You Are the Emperor, I Am the True Dragon

The last true dragon, Xiao Longyuan, built the Dragon Temple to protect the world for five hundred years. After Empress Murong Zhaohua ascended the throne, she feared his achievements, demoted him to a commoner, destroyed the temple, and summoned demons, causing chaos and rebellion. Prime Minister Li Si colluded with demons to control the court and planned to kill Xiao Longyuan. Forced to fight a nation alone, Xiao Longyuan rebuilt the world with his former maid, Qin Li. Murong Zhaohua, now a commoner after her country fell, used herself to lure the demons and joined forces with Xiao Longyuan to destroy them and restore peace. Xiao Longyuan then left the mortal world and no longer interfered in human affairs.
