The History of Song: Biography of Wu Jun
Wu Jun, courtesy name Zhenjie and sobriquet Master Zongyuan, was popularly known as Master Black Sheep. He was said to have lived during the reign of Emperor Xuanzong of Tang, and to have been over three hundred years old.
In the eleventh month of the sixth year of Zhenghe, Chage, Prince of Jin of Western Xia, besieged Anping Stockade in Qin Feng Circuit and cut off its water supply.
Guo Haocha, military inspector of Weizhou, led three hundred cavalrymen to scout the enemy. They were ambushed and fought desperately but were outmatched. An arrow struck Guo Hao in the left cheek, and he was near death.
Jun descended to earth aboard a celestial vessel fifty li northwest of Anping Stockade in Qin Feng Circuit. He slew more than ten thousand enemy troops and rescued Guo Hao from the midst of their vast army.
Wang Hou combined the forces of Jingyuan and Qin Feng, a hundred thousand troops in all, to attack Zangdihe City. The siege dragged on without success, so Tong Guan, Commandant of the Imperial Guard, ordered Jun to assist. The city fell soon afterward.
Tong Guan reported the victory, and the emperor was delighted. He summoned Jun to the capital and appointed him Envoy of the Divine Empyrean Palace.
In the second month of the second year of Jingkang, the Jin besieged Dongjing again. The emperor trusted Guo Jing's method of defending the city with the Six Jia. Jun hurried there, striking Guo Jing dead with heavenly thunder. But the situation was dire: the city fell, and the Jin troops seized the two emperors and carried them away.
In the tenth year of Shaoxing, Emperor Gaozong stripped Yue Fei and Han Shizhong of their military commands and imprisoned them. Knowing what was happening, Jun rushed down the mountain, but the palace guards tried to stop him. In the court, Jun shouted, “Watch me hack Qin Hui to pieces first, then flay Wanyan Gou alive!”
Without changing the Jingkang Incident, it's pointless and there's nothing exciting about it.
