System Rebirth Death Assassin

(This is my first book, and it is poorly written. I hope readers can express their opinions. I will refer to your suggestions!) Well, this book is probably about a little miser who was stabbed in the back by a friend in his previous life. Then he was reborn (ah, yes, this guy is the protagonist after all), and was reborn before the start of the game - Infinite Reincarnation. Then this guy entered the game and found that the god-level profession in his previous backpack was still there. Well, he successfully changed his profession to the Thorn of All Things. And then it's just like those system game articles, about killing BOSS instantly, beating countless numbers... Mainly because this thing is so easy to write, you can just copy it casually. Huh? What, you mean the back? Well, in the back... It's gone, yes, it's gone. (You have to believe what I wrote. You are awesome. I wrote the above stuff randomly. You have to read it yourself, okay?)
