As its said above I just want to read a book with the main lead being really old but still has a young appearance and has lots of wisdom and powerful. The genre I'm looking for is a cultivation setting and no harems.
Emperor's Domination. MC is a billions of years old scheming guy, with a forever young look, with peak strength/power. It's like what it's name says- a guy's journey and domination over enemies and the world. The harem tag doesn't mean much for this novel, the MC doesn't stop for any woman/man/friends/sect in his journey, and there's hardly any real romance.
He basically goes from place to place throughout, rearly coming back and if so then only for a short time. So there's a lot of girls, almost a least one at every new place, but the time he spends with them is minimal. I haven't read it in a long time, but I can remember maybe a couple of romantic moments through 2500 chapters, so barely any, and always short ones.
