In the winter of 1940, the Japanese Yamamoto Special Forces launch a night raid on Kong Jie’s Independent Regiment in Yangcun, inflicting devastating casualties. The senior commander furiously berates the unit as a “doughy mess.” But Kong Jie, dismissed from his post and transferred elsewhere, refuses to give in. In seclusion, he reviews the battle and uncovers the truth about the enemy’s elite forces from an unusual cartridge case. He devises a plan to defeat them over maps and sand tables. After lying low for a time, he returns to the battlefield and takes command of the New Second Regiment. Using himself as bait, Kong Jie lays his plans with meticulous care. The rebellious Li Yunlong is his iron fist, the far-sighted Ding Wei his shield, and even the aloof Chu Yunfei becomes part of a pincer formation. A vast net of revenge and annihilation is quietly spread across northwestern Shanxi. When the Yamamoto Special Forces bare their fangs again, they have already fallen into a carefully constructed trap. Amid a storm of artillery fire, Kong Jie commands with cool precision, and the soldiers who once routed have become an iron army. Then, during the sweeping campaigns to break the encirclement that follow, he joins his comrades in showing the Japanese what true “Sword Unsheathed” spirit means: not just the bravery to face an enemy in a narrow pass, but also an unbreakable resilience and the wisdom to turn the tide. This is an epic about a blunt blade. It has no dazzling edge, yet through quiet honing it can shatter every invading enemy. Follow Kong Jie as he walks through blood from the depths of defeat and transforms into a true commander amid the flames of war, forging an enduring legend of his own.
