Elixir of life?

Lately I've been injecting the blood of the coreun into a mouse to see what would happen, I didn't notice the results until when I accidentally penetrated the needle through the mouse. It seems the blood of the coreun contains some kind of substance that can make wounds heal at a insanely fast speed. No matter how I try to scar the creature, it'll always recover to the state like nothing happened. Though, It's not impossible to kill it, decapitation will kill it before it can regenerate anything.

I think it's time to take the experiments to the next level.
