A Space Temple Chief
Yang Lujia and the rest of his company explored the territory of the Fiend Emperor Palace after getting all the things settled in the Dragon Emperor Palace. While Long Guang was technically still the Dragon Son, the Dragon Ancestor that he wouldn't be able to rope in this monster with them. Therefore, he let him go with his master who was a monster as well in his perspective.
If his son would wake up soon, he would tell him this sad truth. After all, from the way Long Guang reacted when his son got bedridden, it seemed like he really cared about the latter. Regardless, someone as talented as that kid—would not fare any better if he'd choose to isolate his talent in a meager place like their palace.
If a native of Da Shikong heard what the Dragon Ancestor was thinking, they would probably be shocked. After all, the Dragon Emperor Palace was a revered existence in the whole of Da Shikong, only second to the two temples that were considered superior among all.
