After pushing the Golden Horn Breathing Technique to its maximum, Levi did not immediately start assembling and mutating it with the Black Snake Breathing Technique.
He spent a few days adjusting his condition to its peak. This was the first time Levi had broken through the limits of a legendary-grade breathing technique. He did not know what would happen next, so he could not help but feel a little nervous.
On Black Fire Island, the Swordsman Mantises patrolled around the clock. The Seven Generals of the Living-dead Family hid in the dark, ready to deal a fatal blow to intruders. The Poison Fire Bone Snake, Igor, also guarded the island from his cave. Traces of colorless and invisible energy crisscrossed and surrounded Levi's cave. Once an intruder broke in, an alarm would be triggered.
Black Fire Island was now impregnable. In this region, no one could trespass onto the island aside from the Second-Circle Wizards from the large organizations.
