Naruto's most powerful cheating system

Story of: Naruto's most powerful cheating system

My name is Mo Xuan. I was originally just a high school student. I came to the world of Naruto inexplicably. Others are reborn with all kinds of BUFFs. The last thing I want is the Nine-Tails Chakra. Poor me, although I brought a system, this cheating system actually requires me to complete the task before I can get benefits. This is nothing, but do you dare to cheat me again with the damn task? You sneak attack Uchiha Itachi, attack Uchiha Shisui, challenge the third Hokage Sarutobi Hiruzen, do you dare to cheat again? The task rewards depend on your mood, the task difficulty depends on your mood, and whether you want anything depends on your mood. Is such a willful system not a discounted second-hand defective product?
