Under the bloody full moon, fifteen-year-old Ding Ping picked up a pair of twin cubs - the black wolf Ding Qing and the white wolf Ding Hao - from the wolf den. The blacksmith's chain and the herbalist's mint have created two completely different fates for the two wolves: the black wolf imprisoned by the iron spike collar breeds dark fire in the brutal training, while the white wolf tied with a silver bell awakens his psychic power during the children's play. When the black wolf was expelled for protecting his master, and the white wolf was appointed to guard the spiritual beast that night, the growth rings of Maple Town had quietly carved a bloody prophecy.
Twenty years have passed, and the weak black wolf of the past has become the wolf king who rules the mountains and forests, leading a pack of wolves equipped with fire and tactics to make a comeback. The burning windmill collapsed, and the white wolf used his body to build the last line of defense in front of the church. The emerald light bursting out of the collar reflected the white frost on Ding Ping's temples. When the surviving one-eyed old man took the mechanical wolf to the top of the snow-capped mountains, the mother wolf's mournful cry when she was orphaned fifty years ago was finally transformed into the eternal embrace of the twin wolf souls in the ice avalanche.
This fateful showdown spanning half a century came to an end in an avalanche caused by a baby's cry, but left a deeper question: Which one, chain or mint, is the key to the beast's heart? On the wrists of the newborn baby with strange eyes in the ruins, the silver bell and the iron chain are resonating with the pulse, and the machine wolf sleeping deep in the ice lake contains secrets that can subvert the next hundred years...
