Xiu had already noticed the exhaustion of the alliance army. If it continued, the alliance army would be defeated by the Devil Race.

Therefore, he made the decision to strategically retreat at a critical moment and handed over the burden of resisting the devil soldiers to The Rising Sun City's defensive shield.

They couldn’t hide forever in The Rising Sun City, however. The Devil Race would one day break the defensive shield, and once they started fighting again at that time, the Barren Land would have no room to maneuver.

Relying on the war of attrition strategy, they were able to continue to consume the forces of the Devil Race, and by fighting them, they further depleted the devil army. But right now, the alliance army needed to rest, and it was also time to test The Rising Sun City's defensive shield.
