I Just Became a Demon, but the System Asked Me to Correct Myself?

Qin Jiuyou practiced hard for three thousand years and was promoted to the rank of demon from outside the territory. A purple light group struck from the sky: "It is detected that the host's merit is negative, and the 'Light of Righteous Path' system is forcibly bound!" From now on—— Demonic Cultivator, system: "Merit +100, reward awe-inspiring righteousness (Note: Demonic Cultivator should be used with caution)." Destroy monsters, system: "Merit +10,000, reward "Great Mercy and Great Compassion Mantra" (Note: It has a soul-burning effect on demon cultivators)." Save the common people, the system: "Congratulations to the host, I am pleased to be awarded the title of 'Reincarnation of the Saint' (Note: The ancestor of the Demon Realm will form a group to hunt down the host)." Looking at the "reward" given by the system, Qin Jiuyou fell into deep thought. … There is no boundary between good and evil, and people's minds are fixed on right and wrong. Who says that a demon outside the realm cannot be the number one living bodhisattva in the nine realms? Novel also known as "The demon outside the territory, forced to save the common people at the beginning" "How come this demonic master has higher merits than a Bodhisattva?" "I practiced the devil's path, but became the light of the righteous path" "The system forces me to be a saint, but I am really a devil" "Cultivated to become a demon king, the system asked me to pretend to be a saint" "I just became a demon, and the system asks me to do one good deed every day?"
