There is no sky in the dungeon. The light array has been shining for twenty-four years, and the mechanical broadcast repeatedly said: The ultraviolet rays on the surface of the earth are so high that people will die if they go up there. Maintenance worker A Guang believed in it for twenty-four years, until he fell into a crack in the ground during an inspection and saw wild forests, sunlight, and a girl with golden skin.
It turns out that the sun has already set. The management sealed the sky with a dome and locked a million people under the lamp array as their own private property.
A Guang said nothing. He saved screws, sharpened screwdrivers, and used the three seconds when the lights went out at two o'clock in the morning to practice lock picking. Three months later, he pried open the dome control cabin and poured warm golden sunlight into the underground city.
The lock is unlocked. But when the sky falls, the person who catches the sky has to stand up on his own.
