"You can do better than that, don't forget to create bones like ribs on them as your wing's fingers. You need to make them big and long," Eve said as she sat on the rock and stared at Archie.
"I'm trying..." Archie said and then a loud cracking sound came from his back. Both of his scapulas were expanding and then he had to grow bones from his scapulas all the way down to his waist.
Archie tried his best and it was painful because he tore his skin and flesh, and while he was doing that, his tissue wrapped his newly created bones. Eve instructed him how to make wings not using his flesh, skin, or hair, she instructed him to use the parasite inside his body to wrap the bones and tissues on his back.
