Zhou Litao invited him to dinner. He couldn't drink much wine, but he still drank two bottles of beer with Su Yun. Seeing that he was too drunk, Su Yun directly threw the goods aside.

While drinking with Chang Yue, Su Yun said about the man he met after the operation. Although it was only speculation, people were still stunned.

"Su Yun, did you see him with a knife?" Zheng Ren suddenly asked.

Su Yun shook his head with a dazed expression.

"I didn't see it either. I just feel that this situation is somewhat similar to that encountered by Chang Yue in Haicheng." Zheng Ren said, "but I don't think the man's fun is here. I hope the child can be safe in the future."

"Boss Zheng, do you think this is revenge on the society?" Zhou Litao asked.

"Boss, is it too much for you to use the word fun?" Su Yun said contemptuously.

Everything is just a guess. It's impossible to call the police because of a guess. It's just that Zheng Renhe and Su Yun are more inclined to that man on purpose. Everything is considered from the darkest point of view.

Said a few words, changed the topic, and talked about something else. Until this time, the atmosphere eased a little.

Although Zhou Litao has been out of hospital for nearly a month, he still hasn't come out of the haze. After eight o'clock, he was restless.

Knowing that he was ill, he was uneasy in the emergency department for a long time. Only when you hear the messy sound outside can you have a safe sleep. Recently, Zhou Litao has to sleep with the TV on, otherwise he can't sleep well at all.

At first, when Zheng Ren and Su Yun went to perform the task, Zheng Ren was the same as Zhou Litao.

This is a kind of disease, called inpatient syndrome. It will be fine after a period of time.

The sunspot is still at home. It's a worry. At nine o'clock, Zheng Ren broke up.

Su Yun carried his mobile phone and didn't know who he was talking to all the way. Just at the door of his house, he let out a sigh and stopped his steps.

"What's the matter?" Chang Yue asked.

"I had parasite class today. This is." Su Yun said something thoughtless.

Zheng Ren understood, but he was curious about how students could contact Su Yun so late.

As a professor, Zheng Ren has no sense of responsibility. Su Yun was keen on this. At first, he went to the Affiliated Hospital of Medical University to borrow a ladder classroom to teach the children. After that, he accepted the invitation and occasionally went to two classes.

"Some students think they have parasites?" Zheng Ren asked.

"Well, on the way to the emergency department."

"What did you say?"

"He said he found insects and took them with him." Su Yun suddenly smiled, "you said a boy, did you eat the insect egg capsule?"

"No." Zheng Ren shook his head.

Su Yun said as he dialed a phone.

"Miss Li, did you sleep?"

"Who asked you to drink? What time is it? There will be an operation tomorrow. Our boss is fierce, super fierce!"

"No nonsense, let me ask you something. Have you told the students about Ascaris lumbricoides recently?"

"Hahaha, I guess that's it. I see."

"Hang up. Make an appointment another day."

With that, Su Yun hung up the phone and said proudly, "I'll tell you. I just finished my parasite class today."

Xie Yiren and Chang Yue went home first. Zheng Ren was a little curious and followed Su Yun to the emergency department for a look.

Generally speaking, it is normal to feel uncomfortable when you learn something in class. But they are all similar to hysteria, a purely imaginary disease.

Even if you don't care, it will soon be fine. For example, the mass incidents of vomiting and diarrhea among students on a large scale encountered before are extremely rare and may not be encountered once in many years.

Similar to just received a phone call, there are many single events, but hysteria is mainly due to the discomfort of various organs. And in parasite class, there are parasites after listening to one class? This is weird.

Hysteria has parasites, which Zheng Ren doesn't recognize. He thinks there must be other problems.

In addition, he met a patient who ate Ascaris egg capsule yesterday. He was also curious about what happened to the student.

When he came to the emergency department, two students looked at him eagerly. One of them was nervous and the other girl was constantly comforting him.

"Miss Su! Miss Su! This side!" When the girl saw Su Yun, her excitement level was + 18 and she threw down her little boyfriend on one side.

That's right. The current situation fully meets Zheng Ren's expectations.

Either the girl found the roundworm, or the one in front of her. In Su Yun's world of women's friends, there is no such thing as running to the hospital in the middle of the night for a male student's Ascaris.

It's not a fatal emergency. If you change a boy, just bear it and go to the clinic tomorrow.

"What's going on?" Su Yun asked.

"My boyfriend... Said the worm." The girl gestured with her fingers, about 6-7cm long.

"OK?"

"Er... It should be, Zhang Kai, you come!" Cried the girl.

The boy looked flustered and hurried to Su Yun with a ball of toilet paper in his hand. Although flustered, he was very polite and didn't forget to bow first and said hello to Mr. Su.

"What's going on?" Su Yun asked directly.

The boy was a little shy. He said slightly embarrassed, "I just defecated in the bathroom. I felt that my stool was not clean. There was always something hanging on... Later, I touched it through toilet paper. It was an insect..."

"There's nothing to be afraid of." Su Yun said contemptuously, "it's Ascaris lumbricoides. Just see it clearly and throw it away. Your teacher didn't teach you what Ascaris lumbricoides look like? Go back and check. There's nothing else. Just take some insect repellent."

"Miss Su, I'm afraid I'm wrong. I want to... Come to the hospital." The boy lowered his head in shame and whispered, "didn't you tell us you were ill and wanted to come to the hospital?"

"That's true. Did you take out the bug later?"

"Well, there's a head in the back. It doesn't look like a roundworm. I pulled it out. It's a little dirty. I'm sorry. Would you take a look?" The boy apologized again and again.

"What's the matter? When you get to the clinic, there will be more disgusting things." Su Yun said with a smile, "open it for me."

"I didn't dare to see it. When I pulled it out, I quickly wrapped it in toilet paper. I was worried that it might run away."

With that, the boy opened the toilet paper in his hand layer by layer.

The bag is called a tight one. It hasn't been fully opened yet. It smells straight to the nose.

Su Yun didn't hide and looked at the toilet paper seriously. As he said, there are too many stems of excrement, urine and fart in clinic. I don't bother to mention it at all.

Zheng Ren is a little serious. Insects can touch his head. What the hell is that? Normally, human parasites should not have obvious heads. Most of them are creatures similar to earthworms.

Until he opened the last layer, Zheng Ren was stunned when he saw the things wrapped in toilet paper, and then he lost his smile.
