The prisons of the Immortal League are very modern, incarceration and torture are separated, and the treatment of felonies and misdemeanors is not the same. Qin Xuan's reason for imprisoning Wang Qi was to seek sexual disturbance and fight, which were all misdemeanors. Even if Qin Xuan was already determined to curry favor with Chen Yan, he didn't dare to press Wang Qi into a felony prison in violation of the regulations.

Now Wang Qi still lives in a single room, and even has a bed, and can keep most of his personal belongings. The only thing that was taken away by the Criminal Law Department was the Kunshan Sword as a weapon.

Wang Qi looked to the other side. Ai Zhenwu was also arrested. However, compared to Wang Qi, who was unscathed, Ai Zhenwu was much more miserable. The right side of his face was swollen entirely, his right eye couldn't be opened at all, and his left eye was covered with a dark blue. The corner of his mouth was also broken, and a trail of blood remained.

"Don't look at me like this, the monkey is even worse. Ai Zhenwu pointed to the cell next door to Wang Qi. Wang Qi couldn't see that side, and only heard Hou Benli's vague scolding: "This group of ancient law cultivators is too arrogant......

Wang Qi nodded: "Indeed." ”

Ai Zhenwu sighed: "But you have Senior Brother Chen's support, they don't dare to beat you in front of Senior Brother Chen...... That Qin Xuan was really a scum, and he actually colluded with Gu Fa Xiu. ”

Wang Qi asked: "Are the four quick-forming foundations and one late-stage foundation refining body building attacking you? The four quick-forming foundation building bases are probably dead, and the leading body refining monk doesn't know if he is dead." ”

Ai Zhenwu's eyes lit up: "Senior Brother Wang, Senior Brother Chen already knows about this, when will he come out to uphold justice!"

Wang Qi thought for a while: "Let's wait for another four days or so." He is on duty one day every five days, and after his work yesterday, he should not come for a short time. ”

After Wang Qi finished speaking, he suddenly felt funny.

It seems that the other party has calculated that Chenfeng will not come forward for the time being, so he can rest assured to play this set boldly.

The main business of the monks of the Immortal League is to be researchers, but a group of researchers must always have a management system and manager when they get together, so everyone from the great power to the small cultivation of Qi has to spend a certain amount of time to maintain the operation of the Immortal League. However, disciples who are gifted in research are particularly privileged. Like Chenfeng, one day out of five days is enough, and if you apply for it, you can even be absent for a long time, but even so, the Criminal Law Department will not be short of a penny.

Looking at the two sighing beside him, Wang Qi shook his head and persuaded: "It is more important for you to treat your injuries than to complain." ”

The two sighed and used the Tianling Ridge spell to treat their injuries. Wang Qi continued to ask Zhenyanzi: "Old man, go on, what else can I do." ”

Zhen Xianzi suddenly fell silent, and then said: "The old man suddenly found that he had been with you for a long time, and his brain was also taken away by you. ”

"Uh......"

"When we were talking about how to calculate the Chen family here, did you think about how to get out?"

Wang Qi shrugged: "Wait." ”

"You...... You don't really have to wait four days, do you?"

"What else? There's no internet here...... No signal...... Even if the calculator can't connect to the Ten Thousand Immortals Fantasy Realm, is there any other communication magic weapon on the body? ”

Wang Qi was a little helpless about this. The wiFi signal of the Immortal Alliance Wanxian Fantasy Land covers Shenzhou, but the prison will not give the prisoner that kind of treatment.

I know that by entering the keyword Xuanxingguan in the search engine of the Immortal League, you can summon a free-spirited summoned beast Teacher Feng, or a special summoned beast Chenfeng in the Shenjing copy, but it is "You are not in the service area now", which is really a painful thing.

"And what are you going to do?"

"Look at the book. Wang Qi took out a mathematical monograph from the storage bag and said, "I've wasted a lot of time on those miscellaneous pieces." ”

The Foundations of General Set Theory, like the theoretical treatise of the same name on Earth, is considered the foundation of set theory, and it is also the place where mathematics began to be unified.

From Wang Qi's 21st century perspective, this book is already a bit backward. Without Hilbert's depth, without the nirvana of Gödel and Turing, this original set theory would not have the ability to explain all mathematics.

However, Wang Qi still looked at it very seriously.

Although the mathematics of the two worlds is highly similar as a whole, there are still some differences in the subtleties - for example, Wang Qi still does not fully understand how the Shenzhou monks bypassed the "golden diagonal" to construct the mathematical system. What Wang Qi is doing now is to feel the context of mathematics in this world and consolidate his foundation.

Wang Qi was so excited that he could not help himself at the thought of having the opportunity to participate in this otherworldly version of the Hilbert project. This is the fanaticism of mathematicians. In order to be able to better participate in this feast of mathematics, he must improve and improve.

"Logic is incomplete, systems are incompatible, propositions are not necessarily decidable...... But the Hilbert plan should not have failed, at least not so early. ”

- No one can drive us out of the Garden of Eden created by Cantor.

If I could throw out the compatibility of arithmetic systems before the completeness theorem...... Lead everyone to prove, or prove it myself, maybe this great leap forward in mathematics can be more durable?

Just when Wang Qi's mind was gradually immersed in the world of set theory, someone knocked on the iron door that controlled him.

Wang Qi looked a little irritable when he was interrupted to think. Seeing the strange link at the door of the cell, he said impatiently: "What? What's the matter? Who are you? Fight or what? It's not important, don't bother me. ”

The young man in brocade clothes was startled and asked tentatively, "Brother Wang?"

Eh?

Wang Qi looked at the young man in Chinese clothes and asked, "Excuse me...... Have we met?"

The young man smiled bitterly, as if he was a little afraid of Wang Qi: "Brother Wang is really a noble person, we are a ...... of the fairy courtyard."

"The Immortal Academy is a thousand people, I still have to remember them all?"

"We don't know each other......

"I've beaten a lot of people, okay, don't play dumb riddles, just say the name. ”

The young man was choked for a long time before he said, "I don't know if Brother Wang still remembers the name Du Bin?"

Wang Qi finally turned the name out of his memory: "Oh, oh, it's you!"

It seems like I cut off this flying sword for that stupid cat, right? Did I beat him again? When did it come?

Du Bin didn't know that he had become a foil for a half-demon in the memory of the other party, and said with a hearty smile: "I didn't expect to meet Brother Wang here, it's really ......"

Wang Qi looked at the other party suspiciously, and always had a feeling of "my life has passed hundreds of chapters and then the acquaintance's character has collapsed".
