Qi Min waited at the entrance of the biology department for about ten minutes, and saw a young man wearing a baseball jersey and carrying a schoolbag hurriedly running here.

In Qi Min's title system, you can call "girl" and "young man" in your teens and thirties, but this boy looks significantly younger than a doctoral student. And ordinary undergraduate students don't often haunt the laboratory gathering area here, so Qi Min can easily know that he should be the freshman who came to borrow a bicycle.

Qi Min walked out of the building door and took the key out of his pocket: "You're here to borrow a bicycle, right?" ”

"Yes!" The young man hurriedly ran over and carefully took the key, "Thank you......"

Qi Min took him to the front of his N-hand 28 bar in the carport: "The car is a little broken, but it can still be ridden...... Presumably. Be careful, the right hand brake is loose, it's better to use the left gate. ”

"Okay, no problem." The young man smiled at her, looking a little silly, "Thank you, sister!" ”

Sister...... As a serious PI, Qi Min has changed from the "senior sister" of doctoral students to the "sister" of undergraduates. Forget it, she knew that she was wearing this lab coat with a lot of traces of reagents, and she didn't look very majestic, so she was a young man who praised her for being young and beautiful in disguise.

"It's fine." Qi Min said, "Ride slowly." ”

Watching this first-year undergraduate young man ride away on her N-hand 28 bars, Qi Min looked down at the pink DMEM medium on her body and the white coat that had dried up with rat bloodstains, thinking that she might have to buy a new batch of lab coats.

——

Qi Min went back and re-attached the code that generated 256×256×256 miniature brain-like bodies. Now the full-size brain-like body has been run, but if the miniature brain-like animal experiment has a BUG, then for the sake of insurance, it is better not to use the full-size brain-like body to act rashly, lest something go wrong, and it would be a waste of time for such a big thing to run again.

Ke Li was also frustrated by the results of such animal experiments, and he checked the indexes of 256×256×256 virtual neurons of the miniature brain-like body on his computer, but he did not see anything wrong. And even if you use it for machine learning, you can get the results you want.

Qi Min and Ke Li discussed for an afternoon, and finally decided to write an email to the miniature callosum interface research group at the Paris École Supérieure and ask them about the animal experiments at that time.

After sending the email, Qi Min began to check her brain-like code.

She read line by line on Jupyter, and she couldn't read any problems. It's just that suddenly the WeChat on the PC side pops up and shows that someone wants to add her friends.

Qi Min clicked on it and took a look, and the remarks said "Liu Kun - return the bicycle".

It was the young man who borrowed the bicycle, and Qi Min passed. Anyway, it is probably useless for her to check the code now, so she will go downstairs to get the key without delaying time at all.

On WeChat, this first-year undergraduate student named Liu Kun sent a message: "Sister, the confident car has run out, is it convenient to get the key now?" ”

"Yes, I'll go down right away." Qi Min replied.

Then she got up from her seat and passed by the waste tank outside the laboratory and found that the waste tank was almost full, so she went back to put on her lab coat, put on two layers of latex gloves, and carried the waste tank down by the way.

Qi Min's research group only does dry experiments in one acre and three points of land in his laboratory, and cell and animal experiments have to go through the public experimental area, so there is very little garbage produced in his room, and no special person is hired to clean it. The cleaner aunt in the laboratory next door is very nice, and she usually takes out the garbage from Qi Min's laboratory when she takes out the garbage, and sometimes she also dumps the waste liquid by the way. But it happened that during this time, they were doing animal experiments, and the waste liquid produced was too much, and the aunt in the laboratory next door couldn't pour it, so they had to rely on themselves.

Qi Min carried the waste liquid bucket downstairs, a little surprised that this thing was quite heavy. One liter of water is one kilogram, and this waste liquid bucket must have at least more than 30 liters, and it is this kind of difficult shape, and it is really a bit difficult for her to carry.

If it's an ordinary PI, then go and call the male student to pour the waste liquid. But Qi Min doesn't like to engage in those hierarchical concepts, and she has to pour the waste liquid by herself with a twitch in her head, so how faceless does it seem to go to Chen Linyou or Ke Li now?

She just dragged the waste liquid bucket out and dragged it until she reached the door, just in time to see Liu Kun who came to return the bicycle outside the door.

The young man saw her dragging the waste bucket and ran over to help. Qi Min hurriedly stopped him and said, "Don't touch this, you don't have gloves!" ”

"Oh......" Liu Kun retracted his hand stupidly, and asked with some hesitation, "Is this poisonous?" I look pretty heavy, why don't you let me come......"

Qi Min thought that he had borrowed his own bicycle, and it made sense to go back to help her. Although her bicycle is very broken, the waste liquid from this cell experiment is not poisonous.

Therefore, Qi Min put down the waste liquid bucket and took out four latex gloves from the pocket of his lab coat: "Then you have to wear gloves." ”

Liu Kun put on his gloves and reluctantly picked up the waste liquid bucket. But he still carried the waste bucket to the unified waste collection place step by step.

After the young man finished pouring the waste liquid, Qi Min sincerely thanked: "Oh, thank you so much." ”

"It's okay," Liu Kun was a little panting, but still said, "It's not too heavy, I can help if I can." ”

Qi Min felt a little guilty, and she asked undergraduates to carry the waste liquid bucket that she couldn't carry, as if she was a little suspected of abusing her power.

In order to avoid leaving a bad impression on the young man about the school teacher, Qi Min proposed: "Why don't I invite you to dinner?" ”

"No, no, no!" Liu Kun hurriedly waved his hand.

"Then I'll give you a cup of coffee." A cup of coffee from the automatic coffee machine downstairs in the biology department hall costs five or six yuan, and the price is still more appropriate, "You take off your gloves and wash your hands well." ”

Liu Kun glanced at the gloves, probably because the waste liquid bucket had been dirty, and his latex gloves had also left ash marks one by one. Although latex gloves can basically isolate all harmful reagents used in biological experiments, they are not comfortable to look at like this.

Liu Kun and Qi Min returned to the biology department building. While he was washing his hands, Qi Min went to get a cup of mocha coffee.

The young man came out after washing his hands and saw that the coffee had been beaten, so he had to take it and drink it. While he was drinking coffee, Qi Min asked a little about their "combination of study and work" club.

Liu Kun just said: "I also joined the club in the first semester, and the specific situation is not clear. Our club is to study the theory of socialism and so on...... Sister, if you are interested, you can also join the group. ”

Qi Min thought about it, forget it, it makes sense that Anton belongs to the student club of outsiders. She is a teacher officially employed by the school, and diving in the student club group can really cause misunderstandings.
