The dark-robed cultivator had just crushed a skull, which was a special spiritual artifact refined from his own essence blood.
It was also known as a Blood Tool.
Inside the Blood Tool was a sealed path of Obliterating Blood Light, possessing extremely strong offensive capabilities, capable of cutting through the Body Protection spells or magic artifacts of Purple Mansion cultivators.
Once struck by the Obliterating Blood Light, the victim would suffer from the effect of burning blood and incinerating flesh.
Using their fresh blood as fuel, they would be burned alive into ashes!
This was the dark-robed cultivator's strongest trump card. If it weren't for almost being crushed by Wang Chen's Vajra Fist, he wouldn't have used this ace up his sleeve so easily.
After all, it was a one-time spiritual artifact.
Yet the dark-robed cultivator could never have imagined that his trump card would be ineffective against Wang Chen.
