Xue Yunrou's face slightly changed, and she immediately flew up and swept away towards the exterior of the Under Palace.
In fact, her Red Cloud Phoenix and Li Xuan's Divine Blood Thunder Phoenix were circling outside the Under Palace at this time, observing the surrounding land for eighty miles.
The Red Cloud Phoenix has recently not been progressing as fast as the Divine Blood Thunder Phoenix, but it has just acquired a new 'Vision of Xuanling' bloodline Divine Skill.
This Divine Skill could detect all traces of spiritual power within eighty miles around.
According to the Divine Consciousness feedback from the Red Cloud Phoenix, the Black Deer Demon King escaped from its observation range three hundred moments ago.
However, the Black Deer Demon King was good at hiding, so it's possible that the Red Cloud Phoenix was deceived.
