Deviating from international routes by more than 300 nautical miles. The east and west ends of the island are separated by ridges of dense forest - the east end has white sand beaches, caves, reef fishing spots, freshwater pools, and the three women rescued by Gao Chen, as well as an environment suitable for survival; the west end only has reef bays, simple concave cliffs, shrunken springs, harsh conditions, and seven female victims who rescued themselves to the island. There are coconut groves, breadfruit, wild bananas, wild boars, seabirds, land crabs, and abundant marine fish on the island. Tropical climate, divided into dry season and rainy season, with storms in the rainy season. It is impossible to be rescued in the short term (off course + limited beacon power + search and rescue window has passed). This is a closed stage that requires long-term survival. Gao Chen integrates the two camps of the east and west, leading everyone to fight against nature on an isolated island and survive easily.
