I really don't want to lie down and win

What to worry about.

"How long will it take?" Xu Mang asked curiously, "I still have to buy fruit tea for my fiancee."

"About a day or two."

"How else..." The middle-aged man was actually very afraid of Xu Mang, and silently gave a mutually acceptable situation, saying, "We work in your office, and you can't leave this building. You can't contact anyone, and all communication devices are turned off."

Xu Mang didn't care about it, but Second Grandpa's face was very embarrassed.

quickly,

The so-called restriction began, but before that, Second Grandpa found Xu Mang alone.

"do not worry!"

"It's just a process, give others an explanation." The second grandfather patted Xu Mang's shoulder lightly, and said seriously: "This is a necessary growth in life, you have to learn to accept it, and don't make such mistakes in the future .”

"Oh..."

...

Five p.m,

Yang Xiaoman was still waiting for Xu Mang's fruit tea. He had been waiting for almost three hours. He didn't wait for his own fruit tea, so he got a little angry on the spot. However, when he called him, he was prompted to turn off the phone. He vaguely felt a little strange .

then...

There was obviously something wrong with his demeanor, as if he was a little anxious.

Should something happen?

"Hey?"

"Mom!" Yang Xiaoman called his mother, and said with a worried face, "Xu Mang turned off the phone, and no one can be found."

"what?!"

"He's gone?" Mother Yang asked in surprise, "Don't worry, I'll ask your dad."

"Ok!"

these few minutes,

Yang Xiaoman's seconds seemed like years, and his mind was full of images of what happened to Xu Mang.

the phone rings,

Xiaoman hurriedly picked up the phone.

"Xiaoman!"

"Xiao Xu was interrogated, it's about money." Yang's mother said seriously, "I'll be back tomorrow or the day after tomorrow. Don't worry too much. He's in the physics department building at Fuda now, and he can't get out."

"what?"

"How did this happen?" Yang Xiaoman was taken aback, and said in disbelief, "How did he get involved with money?"

"Humph!"

"Some people think that Xiao Xu is easy to bully, so they just found a reason for money." Yang's mother's tone was full of coldness, and she said indifferently: "And your father is like a normal person, and he said that this is a life experience. Now I think about it." It's going to be hot."

hang up the phone,

Yang Xiaoman was still at a loss, why did this good-looking person go in?

at the same time,

Xu Mang was crossing his legs and drinking Coca-Cola. Looking at the seriousness of the four of them, he felt a little funny.

"Ugh?"

"Be serious, don't make mistakes!" Xu Mang said with a smile.

"..."

"..."

"..."

This guy,

Although it's a procedure, you still pretend to be nervous!

The four of them ignored Xu Mang and continued to do their jobs seriously, but Xu Mang, who was indifferent, could only find something for himself to do.

for example...

Computational feasibility between laser interference and gravitational waves.

however,

As soon as Xu Mang picked up the pen, he encountered a problem. Various theoretical calculation results in the past have proved that the measurement between laser interference and gravitational waves can be achieved, but it cannot be done in reality.

so...

We must change our way of thinking.

finally,

Through how time and space change, the only thing that remains the same is the principle of the speed of light. Xu Mang continuously deduces it from the beginning and uses mathematical language to calculate, but it takes a little time, about three hours.

in fact,

Xu Mang's idea was very simple. He measured the change in the length of light passing through each side. What he did now was to calculate whether the result of measuring the laser as a ruler was the same as measuring the change in the length of light passing through the side himself.

swish swish,

Xu Mang calculated quickly, and then attracted the attention of the four of them.

"???"

"???"

"???"

What is he doing?

Graffiti?
