While traveling in Changbai Mountain, college student Luo Xiangbei encounters a terrifying bear. He initially thinks it is just an ordinary disaster, but soon discovers that he is trapped in an endless death-loop instance. Using his ability to rewind time upon death, he endures countless gruesome deaths and repeatedly loses memories of the person he loves most. From the snowy wilderness of Changbai Mountain to a cyberpunk reality, he fights his way through everything to rescue his lover, whom the system has classified as 'fictional.' But after finally tearing through every obstacle, he discovers the shocking truth: he is nothing more than Clone No. 1001, created by someone solely to complete a mission.
