Today, two hundred years have passed since underground cities became the main settlements of human society. People have almost forgotten what the sky looks like.
Underground cities with depths ranging from one thousand to five thousand meters are spread all over the world, forming a huge intertwined system that continues to support the evolution of the "human" race. And just a few kilometers away from here on the surface of the earth, dozens or hundreds of "nobles" live scattered.
"I sometimes feel that it is very, unfair." Xu Yang spat out the word "very" hard to achieve the effect of "gnashing his teeth", "Children on the ground can grow up watching the sun rise and set as soon as they are born, but many people in the underground city will never understand what the word 'sky' means."
"Liu Zixu, why do you think so?"
In ancient times, people who died in the family were referred to as "ancestors under the earth" and "ancestors in heaven." It's better now, all the living people are in the world, and those on the ground are all wandering souls.
"And the ground itself is the biggest lie."
