When Feng Lingxuan came back, the other four people had already begun to work hard to write.

Because it was already the last evening self-study, the sky outside was completely dark, and the weather today was not very good, on the dark canopy, there were only a few faintly shining stars, and even the shadow of the moon could not be seen.

The windows of the study room were open, and the wind rustled in, bringing the fragrance of flowers and plants, which made a few sleepy people feel refreshed.

Wang Ping bit his pen and pondered the solution to this problem, and said: "Alas, this problem is really difficult, can the friendship competition really come up with such a difficult question?" ”

Peng Xiujin was much more relaxed than him, he wrote a string of numbers on the scratch paper, and then said: "I don't know, we are always prepared, we are going for the first place, now do more problems, it will be much easier when it comes to the competition in the future, what do you say?" ”

Bai Hongfeng raised his face of ice cubes that had not changed for 10,000 years, and said in a low voice, "That's right, continue." ”

After saying that, he lowered his head and continued to study, without speaking.

Feng Lingxuan also sat quietly in her seat, writing with a brush.

Seeing that everyone ignored him, Wang Ping simply stopped talking, and simply concentrated on continuing to conquer the mountain of mathematics.

Several people were quiet for more than ten minutes, and soon, there was a sound of chairs shutting in the quiet classroom, and everyone looked up and found that Feng Lingxuan had actually put away the pen and began to organize her schoolbag.

Seeing this, Peng Xiujin immediately asked, "Ling Xuan, are you in any hurry?" Need me to help you take time off? ”

Feng Lingxuan said: "No, I'm done." ”

Crowd: ".........................................."

Everyone: "?????????????? ”

Everyone: "!!!!!!!!!!!!! ”

Wang Ping slapped himself hard, Made, not dreaming!

They are still racking their brains here to calculate, Feng Lingxuan has actually finished it?

What kind of genius level is this, and it's terrifying, isn't it?

Wang Ping was in a slump in an instant, he had always been envied by others as a good student, and now facing Feng Lingxuan, he finally tasted the taste of envy of others.

Wang Ping thinks so, why don't others?

When Bai Hongfeng heard this, he gave Feng Lingxuan a thumbs up, and then went on to go on to his own.

Peng Xiujin had just calculated a question, then he put down his pen and said with a bitter face: "Ling Xuan, you are really amazing, you finished it so quickly." ”

Feng Lingxuan was still the same, she said: "I see that there are a lot of good books in this library, so I won't go back to the classroom, just read the books here." ”

Peng Xiujin listened to her words, and his hanging heart immediately relaxed, he originally thought that Ling Xuan would leave when he was done, but he didn't expect that he was still reading here, and he would be able to get along with Ling Xuan for a while.

Feng Lingxuan could not see their thoughts from their eyes, so Feng Lingxuan stood up, put down her schoolbag, and walked in the direction of the bookshelf.

When the four of them saw that Feng Lingxuan had finished it, they were naturally not far behind, so they immediately lowered their heads and began to write hard.

The classroom was quieter than just now, but footsteps could be vaguely heard, it was Feng Lingxuan shuttling between the bookshelves.

Actually, where is Feng Lingxuan reading something, she is observing Zhuang Yihua to see if he is suspicious.

Feng Lingxuan stood between the high bookshelves, and through the gap between the bookshelves, it was easy to observe Zhuang Yihua sitting at the very edge.

He, like the others, was thinking through the question.

But judging from the flickering eyes in his eyes, he was very anxious now, although he had been writing again, but he obviously filled in a number every once in a while, in fact, he himself couldn't take so long.

Feng Lingxuan looked at him, her eyes becoming deeper and deeper.

She took out her mobile phone, logged in to her account, hacked into the campus network, and soon found Zhuang Yihua's identity information, borrowing this information, Feng Lingxuan could directly view Zhuang Yihua's chat records and phone records, etc.

No anomalies were found in the phone records.

It's just that from the chat records, Feng Lingxuan found out that Zhuang Yihua was dating a girlfriend, and he would tell this girlfriend every day what happened at school, and in addition, the people who contacted him were no longer suspicious.

Feng Lingxuan followed Zhuang Yihua's girlfriend's number all the way down, and found that his girlfriend was closely connected with an unfamiliar number, because now at school, Feng Lingxuan could not retrieve their call records for the time being.

However, through this investigation, Feng Lingxuan can be 100% sure that Zhuang Yihua is definitely an informant of A.

As for whether he specifically monitors himself, this is unknown, Zhuang Yihua and his girlfriend have known each other since junior high school, and they have always had the habit of chatting.

The woman's report to the others had been from recently, and it was obvious that her presence was indeed unexpected by these people, otherwise they would not have been busy contacting them while their identity was still unclear.

Thinking of this, Feng Lingxuan decided that it was necessary for her to test it.

She looked at her watch, it had been almost half an hour, and presumably those people should have finished the last question, at least some of them should be almost finished.

Feng Lingxuan paced to the table, and sure enough, she saw the four of them discussing the solution to the last problem together.

Peng Xiujin only had the best math scores among the four of them, and now he was explaining the second question of this problem to the other three.

Seeing Feng Lingxuan coming, Peng Xiujin breathed a sigh of relief, beckoned to her, and said helplessly: "I really don't know this last question, Ling Xuan, have you done it?" ”

Feng Lingxuan walked over when she heard the words and said, "It's done." ”

When the four of them heard this, they had nothing to love for a while, learning God is learning God, and it was difficult to solve any problem.

Wang Ping hugged his head and said, "Ling Xuan, you are so powerful, why are you still coming to high school, just go directly to college, why do you come to poison us?" ”

Bai Hongfeng received: "That's it." ”

Feng Lingxuan heard that they were making fun of herself, and immediately said, "It's just that the age is not enough." ”

Then, she turned to Zhuang Yihua and said, "Right? Zhuang Yihua? ”

Zhuang Yihua was anxious now, and it took a long time to come back to his senses after hearing the words, and he echoed again and again: "Yes, yes, heroes have been young since ancient times!" yes, yes! ”

Peng Xiujin glanced at Zhuang Yihua strangely when he heard this, and said, "Yihua, you seem to be a little absent-minded?" Are you okay? ”

Zhuang Yihua's body shook when he heard this, and he hurriedly said: "It's okay, it's okay, I'm just thinking about how to solve this problem, it's nothing." ”

I was actually distracted just now, and I was still in front of Feng Lingxuan, which really shouldn't be.
