I have super male syndrome, so it's reasonable that I'm harmless to humans and animals.

Chapter 14: Tutoring Wang Xiaoqiang
The little beast was frightened. He took the paper and stammered:

"Assume... Assume that the function f(x) is differentiable on the closed interval [0, 1]. For... what is this? I don't understand. Mom, help me!!"

When the little guy saw that Su Lin was going to give him extra lessons, he was so happy that he shed tears of excitement.

He even asked his mother to come and study with him.

Su Lin picked up the thick book and hit him on the forehead with it.

"Do it for me. If you keep crying, I'll beat you to death."

Wang Xiaoqiang almost collapsed: "But...but I don't understand it. We didn't learn this in class."

Su Lin grabbed his head and banged it on the table: "Can't you learn it yourself without being taught? Do you want a brain to eat shit?"

Bang bang bang!
Once, twice, three times, soon several big bumps appeared on Wang Xiaoqiang's head.

The little thing was so scared that it kept crying and of course couldn't solve the problem.

Upon hearing the noise, his parents stopped fighting and rushed in.

"Su Lin, you...what are you doing? Let my son go."

Wang Xinmin and Zhang Aiqin said in unison, preparing to rush over to grab their son.

Su Lin pulled out an axe from behind his butt and slammed it on the table with a bang.

The two of them didn't dare to come over, and cried from afar:
"You...you let my son go, we can discuss things."

Su Lin said angrily:

"I gave him extra lessons out of kindness, but you guys didn't appreciate it. Well, if you can solve this problem, I'll let your son go."

finished,

Su Lin threw the piece of white paper in front of the two of them.

Neither of them dared to pick up the paper, they just kept crying and begging Su Lin to let them go.

Su Lin got angry and chopped the table in half with an axe:

"Why, you guys don't give me face when I ask you to do the test? Hurry up and do it!"

The two of them turned pale with fear, and quickly picked up the white paper from the ground and stammered to read the question:
"Assume that the function f(x) is differentiable on the closed interval [0, 1]. For every x on [0, 1], the value of the function f(x) is in the open interval (0, 1), and f'(x) ≠ 1. Prove that there is only one x in (0, 1) such that f(x) = x."

“Look… I don’t understand.”

"What is this? It's both Buddhist and Western."

It seems that they both treat functions as pinyin.

His father seemed to have received some education, and he stammered:
"This...is this a question for the postgraduate entrance examination?"

Su Lin was happy and said, "You have some good eyesight. What do you think? I am very considerate. Although I am staying at your house for a few days, I am also helping your child with his studies, right?"

When the couple heard this, they both cried with excitement:

"But...but this is too early, my son is only in fifth grade."

Su Lin waved his hand: "What I fear most is that my children lose at the starting line. How come you parents don't have any sense of crisis?"

Then another slap was slapped on the little thing's face:
"Why are you daydreaming? Write carefully. If you make a mistake on one question, I'll beat you to death."

"Wow!!!"

Wang Xiaoqiang finally couldn't hold back his overly excited mood and fainted from crying again.

Seeing that he fainted, Su Lin had no fun anymore.

I can only let him go temporarily.

"I'm sleepy. I'll take a nap first and then get up and continue."

finished,

Su Lin went to the living room, picked up his things, found the largest room, closed the door and went to sleep.

As soon as the door closed, I heard the wailing of the couple outside:
"Oh my God, what have we done to deserve such a psychopath?"

You see,
What quality?
Su Lin was a little angry.

I thought to myself, I was helping you cut the fruit with your tutoring with good intentions, but not only did you not appreciate it, you even called me a psycho!

Oh, that’s not right. It seems like I’m really crazy?

That’s okay!

……

After waking up from a good sleep, Su Lin started his tutoring career again.

He pressed the little thing's head and asked him to do the test. However, this time he didn't do the postgraduate entrance examination questions, but randomly picked a fifth-grade English test paper from the side and asked Wang Xiaoqiang to do it.

"Hurry up and do it. If you make a mistake, I'll beat you to death."

The little thing burst into tears of gratitude, and while crying, he stared with his eyes wide open and struggled with the English questions.

The couple were outside sighing and took out their phones several times, ready to call the police.

But I never dared to report it.

Just like Sulin said,

This is a psychopath. Even if we call the police and ask them to take him away,
It might come back in a few days.

I would go crazy at that time.

"It's all your fault. You didn't take good care of your son. Why did you offend such an ancestor when you could have offended anyone else?"

Wang Xinmin complained to his wife in distress.

His wife Zhang Aiqin was not a pushover either, and immediately said:

"How dare you say that to me? Don't you know what kind of person your son is? Who does he follow?"

Wang Xinmin couldn't argue, so he could only change the subject: "What should we do now? This plague... The old man lives in our house, eating and drinking, and even beating his son, ah..."

Zhang Aiqin also looked worried: "That's right, what should we do? He doesn't even pay the rent. Why don't we move?"

Wang Xinmin spread his hands and said, "Move? Where can we move to?"

Su Lin was helping Wang Xiaoqiang with his homework when he heard the word rent.

Yes indeed,

He has now forced his way into the old man's house. If the police really come, he will not be in the right.

No, you have to pay the rent, you have to pay!
"You two, get a rental agreement out, now."

Sulin shouted.

"what?"

Wang Xinmin and Zhang Aiqun didn't understand what Su Lin meant for a moment and were stunned.

"I'm thinking, you can't live here for free, you have to pay rent, how about this, you guys sign a contract and I'll pay you the rent."

The couple were very happy when they heard this, thinking that this living devil finally had a change of heart.

But he said politely: "No, no, if you feel comfortable, you can stay wherever you want."

Su Lin slapped Wang Xiaoqiang in the face while he was doing his homework.

"Damn it, just do it, why are you wasting time talking?"

Wang Xiaoqiang was stunned by the beating and cried, "I... I didn't say anything just now, why are you hitting me?"

Su Lin smiled and said, "You are closest to me, aren't you?"

After that, his expression changed again, "Who told you to stop? Do the questions!"

Bang! Another slap!
Wang Xinmin and Zhang Aiqun were so distressed that they cried and did not dare to offend the moody Su Lin.

So I quickly ran out and printed out two copies of the rental contract.

Of course, the amount and time are both empty.

Su Lin took it, filled in the numbers in the blank space, and quickly asked them to sign and put their fingerprints on it.

When the two of them took it and looked at it, they were dumbfounded.

"One...one dollar for a week??? Is this... possible?"

"Why not?"

Su Lin threw a high rent of one dollar in their faces, raised the axe and asked them to sign quickly in a friendly manner.

Wang Xinmin and Zhang Aiqun looked at the gleaming axe and dared not say a word.

So I quickly signed and sealed the contract.

Su Lin was very happy after getting the contract.

He is also a grateful person.

Therefore, Wang Xiaoqiang was given comprehensive remedial lessons to improve his performance.
