The Talisman Master of Tomb Raiding

For some unknown reason, Bai Fengyin accidentally transmigrated into a tomb-raiding world and lost some of her memories. Somehow, she knew she had to find a jade pendant carved with a black peony, so she began frantically raiding tombs.

When she first realized she had transmigrated into the world of The Grave Robbers' Chronicles, Bai Fengyin had no desire to get involved with the main cast. But even though she deliberately avoided them, she still met them and formed deep bonds with them...

Content warnings: multiple male leads, all pairings; the protagonist is wildly impulsive and doesn't care about her own life. Enter at your own risk. Sweet story, no angst. (I'm no good at writing a synopsis, so please check out the story itself.)
