Chloroform, also known as chloroform, is a colorless hyaluronic liquid, which is highly volatile, has a special odor, and needs to be stored in a brown reagent bottle. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Chloroform is not easy to burn, but under the action of light, it can be oxidized by oxygen in the air to hydrogen chloride and highly toxic phosgene.

And now, with plenty of light and oxygen, chloroform is flying in the air.

Yang Tian stretched out his hand to Han Bing and turned around, scooped up the brown reagent bottle containing chloroform on his experimental table, quickly plucked the dropper covered on it with his fingers, and pushed it backwards along the route of the colorless liquid in the air.

The slow-motion vision made Yang Tian's hand more stable, and he perfectly accepted all the leaking liquid without a drop.

At the same time, he moved backwards, and the same hand grabbed the other reagent bottle accurately before hitting the ground.

"Click!"

The sound of the dropper being pulled out just now inserted into the other reagent bottle.

"Bang!"

The crunch of two reagent bottles colliding.

"Boom!"

The muffled sound of the test solution swirling in the bottle.

The next moment-

"Ahh

The girl's scream had just sounded, the buzz in her ears was instantly covered, and the slow motion instantly accelerated to a normal speed, and Yang Tian froze in place.

A feeling of dizziness came, and Yang Tian actually had a sense of motion sickness on the ground for a while.

"Are you alright?"

Han Bing's voice.

Yang Tian turned his head and saw the rare relationship in Han Bing's eyes, revealing a hint of a smile.

The feeling of dizziness came and went quickly, and Yang Tian had already adapted to the normal speed, took the two reagent bottles, and got up.

"Ahhh

The girl with the ponytail was still screaming, and when she looked at Yang Tian, her voice suddenly seemed to be stuck in her throat, and she looked surprised.

"You...... I caught it! ”

The girl with long hair and a big wavy shawl next to her stammered, her eyes were round, her fingers were subconsciously forced, and the rubber head of the dropper in her hand was retracted, and a stream of colorless liquid squirted out.

Yang Tian lifted his hand and directly put the reagent bottle that was not covered by a dropper.

"Click!"

The dropper is tightly closed to the reagent bottle, so that not a single drop of excess liquid leaks out.

"What are you doing! How can you be so careless! ”

Zhong Zheng finally came late, looked around, and found that there was not a drop of liquid spilled, and couldn't help but glance at Yang Tian in surprise.

Yang Tian didn't speak, frowned and put one of the reagent bottles in his hand on the back table, and the other put back on his experimental table, looking at Han Bing, "You weren't splashed, were you?" This thing is poisonous. ”

"Nope." Han Bing shook his head.

Of course, she wasn't splashed, and the liquid was loaded back by Yang Tian before it reached her door.

Zhong Zheng was sternly reprimanding the two girls at the back table, Yang Tian squinted his eyes and looked at the two.

The dropper is in the hands of the long-haired and wavy ones, the reagent bottle is in the hands of the ponytail girl, there are no cockroaches or rats in the laboratory, why did she take off the reagents in her hands?

……

After the precipitation, DNA was extracted, various measurements were performed, and by the way, a gel electrophoresis was done, and the experiment was finally over.

"I have given the template of the experiment report to the class representative, and the report must be submitted at the designated website within 48 hours from now on.

Finally getting rid of Zhong's formal class, almost all the students felt a sense of relief.

The academician is indeed an academician, and this aura is simply terrifying! After a class, they were all trembling, for fear that if something was wrong, they would be scolded by Zhong Zheng.

The two girls sitting behind Yang Tian and Han Bing were even more so, because of the fact that they splashed chloroform out, they were carefully taught half a lesson by Zhong Chengzai.

But Yang Tian felt that they should.

That's chloroform, which produces a highly toxic substance with a little action! Or came out of his hands in that impossible situation!

Just like Zhong said before the official class, they will all be doctors in the future, and there is a life between raising their feet and waving their hands, and Yang Tian really sweated for the patients who fell into the hands of these two girls in the future.

Yang Tian suddenly began to like this more serious old man, and medical workers should have such a rigorous and calculating attitude.

The students quickly took off their white coats, packed their schoolbags and left, but Yang Tian was not in a hurry, slowly packed up the laboratory table, returned various reagents to their original positions, and found a rag to wipe the table.

This is the point that he feels the most in the system in addition to the specific experimental operation skills - the aftermath!

In order to finish the experiment and not deal with the aftermath, he was repeatedly electrocuted by the system five or six times.

Not only some reagents will be toxic, but those non-toxic reagent residues may also have an unexpected reaction with the reagent used in the next experiment.

After all, the next group of people didn't know what kind of experiment Yang Tian had done this morning, and what kind of reagent was left on the table.

If the aftermath is not properly addressed, the consequences cannot be predicted.

Of course, Han Bing has been sent away by him, and this matter can be done by a man.

After tidying up his desk and taking a look at the laboratory, Yang Tian sighed leisurely.

Quality, where is the quality? Will you die if you clean up the endgame before leaving?

Yang Tian is not a saint, but it is not a matter for him to watch such a big mess, in case anyone suffers from it, who is on the head of this matter?

There are gods in the head, this is not necessarily superstition, after all, even such a mysterious thing as the system has come out, and it is possible to have another immortal.

There were only two people left in the entire laboratory, Yang Tian buried his head in a humming and humming, and Zhong officially clicked on the podium.

"Knock knock!"

"Knock knock!"

There was a knock on the ajar door of the lab.

"May I come in?"

A figure flashed in, and Yang Tian glanced up, it was Jiang Yuan.

What is Jiang Yuan doing here? This is not his classroom.

Yang Tian was stunned for a moment, but soon understood that he was coming for Zhong.

Jiang Yuan was also stunned, he deliberately waited outside the door for a long time before coming in, but he didn't expect Yang Tian to leave yet.

However, he didn't care too much, as soon as he saw Yang Tian wiping the table with a rag, he knew that nine times out of ten he was the student on duty who was left to clean.

"Hello Mr. Zhong." Jiang Yuan walked to Zhong Zheng's side.

"Huh? Looking for me? Zhong officially turned his head, glanced at Yang Tian first, and then looked at Jiang Yuan, his eyes narrowed slightly, not knowing what he was thinking.

"I sent you an email in English yesterday afternoon, my name is Jiang Yuan." Jiang Yuan had a decent smile on his face, and he didn't know whether it was intentional or unintentional, and the word "English" was emphasized.

"Oh." Zhong officially responded, frowning slightly, and continued to look at the computer screen.

Jiang Yuan's face stiffened for a moment, but he quickly regained his composure.

"I don't think you may have seen my email yet, yes, I ......"

Zhong Cheng suddenly raised his hand and interrupted Jiang Yuan's words, "Pleasehelpmecollecttheboxwiththepipettetipsandputtheminthebasket."
