Banished to the Frontier, I Slaughtered My Way Across the Continent

I transmigrated from the start, only to fall victim to a honey trap and get banished to the frontier to fend for myself. The emperor wants to keep me under control, and the princes want to assassinate me. They have no idea that my modern knowledge gives me an overwhelming advantage over them. Prince, this border town belongs to several of my great families. If you’re a dragon, you’d better coil up. If you’re a tiger, you’d better lie low. Oh, really? Then I’ll simply steamroll you all. The frontier tribes are at war with one another, and now they’re asking me for help? Your territories are too small. Fighting each other is pointless. I’ll show you what a unified empire looks like. The island navy is getting too brazen. Then I’ll build ships and wipe them all out, adding their territory to my domain. My lord, we haven’t expanded our territory in three months. The soldiers are all eager to distinguish themselves and build careers... When the emperor saw how powerful I’d become and tried to take back my territory, he realized it was already too late. By the time I led a million troops to surround the imperial capital, it was too late for the emperor to regret it...
