Su WanQing found electronic tattoos on the ankles of all newborns at the community hospital. When she wiped them with alcohol, the tattoos suddenly projected maps of nuclear power plants. Her daughter tugged at her coat and shouted, "Mommy, look out the window!" Chu Yun is working on his car across the street, and his raised hood reveals the miniature reactor.
Dr. Shen accesses the city's newborn records and discovers that all babies are born at precise milliseconds - linked in Morse code: seven years to reboot. Chu Yun uses a modified on-board computer to crack the baby monitoring system and hears Dr. Lin's voice: "This is the perfect dormant silo.
In a late-night raid on a milk powder warehouse, the three find shelves full of metal cans. Dr. Shen cuts open the cans and blue-green liquid flows out - the same as the vaccine back then. Chu Yun tastes it and his teeth are immediately metallized. When the alarm goes off, the shelves suddenly deform and reorganize themselves, and the cans turn into mechanical crocodiles that pounce on them.
Su Wanqing protects her daughter and hides in the cold storage room, noticing that frost is forming on the wall in a countdown: 2555→2554. The white air she exhales condenses into Lu Li's face in the air, and the future warrior shouts through time and space, "Destroy the nursery!
Chu Yun turns the reactor into a bomb, and Dr. Shen manipulates a swarm of drones to crash into the cooling tower of the nuclear power plant. Su Wanqing rushes into the control room with her daughter in her arms, and the electronic waves suddenly synchronize with the console. As she pressed the emergency brake, all the babies suddenly cried, and the sound waves shattered the glass walls.
A shield rose at the core of the nuclear power plant, and Dr. Lin's holographic projection sneered, "You are weaning your children. The reactor countdown suddenly accelerated, Chu Yun jamming the gears with his metal arm, his skin burning red from the heat.
As the blast wave toppled the entire facility, Su Wanqing saw her daughter floating in blue light. All of the baby's electronic patterns converged into pillars of light that shot straight up into the sky, condensing the nuclear fuel into black amber. Dr. Shen grabbed the last piece of fuel rod with his daughter's name engraved on it.
After the city was quiet again, Chu Yun's right arm was completely destroyed. Dr. Shen discovers that the newborn's ankle tattoo has turned into an ordinary birthmark. Only Su Wanqing knows that the origami boat under her daughter's pillow is glowing - the chip at the bottom of the boat shows a new countdown: 2,549 days.
