Lin Mo, a history student at Jiangcheng University, was researching the fifth year of Ganlu in depth for his graduation thesis on the collapse of imperial authority in the late Cao Wei period. But after an accidental electric shock, he transmigrated into Cao Mao, the puppet emperor who was to be assassinated the very next day by one of Sima Zhao's trusted men. Trapped in a desperate situation, with history's deadline closing in and the powerful minister Sima Zhao commanding the court and controlling a network of loyalists, the palace guards were old and weak, and Cao Mao had few allies. Everywhere he looked, he saw a dead end.
With a thousand years of historical perspective and modern wisdom, Lin Mo knew all too well the tragedy of Cao Mao's suicidal attempt to strike down the traitors, and understood the fate awaiting the Cao Wei imperial clan. Suppressing his fear, he resolved to rewrite his destiny: first, he would feign weakness to keep Sima Zhao at ease, then use a traitor to spread false information and buy himself some breathing room. Next, he would recognize talent and win over the utterly loyal Wang Jing as his right-hand man, laying a solid foundation. Then he would secretly make plans, using the stirrup, a revolutionary tool for the age, as his starting point to train an elite force of ironclad cavalry and build up the strength to turn the tables.
From waking in terror in the Ganlu Hall to secretly maneuvering against Sima Zhao's faction, from perilous tests to distinguish loyalists from traitors to carefully building a powerful army, the once-puppet emperor would ultimately use strategies and courage beyond his time to topple the Sima clan's overwhelming power and restore Wei's former glory. Amid the chaos of the late Three Kingdoms, he would forge a path to his own destiny.
