Those bat monsters, if they had just arrived at Blue Star, might have initiated a battle upon encountering the Blue Star humans, but now they were about to return home and naturally did not want to cause any further trouble.
After all, although the humans were gathered not far away on the water surface, the Plane Return Teleportation Array was in the sky, and as long as the humans lacked means of aerial attack, even if many humans gathered on the sea surface, it would have no impact on them.
Perhaps because they were already carrying a large amount of materials, the bat monsters, upon seeing the humans gathered ahead, chose not to engage them and rose into the air to increase their flying altitude, preparing to wait in the sky for the Plane Transmission Channel to open again.
The bat monsters being able to see the humans obviously meant that the humans could also detect such a huge bat monster army.
