Beggar So sends Foggy to a sickness teacher for herbs to cure him, and the doctor teaches him a dreaded style called 'Sickness Boxing'. Now, armed with this sick form of fighting, Foggy is ready for Drunk Mantis.
In the end, Foggy goes berserk and kills Rubber Legs. Unable to escape from his trance, he sees Rubber Legs when he looks at Beggar So and attacks him.
