On the southern frontier, the cold wind cuts like a knife.
Yu Nian'an tends his grandmother's shabby wonton stall. Their life is poor but warm, until a bully's club smashes the stove and scalding broth burns his grandmother's hunched back.
Consumed by rage, the boy feels a sinister blood-red maple mark on his forehead suddenly awaken! As he tears the bully apart, he hears demonic whispers in his mind.
An even greater storm soon follows. Officials collude with bandits, and a rain of arrows pours down! The white-haired grandmother who always called him "you little devil" and hid her last sugar cake for him swallows a mysterious pill. Her white hair turns black, her muscles knot like a Shura's, and she uses her own body as a shield, staining the long street with blood!
His last glimpse of her is her standing firm, riddled with arrows but with not a single broken bone.
Keep walking. Don't look back. Grandma doesn't hurt.
Immortals appear, and the road ahead opens. Carrying the sugar cake his grandmother baked and bearing the blood feud and the last wishes of his beloved family, Yu Nian'an sets out on an immortal path to slay the heavens, paved with mountains of corpses and rivers of blood.
Qi Refining, Foundation Establishment, Golden Core... all the way to the legendary Emperor Realm! He will turn the future around and save the past! He will make the scalding wonton pot boil again, and make his grandmother's white hair once more scold him beneath the maple tree:
You little devil, you put in too much salt again!
