The Mission: Dagger of Cthulhu! (Ren's mission)

The dragon moves its left wing in front of the sword. Seeing as how its a tiny room the dragon cannot fly. The wing freezes and the dragon burns the wound with fire to cauterize the wound. This would enable limited use of its wing but not permanent dismemberment

Ren seeing a chance to kill the dragon, as it was busy cauterizing the freeze in his winds with his fire, Ren gathered aura in his feet, letting him run with no much trouble on the crystal surface, and as he neared the dragon, close enough to felt the heat of the fire and for an attack, he gathered aura in his hands, conjuring a sphere of aura in his hands, and throw it at the dragon's neck at B-rank speed near point-blank range.

Spoiler:

With its wound finally cauterized the dragon lowers it's wing only to see the sphere already to close to its neck. The dragon knows it has lost and has died with honor. As the sphere hits its neck the dragon dies as its throat is destroyed and i can no longer breathe. Behind the dragon a white outline can be seen as a door opens up. Its a long hallway...

As the dragon dies, he retrieves his sword that was in the dragon's wings, as he sheathed the sword, he look it up to see a long hallway, Ren prepared himself with aura in his feet and make a quick dash at B-rank speed at the hallway, letting his sense of the aura travels in front and behind him, alerting him if there was any trap or problem in here, he din't trust the hallway one bit.

The room was pitch black. You cannot see with your eyes. You perceive with your mind. and thats what Ren was doing he was looking with his eyes. To him the hall seemed endless. He would need to think his hardest to finally understand why the hallway was seemingly unending.

After a minute of continuing running in the hallway, Ren stopped himself and quickly started thinking of why the hallway was so long, after two minute of thinking, he closed his eyes and let his aura and his mind locate the exit of this place, he could feel in his mind that the hallway was dark, not the white hallway he saw early, and this was just a room, not a hallway, it was most likely a Illusion was cast in the room at anyone who entered, as his senses caught the shape of a door, he carefully made his way to it, open it, and entered the next room.

As he entered the final room their was a pedestal and on the pedestal was a book. Behind the book was a man with a cane. "Young whippersnapper your lucky.. You show great wisdom. Read this book and be healthy, Read this book and may your future endeavors benefit you.." The man pointed to the book. Their was no trickery or riddle just simply read the book for it was his reward.

Ren eyed the man with the cane, he chuckled when he called him some thing that every old master always called their student, and approached the book, since he din't detect any malicious intent n the man, he decided to trust the man on his word, and open the book and start reading what was written inside.

As he opened the book it was scribbles but as he flipped the pages his mind would adjust to it. And it all became clear. His mind was progressing. Those in their youth learn as they go on. The book started to glow as all around Ren there were chimes. The scribbles all flowed literally off the page and into his head. The book then slowly started to disappear as it had been done. Ren's intelligence had gone up exponentially. The old man then held out the dagger. Behind the old man a large door opened up and there was a light. It was daylight leading outside. His mission had been completed. wet and burned Ren must have been exhausted but at the same time satisfied with the outcome

Ren took the dagger from the man, thanked from this bizarre little plaything of the mind, he seriously believed he was behind of all this, and made his toward the exit, happy and relieved that he survived all that, and completed the mission.
