Eren cautiously continued his exploration of the dragon's body.
The insides of the dragon were very similar to the Sea Serpent, but it was also very different. He didn't know what it was, but he felt like he was suffocating the longer he stayed inside.
As he went deeper, Eren's eyes caught sight of the Sea Dragon's heart. His heart was smaller than the Sea Serpent's heart. It was so small that it was no different in size than a human's heart.
Despite its small size, it was still brimming with unknown bloodline power.
"This small thing is a Dragon's heart? Is this why they are able to transform into a human form easily?"
He reached out his hand and grabbed the Sea Dragon's heart. Like a fruit from a tree, he plucked the heart.
Instead of eating the heart right here, he made his way back. He didn't like this disgusting feeling inside the Sea Dragon's body.
