The electric switch was in the corner of the laboratory, the size of A4 paper, Pu Weizhi lifted the lid, put his hand in, looked carefully, and turned around and said, "It's all normal." It's not a problem here, see if this water bath is broken. ”

Ji Yanqi unplugged the socket and plugged it in, pressed the start switch, the display screen lit up for a moment, the light went out immediately, and then there was a slight "click", obviously the circuit was broken.

The laboratory is very large, usually with four or six benches next to each other, and the two benches share two faucets, sinks, and two sockets.

When the two classes of the major take an experimental class together, the laboratory will be occupied, and now the next class will have an experimental class alone, with more than 20 people, and a few tables and a few sets of equipment left. Zhou Li's experimental bench moved the equipment over and replaced it with a water bath.

"Try this." He bent down to plug in the socket, Ji Yanqi removed the original water bath, and took out all the other glass instruments.

Zhou Li pressed the switch, and the new water bath didn't even light up, and the two of them were a little confused.

Zhou Li fell on the edge of the pot with one hand, he had always loved experiments, and he was so frustrated by this, so much slower than other classmates, he was irritable in his heart, "What the hell is going on." ”

Ji Yanqi didn't know what was going on.

I don't know how to deal with this. Seeing that his companion had a temper, although he was also anxious in his heart, he was afraid that the experiment would have to be done in the afternoon and he would not be able to eat at noon, but he didn't dare to say a word, for fear of aggravating Zhou Li's depressed mood.

Asked in a low voice, "Could it be that this pot will not work?" Taking a look at Zhou Li first, his expression was unmoved, obviously not thinking that the two pots would have problems at the same time.

In fact, she also thinks that this probability is very small. Fu looked at Pu Weizhi again, his gaze was not on the two of them, he should be thinking about what she said, and his gaze fell on the other water bath that no one was using.

After a pause, he said, "The equipment in the laboratory is old, and most of it has been tried when it was prepared for you, and it can be used." He paused, but still considered her proposal, "Go and move here." ”

Ji Yanqi took a few steps over.

Another one was moved, Pu Weizhi took it from her hand, and put it in the vacant position where Zhou Li had just removed the second water bath, "Zhou Li, go over and see if there is anything abnormal in the electric switch." ”

Zhou Li was stunned.

Pu Weizhi plugged the socket in, "Forget it." I'll go over. ”

Pu Weizhi walked towards the corner, Ji Yanqi stood behind Zhou Li, and felt that he didn't need himself here, so he followed Pu Weizhi and walked that way.

"What are you doing here?"

Ji Yanqi replied truthfully: "I can't understand this, I want to learn it." ”

Pu Weizhi's eyes showed a puzzled look, but it was fleeting, and soon changed to a light smile, he lifted the lid and pointed to the switch inside, "There are signs, you can understand them if you look carefully, you don't need to deliberately learn them." ”

"Okay."

"You're pretty studious."

"It's okay, don't be verbose, let's see if there's a problem, I don't want to go without food at noon."

There was a trip. Pu Weizhi frowned, it was okay just now, but it was a problem here, he restored the switch, "It may be that there are more devices used at the same time, I opened it here, and asked Zhou Li to try it." ”

Ji Yanqi nodded, and passed the words to Zhou Li, Zhou Li pressed the switch of the water bath, and in just a few seconds, he stood up and shook his head vigorously here, with a depressed face, "It's still not good, it's jumping." ”

Ji Yanqi looked back at the third button of the switch, "How can this be." What should I do? ”

Before Pu Weizhi finished speaking, something happened on the other end again. The classmates who were doing experiments at the table opposite her and Zhou Li and the classmates on the experimental table next door shouted "Senior brother, what's going on".

Pu Weizhi ran over quickly, "What's going on?" ”

Zhu Xin had just come back with the medicine, and the beaker was still in his hand, "The power suddenly went out, I don't know what's going on." ”

"Can you just use it?"

Yin Huan picked up the thermometer and pulled it to the side where the scale could be seen to show everyone, "Yes, seventy-eight degrees, the prediction will be over in another hour and a half." ”

Zhu Xinyi: "Didn't you cut us off?" ”

Ji Yanqi looked at Pu Weizhi, "You didn't press it wrong just now, right?" ”

"Nope."

He thought for a moment, "I probably know, sister, you go to the electric switch and watch, and we'll try to change the socket later." ”

After trying for so long, Ji Yanqi was a little desperate. Nodding dumbly, he did as he said, walked to the corner to guard the electric switch, and saw Pu Weizhi turn around to her and Zhou Li's experimental table from a distance, move the earliest water bath to another experimental table, and plug it into the socket.

He turned on the switch, and Ji Yanqi made a "click" above his head, scaring a spirit. Looking up, the fourth switch jumped. Pu Weizhi looked over, she shook her head, so he carried the water bath to the next test table.

I tried two or three tables one by one.

Zhou Li originally followed him from one experimental table to another, and finally didn't bother to move, watching Pu Weizhi busy. Zhu Xinyi and Yin Huan supported their heads with their hands, Ji Yanqi made an "OK" gesture, and the two of them synchronized with Pu Weizhi's movements, and then showed disappointed expressions at the same time.

It's as if a power outage is contagious.

The two of them were bored and took out their phones to play mini-games.

"Is that okay?"

"Wait, there's something wrong with this socket," Pu Weizhi bent down, used a little force, pressed the socket tightly, pressed the switch, straightened up, waited silently, and said profusely, "There are two left, if it doesn't work, I can't help it." ”

"It's really not good, I'll come to class with the next class in the afternoon, it just so happens that I haven't seen you for a long time, take a second look, and when I graduate, you won't have a chance." He sighed, no matter how he heard it, there was a bit of schadenfreude in it, adding fuel to the fire, making Zhou Li roll his eyes with hatred.

"It's not a parting between life and death."

"I'm afraid that I will forget each other at the end of the world," he said, and his tone was suddenly surprised, "Yo roar, this seems to be okay, this one didn't jump." ”

Zhou Li jumped down from the experimental table all of a sudden, bent down to look at the display disk, the red numbers were dazzling, his eyebrows fluttered for a while, and a fist smashed on Pu Wei's back, "It's okay, Brother Pu, it's all right." ”

"Zhu Zhu, is it okay over there?"

"Yes, you can."

Ji Yanqi breathed a sigh of relief, moved all the medicines to this table, cleaned up the original table, and found that the other students had experimented more than halfway, "Can we stay here at noon?" If the experiment is not done. ”

"Yes."

"Is it okay for me and Zhou Li?"

"I'm watching here, and if something happens to you, I'll be responsible."

Ji Yanqi nodded, inserted the glass rod into the mouth of the three-mouth flask, stirred twice, and suddenly lowered his voice and asked, "Do you get paid for this?" ”

Pu Weizhi leaned over and put the experimental equipment they didn't need into a drawer, "The teaching assistant has a little salary, but it's not much, it's okay to have a meal, okay at night?" ”

"Aren't you busy?"

"Is there still time for a meal?" He softened his tone, "You don't want to go to dinner with me?" In my heart—"

"Eat, eat, eat." She hurried to stop.

Pu Weizhi packed up his things, explained a few words, was called away by other classmates, and was just pulled to Ke Ji's experimental table, Zhu Xinyi took a few steps over, and pulled Ke Ji's separating funnel to his territory.

Zhou Li sped up the experiment, Ji Yanqi was lazily recording data on the side, seeing that Zhou Li was busy, he wanted him to be careful and not to drop any instruments, and he didn't know how to speak for a while, so he wanted to shut up.

At nearly twelve o'clock, the other groups successively reached the cooling stage, watching everyone start to discuss the cooling speed, Ji Yanqi was heartbroken, sent a message to Zhu Xinyi, and asked her what she ate at noon.

Zhu Xinyi's experiment was nearing the end, she took off her gloves and threw them into the trash can, and raised her eyebrows and said to Ke Ji: "See this bucket?" Your destination. ”

Not to be outdone, Ke Ji touched the waste liquid bucket next to the trash can with his toes, "See this bucket?" Your destination. With that, he took a disposable glove from the shelf on the side, put them on, and pretended to unscrew the lid of the waste tank, and a pungent sour smell came out of it.

"Smell it? Your—"

Ji Yanqi couldn't stand it, and poked him, "Mr. Ke, don't you make trouble, don't you panic?" ”

"What's so panicky about him, he just likes the smell."

Ji Yanqi felt that it was better not to know each other. From the class committee to teammates, no matter what they do, there is no harmony at all, and even if the two occasionally agree on the same page, they will unanimously hate each other because the other party agrees with themselves.

"You two go on, I'll order takeout."

Only then did Zhu Xinyi remember that there was something to do, "Eat Xiyuan, I'll pack it for you." ”

"I prefer Dongyuan, if you want, I want to eat chicken pot, or plum cabbage and pork, and it would be better if there was a cup of milk tea."

After listening, Zhu Xinyi looked serious, "Listen to what you are talking about?" Why don't you order takeout? I ate West Garden with Yin Yin. ”

"I don't love it anymore."

Her voice fell, and a shadow turned behind her, Pu Weizhi had just finished telling Ye Zhisheng why their temperature couldn't rise, and his footsteps hurriedly walked to the other side.

Her gaze followed.

"Senior brother, the ice machine is broken."

The person who spoke was Zhou Li.

It's much faster to cool down with ice, and I don't know when I'm going to run out of ice. Ji Yanqi suddenly put his arm on Zhu Xinyi's shoulder, buried his head in the past, and looked pained, "I can't eat, there is no ice." ”

Ke Ji and Zhu Xinyi were silent for two seconds and laughed at the same time.

"I'm sorry, sister, I really can't help it."

"You two are too unlucky today, it's really not good, let's come back tomorrow to do the experiment."

Ji Yanqi: "......" was almost calm, she followed over to watch Pu Weizhi and Zhou Li check the ice machine, "Can you do it?" ”

Pu Weizhi worked seriously, and he didn't even look back, his tone was calm, but he smiled slightly, and he looked like he was not concerned with the work at hand, "Have you asked this question?" So familiar. ”

Yes.

At the time of military training.

"What the hell are you going to do?"

"Nope." He straightened up, "I'll go upstairs to the lab to rub a little, you guys adjust the temperature of the water bath first, and also, stir faster, add less ingredients." ”
