An ancient tomb lies deep beneath the subway, a royal mausoleum is buried under a derelict building, and a forbidden zone beneath the sea connects to a stone gate leading to another world. Lu Xuan appears to be the heir to an antique shop, but in truth, he is the last successor of the tomb-guarding lineage. With an ancestral broken ring in hand, he can devour baleful energy, artifacts, souls, and formations. Others enter tombs for wealth; he enters to take lives. Others grab the treasures and leave; he refines entire tombs into his trump cards. Corpse formations, ancient coffins, broken swords, primordial blood, evil cults, alien races, and the secret treasures of dynasties all become fuel for his growth. As ancient martial arts return and passageways to the myriad heavens open, Lu Xuan fights his way through the cities and countless worlds, forging himself into the king of tombs, guardian of tombs and nation, and vanquisher of every foe.
