In a silent apocalypse, sound is a deadly taboo. Monsters roam rampant, and humanity hides underground, barely clinging to life. Su Xiang transmigrates into this soundless apocalypse and awakens a Chinese New Year-themed system. Using firecrackers and other festive New Year items, he slays monsters and joins forces with Lin Qingleng and Nezha, a mechanical boy, to head for Central City. Along the way, they overcome all kinds of bizarre crises. Eventually, they expose the dark conspiracy of Central City's ruling elite, overthrow their regime, slay the ultimate Demon Emperor, and restore vitality to the world.
