The Heart of the Supreme Evil Spirit

Like the Dragons who had left the Nine Realms for the Dragon Realm and cut off all contact with the Nine Realms, the great monsters who had transformed with spiritual intelligence couldn't coexist in peace with the human beings in the Nine Realms, either. As a result, they had all stayed in the Realm of Evil Spirits.

But there was a difference between the Dragons and the great monsters. The Dragons were too proud to live with the human beings in the Nine Realms, so they had moved to the Dragon Realm.

The evil kin had wanted to live in the Nine Realms. They had even intended to replace human beings to dominate the Nine Realms, but their wild ambition had been found out, and some strong men had driven them away into the Realm of Evil Spirits.

They had also forbidden the transformed evil kin from entering the Nine Realms. If they did, they would pay a big price, which was the Restriction for Evil Spirits.
