I would bet on the Dryad having a somewhat mediocre Domain for crowd control. After all, I doubt the Myriad Cauldron Sect would willingly/knowingly allow demons to be born in one of their subspaces, and the Dryad Queen is likely not a full demon yet and probably doesn't have a mystic art to guide her growth. As for examples of domains, all plant type beasts are enticed and invigorated into mindless soldiers (as long as they don't take took much damage or get too scared), or another domain might be for spiritual roots to spread around a set area and slowly consume corpses to heal herself/others.
I just realized: Xie Tian just met the possible conditions for learning [Nature's Heart] right now. He is surrounded by many monsters and will likely have to push himself to the limit to kill anyone in his way (without getting sneak attacked). At this rare, Xie Tian might become equal to or better than Cao Mao in melee combat. After all, [Nature's Heart] is the trope for all melee type MCs and all talented external martial artists, and with it, Xie Tian will become more efficient in general, reduce the burdens of environmental conditions, and can increase his attack power.......I can only hope that Cao Mao gets ambushed by a powerful beast or a big pack of reckless carnivores.
Also the spirit wooden corn is cool, should be helpful as an alchemist to have the wood element so something that can increase his power in it is cool, he just has to use the Rooster God blood enough times(I'm quite sure it increases resistance to wood). Also the spirit corn is cool too, if it is anything like spirit beverages it should be beneficial to Cultivation so having it as part of a meal should be good(plus he has a lot, more than enough for him to share it with his wife and concubines).
