The all-terrain self-propelled artillery she commanded had been souped up. Upon entering operational status, over a hundred barrels began to spray wildly, as if they required no soul power at all, shattering the large expanse of soul guidance cannons arranged by the soul engineer corps around her.

Inside the self-propelled artillery, there were more than thirty level-5 baby bottles installed, enough to keep it in combat for several hours without needing replenishment. In an instant, the soul master corps' position was thrown into chaos with chickens flying and dogs jumping.
The soul engineer corps of the Sun Moon Empire all had vassal armies. After all, soul engineers were noble, and someone was needed to do the dirty, tiring work.
That was the purpose of the vassal armies.
