[Technology + political intrigue + layout + hegemony, no system, slow pace, please don’t criticize if you don’t like it] In 1868, Milan, a time traveler who had been hiding for more than ten years, had just finished reaping a wave of profits in Europe when his cousin was stabbed and he became the Grand Duke of Serbia.

How can a time traveler be content with a small principality? Alexander's imperial glory, the splendor of Eastern Rome! Southern Europe is still waiting for revival!

But the Serbs are too small, and Pan-Yugoslavia is not grand enough. We might as well just mix all the peoples in the Balkans and the lower reaches of the Danube into one pot, and Latin Slavia will be good...

This is a story about the struggle for hegemony in modern Europe, how a small country became a great power and eventually grew into the third pole.
