Just that. Say you want to zoom past the grind, how do you show the progress and smoothly integrate that skip into the story?
BTW: Please read my story!
Alan is a nobody. A forgotten face in a world that barely noticed him. After a two-year stint in prison, he finds himself thrust into the Tower Endless, a brutal other world where he faces monstrous beasts. It's a chance to prove himself, to escape the life he's always known,...

Time skips are one of the things the author really butchers or perfects. In my opinion a good time skip is a time skip that doesn't feel like-excuse my language-an ass pull. If you have read the Sun Eater series by Christopher Ruecchio ( f you hadn't then please do, its amazing) in the series each book has a giant time skip, that can range from 50 years to 300 years. And it never felt clunky except for the first time. In a good time skip, the MC is not the same, you SHOW why, don't tell. You can't make a 10 year time skip and the MC is still the goofy guy that he was 10 years ago, he maybe is, but now he has more of an edge or some melancholy, because 10 years is a long time for humans and many thing can happen in that time. Not just the MC has changed, but also the world, a human world is never the same after 10 years, I mean look at us. Is our world the same as it was in 2014? No, and your world needs to reflect that.
A bad time skip doesn't do any of what I have mentioned above. Time only passed in name and not in reality, that is why I dislike a lot of Xianxia novels, because like 10000000000000000 years pass and humans are still fighting with sticks or swords. Like bro, we went from horses to space craft in less than a 100 years!
I'm sorry if I sounded a little mean there, no bad feelings. But, my friend, in the end, do what you think is best. Don't take my words to heart, because my mentality of a realistic world is what have made me go insane while writing my work.
