In the year 2025, mysterious structures known as the Tombs of the Gods suddenly appear all over the world. Inside these tombs are ancient relics that grant supernatural abilities to those who can claim them, from the power of legendary heroes to the authority of mythological gods. The few who are lucky and fast enough to acquire these relics rise to establish powerful global monopolies, reshaping the world order under their control. Others have no choice but to serve them as raiders, risking their lives to loot tombs in the hope of scraps.

Seo Joo-Heon is one such raider, working under the corrupt employer Kwon Tae-Joon, who holds a monopoly over powerful healing relics. Joo-Heon is exceptionally talented, but when his skills begin to threaten his boss, he is betrayed and left for dead inside a tomb. As he dies, he swears revenge. A mysterious crow relic, carrying the spirit of a god, hears his oath and finds it interesting enough to send him back fifteen years into the past, just before the Great Catastrophe that brought the tombs to the world.

Armed with a decade and a half of painful experience and complete knowledge of future events, Joo-Heon awakens in his younger body with a single, ruthless goal: to become the Tomb Raider King. He sets out to steal every significant relic before anyone else can, operating on the principle that what is yours is mine, and what is mine is obviously mine. His primary targets are the powerful relics that Kwon Tae-Joon used to build his empire in the original timeline, as well as those that will fall into the hands of rival international excavation teams from America, Japan, and China. The relics themselves are not simple tools; they are sentient, often malevolent, and actively resentful of humans. Wielding them requires either building a bond through synergy or forcibly dominating them through sheer will, a process that takes a physical toll. Joo-Heon’s future knowledge gives him the edge to outsmart not only his human enemies but also the cunning traps and curses of the tombs.

As Joo-Heon travels the world, he accumulates powerful allies, including Irene Holton, a woman from a wealthy American family whom he frees from a cursed relic, and other skilled raiders whose memories of the original timeline are restored through his actions. His journey forces him to navigate complex geopolitics, dismantle powerful monopolies, and raid the seven great tombs, each themed after the seven deadly sins and guarded by relics tied to historical and mythical figures like Nero, Cleopatra, and Loki. His ultimate confrontation looms with Kwon Tae-Joon, the man who killed him, but Joo-Heon’s quest for revenge constantly raises the question of what will happen once he has seized all the power in the world for himself.
