In the afternoon, there were two diagnostic classes. When the bell for the class rang, Old Song entered the classroom with two books under his armpit and a thermos in his hands.

He glanced around the classroom. It seemed like there were almost a hundred students. His class had never been attended by so many students before, which made his self-esteem a little inflated.

The Old Song placed his book and thermos on the platform. After he swept his gaze majestically over the students, he cleared his throat and said in a clear voice, "Maybe some students already know about it, but maybe some do not. Let me explain it to the school."

Seeing the student's reaction, he continued: "Previously, Teacher Shi who taught everyone diagnostics was expelled from the school due to the lack of teacher Qualifications. Therefore, I will temporarily take over the class for you. Wait until the school recruits an even more outstanding teacher, then I will give you out this class. So during my teaching period, I hope my classmates will listen seriously and not waste precious learning time. What do you think? "

"Not much." The students replied in unison.

Old Song's smile froze, and his face immediately turned gloomy.

Once again sweeping a glance at the whole class, he said seriously, "You are all students of the Medical University. You can only obey the arrangements of the Medical University and have no right to pick and choose! "Now, open the textbook!"

"Report!" Teacher Shi never allowed us to open textbooks during class! " A student shouted from below.

"Report!" The Teacher Shi said that diagnosis is practice, and practice is to see a doctor. To teach a lesson according to the book, that is to say, showing that your standards are not high enough! "

"Teacher Song, didn't you teach the < Encyclopedia of Internals > before? That class you taught was pretty good. We love to sleep in your class. Why come here now to teach diagnostics? "There are specializations in the field of philosophy. You should do what you're good at and continue providing your students with sleep time?"

"Hahaha!"

The crowd burst into chatter and laughter. They did not place his seniority as an outstanding teacher in their eyes at all.

The muscles on Old Song's face twitched, and he suddenly grabbed the eraser, slamming it against the table. "Quiet! All of you, quiet down! Every teacher has their own teaching habits. Who says that only those who break away from their books are good teachers? That's Teacher Hun! He was a teacher who was irresponsible for his work! Without even reading a textbook or preparing a teaching plan, how can you say that he is a good teacher?

"No, I think the Teacher Shi is very powerful, right?"

"Mmm mmm, mediocre people just like to find excuses for their mediocrity."

"Flipping through textbooks and preparing teaching plans is a good teacher, then wouldn't a doctor who takes medical books to a doctor be a good doctor? Teacher Song, you have overturned my understanding towards these two jobs. "

"Teacher Song, you better not compare yourself with Teacher Shi. How pitiful are you going to be in such a comparison? I beg of you, please teach < Encyclopedia > this lesson. After all, I am tired now. "

"Hahahaha!"

Bang!

Old Song slapped the table, so angry that his face started to tremble.

"How did you all become students? Do you not understand the rules? Let me tell you, when I arrived, the dean of the department had already informed me that I had the right to persuade a student to leave, and also the right to record a great punishment on three students! To be honest, I'm not willing to go against you guys, but don't force me to cause trouble either! If I were to write it down for you, it would be a stain on your record for the rest of your life, and you wouldn't even be able to find a job in the future! "

Old Song pointed at the door of the classroom: "Those who don't want to attend my class, can leave, I won't stop you! "Rest assured, I will pass the final exam!"

Old Song had heard that Shi Lei had used this method to suppress this group of students before. Now that he had a good example, he wanted to try it out as well. He didn't believe that these students would dare to leave in front of him, no matter how brazen they were!

The answer was, yes.

Firstly, He Zhi, who was sitting in the first row, took off the earphones and stuffed them into her bag. Then, she carried her schoolbag and walked out.

Then, hualala!

The entire classroom was shaking, all the students were busy packing their things, doing everything they could to leave. Not a single one of them looked twice at Old Song.

In the blink of an eye, only one student remained in the classroom.

Old Song, who was in a state of shock, glanced at the student and so did the student.

Then he shouted at his friends that were leaving: "F * ck!" You bunch of bastards, even if you want to leave, bring me along as well. It's really inconvenient for me to do this … "

So it turned out that this guy's leg was wrapped in a cast and bandaged. He had fallen down a few days ago and had his tendons and bones injured, so he still hadn't recovered.

Shi Lei didn't go out today, he locked himself in his room and studied computer knowledge. Li Tongxi went to the Medical University to take two classes in the morning, and when she returned home at noon, she would stay at home to be a computer teacher.

Li Tongxi realized that Shi Lei was as talented in medical skills as he was stupid in terms of computers.

After explaining to him all afternoon, he still couldn't understand what computer viruses were and how computers could be poisoned.

A machine, not a human body, could be poisoned? Wasn't it making a ruckus?

If he was really poisoned, then wouldn't it be fine to just drink a bowl of medicine? If it didn't work, could he just give it acupuncture?

Li Tongxi patiently explained to him. In the end, he reluctantly accepted this setting and asked with a frown: "Since there's poison, someone must have poisoned it. I didn't see anyone poison the computer, did I?"

"…" Li Tongxi gritted his teeth and said, "Computer viruses are spread over the Internet. Where there is a network, there can be viruses."

"Then how do I know if I'm poisoned?"

"Fit an anti-virus software. If there's a virus invasion, the anti-virus software will remind you to delete the virus files."

"With the anti-virus software installed, I can stop being poisoned?" Shi Lei was surprised.

This thing is awesome!

Wasn't this equivalent to being immune to poisons? If the human body could fake an anti-virus software, then that would be too awesome!

Li Tongxi said dispiritedly: "Anti-virus software is also not omnipotent, you should save yourself the trouble of going on more websites in the future."

"I accidentally pointed it in …"

Li Tongxi waved his hand: "It's useless to explain to me. You should think about how to explain it to the students.

Shi Lei laughed awkwardly: "I already said I was poisoned, they understand, right?"

Right at that moment, the phone on the table rang.

The caller ID was He Zhi, so she didn't know why she was calling him at this time.

Without waiting for Shi Lei to speak, He Zhi's rather playful voice came from the other side, "Teacher Shi, you are quite popular in the teaching team, do you know this old master?"

"Old Master?" Shi Lei was puzzled: "I don't know him?"

"Don't know him?" Don't know you help her advertise? "Yesterday, you sent me such a large electronic poster. I thought you guys were very familiar with it."

"What advertisement?" What poster? " Shi Lei was very suspicious.

Li Tongxi could not bear to listen any longer, she lightly closed the door and went out.
