World setting: In a modern urban world, a secret order of “Tomb Guardians” exists. The protagonist isn’t a conventional tomb raider, but the last heir to a family of tomb guardians, tasked with stopping evil cultivators from looting tombs and sealing away the malevolent entities within. The story follows two parallel struggles: fighting tomb-raiding gangs motivated by money or power, and confronting the eerie beings awakening inside ancient tombs.
The central mystery: Thirty years ago, an archaeological team led by the protagonist’s father vanished in the “Dragon Abyss Tomb” in the Qinling Mountains. All they left behind was half a bloodstained letter and the words, “The dragon vein is alive.” As the protagonist investigates the truth, he discovers that every clue points to a shocking secret: China’s dragon vein is alive, and someone wants to “slay the dragon.”
