The Protection Army on the ship quickly reacted, starting to eradicate the heroic spirits here.
They certainly couldn't hold on for long, but when Alfonso's Protection Army set their sights on them and took action, their goal was actually already achieved.
However, the commanders of the Protection Army were no fools. They would soon realize that the heroic spirits they eradicated were insufficient in combat strength and numbers to annihilate those patrols, not allowing a single survivor or any information to be transmitted.
Furthermore, the Phoenix's actions hadn't stopped, and in areas far from here, there were still patrols that needed resolving. Their disappearance would further alert the enemy.
The Protection Army would sooner or later become suspicious and speculate that a formidable force had arrived, using the increased area of patrol disappearance to roughly judge what this force intended to do.
