Of course, the most important aspect of a floating city was establishing its own magical domain.
This was the most fundamental requirement for legendary mages building floating cities.
A floating city was a spellcaster's divine kingdom.
The earliest floating cities had been built after spellcasters deciphered the divine kingdoms of gods.
A god's divine kingdom imposed rule-based suppression upon all foreign invaders. Invaders found it difficult to wield the rules, could not absorb mana, and saw both their combat strength and spell power diminished.
Meanwhile, gods received enhancements within their own divine kingdoms. With one side strengthened and the other weakened, even enemies originally of the same rank could not defeat a god within its divine kingdom.
But with a floating city, things were different. Once Huo Ling's floating city activated its magical domain, it would directly drive out all other rules.
It would establish its own domain throughout the surrounding area, and within that domain, all allies would receive enhancements out of thin air.
These enhancements manifested in every aspect: greater strength, faster speed, stronger magic resistance, improved physique, and faster recovery of battle aura and mana.
Huo Ling had even specifically constructed numerous shield generators. If the soldiers going into battle were lucky enough, they could even receive the blessing of shields within the magical domain.
Once Huo Ling activated his magical domain, it could directly cancel out the enemy's advantage within their divine kingdom. Within a divine kingdom, gods had their own domains, while the floating city also had a domain.
When the two domains collided, they would undoubtedly consume vast amounts of energy, but Huo Ling was not worried.
Huo Ling had plenty of energy, while the enemy's divine power diminished with every bit they used.
With this floating city, Huo Ling could pick a fight
