Kai smiled as the light from all the lasers filled the dome believing the monsters where done for just then he sensed an immense darkness and blood lust coming form Rika although he didn't know it was him at the time. As the light faded he saw the monsters just standing absorbing the energy like he was "ok... so that didn't work" as he said that his six drones returned to his side while the other floating  crystals and even the dome deconstructed themselves creating billions of razor sharp crystal shards. Kai then sent them at the four monsters from all directions in a massive barrage that looked more like a crystal hail storm this would continue for about ten minuets.
