Wei Wu, the commander of the border army, was not allowed to be promoted for ten years after leading the army. When foreign invaders invaded, the commander abandoned the city and fled. He led thirty of his men to guard the city gate and held the enemy troops for three days and three nights. The news spread back to the capital, and the emperor made an exception and promoted him to general. He took over a remnant army that was short of food and pay, and wanted to use this army to regain the fallen thirteen states. And the dignitaries in the court are plotting to kill him before his victory. Can a knife sharpened by the wind and sand at the border cleave the hidden arrows in the court?
