He then explained to him, "The first one is by destroying their energy source. Underneath this liquid metal that can take on any appearance is a purple crystal that you just have to break to make these creatures disappear.
It's probably because you aren't powerful enough yet that you can't discern them, but I can assure you that they all have a purple crystal and that thanks to our weapons it will be a piece of cake to kill them.
The other solution is more extrem and it is to disintegrate these creatures using the sacred fire energy."
As soon as he finished speaking, red flames with golden outlines appeared on the short swords and Alanis ordered them, "Kill !"
His short swords immediately charged at the creatures and Mika saw them either pierce their chests or disintegrate them with the sacred fire energy.
