Transmigrator Pei Jingxing served as a county magistrate in the Tang Dynasty for ten years, governing the impoverished Yanling County into a prosperous land. The system, late by ten years, gives only one task: to be beheaded by Li Shimin in order to go home. He writes a life-urging memorial confessing to embezzling 800,000 guan, waiting to be punished. Unexpectedly, Li Shimin travels incognito, seeing thriving roads, bustling wards, and peaceful citizens, and becomes more and more appreciative the more he investigates. Merchant guilds collude with officials to seize his industry, and Li Shimin reveals his identity to save people, instead promoting him back to the capital. The system prompts that the return has failed.
