The students who went to the evening self-study all hid aside and watched, and the girl chattered, and Su Yun attracted the most attention.

They didn't care about Fan Tianshui's intimidation. After all, they were still young and didn't understand what kind of existence it was. But with the principal, they could see more or less that they were looking at it and did not dare to provoke the principal at this time.

Fan Tianshui had no tools in his hand. He looked at it, broke apart the alloy embedded outside the machine, clamped his fingers on it, and used a slight force, and a "pop" sound, and the metal broke gently like paper paste.

Principal He's eyes twitched. Fortunately, he didn't provoke this guy, otherwise he would have just been...

It's so frightening. This is not a human, it's a robot.

The broken metal piece turned into a sharp weapon in Fan Tianshui's hands, like a screwdriver. After a few minutes, the baffle of the juicer that was more than one person tall was removed.

"Old Fan, the work is very good." Su Yun praised.

"Well, survival in the wild is one kind, and survival in the urban is another kind, and we all need to be trained." Fan Tianshui said skillfully as he dismantled the machine.

"You have good skills, so why are you so distressed that you can't even have appendicitis?" Su Yun asked.

Fan Tianshui smiled and did not answer.

Su Yun was idle and uncomfortable, and did not have the idea of ​​spying on Fan Tianshui. Even after asking, it would be normal to have no answer.

Zheng Ren did not pay attention to Fan Tianshui's skills. He was concerned about whether there was copper inside exposed outside.

Sure enough, when Fan Tianshui opened the machine, he found that there was a shielded copper ring surrounding the doorway. The position of the copper ring made the liquid contained in the interior contact copper continuously. The process of manufacturing caused this event was repeated, and high concentration of copper was obtained in the beverage solution again. (Note 1)

"Boss, it's true. No wonder Orange is fine, it's a problem with the machine. Fortunately, I found it, otherwise some students would have to be poisoned." Su Yun breathed a sigh of relief after seeing the metal copper ring, and finally found something wrong.

"Well, that's true." Zheng Ren said, glanced at Principal He and asked, "Who has the final say here?"

Principal He was embarrassed and angry.

This is a slap in the face, an unconcealed slap in the face!

I clearly saw him at noon, but he pretended not to know him. Even the Nobel Prize winner could not be so arrogant.

"Boss, that's the principal of No. 2 Middle School. His surname is He. I saw it at noon." Su Yun sighed and said helplessly.

Zheng Ren's eyes were just mosaics, who knew who he was.

"Principal He, take a look and we will leave after we are sure." Zheng Ren said.

Su Yun kept taking pictures with his mobile phone. Principal He looked solemn and asked, "This little comrade, you are taking pictures..."

"I'm not suing you, it's a sign that I'll scare you. If something happens, I'll know whether I can cover myself. I can take some responsibility. I don't have to worry about doing my job well." Su Yun said contemptuously, "This is an excellent paper material, at least enough for one person to advance."

"..." Principal He was speechless.

However, he plucked up the courage to look closer and saw a piece of copper ring appearing in front of him.

"What's going on?" Principal He asked in confusion.

"It is probably a problem of machine manufacturing, and it is not tightly sealed." Su Yun said, "The orange juice squeezed is an acidic substance. With copper being mixed with orange juice, the children will naturally get poisoned by copper after drinking high concentrations of orange juice."

"Uh... acidic substance... no, it's just a bit sour in taste. Can it be an acidic substance?" Principal He asked in confusion.

"Well, yes, the pH value of orange juice is about 2-3, and the pH is enough."

"Impossible! The pH value of hydrochloric acid is 2!" Principal He did not believe this statement at all.

"You... forget it, I'm too lazy to explain to you. Go to the chemistry teacher and then ask the biology teacher." Su Yun said contemptuously, "The acidity of Coke is basically 2.2. Do you know that using Coke to pass the sewer? In some intestinal obstructions in the hospital, Coke is also used."

Speaking of the most professional knowledge, Principal He was stunned. He looked at Su Yun in a daze, his handsome face filled with a mocking expression, and he could not hide it, and he didn't want to hide it at all.

"Brother Yun, do you need to remove it and send it to inspection?" Fan Tianshui asked.

"Hmm? Can it be removed?"

"Weld it to death, just break it down." Fan Tianshuidao, "If you need it, I will do it."

"Okay, I'll leave a photo, break it down and send it to the city."

"That's mine..." The man in the suit was almost crying at this time. The machine was his own, so he could just stop it?! He saw what Fan Tianshui did just now, and he had no doubt that this big guy was shaking himself.

But only half of what he said was covered by an employee.

"Manager, manager, don't whine." The employee was anxious and said politely, "If they say we're poisoning, I guess you'll have to be thrown into the bureau."

The man in the suit was stunned and poisoned... Such a serious crime should not be so serious.

Just as he struggled, a complete machine had been dismantled by Fan Tianshui. He finally broke off the copper ring and handed it to Su Yun.

"Principal He, we're leaving." Su Yun said with a smile, "For this matter, you find time to go to the students' parents, the Center for Disease Control and Prevention... By the way, there is also a public security bureau to explain."

As he said that, Su Yun picked up his cell phone and started to call Linger.

"That little brother is so handsome." A girl said in a silly way.

"What are you looking at? That big guy is so powerful. With a clamp of his fingers, the steel bars will break." The boys have different perspectives on the world.

"Are they from 912?"

"It seems that the little brother is really handsome. I don't know what his name is."

"I'll go and ask."

"Dare you dare to chase after me?"

"I know the aunt in the cafeteria and said they went to the cafeteria in the afternoon."

"Tell me out after asking."

"No! That's my little brother."

The noise of the girls quickly drowned the boys' feelings towards Fan Tianshui's bravery. Principal He should have shown his dignity in his master's teachings, but he just said a few words from Su Yun that he felt very embarrassed, so he had to leave in a hurry.

There are a lot of troubles behind it. Which one did this machine come in? The metal copper is exposed. Isn’t this harmful?

However, no matter who entered, they signed the letters themselves. In No. 2 Middle School, Principal He seized financial and human rights, and he could not get in without him signing atomic pen.

It usually looks majestic, but at this time the responsibility becomes a big stone, and if you accidentally crush someone to pieces.
