A dream of clouds and smoke, everything is just the expectation of the heart. Furong arrived in the Tang Dynasty in her sleep and became Chai Xu, the daughter of Chai Shao. As the daughter of the princess who protects the country and the richest man in the Tang Dynasty, she plays the world. Smiling at the mortal world, singing and dancing to peace. There she was no longer Fu Rong, who couldn't breathe due to the pressure of work, nor Chai Xu, who was helpless in the vortex of power. She was just her, Ling Yan, playing in the world. But the dream will eventually wake up.
