Lin Yue, a retired naval scout, was stranded on a desert island after a shipwreck. There is no system, no plug-ins, just a lighter and an old injury. On this isolated island forgotten by the world, he met Aya, a wild girl who lived alone for 188 days. She hunts with a bone knife and records time on the rock wall with charcoal. Her eyes are like a wolf, but she will throw you a coconut when you put down your weapon. When Su Wanqing, a doctor of marine biology, Fang Qing, a professional liar, and Catherine, a war reporter, arrived one after another, five originally unrelated women and a taciturn man formed an unnumbered team in this corner forgotten by civilization. From the loss of fresh water to pirate invasion, from World War II bunkers to the rock walls carved with hundreds of years of carvings deep in the island, survival is just the beginning. The real test is how they choose the direction home when the rescue ship finally appears on the sea level.
