The entire tomb was filled with pitch-black demonic energy, like a vast plume of smoke, oppressing everyone to the point of almost suffocating.

"Witch! What on earth is happening here? Why is my power suppressed by thirty percent?"
"And why can't I absorb the surrounding demonic energy and convert it into True Qi?"
