The so-called Spirit Tribe divine blood was something that he was very interested in.
This blood was a type of mysterious liquid that would be produced by the soul of a Holy Spirit level Spirit Tribe cultivator following death by natural causes.
If the blood were to be dripped onto any sentient object, the latter would develop intelligence and evolve to become a low-grade spirit.
Of course, the Spirit Tribe wasn't entirely created by such a method; most of them evolved on their own to become low-level spirits.
However, this divine blood was still an extremely important tool for the Spirit Tribe in their quest to maintain their population. As such, it was something that they guarded as secret treasures.
