God-level Xueba system

Supervisor Chen still had a look of disdain just now, thinking that this kid was just here to make up the numbers, and the previous choices and filling in the blanks were done so quickly, obviously he was being fooled!

But when he took a closer look at Yan Xin's big question, he was dumbfounded on the spot!
Supervisor Chen graduated from the prestigious 985 University, so he naturally knows the university's professional knowledge like the back of his hand.

This year's competition questions, the last four finale questions are the calculation of differential equations, listing the categories of transition metal nitride coatings and giving a brief introduction, listing the basic formulas of NP-complete problems and doing simple calculations, and explaining physics dark matter in .

This kind of question looks at many college students in universities, and they may not be able to do it!
But the ruffian boy in front of him actually wrote it all!
And the most surprising thing is that the steps of all the questions are listed in an orderly manner, and there is no sign of confusion at all!
Supervisor Chen was stunned on the spot!

Could it be that this kid didn't go through the back door, but really has this strength?
But isn't this too perverted?
He is a high school student!
Supervisor Chen looked a little bewildered, he didn't notice that Yan Xin was about to get up to hand in the paper, this negligence, the two of them bumped into each other directly.

"Ouch!"

"Axi! I'm sorry! Teacher, I didn't realize you were standing behind me!"

"It's okay! Classmate, do you want to hand in the paper?" Supervisor Chen asked Yan Xin while covering his aching forehead.

Yan Xin nodded.

All the examinees raised their heads in surprise. The boy with chicken coop haircut answered all the questions in less than an hour?

No one will believe it!

And Zhang Ze naturally looked at Yan Xin with disdain.

This force probably knows nothing, so I handed in the paper so early, right?
Although there are not many questions in this question, the following big questions are all knowledge that I have never learned before. How could this kid do it!

"Don't whisper to other students!" Supervisor Chen frowned and looked back at everyone.

Everyone quickly lowered their heads and answered the questions seriously.

Handing in the test papers in advance does not allow you to leave the examination room in advance, which is just right, Yan Xin fell asleep on the table fortunately.

I've been staying up all night reading books lately, and I'm really exhausted!

"Ding Ding Ding!"

"Okay! The exam is over! All students, please stop answering the papers! I'll go down and collect the test papers!" After Supervisor Chen finished speaking, he quickly got off the platform to collect the papers.

"Oh my God! This question is so difficult!"

"Yeah, it's okay to fill in the blanks in the previous choices, but the big questions in the back are simply not made by humans!"

"Cool cool! It seems that this year's recommendation is hopeless!"

"I think so, hurry back and review, and prepare for the college entrance examination!"

These questions really stumped the top twenty students in the school year, and even Lin Hui kept frowning after the exam.

This question is really beyond the ability of high school students!
"Hey! You got caught up so fast, so it was just for sleeping! What? Didn't get pentakill last night, so you fought all night?"

Before Yan Xin woke up, Zhang Ze's annoying voice sounded beside her.

"Then look! Last night's teammates are too rubbish to move!" Yan Xin smiled.

"Really? You are so good at playing games, why do you still take the exam? By the way, why are you handing in the paper so slowly? I thought you would hand in the paper in 10 minutes!" Zhang Ze joked.

"Hehe, I really want to! But I'm afraid you'll be too surprised!" Yan Xin said very pretendingly.

"Hey~ The last few questions are not stressful~ Differential equations, transition metal nitride coatings, basic formulas for NP-complete problems, dark matter! Tsk tsk tsk, the questioner is really kind this year, unexpectedly asking such a simple question !" Yan Xin yawned, got up and was about to leave.

This sentence immediately attracted everyone's attention.

Everyone stopped talking about the content of the exam, and focused their eyes on Yan Xin.

What Zhang Ze meant by saying this was to ridicule Yan Xin. Since it was a trick, he only needs to hand in the paper in 10 minutes.

Didn't expect this kid to say that the last question is easy?
Fuck!
It's the first time I've seen such a pretentious one!

"Hehe, it doesn't hurt your back to stand and talk, but what are you talking about dark matter?"

Zhang Ze was sure that Yan Xin would not be able to answer the question. The current high school physics knowledge is magnetic field, and more in-depth mechanics, electricity and heat.

But the term dark matter is very unfamiliar to the high school students here.

Lin Hui also came over at this time. Seeing her distressed appearance, she must not know what dark matter is.

Yan Xin didn't intend to explain at first, but she looked at Lin Hui with a dazed expression, it seems that today this force has to pretend!
"The so-called dark matter!"

All the students pricked up their ears to listen to Yan Xin's explanation.

"It's dark matter!"

Hey!
Many students looked at the giggling Yan Xin speechlessly. This kid is already joking around at this time!

Zhang Ze laughed even more arrogantly!

This silly dog ​​is really pretending to be a calf!
Sure enough, nothing will happen!

Lin Hui was also amused by Yan Xin at this time, she covered her mouth and didn't know what to say.

Yan Xin cleared his throat, and his face became serious in an instant: "Dark matter, in theory, is a kind of non-existent matter that may exist in the universe. It may be a component of the universe, but it is not a component of any celestial body. !"

After Yan Xin finished speaking, everyone who was still laughing at Yan Xin stopped talking.

Even Zhang Ze opened his mouth wide in surprise.

"Scientific research today shows that dark matter does exist, but people know very little about the properties of dark matter!" Yan Xin explained.

"Student Yan Xin, can you explain the properties of dark matter?" A frail girl wearing glasses asked.

Yan Xin smiled and continued: "Although dark matter is not a component of a celestial body, it should have mass, but the mass of a single dark matter particle has not been determined yet!"

Zhang Ze glanced at his lips: "I'm not sure what you are talking about!"

"If I knew the mass of dark matter particles, would I fucking still use it here to study? Lao Tzu has long been famous all over the world!"

Yan Xin was too lazy to talk to such a person.

How ignorant!

Lin Hui also said something at this time: "Student Zhang Ze, please don't interrupt when others are talking! Yan Xin, please continue talking!"

Lin Hui sat at Yan Xin's desk, leaning on her arms, and listened carefully to what Yan Xin had to say.

Obviously, Lin Hui is also very interested in this aspect of knowledge!

Looking at Lin Hui's beautiful face, Yan Xin couldn't help swallowing, and then continued to explain to everyone.

"Dark matter is highly stable. Since evidence of dark matter exists at different stages of the formation of cosmic structures, dark matter should be stable on the time scale of cosmic age; and through computer simulations of cosmic-scale structure formation, it can be known that the speed of movement of dark matter It should be lower than the speed of light! Otherwise, the universe cannot form the observed large-scale structure under the action of gravity”

Everyone, including Zhang Ze, listened to Yan Xin's story in surprise, and completely forgot about going home!
