The Executed Sage Reincarnates as a Lich and Begins a War of Aggression

I went to a remote region of the territory.

There were burnt objects scattered around, as if to cover the bare ground.

Those objects were cylindrical and about the size of human beings; both ends of their body was thin, as if they'd been squeezed.

Feather-like objects grew uniformly on those strange objects.

Apparently, they were the burnt corpses of mysterious creatures.

The number of those objects sprawled on the ground was no less than one hundred thousand.

And from those corpses, the remnants of miasma could be felt.

It seemed that they were the beasts of the other world.

So they’ve already been defeated.
