Deposed crown prince's illegitimate daughter Xiao Wei is plotted against and thrown into a well, souls-crossed by modern military history science blogger Lin Zhixia, accidentally binding with the Monarch Assisting System. Leaving the palace under the alias Lin Zhao, she relies on wits to step by step reach the pinnacle of power. She travels far to the border frontier to offer strategies to repel enemies, improve military rations, rescue soldiers and generals, relying on true skills to stabilize the northern defense line; returning to the capital she outwits corrupt chancellor Gu Chengzhang, rips open the corruption chain via the old canal transport case, and even sees through crown prince Xiao Jing colluding with Northern Di and poisoning the sovereign father to usurp the throne. From a cold palace abandoned daughter to a court newcomer, from having grievances redressed to ascending to rule the realm, Xiao Wei plans step by step, finally ascending the imperial throne, soon to hold hands with the system to create a brand-new prosperous era belonging to Great Liang.
