I just want to drop out of school

Welcome to the Classroom of Strength Supremacy + Dropping out
Others came here to study, but Bai Lan came here to drop out.
Bai Lan had just returned from a survival game in the Amazon rainforest when she received an invitation to take the entrance exam for Advanced Development High School.
Under the persuasion of his parents, he reluctantly participated in the written test and interview, just for fun. He thought it was a sure thing and he would definitely not pass the exam. In the end, he was admitted.
I wanted to drop out directly. As a result, the system awakened and gave me the ultimate task: as long as I did not drop out voluntarily and not because of my academic performance, I would be able to obtain [Invincible Luck] and [Extraordinary Physique].
Bai Lan was very tempted by the reward and wanted to give it a try.
He felt that even if the two ways of dropping out were blocked, it was still possible.
Later I found out that this school actually has something called a "withdrawal exam".
Steady!
result......
Jump into the face of a hidden BOSS, and the other party will worship him as their master;
Beat up the student council president, but was thanked by him;
Bullying a little girl, she said she wanted to date him;
He wanted to use his dark history to threaten his idol and cause public outrage, but the idol said he had helped him solve his problem.
He dropped out of school and blew himself up, and a group of people tried their best to protect him.
Why is it so difficult to drop out of school?
