Modern emergency doctor Zhang Heng traveled to Weibo Town in the late Tang Dynasty and became a junior member of the Yajun. He is familiar with the trend of history - this "Silver Spear Army" that has been arrogant for hundreds of years will eventually be purged and killed, but it will be unable to break away from the torrent of the times. From the bloody night when Luo Shaowei borrowed Zhu Wen's help to massacre 8,000 tooth troops, to Yang Shihou's creation of a new army, to Li Cunxu's acquisition of Wei Bo's elite troops to destroy the Liang and Tang Dynasties, Zhang Heng personally experienced the core moments of regime change in the Five Dynasties. He used modern knowledge to improve military affairs, treat his comrades, and tried to preserve "human" things in the cracks of history. However, he saw that the arrogant soldiers were difficult to control and the fate of destruction was approaching step by step. Finally, on the eve of the Beizhou Massacre in 929, he made a decision: to use himself as a cover, to secretly dismiss hundreds of his trusted disciples, so that the seeds could quietly continue in the troubled times.
