Comments of chapter undefined of Eternal Emerald Dragon

I'm further along then this chapter, but as I was reading my mind kept coming back to here with a question. Will he ever return to this realm? If not will his knowledge of elixirs, weaving, forging, and 6 elements/elementals(harmonies) be spread here some how? The only reason I'm curious is because of the relationships he's made here. If it's to much of a spoiler I understand but thought to ask anyways. Great novel/story.
