I kidnapped an alien civilization

Li Mo saw Zhang Xiaoli nodded again with certainty.

He stepped forward, took a deep breath, and gently placed the measuring cup on the stage of the precision weighing instrument.

"399.96g!"

A row of numbers jumped out on the LCD screen of the weighing instrument.

"Me!" Li Mo can't describe his shock now that there is such a precise technique in the world.

When he was a child, he also heard the story of an oil seller dripping oil through a copper coin. The oil seller in the story was able to pass sesame oil through the copper coin hole without spilling because of his practice. But the scene in front of her was not, because the measuring cup and the sulfuric acid bottle were selected temporarily, and Zhang Xiaoli had no chance to "preview" in advance.

"This... big sister." Liu Mingrui, the boss of the pouch trio, had a smile on his face, and asked obediently, "Can you tell me how you did it?" , The pouch trio can always be ashamed to ask, for them, chemical laboratory operations are neither knowledge nor technology, but a kind of art.

"Feeling." Zhang Xiaoli frowned and thought for a while, then gave an unacceptable reason.

"Feeling." There was a strange expression on Liu Mingrui's face, he stretched out his hand to look at it, and then sighed heavily.

"Boss, I don't think there is any need to compare. This little girl's talent is fully qualified to join our laboratory."

Li Mo understood what he meant. Different from other laboratories, the Yanjing Mozi Science and Technology Laboratory focuses on the talent of its employees. Compared with the knowledge that can be learned the day after tomorrow, the talent is unique.

"Really, can I really join the lab?" Zhang Xiaoli shouted happily.

Li Mo nodded. With the affirmation of the pouch trio, she already has the qualification to join the laboratory.

With the smile still on her face, Zhang Xiaoli suddenly said seriously: "But I still want to finish the game with you."

even more than? Li Mo is a bit confused about her persistence, is it another laboratory weirdo?

At this moment, a serious expression appeared on the faces of the three brothers with puffy eyes. If the competition just now was just a test for the little girl, what follows is a torture of their skills.

"Very good, what's the next item?" Liu Mingrui asked. If they avoided the competition today, perhaps the story of the escaped trio would be circulated on the Yanda campus from now on.

"The second item is the speed test. You need to separate two randomly mixed liquids. The fastest player wins." Li Mo said helplessly, these scientific research dogs always have a stubbornness that is different from ordinary people.

"I'll come this time." The third brother Liu Xuanchen stood up.

Li Mo randomly selected two reagents from the reagent cabinet in the way of "ordering soldiers and ordering generals", and then mixed them together.

Twenty minutes later, the third brother Liu Xuanchen saw Zhang Xiaoli, who had completed the separation, standing beside him with a smile on his face, with a frustrated expression on his face. He lost this round, but he didn't stop what he was doing because he never allowed himself to interrupt the experiment. After 2 minutes, he also completed the separation.

"Boss, what is the next competition?" Zhang Xiaoli seemed to regard herself as a member of the laboratory.

Looking at the trio with bags under their eyes, Li Mo could only say helplessly: "The last item is tertiary butyllithium."

"Participants from both sides need to independently use tert-butyllithium to produce trialkyl boron hydride files."

"tert-butyllithium?"

"tertiary butyllithium!"

The dejected trio with bags under the eyes and the confident Zhang Xiaoli all took a step back, Li Mo smiled slightly, this is what he wanted. Chemistry is a kind of scientific exploration, and scientific exploration is always full of various surprises. As a real experimenter, one day you will encounter dangerous chemicals in your experiments.

Alfred Bernhard Nobel is a well-known chemist, the name of the Nobel Prize that is popular all over the world. His greatest achievement is the invention of nitroglycerin explosives, which can be used in the process of studying explosives In the movie, the factory was blown up by an accidental explosion, and his younger brother was killed.

Similar accidents emerge in endlessly in the chemical world, especially when operating some flammable and explosive chemical reagents, it requires the boldness and care of the experimenter. For when a man's mind is controlled by fear, he is not far from error.

Tert-butyllithium is an extremely dangerous organometallic compound. It is highly flammable and can even ignite spontaneously in the air. It must be protected with dry nitrogen during storage and must be isolated from oxygen during use.

Because of its flammable properties, it was once hailed as a laboratory killer, and many experimenters turned pale when they heard of it. Later, with the improvement of protection methods in modern laboratories and the invention of inert gas protection devices, this situation was alleviated, but it is still a chemical material that many experimenters are unwilling to use.

"Boss, have you purchased insurance for us?" The boss of the baggy trio raised his hand and asked from the bottom of his heart: This is just a small competition, don't we need to use big weapons?

Li Mo waved his hand and said angrily: "Don't worry, the insurance of 5 million per person is enough to change the skin of your whole body once."

"Then what about me?" Zhang Xiaoli also raised her hand timidly and asked.

"You have it too. There are insurance clauses in the contract you signed as an intern. Didn't you read it carefully?" Li Mo replied. He would choose to prevent any accidents before they happen. Naturally, he would not delay the employee's commercial insurance. Down.

Li Mo and the pouch brothers stood outside the laboratory, looking at the situation inside through the glass. His palm lightly rested on a red button, which was the control button for controlling the fire protection facilities.

Liu Mingrui and Zhang Xiaoli had already put on biochemical protective suits, and they looked out the window and waved.

".Is this a farewell?" Li Mo thinks that in the future, we still need to use some dangerous reagents frequently. Even if we don't have the opportunity to use them, we must create opportunities, or we can engage in such "dangerous activities" once a week, otherwise these experimenters will The courage is getting smaller and smaller. He thought it was much better than a horror movie.

The two brothers with pouches who were also outside the window found a hint of danger from the strange smile on his face. They looked at each other and quietly walked away a few steps.

Bake the bottle, weigh the raw materials, insert the thermometer, replace with argon, put the condensed water on, put the bottle in industrial ethanol, plug the flask and flush it with nitrogen, and cool to -78°C.

Then take out the constant pressure nitrogen pumped by the syringe.

This is a normal experimental step, skipping any step will make the experiment uncontrollable.

The two people in the laboratory operated separately, and Li Mo kept a close eye on the steps they were carrying out. Once he found that someone missed any step, he would terminate the experiment. After all, he didn't want to turn the laboratory into a flaming mountain.

The liquid nitrogen had already been poured, and the previous actions of the two were almost synchronized. This dangerous experiment focused on the accuracy of the steps.

But Li Mo found that Zhang Xiaoli had finished extracting nitrogen 1 second faster than Liu Mingrui, so he recalled it with a frown.

"Stop!" Li Mo shouted into the pager.

Zhang Xiaoli, who was about to open the refrigerator, stopped and looked out the window suspiciously.

"How many times has your syringe pumped nitrogen?" Li Mo asked.

"One time, is it enough to draw the full amount?" Zhang Xiaoli replied quite naturally.

Li Mo shook his head when he heard the words, "At least three times, you need to smoke again!"

Through this detail, he already knew that the girl had never actually operated the experiment of tert-butyllithium, although she copied all the previous steps from the book, and there was nothing wrong. But this small detail that was not in the textbook still betrayed her.

If the syringe is in perfect condition, it is true that only one pumping of nitrogen is enough to ensure that no oxygen remains in the needle, but as an industrial syringe, it is difficult to have a perfect physique. Maybe there will be tiny potholes on the inner wall of the glass, so that one extraction can't completely remove the oxygen.

Li Mo explained patiently, and Zhang Xiaoli suddenly realized.
