I recommend the Defiant Berserk System to you. It has a similar style and style to the Strongest Berserk Cheating System. I believe you will like it. The main character of the novel was equipped with a Berserk Upgrade System. He leveled up by killing monsters and killing people. He dominated the universe and specialized in dealing with all kinds of unconvinced people. I hope you like this fairy's recommendation. Muah ~😗
