"Hey, look, Brother Chen is actually asleep?!"

Zhao Qiqi dragged Li Li and Zhu Mingli beside him in disbelief.

Li Li and Zhu Mingli turned their heads to look at it at the same time, and saw that Chen Zhou was supporting his chin with his hands, his eyes were closed, and it was indeed as if he was asleep.

Li Li turned his head with an expression that was even more surprised than Zhao Qiqi, he couldn't believe his eyes.

It's been more than half a year, and this is the first time he has seen Chen Zhou fall asleep at his desk.

It's like a myth......

Although Zhu Mingli was surprised, he said: "During this time, Chen Zhou stayed up late every day, and it was estimated that he was too tired. ”

Li Li and Zhao Qiqi nodded, and the two of them said at the same time: "Then let's be quiet, don't wake him up, let him sleep more......"

As he spoke, Chen Zhou opened his eyes, yawned deliberately, then stretched, and asked suspiciously, "Who did you just say would let you sleep more?"

Zhao Qiqi said: "We saw that you were asleep, so we said don't disturb you, let you sleep more, I didn't expect you to wake up so soon." ”

Chen Zhou rubbed his eyes and said softly, "Uh, I should have slept for a long time, right?"

Zhu Mingli replied: "It didn't take long, from the time we found out to the time you woke up, it was less than ten minutes. ”

Li Li glanced at Chen Zhou and said with concern: "Do you want to lie down on the bed for a while?"

Chen Zhou shook his head and said it didn't matter.

Zhao Qiqi and the three of them didn't say much, they each turned around and continued their own business.

Chen Zhou glanced at the three of them, and from the reactions and words of the three of them, Chen Zhou probably knew that when his consciousness entered the system space, he would be the same as falling asleep, and he would not produce other changes on the outside.

Knowing this, Chen Zhou was also more relieved.

After all, the system was still too mysterious for him, and there were so many things he didn't understand.

In the evening, after eating with Yang Yiyi, they walked around the nameless lake of Yanda, and Chen Zhou and the two went to the library.

From Yang Yiyi's "Optics" textbook, which was only to be learned in the sophomore year of the Department of Physics, Chen Zhou first glanced at the time, and then began to brush the book.

As Chen Zhou guessed, he was now completely out of the situation of using psychotropic potions, and he quickly entered immersion mode.

And with the level bonus of Physics Lv3, Chen Zhou looked at the textbook in his hand very quickly.

When he saw one of the knowledge points, he could even quickly think of several knowledge points related to it.

The connection between them will be unusually clear in Chen Zhou's mind.

And he has become more proficient when he combines the physics knowledge he has learned and applies it to problem solving.

Soon, Chen Zhou finished reading the first chapter of "Optics", "Geometric Optics".

After solving the exercises in the last section, Chen Zhou raised his hand and glanced at the time again.

"It took less than two hours?"

Chen Zhou was slightly surprised, the content of the chapter "Geometric Optics" is not a lot, there are a total of 12 subsections, nearly 100 pages of content and exercises.

If you want to say that it's all basic, forget it.

But among them, Chen Zhou feels that there are at least three places that have a certain degree of difficulty.

Thinking back to the feeling of reading the book just now, Chen Zhou only felt very happy, as if every cell was thirsting for knowledge.

And he was really immersed in it, hungry and thirsty.

The feeling of quick and clear thinking, steady and accurate writing has always been with him.

Thinking of this, Chen Zhou remembered his guess when the mathematics was upgraded from Lv1 to Lv2.

At that time, he guessed that the warm current when he upgraded was a bonus to his brain.

Now it seems that his guess at that time should have been correct.

Every time you level up, that refreshing warm current will have an additional bonus to the brain, whether it is the proficiency of knowledge, the speed of learning, or the agility of thinking, it has been strengthened......

Thinking of this, Chen Zhou smiled slightly.

By now, he finally believes that this is really a good university, so he will send the plug-in system.

Without thinking about it, Chen Zhou continued to bury his head in the textbook of "Optics".

As learning became more efficient, Chen Zhou became more and more interested in learning.

This is also the charm of learning, through the continuous acquisition of knowledge, improve yourself, can get positive and positive feedback for a long time, and can also maintain interest and freshness for a long time.

It wasn't until the closing time that Chen Zhou and Yang Yiyi returned from the state of traveling in the sea of books.

After the two walked out of the library together, Chen Zhou habitually took Yang Yiyi's hand.

After walking for a while, Chen Zhou finally remembered that there was still something he hadn't told Yang Yiyi.

He said, "Yiyi, why don't we make a good schedule?"

Hearing this, Yang Yiyi was slightly stunned, and then asked in disbelief: "Don't you plan to stay up late in the future?"

"Uh......" Chen Zhou hesitated for a moment before he said solemnly, "If necessary, I will still stay up late." But I promise, it's only occasionally. And I will ask for your consent in advance, just like this project. ”

Yang Yiyi looked at Chen Zhou, smiled, her eyes were gentle, and she nodded slowly: "Well, if it's really like this time, because of the progress of the project, and you have to stay up late, I will understand." ”

Saying that, Yang Yiyi paused before continuing: "In the future, I may also stay up late because of the topic. When the time comes, I will also communicate with you in advance and ask for your consent. ”

Chen Zhou looked at Yang Yiyi with soft eyes and nodded with a smile.

Yang Yiyi suddenly stretched out her hand and said to Chen Zhou, "Come." ”

Chen Zhou looked at her puzzled for a while: "What?"

Yang Yiyi hooked her little finger and said with a smile: "Of course it's a hook." ”

Chen Zhou smiled when he heard this, and also stretched out his little thumb to "pull the hook" with Yang Yiyi's fingers.

"Hang yourself on the hook, you can't change it for a hundred years!"

Yang Yiyi's mouth also said this well-known proverb.

After pulling the hook, Chen Zhou was about to withdraw his hand, but Yang Yiyi said again: "I still need to stamp a seal before it can fully take effect." ”

Under Yang Yiyi's instructions, Chen Zhou stretched out his thumb again and "stamped" Yang Yiyi's thumb.

"Alright, it's done!" Yang Yiyi withdrew her hand, with a hint of pleasure in her tone.

Chen Zhou smiled and rubbed Yang Yiyi's head, this girl will be intellectually like a sister for a while, and naughty like a child for a while.

Yang Yiyi glanced at Chen Zhou, pouted and said, "You are not allowed to laugh at me, this is the complete hook hanging......"

Chen Zhou's eyes were gentle, and he said softly: "That's right, this is the only way to have a sense of ceremony!"

Yang Yiyi nodded vigorously.

Looking at Yang Yiyi's appearance, Chen Zhou felt that he was lucky to meet such a girl.

After a pause, Chen Zhou said: "Then let's discuss how to cultivate good living habits." ”
