On a snowy night at the border gate, when the crazy blood broke through the formation, the lone blade cut off all the doubts in the world. Qi Xiao, the former army commander who was denounced as a madman, held a broken sword in his hand and his armor was stained with blood; Wei Jin, the leader of the dead soldiers who was as silent as iron, sealed his throat with a sword, regardless of cause and effect. The two were originally enemies of life and death, but when the smoke suddenly rose in the north and the undercurrent in the court surged, they were forced to join forces to defeat the enemy. When hundreds of thousands of cavalry press the border, and when the court wants to abandon the border, they are the only ones who, with their lives as their guide and their blood as their oath, tear apart the facade of this conspiracy. Crazy blood is not madness, but the loyal soul is still alive; being alone is not alone, it is the support of close friends.
