Crossing HRE: Knight Lord to Continental Lord

In AD 1152, in the early days of the Holy Roman Empire of Frederick I, the princes were divided, bandits were rampant, and medical care was scarce. Reinhardt, a lover of modern history and military engineering, traveled through the world as a landless knight knight who lost his family after his father died and was on the verge of being deprived of his identity. In a desperate situation, he joined the chat group of all the worlds. Sun Wu taught tactics, Mozi taught crafts, and Sun Simiao taught medical skills. The group of friends helped to make progress step by step without direct dimensionality reduction attacks, which was in line with the steady implementation of medieval productivity. From wiping out bandits and acquiring the first fiefdom, to fighting for hegemony among the princes, ascending to the throne of the Holy Ra Emperor, and finally unifying the European continent, Reinhard used his landless body to draw on the wisdom of the gods to carve out a legendary path from a knight to the common master of the European continent in the Middle Ages.
