Wang Yu's Corpse Puppet Dao Pattern can control cultivators whose cultivation is higher than his by a small realm at most.
Wang Yu is currently in the Early-Stage Foundation Establishment, so he can at most control up to Mid-Stage Foundation Establishment. The number of corpse puppets he can control now is three.
However, the Dao Pattern is within his Spirit Flower, so he naturally senses it and knows that as he breaks through major realms, the number of corpse puppets he can control will continuously increase.
In short, the way for Wang Yu to enhance his combat power now is simple: Find three Early-Stage or Mid-Stage Foundation Establishment cultivators and, at the moment they newly die, when their spiritual mechanism has not dissipated, convert them into his corpse puppets.
To catch them just after death, where would you find such coincidences, except to make them yourself.
In other words, personally kill Foundation Establishment Feather Scholars to create corpse puppets.
