Merin is reincarnated into a new world.
After he died in his previous world.
And the new world is an extraordinary world.
He is full of curiosity and fear for the new world.
But he is born in the new world as a tree.
Struck in a place.
To explore the new world, he tries to find way to escape from his tree body, or transforms himself to a humanoid.
In the process, he finds the reason he reincarnated into this world.
A mirror, that can send his soul to reincarnate into new worlds.
Authors note- The first volume would be of Merin's life in another world and as a human.
The story is good, but the writing has repeated words, structure of the sentence and other things . I think if you use AI, it would be better to fix your sentences and other things
