"I'm sorry for causing trouble to the principal and the school. I will definitely keep a close eye on the students in the future," the head teacher said sincerely.

The investigation continued the next day.

When the police asked about the weekly newspaper, the other party acted as if he was a dead pig that was not afraid of boiling water.

He said he didn't know what happened and refused to admit that he extorted money from his classmates in the bathroom.

Because once he confesses, the Public Security Bureau will give him exquisite handcuffs.

The laws of the Huaxia Empire stipulate that people who are at least fourteen years old but less than eighteen years old and commit crimes shall bear criminal responsibility.

It can be seen from this that age cannot protect crimes, but can only appropriately reduce punishment.

Chu Hai remembered that before the police came, Brother Bao asked someone to contact Brother Qi and asked him to help him. He told him not to tell the truth to the police and that he would never forget Brother Qi's kindness.

Brother Qi readily agreed and expressed his willingness to make friends with Brother Bao.

As for the real reason, Brother Qi didn't want the Public Security Bureau to conduct an in-depth investigation.

Sure enough, when the police found Brother Qi, he said that he was not blackmailing him, but was asking him to borrow money, and there was no grudge between the two parties.

The police were too lazy to ask about this.

From then on, the school had a routine of regularly searching desks.

A reporting box leading directly to the principal's office also appeared.

"Brother Qi, how did you do it?" Chu Hai clearly remembered that he couldn't help but be curious at that time.

Even the police were too lazy to ask about this matter. Chu Hai's intuition told him that it must be related to Brother Qi.

"I took some platinum black from Lao Zeng's lab and mixed it on the weekly school uniforms in advance."

After Brother Qi finished speaking, Chu Hai looked confused. What the hell is Platinum Black?

Fortunately, Brother Qi added: "The towel I threw to him was soaked in methanol."

So...

Chu Hai seemed to understand, but not quite. He took out his cell phone and started searching Baidu.

Baidu explains: When platinum black encounters methanol vapor, it acts as a catalyst, catalyzing the oxidation of methanol, raising the temperature of the platinum powder and easily igniting the methanol.

Chu Hai remembered the fire starter he bought on Taobao, which worked on the same principle. Just blowing on it would make a fire.

It uses the same principle, using platinum wire and platinum black to catalyze the oxidation of methanol vapor, making the platinum wire red hot, and then igniting the methanol.

With shock on his face, Chu Hai shook his head and smiled bitterly. This is what a bully does when he bullies others!

Just a wave of your hand can give your opponent a head-on blow!

I still hope to scare people with a fruit knife, but I am far inferior to Brother Qi.

I have decided that I will pay attention in chemistry class from now on.

"Brother Qi, how does the flame on Zhou Bao continue to burn?" This is also what he is curious about.

"Please open your phone and search carefully for colorless flammable gases. Then guess which one I used. Whether you guess correctly or not is up to you. This secret method cannot be passed on to others."

With his hands behind his back, Chu Hai saw Brother Qi leave with the joy of victory.

Without saying a word, Chu Hai picked up his phone and started checking.

Pure benzene is colorless, transparent and extremely flammable.

Acetone is colorless, transparent and flammable.

Amyl acetate, colorless liquid, flammable.

Octamethylcyclotetrasiloxane is colorless, transparent, odorless and flammable.

…

Brother Qi, please tell me quickly, I can’t guess!

Baidu is a good helper. Chu Hai chased after it anxiously. He really wanted to know the answer.

Those who have never been bullied will never understand the pain of depression.

Chu Hai swore that he really didn't want to learn secretly, but mainly wanted to be a good person who punished evil and promoted good!
