When Jian Wushuang and Hu Qing desperately fled, they managed to escape quite far. Even though Jian Wushuang was flying at full speed or teleporting continuously, it still took them a day to reach the Qishen Temple.
But the Emperor was different. If he truly intended to rescue them, he could probably arrive with just one teleport.
Moreover, while they were fighting against the Sprites, he could sense a terrifying aura emanating from the direction of the Qishen Temple.
The being emitting this aura had either fallen or an unprecedented great battle had occurred.
Such a powerful clash between beings could be sensed from such a distance. If they got closer, they might be crushed by the fluctuations of the aura.
Jian Wushuang didn't know that this was happening under the suppression of Chishui and Demon Lord Fengyu. If Daogong did not suppress it, the aura waves spreading out could have injured their divine bodies.
