One Piece's Jojo Substitute Messenger

The beginning could be simplified, but if I really want to write it, it would be better to use flashbacks at the end. The third chapter of Conflict has only come out, and the main plot and exciting points are a bit lacking. There are a little too many adjectives, and it's a bit tiring to read. The ability explanation feels a bit weird. I still feel weird after reading it several times. If you have time, can you help me read my book? I can't find the problem myself and I need others to criticize me severely. I also wish you can sign the contract as soon as possible.
