Jiang Shuai, the ancestor of zombies, has lived for thousands of years and is tired of eternal life. He made an agreement with the human race, never to bite anyone to pass on his descendants, and to walk alone in the dark.
Su Xiaoyu, an ordinary female college student, is sunny and kind-hearted, but she is destined to commit a sinister crime and will not live to be 25 years old. Her life creed is: since life is short, live to the fullest every day.
In an accident, Jiang Shuai was exposed to the sun to save Su Xiaoyu and was on the verge of annihilation. Su Xiaoyu didn't know which tendon was wrong, so she cut her wrist and fed blood, saving this thousand-year-old zombie.
After waking up, Jiang Shuai found that not only was he not dead, but because of Su Xiaoyu's inexplicable tears, he could walk under the sun again, and even... His heartbeat began to recover?
What's even worse is that the entire underground world and mysterious organizations have gone crazy - according to legend, the human blood that can "resurrect" the ancestor of zombies is the key to the "eternal kingdom".
On one side is a useless female man who just wants to live beyond the age of 25, and on the other side is a thousand-year-old zombie who can't die even if he wants to. Villains from all walks of life swarmed in, some wanted her blood, some wanted his life.
Facing a life and death crisis, Jiang Shuai crossed his arms and asked Amelia Su: "Are you afraid?"
Amelia Su rolled her eyes: "I'm afraid of ghosts! Anyway, I won't live long, and I can take a thousand-year-old zombie as my little brother before I die. I'm sure to make a profit!"
In this whirlpool that concerns the survival of the two worlds, Jiang Shuai finds that he is not only protecting this girl, but also his heart, which has been lost for thousands of years.
