Slayer of Gods: The Mysterious Nightwatchers tells the story of Lin Qiye, a transmigrator who awakens the power of the Ghost God Summoning as a Nightwatcher in a world that combines the settings of Lord of Mysteries and Slayer of Gods, and is drawn into conspiracies and battles that will determine the world's survival.
From his first steps as a Nightwatcher in the shadows of Tingen, where he encounters mysterious history and Forbidden Ruins reactions, to exposing the Celestial Worthy's conspiracy amid the mists of Backlund and experiencing his first Ghost God rampage; from entering the Forsaken Land to seek the ultimate truth and awaken the Slayer of Gods blade, to preparing for battle as the apocalypse begins and facing choices that will decide his fate, Lin Qiye's path is filled with danger and sacrifice, culminating in an epic showdown at the Gate of the End.
Along the way, he joins forces or clashes with Leonard, Klein, and others. He grows by merging Sequence abilities with Forbidden Ruins powers, while contending with threats from the Aurora Order, the Rose School, and other factions, and confronting the terrifying existence of Mr. Door and the Celestial Worthy. The dual endings give profound expression to themes of protection and sacrifice, reason and madness, portraying the Nightwatchers' faith and sense of duty as they persevere in the darkness, and the transmission of civilization's flame across time and space.
