Suddenly, an amusement park was built in Adventure Valley, and almost all children were attracted by the highly publicized advertisements of the amusement park and flocked to it. But what is incredible is that the man-eating monster machine in the amusement park located in Adventure Valley is actually real, swallowing many children. Moreover, as the investigation continues, people have also discovered some astonishing secrets in the amusement park, such as: the fake sea dozens of meters deep is actually filled with ghostly figures; in the dark underwater tunnels, there are actually two huge orange eyes flickering; in the artificial lake of this book, there is actually a floating black head; in the terrifying vampire castle, there is actually a strange old man wearing a monk's robe living. These secrets attract the young detective Yak and his friend Weirui to go to the bottom of the lake tunnel to find the man-eating monster together, but when they get ashore, they are shocked to find that Weirui has mysteriously disappeared. Later, Yak was also locked in an underground water prison by the evil owner of the amusement park. We really want to know, can Yak successfully escape from danger? Can he solve the mystery of the monster? Who is behind all this? Are there really ghosts in the world?
