I only know the mystery of dead island and the mystery of the century. I have this book, which is also available in various Xinhua bookstores, but the names of the characters have changed: Fokko = Cat Nine Bean Skin = Xiao Pi Dimple = Sweet Tang Koala = Ai Guo Cute Fox = Long Zaitian Pride = Zhu Gang Surprisingly = Li Dalong. Cat Nine is a woman, Long Zaitian is a man, and the national treasure is: Peking man's skull.
