Mysterious tombs appeared all over the world one day, each containing a relic which grants its owner supernatural abilities. Joo-Heon Suh is a tomb explorer, excavator, and raider. Betrayed by his employer, he's about to die at the hands of a powerful new relic when he suddenly finds himself 15 years in the past, before any relics or tombs made their debut.
