In the wasteland after the red mist disaster in 2123, Lin Chuan, a grassroots city hunter, was accidentally bound to the "Lieping Sign-in System" - you can gain cultivation by lying down (sleeping or dazing), and you can get props/skills by signing in at wasteland ruins, mutant lairs and other places every day. He started by building a small safe house, and gradually upgraded the safe house to a safe city through lying down, becoming stronger, and signing in to expand. Finally, he revealed the secret of the red mist, solved the world crisis, and became a legend in the wasteland.
