The room on the screen was made from layers of nine rare treasured materials: Celestial Bronze, Adamantine, Gallium, Chronoton, Vajra, World-mending stone, Xinite, Misolzinyl, and Timonium. This ensured the radiation from the casket and Cosmic Spark didn't sweep out, protecting other areas from destruction.
From the walls and ceiling, hundreds of laser beams boomed out, attacking a single spot on Cosmic Spark. Each beam was as thick as a filament but it carried destructive power enough to eradicate an entire solar system.
Yet the collision of hundreds of such beams didn't create a single scratch. Colorful lights bloomed out along with destructive waves, colliding against the walls, resulting in explosive sounds.
Time passed, perhaps decades or centuries, and finally a shard fell from Cosmic Spark. The shard was as thick and long as a fine hair, and as soon as it fell, a spatial force emerged from one of the walls. The next moment, the shard was teleported out of the room.
