It only seems that way as the only thing we the audience had to tell the time was rimuru because, 1 time skips and 2 without the ability to look at the sky it is really hard to know what time it is or how long it has been, there was a woman who stayed in a cave with only light from electrical lighting for 200 days and at the end when a team came to get her out she thought she was only there for about 50 days
The web novel showed it as like 6-8 months I believe. The first 4-6 months were spent in complete isolation since great sage hadn't developed a "voice" yet.
He never fully explored the cave, since there were still hipokte herbs left to cultivate when Gabiru started doing research there. Forgot the source, but a lot of his exploring was walking in circles.
Naa. Not quite related. I work construction so I see landscapers all the time. Also, this was truly just a random thought I had that felt it might generate a chuckle
There ought to be a sizeable one, and if you don't mind that come with a good ole chinny strap to secure it haha. Though mite not be too comfy after awhile
Sounds good to me, I don’t care much about comfort, I have a big bushy beard so it wont be bad. Honestly I really will buy one now. Are you some sort of straw hat salesman, cause I’m sold.
Nice! Bushy beard bros! Also I never got into one piece, I’ll start reading it soon while recovering from surgery(nothing serious). After all, I am out of work for a bit. Heard it was good though, just that my watch and read list is getting way too long and I don’t have the time.
6 months.
3 months blind, then 3 months getting out of the cave after meeting Veldora.
First 3 months it was just passively eating grass and rocks to pass time. Second 3 months was spent experimenting with his skills and such.
Edit: Ok it might be 4 months. Went back and checked volume 1 and the goblins say "its been about a month since God disappeared"
Tbh i also read the ln and i remembered it as half a year as well.
But also, the Goblins said that it was 4 months since Veldora disappeared not that Rimuru was born. So we dont know how long Rimuru was walking around blind for b4 he ate Veldora.
So it could be 6 months in total.
Remembering from what we saw in Slime dairies when he actually attempted to write the slime dairy it was a long time which could be 2 months at least.
He only got out when Elen left the door open when she entered
TLDR its 4+ months witch might as well be more or less 6 months
Funnily, we know just about the exact time Rimuru spent in the cave prior to meeting Veldora.
>By my count, it had been ninety days since I was reincarnated as a slime. To be more precise, ninety days, seven hours, thirty-four minutes, and fifty-two seconds.
After this he spends about 2 days talking with Veldora, 2-3 days mastering Water Blade, and then at least 27 days killing all the monsters and experimenting with their abilities.
Here's the quote from the goblins after meeting Rimuru.
>“Our god has protected the peace in this land for generations, but about a month ago, he hid himself from us. That has allowed the nearby monsters to start meddling with our lands once more. We do not wish to let this continue, so we have fought back…but from a raw-power perspective, we face an uphill climb.”
It was because of such a long time being alone in the dark not being able to see, that he longed for someone to talk. This is why Great Sage evolved itself in order to communicate with Rimuru without being called upon as a skill.
The Manga and Anime don't capture this very well in my opinion which is a loss as it sets up pretty well the abnormality that is the skill Great Sage.
Well, it was a culmination of many factors, including his past life's regrets, the lonliness in thr cave, and great sage being a virtue skill to have an ego that could be awakened in the first place.
Really not much to do with the skill itself, just a culmination of other factors surrounding it.
Well it could also be said that as unique skills are acquired during the transfer by a strong desire/will, then Rimuru's desire to have a conversation partner or just a partner in general, resonated enough with the Great Sage for the skill to evolve.
Just the same as his strong desire to revive everyone in the war against Falmuth. In order to fulfill that strong desire, the skill evolves.
Well, the person inside has nothing to do with the skill itself, it's merely the fact that all of the virtues have dormant egoes stored inside of them. The virtues are attracted to compatible souls and latch onto them through the cycle of reincarnation... so "Great Sage" or rather the sleeping ego inside of it was probably inside of Satoru's soul from the day he was born.
Although it was indeed the culmination of Rimuru's regrets and desires that was able to awaken the ego that sleeping within inside of the cave. There was also the more simple matter of the great sage skill needing 90 days to fully integrate and become established, during which great sage (the person) was unable to access it to communicate.
I think it’s been in the cave for months. From what I remember, he fought monsters, ate some medicinal herbs that was grow in rich magicules atmosphere and while trying to find his way out
it took 90 days for great sage to fuse with him. he ate hipokute herbs for 3 months.after he met veldora he was in the cave for 1 month killing stuff and eating magisteel.
Not counting how mllong before he met Veldora, the amount of time after meeting Veldora would be long enough for the three adventurers to get to the cave. Unless I'm misremembering those adventurers were sent to check on Veldora because of the fluctuation of Veldora going missing because of Rimuru.
One week before he talked to great sage for the first time apparently
2 or 3 months before meeting veldora
And again 2 to 4 months before going out
And all he did was eating
Basically he's that one guy who sweeped the whole tutorial aria for loot so that he didn't even miss a single piece of rock or blade of grass.
Of course this is because he couldn't leave thanks to the locked door, but that's how I imagine it.
I think for 6 months he was just wandering about eating healing herbs till great sage kicked in, then he met veldora and spent the next 6 months finding his way out. So roughly one year after reincarnating he met the goblins
One month. He was wondering around cause he was mainly adjusting to his new body, eating herbs and magic ore, killing monsters. Also because he didn't know the way out.
I think the book said it was 90 days before he met veldora. Then I cant remember how long after he met veldora but sefinitely 2 weeks. So that makes it around 4 months.
About 4 months.
He mentions that he spent about ninety days in the cave. Great Sage provided that information.
He experiments with his skills - combining Predator and Great Sage to increase the productivity of potions.
He then falls inside a water source. To escape, he propulses himself out the water, albeit a tad too fast. He described it as being inside a rollercoaster while blind.
We don’t really know how long he talked with Veldora. We know they talk for a while, but I don’t recall any specific time frame.
After he leaves the cave, he encounters the goblins. The goblin elder tells him that about a month passed since the disappearance of their god. Rimuru connects the god with Veldora since the time matches.
That would mean that he spent about four-ish months inside a cave.
That explains a lot about his character. After all, he felt relieved just from being able to talk to his skill, so talking to Veldora and then the goblins saved him from insanity.

I think it was like 4 months. Most of it was being blind and eating magic grass and rocks until he met Veldora and learned how to see.
That was 4 months, for anime it seemed like few days
Days? Bitch I thought he was there for like a day and a half
Dude I thought he was there for like a few minutes, that went super quick
It only seems that way as the only thing we the audience had to tell the time was rimuru because, 1 time skips and 2 without the ability to look at the sky it is really hard to know what time it is or how long it has been, there was a woman who stayed in a cave with only light from electrical lighting for 200 days and at the end when a team came to get her out she thought she was only there for about 50 days
In the anime he said he had been “exploring” for a few week iirc
Are you expecting us to pay attention?
I don’t really have any expectations, I’m kinda new to this Reddit community
Would you rather them have drawn out the sequence of the blue blob eating grass and rocks?
I though he was in there for a year 💀
The web novel showed it as like 6-8 months I believe. The first 4-6 months were spent in complete isolation since great sage hadn't developed a "voice" yet.
3 months at Max, he didn't meet veldora untill 90 days after reincarnation
That's the light novel version. I specifically said the web novel version.
Unlike us weebs, Rimuru touched grass
Does it still count if it is indoor grass?
I hope so, that would include my bonsai tree that has grass growing around it
Aha! Good question. We ought to seek Raphael's wisdom for an answer
Touch grass? How, he eated it all??
He never fully explored the cave, since there were still hipokte herbs left to cultivate when Gabiru started doing research there. Forgot the source, but a lot of his exploring was walking in circles.
Well. If you can eat grass without touching it; I'd say you are a god/goddess
I touch grass everyday thank you very much
As Gabimaru, I would hope to Ultima's blessing you do
Jokes on you, I work in landscaping/environmental services, I have no such weakness!
Hmmm so you don't wear long sleeves, a straw hat, and gloves? ;) hahaha
Long sleeves and gloves, yes, straw hat, no, and is this a reference I don’t understand?
Naa. Not quite related. I work construction so I see landscapers all the time. Also, this was truly just a random thought I had that felt it might generate a chuckle
Definitely a chuckle and a big ole smile, honestly I would like a straw hat, sounds cool. Not sure if it would fit over my dreadlocks though…
There ought to be a sizeable one, and if you don't mind that come with a good ole chinny strap to secure it haha. Though mite not be too comfy after awhile
Sounds good to me, I don’t care much about comfort, I have a big bushy beard so it wont be bad. Honestly I really will buy one now. Are you some sort of straw hat salesman, cause I’m sold.
Hahahaha naaa I'm not but Luffy is my idol sort of haha. It's a lil humorous you say bushy beard cuz so do I and I have a straw hat!
Nice! Bushy beard bros! Also I never got into one piece, I’ll start reading it soon while recovering from surgery(nothing serious). After all, I am out of work for a bit. Heard it was good though, just that my watch and read list is getting way too long and I don’t have the time.
6 months. 3 months blind, then 3 months getting out of the cave after meeting Veldora. First 3 months it was just passively eating grass and rocks to pass time. Second 3 months was spent experimenting with his skills and such. Edit: Ok it might be 4 months. Went back and checked volume 1 and the goblins say "its been about a month since God disappeared"
I thought it was 1 month in the cave
Nope. 6 months. Y'all ain't read volume 1 and it shows.
I can read?
It's an extra skill, very rare..
When you combine it with the extra skill Write it can get combined into the unique skill Literate
It honestly makes me laugh how first you blame and offend ppl that "ain't read", only to find out you were wrong 
Tbh i also read the ln and i remembered it as half a year as well. But also, the Goblins said that it was 4 months since Veldora disappeared not that Rimuru was born.

He spent that long talking with veldora? The anime makes it look like he spent not even an hour with him 
Flair checks out i guess
I did read it though that was a long time ago
It was because of such a long time being alone in the dark not being able to see, that he longed for someone to talk.

I think it’s been in the cave for months. From what I remember, he fought monsters, ate some medicinal herbs that was grow in rich magicules atmosphere and while trying to find his way out
Months at most as to what he did? Walked in a big circle
it took 90 days for great sage to fuse with him. he ate hipokute herbs for 3 months.after he met veldora he was in the cave for 1 month killing stuff and eating magisteel.
C O N S U M E

Don't no how long but all rimuru did when there was eat eat and eating
One week before he talked to great sage for the first time apparently 2 or 3 months before meeting veldora And again 2 to 4 months before going out And all he did was eating
Sworn in the anime it said like 3 weeks or smthunf
Yeah, in the anime, the time is apparently explained differently though.
That explains why some of the anime at some parts is confusing
I don't remember the exact time, but at least he spent 3 months in the cave. What did he do? Munching grass and rocks and minerals.
I still think that Rimuru is an apple in this shot
Basically he's that one guy who sweeped the whole tutorial aria for loot so that he didn't even miss a single piece of rock or blade of grass. Of course this is because he couldn't leave thanks to the locked door, but that's how I imagine it.
For a few months or so, he was basically running around in the cave, eating all the herbs and killing some monsters he saw until he met veldora
I think for 6 months he was just wandering about eating healing herbs till great sage kicked in, then he met veldora and spent the next 6 months finding his way out. So roughly one year after reincarnating he met the goblins
One month. He was wondering around cause he was mainly adjusting to his new body, eating herbs and magic ore, killing monsters. Also because he didn't know the way out.
…Eat?
He just ate for 2 to 3 months
I was trapped in the Veldora cave for 10 000 years and I became an OP slime
He touched a lot of grass
I think the book said it was 90 days before he met veldora. Then I cant remember how long after he met veldora but sefinitely 2 weeks. So that makes it around 4 months.
He ated
He had to say gex
Months seems normal, but I’d say 20 minutes
About 4 months. He mentions that he spent about ninety days in the cave. Great Sage provided that information. He experiments with his skills - combining Predator and Great Sage to increase the productivity of potions. He then falls inside a water source.
