Gong Suhe then said, "when did it fall to me?"

Zhai Xingchen had an idea: "yesterday morning."

"Oh, I asked for leave yesterday morning," Gong Suhe said

Zhai Xingchen was relieved and afraid of killing the chat, so he asked, "what are you doing?"

Gongsuhe only when the other party is a classmate, so: "mathematics."

She may be in a bad mood today, and now she is sleepy, so she wants to find something to distract her energy.

So, she took a picture of the paper in an abnormal way: "it's done here."

As soon as Zhai Xingchen looked at it, he found that the steps in front of the problem Gong Suhe did were a little complicated.

So he took the drafting paper, wrote a few steps, and then photographed Gong Suhe: "is this better?"

Gong Suhe enlarged the photo, first looked at the steps, and then his eyes brightened.

She immediately replied: "really, I didn't expect this method at all. Thank you. What's your name?"

Zhai Xingchen was flustered when he saw this.

When he thought of what he said on the Internet, he didn't want to answer it, so he pretended not to see what Gong Suhe asked. Instead, he wrote another question on the paper and sent it to Gong Suhe: "this question can also be asked in the same way."

Gong Suhe thought that the other party would come to pick up his pen tomorrow, so he didn't worry about the name. Instead, he went to see the question from Zhai Xingchen.

It seems that this question is not the same type as the one just now, but strangely, it can be used in the same way.

So she took the straw and wrote down the steps.

Zhai Xingchen received Gong Suhe's photo and raised his lips: "well, right."

Gong Suhe replied: "thank you for teaching me a method."

She thought about it carefully. There are only a few students who are good at math in school. Li Chengyi, Lu Yuze and a girl in class two.

Li Chengyi is definitely not. She has Li Chengyi's wechat.

Lu Yuze... Gong Suhe doesn't believe the other party will do this.

Is it the girl?

She shakes the idea in the heart, discovers the other party has sent the message to her again.

"Look at this question." Zhai Xingchen had a ghost in his heart and didn't dare to continue to speak mathematics. So he sent an English question to him: "I don't know much about it. Can you tell me how to understand it?"

Gong Suhe saw that it was a reading comprehension, which was a bit complicated. She read it carefully, and then chose the answer: "is it acbbd?"

Zhai Xingchen replied: "yes, I can't do the third question."

Gong Suhe looked at it, and then found that the typing explanation was more complicated, so he made a speech directly.

When Zhai Xingchen received the news, he did not expect that it was voice.

He opened it carefully. For the first time, he didn't even think about what Gong Suhe was saying. Until he played it again, he followed the question. Then, over and over again, he began to understand

Then he replied, "I see. Thank you."

Gong Suhe replied: "you're welcome. Reciprocity. If I can't do math, can I ask you? "

Zhai Xingchen immediately replied: "good."

After the reply, he felt monotonous and didn't feel serious enough, so he added, "no problem."

Gong Suhe finished the last question and was really sleepy, so he said, "I'm going to clean up and wash. Good night."

"Good night." Zhai Xingchen said.

He can't sleep. There are several unfinished tasks in his previous private work.

Moreover, he is also working on a mathematical model. Now it has a prototype and needs to be constructed slowly.

That night, Zhai Xingchen fell asleep with his mobile phone in his arms, relaxed and smiling.
