Dreamland of Reincarnation of Elves

In the narrow gap between dream and reality, between reality and illusion, I woke up from a big dream. Everything in the dream seemed to be illusory and real, and I came to this world with countless memories. But he found that there were some deviations between this world and his own memory. How should he make a choice in this supposedly illusory world? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
