Was the target demon historical level or legendary? For Wu Ya and the others, the matter wasn't all that significant.
Having the ability to call on two historical-level reinforcements meant they could at least get one legendary-level ally, especially since Ji Tianqi was himself a legendary superpower user/Martial Arts expert.
The real problem was that the sea snake had evolved into a demon, which seemed to have a certain connection to the Divine Dragon. Yet this creature, that anyone could tell was a species of sea turtle, was supposed to resemble a dragon...
It didn't look remotely like a Divine Dragon.
[I'm only thinking this, I didn't say it out loud. Do I really have the superpower of a jinx?]
An anxious Wu Ya tried to sound calm in the underground command center of Film and Television City, "It's okay, Mr. Ji has self-awareness correction. We've prepared the scene and props for him, he will see the turtle as the Divine Dragon."
