In his previous life, Zhong Yuan watched helplessly as his sister fought a desperate battle against a monster, ultimately perishing in the process.

When he opened his eyes again, the mysterious golden coffin allowed him to be reborn four years in the past, and also gave him a special ability: a 100% success rate in absorbing the abilities of other races, and the ability to reach the highest level.

Four years ago, my younger sister was only twelve years old. She had just been recruited by someone to enter the academy for people with superpowers and was about to embark on the path of a genius.

In order to prevent the tragedy from repeating itself, Zhong Yuan decided to go to the academy to accompany her.

Who would have thought that he, an auditor, would be bullied on campus as soon as he enrolled...

Zhong Yuan angrily exclaimed, "This is too chaotic! Luckily, I came to accompany my sister, otherwise I don't know how badly she would have been bullied!"

The crowd pleaded, "Zhong Yuan, please control your sister! She's completely lawless and won't let anyone live!"
