Well-Written The Grave Robbers' Chronicles Fan Fiction

Looking for books similar to *Tomb Raider: I Demolished the Golmud Sanatorium*. Original characters are fine, and Ping-Xie or Hei-Hua pairings are welcome. The characters need to be smart. If there’s an original character, I’d prefer no CP. No everyone-loves-the-protagonist setup!!! No CP, no everyone-loves-the-protagonist setup! “Ice in the poison.”
