Once the supreme powerhouse who ruled the Demon Realm, he grew tired of endless slaughter and retired to the human world to open a little milk tea shop. Yet reckless orthodox cultivators keep showing up to challenge him, the campus belle from the cultivation academy next door comes every day to buy taro balls and boba, and even the delivery app keeps recommending ads for "Crash Courses in Reviving the Demonic Path." Somehow, the retired Demon Lord's ordinary days are even livelier than when he was slaughtering his way through the Three Realms.
