"Sit, sit, don't be like this, cheesy! But little guy, I'm very curious about you, I hope you can surprise us this time," Professor Du couldn't help but chuckle after handing the test paper to Liu Xu.

"This is natural, Professor Du, just wait and see!" This time Liu Xu was not modest, and said confidently, Professor Du, who heard this, was obviously very satisfied with the confidence expressed by Liu Xu, and couldn't help but nod and said, "Okay, then my old man will wait quietly, but although this competition is not too formal, I think the timer has begun now, so I won't bother you." ”

After speaking, the old man left 305, and by the way, he helped Liu Xu bring them, and after going out, he found that Professor Li had just ordered Xu Wensong to come out of 306, and the two old men couldn't help but smile at each other and sat up at the door.

In this way, time passed minute by minute, and the originally quiet crowd began to be a little noisy at this time.

"Who do you think will win?" someone asked in a whisper to his companion.

"Who is right, after all, I am really not familiar with that Senior Brother Liu, but I heard that Xu Wensong once challenged three sets of difficult competition practice questions in an hour, and it is said that the correct rate is as high as 100%, and I don't have any pressure on Xu Wensong in terms of time!"

"I've heard about this too, but don't you think Senior Brother Liu's temperament is more like a villain behind the scenes?

After hearing this, everyone around looked at the person who spoke just now like a fool, and you don't have to guess to know that this must be another secondary school boy who has watched too much TV and anime, and has been infected.

Compared with the impetuousness of these people who watch the excitement, at this time, Su Chenfei, Wu Siming, and Su Qingfeng in 301 are much calmer and quieter, some people are reading books there, and some people are even "eating chicken" in that mobile game!

It's not that they don't care, and both sides are full of confidence in Liu Xu and Xu Wensong, who walked in, believing that they will achieve the final victory.

In this way, in the whispered discussion of everyone, half an hour passed, and at this time, Liu Xu in room 305 looked at the test paper on the table, and couldn't help but stretch his waist there with a chuckle.

To be honest, he hadn't experienced this form of exam paper for a while, and he was still a little strange when he did it at this time, but he was quickly adjusted by Liu Xu.

Looking at the dense formulas, numbers, and symbols on the test paper, Liu Xu nodded with satisfaction, and then got up directly.

……

"Huh?" The sound insulation effect in the dormitory is not very good, and the corridor is very quiet at this time, so any movement in the dormitory at this time, the two old men outside can almost detect it, when they heard the voice from Liu Xu's side, Professor Du couldn't help but hum softly, but when he looked at the time, the old man couldn't help but shake his head, thinking that he had heard it wrong, so he didn't care.

It's only been half an hour, and the old man doesn't think that Liu Xu can complete a set of questions in ten minutes, after all, the test questions in front of him are not addition, subtraction, multiplication and division in the first grade of primary school mathematics.

"Knock knock, knock knock!" Just when the old man mistakenly thought that he had misheard, there was a knock on the door, but it really sounded, and when he heard this knock, Professor Du and Professor Li couldn't help but be shocked, and then frowned.

In such a short situation, even if it is a super genius like Xu Wensong, it must be impossible to complete it, assuming that Liu Xu is stronger than Xu Wensong, it is impossible to complete it in this short half an hour, so the two old men think that Liu Xu knocks on the door in such a short period of time, and there can only be one result, and the two old men who thought of this turned their faces darkened, thinking that Liu Xu was irresponsible, and even because of this, they wasted three sets of practice test questions that they prepared silently, which immediately made them dissatisfied.

However, because of the rules they have set, since there is a knock on the door, then they must open the door, and even if they are dissatisfied, it cannot be expressed at this time.

"Click!" At this time, the old man opened the door and looked at Liu Xu with an ugly face, seeing Liu Xu here, he couldn't help but be a little confused at this time, thinking about how to offend this old man, wasn't it okay just now?

"Ahem, old man, I'm done!" At this time, Liu Xu still said stubbornly.

"Hmm! don't check, check?" At this time, the old man asked with some sarcasm, at this time he had already decided in his heart that Liu Xu must not be a physical genius, and he must have more than half of the empty papers, so he still needs to check, the old man just hated him for not arguing, lying, and not about people, so he couldn't help but mock and said.

"That's not necessary, I believe in myself, if it's okay, then the professor, I'll leave first!" At this time, Liu Xu couldn't find a reason, and he couldn't be rude to the old man, so he could only say in a good way.

Hearing this, the old man was even more dissatisfied, and waved his hand with some disgust, seeing this Liu Xu, he quickly said hello again with a wry smile, and passed by the old man.

Although I have heard of some old professors with very strange tempers before, I have only heard of them, but I have never really seen them, but today I finally saw them.

At this time, Xu Wensong's train of thought in the dormitory 306 next to him was also interrupted by the noisy sound outside, Liu Xu said that he had heard more or less about handing in the papers, and he was looking at the fact that he had only completed half of the test papers, and his heart couldn't help but be impatient at this time.

However, Xu Wensong is Xu Wensong after all, after the initial irritability, knowing that even if it is time to hand in the paper now, he will let himself stabilize as soon as possible, and put his energy into the test paper in front of him from the beginning, and now he can only strive for the highest accuracy rate.

……

"Lao Li, do you want to take a look at that kid's test paper and see how he is doing?" Just after Liu Xu left, Professor Du couldn't help but ask Professor Li, he was somewhat unconvinced at this time, Liu Xu's fanfare competition was just to amuse everyone.

Hearing Professor Du's words, Professor Li couldn't help but think about it, he knew Xu Wensong very well, and he was also extremely concerned, even if he was half a disciple, he also knew his ability, and knew that he couldn't get out for a while, so he couldn't help but nod to Professor Du, and then the two old men walked into 305 together.

"This is!" When they took out the test questions made by Liu Xu from the sealed bag, the two old men couldn't help but be shocked, and then glanced at each other, the test papers in their hands were completely different from the blank papers they imagined, and the entire test paper was densely packed at this time.

"I'll look at this! Look at that!" At this time, Professor Du said loudly, hearing this, Professor Li also nodded, and then picked up the test paper on the table and watched, at this time there was silence here, if it were not for the breathing of the two old men, it could give people the illusion that time was still.

"Genius! This is not something that can only be described by heaven!"

"Hey, at this time, I finally understood that the headmaster's choice was indeed a demon that has been rare for decades!"

I don't know how long it took, in the 305 dormitory, there were two old people's exclamatory voices, and at this time, Liu Xu did leave early, found a place to wash his face, and then returned to the 301 dormitory.

And those who met Liu Xu halfway couldn't help but be shocked, and after Liu Xu left, the scene suddenly became chaotic.
