Seal of the illusionary realm Part 1

In the sword spirit world, demonic beasts were generally divided into nine grades. Grade one to three were low grade demonic beasts, and their combat strength was equivalent to ordinary cultivators who refined Qi into essence. Grade four and grade five demonic beasts were equivalent to cultivators who refined Qi and returned to spirit, and were already very difficult to deal with. Grade six to grade seven were equivalent to experts at the Return To Void stage spirit refining realm, and these two grades of demonic beasts were extremely powerful, much stronger than human experts at the Return To Void stage spirit refining realm. They were generally equivalent to human void refinement realm and Dao integration realm cultivators and were considered the top existences in the sword spirit world.
