Purge every grammar error from your first five chapters.
Axe the prologue, unless it's an engaging action scene. Most prologues are unnecessary and are so boring as to be alienating.
Axe the currency conversion and cultivation level details unless they're actually iiiiinteresting and plot relevant. Also everything about the magical system that isn't literally plot relevant that chapter or next chapter.
Consider cheesecake/beefcake/...furrycake... cover art. *cough*. Or just cake.
Remove all the meta stuff from your intro synopsis and chapter headers. Update schedules, your personal stuff goes best in chapter footers.
Describe details of weather, geology, interior furnishings, equipment, and so on. Not exhaustingly, but most adventurers guilds and adventurers have barely any words - imagine trying to draw one while interviewing a witness. Just enough words to hint is fine.
Spend two decades working out fully-fledged dwarvish and elvish languages, write the stories in dwarvish and elvish, translate to English. Orcish is grudgingly acceptable for the tumblr/tiktok generation.
