There is no place to stay here! Ye Xuan secretly said, as he was about to turn around and leave the classroom, the sound of the system appeared.

"Ding! Trigger option, please host to make the following choices:

Option one: do nothing, leave directly, reward: none

Option two: choose to overcome this difficult math problem, reward: mathematical ability. "

The sound of this system directly illuminates the hope in Ye Xuan's heart like the sunlight. Ye Xuan couldn't help but burst out laughing.

Li Yan was taken aback by Ye Xuan's sudden laugh, and after reacting, his entire face immediately became black, and his anger was skyrocketing.

"It's over, Ye Xuan is probably crazy."

"Humph, is that needless to say, Ye Xuan must not be able to withstand the pressure, go crazy."

"Ye Xuan, what do you want to do!" Li Yan said angrily at Ye Xuan.

Ye Xuan was brought back to reality by the angry voice of Li Yan, and then said: "Teacher, don't be angry, I just thought of how to solve this problem."

"Wow--"

The people present were in an uproar, everyone was shocked by Ye Xuan's breath.

"This Ye Xuan is really a big talk, he said he would do this question, ridiculous."

"Huh, I want to see how he ends!"

"System, I chose to overcome this difficult math problem." Ye Xuan secretly said.

"Ding! Congratulations on the host's successful choice and the reward (mathematical ability) has been issued."

Ye Xuan became very confident at this moment, and when he solved the problem perfectly, he was really looking forward to the wonderful expressions of these people.

Ye Xuan quickly looked at the math problem on the blackboard.

"Ding! Check the trigger option, ask the host to make the following choices:

Option one: choose to strengthen mathematical ability, reward: none

Option two: Directly shake hands away, reward: none. "

"Choose to strengthen mathematical ability." Ye Xuan said without hesitation.

"Ding! Congratulations to the host for making a successful choice, reading the questions will start to strengthen the mathematical ability..."

Ye Xuan quickly browsed math questions.

"Ding! The host looks at the subject, +1 math ability, current progress: 1/10, current level: elementary."

"Ding! The higher the mathematics ability level and attribute points, the stronger the host is in the field of mathematics until it reaches its peak."

As Ye Xuan browsed through a whole number of math questions, the sound of mathematics enhancement continued in his ears.

"Ding! Mathematics +1..."

"Ding! Mathematics +1..."

...

"Ding! Current progress: 11/100, current level: intermediate."

"Ding! Trigger intermediate math skills, the answer is being delivered..."

Last second Ye Xuan was ignorant of this math problem, and the next second his brain appeared a solution to this math problem.

I saw Ye Xuan walked to the podium and picked up the chalk, then turned around and wrote the correct answer on the blackboard.

"Oh, uh..."

Ye Xuan's speed is very fast, and after a while, Ye Xuan has written a third of the answer.

One minute later, Ye Xuan wrote all the answers to the whole question. He turned and threw the chalk into the chalk box, and then looked at Li Yan and said, "Teacher, I have finished writing."

Li Yan looked at the dense answers on the blackboard, and there was a trace of surprise in his eyes.

"How is this possible?" Li Yan was shocked, frowning slightly.

Li Yan originally thought that Ye Xuan gave up directly, but did not expect to turn around and wrote the answer to this question. The whole blackboard was densely packed.

"Lying trough, what happened, Ye Xuan wrote it?"

"My God, he, isn't he the tail of the crane? It's unbelievable."

Many of the classmates below exclaimed.

"Everyone shouldn't panic. Ye Xuan must have written a mess. He just wanted to get through. He will never let him succeed."

I don't know who shouted such a sentence, and everyone responded.

"Yes, yes, this must be the case. Fortunately, you should be reminded in time, otherwise Ye Xuan would have cheated you."

"Teacher, you must check it carefully. You must not let Ye Xuan succeed."

At this time, Li Yan also reacted. He looked at the answer on the blackboard and secretly said: "Ye Xuan, you have such a blinding way. It's almost fooled by you."

"You can rest assured, I will check it carefully, as long as you make a mistake, then don't blame me."

Li Yan walked towards the blackboard, he took out the correct answer and started to check it, while Ye Xuan was calm.

"Cut, no matter how you check it, this answer is given by the system, how can the system go wrong." Ye Xuandan murmured calmly.

After a few minutes, Li Yan checked the answer to the whole question. At this time, his face was full of shocked expressions. His heart was as frantic as the waves in the storm, and his whole body was shaking with shock.

"This, how is this possible..." Li Yan murmured in shock.

It took Li Yan a lot of time to study this question. Even if he answered it, it would take more than ten minutes to get it.

However, Ye Xuan finished this question less than two minutes before and after. This speed almost shocked him like a ghost. The most frightening thing was that Ye Xuan's answer was completely correct.

"Teacher, how is this, is Xuan Xuan wrong?" Some of the students below asked.

It took a few minutes for Li Yan to adjust, and there was a little embarrassment on his face.

"That, that Ye Xuan's answer is correct!"

The entire classroom became silent at once!

Many classmates look at me, I look at you, all with shocked expressions on their faces.

"Lying trough, Ye Xuan, he was right, my goodness!"

"It's unbelievable. It's unbelievable. Ye Xuan did it right. How did he do it?"

Faced with the shock of everyone, Ye Xuan smiled very calmly, then looked at Li Yan and said: "Teacher, since I have done this math problem correctly, shouldn't the matter of sleeping be over?"

"Cough..." Li Yan coughed awkwardly, and then said: "You, you go back to your seat. After that, listen carefully, don't take a small class in class, understand?"

"Good teacher." Ye Xuan nodded and said, then turned around and walked towards his place dashingly.

Along the way, Ye Xuan saw many students cast shocked eyes on him, and the situation of gloating and scourge had changed dramatically when he first went up.

"Hey, this is just the beginning, there will be more shocking moments in the future." Ye Xuan secretly said.

This episode ended quickly, Li Yan began to explain the knowledge, Ye Xuan will naturally not sleep in the classroom, if he is caught again, it will inevitably be criticized and educated by Li Yan.

"Since I already have the ability to strengthen mathematics, if I read through the mathematics textbook again, then this mathematics ability should continue to be strengthened." Ye Xuan murmured, and then took out the mathematics textbook from the drawer.
