The Fourth Calamity: All My Players Are Cthulhu's Chosen

Chen Jin transmigrates to a high-magic medieval empire and becomes a disgraced count in exile. His domain is the infamous Blackstone Keep, a borderland suppressing an evil seal over an Old God. Just as a plague breaks out in the north and the empire grows weak, a neighboring duke lays siege to the keep, vowing to seize the evil god’s relics. At court, the hawks try to organize a resistance, but the appeasers have them all exiled under the pretext of the plague.

At this critical moment, Chen Jin binds the Old Ones’ Followers Summoning System. He disguises the world as a hardcore sandbox game called Blackstone Age: Cult Wars and summons players from Earth. These players don’t grind for resources or fight monsters to level up. They worship the Old Ones, relish blood sacrifices, and are utterly obsessed with the Cthulhu Mythos.
