In both The Lost Tomb and Fatal Journey, we are focused on a main protagonist who's strongest contribution is their intellect and knowledge, supported by family and friends who help with the fighting aspects of their missions..
In both productions, there is a certain degree of supernatural/undead contribution to the conflict, as well as human complications. Plus, they both possess similar tones/moods, as well as primarily taking place in a tomb, composed of various traps and puzzles that must be solved to proceed safely (thus our MC's strengths are played to their full potential).
They also both belong to larger fantasy and bromance franchises:
Fatal Journey (although it could be watched independently in theory, if one does not mind spoiling the main franchise), is a branch-off story focusing on a side character from The Untamed - a Xianxia bromance adapted from a danmei novel. Meanwhile The Lost Tomb is the first installment series to the titular franchise - a modern fantasy (with cultivation elements) bromance story adapted from a novel series.
