Today's episode features a massive former residential complex on Yagou Island, once a thriving coal mine settlement but now an abandoned island. Jun receives a video message on his phone from a bandaged man in a wheelchair claiming to be from the future.
"Everyone is going to die." Yagou Island has a legend surrounding it. The locals say that the island is a forgotten land, an island that does not know time.
