-Writing Quality: For me it is good and understandable, simple and has few errors, I'll give it 5/5 -Updating Stability: 13 chapters in three days since the fanfic was released so far is a very good thing deserves appreciation, I'll give it 5/5 -Story Development: Establishing a clear and explicit scenario for the story from the beginning sings the author and readers of the problems of progress and continuity of the story, because this story has really huge potential, I just hope that the author keeps up with the good work, the story has two main worlds in the beginning with the possibility of adding other worlds, MC is considered a host for a very powerful spatial system that can pick up the coordinates of the worlds and open a portal to move to them, this is a good and logical idea, it is clear that the system was designed to make its employer a global conqueror. Getting started in the world of One Piece is a great start, I look forward to seeing the world of the original protagonist that the author said was the OC. I'll give it 5/5 -Character Design: So far we have seen few characters beside the protagonist, the character design of the hero is good, he was reincarnated from the earth and lived for 17 years in a medieval world without any cheat but he was all lucky to be a crown prince in an empire, looks full of struggle and secret fighting between princes, the story is very good, as the protagoniste is very clever, as we saw how the author explained that the hero has already merged with the ideas of his new world. And we saw in the first chapter how cruel he is to test his food on a person before he eats it, and this is necessary to show his cruelty to others so that they do not overthrow him. Everything the protagonist is experiencing in his new world is very abnormal and I look forward to seeing more of him. I'll give it 5/5 -World background: Dolla's world, is the OC written by the writer, so far we've seen the diamond city where the hero lives, and the world of One Piece we've seen monsters island in the western blue, the organization is good so far and the background is great. I'll give it 5/5

please no=NTR-dense/idiot/naive/betha MC-psycological ......i just wana having fun reading....i have bad rl.so.....

An amazing novel (among the best ones i've read) i like the characters, i like the background and i think this is going to be one of my favourites

Overall: good, could be better, but i had to stop reading this because the writing style kinda annoyed me. I don't want to get headache. Writing quality - 1* (because i put high importance in this. so, stricter than other criteria) Longwinded. Bad reading flow. Sometimes there's missing word and used bad choice of words making it awkward and harder to read. Other than that, it's good Mc is not braindead, that's a plus. Most new novels nowadays have below average iq mc resulting in many plotholes or forced plot. Well, if you have passion in writing and want to improve yourself better. you should read your old chapters and fix what needed to be fixed. This includes your other novels too.

Reveal spoiler

This novel is HIGH-QUALITY STANDARDS. Second, its enjoyable to read and the mc knows what he wants and gets it. For those interested, the setting is 4 years before the start of one piece and it seems likely that it will turn into a multiverse later but i find thats overdoing it with the current setup. The mc "Homeworld" is literally on the medieval age without seemly any fantasy power, just good old fantasy setting and mc having a devil fruit, he already is the TOP dog in his homeworld and his word will be the law... Unless his homeworld is more than it seems. I say this because there will be no need to travel to other universes to conquer his home planet. He can already do so.

This is really a promising story you have here, author-san, keep up the good work, I hope to see a good connection of events between the two worlds and not make us wait too long for events in One Piece world❤️❤️❤️
