In the evening, Su Yun's parents called as usual.

Every weekend night, Su Yun's mother would always call him on time to ask how he was doing and if he had enough money to spend.

But today, although it was the same as before, and the conversation had not changed at all, Su Yun always felt that something was wrong, but he couldn't say what was wrong.

After hanging up the phone, Su Yun felt that he was thinking too much, and after taking a bath, he sat on the bed and introduced aura into his body.

It's been four months, and the operation of channeling spiritual energy into the body Su Yun has become more and more proficient, and the speed is getting faster and faster.

Although the intensity of the aura was still very thin, Su Yun clearly felt that the speed at which the aura entered his body was getting faster and faster.

It was also tonight that he clearly felt that the aura floating in his body and the white light bead that gathered in the dantian had changed, from one to two.

Su Yun felt that it was very magical, and constantly introduced the aura into the body, and the aura was divided into two strands, which converged on these two white light beads.

Two hours passed, Su Yun opened his eyes, and at that moment, Su Yun felt that the whole world had become clearer.

His senses of touch, hearing, and smell all felt a noticeable improvement, and the wind blowing in through the crack in the door was blowing through his skin, mixed with a faint scent of flowers.

Su Yun walked out of the room and came to the balcony, the night seemed to swallow everything around him, only a faint trace of moonlight shone through the night.

Originally, it was impossible for him to see anything clearly in such an environment, but now, the world under the cover of the night, Su Yun had a full view.

It's about to enter January, and the night in the capital is very cold.

Su Yun was wearing pajamas, standing on the balcony, and a cold wind blew through, which made his original sleepiness wake up a lot.

Feeling the physical changes brought to him by the second light bead, the enhancement of his five senses, and the inexhaustible physical strength, there was an indescribable feeling.

After returning to the bed and doing fifty sets of sit-ups, one hundred in a group, Su Yun felt slightly tired and fell asleep unconsciously.

The next day, December 31st.

The last day of December, Monday, tomorrow is New Year's Day.

Although tomorrow is New Year's Day, classes on Monday will continue as usual.

In the morning, it was still a morning jog, and then class, and Su Yun felt that he had returned to the familiar rhythm of life.

When I entered the classroom, the first thing that caught my eye was Li Qiqi, who was sitting in the first row, and a group of girls around her.

The classroom became quiet for a moment, and everyone turned their eyes to Su Yun, who opened the door.

Then a group of people swarmed over and surrounded Su Yun.

"Su Yun, I didn't expect you to be so powerful!

"Su Yun, Su Yun, how did you learn to sing, teach us!"

"Su Yun, what is the relationship between you and the queen Feng Yajun?"

"Su Yun, do you know the queen of heaven?

"Su Yun, can you sign it for me!"

"Su Yun... Su Yun ....."

"Su Yun ......"

Because it is an art department, most of Su Yun's class are girls, and most of the people who come up are also girls.

Su Yun was a little dazed and a little confused.

Didn't I just participate in a show and win a championship, how did I become my little fan brother and little fan sister?

But to help someone sign his name, Su Yun was not slow at all, picked up the pen and self handed to him by others, and wrote his name in a hurry, and signed more than ten in a row, Su Yun felt quite enjoyable.

Surrounded by everyone, Su Yun returned to his seat.

When passing by Li Qiqi, the two looked at each other and smiled and nodded.

Back in his seat, Zhu Yongxin rushed over and said with a smile: "How is it?

Su Yun thought about it and nodded, although there was no misunderstanding, but it should be regarded as something unraveled, right?

The day's classes were over quickly, and Su Yun packed up his things and prepared to go back to the dormitory.

Tomorrow is New Year's Day, a holiday, and everyone is discussing where to play tomorrow.

At this time, Zhu Yongxin came over and asked, "Tomorrow New Year's Day, I made an appointment with a few people and are going to go out to play, how about it, do you want to go?"

Su Yun thought about it, it seemed that his parents, who were going to come to see him, couldn't come because of something temporary, so he really didn't have anything to do tomorrow.

So Su Yun nodded: "Okay, call me when you go tomorrow." ”

"Okay, see you tomorrow. Zhu Yongxin packed up his things and went back to the dormitory.

Su Yun didn't go back to the library directly, but went directly to the principal's office, because the principal sent him a text message asking him to go after school.

Coming to the principal's office by car, Zhang Jianguo was sitting at his desk looking at the documents.

Seeing Su Yun coming, he put down the document and said with a smile: "Su Yun, come and sit down." ”

Su Yun nodded and sat down on the sofa next to him: "Headmaster, what are you looking for me?"

Zhang Jianguo personally poured a cup of tea, put it in front of Su Yun's table, and then sat on the sofa next to him, and said with a smile:

"Hehe, that's the case, next semester, our school has an event, I don't know if you are interested in participating?"

Su Yun asked, "What activity?"

Zhang Jianguo didn't answer, but asked with a smile: "Su Yun, how are you doing math calculations?"

Su Yun was a little curious and asked, "What is mathematical quick calculation?"

Zhang Jianguo took out a booklet and handed it to Su Yun, who opened it and looked at it, and the whole body was a math problem.

These questions are difficult, not difficult, they are simple addition, subtraction, multiplication and division operations, and everyone can do them.

It's not simple, but it's not easy, because he has too many digits, such as eight digits multiplied by seven digits, thirteen digits divided by ten digits, and so on.

Su Yun looked at these questions, and looked at the principal in confusion.

Zhang Jianguo explained: "This activity is called the strongest brain, and it is also a variety show. But it's different from all other variety shows, and the math problems in this booklet are one of the challenges, called math quick calculations.

You can't use computers or any other aids, you need to mentally calculate and then write the final answer on the answer sheet. ”

Su Yun nodded, looked around, and was about to find a pen, Zhang Jianguo immediately took it from his desk and handed it to him.

Su Yun picked up the pen and looked at it from the first question.

"49812 x 4621 =?" Without thinking, Su Yun wrote directly in the back: 231081252.

Zhang Jianguo's hand drinking water on the side stopped in mid-air.

"5762362035÷384157469 =?" again did not hesitate and wrote directly: 15.

“（64946+3564）x7346=503274460 ”

“142503516÷35625879=4 ”

“........”

“.......”

After a whole page, Su Yun did not stop for a moment, writing from the beginning to the last question.

Zhang Jianguo: "......@!@#@^@#"

Su Yun turned his head to look at Zhang Jianguo: "I think.... Think of this as a challenge... It's true... Is that okay?"

Zhang Jianguo: "............."

Although Zhang Jianguo had been mentally prepared for a long time, he was still shocked beyond measure.

Although the strongest brain is a variety show, for Peking University, this show is quite important.

If the contestants are Peking University students and can get a good ranking, this is quite a big publicity, and this is a great weapon to compete for students with those famous schools in Tsinghua University in the future!

Otherwise, he would not have come to ask Su Yun, after all, it was a nail, and he could have less contact, but he still wanted to have less contact.

And before he came, he also consulted an expert in mathematical quick calculations, which is why he came to this set of pamphlets.

The expert patted his chest and said: "You can rest assured, if ordinary people want to finish this page, it is impossible for him to complete the computer without half an hour! Even if he is the world mental arithmetic champion in the country today, this page will take at least ten minutes!"

Zhang Jianguo now just wants to move his head over and let him take a good look, why did this person finish writing in less than three minutes?

After all, he didn't doubt what his old friend expert said.

That can only show that this Su Yun's mental arithmetic ability is terrifying to a certain extent.

But it's only been less than three minutes, isn't it at least ten minutes for the world champion in mental arithmetic? That's more than three times faster than the world champion in mental arithmetic?

Zhang Jianguo shuddered.

At the same time, Zhang Jianguo was a little excited, if Su Yun could participate in this competition, wouldn't this mental arithmetic champion be in the bag of Peking University?

Zhang Jianguo said with a smile: "Since you have no problem with these questions, then you must have no problem participating in this show, how about it, do you want to consider participating?"

Su Yun thought for a while and asked, "Does this show have high ratings?"

Zhang Jianguo seemed to know that he would ask this, and said: "Gao! It's not at all a grade higher than the show "I Am the King of Singers" you participated in. ”

Su Yun nodded: "Okay, when?"

Zhang Jianguo: "It's probably at the beginning of the next semester, that is, in February and March, and I will inform you of the specific time." ”

"Okay, is there anything else going on? I'll go back first. Su Yun stood up.

Zhang Jianguo said: "It's nothing, you go back, I'll let you know when the time comes." ”

Su Yun nodded and went back to the library.

As soon as Su Yun left, Zhang Jianguo immediately dialed a phone call, and the phone rang twice and was connected.

There was laughter from the other side: "Hahahahaha, how is it, Lao Zhang, your classmate didn't scold you, right?"

Zhang Jianguo sneered: "You didn't scold me, he didn't arrive in three minutes, even if he finished a page." ”

"You're farting!" roared on the other side: "If anyone can finish a page in three minutes, I can eat that book." ”

Zhang Jianguo smiled: "This is what you said, you are talking about it!"
