Li Peicheng was about to ask Liu Zhiyun what happened, but Liu Zhiyun had already turned around and returned to the office sadly.
Seeing this, Li Peicheng had no choice but to put down what he was doing and follow him into the office.
"Who messed with you Zhiyun?" Li Peicheng asked.
"It's you, you annoying guy!" Liu Zhiyun raised her mouth in anger.
"I, what's wrong with me?" Li Peicheng asked innocently.
"Let me ask you, where were you last night? Why didn't you have dinner with me? Why didn't you go to study late? Why didn't you call me?" Liu Zhiyun looked at Li Peicheng and asked questions again and again.
Li Peicheng couldn't laugh or cry when he heard this. When did he need to report these things to Liu Zhiyun. But Li Peicheng could see that Liu Zhiyun's attitude was very serious, and it was not like being unreasonable or joking.
"I was in a hurry last night, so I didn't take care of you!" Li Peicheng replied. He didn't want to tell Liu Zhiyun about Lan Xiaoxue and the others, but he had an intuition that it was better not to tell her about it.
"How about we have dinner together and study by ourselves in the evening?" Li Peicheng continued.
"Who cares?" Liu Zhiyun's anger had subsided a bit, and she finally realized that she seemed to be being unreasonable, and replied with a slight blush on her pretty face.
Li Peicheng saw a slight blush on Liu Zhiyun's cheeks, feeling particularly beautiful, and couldn't help but be stunned.
"If you haven't done the experiment yet, why are you standing here looking at it?" Liu Zhiyun felt very happy when she saw Li Peicheng staring at her. Her disappointed mood had long since disappeared. She rolled her eyes at Li Peicheng and said in a very feminine voice.
"Then you're not angry anymore?" Li Peicheng asked.
"Who is so boring and angry with you?" Liu Zhiyun couldn't help but feel angry and shy when she saw Li Peicheng mentioning what happened just now.
When Li Peicheng saw this, he chuckled and turned around and left the office.
After Li Peicheng walked out of the office, Liu Zhiyun held her chin in her hands and stared out the window in a daze, feeling her heart beating very fast.
Have I fallen in love with him? Is this love? Liu Zhiyun asked herself.
But the shadow of her family was like a nightmare that could not be shaken off, shrouding her mind. Soon Liu Zhiyun's eyes showed sadness and melancholy, because she thought that even Li Peicheng had fallen in love with her, and this love
There will be no gain.
"Now that you have thought about resisting to the end, what are you still afraid of? Even if you fail to resist in the end, you should be happy during this period." Li Peicheng's words flashed through Liu Zhiyun's mind.
Liu Zhiyun quickly put away the sadness in her heart. She wanted to live happily with Li Peicheng for a while.
Liu Zhiyun left the office and returned to the laboratory. When she saw the back of Li Peicheng busy in the laboratory, she couldn't help but smile.
Many people in the laboratory saw the smile on Liu Zhiyun's face. This may be the first time they saw Liu Zhiyun's smile. The boys were stunned, their eyes were so fixed that they couldn't move at all. The girls looked at it and were envious.
I'm so jealous, why don't I have such a touching smile?
"Pei Cheng, please stop the experiments here for the afternoon!" Liu Zhiyun walked to Li Peicheng and said.
"Why?" Li Peicheng asked.
"I want to test the heavy metal content of a batch of samples digested yesterday. Don't you want to learn how to operate the instrument?" Liu Zhiyun said softly.
"Oh, you have to use the instrument today!" Li Peicheng said with some surprise.
"Yeah!" Liu Zhiyun nodded.
There are courses on instrument analysis in university courses, and Li Peicheng has also worked hard on it, and has done some research on the principles. But there is basically no actual operation. The teacher just took them to visit the instruments and introduced them.
The structure of the instrument.
The Department of Resource Science originally had a Nissan Shimadzu Atomic Absorber, but due to poor management at the beginning, the number of people using it was relatively mixed, and the instrument failure rate was relatively high. Later, it was changed to a dedicated person to manage it. It is rare for a scientific research support staff like Li Peicheng to operate it personally.
Opportunity.
"First put the lead hollow cathode lamp on and let it warm up and stabilize for a period of time." Liu Zhiyun directed Li Peicheng to operate step by step.
"The lead hollow cathode lamp is used to emit characteristic spectral lines. The characteristic spectral lines it emits excite the ground state lead atoms in the ignited gaseous solution. The lead atoms absorb the characteristic spectral lines and jump to a higher energy level. We call it
The more the hollow cathode light is absorbed in the excited state, the higher the lead content in the solution. We can calculate the lead content in the solution according to Lambert-Beer's law..." Liu Zhiyun introduced the principle of atomic absorption in detail.
Understanding the principles in actual operation is very intuitive and gives people the feeling of seeing the entire development of the situation. Li Peicheng feels this way now. The principles he learned before can be understood immediately, and he can even understand the interference of spectral lines.
Recall some.
After the analysis was over, it was time to eat.
Li Peicheng walked slowly on the campus road with Liu Zhiyun, preparing to go to the cafeteria for dinner. Suddenly, his cell phone rang, and Li Peicheng saw that it was Lan Xiaoxue's call.
For some reason, Li Peicheng didn't like Lan Xiaoxue calling at this time. He always felt guilty when he saw this call.
He fell a little behind and answered the phone.
After all, Liu Zhiyun is a well-educated and highly qualified woman, so she would not interfere with Li Peicheng's phone calls.
"Boss, will you come back for dinner tonight?" Lan Xiaoxue's voice came from the phone.
Li Peicheng smiled hoarsely. It turned out that this was the case, and he felt quite warm in his heart. For people like him who had no parents since childhood, except for a few people, no one would remember his meals.
"No, I have an appointment tonight." Li Peicheng said with a smile.
Liu Zhiyun felt very good when she heard Li Peicheng say "I have an appointment tonight."
Li Peicheng and Liu Zhiyun didn't separate until eleven o'clock that day.
Because it was too late last night and we had another busy day moving today, by the time Li Peicheng returned to Wuzhuang, Lan Xiaoxue and the other three were already asleep.
There are three women living in the house, but it is different. The whole room is spotless. There are flowers placed in some places such as the coffee table, and small warm things placed in some corners.
As soon as Li Peicheng entered the room, he felt very warm.
Li Peicheng glanced around in surprise, then fixed his gaze on the second bedroom with the door closed, shook his head slightly, and smiled on his face.
Going upstairs, Li Peicheng was surprised to find that his sheets were neatly folded and there was a faint fragrance floating in the room. All the clothes in the bathroom were gone, including his shorts.
Li Peicheng hurried out of the bathroom, opened the closet and saw that everything was neatly arranged in the closet, exuding a fresh fragrance.

Sorry, the code was overturned yesterday and I had to rework it early in the morning, so I was late.
There are three updates today, and the second update will probably be at two or three o'clock in the afternoon.
