Literally nothing happens after the dimensional expedition arc. Instead of developing existing characters, author keeps introducing new women (courtesans, or existing character who suddenly has multiple personalities) and shoots himself in the foot when he realizes he can't develop them well. All the previous women keep appearing for 1 chapter and disappearing again as author tries to juggle MULTIPLE relationships at the same time and fails miserably.

Author's overemphasis on Qin Wanru (MC's mother-in-law) is pretty messed up.
It was still ok as an initial joke about her being a mature woman targeted by older men. But author set up way too many sexual encounters between MC and his mother-in-law, from seeing him naked (after MC recovers his sexual function) to constantly feeling distracted since the joke was that his d*ck is huge. Although MC doesn't actually have s*x with the her, this development is really messed up and uncomfortable. Starting to wonder if author cratered to some reader demands for sexual fetishes.

The aphrodisiac trope and sex-to-save-a-life trope keeps coming up. Again, and again, and again. MC can apparently only initiate s*x with his women through these tropes, which is just f*cked up, a huge red flag and completely destroys MC's suave character.
MC slept with his wife to save her life since his "essence" can help cure her broken meridians.
MC slept with his maid because she got hit with aphrodisiac.
MC slept with a scheming harem member, because she got hit with aphrodisiac.
MC has a sexual encounter with an innocent harem member, because she mistakenly consumed the SAME aphrodisiac.
Are you f*cking kidding me?!

Author kept promising 2 chapters per day, which is an insane amount of updates. Might be a newbie author mistake. Eventually author couldn't live up to expectations so you start seeing a LOT of filler... basically lengthy descriptions of MC's harem in a different wardrobe or long paragraphs discussing their body parts.

Holding out hope it starts to turn around...

Here's the rough tally by c450. I can't even rem their names anymore... that's how ridiculously huge the harem cast is. MC hasn't slept with several of them yet, but by the sheer amount of screen time, innuendos, sexual encounters and constant reappearances, it's probably going to happen.

(1) Main wife, cold and aloof.

(2) Main wife's younger sister / i.e. sister-in-law, I'm guessing it's supposed to be the loli type, but author avoided this probably due to worry of ban, MC is waiting for her to "grow up".

(3) Mother-in-law (got hit with the usual aphrodisiac trope, but recovered at last minute since author gave up due to threat of novel ban).

(4) Main wife's busty friend.

(5) Main wife's elf maid.

(6) Ex-scheming adversary turned lover, with all kinds of voyeur/public kinks (netorare since she's engaged? flagging here since someone keeps removing my novel tags).

(7) City lord's daughter, supposed to be the artsy type.

(8) Principal, mature working woman type.

(9) Teacher, mature old sister type.

(10) Medicine girl, some innocent young thing that caters to MC's fetish to bully her.

(11) Courtesan, I guess geisha type? Also supposed to be the artsy type. No idea how she's any different from the others anymore.

(12) Randomly inserted (pun intended) emperor's younger brother's wife who's also an elf, so now author is duplicating characters. I believe it's called netorase (something like "Indecent Proposal" 1993)... someone keeps removing my novel tags so I have to directly flag it in the review).

(13) Scheming adversary's daughter.

Reminds me of another disaster "Ancient Strengthening Technique".
@dysry's review is still legendary, and applies to this novel too.

-- Cheng Shouping, MC's inept attendant that's lazy and frequently retorts to the MC, plays a similar role to the one Gabriel Wong in Flirty Scholar, Fight Back to School.
-- Qin Wanru, Chu Family matriach, resembles Kingdom Yuen/Pei Pei Cheng who plays similar violent deadpan matriachal roles in Stephen Chow films.
-- Ji DengTu, a pervy middle-aged physician and one of MC's harem member's father, is reminiscent of Uncle Tat.

MC's wife reads romance novels titled "Sweet Pampered Wife...", which pokes fun at the fact that majority of modern webnovels have similar names.

Everyone has weird pun-like names that would be hilarious in modern times. His pandering pervy schoolmate is called Wei Suo, which is a homonym for wretched.

When MC is told by his schoolmate that there's a ranking list of 10 School Beauties, MC complains about boring decades old tropes being recycled. The schoolmate retorts that even so, people still enjoy and clamor for it. MC reluctantly agrees.

Character names are often puns of their character design/personalities. MC's sister-in-law is Huanzhao, meaning she tends to fight back/be prickly. A busty harem member Pei Mianman carries the word "man" or "full", in reference to her endowment.

MC obtains a "Heiress Ball of Delights", which is a joke on the urban legend that rich bored housewives would have a special steel wool scrub to use on their boy-toys. It's a reference to S&M and MC uses the ability to remain at near death condition without dying.

MC's body is sealed (reference to A LOT of other xianxia novels), but comically the seal affects his p*nis and he can't get it up. The harem members around him typically make fun of the MC for it, treating him like a harmless gay friend which pisses him off.

-- Women are supposed to be sexually conservative (widows/divorcees are looked down), but somehow wearing sexually suggestive clothes is ok.

-- Technological gaps are filled in with runic powers and formations. There's abundant Ki energy in the air to be absorbed, but there's still a heavy reliance on basic industry and labor. Wouldn't you just extract the Ki as a power source for industry?

-- The academy arc is weird and unstructured. People of all ages can attend, there's no set curriculum. And based on the description, the entire academy consists of just 4 classes... even though they are the most reputable academy across multiple prefectures.

-- MC's System random power-ups can become too far-fetched and don't blend well with the story.
E.g. a skill that temporarily forces someone to acknowledge him as a "friend" is ambiguous and doesn't have any benefits. A torchlight that only shines when it's bright was forcefully applied in an undead scenario when the environment JUST happened to be a place that was lit.
It's a copy of Stephen Chow's "Tricky Brain's" (1991) where a lot of the gags are one-time use and don't fit very well in a cultivation world.

These are just a few of those odd world-building elements that don't always make sense when meshing cultivation and modern science.

He severed a guy's dick, tied him to a tree and swang the severed d*ck in front of him as torture to get information and points. Later he threw the guy, still dickless, in an area full of wolves, lying that he would save the guy if he killed a few but still letting him being eaten alive after 'trolling' with fake attempts of rescue.

Later, a group of bandits get knocked out with poison so he goes with a dagger to each one's throat and asks an impossible question in name of 'trolling' and no matter the answer, he kills the guy in cold blood while their companions watch, one by one, in despair, until the last one. He could just take the bandits to the city, knock them out or whatever, but no, let's kill all them in cold blood, one by one, to farm rage points. So much trolling, so much comedy!

Zu An is our shameless witty philanderer of an MC. He genre-savy, so he knows the common, idiotic drama pitfalls and avoids them with style. Not only that, he somewhat keeps hold of his modern-day morals. Oh, he'll kill people that are after his life but going on a clan-cleaning murder spree is not his go-to reaction. He'll just cripple or chop limbs off instead lol.

His shameless rebuttals are also more on the comedic side. He'll boast about things like arrogant MCs, but Zu An always has a comedic bluntness to it instead power levels d*ck measuring. It makes the dialogues waaaay more palatable that I was surprised to find myself rooting for the MC to troll his enemies.

And it's not like he's trolling people just for the lulz. Pissing people also feeds him gacha points that feeds him plot armor. You know, those scenes in other CN novels where the protag had offended someone they really shouldn't have, gets beaten to a pulp, falls off a cliff, but had miraculously found some bullsh*t artifact that will help them turn the fight around? Yeah, those scenes. I despise those scenes. Trolling people for plot armor though? Hilariously acceptable.

Typically, all the trolling Zu An does should cause friction with the other characters. Such as causing every side character to be too prideful and take offense at Zu An. And in the beginning, that's pretty much is the case. Luckily, some people turn around rather quickly and the characters supporting the MC just wave off Zu An as being that kind of person and support him from there.

The Heroines especially, are great. Chuyan is first introduced as a cold personality, Snow is shown to be scheming and sharp tongued, Huanzhao sounded like a sadistic loli, etc. Then as the story goes, we find out theres more depth to these lovely ladies. Chuyan is actually very girly but had believed she needed to sacrifice her own happiness for the sake of her clan. Snow had made herself into a spy for the sake of her people. Huanzhao's sadistic side is the result of poor parenting and an inferiority complex due to always being compared to her older sister but she's steadfast and loyal.

There's plenty more girls and they all have unique personalitites that it'll take too long for me to write them all. You'll just have to read the novel to find them!

Chuyan best girl though~

Alright, now for the weakpoints in the story.

The Harem. Yes, I've talked about the heroines being really great. The problem is, the girls don't always have the limelight of being with Zu An. They come and go, yes, but I still would have preferred they stuck around the story permanently.
The Plot also has it's ups and downs. Undoubtedly, the weakest points in the story is whenever the author decides to add in ancient fantasize chinese history. So far, there have been only two instances of this and I've had to skip paragraphs at these points because they're so God-damned boring. Not to mention these empire/dynasties sound the same like Qin, Shu, Zhong, Shang, that they fly over my head.

That's not to say he adds them for no reason. There's definitely something plot related tied to these history lessons, but they're still pretty 'eh' because it's not advancing the actual plot but simply expanding the lore.

I've seen the other reviews and most of them drop the story due to 2 points.

The first is the grand total of FIVE aphrodisiacs as a plot device, of which, only 2 of these resulted in something steamy happening to Zu An. Note that Zu An himself has NEVER used these drugs on the girls. He doesn't NEED them.

The second points is that people say the plot is slow. These reviews are often vague but from what I'm understanding, they're dissatisfied on the lack of fight scenes. Keyboard Immortal is not one battle tournament after the next (Thank God!), nor is Zu An some martial berserker that would fly off at the slightest disrespect. No, Zu An is first and foremost a Keyboard Warrior (read:troll) that would use his wits and cunning to verbally assault his enemies.

Not only that, the villains are also smart. Sure, there will be young masters that take offense to Zu An being a street-rat hooligan but those are just midbosses and it only takes 2 or 3 chapters to get their face slapped. The actual meat of the story that takes up dozens or so of chapters are actual smart, scheming villains. There's a lot of political intrigue going on in the story and Zu An has to navigate his was through them instead of balls-to-the-wall fights.

Also unlike most CN novels I've read is that Keyboard Immortal tends to stick with a setting. The majority of time is spent in only 2 locations; Brightmoon City and the Capital. The former of which was spent around 400 chapters, while the latter seems like it's taking 200 chapters already. In other novels, the MC is always moving from one town to the next, with the side characters being just left behind there and mostly forgotten.

his wife crippled herself to save him he is still in his collecting rage point and just in the mood to joke around
