Shen Lang glanced at him and said, "Blood Evil Island has a very secret technique called 'Feeding the Evil with One's Body.' Have you heard of it? Do you know the origin of Blood Evil Island?"
"No, I haven't... Does that mean using one's own body to feed Evil Qi?" Nanfeng Yao asked, a look of confusion on his face.
Shen Lang nodded. "That's more or less it."
"Blood Evil Island is called Blood Evil Island because, according to legend, a small fissure deep beneath it connects to the Nine Netherworld Prison. The Qi of Seven Evils from the Nine Netherworld Prison seeps out through this tiny crack."
"The Qi of Seven Evils is born from the negative emotions and pessimistic energies of countless beings in the Human Realm. When the Ancient Demon Gods were sealed in the Nine Netherworld Prison, their overwhelming resentment allowed this Qi of Seven Evils to spread and grow, eventually filling the entire Nine Netherworld Prison."
