In the third year after the cataclysm ripped apart the ozone layer, in the ruins of Rusty Iron City, sunlight was a luxury, radiation crystal cores were hard currency, and the roars of mutated creatures were more common than human voices. Scavenger Lin Ye clutched half of an old photo of his younger sister Lin Xi and lived among the ruins. In the disaster three years ago, he and his younger sister were separated in the crowd, leaving only the vague clue of "Red Star Elementary School".
While avoiding an attack by a shadow beast, he accidentally activated the artificial intelligence "Xingtian" mentioned by his father before his death: a cold mechanical voice hidden in a military terminal, which can analyze the weaknesses of mutated creatures and use radiation crystal nuclei to drive desperate counterattacks. But Xingtian's appearance not only brought hope of survival, but also revealed a more terrifying truth: the destruction of Safe Zone 7 was no accident. There was unknown energy controlling the shadow beast, and the name of his sister Lin Xi actually appeared in Xingtian's old encrypted data.
The radioactive crystal core in the iron box attracted swarms of mutants. The red alarm countdown in the depths of the tunnel kept beating. A strange man coughed up black blood and said the last words of "there is a ghost in the safe zone"... Lin Ye held the fire ax and listened to Xing Tian's combat suggestions. While surviving the fangs of rot rats and shadow beasts, he also wanted to find his sister in the doomsday information that was difficult to distinguish between true and false. He gradually discovered that the most terrifying thing in this apocalypse was not the mutated creatures, but the bottom line that humans had given up in order to survive; and the warmest thing was the smile of his sister in the photo, which supported him in refusing to stop in despair.
When the prompt "Lin Xi's life signal detected" popped up on Xing Tian's screen. . .
