The Non-Existent Solar Age

When the doomsday comes, all the satellites crash for no reason, and the surviving people are forced to leave the city and go into the mountains to build new cities and new societies. Since then, human history has entered the "Dark Age" full of lies and despair. "You taught me what it means to be straightforward. You are... My light." (This is an unfinished series. People's problems will never be finished. Finding solutions is the ultimate goal of this book. The whole book tends to be slow-paced and more focused on logic. There should be no exciting plots and it will be relatively calm.)
