Heart demons are also obsessions. If one cannot overcome them, one can only satisfy one's desires to clear the mind.
Among the corpses Jiang Yuebai saw that night, there were Qi Cultivation Disciples, Foundation Establishment Disciples, and even some Golden Core Masters, all definitely suppressed by Fang Ruyan using special methods, allowing Lu Nanzhi to kill them one by one.
Perhaps this was also one of Fang Ruyan's methods to make Lu Nanzhi cultivate killing intent and fall into demon cultivation. According to the books, true demons are born from the formless muddy qi of heaven and earth mixed with intense desires.
Humans practice demon cultivation mainly because they are eroded by heart demons, or they have special cultivation techniques and ways to enter the Demon Dao. Strictly speaking, the Ghost Clan can be considered a branch of the Demon Dao, but the Ghost Clan prefers to call themselves the Evil Dao.
