Keep reviews civil, please.

Well that was an uneventful ten levels into the Orcus Labyrinth, now the only thing that I was very disappointed was several minor things, first, I didn't bring enough food to feed all these people, secondly, I got to keep none of the gems I managed to collect, I honestly wanted to experiment with the blast gems, and the green light gems more to find more uses for them.

The innkeeper told me that it was a fire hazard that he simply would not allow, so he pretty much gave me a choice sell them or sleep outside, I got a decent price for them that is true, but it did put a bit of a hamper on my experiments. The fool doesn't realize that said experiments could help many to better protect themselves, or make life easier, but what can I possibly expect?

Third since I didn't have enough metals or gems I couldn't work on my experimental storage ring, I managed to make a single one thanks to the spare gems the castle blacksmith just left lying around, at most I can store up to two months of food for my self thanks to how convenient my emergency rations are.

But I really need to put it to the test before I can actually put some food in my ring. Inorganic materials didn't take much space, food and other organic materials did, I need to work on this, guess I should really consider taking an extra backpack with me, and keep only one month's worth of emergency rations, the rest I can use the space for bandages, some monster replants I bought thanks to the money I got from selling my gems.

You really can't take a situation for granted and I needed to be careful, miners know more about making monsters think twice about eating a person, than people give them credit, and those in this city know it better than anyone.

As I walked to back to my room I saw a light as if someone was waiting for me, just as I walk into the room I saw Kaori wearing what would be her sleepwear, her silk sleepwear that left very little to the imagination, I mean I never would have thought Kaori to be this forward, waiting for me sitting on my bed wearing this?

I mean I have seen this sort of thing while going through the clothing catalog that my mom and her friends ordered, but I never thought I would ever see one of my classmates wear something like this.

Something must really be bothering her to be waiting for me this late.

"Kaori I must say that color really does go well with your eyes, and you look lovely this evening, but I must ask are you alright? Something tells me that you wouldn't wait for me unless something is causing you some trouble." She smiled and stood up in such a way that I unintentionally ended up looking at her cleavage.

"Or maybe I came in here to sleep with you Hajime, but you are correct I just had a vision of what could happen tomorrow, I saw that something bad happens and that you don't make it back with us. You were always able to tell when I was feeling bad, or worried, so is there any way you can stay out of the labyrinth tomorrow?"

I looked at her and smiled, so she waited because she is worried about me, "If something bad is going to happen as in your vision I have to go now more than ever if only to keep the rest of you safe, don't worry Kaori, I am taking every possible precaution, and I will do my best to help you and the others, after all, how much danger would I face way in the back, since I am a synergist."

She finally seemed to relax and left my room, I could now go to sleep, all because of one nightmare, she became frightened over one nightmare, I will never understand why does Kaori follow me around back when we were training, why did she always seem to also follow me ever since before high school now that I think of it.

There are many young men and women who probably wonder this very same thing, I am not what you call the most handsome guy in our class, in fact, the least popular, even in my own guild yes they were sociable, but I could count my true friends in the guild with the fingers on one of my hands.

So why is Kaori so concerned with me, so much so that she came straight from her bed to warn me of what she saw in her dream? Never mind, I have to sleep to be ready for tomorrow's exploration of the labyrinth, really a dungeon, but why bother with semantics when I am so sleepy.

I went to sleep and had a peaceful night, nobody bothered me, except for the fact that I had a very small dinner. Early in the morning I woke up and went to try and have some breakfast, and again the ever considerate classmates ate most of the food on the buffet and so I had another small meal for my breakfast. I am beginning to suspect they are doing this on purpose.

"Good morning Meld, I hope you had a restful evening." He looked at me and smiled, "Yes I did, thank you, not as restful as some of your friends suspect you did, apparently one of the lady heroes went to visit you late in the evening, some might even say that you two spent the night together. While you two are adult, I do hope you consider the effects of having a child would cause your group of heroes and our nation."

So the idiots think Kaori and I screwed like a pair of animals in heat, last night, the only thing that happened was that I tried to calm a very worried and frightened Kaori after she apparently woke from having a nightmare. "Actually she did visit me, but in reality, it was about the trouble I nearly caused by trying to experiment on the gems I brought back with me, and she also mentioned that I might need to take more food with me since the deeper we go the tougher the monsters we would find."

Meld actually smiled when he heard me, "That is very reasonable, I shall have to thank you and her for thinking ahead, and yes blast gems could have caused the entire Inn to come crashing down on us in flames, those gems while very interesting for synergists, I have to say they are also very dangerous and must be handled with care. I should have told you about that."

The trip was nothing out of the ordinary, except for the feeling that we were in a parade more than anything, since people were watching us go towards the entrance to the labyrinth or the mine, of the dungeon depending on who you might ask.

The place had a convenient transport spell network system, every ten floors there was a teleport glyph carved on the floor at the beginning of that level, and anyone who managed to get to it could use it as a means to travel from one floor to the next. If this was a gate I would say it has a quick travel feature.

One-touch from Meld and every one of us was right back at the beginning of floor ten, well that certainly saved us a lot of time. The only bad thing is that only high ranking members of the knights or the miners guild knew how to use the glyph anyone that did try to use it without the knowledge could end up in a place they could later regret.

So we fought the usual monsters, or should I say I built barriers and pitfalls to help the others fight the monsters and it was pretty much a routine by then thanks to what we did yesterday, we got used to doing this rather quickly now that I think of it.

The one thing that amazes me is that this place never runs out of monsters, there must be something in these places that keep replenishing the monster population, they regenerate, or there some female monsters really ticked off that they have to breed like there is no tomorrow. The one thing that makes me think they actually re-spawn is that this is the second time we fought the same floor bosses, and they remember us.

How can I tell they remember us their angry glares and growls pretty much tell me these creatures remember exactly what he did to them the last time we met. Then floors and half of my backpack rations are gone, these guys may not look it but they sure eat and drink an awful lot more than most people would think.

I just gave them enough food to feed a battalion of knights and they are still complaining that they wanted more. Well we kept fighting I kept collecting gems, and then we reached the twentieth floor, which to me would mean that we get to go back to the Inn, and I get to go back to the kitchen.

Not that we had any other choice, my backpack is empty, I still have that month's worth of rations in my experimental storage ring, but I rather test if it works and not risk them getting sick if my experiment turns out to be a failure. "Oh, pretty." That made me look at what Kaori was looking at.

Several of the ladies in my class seem to also find that strange crystal growth to be rather attractive or simply beautiful. "Oh, those crystals, well ladies I am not surprised you like them, you know that these crystals are primarily used for engagement rings." This made them all start blushing, damn it, I wish Meld had kept that information after we were at the Inn.

Daisuke being the idiot that he is beginning to climb towards it, "Daisuke gets back here, we don't have time to grab those gemstones now. I got a very bad feeling about this, they were not present on the previous floors, this is giving me a very bad vibe."

He looked at me with this smug look, "I always knew you were a coward Hajime, just you wait, I am going to make the single most beautiful engagement ring she is bound to finally notice me, instead of always, and I mean always paying attention to a worthless piece of garbage like you!"

Damn it Daisuke this is not the time for some hormonally driven feeling of rivalry, we could die in this place if we are not careful. He touched and sure enough, the flash of light told me the crystals actually were an illusion, what they were really looking at was a spell that has been forced into some ordinary green gems.

As we open our eyes from the incredibly bright light that nearly blinded us when the spell activated, I immediately looked at my status plate and touched the map function, oh great, congratulation folks. Thanks to some idiot's greed we got transported twenty-five floors down in the dungeon.

"You might not want to look at your status plates, but according to what I read, we are currently in the sixty-fifth floor, that pretty cluster of crystals was a trap. So Meld, do you know how we get up to the surface from here?"

Boy for a hero he sure is dense sometimes, "Sadly no, no one has ever reached this deep before, we really need to be careful, we really need to find that teleport spell so that we can return to the surface, but we really need to be careful. These monsters will be a whole lot tougher than the ones you normally faced."

Why is Meld saying things that will make these idiots think it is a challenge to their manhood? "Challenging for you, not for me and my friends here, we are heroes, we don't cower or run away from anything, these monsters should run away from us. Come on guys or you will end up being as much of a coward as Hajime is. Chicks don't like cowards!"

The began to run recklessly across the floor of the dungeon and that is when we found a rather sturdy looking stone bridge, and wouldn't you know it, the teleportation rune was just across it. "Guys I think we should listen to Meld and be really careful here, you don't know what we are up against."

Daisuke and several of his band of bullies looked at me, "See what I mean, Hajime is a worthless coward, a pathetic wretch no matter what world we are in, he was pathetic in our world and wouldn't you know it, he is just as worthless here. Why don't you do me and my friends the favor and fucking die already."

As he said this he and his friends stepped on the middle of the bridge, and that is when a massive magic circle appeared, from the mass that was coming from the bridge and slowly building into a monster I could tell what the hell we were looking at, they might not read this world's books but I did. The look on Meld's face told me he could tell exactly what we were going to have to fight as much as I could.

The creature looked like a giant earth dragon with steel for scares, and enough muscles to make the monster from the movie Pacific Rift look meek by comparison. "May Ehit have mercy on us, that is a Behemoth. Alright, people, some of us will distract it while the others run towards the teleport point and get the hell out of here."

I tried my best to form barriers for people to hide behind and let them have a chance at Kaori healing them, I made a pit big enough in the bridge that it could immobilize the giant beast, but that was not enough to keep everyone safe, as more of our classmates made it across to the place where Meld would help them return to the exit of this place I saw that this thing was actually toying with us.

I threw caution to the wind and began to draw his attention to give my classmates a much better chance, I even threw my backpack at it which was full of blast gems, which of course when it hit the back of the monster caused a spark and cause the entire backpack to explode like a bomb.

This didn't do much to the body of the monster, it did, however, make him furious and came towards me, that is when the few that learned to use magic sent their most powerful spells at it, one sent an army of undead skeletons to keep the behemoth busy, and that is when I saw them send dozens of fireball spells at it, except that one hit the area near me and cause the area under me to collapse, last thing I knew I was falling I don't know for how long, all I know that if I hadn't landed in that small pond of holy water, that ambrosia saved my life, this water came from mana that crystallizes and forms orbs, over time they dissolve and form this liquid that saved my life.

This holy water is said to heal any injury no matter how severe, or how lethal the condition is. I apparently fell five floors straight down, I somehow don't think this was an accident if my experience of being bullied taught me anything is that this could have been done intentionally to kill me.

They may be my college classmates, but that doesn't mean I got along with all of them. Daisuke and his gang of thugs were a constant source of pain and trouble for me, to say that the band made my school life all the way from elementary school a living hell would an absolute understatement.

I could never understand why Daisuke seemed to take this perverse pleasure at making me suffer, I lost count how many times he did something that ended up either with me getting punished or blamed for something I never did.

Well it looks like this ring experiment was not a total success, but also not a total failure, it did preserve my food, just that it didn't preserve it warm, so the food is safe to eat it is just really, really cold, taking it out of a fridge cold, but it seems it at least give me one month to find my way of this place.

I got no means to defend myself, and not exactly what you call strong enough to take monsters head-on, at most I could make pitfalls but even those will not keep the more agile or skilled monsters trapped for long. I better take this situation with caution, unlike my fellow classmates may think they are in a game, I know better.

Well, my clothes are pretty much rags, I guess falling down from that height, I should be happy that I am alive at all, and not worry about the condition of these clothes. Well, I don't know if by misfortune or luck but the area around me was heavy on green gems, blast gems and the toughest metal that I ever have seen.

Well, it seems I can't go that far into the floor since I could practically feel the killer intent all around me. I had better complete the experiments on weapons now that I have plenty of resources and nothing but time to perfect this. I think at most I should be able to create the equivalent to dynamite.

I can't make it work I have to inscribe on each stick for it to work and it would take far too long for me to replenish the ones I use. I have been down here for three weeks and I have a few dozen of these sticks left, and not much more material to inscribe with. I kept thinking of the question of who could have betrayed me?

No matter how much I think of it, I honestly think it was my main tormentor Daisuke, he has a great enough control of fire magic to be able to do it, and get away with it. He is often mean, but when Kaori is near and tried to help me he becomes vicious. I will never understand that guy, but I know his hatred of me must run deep for him to do this to me.

All alone surrounded by man-eating monsters, had I not figured a way to create holy water I would have not been able to heal when away from the mana orb. I have enough food for one more week, this holy water is great for healing illnesses and injuries, but does nothing about hunger.

If the situation continues and I am unable to advance, I might have to consider eating monster meat, even if every text I ever read said that is suicide. Monsters can manipulate mana freely, since the day they are born they have mana crystals that flow throughout their bodies. Those same mana crystals are sad to destroy anyone that dares to eat monster meat.

I am running low on food, and still on the fiftieth floor, it may come a time that hunger will make me do something others consider suicide, but I must survive, I will never get the answer to my question unless I manage to see that guy face to face and ask him why did he try so hard to cause my death? Maybe Hiro will know but he is always so frosty with me, what did I ever do to tick that guy off this much?
