The first thing Kai Syaoran did was form soul spears inside the hall. Since the beastess would easily defend against these spears, Kai Syaoran sent them flying for the other demonic beings within the hall.
The beastess tried to stop these spears but to no avail. Her intent was only to trap the spears for a few seconds before they broke through her intent piercing into the heads of the demonic beasts. Their souls shattered immediately and Kai Syaoran had never turned down a free meal in his life so, he immediately absorbed the soul qi making his soul even stronger. Kai Syaoran needed any advantage he could get against this beastess.
Kai Syaoran did the first thing one does in any war, cripple your opponent in any way you can. He did this by using his soul force to form a giant hairy hand with mighty claws above the village. He then brought this hand down on the town and crashed it like a bug.
Creation is hard, cheer me up!
