Tang Yin: Hua Ci Meng

Gu Yan graduated from the Department of History + Acoustic Physics with a double major. He is the best among top academics. Traveling back to the prosperous age of Kaiyuan, he discovered that his knowledge was the biggest golden finger - not copying poems or memorizing lyrics, but using acoustic principles to improve musical instruments, using spectrum analysis to adjust the melody, and using resonant frequencies to decipher the mysteries of cultural relics. A Tang Dynasty Lushan kiln flower porcelain waist drum, a drum sound of 83 Hz, involved him in an unsolved case twenty years ago. The missing musician Shen Huaiyuan left behind a mysterious inscription: "This drum hides its sound, and its sound is in the sky. Anyone who hears it can see the true face of Kaiyuan." The undercurrent of Taichang Temple, the power struggle, and the attention of the palace people - Gu Yan uses knowledge to break the situation, uses music to gain a foothold, and uses acoustics to uncover the truth of the prosperous Tang Dynasty. A top student travels through time, does not copy poems, does not memorize lyrics, and uses scientific dimensionality reduction to attack.
