Friends in the parallel world tried their best to keep the heroine Su Wan alive.
That ray of spiritual power fell into the Republic of China - into a war-torn era, and into the body of a girl named "Shen Jingxi".
She is a descendant of the Suzhou embroidery family, and she and her three sisters depend on each other in troubled times. They use needles as swords and threads as life. What they embroider is not only flowers, birds, fish and insects, but also a country in the broken mountains and rivers.
On the other side of the parallel world, friends are using all their resources to find her, call her, and wait for her to come back.
Concept: Needle and thread can embroider mountains and rivers, but they cannot embroider people's hearts. Across time and space, there is always someone waiting for you to come back.
