Just after the edict of exile was read, the deposed prince Xie Linchuan was thrown into the abandoned camp of Fengsha to die. On a snowy night, he rescued a hypothermic child, but the first future order popped up in front of him: Twelve days later, the emperor who personally exiled him would secretly purchase 5,000 pairs of life-saving military boots.

Abandoned warehouses, moldy wool, thirty-seven refugees, a border supply crisis, and a comeback started from the first pair of boots.
