Lin Xiaochuan, a useless disciple of the Qingyun Sect's outer sect, was regarded as a "waste of handymen" by his fellow disciples due to his natural weak spiritual power. He accidentally activated the "Lying Down Sign-in System" - if you sign in at the designated location of the Immortal Sect (Sword Tomb, Medicine Garden, and Sutra Collection Pavilion) every day, you can receive rewards for exercises, elixirs, and spiritual weapons. When you lie down and catch fish, your spiritual power will automatically accumulate (ten times faster than ordinary people). As the number of sign-ins increased, Lin Xiaochuan's strength improved by leaps and bounds. He successively slapped the hypocritical senior brother, the jealous junior brother, and the green tea junior sister in the face, attracting the attention of many female protagonists such as the gentle female doctor, the bold female bodyguard, the gentle showgirl, and the cold female general. He used funny methods to resolve disputes among immortals, the invasion of demonic armies, and crises in the three realms, and finally became the Immortal King and gained love and friendship.
