To ordinary cultivators, the most important things were spirit qi and spirit stones.
This was the same for demonic cultivators.
It was just that for demonic cultivators, their equivalent of spirit qi and spirit stones was blood food.
Mortals' blood, flesh, and souls were incredibly important resources to demonic cultivators.
That was why demonic cultivators were called as such.
As long as they had enough blood food and souls, they could quickly become stronger and break through bottlenecks.
This was why the Demon Sect was attacking the Yue Kingdom.
Apart from taking the Yue Kingdom's five sects' fortunes and resources, there were also the Yue Kingdom's mortals.
That was what they were the most interested in.
Even though ordinary spirit stones and spirit qi were important to them, this was the same for mortals' blood food.
