Chu Li sat in his little courtyard whilst using the Omniscient Mirror to observe King An.
A King An without martial arts was a good King An. He dared not kill him but still dared to cripple him. Chu Li intended to keep him that way.
King An without martial arts was a man without a backbone, unable to create havoc. He would not be able to act with wanton aggression. No matter how much his spirit craves it, his flesh would be too weak to eliminate him.
With the Nine Dragons' Tripod Cauldron, his martial arts would recover quickly, and he probably would not despair for long. Rather, when the going got tough, the tougher got going. He would soon regain his spirits and recover his martial arts without allowing his focus to wander. After cultivating, he would cultivate some more. He would not come out and disturb others.
