Friday, June 21st.

At four o'clock in the afternoon, Li Zheng took his suitcase and returned to his community after being away for a few days.

Some children had already finished school and were chasing each other in the yard in twos and threes.

The elderly people who had picked up their children gathered together to chat, looking around at their children from time to time to avoid getting lost.

Such a life-like scene suddenly changed due to Li Zheng's return.

At first, a fat man riding a two-wheeled electric scooter rushed to Li Zheng's side: "Are you brother Li Zheng?"

"It's me, what's wrong?"

"Haha." The little fat man smiled, then turned again, and the bicycle slid towards his friends, "It's him, he is Li Zheng!"

These children also looked like primary school students, but they were not as outgoing as the little fat boy. They did not dare to come directly, but looked over from a distance with their necks stretched out.

"I'll just say yes!"

"Don't he have to go to school?"

"If you are so good at studying, you shouldn't need to go to school, right?"

Li Zheng listened to the children's discussion and just smiled.

But unconsciously, I have paid attention to my posture and appearance.

As a role model for children, it is inevitable that he will also have some idol baggage.

Those who act and sing must be very charming, and those who are good at learning must not fall behind.

Before I knew it, I had become a study idol.

Thinking about the dream of allowing more children to be born and become learning stars.

He felt that the burden on his shoulders was heavier.

Well, the world needs learning stars.

While he was adjusting his walking posture, a familiar neighbor, an old man, waved to Li Zheng.

"Zhengzheng is back."

"Hello grandpa."

The old man walked up to Li Zheng and smiled broadly: "I won the championship. I'm just waiting for you to go to the International Olympiad."

An ordinary grandpa would naturally not be able to talk about such a thing as the International Olympiad.

But this courtyard is a little different after all. As the in-house dormitory of Ning'er's unit, the most common old men and women started out with bachelor's degrees in science and engineering, and most of them know a thing or two about competitions.

I just didn't expect that grandpa would know such a specific thing. After all, things like physical competition are not big news in society, and this grandpa is not a physics major.

Li Zheng didn't have time to think too much, and immediately waved his hand and said: "Good morning, grandpa, you can only enter the national team through training and selection."

“Hey, you’re number one in the country and you’re afraid you won’t be able to join the national team?”

"It happens occasionally."

"Haha, just like your mother, she is very capable and hides everything." Grandpa patted Li Zheng and said, "Okay, it's a hot day, go back quickly."

"Goodbye, grandpa."

Li Zheng walked all the way home, and when he passed through the building, he was greeted by congratulations from two neighbors, and more neighbors pointed at him from a distance, smiling as brightly as that grandfather.

As for the children following behind, there are also more and more children.

This is a bit too much...

It's just a sports competition, how can it be like winning a Nobel?

I'm afraid it's not like Lao Li just talks to people when he meets them, right?

Hey, this dad can't keep his temper and is too frivolous.

But at this point, Li Zheng had no choice but to go with the flow. In order to encourage the children to learn better, he had no choice but to take the steps of an idol star and move forward resolutely with a halo.

However, as soon as he turned a corner, he could no longer move.

At the door of my unit, parked beside me is a dazzling Princess Pink Beetle.

Two rows of large banners were actually hung on the car body.

[Congratulations to Li Zheng (Unit 3) for winning the physics competition championship! 】

[Brother Li’s car is here, a gift from his best friend Huang Lingqi.]

Li Zheng's eyes suddenly widened, and ten thousand words of Zu An instantly came to his throat, and finally they were condensed into one word.

"grass!"

He finally understood the meaning of those smiles.

Li Zheng ran forward without much thought and tore down the big banner.

But in this way, the aggressive bodywork becomes even more obvious.

The children behind him also opened their mouths.

Especially some girls.

"Brother, this car is so cute. Can I get in and take a ride?"

"Only a princess can ride in such a beautiful car!"

"Then we are all princesses."

"Okay, then brother Li Zheng is also a princess."

As soon as they moved forward, they were greeted by Li Zheng looking back sadly.

"There are no princesses in our country. Princesses are remnants of feudalism."

"The princess is just a tool used by Dituni to make money from you."

"Theoretically, you can only become a princess."

"When you become a princess, you have to go abroad. When you go abroad, you have to take the TOEFL GRE exam. You have to study well."

"Have you done your homework?"

"Don't study yet!"

"Have you studied physics?"

"Don't you want me to teach you in advance?"

"Wow!"

The little girls screamed and dispersed in an instant.

Only the little fat man standing there laughing and laughing at the beginning was left.

"What's so funny?" Li Zheng glared over, "Come here, I'll teach you physics."

"Haha, I know physics, I don't need you to teach me." The little fat man raised his head, he was pretty awesome.

"What is the mechanical formula of Newton's second law?"

"f=ma!"

"Equations of Relativity."

"e=mc2." The little fat man grinned, "Brother, can't you ask something difficult?"

"Okay, okay, be ambitious." Li Zheng said with hooks, "Here's a section on the Navier-Stokes equations."

"Na... na na na?"

"Come on, come on, I'll teach you." Li Zheng opened the bag, took out his notebook, and showed a page.

The little fat man really came over on his bicycle, looked at the densely packed symbols on the small half page of the note, and rubbed his eyes.

Li Zheng then turned to an empty page and handed over the pen: "Have you learned it? Write."

"..."

"Okay, let's read it again." Li Zheng turned it back again, "Let me know if you see it."

The little fat man really tried his best to stare at the pile of things. Half a minute later, he looked up at Li Zheng and twitched his nose: "Brother, I was wrong... I don't know physics..."

"It doesn't matter, I'll teach you." Li Zheng pointed at the notebook and said, "This is the density, this is the dynamic viscosity coefficient..."

The little fat man listened hard, his expression getting worse and worse.

Finally, a tear slipped out.

"Brother, I don't want to learn anymore..."

"Will you still cause trouble in the future?"

"But I didn't cause any trouble..."

"I'm just asking if you are still making trouble?"
