After Alosa's explanation about the five major halls, time quickly passed as the sun above the Southern Mountain fell, and the blue sky turned into a fiery orange-red color. As Yoze waited for the tournament to end, he indirectly asked Immortal Patty a few questions he had about the Blue Gem Hall through Alosa.
The first was how and why he was suddenly chosen for this when everyone else in the group hadn't been assigned a Hall to join. The answer he got was quite simple: his performance through the fight with Geo was so impressive that the Head Immortal of the Blue Gem Hall decided to add him to the Hall.
"If everyone else had performed as amazing as you did during your battle, they would have attracted the attention of the Head Immortals as well. But don't get cocky; just because the Head Immortal of the Blue Gem Hall has taken an interest in you doesn't mean you are his student."
