Return from Another World 1960S

In 2030, my soul traveled to another world and lived in a magical fantasy plane for 300 years. I had more than 30 years of memories from my previous life. I was prosperous in the other world with my golden fingers. However, when I successfully hunted for treasure in a secret realm, I was chased by others. After killing one person, I was thrown into the turbulent space by the space master. I didn't know whether I was alive or dead. When I woke up, it was already the 1960s! !
