Release That Witch
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.
A Different Story
Editor: Meh
After a busy week, Roland built a new chemical factory next to the Redwater River. Considering the toxicity of nitrogen oxide, this factory was built like the Convenience Market, with a gaping wall and wooden roof, a one-story tall gap in the middle, and awful ventilation. Of course, the temperature inside was pretty much the same with that outside.
The new oxygen and nitrogen synthesizing system was already in use. The heat produced instantaneously by the Blackfire was the same as an electric arc and was much more efficient. After the raw materials were placed into the reactor, Anna only needed 8 minutes to turn them into nitrogen dioxide, which produced nitric acid when combined with water.
