I Transmigrated, and I Must Stop the An Lushan Rebellion

Li Mingyuan, a modern graduate student in history, transmigrates by accident to the Tianbao era of Emperor Xuanzong's reign in the Tang dynasty, where he becomes an ordinary border guard in a small frontier town. On the brink of death, he activates the Golden Age Simulation System. It can predict how history will unfold based on his actions, and unlock modern technology blueprints and management expertise. Knowing that the An Lushan Rebellion will slash China's population by thirty million and send the once-great Tang dynasty into decline, Li Mingyuan makes it his life's mission to stop the rebellion and build an even greater Tang.

Drawing on his precise knowledge of key historical events, he first foils a plot by a small Turkic force at the border, earning the military's initial trust. He then uses the System to obtain plans for the curved-shaft plow, sparking an agricultural revolution in Guanzhong and attracting the attention of Chancellor Zhang Jiuling. But as his standing rises, he becomes entangled in the struggle between imperial power and the regional military governors. He must contend with An Lushan's probes and attempts to win him over, defuse the suspicions of Yang Guifei and her brother, and find his footing amid Li Longji's shifting bouts of clear-mindedness and senility in his later years.

Along the way, he befriends the upright frontier general Guo Ziyi and Su Wan'er, a mysterious businesswoman with a network of informants in Chang'an. But he also makes enemies of the ambitious Shi Siming and the treacherous Li Linfu. When the System warns that the probability of the An Lushan Rebellion breaking out has risen to 70%, Li Mingyuan realizes that simply stopping the rebellion is not enough. He must completely rebuild the Tang dynasty's power structure and foundations of public welfare. A transformation combining modern management principles with the wisdom of ancient political intrigue is about to unfold in the Tang dynasty, with a storm on the horizon.
