"Operator, all request have been accomplished and elixirs are stored in your inner world, may I warn operator that refining and forging cost a ton of mana, I suggest that operator only does this things in safe areas and not during battle since it will result in a huge disadvantage".

When I heard this, I nodded my head and said, "I will keep that in mind, I won't do things without thinking about it".

After saying this, I left the wide space and entered another narrow path once again, I was quite bored and decided to summon Airi, the path was not as narrow as the one earlier so we were able to fit.

On the way I was always teasing airi or fooling around which in result made her quite irritated and went back to her consciousness form.

"Hey airi why don't you come out and stand beside me" I said in a complaining manner, but even still I did not receive any answer.

When I thought that Airi was probably not gonna answer me, I decided to keep quiet and continued walking.

After some time, I saw another exit for the narrow path I was in, I was quite excited to see what was beyond there so I began to run, but upon reaching the exit, I only saw a really wide room, it was around a few kilometers wide.

I looked around the room and noticed that there were some mysterious patterns on the floor,they were like lines that began from the walls going towards the middle of the room and there were atleast around 12 lines like this.

I thought it was quite weird so I followed the pattern. Upon reaching the middle of the room, the weird lines on the floor connected to small hole.

I was really surprised when I saw the shape of the hole, I immediately summond the key I found earlier from my inner world. When the was in my hand, I put the key beside the hole and noticed that it was a perfect fit. I picked up the key and was supposed to put it in, when all of a sudden Airi who was in a consciousness form said,"I won't do that if I were you, you don't even know whats being locked up, and these line patterns on the floor? They are not natural it was placed here as a sealing spell, and not just any ordinary sealing spell but a very high level at that, so I recommend that you don't do anything reckless".

When I heard this, I was startled and could help but look back at the lines on the floor and think to myself,"so this was actually a sealing spell huh? Good thing I acted slowly and did not put it in immediately".

"Hey Airi, what k... Woah!" at this moment before I could even finish speaking, the ground began to tremble violently that it was really hard to keep standing, after which the trembling was followed by a deafening roar.
I was really startle when I heard this roar and thought to myself,"what kind of animal could let out such a load roar?! No animal could even match that kind of roar in my place!".

After a few moments, I began to get nervous, that is because light began flashing in front of me. I began to walk bsck slowly, but before I could even get that far, another load roar resound which made the ground tremble once again. I fell unto my butt and tried to stand up, but just when I stood up, I heard a voice from behind me,"Who is it that has come?!".
