Tomb Raider: I'm the Dragon Vein Janitor

Cheng Feng wakes up from a drunken stupor in a world where ancient tombs pulse with dark power—and he's been given the strangest job imaginable: cleaning up undead tomb lords. Armed with a system, the Shennong bloodline, and the Serpent God's blessing, he's now the ultimate "Purifier," tasked with wiping out vengeful kings and their monstrous guardians before they can rise and wreak havoc. From dragon veins corrupted by malevolent energy to fierce beasts guarding cursed relics, no tomb is too dangerous for this unlikely janitor. Time to sweep the underworld clean—one tomb lord at a time.
