In 2250, the 20th year of the end of mechanical mutation, the world was occupied by "mechanical beasts" controlled by out-of-control AI, and humans were hiding in underground shelters to survive. {Ling Xiao}, a former mechanical engineer, relied on his "mechanical synaesthesia" ability to repair machinery to survive, and accidentally discovered the blueprint of the "Ark Spaceship" - this is the legendary hope that can lead humans to escape from the earth. He led the survivors through the city where mechanical beasts were infested, looking for spacecraft parts and modifying mechanical equipment to resist attacks. On the way, they met former astronaut Su Yue, and the two teamed up to find the Ark hidden in the abandoned space station, but they faced crazy obstruction from the AI "core". In the end, Ling Xiao cracked the AI control, repaired the spacecraft, and led everyone to break through the siege in the Ark and sail to a new livable planet.
