Tomb Raiding: I'm a Decent Person

(OOC, slow-burn romance, lots of original plot, all pairings are fair game, but there are no official couples in the main story, only hints of romance. The author tried hard to change the title but couldn't, so please go by the synopsis.) Sui An, the senior disciple of Shangqing Sect, is actually ambushed by a brat. She misses a step, falls off a cliff, and transmigrates to another world. She'd be embarrassed to tell anyone how it happened. Fortunately, she still has all the things she brought with her. And thanks to the nature of this world, she joins 749 as a staff member. She just never expected this world to have so many problems! Each time she transmigrates to the past, she saves someone and discovers more about herself. But can someone tell me how many more times I'll have to do this?! What secrets are hidden in the White Tiger Secret Realm, the Azure Dragon Secret Realm, the Vermilion Bird Secret Realm, and the Black Tortoise Secret Realm? When Sui An finally makes it back, she stalks up to Wu Xie's house and calls out, “Open up! 749 inspection!” Don't mind her. She spent so much money saving them all! She's got to earn it back! Wu Xie, who has been forced to lose his memory n times: “An'an, I signed the contract! So...” Hei Xiazi: “No way! As the old saying goes, An'an, you saved my life. Why not let me repay you by giving myself to you?” Xie Yuchen sneers and holds up a black card. “With you?” Li Cu looks at Hei Xiazi, then at Xie Yuchen. He can't compete with Hei Xiazi's physique or Xie Yuchen's money, but at least he's young! Zhang Qiling says nothing. He grabs the bewildered Sui An and runs.
