Grau was a Giant Dragon that rigidly adhered to its own principles.
David Jones believed that even if Grau wanted to refine Authority after this battle, it would keep its promise.
Besides, times had changed; with Loona's strength progressing, not to mention the revival of Tiamat's will—should the original entity descend—David was confident he could turn Him to dust.
"Good brother!"
Having obtained the Authority, Grau patted David on the shoulder, bid goodbye, and once again rushed toward the Divine Ascension Tower.
Clearly, the long-absent feeling of defeat had ignited Grau's competitive spirit.
Seeing this, Lilith Hoyle and President Will exchanged glances and resumed their challenge of the Divine Ascension Tower.
If even Grau could reach the seventh level, they needed to at least make it to the fifth to be deemed barely qualified.
