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

That afternoon, I visited the Previous Demon Lord’s Territory.

There was an endlessly large lake in the vast wasteland.

It was something I had created with magic.

There were two large ships floating on the lake.

The ships were anchored as they were lined up at a certain distance.

In between the two ships, there were soldiers of various races fighting each other.

Although it looked like a pretty fierce battle, it wasn’t a real war.

It was a training session that had assumed the face of a battle at sea.

In recent years, nations from outside the continent have frequently interfered from across the sea.
