I have not read many Master/disciple relationships (only svsss and 2ha). Looking for some black hearted/sinister towards the entire world but obedient towards Shizun dynamic.

Sorry, I mistakenly clicked that one and wasn't paying much attention. Fixed now, thanks for pointing it out. Thank you. Thanks for all the recs, I'll check them out. (*´ω`*) Thanks!
How about Cultivation Retirement Plan? It has a master/disciple relationship, and the disciple is a bit black-hearted...
I would also recommend Mistakenly Saving the Villain. It's not completely shizun and disciple relationship, per se, but Yue Wuhuan (ML) is in a situation where he is essentially of "lower rank" than Song Qingshi (MC), calling him "master", since he doesn't really lead a sect of his own. Yue Wuhuan is pretty blackened, but he's respectful and obedient toward Song Qingshi. Just as a warning though, chapters 2 to 4 or so can be kind of a tough read if you're sensitive. Yue Wuhuan is someone who has been through both sexual and emotional trauma, and his mentality is a bit unstable. Another short but completed one standing at 29 chapters that isn't on this list is My Junior Still Hasn't Killed Me. Again, it's less shizun and disciple and more shixiong and shidi relationship. The shidi, Gu Xuanyan (ML), is definitely blackened. I'm not sure if he really obeys Zhong Yan (MC) as much as it is the other way around though... I think it kind of goes back and forth and is a bit "sticky" in that regard.
Does "The Paranoid Emperor’s Black Moonlight Shizun" have a happy ending? I see the tragedy tag and I'm scared
