[Waste material + counterattack + grassroots + fighting + world championship]
A good-for-nothing boy in high school, because of his weak body, was ridiculed by his classmates. He originally thought that he would do nothing and wait for death. By chance, he saw his friend being beaten and begging for help but could not do anything. He hated himself for being so useless. He made up his mind to change himself, protect the people he cares about, and gradually ascend to the top of the UFC championship.
This book is a tribute to my roommate who practiced martial arts, and part of the content is adapted from his real cases!
