Noah didn't give other orders, but the Elders didn't need more directives. His call for war was enough to activate all the parts of the Hive that could help in battle.
Chasing Demon had taught Elder Julia how to handle the Copying Technique, so she set off to hunt more magical beasts. She even relied on Noah to make use of his expertise in the magical beasts' field.

Of course, that wouldn't be enough to stop the Royals' leader. A powerhouse in the solid stage who used only higher energy couldn't lose against an army of weaker beasts.

Flying Demon had learnt how to create doors in the separate dimension, so he handled the creation of specific tunnels that could give the allied forces an edge over King Elbas.
