Chapter 2793 Poisoning? (Master Qingfeng Zhuying Jiageng)

The students who were self-study last night all hid aside and watched, the girls chattered, and Su Yun attracted the most attention.

They didn't care about Fan Tianshui's threat. After all, they were still young and didn't know what kind of existence it was. But with the headmaster around, they could more or less tell the difference between their eyebrows and eyebrows, and they didn't dare to provoke the headmaster at this time.

Fan Tianshui didn't have a tool in his hand, so he looked around, broke off a section of the alloy inlaid on the outside of the machine, clamped his fingers on it, exerted a little force, and there was a soft "pop", the metal was as light and delicate as if it was made of paper. broken.

The corners of Principal He's eyes twitched. Fortunately, he didn't provoke this guy, or else it would be like this all of a sudden...

It's really scary, this is not a human, it is a robot.

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

"Old Fan, the work is quite neat." Su Yun praised.

"Well, survival in the wild is one kind, and urban survival is another, both of which require training." Fan Tianshui said as he skillfully disassembled the machine.

"You have good skills, so why were you so sleepy that you couldn't even treat appendicitis?" Su Yun asked.

Fan Tianshui chuckled and didn't answer.

Su Yun felt uncomfortable just because he was idle, and he didn't want to pry into Fan Tianshui's privacy. It's perfectly normal for him not to have an answer.

Zheng Ren didn't pay attention to Fan Tianshui's skills, what he cared about was whether there was copper exposed inside.

Sure enough, when Fan Tianshui turned on the machine, he found that there was an unshielded copper ring surrounding the doorway. This position of the copper ring made the liquid inside contact the copper continuously. Repeat the manufacturing process leading to this event, again to obtain high concentrations of copper in the drink solution. (Note 1)

"Boss, that's really the case. No wonder the orange is fine, it's a problem with the machine. Fortunately, it was discovered, otherwise some students would have been poisoned." Su Yun was relieved when he saw the metal copper ring, and finally found out what was wrong.

"Well, that's true." Zheng Ren said, glanced at Principal He, and asked, "Who is in charge here?"

Principal He felt ashamed and angry.

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

I clearly met him at noon, but he pretended not to know him. Even a Nobel Prize winner can't be so arrogant.

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

Zheng Ren's eyes were just pieces of mosaic, who knew who he was.

"Principal He, take a look and we'll leave after we're sure," Zheng Ren said.

Su Yun was constantly taking pictures with his mobile phone. Principal He asked with a serious face, "Little comrade, what are you taking pictures of..."

"I'm not suing you, I think it scares you. If something goes wrong, you know how to cover it up. Can you be a little bit responsible, and you don't have to worry about it if you usually do your job well." Su Yun said contemptuously, "This is an article Excellent thesis materials, at least enough for one person to advance."

"..." Principal He was speechless.

But he had the courage to look closer, and he saw a section of copper ring appearing in front of him.

"What's going on here?" Principal He asked suspiciously.

"It's probably a problem with the manufacturing of the machine, and the airtightness is not tight." Su Yun said, "The orange juice squeezed out is acidic, and copper is incorporated into the orange juice. Children will naturally be poisoned by copper after drinking high-concentration orange juice."

"Uh... Acidic substances... No way, isn't it just that the taste is a bit sour, could it be acidic substances?" Principal He asked suspiciously.

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

"Impossible! The ph value of hydrochloric acid is 2!" Principal He didn't believe this statement at all.

"You...forget it, I'm too lazy to explain to you, go to the chemistry teacher and ask the biology teacher." Su Yun said contemptuously, "The acidity of cola is basically 2.2. You can use cola to sewer. Do you know? In the hospital, some patients with intestinal obstruction still use Coloton.”

When it comes to the most professional knowledge, Principal He is immediately dumbfounded. He looked at Su Yun blankly, with a mocking expression on his handsome face, which he couldn't hide, and he didn't want to hide it at all.

"Brother Yun, do you need to dismantle it for inspection?" Fan Tianshui asked.

"Huh? Can it be removed?"

"It's welded, just break it off." Fan Tianshui said, "I'll do it if necessary."

"Okay, I'll keep the photo, break it off and send it to the city together."

"That's mine..." The man in the suit was about to cry at this moment, this machine is his own, so you can break it if you say so? ! He saw what Fan Tianshui did just now, and he had no doubt that this big man was shaking him.

But he only spoke half of the words, and was finally covered by an employee.

"Manager, manager, please don't beep." The employee was also anxious, and his words were not polite, "If they say we poisoned you, I guess you will be thrown into the bureau."

The man in the suit was dumbfounded, poisoning... Such a serious crime should not be possible.

While struggling, Fan Tianshui disassembled a complete machine. He finally broke off the copper ring and handed it to Su Yun.

"Principal He, let's go." Su Yun said with a smile, "You should find time to explain this to the students' parents, the CDC...by the way, and the Public Security Bureau."

With that said, Su Yun picked up the phone and started calling Ringer.

"That little brother is really handsome." A girl said in a nympho.

"What are you looking at? That big guy is powerful. When he pinches his fingers, the steel bar snaps." Boys see the world from a different angle.

"Are they from 912?"

"It seems to be, that little brother is really handsome, I don't know his name."

"I'll ask."

"Do you dare to catch up?"

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

"Ask and tell me."

"No! That's my little brother."

The noise of the girls quickly drowned out the young boys' feelings for Fan Tianshui's bravery. Principal He should have shown the dignity of a teacher, but just now he felt very humiliated by Su Yun's words, so he had to leave in a hurry.

There are still a lot of broken things in the back. Who the hell bought this machine, and the metal copper is exposed. Isn't this harmful!

But no matter who entered, it was signed by himself. In No. 2 Middle School, Principal He was caught by the financial and human rights. Without his signature, even a ballpoint pen could not enter.

Usually it looks majestic, but at this time, the responsibility becomes a big rock, and if one is not careful, it will crush people to pieces.

Note 1: A case in the United States. I am not familiar with the internal structure of the machine, so I will not describe it blindly.
