In the third century BC, the alchemist Xiao Le discovered the secret of immortality. His appearance remained unchanged, yet he lived to see dynasties rise and fall and dear friends pass away. Disillusioned, he fell into a deep sleep in the heart of Mount Zhongnan, sealing his undying body inside a terracotta figurine and hoping time would erase him from memory.
In 2025, Xiao Tang, an archaeology student interning at a museum, accidentally awakened the millennia-old seal when a drop of blood from her fingertip fell upon it. Clad in a wide-sleeved robe, he stepped into a strange world of neon lights and rushing streams of information. Phones, the internet, skyscrapers... The cultivation that had once made him the greatest under heaven was out of place in a modern city with entirely different rules, and he had nowhere to put the wisdom and loneliness accumulated over two thousand years.
Xiao Tang’s ordinary life was completely upended by this “man from the past.” After taking him in in a panic and helping him learn to fit in, she gradually discovered that behind his calm gaze lay not only the moonlit nights of The Legend of Qin and the vibrant splendor of the Tang Dynasty, but also an ancient secret buried beneath the dust of history. When a secret organization caught a scent of something unusual and the grudges of a sleeping past quietly stirred, a story of protection and choices spanning time began to unfold.
This is a story about how an immortal learns to be “human” again, and how an ordinary person illuminates a thousand years of solitude. When the oldest immortal meets the most vibrant present, will they rekindle an old bond or write a whole new legend?
