Li Peicheng just wanted to open his mouth to ask Liu Zhiyun what happened, but Liu Zhiyun had already turned around and went back to the office sadly.

Seeing this, Li Peicheng had no choice but to put down the work in his hand and follow into the office.

"Who messed with you Zhiyun?" asked Li Peicheng.

"It's you, it's you nasty guy!" Liu Zhiyun curled her mouth in anger.

"I, what's wrong with me?" asked Li Peicheng innocently.

"Let me ask you, where did you go last night? Why didn't you come to dinner with me? Why didn't you go to the evening self-study? Why didn't you call me?" Liu Zhiyun looked at Li Peicheng and asked again and again.

Li Peicheng couldn't cry or laugh when he heard this, when did he even need to report these things to Liu Zhiyun. However, Li Peicheng could see that Liu Zhiyun's attitude was very serious, not like being vexatious or joking.

"I was in a bit of a hurry last night, so I didn't care about you!" Li Peicheng replied. He didn't want to tell Liu Zhiyun about Lan Xiaoxue and them, he had an intuition that it would be better not to tell her about it.

"In the evening, how about we have dinner together and study on our own in the evening?" Li Peicheng continued.

"Who is rare!" Liu Zhiyun's anger had already disappeared a little, and she finally realized that she seemed to be a little unreasonable, and replied with a slight blush.

Li Peicheng saw that Liu Zhiyun's cheeks flushed slightly, and she felt very beautiful, and couldn't help but be a little stunned.

"Don't do the experiment yet, what are you standing here looking at?" Liu Zhiyun saw that Li Peicheng had been staring at her, she was very happy in her heart, and her frustration had long since disappeared.

"Then you're not angry?" asked Li Peicheng.

"Who is so boring and angry with you?" Liu Zhiyun couldn't help but be angry and shy when she saw Li Peicheng mention what happened just now.

Seeing this, Li Peicheng smiled, turned around and walked out of the office.

After Li Peicheng walked out of the office, Liu Zhiyun held her chin with her hands, looked out the window in a daze, and felt that her heart was beating fast.

Am I in love with him? Is this love? Liu Zhiyun asked herself.

But the shadow of the family hung over her mind like a nightmare that could not be shaken off. Soon Liu Zhiyun's eyes showed a sad and melancholy look, because she thought that even if Li Peicheng fell in love with her, this love would not yield anything.

"Now that you've thought about resisting to the end, what are you afraid of? Even if you can't resist in the end, you should be happy during this time. Liu Zhiyun's words flashed through Li Peicheng'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 walked out of the office and returned to the laboratory, and when she saw the back of Li Peicheng busy in the laboratory, she couldn't help but smile on her face.

Many people in the laboratory saw the smile on Liu Zhiyun's face, and this may be the first time they have seen Liu Zhiyun's smile. The boys were stunned, their eyes were so hooked that they couldn't turn at all, and the girls saw it, and they died of envy and jealousy, why didn't they have such a moving smile?

"Peicheng, let's stop the experiment here in the afternoon!" Liu Zhiyun walked up to Li Peicheng and said.

"Why?" asked Li Peicheng.

"I want to test the heavy metal content of a batch of samples digested yesterday, don't you want to learn how the instrument works?" Liu Zhiyun said coquettishly.

"Oh, you're going to get on the instrument today!" Li Peicheng said with some surprise.

"Hmm!" Liu Zhiyun nodded.

There are courses in instrumental analysis, which are in university courses, and Li Peicheng has also worked hard, and he has also studied the principles and other things. But the actual work is basically nothing, the teacher just took them to visit the instrument and introduced the structure of the instrument.

Originally, the Department of Resource Science also had a Tajimadzu atomic absorption, but due to poor management at the beginning, the number of users was relatively mixed, and the failure rate of the instrument was relatively high. Later, it was changed to a special person in charge, and it was rare for scientific research assistants like Li Peicheng to have the opportunity to work in person.

"Put the lead hollow cathode lamp on it first, preheat and stabilize for a while. Liu Zhiyun commanded Li Peicheng to work step by step.

"The lead hollow cathode lamp is used to emit characteristic spectral lines, and the characteristic spectral lines emitted by it excite the ground-state lead atoms in the ignited gaseous solution, and the lead atoms absorb the characteristic spectral lines and jump to a higher energy level, which we call the excited state. The more the hollow cathode light is absorbed, the higher the lead content in the solution, and 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 principle in the actual operation is very intuitive, and it will give people the feeling that they seem to see the whole development of the situation, and Li Peicheng now has this feeling. The principles I have learned before can be immediately integrated, and even some of the interference of spectral lines can be recalled.

After the analysis, it was time to eat.

Li Peicheng accompanied Liu Zhiyun to walk slowly on the road to campus, preparing to go to the cafeteria to eat. Suddenly, the mobile phone rang, and Li Peicheng saw that it was Lan Xiaoxue's phone.

I don't know why, Li Peicheng didn't like Lan Xiaoxue calling at this time, and he always felt weak when he saw this call.

He was a little behind and picked up the phone.

After all, Liu Zhiyun is a well-educated and high-quality woman, and she will not interfere with Li Peicheng's phone call.

"Boss, are you coming back for dinner in the evening?" Lan Xiaoxue's voice came from the phone.

Li Peicheng smiled dumbly, it turned out that this was the case, and he felt quite warm in his heart, people like him who had no parents since he was a child, except for a few people, no one would remember his meal.

"No, there's an appointment for the evening. Li Peicheng said with a smile.

Liu Zhiyun heard Li Peicheng say "I have an appointment in the evening", and she felt very good.

On this day, Li Peicheng and Liu Zhiyun did not separate until eleven o'clock.

Because it was too late last night, and it was another busy day to move today, so when Li Peicheng returned to Wuzhuang, Lan Xiaoxue and the three of them had already slept.

It was not the same that there were three women living in the house, the whole room was spotless. Some places such as coffee tables are placed with flowers, and some corners are placed with warm little things.

As soon as Li Peicheng entered the house, he felt very warm.

Li Peicheng glanced at it in surprise, then fixed his gaze on the second bedroom with the closed door, shook his head slightly, and a smile appeared on his face.

Upstairs, Li Peicheng was surprised to find that his sheets were neatly folded, and there was a faint fragrance wafting in the room. The change of clothes in the bathroom was gone, including his shorts.

Li Peicheng hurriedly went out of the bathroom and opened the wardrobe to see that it was all neatly arranged in the wardrobe, exuding a fresh fragrance.

I'm sorry, yesterday the yard was overturned, and it was reworked early in the morning, so it was a mistake.

Today's third watch, the second watch is estimated to be at two or three o'clock in the afternoon.
