The wind in southern Xinjiang carries yellow sand and gunpowder smoke, and the cold light of the sharp blade cuts through the fog. A group of warriors with unique skills, using faith as a shield and blood as a blade, shuttled through the mountains on the border and stood firm on unknown battlefields. They are the sharp blades hidden in the south wind, hidden in the darkness, protecting the safety of one side; they build the Great Wall with their flesh and blood, and go on their missions alone, letting the edge of justice always chase the direction of the south wind. Every attack is a desperate decision; every return is a safe answer. This is their iron-blooded journey, and it is also a heroic epic engraved on the land of southern Xinjiang.
