To be Prince of Europe

This is medieval Europe, yet not the real Europe. Because here, in addition to everything original from medieval Europe, there inexplicably exist mages, demihumans, monsters, and all sorts of dangerous and powerful creatures. Damian, who reincarnated here by accident, how will he survive in this strange European continent full of magical colors? "Don't worry, everything will be fine," Damian smiled after looking at the war system interface in front of him. "If it's just about surviving here, there shouldn't be a problem." The adventurous courage and passion, the blood and fire of war, the intrigues and power struggles of the court. Defeating dangerous enemies, gaining reliable allies, upgrading one's own system abilities, cultivating a powerful army unique to oneself, encountering various charming women, and finally——standing at the top of Europe amidst the adoration of the masses. In fact, he originally just wanted to survive on this medieval European continent. But unknowingly... power, wealth, authority, women, everything silently fell into his hands, until he became the prince of the entire Europe. "So, who exactly is spreading rumors that I became the prince by relying on my lower half??"
