True Time

Alex knew of a few types of Time Aura. He didn't know it, only knew of it. 

Having an Aunt whose entire physique made her the greatest person at understanding Time by default was quite helpful in learning a bit more about Time.

There were a few different Daos of time.

There was the regular Time Dao, the Dao of Temporal Stagnation, the Dao of Temporal Swiftness, the Dao of Temporal Stillness, and the Dao of Temporal Reversal.

Those were the Daos his Aunt had learned even before she had left the lower realm. 

And if nothing, at the very least, Alex could tell that these were none of those aura. This was something entirely different that he had to figure out.

And that was going to take some time.

He stayed in the same spot for hours, and even as night fell, he remained still, understanding what the aura was about.
