After returning home, Song Haowen put down the textbooks and materials in his hand and went to the courtyard to see the magpies.

He stretched out a hand, and the big magpie from the tree reflexively flew to his hand and stopped, looking him in the eye

"Chirp" twice, as if to ask a question. He smiled at the magpie and shook his hand to throw it into the air.

It circled in the air, then landed on the tree, watched him and screamed again. Because of playing with magpies like this, Song Haowen's mood suddenly brightened.

He brewed a pot of green tea, and then sat in the octagonal pavilion in the courtyard to look through the textbooks and materials. He didn't learn this set of textbooks after he was reborn, and he read another set of textbooks when he was admitted to graduate school, so the content in it was still a little unfamiliar.

Fortunately, he had a solid foundation, and it only took half a day to master all the content of the textbook. In the evening, he took a special look at the textbooks and the exercises on the materials, and the simple ones were passed by at a glance, and the complex ones were calculated on the scratch paper, and by ten o'clock in the evening, he had gone through the five or six hundred questions in the two books, and he knew all of them by heart.

At this moment, he deeply felt the reason why teachers should prepare a bucket of water when they use a drop of water.

Thinking that he would meet his classmates as a teacher tomorrow, and thinking about the surprised appearance of his classmates, he couldn't help but laugh proudly.

After dawn, Song Haowen finished washing, put on a clean Mao suit and shiny cowhide shoes, smeared a layer of head oil on his hair, wore a red school emblem on his chest that marked the identity of the teacher, put the textbooks and materials in his briefcase, sandwiched them in his armpits, and swaggered into the school.

When I arrived at the tutor's office, I first said hello to Tutor Huiyan, and Tutor Huiyan couldn't help laughing when he saw his appearance, and this smile made Song Haowen blush.

Song Haowen walked to his desk and sat down, took out a teacup and made a cup of green tea, ready to enjoy it during the lecture.

It was the first time since he was reborn that he had brought a teacup into the classroom to listen to the lesson, and as a student in the past, he had never brought tea and drinks into the classroom.

Song Haowen sat in the office for less than twenty minutes, and Tutor Huiyan came over and called him to go to class together. He immediately agreed, picked up the briefcase, and followed Tutor Hui Yan to the seventh- and nineth-step lecture hall of the School of Physics.

He remembered that the School of Physics enrolled a total of 160 students this year, divided into two classes, A and B, with 80 students in each class, and he was originally in Class A.

The basic knowledge of freshman and sophomore years is taught in two classes; The juniors and seniors can take classes in groups according to individual electives.

However, "Quantum Mechanics" is an exception and is a compulsory course, so classes A and B are still combined together and take large classes in the lecture hall.

When Song Haowen followed Professor Hui Yan into the classroom, all the students felt strange, they didn't know what business he had to do in the classroom, or greeted him with a smile, or squeezed his eyebrows and grimaced, Song Haowen pretended to be calm, greeted the students politely, and then walked to the last row of empty seats in the classroom and sat down.

Squad leader Zhu Hongyu commanded: "Stand up!" The students shouted in unison: "Hello teacher!" Hui Yan said: "Hello students! Please sit down! Before the official class, Professor Hui Yan said with a smile: "Everyone still remembers Song Haowen, who just entered the classroom with me, right?" I would like to tell you the good news that Song Haowen has been approved by the school to stay in school as a teacher, and now serves as my teaching assistant. The whole classroom fell silent, and all the students were stunned by the news.

We're in our senior year, and you're a Ph.D., so we'll put up with it! Now it's the other way around as our teacher, Mom, find a crack in the ground for us to get into!

Hui Yan understood that the students couldn't get over it for a while, and comforted: "You don't have to feel embarrassed. The ancients said that those who have reached the master are teachers, and they are not ashamed to ask. If you have any questions about your study in this "Quantum Mechanics" course, you can directly ask Song Haowen, and I think he will give you a satisfactory answer...... Come, let us welcome our young and handsome teacher Song to the stage with warm applause! ”

"Wow!" The classroom burst into thunderous applause. Song Haowen's face was flushed, and he stood up and said to the class: "I won't be on the podium, just say a few words here: thank you for your care, help and encouragement to me all the time!" It is a rare fate to be able to learn and make progress together with everyone, and I will cherish it more...... I'm not used to being called a teacher yet. In the future, my classmates will still call me the best according to the habit of the past, what 'Xiao Song', 'Xiao Songzi', 'junior brother', 'little brother', 'genius', 'awesome'...... You can shout, I won't mind ......" Speaking of this, the whole class burst into laughter, and the atmosphere was obviously relaxed.

As soon as the first lesson ended, the whole class surrounded Song Haowen and asked him why he became a teacher, Zhu Hongyu and Na Renhua also wanted to come forward to ask about the situation, but unfortunately the front were all boys, and their twenty girls were not the opponents of one hundred and thirty or forty boys at all.

Fortunately, the ten-minute recess passed quickly, which made Song Haowen breathe a sigh of relief. However, this fifty-minute class felt that it was very short, and after the class, he was surrounded by his classmates again, and he couldn't get out at all.

In the end, he had to put down the dignity of his teacher and said that if he didn't let him go, he would pee his pants.

When everyone dispersed, Zhu Hongyu and Na Renhua walked up to Song Haowen and asked what happened. Song Haowen said truthfully.

Na Renhua said enviously: "Xiao Songzi, you stay in school to be a teacher, this is the top priority, we have to congratulate you." Song Haowen was overjoyed when he heard this, and felt that this was an opportunity to relieve the knots in each other's hearts, and immediately said that he would treat him tonight.

Zhu Hongyu was still hesitating, but was persuaded by Na Renhua and agreed. said, there are too few people to eat for the three of them, there is no atmosphere, and it is better to add a few more people.

Song Haowen said, this is easy to do, you are responsible for informing Gu Ziwei, and I am responsible for informing Wang Li, Yang Yuebing and Tian Yuxi, and everyone will gather at the Beijing Hotel next to the sales department in the evening!

They agreed. There were two classes in the morning, Song Haowen didn't have classes, he didn't go back to the office, but went home directly.

In the afternoon of one or two classes, Song Haowen went to the class again to listen to the class. In the afternoon, in the third self-study class, he stayed in the classroom to answer the questions of his classmates.

The students were surprised to find that his physics level was so high that they could only look up to the mountains.

After the third class in the afternoon, Song Haowen instructed the representatives of the two classes to put away the homework books and put them on his desk, and then he went back directly.

Not long after he arrived home, Zhu Hongyu, Na Renhua and Gu Ziwei came over together.
