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.
Four days later, a firing room was built in the backyard at North Slope Mine.
Two deep holes were dug in the yard, each one was round, with a narrow top and a wide bottom. The front diameter was about 20 centimeters, while the rear end was enlarged to 26 centimeters. Roland intended to use these holes to cast the mold. The hole had already been baked by Anna, and the surface of the soil was sintered into a whole like an outer shell. The chamber faced downwards so that a better wall quality could be achieved during casting. If the chamber were placed higher, more dross and bubbles would be produced. All the cave sizes were calculated by shells as he vaguely remembered that the so-called six-pound and eight-pound cannon were named according to the weight of their shells. So a few 12-pound iron balls were poured out, and the ball diameter plus barrel wall thickness were used to calculate the mold diameter.
