Source: Three Is Falsehood

After the war, mankind entered a peaceful era. At least that's what history says. Gu Zhichuan always thought that he was just a survivor who escaped from another world. Until he came to that remote town. There he discovers that Earth has never really been "ordinary." Some people have internal organs sleeping inside their bodies that cannot be awakened. Some people are born with the ability to control gravity. And the moon that has been hanging above human heads for billions of years—— It's not really the moon at all. A long time ago. Extraordinary civilizations once existed on Earth. Later, they were erased by history. Now, a stalker from another world has arrived again. Eighteen years old is the age when the source organ is completely completed. It is also the moment when all energizers are truly exposed to the perception of the world. And Gu Zhichuan must before that, Teach that child how to live. —— "Have you ever thought about it?" "Why is there never any real evidence of the existence of the 'supernatural' in human history?" "Because of the people I met." "It's all buried in history."
