Five hundred years ago, Sun Wukong wreaked havoc in the Heavenly Palace and kicked over the alchemy furnace. A furnace brick fell to the mortal world and turned into the eight-hundred-li Flame Mountain, causing the seal of the Earth Core Inferno Patriarch to loosen accordingly. On the journey for scriptures, the Flame Mountain blocked the way, and only Princess Iron Fan's plantain fan could extinguish the fire. Wukong went to borrow the fan, but was rejected due to Red Boy's old grudge. In the first attempt, he was fanned away eight hundred li; in the second attempt, he turned into an insect and entered the belly to cleverly obtain the fan, but was tricked back by Bull Demon King transforming into Bajie. In the third attempt, he engaged in a heaven-shattering and earth-shattering battle with Bull Demon King. Bajie, Nezha, and the heavenly soldiers and generals all came to help, and the pagoda suppressed the stone body of the Bull Demon King. Heavenly King Li exposed the truth about Red Boy, the Bull Demon King surrendered, Wukong fanned out the fire of Flame Mountain, and the master and disciples continued their journey west.
