The Yuan army defeated Fancheng and massacred Xiangyang, and half of the country in the Southern Song Dynasty fell. Lin Fu, a student who bore the blood feud of his family, led the Qin garrison through troubled times. He raised his arms at Black Stone Crossing and shouted: "Destroy the Yuan invaders and restore the Central Plains!"
Han Lie's tiger-headed sword split the passage, Yue Ting's Liquan gun pierced the Yuan army's array, Xin Muzhi's ambush smoked up the smoke in the valley, and Zhuge Chengyan's strategy united the anti-Yuan forces in the south of the Yangtze River - the old Song army troops, knights and gentlemen who had been scattered in the past, all gathered under the banner of "Reviving the Song Army".
Boyan led an army of 200,000 to suppress the border and surrounded Heishidu in three ways; Lin Fu stayed calm in the face of danger and dispatched his generals: Yue Ting attacked the middle road, Xin Mu blocked the west road, Han Lie dragged the east road, and he personally led the main force to fight Boyan. On top of the mountain of corpses and the sea of blood, Lin Fu, whose iron sword was stained with blood, finally welcomed the cheers of "Long live the king".
This is a desperate counterattack by the descendants of famous generals in the late Song Dynasty. It is a heroic song in which heroes fight decisively on the battlefield in troubled times and end the turmoil.
