Those horrifying beasts did not stop moving after that. Every movement posed a danger to many of them until suddenly, one of them cried, "NOW!"
Although none were privy to each other's thoughts, they all agreed on one thing: They had to survive.
If one was going to attack, then they would all do it to at least have the slightest chance.
Soon, powerful items and myriad laws and powers were shooting back and forth. Some were aimed at those horrifying beasts, others seemed to be aimed at the castle, and others were directed at the primordial treasure.
Such a sudden explosion of diverse powers made the primordial treasure, instead of feeling astonished, smile. He was expecting that. The more they resisted, the better it was for his personal enjoyment.
That's why he let all those attacks hit wherever they wanted. He didn't care about defending the castle, his horrifying beasts, or himself.
