Hei Ye, Your Compass Has Spikes

The heroine, Xie Yuci, is Xie Yuchen's younger sister, five years his junior. Born with the ability to sense ley lines, she can feel the flow of energy in ancient tombs like a living compass, pinpointing entrances, mechanisms, and even the location of "living things" such as blood corpses and corpse beetles. Within the Nine Gates, she's quietly known as a "walking map." To protect her, Xie Yuchen had her run a teahouse in Hangzhou from a young age, keeping her away from the tomb-raiding world. But a conspiracy targeting the Iron Triangle unexpectedly draws her into Wu Xie's adventures. Gentle on the outside but tough within, she's initially terrified of ancient tombs. Yet, as she faces danger alongside the Iron Triangle and Hei Xiazi, she gradually accepts her identity as a "compass" and falls for Hei Xiazi, who is always teasing her. The hero, Hei Xiazi, retains his original traits: poor eyesight, a carefree attitude, and uncanny combat skills. At Xie Yuchen's request, he agrees to "look after" Xie Yuci. But after one tomb adventure after another, his perfunctory attitude turns into an instinct to protect her. He even shows his favoritism openly in front of the Iron Triangle, becoming the team's resident protector of Yuci. The story begins when Wu Xie first descends into the Seven-Star Lu Palace. Xie Yuci unexpectedly enters the scene, and her "living compass" ability saves the Iron Triangle from danger time and again. She and Hei Xiazi go from mutual dislike to standing by each other through life and death. In the end, she becomes the Iron Triangle's most steadfast ally, and together they face adventures in Xisha, the Qinling Mountains, the Cloud-Topped Palace, and elsewhere. Amid the darkness of ancient tombs and the light of human nature, they piece together a bond that belongs to them alone. Any details that differ from the original are my own additions. Thank you.
