After sleeping for ten years and losing all five senses, Han Beita unexpectedly travels to a bizarre land shrouded in mist. Here, everyone starts on equal footing, day and night are reversed, and danger lurks everywhere, with invisible, unknown horrors hiding in every corner. He awakens his exclusive talent, Iron Spine Will, which allows him to trade his sanity for an extraordinarily powerful physique and immunity in desperate situations. Relying on his sole shelter, he unlocks features such as the wishing well and wilderness exploration. In one life-threatening crisis after another, he relies on his unyielding will to break free from fate, tear apart the mist, and survive against all odds.
