The Five Devils in his inner world gathered despair, fear, bloodlust, greed, and resentment into one entity. In the land of the hollow spirits, they had swallowed a lot of hollow spirits, and then laid dormant. They had no response, as they seemed to head towards an evolution, changing slowly.
Shi Yan had almost forgotten that he had these Five Devils hiding in his Sea of Consciousness. As they were flying above the Dead Soul Mountain range, he didn’t know what sort of energy provoked them, making them scream inside his Sea of Consciousness. Soon, they would wake up the thought of which frightened Shi Yan. He couldn’t help but sink into his mind to carefully check the status of the Five Devils.
In his Sea of Consciousness, the Five Devils were like five groups of dusky smoke where he couldn’t see the despair, fear, bloodthirsty, greed, and resentment hovering clearly. Usually, just a small stir up was enough to provoke these negative feelings.
