Nan Zhi chattered away, completely oblivious to the fact that Shen Xingmian's face was so dark it looked like ink could be squeezed out.

With a "snap," Nan Zhi stopped. She blinked and looked at Shen Xingmian. The boy threw the high school math book aside, turned his head, and stared at Nan Zhi with a cold expression for a few seconds. Nan Zhi involuntarily swallowed. What should she do if she was a little nervous?

"I promise you what I just said, let's have a contest, using junior high school knowledge. If you lose, you have to grant me one request."

The boy's tone was flat, as if he were talking about something that had nothing to do with him.

Seeing his demeanor, Nan Zhi felt a little uneasy, as Shen Xingmian seemed quite arrogant.

But then she thought that this person hadn't paid much attention in middle school, while she was a good student in middle school. Although it had been a long time, Nanzhi felt that if he wouldn't have trouble in high school, he should have no problem in middle school.

So he agreed: "Okay, but don't regret it. Even if you lose, you have to agree to one condition."

Seeing the girl's confident expression, Shen Xingmian's eyes flickered slightly, and she nodded, "Here's the book. You can find any questions you like, I'll keep you company."

He handed the first-year junior high math book to Nanzhi, who took it. The first-year content was actually quite simple. She flipped through it and decided not to find anything too easy, so she picked the last big question at the end of a practice exercise, which was more difficult.

"For this game, whoever figures it out first wins."

Nanzhi placed the textbook in the middle and showed Shen Xingmian the math problem.

Shen Xingmian smiled slightly upon seeing this, while Nan Zhi leaned on the table and started calculating.

Shen Xingmian slowly looked at the questions, and Nan Zhi had been calculating for quite a while before he picked up his pen.

Nanzhi frowned as she calculated a problem for the first year of junior high school. She realized that her approach seemed to be wrong, so she started over. This time, her approach was correct.

Nanzhi wrote half a page of paper before finally finishing the calculation.

She looked up and saw that Shen Xingmian was still sitting there motionless, just like before. Nan Zhi was very pleased with herself. "Shen Xingmian, you lost."

Shen Xingmian chuckled, "Are you sure?"

As she spoke, she pushed her exercise book toward Nanzhi. Nanzhi glanced down at it and saw that Shen Xingmian's method was simpler than hers. She had solved the problem by writing three equations, and the answer was the same as hers.

Nanzhi: "......"

"No way? When did you do this? I didn't even see it."

Seeing her astonishment, Shen Xingmian unconsciously curved her lips into a slight smile, "While you were engrossed in calculating..."

Nanzhi: "......"

After thinking about it, Nan Zhi felt even more cheated. She waved her hand and said, "No, no, this doesn't count. Best two out of three."

Shen Xingmian raised an eyebrow. He had never seen Nan Zhi act so shamelessly before, and he found it quite novel. "Alright, you can choose the topic for the second round."

Nan Zhi decided that this time she must choose an easy one. She quickly calculated it and then beat Shen Xingmian.

Soon, Nan Zhi found a problem that suited her taste, showed it to Shen Xingmian, and said, "This one, let's begin."

After saying that, she wrote furiously, afraid that Shen Xingmian would catch up with her.

The boy sat there without moving, but his expression gradually softened.

"Wow, I won! Shen Xingmian, you didn't know how, did you? Did you?"

After Nan Zhi finished, she glanced at Shen Xingmian's blank exercise book and couldn't help but shout with joy. Shen Xingmian glanced at her and said, "There's one last question. I'll choose the question this time."

Shen Xingmian picked up the first-year junior high school textbook that was placed in front of Nanzhi and began to read it.

Finally, he randomly picked a question of moderate difficulty and said, "I won't make it too difficult for you, this one will do."

Nanzhi glanced at the question and thought it was very simple, so she said, "Hmph, you're obviously afraid of making a mistake, aren't you? You're really good at making excuses."

He looked at Shen Xingmian with disdain, then chuckled, "Shen Xingmian, you must have been trying your luck the first time. You couldn't even do such a simple calculation problem, and now you dare to say you're not making things difficult for me."

Shen Xingmian's gaze fell on her. "Think what you want."

After saying that, Nan Zhi saw Shen Xingmian looking down at the question, so she also raced against time, lest Shen Xingmian get lucky and she would lose.

Having finally won against Shen Xingmian in this matter, she couldn't let this opportunity slip away.

This time, Nan Zhi calculated even faster, and the problem was even simpler than the first one. She finished the calculation in a few seconds, while Shen Xingmian was still writing down the answer.

Nan Zhi couldn't help but laugh, "Shen Xingmian, you lost, I won, hahaha."

After saying this, Shen Xingmian put down his pen; he had finished writing.

Nan Zhi said smugly, "Even if you finish writing, you've already lost. I finished before you."

Shen Xingmian glanced at her. "Really? That's not necessarily true."

Nan Zhi: "..." The smile on her face disappeared, replaced by disdain. "Hey, seriously? You're going to cheat now that I've won?"

Shen Xingmian sighed helplessly, "How about this, let's see if there are any problems with our answers first?"

Nanzhi didn't care; she was sure she was right anyway.

So they compared answers with Shen Xingmian, and the results were different.

Nanzhi frowned immediately. "I'm sure I'm right. You've miscalculated."

Shen Xingmian remained silent, instead staring at Nan Zhi with great interest. The girl looked confident, though it was unclear where she came from.

"Why don't we check it out?"

Nan Zhi paused, then took out her phone. "Go ahead and investigate. I'll show you how treacherous the world can be."

After saying that, she took a picture of the question and uploaded it. The answer came out quickly. When Nanzhi saw the last result, her brows furrowed even more. How could this be?

She tried flipping through it, and the answers were the same.

So, she was wrong?

"So, Mu, have you given up yet?"

Shen Xingmian actually smiled in a good mood.

Nan Zhi: "..." She glared angrily at the boy, but Shen Xingmian seemed not to notice and shrugged indifferently.

After a long silence, Nanzhi gritted her teeth and said, "I'm willing to accept defeat. So, what are your conditions?"

Upon hearing this, the boy stared at her intently, then suddenly fell silent.

Just as Nanzhi was about to continue speaking, she heard him speak calmly:

"With your IQ, how did Qin Yi manage to explain it to you?"

Nan Zhi: "...You won, but why are you resorting to personal attacks?"

Shen Xingmian looked at her expressionlessly and said, "From now on, if you have any questions you don't understand, you can only ask me. You are not allowed to ask anyone else. I can explain it to you. That's the condition."

Nanzhi: "......"

She seemed to have guessed something. Could it be that Shen Xingmian was jealous?

"Shen Xingmian, did you feel particularly upset watching Qin Yi explain the problem to me? Are you jealous?"

Nan Zhi's eyebrows instantly curved into crescent moons. The surprise came so suddenly that she was caught off guard. If it weren't for her physical condition, she would have jumped up long ago.
