Medieval Times: I Dominate the Continent by Sheltering Witches

Middle Ages+Fantasy+Witch+HRE This is a fantasy world of the Middle Ages, starting with the Holy Roman Empire in 1076. The nobles considered witches extremely dangerous and avoided them one after another. They even used witches as suicide weapons to destroy their enemies. But Leo selflessly took them in, allowing them to live well, and at the same time, he also gained their allegiance. "Ding! The host can not only accommodate witches, but also female elves, giant dragon ladies, and even queens." The system says so. Decades later, when the cavalry regiment equipped with artillery and short guns confidently invaded the continent of Europa again, they were surprised to find a man with black hair and black eyes standing in front of the grassland cavalry all over the mountains and plains—— "Cooperate, or... Die." Snap, Leo snapped his fingers, and hundreds of magic mechas that could only be piloted by witches came to the world from the containment space and slowly emerged in the void.
