I read this a while ago and finally decided to finish it and write a review.The story is pretty good at the start but near the end it just makes you question what the point of the story is. Near the end, all his goals have been achieved, he manages to overcome cancer and achieve immortality and other than build his spaceship, there's no point. The ending was incredibly unsatisfying and makes little to no sense, the author had a great concept for the ending but executed it quite terribly.The best part of this story is obviously the fantasy worldbuilding but even that has a strange ending. It's been a while so I may be wrong on some of the details but the general gist is that he made a prototype world and then it's inhabitants escaped it so he made another better world and disguised himself to join it. After that he manipulates some people and parents a girl to be a king, it's a trap. after that things just spiral out of control and he builds a huge floating city that's basically heaven and let's other mortals ascend to become other gods like some discount Olympus rip-off. Then there's a war and he leaves the world to let it develop by itself or something, end of the story in the fantasy world back to irl. Needless to say, that ending for the fantasy world kinda sucked a lot. Yeah that's about it for this review. If the author fixed the ending instead of dropping the story midway and gave the characters better motives and goals, the story would have easily been much better than it currently is.
