Wang Jian was familiar with the prison visit process, and waited patiently for almost noon, seeing that it was about to be his turn, a police officer came over and took him to a separate meeting room, with a metal table and two chairs in the middle.

"Master." It was as if I was seeing a loved one, and I was finally able to reach out and touch it.

Fang Ziming was relieved by a master's call, and pretended to be angry: "Buy so many things, you want to support me?" ”

"It's a holiday." Wang Jian forced a smile and looked very reluctant, turned his face and asked Officer Liu, "How is it arranged here?" ”

Officer Liu had no expression behind his back, waited for Fang Ziming to sit down on the opposite face, took out the application form with a red stamp in front of Wang Jian, handed it over, and said, "Old Fang, it is about Xiao Jian's future, you can read carefully." ”

"......" Wang Jian.

"Let him make up his own mind." Fang Ziming saw from the beginning to the end, with the signature of the top leader of the North Sichuan Prison on it, knowing that this matter was not trivial, and he was not Wang Jian's immediate family, how could he dare to make decisions without permission.

Wang Jian didn't know why, so he hurriedly took his eyes, and didn't show joy for a while, not only "Discrete Mathematics", but also "Linear Algebra", "Calculus", "Probability Theory", and even "Integrated Circuits", "Information Engineering", "Network Information and Security" and other professional courses.

The wish exceeded expectations, and he hurriedly asked Officer Liu for a pen, Fang Ziming reminded: "Xiao Jian, read the following content clearly." ”

"Hey~ I don't believe that the prison can still ask me for tuition." In a minute, Wang Jian's face collapsed, and a line of small bold characters below read: From the date of completion of the study, all technical behaviors of the student shall not endanger national interests and security, and accept the relevant tasks assigned by the state at any time for a period of ten years, and after ten years, the relevant units will be properly resettled.

In addition, if the student uses the technology he has learned to endanger national interests and security, once investigated, the student and the referee will be subject to relevant legal sanctions.

"Damn, there is really no free cooking cake in the world!" Wang Jian regretted: "I shouldn't have mentioned this matter today." ”

"You can say no." To tell the truth, Officer Liu can't eat Wang Jian's temperament, but if he goes out of line, he, the recommender, will be jointly and severally liable, of course, if the rabbit cub performs well, he will also be stained, and risks and glory coexist.

As far as the current situation is concerned, Wang Jian can't refuse, there is a military order against Feng Lei in WeChat, Yang Kun is still waiting for him to make trouble in the Heavenly Palace, and it must be completed before the end of this month, in other words, Wang Jian forced himself into a dead end, which is the end of relying on good memory and overconfidence.

"Officer Liu, if I want to sign, won't I become a civil servant?"

"You want to be beautiful." Officer Liu poured cold water and said, "The above didn't say that you would be paid, let alone your rank and position." ”

"And what am I? Tricksters? ”

"It's a metaphor."

"......" Wang Jian.

"But you can rest assured, with your IQ, it will take a year and a half to complete all the courses, and it is estimated that there will be no tasks in two or three years."

"Shall I learn?"

"Hehe~~" Officer Liu rarely appreciated a smile today: "If you can't learn, don't go to the crematorium, I will personally pay for your entire stall." ”

"Holy!"

Obviously angry, Officer Liu handed over an ink pen, and after Wang Jian finished signing, he signed his name: Liu Zekan.

Visiting a prison can put himself in, Wang Jian is also the first person in ancient and modern times, the time is tight and the task is heavy, Officer Liu didn't eat lunch, he personally arranged the study matters, and the course started after the meal.

Here I have to mention the political commissar, on the highest floor of the prison administrative building, a separate classroom was appointed, and the teacher was naturally Professor Ye Chengkui, the old man heard that he gave a lecture to a gangster who had not finished high school, and a hundred did not agree, worried that no one would save him from a high blood pressure attack, and when he heard that he could smoke, he immediately agreed.

When Old Man Ye walked into the classroom and saw a familiar face baring his teeth at him, he realized that he was Fang Ziming's criminal, and his heart suddenly fell, and he decided to smoke a cigarette to suppress his fright in order to relieve his excitement.

Teaching others is to seize the opportunity to smoke, and teaching Wang Jian is different, the rabbit cub thief is a thief, but when the real one-on-one teaching began, Old Man Ye gradually became surprised, he learned too fast, it can be described as a speed of progress, and the first chapter passed in less than an afternoon.

But Wang Jian still shook his head, this kind of purely academic, or purely for the purpose of preparing for the exam was not what he wanted, and took advantage of the break to help Old Man Ye light a cigarette: "Old Ye, can you tell me more about the purpose of "Discrete Mathematics"?" And the most basic logic? ”

"Huh~~~~ It seems that your kid is a pragmatist, so you came prepared, right?"

"I'm teaching myself crawler technology, and I need this as a foundation."

"It's the right way, okay."

The time is approaching in the afternoon, and the physical condition of the old man Ye will naturally not be too late, Wang Jian carried the computer on one shoulder, helped the old man downstairs to eat in the cafeteria, and went to bed next door to the classroom at night, turned on the computer and continued to study crawlers.

Due to the special situation, Lao Yetou's morning exercise was exempted, he got up early to drink two bowls of millet porridge in the canteen, and then received a box of cigarettes in the designated office.

The teaching is completely detached from the book, from the practical point of view from the shallow to the deep, from the initial concept formation to the development of "Discrete Mathematics", inside and out, Wang Jian closed his eyes and devoted himself wholeheartedly, and his intuition told him that it was almost time, and it was still so close to being lost.

"Xiaojian, the underlying logic of the action of the crawler technology is to sample data such as discrete point collections and graphs, through points, rings, groups, domains, lattices and Boolean algebras, and finally summarize and layer to form a data collection, which is the principle of Baidu's search engine."

Hearing this, Wang Jian opened his eyes, looked outside, and it was almost noon, and said, "Old man, why don't you go and have a meal first, I'll read a book." ”

"Okay, I'll smoke a cigarette and go."

Lao Ye lit a cigarette and went around to Wang Jian's back, seeing that this kid was reading a book, he was completely flipping a book, a page of content was no more than twenty seconds at most, and he laughed from time to time, Lao Ye could hear it, and the laughter was full of excitement.

After smoking a cigarette, Old Man Ye casually made a question on the whiteboard, clapped his hands and said, "Solve it, old man, I will count you as the completion of "Discrete Mathematics". ”

Wang Jian looked up when he heard the sound, took the blue oil paint pen and knocked on the door of his head to write, maybe he had just mastered it and was still very rusty, and he wiped it twice halfway, and finally came up with an abstract formula.

"Hmm~~ Although some are not very skilled, it should be almost the same if you play with crawlers." Old man Ye nodded and praised, "You kid should be a scientist." ”

"Oh, I said old man, don't let them hear what you say." Wang Jian almost covered the old man's mouth, if Liu Zekan heard it, he might secretly change ten years to twenty years.
