First and foremost, there is no doubt about the enhancement of authority. The two Authority Techniques practiced by Xiao Mu, One Stroke of Life and Death and Opening the Gates of the Underworld, have both gained significant improvements.
After using One Stroke of Life and Death, the persistent Power of Life and Death can condense into a shadow that suppresses the divine injury of the opponent, slowing their Escape Speed.
It can be said that after reaching this step, it has become much more difficult for Mutated Beings who have been hit by Xiao Mu's Authority of Life and Death to use their high Escape Speed to flee from death.
Secondly, it is the Opening the Gates of the Underworld. The Authority Technique of Opening the Gates of the Underworld has also improved. When Xiao Mu opens the Door of the Underworld, more invisible Bone Hands will extend from the Netherworld and drag the opponent into it.
