Tian Khan, Restarting the Prosperous Kaiyuan Era

In the twenty-fourth year of Kaiyuan, in the dusk of the prosperous Tang Dynasty, undercurrents surged. The soul of Zhenguan suddenly appeared in the body of Tianbao. Li Shimin, the Heavenly Khan, woke up from a century-old sleep and turned out to be his great-grandson - Emperor Li Longji of the Tang Ming Dynasty, who was pushing the empire into the abyss step by step. Faced with the treacherous prime minister in the court, the arrogant heroes in the border towns, secret fights in the harem, and the Anshi Rebellion that was about to tear apart the prosperous age, Li Shimin pulled out the dusty sword. With his vision and iron-blooded skills that surpassed the times, he purged the government, revolutionized the military and politics, promoted various industries, and vowed to forge this prosperous and prosperous age into a steel empire that would never overturn. This time, he wanted to grab fate by the throat with his own hands. This time, Chang'an City, where all nations come to visit, will truly become the center of the world. This is an epic legend about an emperor who lasted through the ages and changed his destiny against the will of heaven at the end of his dynasty and restarted the prosperous age.
