"… The Staff Stage, the Outline Stage, the Skeleton Stage, the Vein Stage and finally the Wheel Stage."
It wasn't only Ryu's face which became weird after hearing these names, but even the Ancestors looked toward Balaur as though he was losing them a serious amount of face. If it wasn't for the fact they knew for sure that he was one of them, they might really expect that an imposter had snuck in just to make them all lose face.
Unfortunately, the matter only became worse after Balaur explained every stage. It made one feel as though he had created such a powerful technique only to let a toddler name it all for him.
It had to be remembered that names carried power in the world of cultivation. For Balaur to name his things so casually then pass it on to the later generation like this… it was as though he wanted his descendants to remember him by spitting up blood whenever they used his Visualization.
