Who Put the Imperial Robe on Me When All I Had Was Congee and Pickles?

[Historical what-if, alternate history, historical, play the pig to eat the tiger, scheming, System, transmigrate, doting on his younger sister] Lin Mo wakes up in the ancient feudal dynasty of Great Qian, having transmigrated into the county magistrate of Wuning County, a border region of Youzhou. From the start, he gets a Shop System, an unlimited supply of rice and copper cash, and begins governing the county. With just 10 soldiers recruited, even the local bandits can bully him with impunity. With 100 soldiers, the bandits have to think twice before attacking the city. With 1,000 soldiers, he still dares to order the local prefect around. With 10,000 soldiers, the prefect respectfully addresses him as Lord Lin. With 100,000 soldiers, the emperor sends an order. Do you dare challenge the court? Are you trying to rebel? With 1,000,000 soldiers... You foolish emperor, I hear my long-lost younger sister became a palace maiden, entered the palace, and even became your consort? My clever and lovely nephew has made the empress jealous. The empress plotted to eliminate my sister and nephew, and they’re to be executed this autumn? I order you to execute the empress and crown prince at once, make my sister empress, and name my nephew crown prince. What? You say the empress is backed by the Seven Great Clans? Soldiers, heed my command!!!! When autumn comes, on the eighth day of the ninth month, my flowers bloom and all others die. Their fragrance fills Chang’an, and golden armor gleams across the city. All I did was make sure there was enough rice and copper cash. Who put these imperial robes on me?
