This is a very unorthodox [pseudo] science fiction novel.
On June 14, 2030, the earth died.
However, he unexpectedly survived and was taken as a foster body to a powerful planet hundreds of billions of light years away from the earth. I don't know how many years later, he was awakened from the darkness, like a child in an orphanage, and was adopted by an alien family.
Everything is different. He can't move in a different place. How can he find his former self?
(The plot has already left the introduction, don't believe it)
It's a bit sweet to break away from personality but not stupid & prone to evil spirits and animals at every turn
