Comedy: 5/5 Gold. This is the best novel after A Will Eternal (which has been said to be more funny than ISSTH, AFAIK), in terms of comedy.
Romance: 4.5/5 Aaaah, the cute fluffy moments heal your hearts. Harem progresses nicely, and you can see that MC's "true love/heroine" is Xue but he does appreciate other beauties. The scheme he puts in conquering He family's daughter is the most commendable one. Lemme warn you though, don't read if you're offended by lolis or harem, and the start of the romance is a bit cringy (when Xue attempts to rescue MC)
Action: 4/5 Although the hero is OP, he still has many people above him whom, to defeat he has to use several schemes or rely on fate at times (not too over-bearingly lucky though). His abilities are slowly revealed, and he knows how to act calm/arrogant/loving and any one aspect of other MCs in other novels (one at a time, with certain people). He is only OP for people of his power level, there are other stages above the ones he is at as well
Mystery: 4/5 Although it is a bit predictable (I don't think this is a spoiler but my guess is he is the devil king), it keeps you going
The combination of all this gives you a perfect novel which you can binge even if you're bored by all the xianxia/wuxia skimming (which I frequently do)
