It's called "Phantom Sound Treasure Box"

In addition, the episode in the third part of Qin Shi Mingyue is even better! I recommend the following songs: (I am a loyal Qin fan) They are all available online

Interludes of "The Hundred Schools of Thought":

"The Storm Rises Again", "Across the World" "The Dust of the Troubled World" "Both Sides of the Yishui" "Dark Lights" "The Rhythm of the Piano and the Lotus Heart" "The Sound of the Piano in the Clear Night" "Flying Snow and Jade Flowers" "The Beauty and Fragrance of the Country" "A Dance to Allure the City"

"The Yishui" "Both Strait" The background music of the snow girl dressing up for the performance at the beginning of the animation

"Lights Dimming" The nobles entering the "Feixue Pavilion", which is the music when the two servants start the conversation

"The Rhythm of the Piano and the Lotus Heart" Before the appearance of the Snow Girl, Xiao Gao plays the piano and is accompanied by a bell (the biggest attraction here is the nasturtiums and lotus flowers emerging from the water. I have to sigh again at the prosperity of the Snow Girl's performance and the luxury of the ancients... )

"Flying Snow and Jade Flowers" Haha, this is my favorite, the flute song where the Snow Girl makes fun

"National Beauty and Heavenly Fragrance" Our sister, the Snow Girl, is gorgeous Appearance~~ (In fact, it should be regarded as the continuation of the accompaniment version of Flying Snow and Jade Flower...)

"A Dance to Allure the City" After the petals fly, the snow girl starts to dance ~ Let me add: Many people This dance is clearly a ballet. After all, jumping high, raising the leg and then crossing the leg are traditional movements of ballet, especially the one-leg rotation near the back... In fact, this is a kind of "tiptoeing" dance. That is, dancing on tiptoes. Ballet existed in China more than 2,000 years ago, and Handan in the State of Zhao was its birthplace.

"Qingye Qin Xing" The evil Lord Yan Chun gave wine to the snow girl and played the piano music before and after Xiao Gao
