Lin Yuanshan, a lantern maker in Qingzhou City, awakened the firefly girl Aying in an ancient ancestral lantern, but was involved in a life-and-death situation that spanned three hundred years.
The new county magistrate uses all the children in the city as bait, hoping to refine the Yingling clan into an "eternal life candle"; the blood oath in the ancient lantern illusion, the counterattack curse deep in the underground palace, the soul-eating spider left behind by the Qintian Prison...
When the lantern skeleton hides its sharp edge and the tung oil burns out and turns into a galaxy, Lin Yuanshan and Aying use their ingenuity as their swords and soul fire as their guide to set up a thousand-lantern killing trap at the Lantern Festival.
This lamp illuminates the ghosts of people's hearts and guards the smoke of thousands of households.
