Even Li Yun's employees can't stand it anymore.

Not to mention the jokingly called Li Yun as the ‘Chairman of Senior Three’, Wu Ke also feels speechless at Li Yun’s cowhide. This is too much to say!

As a high school student, Li Yun can score full marks, write beautiful songs, and write superb programs.

But if you want to say that you have made achievements in painting, you are more powerful than those master painters, that is pure nonsense!

In history books, there are generals who set off at the age of fifteen, the prime minister who manages hundreds of officials at the age of eight, and the emperor who ascends to the throne at the age of three.

But I have never heard of a genius who became a master painter, calligrapher, and writer at the age of 18!

After all, all artists need age precipitation. The older a person is, the stronger the charm of his works.

So Li Yun's words are definitely bragging.

"..."

Gong Qingyu glanced at him, and he felt that Li Yun was probably talking big. She had just started painting for so long, how could Li Yun be better than her?

In the field, only Su Muxin, who has a liking for Li Yun of 100, believed his words, "Brother Li Yun, I believe in you, come on~~~!"

"Please see."

Gong Qingyu drew a geometric figure on the drawing board with a brush, and showed it in front of Li Yun.

Li Yun understood that Gong Qingyu took the drawing board to draw out the graphics of the subject.

After waiting for three seconds, Gong Qingyu said calmly: "My question is: point A and point B intersect at a point outside the circle, and the line x squared plus 5y... Try to prove: the line AC is parallel to the line DG."

Everyone was dumbfounded. They had previously despised Li Yun's bragging, but now they were all blinded when they encountered the high school test questions.

These reporters and elites have not experienced the college entrance examination, but within a year of graduation from college, most of them have to return their high school knowledge to their alma mater. It is impossible to remember at all, let alone know how to solve it.

Only the students in the special class of foreign language middle school took out their mobile phones or paper and pen to try to solve this geometric proof problem.

"First make an auxiliary line and deform the straight line equation to get..."

Compared with them, Fang Hao, a mathematics genius, seemed to be more at ease, almost without thinking, he came up with an understanding idea.

"Make an ellipse."

Just when Fang Hao was so proud and ready to get the final result, Li Yun said, "Take O as the center of the circle and AC as the reference line... It turns out that AC and DG do not intersect."

Everyone looked dumbfounded again.

It took Li Yun only three seconds to reach a conclusion? This Nima is too fast!

Moreover, there is no calculation in the whole process, just stand in place and think for a while to get the answer?

Is it right?

Everyone looked at Gong Qingyu, but saw her nodding blankly.

Fang Hao's expression turned gloomy, Li Yun's method of proof was more concise and clearer than his thoughts, and the method of proof by contradiction gave the answer at once, much faster than his three-step calculation!

"Sequence {an} (n is greater than or equal to 5), a5=2, a8=10, try to prove that for all positive integers n>5..."

As soon as Gong Qingyu's words fell, Li Yun said: "This question is very simple, will an..."

When the two asked and answered, within 20 seconds, Gong Qingyu had already approved Li Yun's answer and continued to ask the next question.

Soon, seven or eight super difficult math problems were solved by Li Yun in the question and answer of the two.
