Restraint was restraint, but it merely restrained.
Its battle capability was not very strong, almost nonexistent, purely an auxiliary ability.

It was simply terrifying.
Arguably the longest-living King Gu.
Of course, this also meant that Da Yan had maintained justice in the hearts of the people for at least thirty thousand years.
As long as the Da Yan Dynasty had not lost the people's hearts, it would not perish.

Even if Emperor Earth lost his Fatian Xiangdi, Xiezhi still was not a match for Emperor Earth.
Just with the Undying Decree's bestowed Undead, it was enough to utterly trample Xiezhi's host.
