My Father Is Fang La, and He Pushed the Song Dynasty by Adding Some Points.

During the Xuanhe period, the royal family was fatuous, six thieves were in power, and the disgrace of Jingkang was imminent. Fang Xuan woke up and became Fang La's eldest son. He didn't want his whole family to die tragically, so he could only raise the banner and fight against it. Bind the plunder system and kill enemies to reveal blueprints and entries. As a result, Fang Xuan began the road of detonating troops without being a human being. Use artillery to smash Tong Guan's 100,000-strong army, and use the tactic of lining up and shooting to defeat Guan Sheng's chain of horses. He intercepted Hu Yuefei, subdued Han Shizhong, and established a steel army that swept the world. When Wanyan Aguda led the invincible Jin cavalry south, what he saw was a dense artillery emplacement. Fang Xuan is sitting in Bianjing, overlooking the world. This great river and mountain will be guarded by me, Fang Xuan!
