The Hedonist Sword God by Ero_Saint

A below average story. Not a single female char has any character development. The main two sword female char just exist as encyclopedia and golden spoon. Cultivation is also trash. ML just jumps levels and doesn't even need any resources to do so except maybe s*x during early few levels. Also cultivation system is also very jumbled up and seems like done by someone without much thinking.
The MC has a pocket realm in which he can store living people and can carry them around. If u read the story u will find that who ever joins his harem, the mc will take them to this pocket realm. They people there cannot come out on there own from there and the realm is also not very large( takes about 3hrs of flying to circle around). At this point u will fill that the harem members r imprisoned there.

a big harem (40+ women), good r-18 scenes, incest, also the rhythm of the novel is fast and satisfactory for a cultivation novel, what a cultivation novel takes 1500+ chapters, this one does it in less of 400 chapters (I'm talking about cultivating from the mortal realm to the immortal realm and all that)
