Total War: Byzantium in the Middle Ages

Qin Ming was an ordinary university student in modern times who loved the Total War game series. By a strange twist of fate, he accidentally transmigrated to another world existing in the same era as Blue Star. It was now the twelfth century, and the Byzantine Empire was plagued by powerful regional warlords carving up its territory and greedy nobles throughout society. To the east and south were numerous fanatical and powerful non-Christian states. To the west were the Roman Curia, which had fallen out with the empire, and states founded after barbarian invasions. To the north were nomadic peoples and the warlike Rus. Byzantium no longer deserved the great name of empire. Watch as the protagonist, after transmigrating, relies on his System to gradually restore the declining empire to greatness.
