Let you simulate life, but you change fate every time?!

"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.
