As soon as Luca arrived at the royal palace, he wasted no time summoning all the King-rank demons in the North. He then informed the emperor that he was ready to perform the essence transfer ritual.
It seemed the emperor had been waiting for this moment for a long time. Without delay, the emperor immediately began separating her essence from her soul.
This caught Luca slightly off guard, as he hadn't expected the ritual to begin so suddenly. Still, he transformed into his black dragon form and let out a powerful roar, summoning all the King-rank demons from the three regions.
The essence transfer ritual required the presence of at least two King-rank demons as witnesses. Although the two Kings of the North would have been sufficient, Luca gathered them all to prepare for the coming battle.
Once everyone had assembled at the teleportation circle and the emperor had completed the separation of the inheritance essence, Luca returned to his human form.
