Good idea,but world building is lacking, mc doesn't develops his powers and gains new abilities that are ignore do to him being op physical. Too many worlds are merged at a fast speed, plus it has too much nationalism that ruins the story. Like no matter what only China has strong and many transcendent or the fact that only Portal discovered is in China and the logic of portals is ignored after. Most important for me is that he has too many massy abilities without any synergy most of them he doesn't use after one time.
