Cen Ye is the commander of the border special operations team. He is cold and decisive and believes in "it is better to kill by mistake than let go." During a night raid, he personally shot and killed an officer disguised as an enemy soldier, and his body was burned in a trench. Three years later, the enemy raided the base, and a commander wearing a silver mask led a counterattack with sharp marksmanship and a sound like cold iron - it turned out to be the Major General Lu Zhao who was "buried" by his own hands that year. Lu Zhao was not dead, only disfigured and voiceless, but he used his body to regain military power. He returned only to find out the truth: who was behind the cover-up of the defection case? The two of them were facing each other with swords. They used to be great enemies, but now they are mortal enemies.
