Introduction: Traveling to the barren border of Dayan's northern frontier, Liu Yi activated his childhood animation system with inconsistent painting styles since he was a child, demanding the complete creation of the painting "King of the Riding Blade". While studying the move decomposition map, I realized the unique way of exerting force. An ordinary iron sword can also create air waves. In the white-haired cold winter, barbarians invaded on a large scale, and his grandfather Liu Wei died in battle. The young Liu Yi took up his military certificate and rushed to the battlefield. He turned around and attacked the scattered cavalry with three consecutive attacks. Step by step, he grew from an inconspicuous child in the fort to a border warrior valued by thousands of households.
