Cheng Yan travels through time, only to end up becoming an honorable prince in the Middle Ages of Europe. Yet this world was not quite as simple as he thought. Witches with magical powers abound, and fearsome wars between churches and kingdoms rage throughout the land. Roland, a prince regarded as hopeless by his own father and assigned to the worst fief, spends his time developing a poor and backward town into a strong and modern city, while fighting against his siblings for the throne and absolute control over the kingdom. Join Roland as he befriends and allies with witches and, through fighting and even farming, pushes back invaders from the realm of evil.
Roland spent all his time copying the textbooks after Tilly bid her farewell.
He first started with the basic courses. As he had just got a chance to revisit the knowledge long forgotten, naturally, he needed to take the advantage of it and add the missing information to the textbooks previously drafted based purely on his memory.
Second, he had to improve the designs of the current equipment used in the city of Neverwinter. Roland knew there was still a big difference between an acceptable machine and a good one. A more comprehensive design could further enhance the productivity and efficiency of steam engines and machine tools.
Based on the new design, Anna had finally completed the first steam turbine.
