Review Detail of Firelord in One Piece : Kingdom Building System

the author has a big problem with he/she, him/her ,himself/herself. the author is trying to make the Mc look smart, but instead, he made the rest of the world brain dead. The Mc is bragging about how he has spies everywhere but has no. He braggs about having an army of op anime characters but has only hashirama as slave. Hashirama this ,hashirama that , hashirama go bring grass, hashirama go deliver some tree here and the there ,hashirama is just a slave for the Mc getting so tired of all the hashirama spamming. A lot of potholes. I love kingdom building ff, but this ff just spams hashirama too much. 140 chapter later, and he has only hashirama as a fighting character. And the Mc have the world government under his feet after 10 chapters
