The demons are creatures that feed on human chakra. There are also Minions, which are an inferior version of Demons. There are a total of 10 levels of Minions.
Level one Minions have the same strength as ordinary humans. They can be defeated by an ordinary human with ordinary weapons.
Level two Minions have the same strength as a 1st layer Prana Gathering practitioner and can be defeated with ordinary weapons.
Level three to level eight Minions have the same strength as 2nd to 7th layer Prana Gathering practitioners, respectively.
Level nine and level ten Minions have slightly higher strength than 8th and 9th layer Prana Gathering practitioners, respectively. They can only be killed with root-level spiritual weapons, as these levels of Minions undergo body refinement once they reach level nine.
