The Corpse Puppets possessed tremendous advantages, and because of it, high-ranking Corpse Cultivators like the Corpse Commanders rarely risked their true bodies on the battlefield.
Instead, they refined substitute corpse vessels before splitting a fragment of their undead soul and integrating it into those puppets.
After countless years of refinement, the split soul and puppet became one, allowing them to unleash nearly all of their combat strength while keeping their true corpse vessel and complete undead soul hidden safely away.
It was an almost flawless substitute technique. Yet that advantage carried an equally terrifying weakness: it was a taboo spell.
In truth, if the split undead soul were destroyed before returning to the original soul, the damage would become permanent, and unlike ordinary soul injuries, this wound wasn't merely spiritual.
