The virus outbreak divides humanity into purifiers (awakening superpowers) and infected (evolved zombies). The protagonist Jiang Xun's awakened power is very special - he can "see" the death scenes of some people: who killed them, how they died, and where they died, for three seconds.
But this ability is a curse. He saw that the old man digging through the trash can would be bitten to death by zombies. After being reminded, the old man didn't believe it and died in front of him four minutes later, his eyes full of resentment - as if to say: Why didn't you stop me? From then on, Jiang Xun chose to remain silent, watching helplessly as the child chasing the butterfly was killed, and watched every life disappear before his eyes.
He meets Su Wan who is looking for her nephew and accompanies her on a journey through the ruins. On the road, I met the "Chinese teacher" who killed his zombie son to protect his family, the old mother who was waiting to die alone, A Huo who let him live, the mysterious old man who survived in the end... Every encounter is a mirror, reflecting the complexity of human nature in the apocalypse - some eat people, some save people, and some kill because of love.
Jiang Xun gradually understood: his ability is not to see death, but to see how long the living people will live. When he himself was dying, what he saw was that the people he protected - Su Wan, Yaya, Xiaohu, Zhou Xiaobao - were all alive and well in the sun.
Eventually he returned to the gathering place and sat on the roof looking at the living people in the courtyard. Zombies roared in the distance, and the moonlight shone on the ruins. He said softly: I saw it.
After seeing death, I also saw the meaning of living - not to save everyone, but to remember this moment, they are still together.
