As Yi Xiu shouted angrily, the ten Holy Palace experts surrounding the Dark Venerable emitted an extreme Power of Righteous Law.
Almost instantly, the Dark Venerable noticed that the Blood Darkness Power within him was running slowly.
"Damn it! It's actually the Ancient Evil Slaying Formation!"
Regarding this formation, the Dark Venerable had read about it in the scriptures.
According to the records, this formation can slay Foundation Establishment Cultivators!
What made his face change dramatically was that the cultivators who deployed the Righteous Law Demon Slaying Formation were all Holy Palace Cultivators trained in the Power of Righteous Law!
If there were only one or two, it wouldn't be an issue.
They would still be unable to suppress his Blood Darkness Power.
But it was different when ten High-Strength Cultivators cast it.
The Blood Darkness Power within him showed weakness.
