Modern warships of the technology side rely on a combat command automatic control system to manage the ship's commands, communications, navigation, target identification, and weapon launches.
Placing this sort of system on an alchemy ship would correspond to the Alchemy Sage who controls the Sage Space.
The Alchemy Sage has control over every detail of the Sage Space.
He can observe everything around him through the alchemy array on the outer edge of the Sage Space, completing navigation and target identification tasks.
With just a thought, he can adjust the mechanical devices of the Sage Space to give orders to crew members located throughout the ship, which in turn, guide the crew to operate the alchemy cannons and launch attacks on targets.
It can be said that when alchemical constructs become advanced enough to replace crew members, these alchemy ships, transformed from the Sage Space, will usher in an era of Alchemy Sages fighting solo on the sea.
