Xu Qing left a Demon King Protector to guard the altar, while his true self took the corpse and scepter of the Qionggang Ancestor, along with the looted materials, back to the Great Yu Dynasty.
This journey to the Otherworld yielded great rewards and opened the Otherworld commerce route for the Great Yu Immortal Dynasty. No matter how you look at it, it's a prime example of a major win.
The only concern is not knowing when it will attract the attention of a Great Witch from the Jiuli Tribe Alliance.
Fortunately, according to the feedback from the bronze mirror, the Great Yu Immortal Dynasty's Jiazi Catastrophe has shown no anomalies, and its timing has not changed.
From this reaction, it seems they are temporarily safe.
If the Jiazi Catastrophe were to be hastened, Xu Qing could only resort to emergency evacuation and destroy the Five-Colored Altar.
But it's unclear whether this move can cut off the possibility of invasion from the Jiuli World.
