Hello I'm new here. Can you guy recommend me historical BL novel. I'm okay with untranslated. It will be better if it has 'Royalty' (Sorry for my rough English)
Cold Sands The Path of the Cannon Fodder's Counterattack Ban Lu Qin Jun Hua Hua You Long Counterfeit Bride
Are you looking for pure historical? Or is ancient Chinese cultivation all right? If the former, I’m not sure I have anything I can recommend.
There are a few bl novels in C historical settings that I remember: Sharing Rain and Dew (very short, only a few chapter. Finished and fluffy) Rich and Powerful Chang An The Big Landlord The path of cannon fodder counterattack (translation ia finished) The Ugly Empress and the wife is first (not translated yet. You can read about it on spoiler part. I did mtl the novel)
I have some of untranslated ones. Some of these have spinoffs too if you like 撷兰令 作 者:谢子傒 望江南 作者:竹下寺中一老翁 九王爺娶親 作者:VAINY
Here are some suggestions! Sha Po Lang, Golden Stage, and finally, To Rule In A Turbulent World. These might not fit your taste but they are historical. The first two are completely translated but the last one is still in the works. It might be finished by the time January/2021 rolls around.
Sha Po Lang, ugly prince, and some others, a suggestion would be to click on the novel links that the others have provided and going down to the list part where people created lists of such genres.
