Im a bit tired of the MC'S that are reincarnated just forgetting or not using in any way his past life on eart , i would like to read something where the mc actually thinks on how crazy is to be reincarnated in a fantasy world , and he also tells someone .
Azyl Academy by Chris Vines. Just started reading it, basically tells his new family he is reincarnated asap. They exchange information about each-other's worlds. Not sure if it's any good since I'm only a chapter or two in so far.

Your best bet is a Japanese or Korean novel or an original fiction like the one above Like Lord of Mysteries proved, transmigration is just a gimmick for these novels, the previous world is irrelevant. Maybe you should try Quick Transmigration novels that have world hopping, at least in those stories, the worlds are relevant to the plot even though I dont have experience reading them Summon @ludagad @readerz
Not exactly really xianxia. But Dominion's End has a MC that comes clean to her new family that she's been reincarnated into their brother. After a few chapters at least.
Extraordinary Genius tells his wife of his past life, but in a storytelling mode. Mainly because he's gotten involved with his old wife in his new life, so he can't really pick amongst them that easily.
There was one written by a westerner, can't recall the name but i know there was a copy of it on storiesonline.net with smut in it. MC and a few others get isekai'd to xianxia world. Dude was an electrician that got shocked to death, his understanding of electricity ends up with him gaining that affinity. Together with a scientist they crack how to gain affinities through modern science experiments. I do believe he tricks the female into gaining a lust element affinity. https://www.reddit.com/r/noveltranslations/comments/5jho4w/rec_en_nsfw_techno_cultivator/
Serial Transmigrator MC tells his siblings that he is from another world and wants to return. If I remember correctly, he also wants to create cinema in the xianxia or xuanhuan world where he is. Edit: This MC too.
