What if...

Two deities/immortals reincarnated in the same mortal world and met or were brothers/sisters.

I'm just bored and this popped up in my head. I would read it.

 

And then what?

 

Vague. Use a little imagination.

 

Don't care. If it's interesting I'll read it. If not I'll drop it.

 

incest

 

until death?

 

Personally I think it could be a fun concept, perhaps especially if written from a first perosn point of view, changing narrators, so we see the shock of remetting through their eyes and see their confusion, anger, joy, etc. It could be very good but I fear it would be easy to get lost as well. Be careful! Haha. But it is a good premise, a good premise!

 

Agree with @Jaded

 

Sounds interesting enough that I would at least check it out. Whether I keep with it would depends where it goes and how it fleshes out.

 

and Blackjack

 

I'd give it a try at least...

 

You need a little more to go with before deciding if it's readable or not. The whole xianxia (assuming deities/immortals or something, JP is probably less of a stretch) reincarnation stuff is already a stretch, usually. You don't want to really asspull much more than you have to, which is already a fair bit in a typical xianxia/WNs. To tie extra links between them is just even more unbelievable. It's not the worst idea, but anyone who is put off by incredibly convenient plot circumstances will probably be skeptical about it.

 

god Mo and god Su were two grandchildren of a greater deity, tired of their constant squabbling over who was best and which one their grandfather like more, Rick banished them to the mortal planes and told them that the first one to get back to heaven would be his favorite.

Toss in a few stupid powers or some opposing circumstances and you've got your standard "next generation of gods trial by fire" story

 

I would like more sth like magican reincarnated into sf world

 

two gods made a bet and one of them was bored so a brother and sister was reincarnated into the world of xianxia but they are from parallel universes

 

sf?

 

@Satan Imagine it D:
Then they do Incest stuff?
-Onii-chan your big and hard thing feels good.
Or
-nee-chan you beautiful red 3rd mouth is so tight.

 

Sounds retarded

 

It sounds like you'd like this fiction.

It's called Until Death and I recall it being phenomenal. It's completed and also has a standalone prequel. I recall most of the authors work being really good and your question reminded me of it.
