to kill everyone present?

WYZ goes cranky and decides that he wants to kill anyone who might beat him in chess!

His legs are fully functional. Cmon, if HYS could heal his disciple in 5 years (I think or was it shorter), why can't WYZ?

WYZ promises DCQ that if he helps, he would teach DCQ a little more of BMSG, so DCQ bites and helps.

Would Wu Ya Zi succeed?
