In the second year of Tianqi, Liaodong was in danger. Sun Chengzong was ordered to face the danger, and built the Guan-Ning-Jin defense line with his iron-blooded will - the lonely city of Ningyuan stood tall, and the Jinzhou Fortress was like a blade unsheathed, forcibly erecting a flesh-and-blood Great Wall for the swaying Ming Empire. With his keen eye, he promoted Yuan Chonghuan, Zu Dashou and other powerful generals, and tempered the powerful Guanning Army in Liaodong. He also used the strategy of "defense as war" to advance the lost territory for more than 200 miles, making Nurha Chi hate Ningyuan and Huang Taiji's defeat in the capital.
However, the strife in the temple is like a knife, and Chongzhen's suspicion is like a net. Even though he supervised the army twice and tried his best to protect the country, he was unable to defeat the enemy because the court was dim and the food and salary were cut off. The tragedy of Daling River ruined the last ray of hope for counterattack.
In the eleventh year of Chongzhen, the Qing army broke through Gaoyang. The seventy-six-year-old white-haired commander led all the women and children in the city to die in a bloody battle. Hundreds of households are closed, and the setting sun is stained with blood.
——He is the pillar supporting the sky when the empire is about to fall, and the lone loyal singer in the dark night. The bricks and stones of Guanning's defense line are engraved with his strategy, and the wind and dust of Yanzhao land are whistling his tragic story. One part is the history of Sun Chengzong, and the other half is the tears of death of the Ming Dynasty.
