Guding had reached his limit in the contest of momentum, while his opponent clearly still had reserve strength. This was the second time Guding had encountered someone with greater strength than his own at the same level of cultivation.
The first was Boi, who had emerged from the Purgatory Gate. Of course, Boi couldn't really be considered to have the same level of cultivation as Guding since he used to be a True God.
The second was the man before him now, named Angold. Guding didn't know that Angold's true strength was something even three Order Commanders dreaded encountering.
