The Villain at the Beginning, the System Asked Me to Be a Good Person

The biggest villain in the Qianyuan world went crazy in his training and when his soul was gone, Li Jiuye came through his soul. What! I traveled through time and became the great demon of the world's largest demon sect, and lost all my cultivation. Can I, a time-traveler, survive for three days? Fortunately, there is a system. "The host has done many evil things and is riddled with karma. It will not lead to a good death. Only by doing good deeds can the karma be eliminated and the path to enlightenment be achieved." The big devil has become a good person praised by everyone. Isn't this nonsense? But, is there something wrong with this system's understanding of good people and good deeds? "Li Jiuye, if you destroy my family, I will take your life today." An unknown opponent is provoking you. This person is extremely murderous and harmful to the common people. Saving him is an act of great kindness. The reward is a magic weapon and a golden elixir. It turns out that this is what good people do, and ideas are spread through fists. In this case, it is my duty to become a good person known to the world, Li Jiuye! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
