If you haven't read these yet I'd check out King's Maker and Two Souls. Ghost Child is good too but there's something wonky going on with the updates rn ;(

It has such beautiful detail art, I really recommend

Blood bank is amazing, I read and re-read that a couple of times.
I'm waiting for king's maker to be complete.
Mo Dao Zu Shi is the best thing ever, I'm afraid I'll go into a hardcore fangirl mode if I'll speak any longer of this, but it's my fav novel ever
And the last one, I think it's also ongoing?
But still, thanks for the recommendations!
I'm in a mood for some historical yaoi. But I'm lost because I already read a lot of those, and the filter doesn't bring anything good.
So please drop some suggestions????
