Volume 1: Student Life Chapter 101 If you have the spare time, learn more.

"Host, please put the collection of wrong questions back into your backpack to complete the final upgrade."
Another system notification tone.
Following the system's instructions, Chen Zhou collected the wrong questions and put them into his backpack.
Then, Chen Zhou glanced at Yang Yiyi beside him, who was immersed in her own world of study.
After taking another look around, Chen Zhou leaned forward slightly, supported his chin with his hand, closed his eyes, and looked like he was in deep thought.
Consciousness then entered the system space.
There is a new message on the display.
Chen Zhou took a look and the general idea was that he still needed to explore the functions of the upgraded wrong question collection on his own.
Chen Zhou, who was already used to the stupid operation of the system, didn't really care about it.
He reached out and clicked on the backpack pattern to open the system backpack.
After carefully observing the collection of wrong questions lying there quietly, Chen Zhou felt that there seemed to be no changes in this book?
He reached out and touched the collection of wrong questions, and a line of text appeared on the collection.
"Wrong Question Collection (uniqueness): Automatically record all the mistakes made by the host in the current study."
Looking at this explanation, Chen Zhou was slightly stunned.
How should we understand the difference of one word?
What can be called mistakes in learning?
Chen Zhou frowned and thought for a while. He thought of many possibilities, but none of them were certain.
The only thing he could be sure of was that the record of wrong questions should still have the same function as before.
Anyway, after spending more than half a year, Chen Zhou finally succeeded in upgrading his collection of wrong questions, and he was in a pretty good mood.
After taking a glance at the remaining 29 cans of mental medicine, Chen Zhou exited the system space.
Sit up straight and take the collection of wrong answers out of your backpack.
I don’t know if it’s Chen Zhou’s illusion, but the collection of wrong questions seems to have a heavier feeling.
But when he compared it carefully, it didn't seem to have gained any weight.
Moreover, when he opened the collection of wrong questions, the contents recorded in it were still the same as before, without any change.
Without thinking any more, Chen Zhou raised his head, took a sip of the mental potion, and threw himself into the battle against the collection of wrong questions again.
He planned to review all his wrong questions thoroughly before starting to study the next textbook.
Time passed quietly, and before I knew it, the sky outside the library had darkened.
Chen Zhou felt someone touching him.
Tilting his head slightly, he found that Yang Yiyi was looking at him.
Yang Yiyi pointed at his watch. Chen Zhou looked down and saw that it was already 6:30 in the afternoon.
At this time, his stomach also made protesting sounds.
Hearing this voice, Yang Yiyi covered her mouth and tried not to laugh out loud.
Chen Zhou glanced at her awkwardly and murmured in a low voice: "It seems that it's not enough for me to just look at you and be full, I have to feed you as well."
As he spoke, Chen Zhou began to organize the books and materials.
Yang Yiyi handed the Calculus 1 textbook to Chen Zhou: "I have finished reading this. Please give me Calculus 2 and Advanced Algebra Volume 1 tonight."
Chen Zhou took the textbook and nodded: "I'll bring you the two volumes of Mathematics and Calculus and the upper and lower volumes of Advanced Algebra tonight."
Yang Yiyi said in surprise: "Ah? So many?"
Chen Zhou looked at her and said softly, "It's okay. I'll watch it with you slowly."
After a pause, Chen Zhou continued, "Mathematics is the most basic thing, and it will be of great help to your future physics studies. Yiyi, while ensuring your own course studies, learn more if you have the spare time."
Hearing this, Yang Yiyi looked at Chen Zhou and nodded slightly.
After Chen Zhou packed his things and carried his backpack, the two walked out of the library together and headed towards the school cafeteria.
After finishing his dinner in the school cafeteria, Chen Zhou returned to the dormitory, packed up the last two volumes of mathematics and calculus and the upper and lower volumes of advanced algebra textbooks, and stuffed them into his backpack along with his own draft paper notes.
These are all prepared for Yang Yiyi.
Zhao Qiqi asked, "Going to the library again?"
Chen Zhou: "Yeah, are you going?"
Zhao Qiqi immediately shook her head: "No, I'm afraid the light bulb is too bright!"
"Uh..." After Zhao Qiqi's reminder, Chen Zhou remembered something and asked, "Qiqi, do you want a girlfriend?"
Zhao Qiqi quickly stood up, walked to Chen Zhou, and held Chen Zhou's hand: "Yes, yes, yes, tell me where your girlfriend is?"
Seeing Zhao Qiqi 's appearance, Chen Zhou instantly regretted it. He hadn't been in the School of Mathematics for too long. How could it become like this?
Besides, having a girlfriend means you can learn from each other and supervise each other, right?
"I'll ask for you tonight." Chen Zhou broke free from Zhao Qiqi's hands, left the dormitory after saying a few words.
Zhao Qiqi's voice came from behind: "Brother Chen, my happiness for four years of college is in the hands of you and sister-in-law~"
Hearing this voice, Chen Zhou felt goosebumps all over his body.
Chen Zhou arrived downstairs of Yang Yiyi's dormitory and waited for a while before Yang Yiyi came down.
Chen Zhou took Yang Yiyi's hand and they walked towards the library.
On the way, Chen Zhou told Yang Yiyi again about introducing his girlfriend, and also described Zhao Qiqi's performance just now.
After hearing this, Yang Yiyi couldn't help but laugh.
However, she was not optimistic about introducing Li Jing to Zhao Qiqi.
After thinking for a while, Yang Yiyi said, "How about we have a social gathering between our two dormitories, so that they can get to know each other better and make their own choices."
Chen Zhou nodded: "Well, there are three singles in our dormitory, and there are three singles in your dormitory. But, our math department has taken all the cabbages from your physics department, isn't that a bad idea?"
"What do you think?" Yang Yiyi asked with a smile.
After looking at Yang Yiyi, Chen Zhou also laughed.
The two of them chatted and laughed as they walked to the library.
After finding his old seat and sitting down, Chen Zhou had not yet had time to take out his calculus and advanced algebra textbooks when Yang Yiyi handed him three textbooks.
"Here, this is for you."
Chen Zhou looked at Yang Yiyi strangely: "What is this? Thermodynamics? Electromagnetism? Mathematical physics methods?"
Yang Yiyi said, "I'm showing it to you. Physics and mathematics are inseparable. While ensuring that you study your own courses, learn more if you have the energy. By the way, return the mechanics book to me as soon as you finish reading it. I have to review it again. The midterm exam is coming soon."
"Okay..." Chen Zhou took the textbook handed over by Yang Yiyi. Although he wanted to refute, he couldn't find a reason.
Chen Zhou put these textbooks aside, took out the calculus and advanced algebra books he had prepared for Yang Yiyi and his draft paper notes, and handed them to Yang Yiyi.
Yang Yiyi took it and curled her lips.
When she opened the textbook, she was slightly stunned, and immediately flipped through a few more pages. There were annotations made by Chen Zhou on each page.
The corners of Yang Yiyi's mouth rose slightly. This boyfriend is quite considerate.
Chen Zhou had been paying attention to Yang Yiyi's expression. When he saw this smile, he rubbed Yang Yiyi's head.
It turned out that in order to make it easier for Yang Yiyi to read and help her learn, Chen Zhou distinguished the difficult points in these textbooks and also marked some knowledge points that were difficult to understand.
Withdrawing his gaze, Chen Zhou also prepared to start his own study.
At this moment, his cell phone vibrated and there was a new message.
Sender: Professor Wu Xiping.
Chen Zhou tapped the screen with his finger and clicked on the message.
"Chen Zhou, come to the seminar room we had last time. We are going to have a discussion on the topic."
