The father and son walked into the office.

Liu Changqing glanced around and found that most of the teachers were present. When they heard the movement at the door, they all turned their heads to look.

The head teacher felt a little embarrassed, and his face turned red.

"You are this person..."

"Which one is the math teacher?"

Liu Changqing interrupted the other party directly without listening to what he was saying, and looked at the people in the room with his head held high.

"..."

No one answered.

Liu Changqing pulled Liu Zhiyue beside him and asked.

"Which one is the math teacher?"

"It's him."

Liu Zhiyue stretched out his hand and pointed at a middle-aged man with a sparse head.

The math teacher, who had his head shrunk and his back was turned, trembled suddenly and then slowly turned around.

A smile formed on his wrinkled face.

"This parent...is there something wrong?"

He had a deep impression on Liu Changqing. The last time he came here, he was not like an ordinary parent. From his perspective, he was the kind of father who protects his calves.

He was also present at Liu Zhiyue's incident, and it was he who raised the doubt that progress was too rapid.

Liu Changqing didn't think much. He moved a stool from the side and placed it next to the math teacher's desk. Then he took out two pieces of A4 paper from the printer not far away and spread them flat on the table.

After doing this, he waved to his son.

"come over."

"Dad...what are you going to do..."

Although Liu Zhiyue was full of doubts, he still walked over and sat down honestly.

The three of them looked at each other.

The math teacher broke the ice.

"This parent..."

"Please give me a question."

"ah?"

The math teacher froze in his seat.

Liu Changqing didn't care about the other person's expression, he glanced at his son.

"What's your math level?"

"I've already studied high school by myself...I'm almost finished."

"Ah!"

The head teacher behind him made a disdainful sound.

Ignoring the other party, Liu Changqing looked at the dumbfounded math teacher.

"Just watch the questions... I'm not asking you to write a whole paper, just ask the big questions."

Pause for a moment.

"Knowledge points in high school should be limited to around the second year of high school. Don't deliberately go overboard. I also went to school."

Although Liu Changqing's tone was very calm when he spoke, for some reason others could clearly feel that he was speaking with anger.

Explosion in silence...

"Okay... what a great kid. He has already studied in high school by himself..."

Without saying much, the math teacher just glanced at Liu Zhiyue and nodded.

He took out a ballpoint pen from the pen holder on the side, pulled out a piece of A4 paper, and then thought for a while.

With more than 20 years of teaching experience, for him, setting questions is just a matter of writing.

The office became quiet for a while.

Liu Changqing stood aside and watched.

The head teacher looked at Liu Changqing, who had his back turned to him. He rolled his eyes first, then turned around and left.

Just took two steps.

"I won't waste your time."

"..."

He turned around and looked at Liu Changqing in surprise, who didn't even look back.

Does this person have eyes on the back of his head?

Liu Changqing continued.

"Wait a minute, I need you to inform me later."

"you!"

"Shh!"

Raising his hand in a gesture of silence, Liu Changqing turned around and looked at her.

"Don't bother asking questions."

"..."

She was extremely angry, which made the head teacher not want to leave. She wanted to see if Liu Zhiyue, who had been a mediocre student in the past, was lying.

Thinking of this, I returned to my desk and sat down.

Time passed minute by minute, and the math teacher was writing something furiously.

Occasionally I pause to think for a moment, and then write again.

Finally it stopped completely.

"Okay, here are these three major questions. If you can solve them, there will be no problem."

Putting down the pen in his hand, the math teacher said.

Liu Changqing reached for the A4 paper and scanned it.

Indeed, it involves some high school knowledge points, but a very small part can be solved even using the formulas learned in junior high school, although it is a bit troublesome.

Although the difficulty is not easy, it is not intentionally too difficult.

Nodding, Liu Changqing placed the A4 paper in front of Liu Zhiyue.

Without saying anything else, after preparing the draft, Liu Zhiyue started writing on the side.

The other teachers in the office didn't say anything, they all looked up.

Liu Zhiyue's thinking is very clear.

This is the conclusion Liu Changqing came to after looking at the formulas listed by his son.

He has always been a smart kid.

This time...Liu Changqing somewhat believed what the other party said last time.

Are you hiding your strength...?

Liu Changqing looked at his son's profile.

His sitting posture is a bit unstandard, and his head feels a bit too low when writing.

But these are not important.

At this moment, Liu Zhiyue's fat face was full of seriousness.

People say that her son looks like his mother, but no matter how he looks at it, Liu Changqing feels that he has a body more like his own.

Especially when looking at it from the side...

I don’t know how long it took, but as Liu Zhiyue put down his pen, everything came to light.

The math teacher was sitting next to him.

This time, it was done in public, and the questions were given on the spot, without any possibility of cheating.

With a look of shock on his face, he reached out and grabbed the A4 paper in front of Liu Zhiyue.

Looked up.

Time passes minute by minute.
