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.
Meanwhile, Lightning, Wendy, Maggie and Hummingbird were executing the final attack before the main offensive.
Because the main artillery of the battleships only fired solid bullets, they were largely ineffective against the personnel and defense facilities on the city wall. Hence, the witches aimed to destroy the first line of defense so as to puncture the enemy's effective strength and open up a safe channel for the general offensive.
This was also the first time that the hydrogen balloon was used in battle.
Unlike the thousand-mile raid five months back, the balloon lifted off from just beside the canal this time, allowing almost everyone to witness the ascent of this colossal object. Under Roland's plan, the hydrogen balloon, which could move anywhere without hindrance, was advanced enough to be used as a short-distance bomber during this era. With the fleet behind it providing logistical support, this earmarked the beginning of the generation of aircraft carrier combat.
