The end is coming.
Global power outages, communication disruptions, and cities fell.
Hou San is just an ordinary maintenance worker, hiding in the underground maintenance shop waiting to die.
Until he found a broken war mecha deep in the ruins.
[Repairable target detected.
[Repair success rate: 0.01%.
Do you want to start repair?
Hou San: "Fix!"
From this moment on, his life completely changed.
Broken generator?
Build!
Scrapped industrial robots?
Build!
Abandoned military production line?
Build!
A war mech that lost power?
Keep repairing!
While others were still fighting for a piece of bread, Hou San had already built the first mechanical base in the ruins.
While other survivors are still looking for shelter, he has begun to resume industrial production.
Steel, energy, robots, mechas, satellites, nuclear fusion...
Little by little.
Hou San discovered that he never repaired just machines.
But a civilization that has been destroyed.
Until one day, the super artificial intelligence sleeping deep underground reawakened.
It looked at the mechanical army behind Hou San and said slowly:
"Human civilization has been wiped out."
Hou San raised his head.
"Then start from today."
"Build a new one."
