The Failed Swordsman Who Became the Strongest After Spamming the 100 Million Years Button


Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

There was a mysterious old man who approached the failed swordsman with the “100 million years button”. A magic button which can achieve the same effect as training for 100 million years if you push it.

The failed swordsman who pushed the button had his doubts, but immediately felt tremendous power rising in his body. So he pushed the button many times.

However it was a cursed button. The moment it was pushed, he was confined to the 100 million years prison of time. The first 100 years were devoted solely to training. After 1000 years he had forgotten why he swung his sword. He stopped thinking completely after 10,000 years had passed. After 100 million years he became crippled and finally managed to return to the real world. At the same time losing all his memories from the past 100 million years, the only thing that remained were his sword techniques. “I can become stronger just by pressing the button!” or so he thought and pushed the button many times after that. Foolishly trapping himself in that 100 million years of hell each time.

As he continued this loop, he began to think “If I destroy this world, will I get out of here?” A few billion years later, he finally escaped from the loop.

This is the story of a failed swordsman trying to make a name for himself in the world.

Going to preface this by saying that my actual score for this series would probably be about a 4.3. It's an entertaining read and while it doesn't keep me on the edge of my seat waiting for updates like some other series it is one I've come to expect to brighten my day a little bit. As far as the MC goes he's a hardworking likable individual and I often find myself entertained by many of his qualities not related to swordsmanship such as being a world class cheat when... more>> it comes to card games.

The MC is an herbivore but it feels like a more natural fit for him given the lack of ecchi themes and characters in the series. Also, I would say rather than being fullblown OP he is OP enough to get by and has all the potential to really shatter the worlds reasoning at some point. The author wants to drag out his development over time but not write in any over dramatic turns that would make it frustratingly slow.

A single complaint I might have is the lack of character development for the character Rose, she honestly just kind of exists and the author should really flesh her out better. <<less

I don't understand all the hate the MC gets from the other reviewers. They expect him to be amazingly OP with all his training, which he is, but they don't grasp any of the other factors presented in the story. It seems like they want some isekai protagonist that beats everything with one hit. I personally like that even though he is OP, he still needs to try in the more difficult fights. The character growth was also enjoyable to see; seeing Allen go from having zero confidence in himself... more>> and his ability to having friends and slowly building his confidence in himself and his swordsmanship is nice touch to the story in my opinion. I would say don't pay attention to the reviews and give the story a read and see how you like it. <<less

I like the first three translated novels so I decided to read the raws using google translate. It was a bit disappointing. He seems to be the stereotypical passive Japanese protagonist that allows people to push him around.

... more>>

*This is what I understood from the raws so there could be inaccuracies* After spending a billion years stuck within an isolated dimension he finally "escapes", by escape I mean he was able to slowly cause a tear in the dimension and get out when the countdown reached the end of the 100 million loop, I think that was when the dimension becomes most vulnerable. He wakes up, first thinks it was a dream but proceed to realize that it wasn't when he beats that one guy who talked sh*t about his mom. You would think he would have some sort of psychological issues being isolated for such a long time. Either act dead, emotionless or be extremely crazy/expressive since the dimension would prevent him from have strong emotions but nope. He is just your normal, strong, filial piety following, good neighborhood youngster. I kept on reading since its not that bad but stopped when I realized what kind of OP character we got. He was having trouble beating an opponent from the opposing school (he ended up going to one of the top five school, current ranked 5th and been slowly on the decline so now its his responsibility to bring it back to the top #MakesHisSchoolGreatAgain) and was about to get killed when he loses consciousness and his other self takes over (a wild psychological disorder has appeared!!). His physical body changes, hair becomes longer and white and gets some black tattoo going down his eyes. He proceeds to destroy the opponent and was about to kill him until one of the main harem members stopped him and begs him not to do it. She wants his old gentle self to comeback. At first he doesn't listen but then finally stops when he was going to do the deed and proceeds to faint. Keep in mind that they have only known each other for about 1 week but since she is harem member #2, you gotta show some face. Scene skip, the headmasters of the top 5 schools are discussing how to discipline the two contestants because both broke both the rules. His opponent was also going for blood before getting the sh*t beaten out of him. So they decided to suspend the opponent for a month. When it gets to the MC, they want to force him to dropout but the resolution fails 3-2, so he gets to stay in school. The top two schools don't want to lose their position hence trying get rid of him. I dislike the fact that even after spending so much time training he doesn't have fate in his own hands. Swordsmanship is just one aspect, it seems people can have soul weapons or something like that. His mom knows the old time hermit so there is some background movement going on.

Inconsistent af.

He spent 100 years to mimic and improve 4 different styles. Now if you wanted the best genius of all time they might be able to do that in a day

So his 100 years is a day in super ultra mega genius time. So let's add it up. A year is 36500, 3 years is ~110000, that makes his 1.1 billion to be ~30000 years of time as a super ultra mega chicken haxor God genius.... And he gets his ass kicked by a 15 year old.

I was so disappointed in this one, you know the saying:"The higher the expectation, the larger the disappointment"? The idea was so great, I was wishing for a deep delve into human psyche and how being trapped for millions of years would affect his state of mind and how he views the world. However, you know what's better, why doesn't he just forget everything! What's the use of the title if it literally has no other effect after chapter 2! It's just a useless powerup mechanic at the start of... more>> the story! What use is it if it has no effect on the story, should've just made him wake up with those powers and it would make no difference. Makes me mad just thinking about it. <<less

I find this novel quite badly written and not well thought.

1. Author is not sure if it is medieval setting or modern one, you got no cars but there is electricity and modern electronic.

2. The whole “mystery” about MC mother and Time Hermit is to forced, illogical, has many loopholes, and has no sense at all...

Not worth your time...

About translation, I noticed that comments under chapter are heavy moderated, and negative one tend disappear or not appear at all.

Interesting premise for making an MC who is OP and it making some kind of sense but the Author "half-asses" by seemingly nerfing the MC and always making him just as powerful as he needs to be for the plot. Other reviewers already explained the Tournament where he struggles a lot as an example. It is later kind of implied that he actually really is super OP but he has to "unlock" his power and getting it from his "Soul-Dress" which are kind of like Stands from Jojo or Zanpakoutous... more>> from Bleach but much lamer.

I really tried to like this but it is way too much "Shounen" for me. Characters are cookie-cutter, predictable and so is the plot. MC is also the typical "herbivore/beta" who gets a harem for no real reason other than being moderately powerful and a "nice guy". All girls and women seemingly fall for him immediately and obsess over him while he keeps them all at some distance (typical shounen).

Other than that the setting is also very strange. You've got a seemingly typical medieval-type fantasy setting with swords and magic but at the same time, there are also helicopters and jets flying around. No idea what's going on there. <<less

Everything is good in this novel, would have given 5 stars.
but everything goes down drain if MC is spineless dumb moron, I mean even after 100 Million Years (which made him mini-saitama), he acts like typical spineless moron

A training of billion years and you have problems to defeat swordsmans of your age, seriously? Wtf, he sever the small world of the time heremite with a slash!
The personality of MC is just more of the same. I think a billions years of torment, even if you only vaguely remember it like a dream, would at least change his personality... disappointing.

I've read a lot of weak stuff, but this work made me want to drop in the first 3 chapters lul. Don't waste your time, it's not worth... more>> it <<less

As many other reviewers have said, this is utter garbage. The story makes zero sense whatsoever. MC is OP - except he's not because apparently everyone and their dog is even more OP - and that is without having even used any cheat button that allows them to train for 100 million years.

MC should've used that time properly and killed himself the moment he was out, because this whole story is shit. At least it would've ended at that point and we wouldn't have to suffer reading this garbage.


I wanted to like it, since the premise sounded good, so I kept on with it. But no, this train wreck is not salvageable in any way, shape or form.

Author should just cut their losses and write a short chapter saying "and then MC realized he's a useless waste of space who can't do anything right and killed himself. The world kept on going because the MC was as insignificant part of the actual world as an ant is. The end."

Started with an interesting premise, but the shoddy world building rears it's head (is it set in modern times or not? Why is everyone so into swords?).

... more>>

Then we get to the tournament when we face 2 genius students the same age, and his character flips flops a bit here. The first opponent traps him in a sub-dimension for 100 years, and he doesn't immediately escape. Was this not a source of trauma for him? Then the second opponent beats him only for some edgy alternate personality to appear, and that is when I decided it was enough. How was a same age person meant to overcome this guys 10 X 100 million years of training? He can cut space/dimensions!


Overall, not something I will continue reading. I'm sure there are plenty of novels out there with similarly interesting premises, and without so much of the flaws. <<less

As with many other comments posted, I agree with the disappointment of a relatively good idea/concept with poor execution. Granted I do read for enjoyment and can glaze over most plot holes, but when things get as inconsistent as this novel does, I drop it.

The MC spent billions of years, BILLIONS to come out and not even be anything close to remotely OP, not only that, but all that time by himself did literally nothing for his maturity or sense of self. Read this Novel if you wanna casually see... more>> some harem tropes as long as you can handle a passive beta MC <<less

Its tr*sh. If you have read any harem novel before, you can skip this one. Except for the first few chapters, everything is basically like all the other ones you read before... but worse. I don't know how the author did it, but he did.

I was actually interested in the first few chapters. But nope. It went far below expectations. This was how I felt about reading the first few chapters of Arifureta, but then after meeting girl no. 2, you could tell the series was going to turn into... more>> another generic run of the mill isekai harem series.

Expect instant love harem members. So, no character development among any of the side characters. MC is the usual useless MC. Even after billions of years of training nothing but technique, he still loses to a girl who only trains for 1 year (but by s*upid bullsh*t he wins by strength? That's not how you write a good story or characters. Take an example for hero academia, one of the few shounen that does character development really good).

Every single character is just the same as all the other characters you've read in your tr*sh harem stories. They aren't any different, and there's nothing unique about them. I don't mind harems if the characters and unique, have character development, or in general, interesting. But like all tr*sh harems, they aren't. Just 1D characters that even a child can make more fully developed.

This story even steals the Zangpato thing from bleach, and the main character is basically a shittier, weaker, more stereotypical sh*t tier japanese person than Ichigo, with non of the coolness or anything that a girl would even instantly fall in love for.

So basically, the moral of the story is the title is a f**king lie. He did not become the strongest. It should be: "After spamming the 100 million years button, I gained the power to make a harem". Because, that's what this story really is about.

But of course, Japan being Japan, any tr*sh harem story will get super popular, while well written characters with real character development and plot depth will fade into obscurity. I guess as a westerner, I prefer stories with more substance than what is basically a self-insert teenage boy fantasy copy cat novel.

I know, I know, I'm expect too much from authors who just want to join in on the cash grab craze, but just because you want to use the usual troupes, doesn't mean you can't do it well. But considering those well written ones aren't that popular, I guess good writing is poison in the japanese webnovel world. <<less

He barely wins with kids in swordmanship. What happened to his grand swordmanship training of a billion years? He can split the world apart. And yet he is so weak that he wins against mere kids with much effforts. Everything is about swordmanship? Wtf the world is full of magic but nobody seems to mention the magic thing. The title of becoming the strongest is wrong.

I was searching for Japanese LN ('OP MC' tag.) when I came across this series.

Well..... In the summary, it looked tempting but when I started reading it..... you can probably imagine what happens when one judges a book by its cover..... It was not that good as I imagined it to be...... To be honest, the lone attitude of MC in the starting chapters was pissing me off somehow..... When he has such OP power, then why can't you use even a percent of it even though you have mostly... more>> forgotten about it..... One other thing that just doesn't make any sense was that when he trained for 100 years in mind due to some reason during a match then how can you improve so little on techniques that you can't even win against that opponent.....

But this is not the sole problem here..... the side characters don't get proper attention and they are ignored on important occasions..... so don't expect anything from them......

About 'Action'..... The scenes that were written are somewhat good.....

This series will greatly depend on one's taste....... It was my personal opinion so don't take any offense......

In my opinion, it was good nor bad..... <<less

Extremely disappointed, this series had a lot of potential but it turned to standard cliche story (in a bad way, I love cliche). It becomes more visible as you read more how bad the pacing and the writing are.

Only recommend this if you haven't read a lot of Japanese novels because I've seen a lot of other novels using the cliche troops a lot better than this one.

I would call myself an isekai tr*sh and a lover of these kinds of novels, but this novel is pretty sub par compared... more>> to others.

Mini spoiler:

MC trained for 100 million years, but I would call him no more than average compared to the strong ones.


Trained for 100 million years but can't beat a talented opponent around the same age. Have to resort to standard anime cliche were MC borrow power from unknown entity taking over his body (aka bleach ichigo hollow power). <<less

I've had high hopes for this one upon reading the teaser chapters but sadly it failed to deliver. I was hoping that the MC would still have even a slightest bit of intelligence coming from his million years of training but alas, we were left with a generic beta male MC which had no hope nor dreams of whatsoever.

Great premise, could have explored interesting concepts. Instead it's almost a carbon copy of Ichigo's (from Bleach) or Ikki's (from A Chivalry of the Failed Knight) Power with the EXACT situation as Xenoblade's protagonist. The explanations for the events that happen make no sense. We get no background on the world, why is there swordsman? Is the modern world technology powered by magic or somehow guns or ranged weapons were never invented in this world. How are high school student so powerful without them being put into a STRICT military... more>> school? (At Ch17. The MC hasn't recived one lesson even though he has been in school for over 3 years and in a new school for a week. Somehow they have one, one hour classes per week?) <<less

Please form your own opinion is what I always say.

C'mon, you mean to say that after reading 10 chapters you can say with certainty that it deserves a 1/5? I doubt.

If you're looking at this page right now, you know exactly what you're looking for: Some op guy, swords and shounen shit.

On to the review now:I like it. It starts off strong. It has some weak parts but it does somewhat explain why it is so. MC is basically insane (in not a very bad way). He's been stuck in... more>> there for a billion years but his 'training' seems to be locked away and he unlocks it through 'willpower' and 'resolve' and all that shit.

His sense of time is gone. He is actually sent to prison for another 100 years in his mind while fighting some dude but he spends it training and thinks it wasn't enough.


MC is a kind of a generic op guy but he's not unlikeable.

The power scaling is comparable to Dragon Ball Z/Super as in there's always someone stronger so take it how you will.

The side characters don't get enough time imo so that's a con.

Well I'll keep reading it until it shits the bed and it becomes boring so yeah.

Like I said in the beginning: Form your own opinion. Don't listen to me or anyone else, trust me. Every review place sucks ass. MAL? 8/10 and the next one is 2/10. NU? 5/5 and the next one is 1/5. Who do you believe? No one and you read it yourself. <<less
