Masters of Lightning Knives

Description

A young orphan was alone in the world until he meets the master of a secret form of martial arts. To learn these otherworldly techniques, he will need to endure years of his sadistic teacher’s grueling and weird training. But why does he have to do laundry, cook meals, or play instruments to learn martial arts anyway?! If he can survive long enough (and if his massive ego doesn’t get in the way), he just might be able to wield the unstoppable lightning knives. Will he make the cut or be sliced down to size?

great art and hype moments but literally nothing happens until the 4th season 😊 by reading this u will trap urself in a vicious cycle of addiction where u read 50 chapters of buildup for 1 panel where the MC uses his uber OP biroe knife technique. Me btw i'm trapped.

i personnaly love this story and if you read the review of people who don't like it's just about pacing because it's a bit slow, but I find it pretty good. It's one of the only manhwa here who take time to develop side characters

A complete waste of time. Skip this.

Plot never goes anywhere.
It's been gone for almost a year but nothing of importance has happened since it returned.
I just wish that the artists are getting paid good because they're the ones carrying. The art is good. The plot is pure dogwater.

reviewer above doesn't know what he's talking about. a plot that doesn't move is not a pacing problem. "pacing" implies movement this one DOES NOT MOVE AT ALL.

also, beating up your students every other chapter is not chatacter development. they didn't go on a journey of self discovery. there was no deep enlightenment or learning from ones mistakes. they just got beat the f up like a bunch of dogs for the laughs. it wasn't funny the first 10 times it happened. it won't be funny the next 50 times it will happen. this ain't tom and jerry.

if you're the type of person that reads with your brain turned off then go ahead you might like this. but some of us actually care about the story and want to see something new.

if you want a sort of similar story with a plot that actually goes somewhere and actually better, just read Memoir of the King of War.

"clasic" martial arts story

by Joese
3 years ago

Rating: 1.0 / 10.0

Edit: crazy how after a year the story hasn't advanced, she's still suspicious of the same things ... If you havent reached ch 100 I recommend dropping it before you get more invested.

The story starts with the cliche mystery man making the MC his sucesor and only giving him chores. The MC has a tragic background and even though some parts are a bit stretched/repetitive, there were some comedic moments that made up for it and the MC wasn't stockpile .

Everything until ch100 is more or less fine but the author drags stuff way too much and includes/ forgets way too many elements his cooking/cleaning abilities disappear after the first ark, I mean the whole reason he got to be a disciple were his carvings and the are ignored after the first chapter. The worst part is how after the MC trains the academy guys his personality changes from a more or less free spirited and untrusting MC into a typical arrogant Chinese MC, stealing anything without context and constantly having a higher ground by acting ignorant. The ignorance cliche is abused more and more as the story goes and he learns many irrelevant secrets.

The murderer/rapist guy way given lost of screen in the first ark, but it didn't add anything to the story and is one of the best examples of how they drag important stuff and leave it without a conclusion, they just randomly mention him without advancing the plot. Or how the only consistent objective the MC had (finding his friend) is shattered when he destroys her memento and acts ambiguous with her. Currently at ch139 I'll just drop it, since there haven't been any satisfying conclusions and only cliche subplots are added.

Amazing, stick to the official translations

by renecop545

Rating: 7.5 / 10.0

I really love the interactions between Ryu-Yeon and his master, he's precocious yet endearing in a way that's really well this. The only thing that hold this back slightly is that several scanlation groups have all at various points in time worked on this, so the translation quality can get inconsistent between translators, but the story is hype enough that I keep coming back for more (there are also official translations out now that are quite good in quality, so if you're reading this for the first time I recommend going that route)

Update: downgraded this series from a 10 to an 7. The first 100 chapters are incredibly well written and poignant, but the next 100 chapters have been dragged out like a bad kdrama. It's a bit puzzling as apparently there's a web novel that this is based on so there's no need to slow down plot progression to a snail's pace. It's not been bad enough to ruin the story, but it has made the series an incredible chore to read when it's been very fun and exciting before.

Can it get any more boring

by skynet5c

Rating: N/A

Every single chapter in a nutshell:

"OMG master stop beating me up!"
"Haha! Give me your money!"
"Where did my disciple run off to this time??"

Repeated ad infinitum. At first it was funny but it's been 68 chapters now and I'm getting bored of seeing the same gags over and over.

Nothing actually happens in this manga. 90% of it is just slice of life stuff like cooking and cleaning. The other 10% is just shady intrigue conversations between shady dudes. It's been 68 chapters and nothing significant has happened.

The only 2 types of relationships in this manga: borderline abusive master/disciple, and the most superficial romance cliches (guy saves girl, girl falls in love with guy). That's it.

Imagine Gosu, except it's just the MC running errands. That's pretty much what this manga is. I'm close to dropping it.
