Once the enemy acquires a considerable amount of soul energy, they can endlessly recruit more and increasingly powerful soldiers.
Meanwhile, as the soul energy in the Ghoul Territory becomes scarcer, the speed of summoning ghouls will slow, their quality will worsen, and the territory will fall faster.
Forget about this method of extracting soul energy; even a method of occupying speed is beyond the reach of ordinary people.
These advanced undead lords must synchronize soul pools one at a time for conversion. Only by sieging a core soul pool that has been synchronized for countless years, like the siege of the Corpses Domain, can a territory be captured in one move—the core soul pool of the Ghoul King is the Court of the Lost Souls.
The King of the Jackalweres resides in Yenogu's Siege.
Moreover, synchronizing and converting soul pools takes time.
Lands with similar nature to one's own convert the fastest, and vice versa.
