She breathed a sigh of relief, put down her schoolbag, touched her phone, and sent a WeChat message to Chen Yaya.

Ying Xi: [Yaya, when you come here later, please bring me some breakfast, and I didn’t have time to buy it.] Ying Xi: [Thank you~]

Chen Yaya probably hasn't woken up yet.

No reply yet.

She was not in a hurry, mute her phone, stuffed it into her schoolbag, and then turned on the high-major book.

This semester, there are three courses that are difficult to pass.

One is high mathematics, the second is big things, and the third is C language programming, and they are all high-credit subjects.

Ying Xi actually has no big goal for getting scholarships with high grade points. She just wants to avoid failing the subject and get these more than ten credits.

But the subject is too difficult.

It is really a challenge for someone like her who is just average in science.

Ying Xi took a deep breath.

Calm down and focus on the topic.

"Suppose the function f(x) continuously... can be deduced...try to prove... so that..."

She bit her pen.

Unconsciously frowned.

It took a long time to write down tremblingly: [Proof: Ask…]

Then what?

Then there was no idea.

What is the future and what imagination, at this moment, seems to be completely defeated by this series of strange mathematical symbols, which only makes people feel depressed.

Chen Yaya hasn't come yet.

Ying Xi raised her head and unconsciously walked around the library self-study area, trying to find a savior.

Suddenly.

Meet a familiar face.

Zhu Wei pushed open the glass door and was yawning, walking towards her.

Ying Xi still thought it was his own illusion, thinking that he just happened to pass by this area.

Unexpectedly, the boy actually pulled the stool and sat opposite her.

It was obviously coming to her.

Zhu Wei had a very large circle of black shadows under his eyes, as if he hadn't slept all night, and he looked very haggard.

Another yawn.

Then he barely supported his strength, lowered his voice, and called her: "Sister-in-law... Oh no, junior Ying Xi. Good morning."

Ying Xi: "?"

Zhu Wei took out a cup of soy milk from his bag and put it in front of her.

"Have you had breakfast? I just came from the cafeteria and made an extra drink. Please drink it."

Ying Xi frowned, "...Why?"

Zhu Wei: "There is no such thing as this? It's just that I just met you. I just don't meet you in this place. By the way, I'll sit here for a while and I'll be a thank you for taking up a seat. Junior sister, don't dislike me."

"But I still have classmates to come."

Zhu Wei waved his hand, "It won't take long, I'll go to class later."

Ying Xi was still full of doubts.

But seeing that Zhu Wei's expression was open-minded, he was in the library and was quiet around him, so he didn't ask much.

I had to agree.

Zhu Wei didn't come to review, he just lay on the table for a while, as if he was resting.

Not long after.

After he dozed off, he rubbed his eyes and stood up.

"School sister, then I'll leave first."

Ying Xi was still fighting with advanced mathematics and couldn't be distracted, so she just nodded casually, counting as a response.

Zhu Wei wandered for a moment.

After all, I still feel that I can't speak up.

Xie Caizhou, this dog thing.

He gritted his teeth and cursed a few times.

Take out a book of exactly the same high-quality mathematics from your schoolbag and put it in front of Ying Xi.

Then, he quickly left.

The back looks like he is running for life, and he does not give any chance to refuse.

Ying Xi flipped it out casually.

The book is full of problem-solving processes, ideas, and answers.

There are also key points of the exam.

The handwriting is elegant and very familiar.

Ying Xi: “…”

The author has something to say: The first update.

I am too sleepy to finish writing the second update, so I will change it to the afternoon of the 6th!

The comments seem to be about 5,000.

Thank you very much for your support! Mua!(*╯3╰)~
Chapter completed!
