Xing Yuntao, a top student in the history department, traveled to Chang'an in the third year of Zhenguan because of a jade dragon pendant from the Tang Dynasty. The "Zhenguan Heavenly Way Correction System" bound in his mind became his trump card for survival. System tasks follow one after another: gain the trust of the old men of the Qin Palace within 72 hours, solve the mystery of the monster rebellion in Chang'an, and even use historical knowledge to correct the undercurrent of the government without triggering a backlash from heaven.
This Tang Dynasty is far more fantastic than the history books: Hu merchants in the Western City hide the true identity of the camel demon, court officials and sorcerers have formed an alliance, and Li Shimin's destiny as "Khan of Heaven" is being eroded by the power of chaos. Xing Yuntao holds the "Zi Zhi Tong Jian" in his left hand to predict the crisis, and uses modern wisdom to rectify the government and improve people's livelihood; holding the spell array in his right hand, he joins forces with the upright Taoist Li Qingxuan to hunt down the Shadow Evil and fight against the Demon Emperor.
He gradually understood that the "right of correction" granted by the system was never a tool to subvert history, but a responsibility to protect the prosperous age. When modern rationality collides with ancient fantasy, when system rules meet the fireworks of the world, let's see how the time-traveling academic master works step by step in the storm of Zhenguan and writes his own legend of the Tang Dynasty.
