Right after killing the demon, Ray places his hand on the heart of the demon as he pulls out a red crystal and begins to exam it.
"That is the core of the demon, If refined properly it could be very helpful in one's cultivation" said Jenny as she stares at the crystal in Ray's hand.
"How did you know the demon core would be hidden in its heart" asked Ellis.
"I don't know there will be something like this there, all I want to do was pull out its heart but that is when I felt something hard and there you have it" reply Ray as he waves the crystal in front of Ellis.
"Wait a minute, you mean you just wanted to take the demon's heart out" asked Ellis to clarify his thought.
"Yes, that is what I just said" reply Ray quite confused by Ellis.
"What did you want to use the heart for" asked Ellis.
"Nothing, I just felt like pulling it out" reply Ray.
