After Saving the World, I Was Dragged Off to Work in a Tomb-Raiding World

I recently watched Jiumen and got completely hooked on Ji Xiaobing's Xie Jiaye. I wasn't all that interested in the plot set during the Jiumen era before, but now I want to be Xie Jiu's devoted fan... So I got an idea and decided to write for fun, hehe. I'll definitely be changing parts of the plot and timeline, and some OOC is inevitable. I'll also break up a few ships. I'm especially into 18/-8 and the like. There'll be secondary couples in this book too, classic pairings like Ping Xie and Hei Hua (after all, I'm writing fanfic, cut me some slack, QAQ). This is a top-focused story, with Xie Jiu as the bottom. There may be scenes where other characters have unrequited feelings for Xie Jiu. I'm a bit obsessed with Xie Jiu, so don't read if that's not your thing, and please don't curse at the author. The protagonist is incredibly powerful. The opening will tell some of his story (I haven't even dipped the dumplings in vinegar, but I keep wrapping more and more of them). But he'll be held back a little in the tomb-raiding world (otherwise I really wouldn't know what to write. With power like his, he'd wipe out all the villains in a few quick moves and the story could end right there).
