The End of the World: I Started a Building and Became the City Lord

The end of the world is coming and the world has fallen. Social horror programmer Shen Nian hid in a rental house waiting to die, but was hit by something called the "Human Colony Rescue System." The system says: Build a house, take in a younger brother, defend the territory, and save humanity. Shen Nian: ... I just want to live. So— While others were fleeing for their lives, she built buildings; while others robbed her of food, she built cities; while others survived, she built a country. From a dilapidated building to the last city of mankind, she just wanted to survive. How did she become the city lord of all mankind? Shen Nian (expressionless): Don't look at me, I'm not a good person. Internally (crazy screaming): Help, I don't want to be a city lord, I want to go home and write code!!! - No CP, pure female protagonist, men are all tools, and the female protagonist is uniquely beautiful.
