"Are you saying you'll teleport every single Hashira and Shira inside this hidden underground land, ÆShin?" Rigakure questioned, turning around menacingly and glaring at him.
"Yes, is there a problem with that? Maybe it's time to introduce this magnificent place to all of the Hashiras and Shiras, we were all talking to each other lately in the spirit dimension, it didn't take that long... One of the Hashira's of the north wind doesn't have its mouth, but we're all sure he did the job done," Fukeshin Gakure replied, making him glare even more and see he's furious. 
"I won't let you teleport every single one of them here... And there's one more Fukeshin Gakure and Kiroshuku Hakure, that's a spirit realm you're talking about... The spirit dimension is a real thing where every swordsman's spirit is there, you're talking in a different place. That place is where every Hashira and Shira can talk even if they're far away, I was invited in there to get in late, in fact, I was there, I looked for that Hashira and the only thing I found was his blade and sword guard and a warp dark portal, I didn't manage to get inside of it which bothers me that a new being is made by the Dark God himself and for your information, he knows about this hidden underground land. I'm not sure why he's sending such weaklings around it; I killed every single one of them, and I believe they're looking for the entrances," Kage Rigakure stated solemnly as he gazed up. 
The ground underneath them began to tremble once more. But it abruptly stopped, leaving them silent for some time. They were amazed and impressed that there were no cracks in the ground or the ceiling.
"Good thing we're wearing our coats, huh... It's so cold, I can't believe it, I thought it would be some kind of hot area... And I know you already said it's because of these giant trees, and there's light... Where's this light coming from, Kage Rigakure?" Kiroshuku Hakure asked as they looked up at the ceiling. 
"It was magic. It could light up every nook of this land. There were a cluster of grasses in the ground over there in the distance... This place is at peace and ease, the light was hidden to avoid it from being destroyed... I'd heard its source was the sun, but it was also a mystery how it was formed, but who cares? At least this vast cave has light, and it's deep underground. I believe it's simply a few thousand feet. I can light up this Hidden Underground Land by myself if I want to, so look at you two! Also, Fukeshin Gakure, you may transport them here, and we'll all talk here. I have something to say to all the Hashiras and Shiras if they're all present. I know the plan is to leave two Hashiras in each village, things are about to get out of hand and exciting," Kage Rigakure replied, smiling and laughing. 
They arrive at at the bottom ground after a few minutes of going down the trail. They came reached the flat grassy land in a patterned trail. The three of them can see the massive apple trees, as well as other trees and excellent crops. There were many plants there, as well as others in the distance. The plants were overgrown, revealing how huge it is, as well as the massive mansions that surrounded the massive trees.
"Those houses were abandoned, there was a river here and a bridge, the water was clean and there were healthy fishes, and this massive land is at least seven hundred feet tall and the same as those massive trees and probably more. Aren't those mind-boggling? The light encourages crop growth and wellness, the sorcerer lives here in the past, and I'm one of them... I am the last of the Rigakure clan. My clan was a hidden clan amongst many others. There were more than twenty hidden clans in total. They can change the direction of the wind, and if these clans ever clashed, our planet. would be devastated and turned into a wasteland," Kage Rigakure said as he sat down on the grass and looked around. 
"You can go for a walk... The others are fighting on the surface, just tell me, I'll teleport you both in and out here, I can teleport to every village I want if my marks are still there, if they aren't there, then I can't teleport to that specific place, a lot is hidden and more powerful enemies are yet to come to Fukeshin Gakure and Kiroshuku Hakure, those enemies that you fought were weaker, should both fear the Dark Undead soldiers of the Dark King, he was the Dark God's right hand... His left hand was his son, and his son had a human body, it was a stolen body," he added solemnly as he lay down on the ground. 
Fukeshin Gakure and Kiroshuku Hakure gazed around. Except for the breeze made by the gigantic trees above them, all was silence. The gigantic trees were blowing each other and twirling all around the unseen beneath world.  
"Which body, who's that body that the Dark God son stole?" Fukeshin Gakure inquired as he began to walk to his right. Kiroshuku Hakure did not follow him from behind, but instead moved to his left. Kage Rigakure took a step back, looked at them both, and chuckled. 
"Fukeshin Gakure, it was that swordsman who made the Dark God kneel, that swordsman died of old age and died standing, death can't even make him go down to his knees, and then his son takes over that man's body and brings it back to the teenager version, past Hashira's belief that he's more powerful than the Dark God and then that swordsman, but he wasn't... He needs to improve and learn how to use his abilities, or that body will devour him alive. He can't keep it up, so he has to abandon it... But he conceals that body and assumes a new one... And that body belonged to the swordsman who forced the Dark God to kneel before him. There were hundreds of swordsmen who will carry on his heritage, they are now known as legends who will carry on his legacy, but that man was more than just a legend himself, he made them all shiver and kneel merely glaring and standing in the distance. He defeated a thousand Dark mobs and hundreds of Dark Shira Swordsmen alone in a dimension, someone said he was near the Dark Fortress, the source of their power, but he wasn't," he replied solemnly as he sighs and raises his head, looking up in the giant massive trees as he heard a massive blow on the surface that forced him to wear his mask. 
"What do you mean by that?... That man is supposed to be in there, right? If he wasn't there, then where were he and the Dark God? Where are they both? Isn't that the Dark Fortress Dark God hideout?" Kiroshuku Hakure asked as he turned around and saw him looking up and wearing his mask.
"That's where you're mistaken, Kiroshuku. The Dark God was not in the Dark Fortress, he was in another world or planet like the one we're standing on, with his Darks, that swordsman arrived just in time and saved countless Hashira's, there were countless powerful Hashira's in the past, they were all enhanced because of him. He stands before them and fights before them, but at first, that swordsman is just in a different league than any of them, they can solo those countless Hashira's but don't underestimate those Hashira's, they were more powerful than us and that legendary swordsman was powerful than them or us, he was not old in that time and in that time was the Dark God escape because of the Dark King that manages to keep up with his moves with just instinct and luck, then after that. He didn't manage to kill the Dark King because it could warp itself in or out of a portal, which enraged him, but it was too late, the planet they were standing on began to rumble and the core began to eat the entire planet alive, all the Hashira's survived because of him, and the entire world became at peace, it was our world. He teleported every Hashira there, some of them utilized warp portal, he was meant to be there but he wasn't, he vanished without a trace, suddenly someone appears, a new adversary," Kage Rigakure replied calmly.
"Our conversation is starting to get long and long... Because it's the past, we can't make it shorter, we need to make it detailed to know what happened in the past and that could help us, taking this to the Hashira's would be pointless since they're not here to chat," Fukeshin Gakure replied, making Kage Rigakure laugh and sit down again on the grass.
"Yeah, I can't just make it detailed, I need to show it and show my color to the current time, you are both near my age, HAHAHA! I couldn't stop laughing and giggling. I hope you both still have those skills and experience... Things are about to get real, I can sense... Someone warped on the surface and it's powerful near the Dark King Level... I'm curious who he is, he just plowed into the surface, and I realized a floating island to the north... I'm not sure what it is or where it came from. If it's a hidden land or a floating island, there should be a Guard Hashira nearby," he added, drawing a glare from Fukeshin Gakure. 
"Yes, there was a floating island... I believe it's near the north, the enemy was also dark and then Katrina and Rengoku fought this unknown for some time. It was a crystal Blade user, different than the others. When they fought it, it started to get real. Rengoku said a lot of things when we were on top of the giant wall watching Hanako talking to Dark and waiting for Katrina Rengoku to arrive. After that, I was confused and had no clue where that floating island came from. In fact, it's near the far north," Fukeshin Gakure replied as they looked at each other curiously. 
"Near the far north and the north?... Well, we don't mess with distant regions. I hate those Hashira's, and about Hanako, she will encounter the consequences of betraying us, or I'd say humans... She might be a new Dark Being, since she has dark energy flowing inside her. I've never seen any human obtain such a thing but it's a rare case... She can control it," Kage Rigakure said, which made him close his eyes and sigh. 
"What do you mean in rare cases? Does that mean anything? Are you saying that there was someone in the past who managed to obtain the power of the dark? Meaningly... There were more than just traitors in the past, haha! Mind telling us who they are and what kind of being are they now?" Fukeshin Gakure asked as he giggled.
Kage Rigakure suddenly turns to face him. For a little while, he appeared unfazed as he slowly stood and began to go to his right, towards Fukeshin Gakure. 
"Those traitors... I'll never forgive them. They're the ones who betrayed the previous heads and killed every last member of my clan. If you find one of them, tell me. I want their heads or their heads off their bodies, Fukeshin Gakure. They've been living for more than a decade, they're part of an army, the army of the Dark King, and there's a total of six of them... If they're here, I'll gladly leave this hidden beneath land," Kage Rigakure replied menacingly as he strolled by Fukeshin Gakure, making Fukeshin Gakure sweat and shudder for a minute as he exhales and inhales.
"About Hanako's consequences, will she be sentenced to death or sent to another distant continent with unknowns... And with a Hashira?... I heard there's more than one Hashira, there must be a Traveler Hashira, isn't that right, Kage Rigakure? As the last of Rigakure, you can tell us everything you know from the past that is still happening now, you know there's a world, dimensions, and more things that we don't know and can't handle, but we can assure you that we can handle it and pass information on to the right person, Kage Rigakure... It's time you got some fresh air outside and not in this cave, you've been living here for too long, and we both feel horrible for you. Shimodo Rou's father was a brilliant man in his era, but none of his swordsmen or swordswoman liked it, since the way things transpired ended badly, he had a wonderful start but a poor ending, his reputation was shattered, and it turned into a tragedy that led to his death... Suicide, he died as a result of suicide, and is this the work of a Hashira? Who is the traitor? Are you one of the unknowns? In the past, were you one of the Dark New Beings? We don't get these Dark Beings from the past, they emerge out of nowhere, as if someone is observing us, this is reality. Kage Rigakure, even after the surface, all of the surfaces above you, have been vanquished, are you still going to sit here and do nothing? You know they'll find this place and turn it into ruins," Kiroshuku Hakure remarked menacingly, prompting him to turn around and glare at Kiroshuku Hakure.
"You have no idea about the past... You were all young while we fought in the shadows. There were just hundreds of these in the past. This massive hidden underground land, there were hundreds of these. It was gifted to us, it was an ancient land, and my ancestors made incredible foundations so that the ceilings wouldn't just fall and I was here and I could make things right whenever I wanted. I was watching everyone... I'm sophisticated, I can envision a result. I've previously led an army as General Hashira... But, looking at the Generals now, they're nowhere near the level of a special swordsman! This era has grown weak! And if this is the end of the world, I'll accept it! When the Swordsman's Era ends, there will be no more, and there may be no humans left. You both remember what I said, right? The legendary swordsman who was once described as a prime example of talent. He once declared he would be reborn... But I don't think it's in this Era, Kuro has been captured and imprisoned in a dimension, and Kenki and Katsuki will soon vanish if they made a mistake, I'm just grateful to the current Shadow Guard Swordsmen and the current heads who lead the villages, they'll make a good new Era for Swordsman's. Near the North Wind, there was a swordswoman. Find her and hope she's still alive or you can find her when you teleport everyone in this place. Be careful on your way up. Things are starting to get out of hand when you teleport them here, there could be trouble," Kage Rigakure said as he bowed and kneeled. He tears out behind the mask and showed a bright glowing left eye. He stared at them both as suddenly Fukeshin Gakure and Kiroshuku Hakure had both eyes closed. 
Within the spirit realm. Kiroshuku Hakure and Fukeshin Gakure were present, as were several unknown Hashiras and Shiras. He was standing next to him. They were standing next to each other.
They can see one unknown swordsman in the distance, who is accompanied by two additional unknown Shadow Hashiras and two Shadow Guard Swordsmen. 
"Fukeshin Gakure! There will be sixty Shiras and seven Hashiras joining us. I hope you're ready and have already prepared a spot for all of us," Kataku Sukure exclaims as Fukeshin Gakure and Kiroshuku Hakure begin to approach him. 
The Hashiras and Shiras move to make room for them both. Everyone respected one another, and they were all dead serious and suited up. ÆKenki and ÆKatsuki stood nearby, watching them. They will not be teleported unless they expressly request it. 
"We will teleport you all here to my spot! This is a hidden underground land being guarded by a Shadow Guard Hashira! It was far beneath the North Wind... This Hashira is trustworthy, he was with Shimodo Rou's father, and he was one of the foundations in the past, more dangers have arrived on the surface, and all-out war will occur, and Shira's may perish in the battle! Be wary of the Dark King's army, soldiers, and swordsmen! Everyone needs to band together and annihilate them right now, no one should perish! Everything will finally come to an end there! We have masters on our side, and a slew of Hashiras will assist! Prepare yourself!" Fukeshin Gakure exclaims as he turns around, both of his palms lighting up. 
They all vanished in a blink of an eye and a large area where Fukeshin Gakure is standing is lit up. In the Hidden underground land, Fukeshin Gakure was kneeling and had both of his palms touching each other and there was light surrounding him. Kiroshuku Hakure and Kage Rigakure were a distance away from him. 
It suddenly glowed brightly. Unknowns began to materialize and teleport. Unknown faces and swordsmen in masks began to show up. They were shadows and ghosts for a split second before becoming fully human. 
Fukeshin Gakure takes a deep breath as he kneels. With both of their hands, the Shiras were assisting him in breathing and standing. Three Shiras assisted him while the other Hashiras and Shiras glanced up, shocked that he was telling the truth. They were transfixed as they looked at Kage Rigakure. 
"Welcome! This is the Hidden Underground Land! Guard me! Kage Rigakure! A Shadow Guard Hashira Swordsman! This is forbidden underground land and I was ordered to guard this place for the rest of my life! The surface was more than just thousands of feet above us, the trees were more than just seven hundred feet tall! Don't cut anything, but you can grab herbs and leaves if you want. Just don't destroy stuff or I'll cut that man myself! Now! Hashira's! You'll be fighting the Dark King, swordsmans! Get ready for a fight that you won't expect!" Kage Rigakure said, which gave them goosebumps. He said it menacingly made everyone in there smile and heat up. Their tremendous aura was showing and they all looked menacing. Kataku Sukure and the other two Hashira that were with him began to walk towards Kage Rigakure.
