Kai Syairan began by agitating his soul core to vibrate slowly. He then did the same thing with his source core. As for his body, it did not have a specific core. In all his books, the body itself was the physical core.
The three different cores began slowly but soon, they were vibrating so fast that the normal eye could not keep track of their movements.
Kai Syaoran's body looked to be nothing more than a blur. A mysterious energy began flowing in Kai Syaoran's body.
His meridians felt refreshed and his mind became clearer.
He felt the heavenly rejection start lessening.
He felt the kaws start moving back to his previously abandoned body.
This showed that he was on the right track. He would at least survive the ordeal but Kai Syaoran still felt discontent in his heart.
He did not know the reason for his rave but he knew that he was about to explode.
