Violent Life After Rebirth

I was reborn in 2010. My only memories of my childhood were the days when I was the school bully, and my younger brothers were running rampant on campus and on the streets. I was reborn back to the childhood I longed for, and found that everything was different from before. In this world, everything is solved with force. There are many gangs, and the old gangs cannot challenge the new gangs. The new gangs fight with each other. To survive in this hateful world, violence must be used to solve the problem. This book is slow-paced, so please bear with me if you are a new author. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
