"I really didn't expect the malevolent energy accumulated over the years to be so overwhelming."
As the alarm gradually subsided, Gu Xi spoke somewhat apologetically to the black-robed man.
He truly hadn't anticipated causing such an incident.
The Bone-Devouring Swamp and Bone-devouring Mud placed in the sewer, after clearing out the blood pool beneath, ended up also clearing away the accumulated mud from over the years.
With a slight mishap, it unearthed some things from centuries ago.
It was a heart from hundreds of years ago, source unknown.
Soaked in blood for so many years, it had turned entirely black and was almost crystallized.
When it was dug out from the mud, the total amount of malevolent energy exceeded the level the black market could control, triggering the black market's malevolent energy alarm.
This immediately caused a stir in the entire black market.
After all, such an alarm only goes off in the presence of very potent malevolent energy in the black market.
