I Was a Lord in the Middle Ages

Under the gloomy sky, executioners could be seen everywhere. The cruel Middle Ages, accompanied by famine and plague, made people miserable. Roger was born into a ducal family and was exiled by the family at the beginning. Coming to the distant White Horse Plains, the lord started his daily life. Obtaining sweet potato seedlings solved the famine problem, and invented penicillin to combat plague infections. Just when Roger was planning to develop his territory. I really discovered how unusual this world is. Mysterious powers, strange sequences, and unusual pathways. Roger, a lord favored by death, is about to open a new chapter in the world.
