After my loss to Demon Lord Valefor, the [Domination] effect I had on the monsters was deactivated.
Upon my revival, I didn't even have enough power to defeat, let alone control them since I had to sacrifice my Levels to request the impossible from Death.
'Thank goodness the monsters were handled before they could flee in the direction of the settlement.'
My 'buddy', Death, helped me annihilate all of them—both the ones on Valefor's side, and the ones I had utilized—as a farewell present, solving the problem for me.
However, this left me with another problem I wanted to avoid in the first place.
'The Helios Labyrinth is as good as useless now. There are no monsters and also no valuable resources within.'
That meant the sooner or later, Dulum's economy would collapse, as their primary means of livelihood was gone.
