my memory has become obscure, and I still remember the papers I read in a flash in my previous life. This should be the ability brought by the [Ninefold Refining Tower]. ”

Although there is such a plan, it is not a simple project, and it takes a lot of time and effort.

"Fortunately, as long as the direction and theory of verification are good, then the process of verification can still be made up by computer."
