The students who were studying in the evening were hiding and watching. The girls were chattering, 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 here, they could still more or less see the difference between their eyebrows and their eyebrows, so they didn't dare to provoke the principal at this time.
Fan Tianshui didn't have any tools at hand. He looked at it and broke off a section of the alloy embedded in the machine. He clamped it with his fingers and applied a slight force. There was a soft "pop" sound, and the metal seemed to be made of paper. It was as light and delicate as paper. broken.
Principal He's eyes twitched when he saw it. Fortunately, he didn't provoke this guy, otherwise he would just...
It's really scary. This is not a human, it's a robot.
The broken piece of metal turned into a sharp tool in Fan Tianshui's hands, like a screwdriver. In a few minutes, he removed the baffle of the juicer, which was as tall as a person.
"Old Fan, you did your job very neatly." Su Yun praised.
"Well, survival in the wild is one kind, and survival in the city is another, and both require training." Fan Tianshui said as he skillfully dismantled the machine.
"You are good at your craft, so why were you so trapped that you couldn't even treat appendicitis?" Su Yun asked.
Fan Tianshui chuckled and didn't answer.
Su Yun was just idle and feeling uncomfortable, and had no intention of prying into Fan Tianshui's privacy. It was normal for him to leave it alone after asking and not having an answer.
Zheng Ren didn't pay attention to Fan Tianshui's skills. He was concerned about whether there was any copper exposed inside.
Sure enough, when Fan Tianshui opened the machine, he found that there was an unprotected copper ring surrounding the doorway. The position of the copper ring caused the liquid inside to constantly contact the copper. Repeating the manufacturing process that led to this event again resulted in high concentrations of copper in the beverage solution. (Note 1)
"Boss, it's true. No wonder Cheng Zi is fine, it's a problem with the machine. Fortunately, it was discovered, otherwise a student would have been poisoned." Su Yun breathed a sigh of relief after seeing the metal copper ring, and finally found what was wrong.
"Well, that's true." Zheng Ren said, glanced at Principal He, and asked, "Who among you has the final say?"
Principal He felt ashamed and angry.
This is a slap in the face, an unabashed slap in the face!
I had clearly seen him at noon, but he pretended not to know him. Even a Nobel Prize winner couldn'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, please come and take a look. Once you're sure, we'll leave." Zheng Ren said.
Su Yun kept taking pictures with his mobile phone. Principal He looked solemn and asked, "Little comrade, are you taking pictures..."
"I'm not suing you, I think I scared you. If something happens, you will know how to cover up. Can you be a little responsible? You don't have to worry about doing your job well." Su Yun said disdainfully, "This is an article Excellent thesis materials, at least enough for one person to be promoted.”
"..." Principal He was speechless.
But he braved it and looked closer, and sure enough he saw a piece of copper ring appearing in front of him.
"What's going on?" Principal He asked doubtfully.
"It's probably a problem with the machine, and the sealing is not tight." Su Yundao said, "The orange juice that comes out of the juice is an acidic substance, and copper is incorporated into the orange juice. Children who drink high-concentration orange juice will naturally suffer from copper poisoning."
"Uh... acidic substances... no, it just tastes a bit sour, could it be acidic?" Principal He asked doubtfully.
"Well, yes, the pH value of orange juice is about 2-3, which is enough pH."
"Impossible! The pH value of hydrochloric acid is only 2!" Principal He didn't believe this statement at all.
"You... forget it, I'm too lazy to explain to you, go ask the chemistry teacher, and then ask the biology teacher." Su Yun said contemptuously, "The acidity of Coke is basically 2.2. You know that you can use Coke to connect to the sewer. What? If someone has intestinal obstruction in the hospital, they still use Cloton."
Speaking of the most professional knowledge, Principal He was immediately confused. He looked at Su Yun blankly, his handsome face filled with a mocking expression that he couldn't hide, and he didn't even want to hide it.
"Brother Yun, do you need to dismantle it and send it for inspection?" Fan Tianshui asked.
"Huh? Can it be removed?"
"It's welded together, just break it off." Fan Tianshui said, "I'll do it if necessary."
"Okay, I'll keep the photo, break it off and take it to the city together."
"That's mine..." The man in the suit was almost crying at this time. This machine is his, so he can just say goodbye? ! He saw everything Fan Tianshui did just now, and he had no doubt that this big man was flirting with him.
But he only said half of what he said before he was muffled by an employee.
"Manager, manager, please don't beep." The employee was also anxious and spoke rudely, "If they say we poisoned you, I guess you will be thrown into the police station."
The man in the suit was dumbfounded, poisoning... It shouldn't be such a serious crime.
During the struggle, a complete machine had been disassembled by Fan Tianshui. 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 matter to the students' parents, the Centers for Disease Control and Prevention... and, by the way, the Public Security Bureau."
With that said, Su Yun picked up the phone and started dialing Lin Ge's number.
"That little brother is so handsome." A girl said in a coquettish way.
"What are you looking at? That big guy is so powerful. He pinched his fingers and the steel bar snapped." Boys see the world from a different perspective.
"Are they from 912?"
"It seems, that little brother is really handsome, I don't know his name."
"I'll ask."
"You dare to catch up?"
"I know the aunt in the cafeteria. She said they went to the cafeteria in the afternoon."
"Ask and tell me."
"No! That's my little brother."
The girls' noise soon drowned out the boys' feelings for Fan Tianshui's bravery. Principal He was supposed to show his dignity as a teacher, but he had just been scolded by Su Yun and felt that it was very shameful, so he had to leave in a hurry.
There are a lot of messy things behind it. Who the hell entered this machine? The metal copper is exposed. Isn’t this harmful
However, no matter who entered, they all signed it themselves. In the No. 2 Middle School, Principal He was so focused on financial and human rights that no ball pen could enter without his signature.
Normally, he looks majestic, but at this time, responsibility becomes a big stone, and if he is not careful, he will crush the person to pieces.
Note 1: A case in the United States. If you are not familiar with the internal structure of the machine, I will not describe it blindly.
