Demon Realm, completely opposed to the Immortals and Buddhas, is not just a matter of simple interests, but more importantly a huge difference in ideologies.
Furthermore, during the ancient times, the Demon Ancestor Luohou suppressed the Primordial world. At that time, Hongjun Ancestor, who had not yet attained saintliness, along with Ancestor Yangmei, Universe Ancestor, and others, exerted the strength of nine oxen and two tigers to finally slay Demon Ancestor Luohou.
Later, Hongjun Ancestor, with half of the Jade Disk of Creation, comprehended the way of creation, attained saintliness, and established the Taoist Sect.
As for the defeated Demon Clan under Demon Ancestor Luohou, they all retreated into the Demon Realm.
Since then, the situation between the Demon Realm and the Immortals and Buddhas had become a fight to the death.
