I, Li Chen, Will Recreate the Prosperous Tang Dynasty

Li Chen, a college master's student studying the history of the Tang Dynasty, accidentally traveled through time and became the Emperor Xuanzong of the Tang Dynasty Li Chen with the same name. Just after traveling through time, we encountered the crisis of the Manna Change! I was full of regrets about the late Tang Dynasty, but now that I have traveled through time, I will endure the consequences, rewrite the decline of the late Tang Dynasty brought about by political troubles, party disputes, and vassal towns, and rebuild the prosperous Tang Dynasty!
