This is not the Cultivation World; those with abilities in this world of weak Spiritual Energy are merely beginners!
Perhaps some have transformed into demons, but those potions surely aren't as powerful as Eryao and Green Ox!
Eryao has told him that there's no scent of a great demon around this place!
There exists a Demon Association, all reported within certain organizations, holding identities!
Jiang Tang altered Eryao's and Green Ox's identities directly in King Yama's Book of Life and Death, injecting this information online!
They would then have ID cards or similar, registered within the entire security network!
As for whether they need these identities to buy houses, take buses, or stay somewhere?
With flying treasures, they don't need to take planes, buses, and all travel is conducted under Jiang Tang's original identity.
Jiang Tang's original identity is genuine; his company's and personal assets are under his name!
