"Ask the host to return the error set to their backpack to complete the final upgrade. ”

Another system beep.

Chen Zhou followed the prompts of the system, collected the wrong questions, and put them in his backpack.

Then, Chen Zhou glanced at Yang Yiyi beside him, who was immersed in her own learning world.

Glancing around again, Chen Zhou leaned forward slightly, supported his chin with his hand, closed his eyes, and made a contemplative gesture.

Consciousness then enters the system space.

There is a new prompt message on the display.

Chen Zhou glanced at it, which roughly meant that the upgraded function of the problem set still needed to be explored by himself.

Chen Zhou, who is accustomed to systematic sand sculpture operations, doesn't care much about this.

He reached out and clicked on the backpack pattern to open the system backpack.

After carefully observing the set of mistakes lying quietly, Chen Zhou felt that this book didn't seem to have changed at all?

He reached out and touched the error book, and a line of text appeared on the wrong book.

"Error Set (Uniqueness): Automatically records all errors in the host's current learning. ”

Looking at this explanation, Chen Zhou was slightly stunned.

How to understand the difference between 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 can be sure of is that the record of the wrong question should still function the same as the original.

Anyway, it took more than half a year for Chen Zhou to finally upgrade the wrong problem set, and his mood was still quite good.

Glancing at the remaining 29 cans of spirit elixir, Chen Zhou withdrew from the system space.

Sit up straight and take the problem book back out of your backpack.

I don't know if it's Chen Zhou's illusion, but the wrong question set seems to have a sense of heaviness.

But when he compares it carefully, it doesn't seem to have gotten any heavier.

Moreover, when he opened the wrong question book, the content recorded in it was still the same as before, without the slightest change.

Without thinking about it anymore, Chen Zhou raised his head and drank a sip of the spiritual elixir, and once again threw himself into the confrontation of the wrong question set.

He is going to completely sort out the wrong problem set before starting to study the next textbook.

Time passed quietly, and before you knew it, the sky outside the library had darkened.

Chen Zhou felt someone touch him.

Tilting his head slightly, he found that Yang Yiyi was looking at him.

Yang Yiyi pointed to his watch, and Chen Zhou looked down, it was already half past six in the afternoon.

At this time, the sound of protest also came from his stomach.

Hearing this voice, Yang Yiyi covered her mouth and tried not to laugh.

Chen Zhou glanced at her a little embarrassed, and muttered in a low voice: "It seems that it's not enough for me to be full, I have to feed you too." ”

As he spoke, Chen Zhou began to sort out the books and materials.

Yang Yiyi handed the textbook of Score 1 to Chen Zhou: "I've finished reading this, you can bring me the Score 2 and Gao Dai volume in the evening." ”

Chen Zhou took the textbook and nodded: "In the evening, I'll bring you the last two volumes and the upper and lower volumes of the Gao Dynasty." ”

Yang Yiyi was surprised and said, "Huh?

Chen Zhou looked at him and said softly, "It's okay, I'll accompany you to watch slowly." ”

After a pause, Chen Zhou said: "Mathematics is the most basic thing, which will also be of great help to your future physics studies." Yiyi, while ensuring that you learn your own courses, you can learn more if you have spare energy. ”

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 dinner in the school cafeteria, Chen Zhou returned to the dormitory, packed up the textbooks of the last two volumes and the upper and lower volumes of Gao Dai, and stuffed them into his backpack along with his draft paper notes.

These are all prepared for Yang Yiyi.

Zhao Qiqi asked, "Go to the library again?"

Chen Zhou: "Yes, are you going?"

Zhao Qiqi immediately shook his head: "Don't go, I'm afraid the light bulb is too bright!"

"Uh..." After Zhao Qiqi's reminder, Chen Zhou remembered one thing, so he asked, "Qiqi, do you want a girlfriend?"

Zhao Qiqi hurriedly got up, walked to Chen Zhou's side, and held Chen Zhou's hand: "If you want it, you can tell me where your girlfriend is?"

Seeing Zhao Qiqi's appearance, Chen Zhou instantly regretted it, he didn't stay in the courtyard for too long?

Besides, having a girlfriend is not just learning from each other and supervising each other?

"I'll ask you in the evening. Chen Zhou broke free of Zhao Qiqi's hands, dropped a word, and left the dormitory.

Zhao Qiqi's voice came from behind him: "Brother Chen, four years of college, my happiness depends on you and my sister-in-law~"

Hearing this voice, Chen Zhou felt goosebumps rise.

Coming to the downstairs of Yang Yiyi's dormitory, Chen Zhou waited for a while before Yang Yiyi came down.

Chen Zhou took Yang Yiyi's hand, and the two walked towards the library.

On the way, Chen Zhou told Yang Yiyi about introducing his girlfriend again, and by the way, he also described Zhao Qiqi's performance just now.

When Yang Yiyi heard it, she couldn't help laughing.

However, she was not optimistic about introducing Li Jing to Zhao Qiqi.

After thinking about it, Yang Yiyi said again: "Otherwise, let's have a friendship between the two dormitories, let them get acquainted with each other, and it is better to choose by themselves." ”

Chen Zhou nodded: "Well, it just so happens that there are three singles in our dormitory, and there are also three singles in your dormitory." It's just that our number of courtyards have arched all the cabbage in your courtyard, wouldn't it be good?"

"What do you think?" Yang Yiyi asked with a smile.

Glancing at Yang Yiyi, Chen Zhou also laughed.

The two of them talked and laughed like this, and walked to the library.

Finding the old position and sitting down, Chen Zhou didn't have time to take out the textbooks of Shufen and Gao Dai, but Yang Yiyi handed over three textbooks.

"Now, for you. ”

Chen Zhou looked at Yang Yiyi strangely: "What is this? Thermal, electromagnetic, mathematical and physical methods?"

Yang Yiyi said: "For you, physics and mathematics are not separated." While making sure you learn your own courses, learn more if you have the spare time. By the way, that mechanics, you can return it to me after reading it, I still have to comb it again, and the mid-term exam season is due soon. ”

"Okay..."Chen Zhou took the textbook handed over by Yang Yiyi, although he wanted to refute it, but he couldn't find a reason.

Chen Zhou put these textbooks aside first, took out the number of points and Gao Dai and his draft paper notes prepared for Yang Yiyi, and handed them to Yang Yiyi.

Yang Yiyi took it and pursed her lips.

Flipping through the textbook, she was slightly stunned, and immediately turned a few more pages, each page with Chen Zhou's marking.

The corners of Yang Yiyi's mouth slightly hooked a range, this boyfriend is quite intimate.

Chen Zhou had been paying attention to Yang Yiyi's expression, and when he saw this smile, he touched Yang Yiyi's head dotingly.

It turned out that in order for Yang Yiyi to read more smoothly and help her study, Chen Zhou distinguished the difficult points in these textbooks, and also marked some knowledge points that were difficult to understand.

Retracting his gaze, Chen Zhou was also ready to start his own study.

At this time, his phone vibrated and there was a new message.

Sender: Professor Wu Xiping.

Chen Zhou's finger touched the screen and clicked on the message.

"Chen Zhou, when we came to the seminar room last time, we planned to have a topic discussion. ”
