After I defeated and devoured the Dragon, my power rose up considerably that I feel like an entirely different person. Probably because I ate both of its heart and soul, I could feel a lot of surplus magic inside me.
I expected something to change after I ate it's heart, but for some reason, there was nothing. Ofelia and Elena simply said that only my life was extended a bit. Since I am already a Progenitor Demon, my lifespan is already around the tens of thousands like theirs. The Dragon heart barely added anything to it.
If I was a human, it would've had a different effect.
"Are you sure this is safe to drink?"
"It's fine, just think it's my blood."
"That doesn't help at all."
"You wanted more power, right? This is it."
"But still..."
Using the power of the Heart, I extracted the dragon heart's essence and turned it into a concentrated liquid and put them on cups and gave it to Delcie, Archie, and Charles.
