Does he ever go back to the mortal realm to check on his family? If so, does he bring them to w.e realm he's going to tribulate to? Thanks beforehand Please just this question, nothing more
From reading spoilers I believe he does go back but he doesn't take them with him when he leaves. Can't remember where I found it, maybe WW. Take with a grain of salt since I haven't read past current translations or MLT either. This might help but might want to avoid it if you don't want to read the entire section. I might try finding the specific section if I'm even correct. https://dl.dropboxusercontent.com/s/ypow8g1zdvz5j16/Spoiler.html So reading part of it he goes back near v14c30. He does not take anyone from his Qin family to the divine realm. So thats about 40'ish chapters from now.
If you read the latest(?) TL'd chapter, you'll learn that people can't be taken with them unless they've already broken through and can go there by themselves. Or if they were born in the higher realm.
