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

That day, I was relaxing in a room in the castle.

It was an entertainment room that was set up a while ago.

Diella and Henry were in the room as well.

The two were sitting across from each other at the table with a serious expression.

On the table, there were boards evenly divided by a number of squares.

White and black pieces were arranged irregularly, and the two moved them alternatively.

This was a game that reproduced war at a reduced size.

It was something made using things from John Doe’s memories, which was then independently improved by the executives.

As for the context, it was about the war between the Demon Lord’s Army and the human army.
