Devouring Evolution from a Carp

The protagonist died unexpectedly and was reborn in the world of immortality. He became a carp in a large sect of immortality. He also awakened the golden finger and started his own path of evolution in this world where everyone can cultivate immortality. This is my first time writing a book, so I may not handle some things very well. Please forgive me and give me your support. Thank you. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
