This situation occasionally happens on weekdays.

She also knows Professor Liu's physical condition very well.

Zheng Yun can be said to have genuine admiration and respect for Professor Liu, and Professor Liu also has the intention to support Zheng Yun.

Zheng Yun, who originally came from the countryside, treated Professor Liu as a relative.

Whenever Professor Liu needed to be hospitalized for treatment, Zheng Yun was usually the one who stayed by his side and took care of him.

Taking care of the old professor is both troublesome and laborious, and Zheng Yun, who is devoted to Professor Liu, often has no time to take care of his own food and daily life.

Thinking of this, she couldn't help but feel a little pity for Zheng Yunduo.

However, what she did not expect was that when she hurried to the school clinic, she was told that Professor Liu had never been there.

This made her feel very confused and puzzled: Professor Liu is a highly respected academician in the school, but now not only is he missing from his home, but he has also been searched everywhere in the school and the school clinic but to no avail.

She was worried about her boyfriend Zheng Yun and also concerned about Professor Liu's safety. She did not dare to delay for a moment and immediately reported the abnormal situation in detail to the department head.

Upon hearing this, the department head asked someone to go to Professor Liu's house and knock on the door, but there was still no sound. On the way back, he happened to meet Liu Mu and asked Liu Mu where Professor Liu had gone.

Liu Mu thought it was the same as before, that he wanted to see his father for scientific research, so he replied, "My father feels a little dizzy, so he went to the school clinic with Zheng Yun."

The department head was puzzled when he heard this. "Student Liu, when did that happen?"

Liu Mu pretended to recall, thought for a moment and said, "That happened around noon today. My dad went home to get some information and then said he felt a little dizzy.

Zheng Yun happened to be there and said he would accompany me to the school clinic."

The department head exclaimed, stamping his feet. "They're not in the school clinic, so where are they?"

Liu Mu then realized that the department head had already gone to the school clinic. He pretended to be panicked and said, "Oh, where did he go?

Could it be that my dad was too weak and in so much pain that he went to another hospital for treatment?

I’ve been to see a doctor a few times before.”

The department head thought what he said made a lot of sense.

As for an adult, nothing will happen.

The department head hurriedly instructed, "If you find your father, please tell me. Professor Liu is a key figure in our department, and we can't let him go wrong."

Liu Mu replied respectfully, "I understand, Director. I will contact you when my dad comes back.

Don't worry too much, this isn't the first time I've sought medical treatment outside the home."

After hearing what Professor Liu’s son said, the department head left with the teachers.

Liu Mu knew that this matter could not be delayed any longer, he had to get the money quickly and leave quickly. Otherwise, something bad would happen sooner or later.

He wanted to get the money and leave safely.

When he was returning to the house, he met Liu Yun's girlfriend Shu Hua again. She was waiting anxiously at his door.

Seeing Liu Mu coming, she hurriedly stood up and asked anxiously, "Classmate Liu Mu, do you know where Zheng Yun went?"

It was already dark by now.

Liu Mu shook his head, his face showing a bit of anxiety, "I don't know either. I'm also anxiously looking for it."

Shu Hua said, "That's right, I was worried that he might be too busy, and I wanted to come over to help, but I didn't see him.

Where did he go with Professor Liu?

Liu Mu comforted him, "Don't worry, you see there are no lights on in my house, so he is definitely not at home.

Two grown men, they definitely can’t get lost.

I went to several hospitals to ask in the evening.

Don't be in a hurry.

Well, you go back to the dormitory first, and I’ll let you know when I find the person.

What's the address of your dormitory?"

Liu Mu thought so, and then thought again.

If it weren't for Shu Hua looking for a boyfriend everywhere, perhaps no one would know about Professor Liu's disappearance?

After all, when those people from the school came to ask questions, he could just dismiss them with a few words.

Shu Hua was about to give her address when he hurriedly asked, "The dean is here today. Did something happen?"

Shu Hua didn't put on guard against Liu Mu and told him everything, "Yes, I couldn't find anyone today, so I went to the department head, but they couldn't seem to find anyone either, and I got even more nervous.

Will Professor Liu be okay?"

Liu Mu thought to himself, and just as he expected, it was the female classmate in front of him who almost exposed him.

If she hadn't been anxiously looking for Zheng Yun everywhere, how could she have attracted those people from the department?

If she didn't get any news at night, she might have to alert the security department.

Thinking of this, Liu Mu's eyes rolled and he changed his mind instantly. He smiled and said to the female classmate, "How about this? Seeing that you are so anxiously waiting for Zheng Yun to arrive, why don't you go to my room and rest for a while and wait."

Shu Hua hesitated for a moment when she heard this, but when she thought about how she had indeed been waiting here for a long time and that she had been to Professor Liu's house several times before and was quite familiar with Liu Mu, she stopped hesitating and quickly nodded in response, "Thank you so much, Liu Mu!"

After saying that, he followed Liu Mu towards his house.

Liu Mu took out his key and opened the door. He turned on the light and the hallway suddenly became bright.

Shu Hua didn't feel anything unusual at all, so she followed him in.

Liu Mu turned on the lights in the living room one by one and invited Shu Hua to come in and sit down. "Xiao Shu, go sit there."

As he was speaking, the phone rang again.

This time it was the principal who called.

When Shu Hua heard the phone ringing and couldn't help, she sat down on the sofa obediently.

As for Liu Mu, when she heard the word "Principal", she became a little nervous and helpless. She straightened her waist and moved her buttocks outward.

She was just an ordinary student with little experience, and she always felt respect and fear when she heard the name of the principal.

Liu Mu answered the phone, and the principal's serious voice came over, "Xiao Liu, the whole school is paying close attention to Professor Liu's situation. If you get any news, you must inform the school immediately."

Liu Mu nodded repeatedly and said that he was also preparing to look everywhere.

After hanging up the phone, he turned to look at Shu Hua, a barely perceptible ruthlessness flashing in his eyes. But in an instant, he regained his usual gentle and graceful demeanor.

If he hadn't made that phone call just now, Shu Hua would have been knocked unconscious by now.

He only wants money, not lives.

Now the principal has been alarmed. Maybe someone will come to express condolences tomorrow. By then, it will be too late.

Besides, his goal is to retreat in two days.

Whether an old man over sixty can survive depends on the girl in front of him.

Liu Mu smiled and said, "Xiao Shu, you and Zheng Yun seem to be in a good relationship. How long have you two been dating? When do you plan to get married?"

Shu Hua was startled by his sudden question. "I, I've been dating Zheng Yun for over a year, but we haven't planned on getting married yet."

“I see you are so nervous about him, you are indeed a good girl.

If Zheng Yun is in trouble, would you dare to sacrifice everything for him? "
