Gu Wantang never thought that he would be closely connected with the Yan Dynasty a thousand years ago because of a child in ancient costume picked up on a rainy night. The little guy asked his mother one after another, and brought a silver hairpin and a letter for help out of thin air - on the other side of the letter, the prince Xiao Linyuan, who had been chased by the emperor's uncle after he usurped the throne, was trapped in the barren valley with his remaining soldiers. He was short of food and medicine, and could not survive this winter. Gu Wantang originally just wanted to send some food and medicine to save lives. Food, medicine, and warm clothing, but the supplies that traveled through time and time again turned barren valleys into villages, made houses grow out of ruins, and allowed soldiers trapped in the mountains to hope for tomorrow again.
