After a whole night of struggle, Professor Wang slowly put down the scroll in his hand.

His face was still unusually red, and even his heart was pounding.

He felt as if he had discovered the greatest mathematical genius of the 21st century.

"I didn't expect that guy who was so out of tune to have such a high attainment in mathematics that I couldn't even reach it!" Professor Wang sighed, feeling a little depressed in his heart.

After a night of speculation, all of Lin Fan's formulas were correct!

In other words, Lin Fan successfully solved the math problem that is known as the most difficult in history!

That problem, which stumped all mathematicians in the world, was successfully solved by a high school student?

It's hard to imagine how shocked the whole world will be when this news is released!

Although Professor Wang felt that all of Lin Fan's answers were correct, he was still very uneasy.

He hesitated for a moment, pulled the phone out of his pocket, and dialed a number.

"Hey, Lao Zhang, I have something urgent, you hurry up, it's in my office!" Professor Wang said in an anxious tone.

Professor Zhang and Professor Wang are classmates and have a very good relationship, and both of them are absolute masters in the field of mathematics.

This Olympiad competition was led by the two of them, and they were the main propositions.

"Lao Wang, what's the matter? I don't let people sleep well early in the morning!" Professor Zhang yawned hard after receiving Professor Wang's call, and then said.

As an elderly person, his sleep is very shallow and the time is short.

He had just slept for a while, and it was when he was sweet when he was woken up by Professor Wang's phone.

After he heard the ringing of the phone, he hesitated in his heart, whether to answer or not, he wanted to continue to make up for sleep, but as soon as he saw that the number was Professor Wang's, he directly picked up the phone.

"Sleep, sleep, hurry up and come over to me, there's something urgent!" Professor Wang said very directly, his tone was very anxious.

"Eh, Lao Wang, what the hell is going on? It can't be your daughter-in-law who cuckolded you......" Professor Zhang guessed with some suspicion.

Other than this, he could no longer think of anything that could make Professor Wang so gaffe and anxious.

"I'll take you a big-headed ghost, it's something else, you don't have ink, come over quickly. Professor Wang scolded and then said.

Her chest rose and fell, and she was almost by Professor Zhang.

Originally, I stayed up all night last night, and my body was a little weak.

Now that Professor Zhang is so angry, he feels that he may faint and fall to the ground at any time.

"Okay, Lao Wang, then you wait for me for a while, and I'll be there soon. Professor Zhang saw that Professor Wang was so serious, and he said with a straight face.

"Well, hurry up. Professor Wang said.

After saying that, Professor Wang hung up the phone and began to organize his thoughts.

About ten minutes later, Professor Wang's door was woken up by a knock.

Professor Wang guessed that Professor Zhang was coming, and he hurriedly ran to the door to open the door.

As soon as his hand grasped the doorknob, the office door was kicked open.

With a "bang", the door frame slammed into the bridge of Professor Wang's nose.

"Holy!" Professor Wang screamed in pain, then squatted on the ground, covering his nose with his hand.

Blood gushed out from his nostrils, and it flowed through his palms.

"Oh, Lao Wang, I'm really embarrassed. Lao Zhang laughed, but he didn't look embarrassed at all.

"Nima coins!" Professor Wang was so angry that he wanted to kill now, he felt that his nose was sore and sore, and tears flowed out of his eyes.

"I forget, you said how old you are, and you still learn to be like a child, crying your nose there. Professor Zhang teased.

Professor Zhang has always been such a person, disrespectful to the old, and very "naughty", always like to play tricks on people.

He is like the old naughty boy Zhou Botong in costume dramas, although it is not so exaggerated, but it is not far off.

So his friends gave him a nickname, and everyone called him an old child.

Professor Zhang is 72 years old, but he is still very energetic, and he does not look like an old man at all.

"Lao Zhang, you wait for me, sooner or later I will have to make you bastard pay the price!" Professor Wang said hatefully.

He straightened up in pain, then walked into the bathroom and began to deal with his bleeding nose.

When Professor Zhang saw Professor Wang go to the bathroom, he casually found a place to sit down.

He crossed Erlang's legs, whistling in his mouth, and began to wait for Professor Wang to appear.

About three minutes later, Professor Wang put a band-aid on his nose, and then walked out with a black face.

Professor Wang glared at Professor Zhang viciously, who was sitting there.

This old bastard doesn't even know how many times this is teasing me!

Don't let me get a chance, or I'll let you know why the flowers are so red.

Professor Wang thought to himself, and his eyes were full of resentment when he looked at Professor Wang.

If he weren't a university professor, he would definitely choose to strangle this old thing!

It's so annoying, how old are you when you say it, you always play these tricks!

The key is, I'm still tricked! Who am I messing with, why are you so back!

It doesn't matter if he was hit by Lin Fan's guy yesterday, he was actually plotted by Lao Zhang just now!

"Lao Wang. Tell me something. Professor Zhang said to Professor Wang.

"Whew......... It's a bit too shocking, you let me slow down first. Professor Wang took a deep breath and said.

Even after so many years of cultivation, he was still hit by Lin Fan.

"What's the matter? As for it? It actually scared you like this. Professor Zhang glanced at Professor Wang, and then a look of disdain hung on the corner of his mouth.

"Believe me, if you know this news, your shock level will definitely not be much stronger than mine!" Professor Wang was amused after hearing Professor Zhang's words, and then said with a straight face.

"Huh......... I'm not like you, I'm that old, and I'm still crying. Professor Zhang said disdainfully.

"........." Professor Wang had a black line, and the corners of his mouth kept twitching.

"Lao Wang, don't sell it, hurry up and say, I have to go back to sleep. Professor Zhang yawned fiercely, and then said impatiently.

"Goldbach's conjecture has been solved!" Professor Wang said after taking a deep breath.

"Oh, crack it, crack it, what can you do?" Professor Zhang said casually, holding Erlang's legs.

"Hey, old Zhang, did you listen to me?" I said, Goldbach's conjecture has been cracked!" Professor Wang said to Professor Zhang.

"Wait a minute, what are you talking about!???" Professor Zhang didn't pay much attention to Professor Wang's words just now, but now after hearing Professor Wang's words again, he said with a shocked face.
