In the game Sword Network Three Swordsmen Love Affair, there is an army called the Xuanjia Cangyun Army, whose predecessor was a heavy army called the Broken Array Army led by Xue Rengui's descendant Xue Zhi.
They guarded yanmen pass for the Tang Dynasty, but at the same time they were regarded as a roadblock by an anandandr and other rebels, so An Lushan provoked a border war in order to eliminate the Xuanjia Cangyun army, and when the Cangyun army was struggling to fight, An Lushan led the rebels to sneak up from behind and kill Xue Zhi.
Later, the remnants of the Broken Formation Army, under the leadership of the original deputy commander Sun Yiqing, established the Cangyun Army, still fighting for the protection of the Tang Dynasty. But in fact, this iron-blooded army is not only a fictional army in the three games of the sword net, there are also many records of the Cangyun Army in history, the most famous of which are two battles, one is the Battle of tiger prison, the other is the battle of Hengluo.
The Battle of Tiger Prison was a major war in the cause of tang unification, and its victory not only solved the threat of warlords such as Wang Shichong and Dou Jiande for Li Yuan's rule, but also marked the basic end of the tang dynasty's unification steps. In this war, the Xuanjia Army, consisting of about 3,000 people, participated in it and played a major role.
Wang Shichong is not a Central Plains but a current Iranian, the style of fighting is very wild, somewhat similar to the Wei Wu pawns trained by Wu Qi in the Warring States Period, the Chengfang array team specializes in restraining cavalry, and is the Central Plains people do not have the tactics of restraining cavalry with infantry, almost winning every battle against the Tang army cavalry.
At this time, the role of the Xuanjia Army was revealed, the Xuanjia Army at that time belonged to the heavy army, just like the armor-piercing army of the Qin Dynasty, it was the main combat force of the infantry, and in the end, the three thousand Xuanjia army led by Li Shimin played a major role, and the Battle of Tiger Prison also achieved a major victory.
The second major war in which the Xuanjia Cangyun Army participated was a foreign war, also known as the Hengluo War. At that time, the Tang Dynasty had already fallen, and the Western Regions encountered foreign invasions. In the game, after Xue Zhi's death, the eldest son once again set up the Xuanjia Army, although it was in the name of Xue Zhi's revenge, but in fact they still took the protection of the Tang frontier as the main task.
The Strange Knife Team led by Sun Forgetful was the main force of the Xuanjia Cangyun Army at that time, and in real history, it was this Strange Knife Team that served as the main force in the Battle of Hengluo at that time. Although the war ended in defeat, the Arabs who fought against it also won a fierce victory, and from then on they did not dare to invade Datang again, and the Mo Dao team used their sacrifices to ensure Datang's absolute control over the Western Regions.
