Taking Dens Is Impossible!

If the strength of the zombies matched the strength of the original monsters, then I wouldn't have to worry. However the zombies got boosted and their strength scale was modified to match the difficulty of this quest.

Dealing with them was going to be a headache. And I couldn't tell if the angels would keep pushing their defensive shitty weapons to protect these zombies or not.

Also I didn't know if the dens would play a role in helping these zombies. If so, then I wouldn't succeed with my current power and armies.

Throwing armies like ditching away dirt wasn't going to work. My armies were helpless against the grand zombies, and the losses I'd suffer would backfire at me as more strong zombies would emerge.

Honestly speaking, this quest started to be a nightmare for someone like me. What should I do then?

To be honest, I only had limited options in front of me. Either I should deal with this problem from the root, or either I ignore it completely.
