The entire school embarks on a survival journey, starting from a primeval rainforest.

[Farming, Hunting, Survival, Gathering, Evolution, Development] This book, also known as "My Saintly System Meets a Heart of Stone," tells the story of an entire university that is transported to a primeval rainforest, a forbidden zone for humans, overnight. The entire campus is immediately submerged in a lake. Piranhas, electric eels, caimans, giant anacondas, poison dart frogs, jaguars... every creature here is a deadly beast; ordinary people cannot survive here for more than three hours. On the first day alone, the entire school suffers heavy casualties, and everyone faces immense survival challenges from the very beginning. As people gradually adapt to the harsh environment, they despairingly discover that this is only the beginning. On the fifteenth day, a small beast tide arrives; on the thirtieth day, a large beast tide sweeps across the entire school. Every month, they are transported to an even more dangerous area, facing even more severe tests. Fortunately, there is always a way out. This world has a homestead system, allowing people to grow crops, mine minerals, forge weapons, conduct combat training, and even... tame dragons in their dormitories! In addition, Jiang Fan awakened a unique [Gratitude System]. Helping others and gaining recognition earns him Gratitude Points, which can be used to draw various card rewards. While others were struggling to survive, Jiang Fan lived a life of unimaginable luxury. When the beast tide attacked and everyone was plunged into despair, Jiang Fan rode a giant dragon, soaring upwards against the sky. The people below were immediately bewildered. "Dude, when did you become a dragon knight?"
