Tomb Raider King, Vol. 2 (manga)

Jooheon’s next destination is the fabulous city of Las Vegas, where he expects powerful Relics to appear at the secret auction, maybe even a Deity-class if he’s lucky. To get his hands on the prize, he must compete with other wealthy bidders, including his archenemy, Chairman Kwon. The ante is upped even further when a terrifying presence enters the fray. With all bets off the table, Jooheon must rely on his skills and wit to even the odds!
