Tracker Hunter X: The Blood Trail Mystery

Lin Haoran holds a secret power that defies logic—one drop of willingly given blood lets him track anything the donor desperately seeks. But when his adoptive father vanishes without a trace, leaving only a cryptic letter and an impossible-to-open puzzle box, Lin's abilities are put to the ultimate test. The letter's instructions are clear: travel to Moon Mountain on his twentieth birthday and find a girl named Yue Kaixuan. What begins as a search for answers spirals into a journey through hidden conspiracies, supernatural mysteries, and a parallel world where nothing is as it seems.
