If the Evil Dragon didn't self-destruct, who would have thought its whelp would be an Amethyst Young Dragon?
Probably all the Pureblood Dragons on Dragon Island would instinctively assume that the Black Dragon's whelp was a Black Dragon Whelp.
Speaking of which, how did the Evil Dragon know that Dragon Island was about to appear?
Even Thunder Dragon Erinna didn't know when Dragon Island would appear, so how did he know?
By guessing?
It's probably better if Dragon Island doesn't show up, as its appearance wouldn't be too friendly to the Evil Dragon and not too friendly to her as a fake young dragon either.
It would be best if it appeared in a few hundred years because by then, the Evil Dragon might have already buried her in the ground.
She's not a powerful transcendental being, nor is she a real Amethyst Young Dragon, and won't live for long.
"How do you know Dragon Island is about to appear?"
