Call the Beast, what about your morals?

Richard was very hungry at the moment. He had only eaten a few mouthfuls of steamed buns last night before he was hooked into bed by Mistress Sun. If this continues, I will definitely faint.

People who passed by Richard carefully avoided him, for fear that if he accidentally fell on him, wouldn't they be extorted some money?I'm still a foreigner, and I don't know how to make myself look like this. Is it a smuggling?

Passers-by are all alone, occasionally stopping to take a photo with their mobile phones.

Richard didn't stop taking pictures. If these people posted the photos on the Internet, the chances of their own people finding him would be even greater.

Richard was in the downtown area at this time, and finally a few little girls saw that Richard was pitiful, and specially gave him two hamburgers and a bucket of milk tea—after all, Richard’s face was placed here, and at this time It seems that there is a bit more taste of a down-and-out noble son.

Richard didn't feel embarrassed either, watching a few girls gather together and finally gave him the food in broken English, Richard thanked him with a tired smile, and went on When I came over, I sat at the outdoor coffee table by the roadside and ate.

A few girls took a few photos with their mobile phones in embarrassment, and said goodbye to Richard.

Richard nodded with a smile, watched them leave, and swallowed the food in his mouth as quickly as possible.

Where there is a lot of traffic, the other party can't do it, but it doesn't mean that you are safe.

Richard swallowed the last mouthful of food with milk tea, looked at the man in black standing at the alley opposite the square, blinked, got up and dragged his bleeding leg into the shopping mall.

Richard's trouser legs were covered in blood, but the mall was so crowded that no one noticed.

Seeing that Richard saw him and turned around and entered the mall, Erhei slowly took out his mobile phone and talked to the people inside, then pushed his sunglasses, put on fingerless gloves, and swaggered with his love gun and went in.

Ever since he knew that there was a fat guy who published a book called What Notes, and there was a character in it who looked very similar to him, and since he was asked by several girls to take a picture two years ago, Erhei no longer had to worry about what to do. Where do you disassemble and stuff your favorite gun...

It's really a joyful thing.The eyes behind Er Hei's sunglasses were bent with a smile, and he smiled brightly at the girls who took pictures of him, and entered the mall.

There is still a difference between a real gun and a prop gun, but because it happens to be a Sunday, there happens to be a small comic exhibition on the third floor of the shopping mall, and the security guards also treat it as a black man who is here to attend, so he casually glances at it and lets it go.

Erhei was still walking slowly here, when he suddenly heard a cry of exclamation in front of him, the crowd crowded forward together, Erhei squinted his eyes, squeezed through the crowd and walked quickly towards the gathering point with a gun in his hand.

Ai Gong shook her wrist lightly, staring at the display of the analytical balance, and shook the medicine on the medicine spoon onto the weighing paper.

"78 mg...passed!" Ai Gong saw the reading quickly approaching 78 mg, and stopped shaking immediately, but it still passed.

"How much?" Ai Guichu was looking for the liquid medicine to use in the refrigerator where the medicine was stored, and asked when she heard Ai Gong's voice.

"0.0883 grams..." Ai Gong said weakly.

"It's beyond the margin of error, try again." Ai Gui didn't raise her head.

Ai Gong sighed, poured the medicine on the weighing paper back into the bottle, and muttered: "This is the fourth time, I weighed it four times..."

The teaching experiments that Ai Gong does on weekdays are often more than ten grams, at least 0.1 grams, and she has never done milligram-level reactions, so now when weighing these substances, they accidentally exceed more than ten milligrams.

Carefully shake off the medicine, and finally weighed 0.0793 grams, within the error range, the medicine finally entered the reaction tube.

The two reaction tubes have been pasted with serial numbers, which are the initials of Ai Guichu's name-the page number of the experiment record-the reaction serial number. Ai Guichu explained it to Ai Gong in detail, and then let Ai Gong do it.Because Ai Gong mainly went through some pillars in the laboratory before, tapped a little board, and really never had a reaction.

Ai Gong cautiously and a little excitedly added the medicines by serial number.When Ai Gong finished weighing all the solid medicines and adding them to the reaction tube, Ai Guichu had already prepared the liquid reagents and took out the micro syringe.

"What we need to do now is to vacuumize and then fill with nitrogen, probably three times and three times." Ai Guichu said, connecting the branch ports of the two reaction tubes to the rubber tubes, and then turned on the vacuum pump, saying, "Remember to replace the branch tubes with rubber tubes. The piston opens, and the opening speed is slow when pumping air."

As he spoke, Ai Guichu slowly unscrewed the piston, and he could hear the sound of the vacuum pump making a "crack clack".

"This is to prove that there is gas in the tube body. After the sound disappears, you can unscrew the second three-hole piston." Ai Guichu turned the piston and heard the sound of the vacuum pump again.

"Nitrogen can be filled in about one or two minutes." Ai Guichu stretched out his arms to embrace Ai Gong who was standing a little far away, wrapped his arms around his waist, and said: "When switching to nitrogen, the piston should rotate faster, so that it can enter the air in an instant." The nitrogen gas can blow the solid powder on the tube to the bottom of the tube."

Ai Gong struggled lightly, but did not dodge, then stretched out his hand to push Ai Guichu away, and said, "Brother Guichu, it was agreed at the time not to move or move, right?"

Ai Guichu let go of Ai Gong regretfully, looked down at Ai Gong's hairy hair, then stretched out her hand to turn the piston, and instantly heard a sound of inflation.

"When you turn the piston slowly, you can't hear such a sound." Ai Gui said, and after a while, opened the other piston.

What followed was the monotonous three pumps and three recharges. Ai Gong only kept his hands on the side of the fume hood, watching Ai Guichu's movements.In the end, Ai Guichu closed the piston at the outlet of the branch pipe, then closed the three-hole piston, took off the reaction tube, and said: "Prepare the label paper, and then add the liquid reactant."

Adding liquid reactants is to use a micro-syringe to inject the reaction tube from the rubber stopper. The micro-syringe is vertically facing down, and the liquid is dripped to the bottom of the tube, and then the needle is pulled out according to the place where the needle was inserted, and the needle hole is pasted with label paper. It's like a nurse removing a needle from a patient.

Then the catalyst is added, and finally the solvent is added, using an extended needle (mentioned in the previous article), turning the needle to flush the tube body once.

Next is to seal the nozzle with parafilm.

The front was fine, but at the last step, Ai Gong's expression changed when he saw Ai Guichu take the parafilm. Fortunately, it was not obvious that he was wearing a mask, but he obviously felt his face became hot.

And this Ai Guichu didn't seem to see it, deliberately handed the parafilm to Ai Gong, and taught Ai Gong to wrap the parafilm hand in hand.

Because it was Ai Guichu who surrounded Ai Gong from behind, holding his hand around the mouth of the tube, as if holding Ai Gong in his arms, Ai Gong was wrapped by Ai Guichu with one hand and held the tube, Ai Guichu squeezed and stretched the parafilm...

After sealing the two reaction tubes, Ai Gong can already cook eggs on her face!It's not that being held in Ai Guichu's arms is shy, but the action of sealing and winding the mouth of the nozzle is really... the past is unbearable...

For the first time, Ai Guichu did not continue to tease Ai Gong, but just asked him to put the reaction tube at room temperature and stir it on a magnetic stirrer for about [-] minutes.

After waiting for 10 minutes, Ai Guichu asked Ai Gong to clean up the fume hood and turn off the equipment in the fume hood. The two of them had nothing to do and stared at each other.

Under normal circumstances, at this time, it is usually processing the previous product or washing the instrument.But Ai Guichu just came back, and there is no product to deal with, except for these micro-syringes and no equipment to wash. Each of these micro-syringes only needs to repeatedly pump ethyl acetate for more than six times, and dry it with a hair dryer.

It took less than 10 minutes to deal with these things. Ai Gong didn't take the initiative to speak out because of embarrassment, and Ai Guichu looked at Ai Gong with a smirk because of her bad taste. The atmosphere in the laboratory was very weird, except for the noise of the fume hood. There is no sound.

Therefore, the ringtone of the mobile phone is particularly abrupt.

"Xiao Gong, Xiao Gonggong~Xiao Gonggong answered the phone~" Pseudo-Niang Sun's coquettish voice sounded, Ai Guichu's face changed slightly, but seeing Ai Gong didn't even look at him, he took out his mobile phone and walked out of the laboratory.

Ai Guichu looked at Ai Gong's back, but didn't follow her.

"You said...really?" Ai Gong blinked, listening to the other party's speech, her body gradually froze, and her voice couldn't help but stop.

"...Got it." Ai Gong said dryly, took down the phone, and hung up.Look back at the lab.

from this angle.Ai Guichu was just blocked by the fume hood, and Ai Gong looked at Ai Guichu's direction with a gloomy expression, and it took him a while to adjust his mood and walk back.

The author has something to say:

I didn't go to the lab tonight... I have a premonition that it will be embarrassing to see my brother tomorrow...

He expressed his feeling that senior brother is really...too difficult...
