This was a good find, not gonna lie but I'm still half-half with the Sect creation setup, because it would really risk the overbloating of characters on this story. You are gunning for harem after all, so it's not an exaggeration to say that a lot of characters needed to be developed properly, which ultimately means that slower story plot progression and the setting aside of unneeded characters. Also, just a personal opinion, please don't add the other perverted dudes that Issei is friends with. Man, those guys are irritating. Overall, this is a good story within this cesspool of a site, which is a pretty nice change of pace, thank god.
are you gonna get him a sentient weapon or magic beast? it's an iron rule in xianxia that if there's a weapon, animal, or plants that could cultivate, it'll turn into a woman with green rock skin eventually and if someone with a dream of a harem were to get isekai'd to a cultivation world, only a fool would miss this chance of getting a bunch of waifu rather easily!
