v3 Chapter 2794： Poisoned?

The students who were self-study last night were hiding and watching. The girls babbled, Su Yun attracted the most attention.

They don't care about Fan Tianshui's deterrence. After all, they are still young and don't understand what kind of existence it is. However, there is an adult principal, and they still can see the height of the eyebrows, and dare not provoke the principal at this time.

Fan Tianshui had no tools in his hand. He looked around and broke the alloy inlaid outside the machine for a while. He clamped his fingers with a little force and made a "snap" sound. The metal was as delicate as paper paste. broken.

Principal Ho's eyes flickered. Fortunately, he didn't go to provoke this guy, otherwise it would just be like this ...

What a terrible thing, what a human, a robot.

Fan Tianshui turned into a sharp weapon in Fan Tianshui's hands, like a screwdriver. After a few minutes, the baffle of a juicer with a height of one person was removed.

"Lao Fan, work very sharply." Su Yun praised.

"Well, survival in the wild is one kind, urban survival is another, and they all have to be trained." Fan Tianshui said skillfully disassembling the machine.

"You have a good craft, then why were you so stuck that you couldn't even have appendicitis?" Su Yun asked.

Fan Tianshui smiled and did not answer.

Su Suyun was uncomfortable idle, and did not have the idea of ​​snooping on Fan Tianshui's privacy. Even after asking, it was normal to have no answer.

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

Sure enough, when Fan Tianshui opened the machine, he found that a copper ring with no cover surrounds the doorway. This position of the copper ring keeps the liquid inside it in contact with copper. The process that led to this event was repeated, once again obtaining high concentrations of copper in the beverage solution. (Note 1)

老板 "Boss, it really is. No wonder the orange is okay, it is a problem with the machine. Fortunately, it has been discovered, otherwise students have to be poisoned." Su Yun was relieved after seeing the metal copper ring, and finally found something wrong.

"Well, that's true." Zheng Ren said, glanced at President He, and asked, "Who do you have the final say?"

Principal Ho's heart was irritated.

This is a face-slapping, undisguised face-slapping!

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

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

Zheng Ren's eyes are just a mosaic, who knows who he is.

"Principal He, please take a look and we will leave when we are sure." Zheng Rendao.

Yun Su Yun was constantly taking pictures with his mobile phone while President He looked dignified and asked, "This little comrade, what are you taking ..."

"I'm not telling you, I'm scared to see you. If something goes wrong, I know if I can cover the lid, can I take a little responsibility? I usually don't have to worry about getting the job done." Su Yun said contemptuously. Excellent dissertation material, at least enough for one person to advance. "

"..." Principal He was speechless.

But he bravely looked closer, and sure enough he saw a copper ring appearing in front of him.

"What's going on?" Principal He asked puzzled.

"It is estimated that it is a problem of machine manufacturing, and the sealing is not strict." Su Yundao, "The orange juice from the juice is acidic, and copper is incorporated into the orange juice. Children who drink high concentration of orange juice will naturally be poisoned by copper.

呃 "Uh ... acids ... no, it doesn't mean that the taste is a little acidic, can it be acidic?" The principal He asked in confusion.

"Yes, yes, the pH 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, don't bother to explain it to you, go to the chemistry teacher and ask the biology teacher." Su Yun said scornfully, "The acidity of Coke is basically 2.2, you use Coke to drain the water Do you know? If you have intestinal obstruction in the hospital, you still use Colatron. "

Speaking of the most professional knowledge, Principal He directly slapped. He stared at Su Yun blankly, with a mocking expression on Junlang's face, unable to hide it, and he didn't even want to hide it.

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

"Huh? Can it be removed?"

"Welding dead, just press down." Fan Tianshui said, "I need to do it."

"Okay, I took a picture, and I went down to the city together."

"That's mine ..." The man in the suit almost cried at this time. This machine is his own. Say 掰? !! He just saw what Fan Tianshui had done, and he had no doubt that the big man was shaking himself.

He said only half of what he said and was most covered by an employee.

"Manager, manager, don't beep." The employee was also anxious, and he was not polite to talk. "If they say we are poisoned, I guess you have to be thrown into the bureau."

The man in the suit was dumbfounded and poisoned ... it should not be so serious.

I was struggling. A complete machine had been disassembled by Fan Tianshui. He finally gave me the copper ring ~ www.novelhall.com ~ and gave it to Su Yun.

"Principal He, we are gone." Su Yun said with a smile, "In this case, you find time to talk to the students' parents, the CDC ... Yes, and the Public Security Bureau to explain."

He said, Su Yun picked up his cell phone and started calling Linger.

"That little brother is really handsome." A girl said idiot.

"What are you looking at? That big guy is just so powerful. If you pinch your fingers, the steel bars will break." The boys look at the world differently.

"They're 912?"

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

"I'll ask."

"Dare you catch up?"

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

"Ask me and tell me."

才 "No! That's my little brother."

The noise of the girls soon overwhelmed the little boys' feelings about Fan Tianshui's bravery. Principal He should have shown the dignity of the teacher, but just after Su Yun stunned two sentences, he felt particularly shameless and left in a hurry.

There are a lot of broken things behind the, which dog is in this machine, metal copper is exposed, isn't it harmful?

However, no matter who entered it, it was signed by himself. In the second middle school, President Ho's financial rights and human rights were seized. He could not enter without a tube of ballot pen signed by him.

Wu usually looks prestigious, but at this time, responsibility becomes a big rock, a powder body that accidentally crushes people.

Note 1: A case in the United States that is not familiar with the internal structure of the machine will not be described blindly.
