When he watched the crystal for ten minutes, he noticed a sudden change in the movement of the spirit power. Spirit power was in pale gold colour, looking like lots of tiny sand dots swirling inside the crystal, taking the shape of the fox.
Yet after ten minutes, he saw these dots change their movement, disturbing the fox form, and showing a weird shape of something he never saw before.
It just happened for a brief second before everything returned back to normal. After another ten minutes, the same thing happened again, confirming what he saw before.
"This… These two damn spirits… They are trying to do something with my fox!!!" When it happened for the third time, William was sure the two new spirits weren't dormant or sleepy at all.
They were slowly doing something, something that he didn't recognise. He tried to grasp the thing they changed his spirit power into but couldn't.
