In the 21st century, the little demon king Xu Youyou accidentally fell from the rockery and was transmigrated into the little princess of Hades Palace. With her naturally naughty temperament, she made a big fuss in the underworld, tormenting ghosts and provoking Pluto's father, but she was also favored by Pluto and his wife and the Xuan Shen Tian Zun in the upper realm. As she grew up, she lost her childishness and became stunningly beautiful. In the game between the underworld and the heaven, she developed a meticulous and sinister mind - she turned against Yao Ji at the peach banquet, and easily resolved the trap in the heaven, fully demonstrating the characteristics of "coexistence of appearance and scheming".
Just as she was establishing a foothold in the heaven, she unexpectedly returned to a modern hospital due to the activation of her soul mark. With the memories of two lives and the remaining spiritual power, she quickly adapted to life in the mortal world, using shady methods to deal with school bullies and troublesome relatives, while secretly exploring a way to return to the Three Realms. From the mysterious ancient jade in the ancient temple on the outskirts of the city to the jade talisman mark given by Ming Yuan on the wrist, the clues are gradually intertwined, and a larger storm spanning modern times and the Three Realms is quietly brewing.
