Travel to the Later Zhou Dynasty to Save Zhou Shizong

The protagonist Li Yun traveled to the era of post-Zhou Chai Rong, relied on a little nursing knowledge to save Zhou Shizong, who was about to die, and witnessed the feat of this fifth-generation hero to regain Yan Yun. Li Yun, who was deeply trusted by Chai Rong, also further helped his master reform the army system of the Later Zhou Dynasty, abandoning the harmful Northern Song Dynasty system that emphasized civility over military force, and instead established an army for the Later Zhou Dynasty that was based on the old Han and Tang Dynasty systems with a small standing army and a large number of conscripts.
