During the Taiyuan period, dust covered the sun in the north. The Xiongnu, Xianbei, Jie, Di, and Qiang tribes split the earth, and the Han people were like grass and mustard. In the puppet court supported by the remnants of the Zhao Dynasty, the emperor Li Chang looked at the eunuch Zuo Feng's face even for a bowl of porridge in the imperial kitchen. Hu Yanlie, a powerful official of the Jie clan, went to the palace to hold a sword and went down to the palace to seize concubines. The court was his horse farm. Li Yan thought he would be sent away with a glass of poisonous wine one day, until the "Tianfang Ancient Scroll" bound his soul - cleansing himself five times a day, signing in unshakably, and locking the system after three interruptions. After cleansing his hands for the first time, he summoned the first Gulam cavalry and crushed Hu Yanlie's personal guards with iron hoofs. After kneeling down for the second time, his destiny value skyrocketed. He activated the siege crossbow array and nailed the Jie tribe's 30,000 cavalry to the Zhangshui River beach. But the system is not omnipotent: if more than half of the summoned troops suffer casualties, they will have to be reorganized for thirty days, and if their destiny reaches zero, they will be eaten by the dead souls. As soon as Li Xi used a trick to lure the enemy to penetrate deeply and completely annihilate the left side of the Xiongnu, Hu Yanlie joined forces with Murong Chong of Xianbei to besiege the city, and Zuo Feng cut off his water source in the palace. What's worse is that the modern tactics in his mind were warned by the system - direct application will inevitably lead to backlash, and must be transformed into military manuals and equipment blueprints of this era. When the Five Hu Allied Forces raised the flag to massacre the city, Li Xi washed his hands and opened the seventh page of the Tianfang Ancient Scroll at the top of the city. This time, he summoned not cavalry, but the "Warriors of Faith" who once swept across Central Asia - each carrying gunpowder and compound bows.
