Eight hundred years ago, the Three Realms signed the Pact of the Calamity Lantern: once every sixty years, one person would be chosen as a lantern to absorb all the world's foul energy, then sacrifice themselves when the heavenly tribulation arrived.
Jin Ming was the nine hundred and ninety-ninth Calamity Lantern, and the only fool willing to enter the Demon-Suppressing Abyss.
When he discovered that his life-lantern contained his master's refined soul, and that three thousand bronze lanterns beyond the Ninth Heaven were all fueled by his blood and bones, he finally crushed his natal lantern and released the primordial calamity spirit imprisoned for ten thousand years.
“If all living beings want me to be their lantern, then I'll burn this body to ashes and illuminate the absurd tribulation that has befallen the Three Realms.”
