Yun Chuheng was pregnant with cold poison from her mother's womb, and the imperial doctor said she would not live to be seventeen years old.
The emperor and the empress ordered the king of hell, Xuanyuan Lin, to escort her to Tianshan Mountain in search of medicine.
He thought she was troublesome, and she was afraid of his aura, so she was silent all the way.
Later, he blocked arrows for her, picked ginger for her, held her hand and performed kung fu to warm her body when the cold poison broke out, and guarded her all night - he just took it as responsibility.
It wasn't until another man came closer to her, and his whole body was completely cold, that he finally realized that he might have been tempted.
After his return, he rushed into the palace covered in dust and knelt in front of the emperor and empress: "I am willing to spend half my life's military service in exchange for this piece of paper to grant a marriage."
