Back in the Tang Dynasty as the Emperor's Grandson

After transmigrating to the late Kaiyuan era of the Tang Dynasty, I found the emperor neglecting state affairs, corrupt ministers in power, and war raging on the frontiers. As the emperor’s eldest legitimate grandson, I had to step forward. I’ll take on Li Longji, battle Li Linfu, punish Yang Guifei, kill Yang Guozhong, take down An Lushan, and prevent the An Lushan Rebellion before it begins. I’ll make sure the golden age of the Tang Dynasty never ends. Wherever the sun and moon shine, wherever the wind and rain reach, all will be Tang territory!
