Chapter 4

As expected, Yan Jin was late again the next day.

When Xiao Niang and the others were doing morning exercises, Yan Jin was drinking soy milk at the breakfast shop next to the school gate.Most of the school gates are closed, leaving only a small gap.

Yang Wenbo stood there majesticly, giving those late students a big blow from time to time—this became the best accompaniment for Yan Jin's breakfast.

Seeing that he wasn't in a hurry, the proprietress who bought breakfast wondered, "Student, are you from No. [-] Middle School?" Yan Jin took out a piece of paper and wiped her mouth carefully, "Yes, Auntie will help me get it again." Two fritters."

The proprietress turned her head and quickly wrapped fried dough sticks for him, "Aren't you afraid of being late?"

Yan Jin took the fritters, paid the money and walked to the door and said lightly: "Of course I'm not afraid, I'll go in..."

Yan Jin carefully walked along the white school wall for a short distance, and climbed up a low wall that was somewhat damaged and gray with ease.He first tossed in the light and empty schoolbag, propped his hands on the wall, and climbed over the wall three times, five times and two times.

"□□Mission, successfully completed!"

Yan Jin took out a fried dough stick that was fried golden and crispy, and raised her eyebrows with pride.He didn't go directly to the teaching building, but to the playground where the run was about to end.

Yan Jin gnawed the deep-fried dough sticks slowly, admiring the students' running postures upside down.

"Tsk, your food is delicious." Yang Wenbo came back from the gate at some point, and immediately saw Yan Jin sitting next to the football field not far from the playground.

"Where did you come in today?" Yang Wenbo snatched another deep-fried dough stick from the bag and gnawed it with his bare hands.

"Hey! That's my breakfast!"

"Come on, you, come here when you're full. I stood at the school gate for 10 minutes, and I saw you ate for 10 minutes."

Yan Jin chuckled, "You have the strength to study when you're full."

Yang Wenbo gave a "tsk" and shook his head: "The words 'learning' come out of your mouth, it is an insult to it." Yang Wenbo wiped the oil on his trousers casually, and Yan Jin's eyelids twitched. Jump.

"By the way, here comes the replacement for the teacher who ran away in anger. This time, if you are like last time, you won't be punished so much."

Yan Jin nodded and smiled, "That's it, that's it, Mama Yang, go slowly."

Yang Wenbo watched Yan Jin walking unsteadily in the direction of senior one (five), and took out his cell phone from his pocket.

"Hi, Xiao Xie, what's the matter?"

Xie Ting's anxious voice came from the other end of the phone: "Hello, Team Leader Yang, I, I can't find my way..."

Yang Wenbo wondered: "Hasn't Xiao Xie been to Nineteen Middle School? Just turn on the navigation and you will be there."

"Okay, it's expected to arrive in 10 minutes, it may be late..."

"It's okay, I'll support you, try to hurry up."

"Okay." Xie Ting hung up the phone and stuffed him back into his pocket, feeling a little ashamed: "Hey, I'm still going to be late, this is the first day."

A little earlier than Xie Ting estimated, he arrived at No. 15 Middle School in only [-] minutes.It happened that the second preparatory bell was ringing, Xie Ting got out of the taxi in a hurry, packed his bag on his back, and rushed into the school gate.

The former Nineteenth Middle School had a glorious history. Even though it is now in decline, the campus still reveals a kind of scholarly atmosphere.The football field has been newly renovated, and you can smell the smell of plastic turf that hasn't completely dissipated when you walk closer.

There is a small rockery in the middle of the school, and water is gurgling downwards. The water droplets splashed on the stones to form a thin mist, which dispersed into faintly colored halos under the bright morning sun.

The school is very simple, there are only two teaching buildings - junior high school and high school.

Xie Ting secretly compared the [-]th Middle School with the high schools he had attended before, and deeply felt the beauty and generosity of the environment of the [-]th Middle School.

He walked quickly to the senior high school. Due to time constraints, he didn't go to the grade office to report, but went to the "Senior Class [-] ([-])" that Yang Wenbo told him.I passed several classes along the way, and I could see the students and teachers inside from the doors they didn't close tightly.He finally reached the second (fifth) class of high school, and through the heavy door, he could hear unreal voices from inside.

"...Students, we should respect our teachers, care for our classmates, and get along with each other in a friendly way. We must never follow the example of a certain classmate. This is unwise and irrational. We must actively communicate and improve our relationship... ..."

Xie Ting heard a few secretive voices of laughter in the class, followed by Yang Wenbo's reprimand: "Laugh, you guys! This is a very serious matter, and the impact it will bring will be very bad, and it may affect your future. Life brings stains! But I see you admire it, don't you?"

Yang Wenbo was a little tired of scolding, he didn't know whether it was disappointment or anger and heaved a long sigh.

Xie Ting, who was listening to the corner outside the door, knocked on the door at the right time.Yang Wenbo left those smoking kids who made him angry, and opened the door a crack.

"Is it Teacher Xiao Xie?" Xie Ting was a little nervous, and nodded cautiously.Yang Wenbo opened the door completely, and white sunlight instantly filled the classroom.

He brought Xie Ting in, and knocked hard on the blackboard: "Stop everything! Stop putting on makeup, playing with mobile phones, and sleeping!" He cleared his throat, "This is your new math teacher, Teacher Xie, He is not a few years older than you, so get along well and don't make trouble. Teacher Xie, I will leave them to you, you must protect yourself well."

Xie Ting thought: "Why does it sound like a corpse farewell mode?" Xie Ting shook his brain that had been smashed into a lump, and smiled slightly: "Hello students, my name is Xie Ting, which means the one by the water. "

Xie Ting glanced around below, and found that most of the people had stopped what they were doing, and looked at him with a pair of small, confused eyes—except for a few who were living in a dream.

Xie Ting nodded in satisfaction, "I will be your math teacher in the future, the long-term one."

The girl whose makeup was stopped by Yang Wenbo interjected: "Mr. Xie, you look so good-looking. I can't describe how good-looking you are. It's just a little bit worse than our Brother Ban Jin."

The people in the surrounding circle laughed secretly.The corners of Xie Ting's lips curled up, the corners of his eyes slightly curved, and the lenses looked sparkling in the sun.At first glance, it looks like a high school student without a school uniform - warm and clean.

He also followed them with a smile and said, "Oh? Then I want to see which handsome guy is a little bit more handsome than me." Looking around the class several times, he still didn't see the handsome guy who was a little bit more handsome than him. Dot" handsome guy stood up.Xie Ting had a gentle and soft smile on his face, "It's okay, get up and show me. I'm not an old witch who would be jealous of your beauty."

The whole class burst into laughter.There was a boy who laughed especially hard and stood up, panting and said: "Xie, Teacher Xie, it's not that he's afraid of your jealousy, he's right next to you, he's asleep!"

Xie Ting looked towards the side of the podium in a blind spot in his line of sight, and sure enough, he saw a boy lying on the table, having a friendly talk with Duke Zhou.Xie Ting stared at him for a few seconds, then tapped lightly on his desk.

It stands to reason that this volume is enough to wake up a light sleeper, but the boy lying on the table seems to be in a deep sleep, showing no signs of waking up.Xie Ting squatted down, observed him carefully for a while, and then pushed him with his hands.

"Student, wake up, let me admire your heroic appearance."

Maybe Xie Ting pushed him too much, or maybe the students laughed too much. The little boy lying on the table finally made some movement, raised his head, and there was a slight indentation on his face—— — was pressed by the headphone cable on the table.

Yan Jin played review last night until 02:30 in the morning, and finally caught the opportunity to go to bed early.

Who knew that this morning was extraordinarily noisy, the first time he was disturbed, he was already half awake, but he was willing to lie on the table for a few more classes.In a daze, he heard a voice that seemed to have heard it whispered a word in his ear——

He was shocked.Most of the drowsiness has also faded.
