The Daoist Geng Kun and his brother, Daoist Geng Peng, both hybrids of human and demon, situated between man and beast, usually didn't take human disciples but rather sought half-human, half-demon creatures to mentor, planning to establish a unique sect.
The problem was that hybrids usually had poor spiritual roots, and even the humans were mostly mediocre, many showing selfishness, greed, and cruelty. Since ancient times, few could truly cultivate the Immortal Path.
Demons were even worse, often possessed by anger and ignorance, bloodthirsty and cruel. Once they mastered spells, they frequently went on killing sprees, causing endless disasters. Many merfolk, otterfolk, and frogmen used spells to kill indiscriminately in the ocean, enjoying the thrill of slaughter like cats hunting mice.
