Old Professor Xie slapped his thigh and exclaimed, "God, who has ever thought of proving it in this way in the past 800 years?" It's a genius! Oh no, he's at least the level of a mathematician! ”

Sun Zi Xie Ran silently looked at the white hand on the video, a little suspicious.

The hand of a mathematician?

What mathematician is not a gray-haired old man? Have such young hands without any wrinkles?

While watching the video, Professor Xie held an old-fashioned fountain pen and wrote along on scratch paper, and kept muttering excitedly: "That's it, so it's like this......"

"How could a god-like figure think of such proof? Let's set A=B......"

The grandson felt that his grandfather might be going crazy, and he didn't listen to any call.

Old Professor Xie grabbed his few hairs and said with some annoyance: "Hey, what does this step mean?" Other...... Don't write so fast, I can't keep up. Video, hurry up and record. ”

Xie Ran said helplessly: "Grandpa, this anchor doesn't seem to have an authorization to record the video." ”

Professor Xie couldn't care about the word elegance anymore, and almost scolded this favorite grandson: "Are you stupid?" Don't you know how to use your phone to record against the curtain? ”

Xie Ran was shocked: "Grandpa, didn't you say that you should respect other people's copyrights?" This is piracy! ”

Professor Xie was cheeky: "This is different...... Hurry up, leave a message and let him stop writing so fast, I can't understand the old man, I can't keep up with the train of thought. ”

The old professor in his seventies almost cried as he grabbed his hair.

After Xie Ran sent a barrage, Bai Chuwei's speed was still unabated, and Old Professor Xie was almost unable to understand it.

"Why didn't he slow down? How can you remind her? ”

Xie Ran guessed: "It should be that this anchor didn't see the barrage." That's right...... If you give a gift, there will be a small reminder on the anchor's side. ”

Professor Xie slapped the table and was very decisive: "Then give me a gift quickly!" ”

Xie Ran held his mobile phone to check it, and smiled helplessly: "Grandpa, this is a rookie video master, his attention is only more than 1,000 points, and less than 3,000 is not qualified to receive gifts." ”

When the old man heard this, he blew his beard and glared, and retorted, "He is not qualified to receive gifts?" Who is eligible? Those influencers who create gimmicks? ”

Xie Ran didn't know why he was scolded by his grandfather......

This is the regulation of people's salted fish video APP, who can blame it? It's not his fault.

Professor Xie suddenly thought of something, his eyes lit up for a moment, and he immediately took his mobile phone and called the teachers of the Department of Mathematics of Imperial Capital University: "Yes, you should immediately notify all the students in the department now, go to the Salted Fish Video APP to follow a video account called 'Everyone Gets God'!" Hurry, it's now! ”

"Don't think I don't know, their group of students don't sleep until the early hours of the morning, hurry up and this is a mandatory task!"

Professor Xie Lao is the head of the Department of Mathematics, and the counselors have to be obedient, obediently in the student group, all the students!

A group of math students still playing games in their dorm room: "?? ”

Is this crazy?

However, they respected Professor Xie a lot, and admired Professor Xie's achievements in mathematics, so they immediately paid attention to this newcomer video master.

In just a few minutes, Bai Chuwei's account exceeded 3,000 followers.

[Ding!] User 'Xie Jin'an' gave the anchor ten cupola rockets and left a message: This anchor, can you prove that it is slower? I'm a little out of your tracks. ]
