"Your foundation is poor. Pen, fun, pavilion www. biquge。 info" Reading the test papers, Chen Xin said sincerely.

Nodding his head without shame, there was a hint of hope in his eyes.

"It's a heavy task, and in less than thirty days, you need to start all over again." Chen Xin put down the test paper, looked at it and said, "Don't go back these days, I will talk to the teacher in the library and leave you a bed." ”

Nodding harder than to make up his mind, Chen Xin got up and wandered among the bookshelves, and when he came back, he had an extra cart in his hand, and the cart was full of heavy books.

"These books help shape your problem-solving thinking, and I'll be back in ten days to check on your reading." After finishing speaking, Chen Xin patted the ash on his sleeve and walked away.

Looking at the cold book case, he didn't have the desire to open it at all, but for now, he only chose to believe in Chen Xin, after all, this was his only hope for being admitted to the department.

Chen Xin went to the old professor's office, which was the same as on weekdays, the old professor was reading the newspaper and drinking tea, and his four brothers were reading quietly.

"I'm curious about what kind of person impresses Wei Wei." The old professor's eyes were slightly raised, and the gold-rimmed frame drooped down.

"He's very calm, he looks older than his real age, and he's very cautious in his dealings with people, but he doesn't see anything commendable about it. Of course, that article was really well written. Chen Xin replied.

The old professor was silent, and Chen Xin said curiously, "You have reached a consensus with Teacher Wei?" ”

"Yes, let's each take a step back, and as long as he can pass the assessment, I will accept him as a closed disciple." The old professor said calmly.

Chen Xin was a little surprised, and before he could speak, someone said, "Teacher, if he is not qualified, our senior brothers will not recognize him." ”

The old professor said with a smile, "Thirty days to be admitted to the headquarters from scratch, if he does it, coupled with the vision of economic excellence, I think he does have this qualification." ”

Chen Xin bowed his head and was silent, guessing that he was sweating profusely when he read in the library, and suddenly he wanted to laugh out loud.

It's been three years, and I'm finally going to have a junior brother again.

This conversation is not known to the time in the library. He held an English translation of "Treatise on Logic and Philosophy", and pondered it but could not understand it. It's full of specious and mystical things, such as the question: There are three gods with names that are "true", "hypocritical", and "arbitrary", but you don't know which god has what the name is. "Truth" always tells the truth, "hypocrisy" always tells lies, and whether what "arbitrarily" says is true or false is completely random. Now, you need to identify the real names of these three gods and can only ask "yes"/"no" questions 3 times, each for one deity (but you can ask the same question to multiple deities). The gods can understand what you say, but they will only answer your questions in their own language. In their language, there are da, ja, but you don't know which is "yes" and which is "no".

After reading it, he didn't stay on the paper to write and draw for a long time, and after half an hour, his eyes lit up and he had an answer.

First ask question x to God 1, which can be such that as long as God 1 is not arbitrary, then if God 2 is arbitrary, then God 1 answers ja, otherwise answers da. After asking x, if the answer is ja, then we can be sure that God 3 is not arbitrary. If the answer is da, we can be sure that God2 is not arbitrary. Assuming that God 3 is not arbitrary, then we ask God 3 question y, which can be such that if God 1 is arbitrary then answer ja, otherwise answer da. After asking y, we can determine who is arbitrary, 1 and 2. Then we ask God 3 question Z, which can be such that if God 3 is true then answer ja, otherwise answer da. In this way, we can determine the names of 1, 2, and 3.

Write the answer, check it again, make sure there are no logical loopholes, and read on.

Thinking is a time-consuming thing, and before you know it, it's already dark outside, but you don't wait to be like a demon, holding the book motionless. After a long time, a female teacher came over and interrupted the thoughts.

"Classmate, the lights are going out." The female teacher called.

Don't wait to get out of the state of thinking, look at the book in your arms, and feel a little unwilling.

"Over the years, there have been a lot of great talents in the library, they all know the word "restraint", don't be greedy for wine, and the same is true for reading, you have opened the door to a new world, it's normal to be excited, but don't get carried away. ”

When the female teacher's words woke up in time, he got up and bowed respectfully to the female teacher, put away the books and went to sleep in the lounge on the top floor of the library.

After waiting for a while, Chen Xin appeared behind the bookshelf, his small body like a ghost in the middle of the night.

The female teacher took the "Treatise on Logic and Philosophy" that she had not read for a while, looked at the notes on the paper in the book, and couldn't help but sigh, "If this child could have come here earlier, he would have been a malleable talent." ”

"It's not too late." After Chen Xin finished speaking, he turned around and said respectfully, "I will bother the teacher in the future." ”

"If you can help, you can help." The female teacher nodded.

Chen Xin thanked him again, then stopped talking, sat on the bookshelf and took a book casually and read it silently. Since Chen Xin first came to the library, he has been like this night and night all these years, he doesn't care what books he reads, or even the content of his reading, he just reads, he practices a state of reading.

The lights in the library were dark, and an oil lamp beside him was dimly lit.

After 12 o'clock, the library must be closed, as is the rule. But once there are rules, there will definitely be people who break the rules, such as reading at night, which is the privilege of learning idiots.

Probably accustomed to this scene, the female teacher didn't see it, and after inspecting to make sure that no one was staying, she locked the door of the library.

In the lounge on the top floor of the library, I don't have to wait to sleep with a pillow in my arms. For him, today is a day of great significance, when the book is read through, his sense of accomplishment is no less than hitting a superb piece of equipment, and the equipment will always be exhausted one day, but the long sea of books is inexhaustible.

At five o'clock the next day, without waiting to wake up, he turned over, found new toiletries in the cabinet, and after doing a good job of personal cleaning, he went straight to the reading room. Although it was still early, there were already many people in the reading room, so I didn't wait to find a quiet place to continue reading the unfinished "Treatise on Logic and Philosophy".

At eight o'clock, the female teacher came over, put a loaf of bread and a glass of milk on the table, and knocked on the table. didn't wait for a moment, looked at the female teacher for a while before reacting, smiled in a low voice and said, "Thank you." ”

At noon, after reading "Treatise on Logic and Philosophy", the next book is "Practical Common Sense of Life".
