Xueba, I beg you to go and escort him quickly!

Then a message was posted in a WeChat discussion group with only a few professors.

"Old fellows, student Xu Heng gave me two different solutions to this problem."

This is not the discussion group of Peking University!

Moreover, the paper group for this National Math Olympiad competition comes from several top mathematics professors from famous universities across the country.

Some of them have made great contributions to the domestic mathematics community!

"I know, this question is nothing to you."

"However, after reading the topic, he quickly gave two ideas, and told me by dictation."

As soon as these words came out, all the words that these professors were typing were deleted, and they began to reorganize the language.

One quickly sent out, "I don't think there is any need for review."

"+1"

"1"

"Ah."

The discussion group of a few people is very clean. If there is something to say, agree is "1", and disagree is "2".

Simple!direct!efficient!

"Old Zhu, when can I arrive?"

This time, the group that produced the papers was still at Peking University.

Both board and lodging.

Zhu Tiesen, "It was already late when we went back! Don't wait, everyone, let's talk about it tomorrow morning!"

"1"

"1"

"1"

After that, there is no news in the group.

Zhu Tiesen put down his phone and looked at the driver, "Your phone should also be quieter! Don't make any sudden calls, it will disturb Xu Heng."

"Okay, Professor Zhu."

The driver is cautious.

Even Zhu Tiesen took care of people like this, he had better treat them well.

He has never driven such a stable car!

Hold the steering wheel with both hands...

He has not had two hands to hold it for many years.

"hiss!"

He is very serious.

Stare straight ahead.

When he arrived at the service area, he was busy, too.

He even bought food and drinks for Xu Heng and Zhu Tiesen out of his own pocket.

Zhu Tiesen, "Thank you!"

Xu Heng, "Thank you."

The driver smiled, "You two are welcome! This is what I should do!"

"Mr. Xu, did you sleep comfortably in the car before? I bought a pillow in the nearby shop. When you sleep next, it should be more comfortable."

"Professor Zhu, you have it too!"

This treat!

Super VIP!

Xu Heng gave the driver a thumbs up.

This guy, what a service.

After dinner, Xu Heng called his family.

"Dad, how is home?"

Xu Yueshan, "The house was built beyond my expectation! More people came! So it was very fast!"

"Oh, that's right! Let me tell you something, it's their house next door..."

Xu Heng, "Dad, my mother told me."

Xu Yueshan, "I've said it, and I want to say it too! It's so relieved! Ahahaha!"

"Let me tell you, he doesn't dare to go home every day. Not only is he afraid to go home, but he also goes back to the company with the construction team, and then drives back!"

"This time around, he still drives by himself!"

Xu Heng, "Uh..."

"Dad, you put down your fiddle first! Let me tell you something!"

"I went to the capital again, and I'm already in the service area on the expressway."

Xu Yueshan, "Which competition did you go to? Or..."

Xu Heng, "National Mathematics Olympiad, let me tell you, let you know, don't worry."

"But this time it's closed, and it's been about ten days. If you can't contact me during this period, it means that my mobile phone signal has been blocked."

Xu Yueshan became excited all of a sudden, "Damn it! You won't be cheated, son?! You..."

Xu Heng, "Dad, don't get excited, don't worry! The location is still at Peking University! There is a professor with me!"

Xu Yueshan, "Are you one of your older fans again?"

"Forehead……"

Xu Heng, "Dad, isn't your analogy a little too much!"

Xu Yueshan also asked seriously, "Isn't it?"

"Uh... that's it!"

Xu Heng didn't explain much, anyway, he expressed everything he wanted to express.

"I'll hang up first! Dad!"

From Xu Yueshan's side, "Okay! Goodbye!"

The phone just hung up.

Zhou Xiu'e leaned over, "Son's phone? What's the matter?"

Xu Yueshan, "My son said that he is going to participate in some kind of competition again. It seems to be a math competition!"

Math competition?

Someone in the construction team immediately left to pick up the conversation, "Old He's son is also going to participate in some math competition. The sons of your two families are about the same age, right?"

"Old He, your son is also in high school, right? When is he in high school?"

Old He's face turned dark, "Gao, sophomore!"

"Yes! It seems that Mr. Xu's son is also a sophomore in high school. What a coincidence! What math competition are you going to participate in?"

Old He Pi smiled, he didn't want to talk about these topics.

As a designer, he saw Xu Heng's building gradually being built, and it was more magnificent and beautiful than theirs, and he had mixed feelings in his heart.

"Hey……"

Han Honghu came over, "What a sigh! Old He, isn't this a good thing?"

"By the way, Mr. Xu, what math competition is your teacher Xu participating in?"

"Is it the same as Lao He's?"

"If it's the same, what a coincidence!"

"Maybe, the two of you can still get to know each other!"

"Old He, what competition is your son participating in?"

Old He, "Two days ago I called and said, what is the National Mathematics Olympiad!"

Xu Yueshan nodded, "That's right! My son said the same thing. He said that the mobile phone signal will be blocked after he goes there. It's very strict! It feels like a big competition!"

He also added, "I'm leaving today! Someone is coming to pick me up!"

Old He frowned, "That's not right! My son didn't say that the mobile phone signal is blocked, and the game will not start until half a month later! What is your son doing so early? You won't be deceived, right?"

Xu Yueshan was a little skeptical at first, but it doesn't matter, it's over for him!

Lian took out his mobile phone and called Xu Heng.

"Beep...beep...beep..."

Xu Heng answered the phone, "Hello? What's wrong with Dad?"

The sound is a bit small!

He turned on the loudspeaker, "Son! Have you been deceived? If you are going to participate in the competition, how can you block the signal of your mobile phone! Besides, the competition will start in half a month!"

Xu Heng, "Dad, how did you know?"

Xu Yueshan, "We've reached the end of the conversation! Lao He's son also participated in the competition, saying that it will start in half a month!"

Xu Heng, "Are you sure it's the same match?"

Zhou Xiu'e was also anxious, and yelled from the side, "It's the National Mathematical Olympiad! Aren't you?"

Xu Heng, "Oh, it's this..."

Before he finished speaking, Zhou Xiu'e interrupted, "Son! Where are you? Come back! I'm very worried about you!"

Xu Yueshan, "Give us your location! We'll pick you up! This is no joke! Son!"

"As soon as I heard that the mobile phone signal needs to be blocked, I thought it was tricky!"

Xu Heng said in relief, "Don't worry! It's okay! You are just thinking too much! I am with Professor Zhu now!"

"Professor Zhu, my parents are on the phone..."

Zhu Tiesen said directly, "Hello, please rest assured, I invited Xu Heng to Peking University!"

"The reason why he went so many days in advance is because we are going to produce papers together!"

"Student Xu Heng didn't go to take the exam, but went as a member of the exam team!"

Xu Heng, "Uh..."

He actually wanted Professor Zhu to say something, and then asked Xu Yueshan and Zhou Xiu'e to search for this professor from Peking University on the Internet...  

But now it's good, Zhu Tiesen said it directly.

"Hey?"

"Maybe you think you heard it wrong! But please believe your ears!"

"Student Xu Heng is not a contestant, he is a member of the test group! And I am one of them!"

Xu Heng, "Ahem! It's ok, Professor Zhu is ok."

The phone was returned to Xu Heng, and Professor Zhu was still smiling at Xu Heng.

As if to say, "You're welcome."

Xu Heng didn't plan to explain this at first, but Zhu Tiesen didn't expect to say it first.

It was eerily quiet on the phone.

Xu Heng, "Hello? Parents, are you listening?"

"Hey! Is the signal bad on the highway? Why don't you talk!"
