The young general Mu Ziyu strayed into a foreign land full of pear blossoms and met a Taoist priest named Mu Ye who was dressed in blue and wore a pear hairpin. After a brief encounter, they parted ways, but when the situation in the world rose again, they met again in the night of the massacre.
A "heavenly book" that can control the wind and rain, and whoever wins the hearts of the people wins the world, involves the bloody old hatred of the disciples who were massacred five years ago. As the only heir to the Book of Heaven, Makino carries the legacy of his master and the secret of the tragic death of his fellow disciples, and walks alone among the pursuits and plots in the world. Mu Ziyu, with her sincerity and determination, insisted on standing by his side.
From the Lihua Forest to the suspicious clouds in the Song Dynasty, from the arrow rain in the martial arts competition to the Yuan Shen Sacrifice Formation in Beimang Mountain, the two supported each other on the edge of life and death, and their love grew from secret to the confession of the dike. In order to break the formation and save people in Beimang Mountain, Makino turned his soul into stars and disappeared in the sky. Mu Ziyu spent two years traveling thousands of miles across mountains and rivers, searching in despair and longing.
Finally, under the pear tree where they first met, the man shared the flowers and walked on the scent, returning as promised.
