They've Reached Chang'an, and You Still Call Them Mere Soldiers?

I transmigrate into an alternate history and become a government soldier in Shazhou. I only wanted to live an honest, quiet life, but my relatives try to take everything from me because I have no heirs. My relatives want me dead. The local hooligans and dandies want me dead. The Tubo bandits to the south hate me to the core, too. The heroes of the land are no different. Zhao Mang is panicking, though not entirely. If none of them will let him live in peace, then he'll flip the table and be done with it. Starting as a common soldier and using Shazhou as his base, he charges ahead without restraint, from Shazhou to Lanzhou, from the local government to the imperial court, and from the borderlands to Lingnan, leaving behind a fearsome reputation. By the time everyone realizes what's happening, he has countless renowned generals among his followers, commands a million troops, and has declared himself king.
