This is the story of a divine general and a princess of the Immortal Realm.
Legend has it that beneath the lotus throne of the Celestial Emperor and Empress sat a fairy known as the Third Princess, belonging to the Immortal Realm of the Myriad Heavens of Huaxia. When the armies of evil spirits from the Nine Hells invaded, the Third Princess had no choice but to seal the Great Evil God to protect the immortal clans of the Myriad Heavens. In doing so, however, she fell into a 7,000-year slumber and lost her memories.
Seven thousand years later, a young man named Yin Xiaoshuai appeared.
Yin Xiaoshuai was a down-and-out man who had been unexpectedly dumped by his ex-girlfriend, Zhang Liqiao. By chance, he was promoted by the divine general Chen Kai and became the Eagle Dragon, a Han general of the Palace Guard. In the human world, he made many good friends who were into historical costumes, as well as all kinds of people with extraordinary abilities. Under Chen Kai's direction, Yin Xiaoshuai overcame one obstacle after another and helped the Third Princess, Yanyan, awaken and recover her memories. He escorted Yanyan back to the Heavenly Realm. From then on, Yin Xiaoshuai embarked on the path of cultivating immortality.
