Regardless, the Blood Fortress was still one of the three Floating Cities and, in terms of size and combat power, was only slightly inferior to Stania.

Such a massive object moving in the sky couldn't possibly go unnoticed.

As soon as the Blood Fortress began to retreat, Otto discovered it.

At this time, Otto was testing the specific function of the Dragon Crystal.

Seeing the Blood Fortress about to flee, he immediately ordered the Blackstone Floating City to follow and took to the sky himself with a fast flap of his wings.

A floating city was a valuable asset; he couldn't let it escape so easily.

With that thought, Otto's flying speed instantly reached its peak.

However, before he could approach the Blood Fortress, a thick bolt of lightning struck down from the sky, landing on his back with incredible force.

Although this kind of attack couldn't cause any substantial damage to Otto, it inevitably forced his flying altitude lower.
