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

After taking the materials from the magic workshop, I transferred the prototype weapons, and the magic cannons on the outer wall, to my capital city.

I put them somewhere in the castle that no one enters, so I'm sure it wouldn't cause any problems.

I also brought along the documents as well.

With this, I had all the information I needed, and also obtained new methods to strengthen the Demon Lord's army.

Next, I transferred to the castle that towered over the center of the Imperial capital.

There, I killed the emperor and the nobles of the pro-war faction.

I knew their faces and names from the information we’d gathered previously.

Although I met with some resistance, it was within expectations.

None of the people who fought back were capable enough to be called a hero.
