The Buddha Realm, although not as powerful as the Immortal World, has reluctantly reached the threshold of the Supreme World with the support of two Saints and massive Willpower.
Apart from the Buddha Realm, the Twelve Ancestral Witches of the Witch Clan also chose to unite to form the Witch World. This world is stronger than the Buddha Realm, and it is also a Supreme World.
In the old times, although Buddhism Dao was a significant force second only to Immortal Dao, those who knew were aware that Buddhism Dao was only loud in name; in terms of true strength, it didn't even rank in the top three of the Prehistoric World.
The strongest force in the Prehistoric World was undoubtedly Immortal Dao. And the force second to Immortal Dao was never Buddhism Dao. Before the Ancient Time, it was the Primordial three tribes; during the Ancient Time, it was the Demon Clan and Witch Clan; after the Ancient Time, it was the Human Race.
