Invincible, I Own a Grocery Store

Lin Fei is in his early twenties and owns a grocery store in a small place called Shunfeng Town. The name of the store is 'Quanyou Grocery Store'. Originally he just wanted to run a grocery store quietly, but unexpectedly, peace got further and further away from him. He jumped from a small boss selling pills to the largest arms dealer. He is the source of turmoil, and he is the source of peace. The evil camp wants to kill him, and the righteous camp wants to protect him, but he is invincible, so why should he fear both sides?
