"You just sent him away?" Liang Jing asked while wearing goggles and holding a test tube clamp with one hand. She leaned her body to keep herself as far away as possible from the ventilated kitchen where the experiment was being conducted. On the black test bench on the other side, a small round-bottomed flask is heated on an asbestos net, and the steam from the boiling liquid in the flask is cooled by a condenser tube, and a drop flows into the Erlenmeyer flask. Chen Ying sat on a square bench near the heater, watching Liang Jing walk around, occasionally observing the thermometer hanging from the mouth of the flask for her.

"How else?" Chen Ying stared at the thermometer and said.

"Saw him off at the train station last night?"

"Hmm."

"Is there a lot of people at the train station?"

"No, at this time, most of the people have gone back. He booked a night car, so there were very few people. ”

"You waited until the train left before leaving?"

"Pretty much."

"He's been watching you from the window?"

"Hmm."

"It's romantic. How can you be willing to let him go back? Obviously, he had already decided not to leave. ”

"I don't want to be a barrier between him and his family. Besides, he should go home, even if he doesn't think about the New Year, his younger brother shouldn't miss his sister's wedding. ”

"Aren't you sad that he's gone?"

"It's false to say not to be sad." Chen Ying watched the water in the condenser tube flow hurriedly, "But I don't want to be too selfish, I don't want to use love to kidnap each other's lives." Many people like to stick together all day long because they are afraid that separation will sourage their relationship with each other. But even so, there are still many people who break up and become strangers. So I think true love is not to tie each other to your side all the time, but to always have each other in your heart, no matter how far apart you are. ”

"Your argument reminds me of a passage I read before: 'If you desire something, you have to set it free, and if it comes back to you, it is yours; Otherwise you would never have had it. ’”

"Sure enough, the Great Writer's version is much better than mine."

"You still compare yourself to Alexandre Dumas, huh?"

"Don't dare to be."

They laughed together. Less than a third of the liquid in the round-bottom flask remained, and Liang Jing poured the liquid in the small test tube in his hand into an brown glass bottle and put it on the cap, and extinguished the alcohol lamp. Chen Ying closed the water valve of the condenser pipe.

"How was the opening ceremony this morning?" Liang Jing took off her rubber gloves and asked while washing her hands.

"It's not bad, there are a lot of international students who participated, and everyone took a group photo wearing the national flag of the country they represented. Then the President of the General Assembly announced the minutes and the schedule, and the first day of activities was over. ”

"It's still early." Liang Jing put the washed instruments on the shelves in turn, shook the water in his hand and said, "There is still one surface tension experiment left that I can't do now, because it needs to be very quiet - but this experimental building is next to the subway, and just as I want to record the data, the subway passes, and the water droplets fall down at the slightest vibration, so there is no way to measure, so I can only wait until the subway stops in the middle of the night." ”

"Go back and rest for a while?" Chen Ying asked with concern.

"I can't sleep when I go back now. Ye Feng is waiting at the door, let's go down quickly. ”

"What are you going for?"

"Go somewhere interesting."

"Where?"

"It's a bit far. But if you leave now, I guess I'll be back for dinner before seven o'clock. ”

"What the hell are you going to do?"

"I can't tell you just yet, it's fun to keep it a little mysterious—you'll know when you get there. Alright, let's hurry downstairs. ”
