The Yin Fish Boy spread his hands showing he didn't understand, "What do you mean by spinning and spinning?"
The Yang Fish Boy explained, "What he means is, this 'non-thing' and the evil energy form a model similar to a tropical cyclone, with a concentrated vortex area inside called the vortex core, where its movement is similar to rigid body rotation. Outside it, the circular speed of the fluid is inversely proportional to the radius; inside, it is directly proportional to the radius, with the circular speed being zero at the vortex center.
So the core of the gaseous 'non-thing' is likely in the vortex core area, manipulated by Canglong and bound with the evil energy, so only a small part can escape through the vortex center, forming 'Yang Ying's' form."
Li Fan, "…Yes, that's exactly what I mean!"
The Yin Fish Boy then squinted at him sideways.
