At the end of the Battle of Gods, the Demigods on both sides of the conflict began to retreat around the headquarters of the Black Plain Army.
The aliens' plan was to try to force the enemy forces back and look for a way to eliminate Abby. But since the alien Gods had failed in their plans, it would be a waste of strength to continue to fight the Demigods.
Thus, the group of 10th-stage aliens soon began to disperse while the Demigods of the local forces attacked with vigor to take out as many of the retreating enemies as possible.
The local Demigods were not as strong as the same-level enemies. However, thanks to the many Demigods that Abby had resurrected, the local forces had the support they needed in the final minutes to inflict heavy casualties on the enemy side.
Of the thousand or so 10th-stage aliens that attacked this base moments ago, 400 fell by the time the alien retreat began.
