how to fall in love

Chapter 16

Xiao Jie: Starting from this week, our department will conduct a full-day metalworking internship on Saturdays. Everyone gathers at the south gate of the factory next to the northwest playground at [-]:[-] am every Saturday.Please reply

Looking at the message sent by Xiao Jie in the group, Sun Guiyi first replied with "received", and then clicked on the chat box with Qi Chuqi: We have sent a notice, and we will arrive at the south gate of the factory at [-] o'clock on Saturday

Qi Chuqi was probably holding his mobile phone. As soon as Sun Guiyi's message was sent, Qi Chuqi's message came back immediately: the same

Qi Chuqi: At that time, we will contact you on WeChat, and I will find you during the break

Sun Guiyi: Is it convenient?

Qi Chuqi: Your reply is a bit fake

Sun Guiyi looked at the news and smiled: "Okay, then we will contact you by letter."

Qi Chuqi: OK

Qi Chuqi: Are you in the dormitory this afternoon?I'll find you, let's go to the lab together

Sun Guiyi thought for a while: It's ten past twelve after class, I want to go straight to the lab after dinner, or I'll wait for you at the door of the lab

Qi Chuqi: Which cafeteria are you going to, I will wait for you in the cafeteria, we will eat together, and then go to the laboratory together

Sun Guiyi: Four Canteens

Qi Chuqi: Alright, then I will wait for you at the main entrance of the Fourth Canteen

After Sun Guiyi finished chatting with Qi Chuqi, he locked the screen and planned to put the phone away.

Xu Chao sat next to Sun Guiyi, watching him chatting with others.

After Sun Guiyi finished chatting, he asked, "Who are you chatting with?"

"Huh?" Sun Guiyi turned to look at Xu Chao, "Chu Qi, tell him about going to the laboratory in the afternoon."

When Xu Chao heard this, he didn't care much and said, "Oh, yes, you guys are going to do the experiment this afternoon... Have you finished writing the experiment report that will be received tomorrow morning?"

Sun Guiyi nodded, "It's finished."

"Let me take a look. I haven't had time to write about the sports meeting these two days."

"Wait for me to find..."

Sun Guiyi dug out the experiment report from his schoolbag, and handed it to Xu Chao.

Xu Chao took the experiment report and asked casually, "By the way, when are you going to the laboratory in the afternoon?"

"Just go after dinner."

"Then you and Lao Qi will meet in the laboratory."

"No."

"Ok?"

"He was waiting for me in the cafeteria, and we went to the laboratory together after dinner."

After hearing Sun Guiyi's words, Xu Chao slowly turned his head to look over.

Sun Guiyi looked bewildered, "What's wrong?"

"No, I just think that you two have such a good relationship, and even went to a laboratory and asked to have dinner together."

"Don't you have a good relationship? Haven't you all played together before?"

"That's right." After finishing speaking, Xu Chao turned his head and muttered in a low voice, "But we didn't deliberately make an appointment to go to the cafeteria to have a meal together before playing."

……

"Okay...you turn on the vacuum pump."

Qi Chuqi came to the laboratory after eating with Sun Guiyi.They arrived earlier, and the brothers and sisters in the laboratory hadn't come back at that time, Sun Guiyi and Qi Chuqi directly took things from Zhao Lu's laboratory bench, and went to the fume hood to react.

After the experimental device is set up, they need to turn on the vacuum pump to evacuate the internal space of the experimental device.

Hearing Qi Chuqi's words, Sun Guiyi turned on the switch of the vacuum pump, "Why does it feel like this pump is not very easy to use?"

"The sound is not too loud, maybe it's old."

"It always feels like I can't smoke clean."

"How about we change the oil pump?"

"Didn't senior sister say that the oil pump is too powerful, and it's easy to pump everything out?"

"Senior sister said that it is easy to drain the solvent by direct pumping. There are double pipes in the middle, so it should be fine."

Sun Guiyi recalled for a while, "It seems to be so. Should we change it?"

"Look at you, if you think this water pump is not working well, then we will change the oil pump."

"You guys are here so early."

While Sun Guiyi was talking to Qi Chuqi, Zhao Yu returned to the laboratory after finishing his meal.

As soon as she entered the laboratory, she saw Sun Guiyi and Qi Chuqi gathered in front of the fume hood, so she walked over.

When Sun Guiyi and Qi Chuqi saw Zhao Lu, they greeted her together, "Sister."

"Have you encountered any problems?"

Qi Chuqi and Sun Guiyi looked at each other after hearing the words, and Qi Chuqi said, "We feel that the water pump is not working well, and we want to change the oil pump, but we are not sure whether the oil pump will pump out the solvent, so we are a little hesitant."

"The solvent is pumped away by the oil pump because of the vacuum inside, and the boiling point of the solvent is lowered. During the reaction, the solvent is vaporized before being pumped away. The reaction temperature of our reaction is quite low, and if we use double-row tubes, we don't have to keep It’s evacuated, so it won’t vaporize. You can use an oil pump if you want. But your side has been evacuated, and the connection of your pipe is tightly pressed because of the vacuum inside, and you can’t pull it out. You have to close this valve first, and then ventilate from this side...you should be able to understand this."

Qi Chuqi and Sun Guiyi nodded together.

"Okay. Then you can change it." After finishing speaking, Zhao Yu left directly.

Qi Chuqi and Sun Guiyi watched Zhao Yu enter the lounge, and then began to change the pump.

After they evacuated the vacuum, the reaction was considered to be completely done, and then they waited for the reaction of the experiment to be completed, and then proceeded to the subsequent processing.

"Then let's watch here."

Listening to Sun Guiyi's words, Qi Chuqi nodded, "Didn't Senior Sister say that she should watch and not leave her?"

Sun Guiyi looked around, "Is there still a mixer? If there is no mixer, after the reaction is over, we will have no place for dialysis."

"You go and see."

After Qi Chuqi finished speaking, Sun Guiyi walked around the entire laboratory, and then came back, "There is still a space for the innermost stirrer."

"it is good."

The reaction time of the experiment they are currently conducting is not too long. Sun Guiyi and Qi Chuqi chatted and waited while Sun Guiyi climbed on the laboratory table next to the fume hood to write homework for a while. arrive.

Sun Guiyi glanced at the reaction device, and said to Qi Chuqi, "I'll get the breathable bag and clips, and you will dismantle the reaction."

"Is the dialysis bag soaked?"

"I just soaked it in water and put it on the mixing table."

Qi Chuqi nodded, "Okay."

Sun Guiyi went to the other side, and came back after a while, holding a [-]-liter beaker full of water in his hand, with several sections of plastic film still soaking in it.

"Really, before I entered the laboratory, I never thought that dialysis was such a low-level operation."

Qi Chuqi chuckled when he heard the words, "It's not because the dialysis bag is more powerful."

"It must be our specialty who invented the dialysis bag."

"why?"

"Because it belongs to the material."

Qi Chuqi nodded, "It's possible."

While talking, the two put all the reaction products into dialysis bags, and then put the beaker on the stirring table.

"Okay, let's go back. I have no class for the first and second periods tomorrow, and I will change the water then."

Sun Guiyi nodded upon hearing the words, "Then I will change tomorrow afternoon."

"Okay. Let's go back after washing the instruments."

Then, Sun Guiyi and Qi Chuqi packed up their things and left the laboratory together.

……

Time passed little by little.

Early on Saturday morning, Qi Chuqi came to the factory early.

After standing still at the door, he looked up and looked around.

At this moment, there are already classmates who arrived early at the gate of the factory.

Qi Chuqi took out his phone and clicked on the chat interface between him and Sun Guiyi: I'm already here, where have you been?

Sun Guiyi did not reply to Qi Chuqi immediately, and Qi Chuqi was not too anxious.After he exited the chat interface, he clicked on a small game to start playing.

As soon as he finished playing the level, someone suddenly patted him on the shoulder.

Qi Chuqi raised his head and saw Sun Guiyi standing in front of him.

Qi Chuqi looked at Sun Guiyi, put away his phone, and smiled, "You're here."

Sun Guiyi nodded, "Yeah. Why are you alone? Where's Xinghan?"

"Xinghan came back yesterday afternoon and felt a little uncomfortable. He asked for leave today, and he will make up with other colleges later. Why are you alone?"

Sun Guiyi said frankly, "Xu Chao was too slow, so I didn't wait for him. Where will your class gather later?"

"I just said it's on the south gate side. Maybe wait for more people to come and organize it together. I haven't seen our class yet..."

As soon as Qi Chuqi said this, he saw Guo Hao walking across from him.

Seeing Sun Guiyi and Qi Chuqi looking at him together, Guo Hao smiled, "Oh, Guiyi is such a coincidence."

Sun Guiyi smiled, "What a coincidence, isn't it normal for us to have the same metalworking internship time in the same college?"

Guo Hao nodded when he heard the words, "Yes. Then you want to come to our class to play later?"

Sun Guiyi shook his head, "I don't. Chuqi will come and play with me later."

Guo Hao looked at Sun Guiyi, then turned his head to look at Qi Chuqi, and suddenly realized, "Oh..."

Qi Chuqi looked at Guo Hao's expression and was speechless, "Oh what. Why did you come here at this time?"

"When I set the alarm clock yesterday, I set the wrong time. I was afraid that I would forget about it, so I just came here. Why are you two so early?"

"Ah?" Sun Guiyi was stunned for a moment, "It's nothing, I just made an appointment at this time, so I came over."

"Huh? Did the two of you have an appointment?"

Qi Chuqi nodded, "Why, what's the problem?"

Guo Hao quickly shook his head, "There must be none..."

It was still early, and the three of them started chatting here at the door.

As time passed, more and more people came around them.

Later, Xu Chao and Chen Yu also came over to chat with Qi Chuqi and the others.

Chatting and chatting, the teacher in charge came over, and each class assembled separately.

In this metalworking internship, each class was separated according to the project, and Sun Guiyi and his class were brought to a workshop.

The teacher first introduced the machine they were going to use, and then demonstrated how to use the machine, and then asked all the students to form a group of four to complete a device with the machine demonstrated today.

Sun Guiyi, Xu Chao, Chen Yu, and Xiao Jie happened to stand together because of their height, so the four of them formed a group.

When the teacher finished assigning tasks for everyone to start, Sun Guiyi looked at the remaining three people and said, "Which one of us will come first?"

Looking at the earnest eyes of the three people, Sun Guiyi sighed helplessly, "Let me go first."

So, Sun Guiyi went forward to get the materials needed for the operation, then walked to an idle machine and started to operate.
