After transmigrating into the body of an ordinary high school student in Jiangcheng, Xiao Feng awakens the [Dao Heart System], only to discover that his seemingly ordinary parents are extraordinary guardians who have retired from the world, while his adorably absent-minded younger sister is the reincarnation of the Violet Firmament Female Emperor.
Martial arts lie hidden in the bustle of everyday life, and gods and demons lurk beneath the neon lights. From choosing to stand up for justice against school bullies, to resisting workplace temptations and staying true to himself, to refusing to compromise when betrayed by his family, Xiao Feng rises step by step through trials in the city, guided by his Dao Heart: “Power is meant to protect, not plunder.” The System does not grant him mindless, overwhelming power. He can only exchange righteous insights for opportunities, and any damage to his Dao Heart makes his strength regress, forcing him to hold fast to his original convictions amid both violence and tenderness.
When foreign races begin coveting the Female Emperor's reincarnation mark, ancient clans bare their fangs, and a Deathless Demon God tears through the barriers between planes, Xiao Feng's retired parents can no longer keep a low profile, and his younger sister awakens the might of an emperor. Forced to shoulder the duty of protecting them, Xiao Feng journeys from Jiangcheng's underground martial arts black market to the reincarnation altar in the Kunlun secret realm, and from the mortal world of Earth to a contest spanning the cosmos. He stands shoulder to shoulder with his sister, using his Dao Heart to break free of fate and his mortal body to fight the Demon God.
