From the Start, I’m the Prison Warden: Burn Incense to Summon the Invincible Immortal Emperor

[Eastern Fantasy] + [Invincible] + [From the Start] + [Face-Slapping] + [Summoning] + [Behind-the-Scenes] + [Feel-Good Power Fantasy] Everyone knows of the ten Grotto-Heavens. The eleventh is one history dares not record and Heaven dares not destroy. Xie Wujia has sat inside it for ten thousand years, watching nine people: a tyrant from the previous dynasty, a river-splitting Sword Demon, the Emperor of Ten Thousand Demons, a mad ancient Buddha... Today, the noble families of the mortal world refine pills using ordinary people, while sects slaughter villages to harvest blood. One day, a young man from a fishing village burns a stick of incense. Its smoke drifts into the prison. Xie Wujia knocks on the cell door. "We've got work. One stick of incense. Who's going?" The nine fiends, their names erased from the history books, rush to the cell door at once. Later, a pardon list appears in the skies above the Nine Provinces., Later still, the True Lords and Heavenly Venerables of the age line up to beg him to imprison them.
