In the windy sand of northern Xinjiang, a bookmark under a broken wall tied the lives of two people. She brought the system and met him for the first time, guarding the border. They protected each other with arrows and shared food in the cold night. A secret love grew up and they planted a silver lock. When we walked side by side in the snow, he defeated the enemy and made military achievements and was promoted to deputy general. She was by her side and a pearl was born. The general star gradually became brighter in the smoke. The newly carved pear contains a secret message; the moon is cold in Chang'an, the pear orchard is still crying for joy, the undercurrent of the courtiers has arisen, the cold light suddenly appeared at the palace banquet, she used her body to offset it, and the blood-stained bookmark stopped the flowering period; after that, the pear blossoms bloomed every year, and he left the capital and returned to the north to guard the tomb, watching the young children learn the sword and listening to the pear fragrance's confession. When he was old, he held the double sign and fell asleep, hoping to meet her again on the day of return.
