I’m pretty sure it wasn’t a cultivation one , at least not in the sense of the levels being named the standard ones . From what I remember of the characters the protagonist was born in to some rich and/or important family in this world and goes to school. The only other thing I remember is that it didn’t have many chapters and the chapter I last had available had a red haired woman who I think was his older sister picking him up with a military escort in some flying car / shuttle ship type thing.

Still looking for this!! If anyone has any help or thoughts!!

Only bump after 7 days

A just ruler amongst tyrants

Apologies about that! Will keep this in mind for the future!

Now that its been more than a week I think its okay to say that I am still looking for this, I have been looking for it myself every day since I made this post but still cant find it!

from your description you are looking for a series with these parameters

• Manhua (from china)
• Male protagonist (you mention 'his' sister)
• Sci-fi

From your description I will make the assumption that it is not
Girl love (yuri, shoujo ai)
aimed at a female audience (josei, shoujo)

there are not that many series that fit those parameters

Not knowing your preference it could be BL
Try these search results <700
https://www.mangaupdates.com/series.html?type=manhua&genre=Sci-fi&exclude_genre=Josei_Shoujo_Shoujo+Ai_Yuri&perpage=100

If you want results without BL (yaoi, shounen ai) <600

As far as I am aware it wasn't BL, and I went through both links just in case but could not find the one I was looking for I read a lot of chapters of the ones on those links just to make absolutely sure. I still have not managed to find it yet unfortunately.

For additional context I just remembered: I am pretty sure he is like a useless young master type, his family seems rather important like on a societal level in my memory but hes kinda ass at everything / mid at school and stuff.

i think i remember reading this on mangadex a few years ago. try searching there. if you're looking for things on manga updates in the future, don't search with the "female protagonist" or "male protagonist" tags because they're very underused and you'll miss a lot of things because each of those number only to about 2000 when there are obviously much more manga on here. feel free to add those tags yourself for series that you see that don't have those two tags if you want.

At this point I am simply just looking at Japanese and Korean ones too even though I am basically certain it was manhua, just in case I missed something or am mixing something up.

Still looking for this one, I still have no idea what it could be its like I imagined it, but I am almost certain it is real also. I do not know why I cannot find it at all though.

Anyone got even any possible idea about it? I am still looking for it unfortunately. Apologies if I have revived this too many times and should just stop looking
