The Heaven Shaking Divine Justice Shield was a Dharmic treasure fit for Spirit Immortals within the Divine Sovereign Justice Sect. As its level increased, its power would also increase exponentially. Once one could refine it to the eighth level, whether it be the protection it provided to its user or the 40% reflection when hit with an opponents' divine power and spells, they all made this treasure shocking even within the Divine Eye civilization.
However, it might be easy to refine the Heaven Shaking Divine Justice Shield at first, but refining it to its perfected stage was way too difficult. Even among the artifact refinement masters within the Divine Sovereign Justice Sect, there were less than ten of them who could refine this treasure to its eighth level!
