Bai Yueguang came back with the system

Yulin International Middle School.

At the entrance of the European-style campus, shaded by green vines and red bricks, there is an endless stream of luxury cars.

The fountain landscape pool is full of water vapor, and boys and girls in uniforms are walking on the bluestone paved road.

Yulin International School is a sister school to Wyvern School in the UK. The high tuition fees prohibit many families with an annual salary of millions. Except for the imported super gifted students, the rest of the students attending the school are either rich or noble.

Yu Qing stayed far away from Yu Yanchu in the car, as if there was some kind of virus on Yu Yanchu's body. When she got off the car, she was even more afraid to hide away and left quickly, forgetting what Yu's father told her to take good care of her sister.

In Class B, Grade 2, the bell has not yet rung, and the classroom is noisy.

Some demonstrated their golf skills to their peers, some read, and some applied lipstick in front of the mirror.

There were also several boys and girls wearing white shirts and green ties sitting at the table, sharing their holiday life and winking at each other.

"Did you hear that?"

"Is the illegitimate daughter of the Yu family coming back to school today?"

"Didn't Li Manzhi and He Zhen subdue her?"

"If you ask me, Yu Yanchu doesn't look like Yu Qing's sister at all. Last time I wanted to talk to her, she begged me like a lost dog."

A boy with a sharp mouth and monkey cheeks was very proud of himself. Apparently, being able to crush the Yu family under his feet gave him a lot of confidence.

"Qin Hang, you are so wretched. If Yu Yanchu didn't beg for mercy from you, you would have put your hand into her underwear." The boy next to him said with disdain.

"Yu Yanchu is still pretty, but it's a pity that Ning Zhuoyi suddenly barged in, otherwise..." Several boys headed by Qin Hang all laughed obscenely, and several girls looked disgusted.

"You are so disgusting."

"Yu Yanchu is here."

Someone shouted, and they looked at the door leisurely.

Ji Heng, who was sitting at the door, lazily raised his head when he heard this, resting his forehead with one hand and spinning his pen boredly.

Yu Yanchu was carrying his schoolbag and just stepped into the classroom door when one of his feet stuck out unexpectedly.

She couldn't dodge, and staggered to the ground. The white cotton socks wrapped her slender legs, and were exposed from under the navy blue uniform skirt. Fortunately, it was a non-slip floor tile, otherwise she would have broken her skin.

At this time, a slender hand stretched out in front of Yu Yanchu, and she looked up.

The young man was thin and had a shallow scar on the right corner of his eye, which gave his already handsome face a more ruthless look. He seems very personable, but his eyes are extremely cold.

"Why are you so careless?"

【Ding--】

[The system has detected a key person. 】

[Name: Ji Heng, age: 17 years old, identity: heir to WJH Entertainment, your ex-fiancé. Engaged to Yu Qing after you went missing. He has a ruthless and vengeful personality and protects Yu Qing from campus to the entertainment industry. At this time, Yu Qing is full of malice towards you. 】

[The strategy character has appeared]

[Ji Heng’s favorability: -2/5]

Yu Yanchu sneered and reached out to hold Ji Heng's hand. Before he could react, he stood up hard and pushed his knee hard against Ji Heng's lower body.

Unexpectedly, Ji Heng hit his belly on the table and groaned. The group of boys and girls watching were shocked.

Yu Yanchu patted the non-existent dust on his hands.

"Why are you so careless?"

Without waiting for Ji Heng's reply, he turned around and left, sitting down as if nothing had happened.

[Ji Heng's favorability -1, current favorability -3/5]

Ji Heng was about to get angry when the teacher came.

He sat back on his seat angrily and gestured to Yu Yanchu to wipe his neck.

Yu Yanchu showed no sign of weakness and pointed at his eyes with his index and middle fingers, indicating that he would wait for him.

The students in the same class were whispering excitedly.

If Yulin Middle School has F4, it must be Ji Heng, Ning Zhuoyi, Lin Mingjia and Li Ran.

These four people are handsome and have superior family backgrounds. They are also at the top of the pyramid in Yulin where rich children gather.

Ji Heng is the most vindictive and cruel among the four of them. Yu Yanchu landed in Yulin at the beginning of his second year of high school. It was the first time that he acted so tough when being bullied. Now he was in for a good show.

Yu Yanchu was not in the mood to care about F4 and A5. In her eyes, they were all a bunch of brats.

High school classes were still so boring. Yu Yanchu held his head and fell asleep after listening for a while.

"Yu Yanchu. Come up and do this question."

"Yu Yanchu?"

Everyone looked over, and Ji Heng gloated and laughed.

The deskmate who arrived at an unknown time pushed Yu Yanchu several times, and Yu Yanchu slightly moved his eyelashes, opened his eyes, and faced the young man's dark eyes.

【Ding--】

[The system has detected a key person. 】

[Name: Lin Mingjia, age: 17 years old, identity: Mayor Lin’s youngest son, your deskmate. Melancholic and kind-hearted. In the original text, Yu Qing grasped his weaknesses of guilt, depression, and loneliness and firmly grasped him. Lin Mingjia finally committed suicide in the cold winter due to deepening depression. 】

[The strategy character has appeared]

[Lin Mingjia favorability: 0/5]

Under Lin Mingjia's long and thick eyelashes, his eyes are pure and black, clear and charming. A diamond earring on his left earlobe shines brightly, making his perfect face even more dazzling.

Ning Zhuoyi and Ji Heng are already the most handsome men of their age. Compared with their heroic appearance, Lin Mingjia's beauty is more melancholy and fragile.

Even the well-informed Yu Yanchu who had passed through the grass could not help but sigh. It was a pity that such a young man from Zhilan Yushu ended up like this.

Seeing Yu Yanchu staring at him, the young man smiled and the melancholy in his eyes dissipated.

"The teacher calls you."

Only then did Yu Yanchu react. She glanced at the textbook at her deskmate, and Lin Mingjia's skeletal hand gently clicked on one of the formulas.

Yu Yanchu stood up slowly and recalled while walking.

Yu Yanchu hadn't read mathematics in many years. She looked at the questions on the blackboard.

已知椭圆C1与双曲线C2有共同的焦点F1,F2，其中F2为右焦点，两曲线在第一象限的焦点为P,离心率分别为e1，e2，若线段PF2的中垂线经过点分，则1/e1+1/e2=（？）。

Yu Yanchu slowly wrote 'solution' on the blackboard and didn't move for a while.

Whispers and jeers began to be heard below.

The teacher crossed her chest and was ready to let her go down.

At this time, Yu Yanchu started writing.

林明嘉指的公式应该是椭圆和双曲线的定义公式。设半轴为a1，a2，把公式往上一扔，1/e1+1/e2=2。

Yu Yanchu threw away the pen, turned and left.

The teacher nodded.

"Although this classmate fell asleep in class and the process was not fully written, it seems that he has mastered the knowledge points I usually teach."

Ji Heng sighed regretfully after hearing this.

-

Yu Yanchu felt that his endurance had been rising sharply since his rebirth.

During the recess, she just went to the toilet, and her desk pocket was messed up.

Opening the textbook, Yu Yanchu looked gloomy - the inner pages of the book were scratched, and someone had written "little mouse" in characters that looked like a dog crawling.

Lin Mingjia was very surprised when she came back from a break, and then took out her textbook to share with her.

It was too obvious for two people to read the same textbook. Teacher Qiu walked towards them, "Who didn't bring a textbook?"

The group of people who were talking about Yu Yanchu in the morning winked at each other and gloated about his misfortune.

Mrs. Qiu was famous for her bad temper and strict teaching. She was also a troubled person in Yulin Middle School where there were many aristocratic families.

No matter who doesn't abide by classroom disciplines or forgets to bring textbooks, he will be punished by going out to stand. Who knows that she has a profound background.
