The heroine Mo Lingxi is a rare "soul painter" in the world, who can turn the things she draws into real existence in her own painting space. In an accident, her blood activated the ancient divine scroll, which not only opened up the portable space, but also summoned and bound the sealed demon of all realms - Cangxuan. Cangxuan was powerful and domineering. He regarded Mo Lingxi as his own and began to pursue and control her vigorously. Mo Lingxi is obedient on the surface, but in fact she uses the space of the scroll to develop quietly. She draws spiritual pills, magical weapons and cute pets, and even creates people loyal to herself. Step by step, she builds her own paradise in an attempt to get rid of Cangxuan. The main plot revolves around the "cat-and-mouse game" between the two. Mo Lingxi continues to grow stronger, from being able to draw only small objects to being able to draw a small world; while Cangxuan is chasing and controlling, attracted by her unyielding soul and endless ghost ideas, and gradually evolves from the initial possessiveness to deep love and protection. The highlight of the plot lies in how the heroine uses the unique ability of "Space Scroll" to outsmart and upgrade in desperate situations, as well as the hero's "genuine" transformation from a domineering devil to a loyal dog husband.
