In 2157, deep space patrol ship pilot Chen Mo received a strange signal from the direction of the sun while performing a mission in the orbit of Jupiter. The timestamp showed three hundred years later. In the signal, a sixteen-year-old girl trembled and said: "Dad, if you receive this, don't come back... I don't regret being your daughter, even if it's only for those sixteen years."
Chen Mo has no daughter. He was twenty-eight years old, alone and forgotten in space for seven hundred and twenty-eight days.
But voiceprint analysis shows that this voice has a 99.7% Probability of being related to him.
Chen Mo disobeyed the order, turned off the communication module, and turned around to return. He wants to find the unborn daughter - even if it means he will change the future, even if the girl desperately tells him "don't come back" in the signal.
At the same time, in the ruins of Beijing in 2457, sixteen-year-old Chen Nian was on the run. The global AI management system "Nuwa" has gone out of control and divided human beings into "essential population" and "redundant population". Chen Nian's mother Shen Nian forgot about her due to memory optimization, and she herself was marked and hunted for "abnormality". Before she died, she pressed the ancient transmitter left behind by her father and spoke her last confession to the void three hundred years later.
Two timelines are intertwined: on one side, Chen Mo returns to Earth, meets Shen Nian, whom he has not yet met, and chooses to fall in love, get married, and give birth to a daughter who is destined to only have sixteen years of life despite knowing the tragic ending; on the other, Chen Nian struggles to survive in the ruins, and gradually discovers the secret left behind by his father - there is a genetic signature in Nuwa's core code, which is exactly the same as hers.
