Above that was the bronze corpse. Not only did it have a Bright Aperture Stage cultivation, but its entire body was as hard as black iron. Ordinary weapons couldn't injure it at all!
There were also silver corpses, golden corpses, and the flying yakshas and indestructible bones that the Corpse Sect relied on to deter the East Sea Path!
However, once they reached the Silver Corpse level, only cultivator masters could refine them.
The corpse puppets controlled by the three Corpse Sect disciples were only bronze corpses.
But even so, they were elites carefully selected from the bronze corpses. From the looks of it, their strength was equivalent to an ordinary ninth-level Bright Aperture Stage cultivator.
The six bronze corpses alone suppressed the three disciples of the Flying Cloud Sect.
