Ye Fei was living an ordinary life until, overnight, he transmigrated to an unknown world shrouded in mist. The mist never lifts, and every inch of air reeks of death. Hunger, cold, and wild beasts could take his life at any moment.
Amid the chaos, Ye Fei meets Zhang Kaiguan, a timid but loyal man. They support each other and find a glimmer of hope in a dilapidated wooden hut, then struggle to stockpile supplies and build a shelter. During their explorations, they discover a mysterious ruin. Just as they are about to uncover the truth about this world, it draws the frenzied attention of rival factions.
On one outing, Ye Fei rescues Liu Jingwen, who is being hunted. This woman, an expert in wilderness survival, brings new hope to the group. They also meet Li Ze, who is struggling to survive with a child in tow. Li Ze gives everything to protect the child, yet still feels powerless in this desperate situation.
The five of them join forces in a world of eerie lights and shadows, plagued by deadly "mist tides." As they search for a way to resist the mysterious forces, they push toward their goal of breaking the world's rules and returning to reality. Thus begins a thrilling fight for survival against impossible odds.
