At Dayao Kingdom's Hundred Flowers Festival, Shen Yuxuan, the descendant of the Jiangnan music family, was valued by the Crown Princess Nangong Liuli and the master of Fengyue Tower, Jun Zhanyu. The middle palace prince Feng Xuanyue had a nightmare. He played the flute in his dream to find allies, hoping to break the predicament and wake up to save Nanyue from domestic and foreign troubles. Shen Yuxuan unintentionally broke into the prince's dream, and entered the soul of the prince Feng Xuanyue with the song "Mountains and Flowing Water". He and her played the piano and the harp, and she unexpectedly fell in love with the prince who was deeply in the dream. Just because the two of them had the same mind, she understood what he meant, and he understood what she meant in the song. The two regarded each other as bosom friends. Shen Yuxuan is willing to help Prince Feng Xuanyue win the world, but only after Prince Feng Xuanyue wakes up from her dream can the situation of Dayao Kingdom be stabilized. When the imperial doctor was struggling to find a good solution, the world had changed, and the Sixth Prince Feng Xuanyu was sitting in the middle palace. There are rumors in the world that the one who can win the Requiem will win the world, and "The Requiem" is a small poem on the title page of a mysterious ancient song from the south of the Yangtze River. Whoever can decipher this poem will win the Tiger Tiger Talisman. In the secret passage of the palace laid out by Jun Zhanyu, Shen Yuxuan cracked the palace, won the "Quiet" and solved the mystery of his life experience. The prince woke up from his dream, and Shen Yuxuan, who had discovered the truth about his life experience, returned to Nanyue Kingdom. From then on, the two were separated forever.
