Eren's sharp nails stabbed through Yevni's chest, almost gripping her heart. Just a little pull, and he could claw her heart out of her chest.
He didn't care if the person in front of him was a man or a woman. There was no gentleness in his eyes. For now, he only cared about his own safety.
If she doesn't ensure his safety, then he could only take more drastic steps, which he wanted to avoid.
He was slightly curious to see if he could take Yevni's bloodline with Devourer, or if that skill didn't work on beings of hell, just like his destiny physique didn't.
For the time being, keeping her alive was more important so he didn't claw her heart out. She was his ticket out of this place. He couldn't hurt her yet.
"If you kill me, you can't leave this place alive either."
Yevni used her other hand, stabbing her claws in Eren's guts. Instead of freeing herself, she tried to hurt him even more, knowing that he couldn't kill her.
