Even though Gaven possesses the power of Undead Slaughter, which has a certain suppressive effect on these undead, he cannot occupy the Ghoul Soul Pools and make the corresponding ghouls his own soldiers.
Now he has returned to the original path and must physically eliminate them all, reverting them to a state of soul energy before Gaven can devour them bit by bit.
Moreover, many abilities that Gaven has, the Ghoul King also possesses, such as directly manipulating soul energy.
The plan he originally envisioned, with the Undead Slaughter Army advancing on one path and the underground soul energy channel on another, to quickly invade Ghoul Territory has failed.
The ghoul soul pools he occupied along the way were all empty shells without soul energy.
The only consolation is that it is now within the scope of a divine war.
