After a meal, Chen Zhou chose a classic original picture to replace the sand sculpture photo.

Looking at the four squares gathered, he couldn't help but sigh that this computer background is not much stronger than that...

Touching the phone, Chen Zhou opened the chat with Yang Yiyi, and sent her a [Black Question Mark ❓ Face .jpg].

Soon, Yang Yiyi replied with a smile covering her mouth.

Chen Zhou's fingers flew, and a series of question marks were thrown over again.

After waiting for a while, Yang Yiyi replied to the message.

A series of pictures.

Chen Zhou clicked and swiped to view.

It was the fireworks of Anhui Agricultural University after the college entrance examination.

The photo set as the background by Yang Yiyi is also here.

Chen Zhou looked at it and suddenly laughed.

Although the people who took that photo were a little confused, they still looked scared away.

But sandwiched between these photos, it suddenly feels good.

Before Chen Zhou finished reading, his mobile phone rang again, and there was new news.

Chen Zhou quit the movie mode, and saw a message from Yang Yiyi.

[I know you from Huang Jiayi's mouth, I know you from the study of Maochang High School, and I know you from every day's small luck. The snowflakes of that Christmas, the two Kong Ming lanterns with the same words written on them, the fireworks that dazzle behind you. 】

[This you, saved my unhappiness. 】

After Chen Zhou finished reading it, he didn't know how to get back, he rubbed for a long time, and replied [I saved your unhappiness, then I will be your happiness in the future].

"Ahhh It's too... Yahhhh I actually said something like this..."

Chen Zhou turned over his phone and put it on the desk, he didn't know what message Yang Yiyi would reply, and he couldn't say how he was feeling now.

There was another prompt sound of new news on the mobile phone, Chen Zhou glanced at the mobile phone that was buckled behind his back, wanting to see it but not daring to look at the news that Yang Yiyi had returned.

After hesitating for two seconds, Chen Zhou made a quick move, picked up the phone, unlocked it, opened the chat software, and glanced at the message that Yang Yiyi replied.

[Happy, it's time to sleep.] If you stay up late again and I know about it, I'll beat you up. 】

"I'll go..."Chen Zhou suddenly realized at this moment, did he find a girlfriend with violent tendencies?

After replying to the message, Chen Zhou got up and took the basin to wash.

It's almost time to wash up and go to bed...

Early the next morning, Chen Zhou was woken up by an alarm clock.

Glance at the time, 7:30.

Because today is Saturday, Chen Zhou set the alarm clock a little late.

He got up and went to wash, and then he was ready to go to breakfast.

Breakfast needs to be eaten before eight o'clock, otherwise there is no sense of ceremony.

When Chen Zhou was about to walk out of the dormitory, Zhao Qiqi's voice came from behind him: "Brother Chen, bring two buns and a tea egg..."

After that, Zhu Mingli's voice said: "I want multigrain pancakes and soy milk..."

Chen Zhou simply stopped and looked at the last person.

Li Li sat up from the bed, put on his glasses, and scratched his head: "Chen Zhou, I'm sorry for you, bring me a bowl of porridge and egg cakes." ”

“OK。 ”

Chen Zhou gestured to Li Li and went out.

Downstairs in the dormitory, Yang Yiyi was already waiting for him.

Seeing Chen Zhou, Yang Yiyi took the initiative to step forward, stared at Chen Zhou and asked, "Did you sleep well last night?"

Chen Zhou paused and yawned untimely.

He hurriedly explained: "I slept with you last night, I didn't stay up late!"

Yang Yiyi suddenly laughed.

At breakfast, Chen Zhou thought of Li Li's plan to participate in the competition, so he asked, "Yiyi, Li Li wants to participate in the competition, is there any lack of teammates in your academy?"

"Is that the IMO gold medalist in your dorm room?"

Chen Zhou nodded.

Yang Yiyi thought for a while and said, "Li Jing hasn't formed a team yet, I'll talk to her when I go back." ”

Chen Zhou: "Then you ask, I have news to tell me." ”

Yang Yiyi: "Don't worry, if this girl knows that there is such a powerful god, she will definitely be happy." ”

After breakfast, Chen Zhou returned to the dormitory with the "takeaway" ordered by Zhao Qiqi and the three of them.

As soon as I sat down, Yang Yiyi's news came, and Li Li's matter had been settled.

Chen Zhou replied with a grateful expression, and then told Li Li the news, and by the way, he also said that the other party was a girl, so take advantage of it.

Hearing Chen Zhou's words, Zhao Qiqi and Zhu Mingli glanced at each other, and instantly felt that they had missed a whole world...

Chen Zhou in the morning finally had time to be busy with his own affairs.

Without the phone harassment of Wu Xiping and Zhang Zhongyuan, he walked quietly at his own pace.

I used the new computer to download the materials sent by Wu Xiping and solve the content of the project he was responsible for.

Because of Shen Jing's experience, Chen Zhou only started to write after carefully examining the information.

No mistakes are guaranteed to waste time.

Moreover, Chen Zhou obviously felt that he was more proficient in using the mathematical knowledge he was already familiar with.

When reviewing the corresponding knowledge points, the memory also becomes clearer.

In general, it is quick and clear thinking, and the writing is steady and accurate.

When he solved the problem at Shen Jing's last night, he vaguely felt this way, but he didn't have a deep experience.

Now, as the task is solved, this feeling is even more obvious.

Chen Zhou guessed that this was the role of mathematics to reach Lv2.

Recalling the warm current when he was upgraded, it should be a bonus to his brain.

The human brain is the most wonderful thing, and some say that the brain represents everything about a person.

If a person's body dies but his brain is not dead, it is possible for him to be reborn.

Of course, Chen Zhou doesn't believe in these, he believes that the "development" of human beings on their own brains is positive.

This development does not refer to how much the brain has developed, as is often referred to in the ordinary sense.

After all, there has long been a scientific explanation that the human brain has been fully utilized, and there is no such thing as 100% exploitation.

Human brain cells are 100% active every day.

As for why some people are very smart and some people are very stupid.

This question has long been answered.

This is mainly related to the activity of the areas of the brain that are responsible for different functions.

Chen Zhou estimated that the principle of the psychotropic drug was the same, but it was not as real as the system upgrade.

"I don't know, what kind of experience is it to arrive at Lv3?"

But thinking of the 2000 years of experience that was still missing, Chen Zhou let go of his blind thoughts.

After all, the task of the system is to require him to complete a research project independently, but now he is not fully ready.

Looking at the textbooks he had brought back from the counselor, there were still a lot of leftovers, which he urgently needed to finish in the future.

Retracting his thoughts, the pen in Chen Zhou's hand became active again, and he re-immersed himself in the world of solving problems.

The time was close to noon, and Chen Zhou was woken up by Shen Jing's call.

"Hey, senior?"

"Chen Zhou, you're right. ”
