The fallen are not truly fallen; they are the Dao's forbidden scales.
Du Wenzhi was born with every meridian sealed, a good-for-nothing outside the sect of Heaven's Mandate. One bowl of porridge handed out on a snowy night draws him into the sect's deepest secret: a Reincarnation Well whose existence is never revealed to outsiders, and a blood feud spanning countless lifetimes. Gradually, he comes to understand that those who fall from the Dao are not abandoned by the Heavenly Dao. They are wounds it inflicts on itself as it tries to heal.
After the sect is destroyed, an even greater game begins. The He Dao Alliance is riven by infighting, the one pulling the strings cannot let go of their obsession, and the true force behind it all is an ancient beast lurking behind the seven obsessions of all living beings: the Seven Deadly Sins. He chooses to merge completely with his fallen Dao persona, determined to forge a third path that no one has ever managed to walk.
