Although the Heavenly Demon Great World's realm is vast, it cannot allow all the armies of the Biluo Alliance to enter.
Except for the initial corps that participated in the war and charged in to confront the Demon Clan, subsequent forces from various worlds were no longer allowed to enter on a large scale.
Especially after the Demon Emperor's demise and the Demon Clan's complete defeat, there was no longer a need for the subsequent armies to come in for support, thus the greatest benefits were taken by these initial charging troops.
And the most advanced and bravest army, undeniably, was the alliance's Four Great Worlds.
Several high-rank worlds, too, had bravely occupied some tribes and territories of the Demon Clan, thus obtaining benefits second only to the Four Great Worlds.
