Just to make it clear it is a slow paced novel and I am a new author so don't expect professional work but, I would still request you to try it as I am trying my best to write this story.
Second thing is that in this world lifespan increase as your rank increase and it is very difficult to rank up and it uses a lot of resources. It also take a lot of time to rank up.And due to the long lifespan most of the strong family are large clans.
Third thing is that the protagonist is not op he will make mistakes and grow after making mistake and he will fullfil the dreams he could not fulfil in his original world.
That's all I hope you have a great time reading this novel.
Oh and add it in your library.
