I slept on this thought for a night in order to not be too hasty with my judgement, and, after careful consideration, my opinion is that you should delete this chapter entirely and pretend like it never happened. Introducing the Chi was already way inappropriate and I guess most readers were OK with that only because your first and third wish were extremely underwhelming (the ring should have been space magic and the disease immunity should have included magic immunity to make them decent) and we gave you a pass because the MC desperately needed a way to get better and fast at that in order to be prepared to shine once canon started, but you obviously interpreted it the wrong way and assumed it was fine to go completely ballistic and totally wreck the power level of the setting which should never be done post production but only as a premise (meaning the MC should have known it was AU and be able to wish accordingly) also his aversion to magic its irrational and the fact that he didn't account for it in his wishes its a great oversight that was ignored by the readers because you needed some kind of "risk" besides the Night King to motivate the MC's development and give him some challenges but now that you opened the flood gates to literally anything, the whole premise and expectations are completely obliterated and 95%+ of the readers myself included won't stand for it.
I can understand using a bit of AU but crossing over with someone like shanks from one piece is gonna to destroy the power structure of your story. That man can slice mountains in half with a swing of his sword and u put him in a weak universe like game of thrones. In my opinion it doesnât really suit it in this story
