"I'm terribly sorry. I really didn't expect the Evil Aura accumulated over so many years to be this heavy."
As the alarm slowly died down, Gu Xi spoke to the Black Robe Man somewhat apologetically.
He truly had not expected to cause such a commotion.
The Bone-Eating Swamp and Bone-Eating Mud placed in the Sewer had cleared away the sludge that had accumulated over the years after cleaning up the blood pool beneath the Sewer.
In the process, they had accidentally unearthed something left behind several hundred years ago.
It was a heart of unknown origin from centuries ago.
After soaking in blood for so many years, it had turned completely black and was nearly crystallized.
When it was dug out of the sludge, the total amount of Evil Aura exceeded what the Black Market could control, so the Black Market's Evil Aura alarm immediately went off.
This startled the entire Black Market.
After all, this alarm would only sound automatically when the Black Market encountered something valuable carrying an extremely powerful Evil Aura.
This frightened Gu Xi badly. It was only after the Black Market guards arrived and figured out what was happening that they shut off the alarm and withdrew.
As for the heart carrying such a heavy Evil Aura, Gu Xi naturally put it away.
Although he had yet to determine where the heart had come from, the powerful Evil Aura on it alone was enough for Gu Xi to keep it.
By now, the Black Robe Man had also learned what Gu Xi was capable of.
His level might not have matched the Necromancers in Qianfang City, but Gu Xi was meticulous in his work.
He even cleared away remnants that had been left behind for centuries.
He was far more useful than ordinary Necromancers.
