All the Spirit Ritualists issued psychic commands, putting all the Foukth Demons into a sleep state. This is because when these Foukth Demons are awake, they only think of killing, and the spirit ritualists have to suppress them, which is very consuming of spiritual power.
Lanling's spiritual power invaded the brain domain of the Foukth Demons and began to search for the area where the Foukth Demons signed their mental contract.
This area is where the Spirit Ritualist left a psychic imprint when the Foukth Demons were very young. It is this area that accepts the rituals' mental commands.
Lanling's spiritual power traveled within the brain domain of the Foukth Demons.
Fortunately, the Foukth Demon is a cruel yet simple species, so its brain domain is relatively simple and not large.
But even so, it is still a boundless mental world.
Lanling's spiritual power continued to search, search, search...
Four hours, ten hours, fourteen hours…
A full eighteen hours!
