She is an immortal person who has lived for thousands of years.
From the deification of gods in the Shang and Zhou Dynasties to the changes in the Ming and Qing Dynasties, she helped the princes to regulate the world, and also hid in the market to watch the vicissitudes of life. During the turmoil at the end of the Ming Dynasty, she slept for 300 years. When she woke up, it was the chaotic times of the Republic of China. She took a down-and-out scholar Zhou Qingyan as her servant to protect his family's prosperity for hundreds of years.
Before Zhou Qingyan died, he entrusted her granddaughter Zhou Xingran, who was born with "yin and yang eyes", to her. "Miss Hu Miao, protect her and protect this world."
As a result, the immortal who had lived for too long and was indifferent to worldly affairs was surrounded by a modern girl who was astonishing. One uses ancient magic formations to transcend demons, the other relies on mobile phones to check information and drones to chase ghosts. While the master-servant duo solves bizarre incidents in the bizarre city, they also gradually come into contact with the shocking secret that put her to sleep 300 years ago - an immortal with the same origin as her covets her power of immortality and wants to break the balance between the human and spiritual worlds.
When an ancient contract meets modern thinking, when the dusty past collides with an immediate crisis, Hu Miao looks at the noisy Chen Nian beside her and feels for the first time that this long and boring life seems to have a "now" worth guarding.
History is her footnote, the world is her battlefield, and this time, she is no longer alone
