The Kingdom Defending Jade Seal was a special treasure that was classified as a soul weapon.
A weapon that could only be controlled by an Essence Soul!
With it, he could shrink the Yu Nation's Void World territory to inches and mobilize the Yu Nation's fate to protect himself. He could also take a wisp of the nation's mental will and kill his target through the jade seal.
This target could be someone from an enemy nation, or a monster from the Void World. The only exception was it could not be a citizen of the Yu Nation.
For this reason, the stronger the dynasty, the more citizens there were, the stronger the strength of the Kingdom Defending Martial Sage.
When the Kingdom Defending Martial Sage became powerful, he could not only stop the monsters in the Void World, but also suppress the criminal organizations and evil forces in the country.
