In truth, whether he knew the Heavenly Spirit Race's information or not was no longer important to Mu Feiyang. As long as the Heavenly Spirit Race dared invade the Saint Realm, they could simply be wiped out.
So when the Heavenly Spirit Race refused to reveal any information, Mu Feiyang casually incinerated it with a stream of true fire. Keeping it around meant worrying about it escaping; killing it would settle everything once and for all.
"Dad, you just killed it like that?"
"What else? Did you want to keep it around for New Year?"
"Once Little Black and the others return, we'll make a trip through the other four domains of the Saint Realm, kill all the Heavenly Spirit Race members and blood slaves, then wait quietly for the Heavenly Spirit Race army to descend."
"Alright, then!"
Mu Qingling could only agree. Since the Heavenly Spirit Race refused to divulge its information, this was the only way now.
Meanwhile, after Little Black and the others led the Spirit Immortal Palace experts out of the Spirit Immortal Palace, they followed the information Mu Feiyang had given them and visited the blood slaves' hiding places one by one, clearing out every last blood slave.
Because all the sects and sacred lands in the North River Domain had formed lightning and fire squads to patrol, the blood slaves had no way to hunt humans to raise their strength. Every blood slave had hidden away in the mountain ranges.
The blood slaves could only rely on hunting demonic beasts to increase their strength. However, demonic beasts with high cultivation were difficult for them to kill, and they were afraid of drawing human experts' attention, so they could only secretly hunt low-level demonic beasts to improve themselves.
This caused their strength to rise slowly.
