The Construct 

I looked at the Rhino-humanoid from top to bottom. From its sharp horn to intricate armor to a huge sword that is bigger than itself.

I didn't have to think too hard to know what this challenge was, but I was barely able to focus on it when I noticed the door, with 'Exit' written on top of it.

'There is an exit,' I thought.

I have no plan to exit, but I hope, that there is something in there to keep me here. Crystal box looks good, I wonder, what kind of reward it has.

I thought for a second before shaking my head and focusing on the opponent in front of me. I have read the rules and I have to defeat them, but if previous challenges were any proof, it wouldn't be easy.

Still, I am willing to give my all and I could. 

Aside from the ability to bring things out of my core and the storage, I could use everything I have. Including the clones, but I wouldn't be using them.
