Mo Lin, a game programmer who died suddenly from overwork, transmigrates into another world and becomes Jiahao, a worthless sorcerer bullied by everyone. Just as he prepares to rise to the top, the original owner of his body transforms into a sleep system. By completing bizarre sleep missions, he can level up and obtain powerful gear. But whenever he gets carried away and recklessly takes on dangerous adventures, a pillow forcibly shuts him down. While everyone else bleeds fighting monsters, he simply wakes up and finishes the job. However, as the chaos threatening to engulf the continent draws near, he discovers that neither this transmigration nor the other soul inside his body may have been an accident.
