Then Yan Fei looked up at the dome above and noticed traces where a hole had once existed. However, new rock and silt had filled the hole up. From the looks of the scene, it seemed like something had fallen from the sky, piercing through the dome above and landing right in this lava lake.
Yan Fei began to speculate that the black sphere could not possibly be a natural product of the lava. It most likely had fallen from the sky, then smashed through the surface to end up in this lake of lava. As to whether it was manmade, Yan Fei could not tell at all. Then, he began to observe the several pieces of black rock nearby, only to find out that they were indeed just rocks, floating in the lava.
Yan Fei jumped from the black sphere onto a nearby black rock and immediately felt the heat beneath his feet. It was so intense that, even though he could control his body to dissipate the heat, it was nearly unbearable.
