Chu Liuxiang and Zhongyuan Yidianhong pass by a shipwreck and meet Master Kumei. They also discover that a group of highly skilled pugilists have been murdered at a gathering in Siming Mountain Manor. The only survivor is a man called Yuan Suifeng, who has become insane after being severely injured. They hear of Bat Island, a mysterious place where anyone can buy anything he desires, as long as he has money. Chu and his friends travel to the island to seek answers. However, they are not the only ones going there: Li Yuhan and his wife, Liu Wuming, are there in search of an extraordinary drug; Jin Lingzhi is there to find her father; a group of imperial guards are there to arrest the Bat Prince.
