"The enslavement effect of the [Undead Calamity] is still so useful."
Lu Yuan chuckled lightly.
In his perception,
All the dozens of scouts and informants from Black Stone City had been transformed into Catastrophe Servants.
In the Main World, many methods exist to enslave subordinates.
Such as bloodline restrictions, soul contracts, and so on.
But the most terrifying aspect of the [Undead Calamity] is that
it can keep everything unchanged after transforming enemies into Catastrophe Servants.
Even their closest friends wouldn't notice anything unusual.
It can silently infiltrate enemy ranks and penetrate them thoroughly!
This is also why Lu Yuan is wary of Undead Amon and unwilling to expose himself too soon.
Otherwise, with his current soul strength, he could control and enslave the entire Laine Kingdom in an instant!
But Lu Yuan knows very well.
Papers can't wrap fire.
