Only two intact cities remain in this wasteland world.
Recently, one of them collapsed before everyone's eyes after losing its City Child.
Now only one last city remains in this ruined world.
Taking this lesson to heart, everyone decides to find the last City Child. He should stay in the palace they've painstakingly built for him, like a canary kept safe in a cage.
All it costs is his personal freedom, and he gets to join the program to raise a useless layabout. That's a bargain, isn't it?
But Ning Shi, the last City Child, is as stubborn and hard-headed as his name. His motto is: I don't want to lose anything in this life, least of all my freedom.
Ning Shi: "Then we'll all go down together."
His buddy Ye Guzhou: "There's no need to go that far, is there? We can start by beating them... I mean, persuading them, then become the masters of this city, and go out and have some fun... I mean, in your words, protect the world."
Ning Shi: (ー_ー)!!
You left out a few too many words...
Later, after physically persuading the stubborn old fogeys, they use the City Child's powers to take control of the city and transform it, planting the seeds of new cities. One small city after another rises from the wasteland. Ning Shi and his buddy Ye Guzhou truly embark on the path of protecting the world.
It's just that this buddy has far too many ideas...
Ye Guzhou: "Little Shi, do those new cities count as your children? If they do, then I'm their father, too! Should I help take care of them while I'm at it?"
Ning Shi: "..."
Ning Shi: "Don't. What if you take care of them to death?"
