Bab 489: The World Key

"He is truly insane. "thought the devil. 

"I cultivated the art which was named Pain Ascension and fortunately, it seems that I am very compatible with the art since I was able to cultivate all the six stages it had to mastery in a matter of days. I maters it and even begin on working at improving this art. You should be honored since you will be the first person I test this art on. "said Kai Syaoran. 

The devil showed no change in expression. 

All the injuries inflicted to its face just a minute ago had already healed and even the teeth had grown back to normal. 

Kai Syaoran was impressed by this healing ability but he was sure that it was still below his own. 

Slap, slap, slap, Kai Syaoran delivered three consecutive slaps to the devil. Each slap sounded like the arrival of thunder and while using Pain Ascension, the pain was multiplied ten times over.
