Records of Immortality in Imperial Tombs

The Great Chu Empire, during the Tianqi period. The third prince, Xiao Chengxuan, fell out of favor with his mother and concubine and was framed for treason. At the age of eighteen, he was deprived of his status as a prince and sent to the most desolate "Yong'an Imperial Mausoleum" in the empire to keep vigil. Everyone thought that he would die alone in this place of death and become a loser with only a few strokes in the history books. Deep in the imperial mausoleum, there were only an old eunuch Zhou De'an and a demoted palace maid Shen Hengwu accompanying him. Weeding weeds, sweeping graves, burning incense and keeping vigil every day, day after day, like a living dead. However, while Xiao Chengxuan was cleaning the underground palace of the imperial mausoleum, he unexpectedly came across a secret that his ancestors had buried for thousands of years - a jade biscuit with the "Eternal Immortality Secret" engraved with ancient seals turned out to be a cultivation method left by an ancient immortal. From then on, during the day, he was an unknown prince in the eyes of the world, but at night, he practiced supreme immortality in the depths of the underground palace. Thirty years have passed, and the mortal emperor has grown old, but he is still as young as twenty years old. Sixty years have passed and the court has changed several times, but his appearance has not changed at all. A hundred years later, he was already a great monk in the Nascent Soul stage. Zhou De'an and Shen Hengwu around him also began to practice under his guidance. Although they were not as talented as him, they also embarked on the road to immortality. Around the imperial mausoleum, he subdued several spiritual beasts by chance - an injured white fox strayed into the imperial mausoleum and was transformed into a spirit after being treated by him; an old dragon suppressed in the dragon's veins recognized him as his master; and a crane that flew from Cangwu Mountain became his mount. Whenever the empire encounters a crisis - barbarian invasion, evil and evil, struggle for the throne, natural disaster, this "living god in the cold palace" will quietly take action.
