In a mysterious ancient house "Tingxue Tower" hidden deep in the Wulan Mountains, cultural relic restorer Su Xiaotang accidentally triggered the time resonance of the old house, and together with Lin Chenyu, a historical researcher who came to sort out ancient books, he was involved in a whirlpool of secrets that spanned a century. When dusty cultural relics whisper in the middle of the night, and when yellowed ancient books emerge with dynamic images, two young people with very different personalities are forced to form a "bomb disposal team" to solve layers of mysteries in the process of restoring cultural relics. From bronze chimes that play lost music to carved bronze mirrors that reflect images of past lives, every cultural relic is a key to history, and the ultimate secret hidden deep in the ancient house is quietly rewriting their fate.
