If we want to destroy the Sky Holy Palace, we must first destroy all the Dragon Temples on the ground, as they are supported by divine power.
And to destroy all Dragon Temples, we must first eliminate the Human Kingdom.
To wipe out the Human Kingdom, the first step is to destroy the Motuo Empire, as this is irreversible.
Of course, the coastline defenses of the Human Kingdom are currently very weak, and the fleet of the Flame Demon Empire can obliterate all the Human Kingdom's navy within minutes and begin their landing.
However, the Human Kingdom is a domain of the Dragon's power and does not belong to Demon Emperor Lanling's plane but to his enemy's plane. Once Lanling and his army enter the Human Kingdom, they will be weakened and burned by the power of the Dragon.
Moreover, the Motuo Empire borders the Human Kingdom!
