After the humiliation of Jingkang, Bianjing fell, and the story of the Yang family's loyal generals became a legend among storytellers.
In the slums of Lin'an City, young man Yang Jin was awakened every night by the nightmare of "seven sons going away and six sons returning". The rusty half-iron gun at his waist was the only thought he dug out of the ruins. It wasn't until that rainy night, when the Jin Kingdom secret agent's blade cut through the night, and the one-armed veteran screamed "Yang's gun keeps on" as he tried to protect him with his life, that he saw clearly that there was more than just blood secrets hidden in the barrel of the gun - the blood book and defense plans wrapped in oilcloth were enough to overturn the chess game of Song, Jin and Meng.
From the flash of swords on a rainy night in Lin'an to the remains of Yanmen Pass; from the "rebellious" blade of the Dongting Lake rebels to the wordless monument in the solitary tomb in Mobei; Yang Jin, carrying a half-iron spear, broke through the conspiracy of Pan Renmei's descendants, awakened the enslaved Han dead, and even fought side by side with the Jurchen tribe against the Mongolian cavalry.
He gradually understood that the "loyalty" of the Yang family generals was never to guard the Zhao family's world. When the Mongolian iron hoofs trampled the Yellow River, and when the Song Dynasty wavered between peace and struggle, Yang Jin raised the remaining spear, and behind him were the refugees' hoes, the rebels' knives, and the Jurchen axes——
"For three hundred years, the blood of the Yang family has never protected any dragon flag, but the people who are willing to stand alive on this land!"
Where the remaining spears and armor were broken, they were all filled with Chinese souls. This is a revenge epic that transcends loyalty to the emperor. An iron spear stained with blood for three hundred years is intended to open a way for China in troubled times.
