Dangerous Training

I went back to the human world. I had to get even stronger if I wanted to destroy all the enemies that I seemed to be making. I needed to find a secret place to train, so I started my search at all the abandoned places of Karakura Town. I tried the abandoned hospital and junkyard, but those didn't strike my interest. I went to the old train station, and felt something very strange about it. I started walking in the direction of the feeling. I passed through the station and came to a huge door. It was hidden from view and I don't think even I could have found it if not for the strange feeling. I opened the door and went inside.

I started walking down a dark tunnel. It seemed to go on forever, and was really annoying me. I kept walking. There were multiple turns and plenty of times that I had to decide between split paths, but that spiritual feeling showed me the way. Pretty soon I reached the light at the end of the tunnel. I walked into it, and I was automatically awed at what I saw. It was a huge cavern with a large lake. The cavern seemed to be entirely made of diamonds. The walls, floor, and ceiling was all diamond. They sparkled and gleamed. There were huge stalagmites all over the place. The only problem was that these stalagmites weren't diamond. They were metal. I approached one of them and studied it. These weren't just any old metal. These were adamantium. Adamantium was the strongest and most powerful metal in the world. This would make for excellent training. I looked all around the cavern and smiled a devilish smile. I will become the most powerful Shinigami.

Before I could start training, I had to make sure that nobody could find this cavern. The funny thing about this cavern was that it was filled with reiryoku. I could feel it filling me up with power. I had to figure out how to hide this place from everybody. I walked back out of the cavern and went through the tunnel. I now knew how to navigate easily through the tunnels and pretty soon I was back at the door. I left and all of a sudden I couldn't sense it no more. I turned around and the door was gone as well. I knew that the door was there, but I couldn't see it. I guess I didn't have to figure out how to hide it.

I walked back into the cavern and sat on a flat stalagmite. I thought about how I could begin my training. I could practice my Hakuda. Punching and kicking the adamantium stalagmites would most certainly increase my hitting power. I could also practice landing more hits so that I could inflict more damage. I looked for a good group of stalagmites to practice on. I found a group of 3 stalagmites in a triangle. I walked over to the triangle and took up an offensive stance.
Ready! Set! GOO!

I was about to land a hit on the 1st stalagmite when a thought crossed my mind.
I should tell Dami about this place first.
I decided to postpone my training, and left my cavern. I opened a Senkaimon and went back to Soul Society. I could sense his reiatsu and it seemed like he was either sparring or in battle. I rushed to where it was coming from. My shunpo had definitely gotten faster. I reached the outlands of the Rukongai and walked the rest of the way.
