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

I was on the roof of the castle.

I watched the Demon Lord's army being formed below me.

They were the ones who would participate in defeating the Hero this time.

Their total count was two thousand.

Most of them were undead.

The living demons made up only a very small number of the troops.

In order to avoid causing unnecessary damage, only an elite few had been granted consciousness.

Even though they had just awakened, their opponent was the Hero.

I will do my best to prevent my allies from getting killed, but I don't know how far I can protect them.
