Three years ago, S-class agent Song Hanjiang was betrayed by his teammates during his last mission and watched his wife die in front of him. He retired with his infant daughter in his arms, changed his name to Song Ye, lived in the old town of Jiangcheng, and became a single father who opened a noodle shop.
No one knows that this silent man who gets up at four in the morning to knead dough and braid his daughter's hair was once the country's sharpest knife. No one knows that his daughter Song Zhiyi has shown an amazing ability since she was two years old - she can "see" the time and space marks left on objects.
When a strange woman brought a pocket watch that smelled of blood to the noodle shop, Song Zhiyi pointed at the pocket watch and said, "Dad, this uncle hurts so much."
Song Ye's peaceful life was completely torn apart. He found himself trapped in a space-time mystery that spanned thirty years: the death of his wife, the betrayal of the organization, the space-time experiment that disappeared ten years ago, and the awakening superpowers of his daughter, all connected by an invisible thread.
In order to protect her daughter, Song Ye overturned the table and picked up the gun again. But this time, his opponent is not humans, but... Time itself.
