The inner ocean, which was enclosed by the Ring-shaped Island, covered an area of five miles in a straight line. While Nimr stood at the edge of its own island, it could barely see the outline of the island to its opposite. It threw its glance over to the islands one after another and could see the busy figures of its clan members everywhere, yet it saw more juveniles who were swimming in the inner lava ocean, playing and chasing with each other. Though it was a little bit noisy, it actually made the clan look more lively and full of energy.
Right as it was about to shut its eyes, trying to sense the possible direction where the danger might come from, far at the Southeast border of the Ring-shaped Island, an unprecedented explosion suddenly broke out. A rock wall of nearly one hundred meters in circumference shattered into pieces, shooting countless rocks fragments and debris like a shower into the lava ocean and causing a massive flame and dust pillar to rise up.
