I have a suggestion. If he want to build the Fairy Kingdom he needs more fairies but just robbing graves is not going to work. He'll need powerhouse under him and for that he need stronger resources and corpses and the major and minor organisation in that world are not going to leave it lying around, easily accessible. He can join the Holy Spirit Cult using his commandment power and kill them or when they die take their corpse to turn them into fairies. He can also gradually takeovers the Holy Spirit Cult and do what Qiangu Qingfeng did.
