In the third century BC, the alchemist Xiao Le discovered the art of immortality and his appearance remained forever, but he saw the dynasty change and his best friends disappear. Frustrated, he fell asleep deep in Zhongnan Mountain, sealing his immortal body into a pottery figurine, hoping that time would forget it.
In 2025 AD, when Xiaotang, an archeology student, was interning in a museum, blood accidentally dripped from his fingertips, which unexpectedly awakened the thousand-year seal. Wearing deep clothes and wide sleeves, he stepped into a strange world with flashing neon lights and flowing information. Mobile phones, the Internet, skyscrapers... The former world's best in cultivation is at a loss in a modern city with different rules; and the wisdom and loneliness accumulated over two thousand years have nowhere to put it.
Xiaotang's ordinary life was completely overturned by this "ancient man who descended from heaven". From taking him in out of fear to helping him learn to integrate, she gradually discovered that deep in his indifferent eyes not only hidden the bright moon of the Qin Dynasty and the fireworks of the prosperous Tang Dynasty, but also involved an ancient secret buried in the dust of history. When the secret organization smells something abnormal, and when the dormant past grudges quietly awaken, a protection and choice spanning time and space begins.
This is a story about how the Eternals learn to be "human" again, and also a story about how an ordinary person illuminates a thousand years of loneliness. When the oldest immortal meets the most vivid present, should they renew their relationship or write a new legend?
