What happens when a disorganized biologist gets transported into a different world as a dual serpent.

The other half of the "Twin of the Isles" is contained inside the egg. In the egg's body, a serpent-like beast emerges. The monster is completely different from its counterpart and is shrouded with black scales. The scene fades out to reveal a vast jungle. It all happens very fast. It reminds me of asking my son what he was reading. If I recall right, it was something called isekai.
