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

An artillery shell with an engraved spell?

I stared at the object flying toward me in a bid to identify it.

Designs had been made to stabilize its trajectory while accelerating the projectile in many places.

In addition, it is imbued with a powerful holy attribute.

It is quite the sophisticated weapon.

It seems that the empire is still in a state to be able to install several of these things.

There was no information about this from the spies.

It seems that the existence of these weapons was kept secret after all.

For my subordinates to not know of this, they must have been quite scrupulous in managing their information.
