A piece of charcoal fell from Taishang Laojun's alchemy furnace, tearing apart the hypocritical peace of the three realms - fire from the sky entered the belly, ice crystals were locked, the blood of the demon clan boiled, and the red boy was an alien that could not be tolerated in the world since he was born. He has the ice-patterned birthmark of his mother, Princess Iron Fan, branded on his chest, and the real fire that burns mountains and seas boils inside him, but he is willing to use this power to roast sweet potatoes, warm the stove, and form a "volcanic ash trio" with salamanders and tangerines to turn scorched earth into fertile land. However, deep in the cracks in the ground, the fireworms he fed every day were quietly evolving into giant lava beasts. Every time the insect plague was suppressed, a strand of white hair from the iron fan turned into sealed ice threads, burning out her life inch by inch... When the giant beast tore the earth apart, the iron fan fell into the cracks at the cost of the soul, when the ignorant people regarded Red Boy as a disaster star, and when Xiao Tangcai was pierced by the poisonous arrow in the chest, the young man who once swore that "fire does not hurt anyone" was completely furious. He tore up the ice-patterned birthmark, burned the lava through the mountains and forests, and rushed to the thirty-third heaven on the fire of karma: "You said fire bugs are evil? In the alchemy furnace of loyalty and filial piety in heaven, what is refined is the sin of eating people!" This is a confrontation between ashes and gold bricks, and a sweet potato nursery rhyme's rebellion against the shackles of loyalty and filial piety. Red Boy drives a plow made of volcanic ash and plants a ladder of wheat ears on the scorched earth that reaches into the sky. When the alchemy furnace was recast as a stove for ten thousand monsters, and when the broken horn of the Bull Demon King turned into a plowshare that shattered the sky, the young man sneered at the collapsed Taishang Laojun: "The fire from heaven cannot burn away the ashes, but from the ashes - a new human world grows."
