The warm canals of the Beast Plain run dry, and the fire seed well is locked dead by cold cores. Blacksmith Niu Tieguo is publicly taken down by patrol rabbit Tu Banya, and the black pot becomes the criminal evidence. Warm accountant Shu Suanpan steals the fire seed to save the rat clan, but is instead utilized by the Frost Shadow Caravan, altering accounts to frame others. The three fight from the arena to the fire seed well, then chase toward the earth vein gate. Seven cold cores, one ice gate, the frost ledger lord secretly manipulates the abacus. Niu Tieguo blocks the cold with a pot, Tu Banya's dual blades cut pearls, Shu Suanpan calculates the path to redeem his mistake. The fire seed is about to extinguish, and the Beast Plain enters winter. Traveling together, can this account be settled clearly?
