Tomb Raiding: I Came from the Bronze Gate

[No heroine + a protagonist who seems sweet but is secretly ruthless] Wu Yu has always been fascinated by the Notebook of Pits in the Three Thousand Worlds. He sets out to find its parallel worlds and experience them for himself. System: Master, don't worry. I'll arrange everything perfectly for you. Wu Yu comes with the bloodline of a Heavenly Dragon. He makes himself a black-gold ancient saber just like Brother Xiao's, and teaches himself all kinds of combat techniques... He becomes Wu Erbai's adopted son, with a tragic backstory that makes him seem delicate and frail, though he's actually strong. He gets to experience tomb raiding firsthand... Ding! Reward unlocked: underwear you never have to replace. Even with Wu Yu's impressive skills, he still can't escape his brother Wu Xie's passive skill: bad luck. At the Golmud sanatorium, he “happens” to run into Wu Xie and saves him from trouble before Brother Xiao can. Under Wu Xie's astonished gaze, the two set off for Tamutuo together. He saves Pangzi in the Snake Marsh Ghost City and studies the venom of crested snakes. He enters the meteorite jade and saves Brother Xiao. He clings to Xie Yuhua's coattails. At Banais, Wu Erbai discovers that he's dropped his act... As one mystery after another is solved, it begins to set a series of events in motion. Can problems that have persisted for hundreds, even thousands, of years finally be resolved?
