The Immortal Queen

There was another lightning bolt forming in the sky. A third Dao lightning was ready to strike down on Scarlet at any moment.

Alex looked to the sky in utter shock. 

Dao was not something that was easily learned by anyone. For a regular person. Learning a single dao was considered amazing. Learning two was considered brilliant. Learning anymore made people think the individual was a heavenly genius.

In Scarlet's case, while she had only technically had 2 Dao Lightnings, the second one was for the True Fire Dao, which meant she had learned enough Fire Dao that she had managed to piece together every other Dao related to Fire and learned the entire concept.

So, in a sense, she hadn't learned one dao, but multiple. As such, Alex had found it acceptable that only two Dao lightning would fall upon her and not more.
