"Professor Zhang, where is the wizard from your school?" asked President Yan as he looked at Zhang Wenbo with a smile.

The other invigilators also looked at Zhang Wenbo with curious eyes.

"Over there, sitting behind Ning Chang. Zhang Wenbo pouted in Su Chen's direction.

"What a talent!" "President Yan couldn't help but praise Su Chen after seeing him.

"This young man is not only talented, but also very handsome!" said a female teacher with a smile.

"Professor Zhang, who do you think will win the championship in this semi-final?" asked a younger male teacher with a smile.

"They're all good seedlings, and I wouldn't be surprised who wins. ”

Zhang Wenbo smiled gently, and added: "Of course, I am naturally more optimistic about the students in our school." ”

Everyone was speechless, and if they wanted to say that they were optimistic about Su Chen, they would be blunt, what kind of prelude was there, it was too hypocritical.

"Su Chen's answer sheet in the preliminary competition is perfect, but Nan Xiaoran of our school is praised by Dean Zhang as a rare genius in Huaqing for decades, and he will not be inferior to him. A male teacher at Huaqing University said confidently.

Dean Zhang is the dean of the School of Mathematics of Huaqing University and the president of the entire Chinese Mathematical Society.

"Hmph, what's so great about that old guy, I also said that Su Chen is a mathematical wizard that we have rarely met in a hundred years in China!" Zhang Wenbo replied unconvinced.

A group of teachers were speechless.

A rare mathematical genius in a century is inevitably too exaggerated, but because of Zhang Wenbo's authority in the mathematical community, they dare not refute it.

"Okay, okay, everyone is almost back, let's get ready to start!"

"Now, all students sit away from each other a little, hand over all electronic devices such as mobile phones first, it is strictly forbidden to talk to each other in the middle of the exam, if there is any violation of the rules and cheating, will be disqualified from all future mathematics competitions, and their respective schools will also be severely punished, so please abide by the examination discipline and rules, and answer the questions carefully. ”

After President Yan announced the precautions for the exam, the ten invigilators began to distribute the exam papers and scratch papers.

An exam paper consists of five sheets of paper, each with a proposition written on the top, a large blank area below is the answer area, and the scratch paper is also five large sheets per person.

Although there are only five questions, which seems to be very few, each question requires a lot of calculations and deductions.

Su Chen got the exam paper and looked at the first question.

This is an analytic geometry question, and the complexity of the geometric pattern is simply beautiful enough for 99% of college students in the country to have the urge to tear up this exam paper at the first glance.

"This question is a bit level. ”

The corners of Su Chen's lips curled up.

The first question of the semi-finals is more difficult than any of the previous preliminary rounds, and it is more than a little bit hard.

Su Chen was not in a hurry to make a move, he supported his chin with his left hand and looked at the problem, and turned the pen with his right hand familiarly, recalling all the mathematical formulas and theories he currently controlled in his mind for screening, wanting to solve this problem in the simplest way.

"What is this kid doing? Zhang Wenbo looked at Su Chen's leisurely appearance, which was very contrary to the tense atmosphere around him, and he was angry.

"Hmph, is it too difficult to give up if you don't move your pen for a long time? This is a topic that Dean Zhang racked his brains for, so he is dumbfounded!" The male teacher from Huaqing University also observed Su Chen, saw him sitting there leisurely turning the pen, and then looked at Nan Xiaoran, who had already begun to solve the problem, and felt a little proud in his heart.

In his opinion, Su Chen is capable, and he can be regarded as a genius among students of the same age.

However, the talent in mathematics is still not enough to be compared with a genius like Nan Xiaoran, and the problems in the preliminary round may be perfectly solved, but if the problems are more difficult, there is no way to start.

Time passed minute by minute, Su Chen still sat there without moving, the pen in his hand was called a 6, and he could go to perform acrobatics.

"Ahem......"

Zhang Wenbo appeared behind Su Chen at some point, clenched his hands into fists and put them to his mouth, and coughed dryly.

Su Chen was immersed in his own deduction and didn't notice it at all.

"Ahem, ahem, ahem!!"

Zhang Wenbo frowned slightly, and his voice raised an octave and coughed.

Around the examination room, the other invigilators all cast meaningful glances.

It seems that this Professor Zhang is in a hurry.

Su Chen was just finished deducing at this time, when he heard the cough and looked back at Zhang Wenbo, he whispered with a strange face: "You have an uncomfortable throat?"

Zhang Wenbo's old face darkened in an instant, and he reminded with a stern face: "Hurry up and answer the question, what do you care." ”

After saying that, he walked away with his hands on his back, pretending that he was just passing by.

Su Chen pursed his lips, probably understood what the old man meant, ignored him anymore, and wrote directly in the answer area.

What is scratch paper?

Does the true god of learning need this thing?

Solving math puzzles is the same as writing code words, and it is no problem to have a smooth mind for ten more than ten a day, but if it is Kavin, it will be immortal to death.

Su Chen had already deduced the entire proof process in his brain, and he only needed to write out the process board.

As a result, most of the students scratched their heads, and the scratch paper was filled with a large number of difficult problems, which once again became the process of Su Chen's practice of calligraphy.

Smooth sailing, overnight.

I have to say that the person who came up with this topic is indeed a ruthless person, Rao is Su Chen has already completed the process, and he wrote without pause, and he wrote for nearly eight minutes.

The entire blank space for solving the problem is filled.

After glancing at his near-perfect proof process, Su Chen smiled with satisfaction, put the paper at the bottom, and then began to solve the second question.

Not far away, the male teacher of Huaqing University, who glanced at Su Chen from time to time, saw Su Chen put away the first test paper, and a look of surprise flashed in his eyes.

"Could it be that he solved it?" the man frowned and paced towards Su Chen.

Su Chen was deducing the second question in his mind, when he suddenly felt that the light was blocked, and looked at the middle-aged man standing behind him with a puzzled look.

"Uh-huh......"

The man cleared his throat with some embarrassment, touched the hair he had washed on the top of his head, and walked forward, pretending to observe every student answering the question on both sides.

Su Chen raised his eyebrows strangely, continued to deduce, and was about to put pen to paper, when the chairman of the Demon Capital Mathematics Society Yan paced over again.

"You write your question, see what I do. President Yan said.

"You're blocking my rays. Su Chen said with a bitter face.

"I'm sorry, I'm sorry. ”

Chairman Yan smiled awkwardly and left.

"What's the matter, it's all against me?"

Su Chen muttered to himself in his heart.
