Compared to the evil soul masters who fed on flesh and blood, those evil soul masters who swallowed vengeful spirits and wronged souls possessed a unique aura on them that could be easily sensed by Huo Yuhao.
And the evil soul masters of the Holy Spirit Cult almost all had this kind of aura on them.
Tracing that aura all the way deep into the Black Market, the space here suddenly opened up, forming another extremely spacious open area underground.
This was a circular venue with a diameter of at least fifty meters, and quite a few traces of battle still remained within the arena.
In the middle of the open space were two soul engineers who had already finished fighting, one standing without a single injury, and the other sprawled out and covered in blood.
The clearing was sunken downwards, and the upper perimeter surrounding the open space was packed with watching personnel, some with excited smiles on their faces, and others with expressions of regret.
"Haha, I bet on the right person! How could that guy possibly be a match for the Xishui Alliance?"
"He's pissing me off! I thought a Level 6 Soul Engineer like him would be quite something, but he turned out to be trash!"
Hysterical laughter and cursing rose and fell in succession.
This was strikingly a Soul Fighting Arena, and what was being held inside it was an underground soul fighting match in the Black Market.
The surrounding spectators were not just here to watch private fights and violent performances; they had gathered here with another shared purpose-gambling.
Huo Yuhao glanced at the betting bookmaker's post not far away, which only displayed a few figures: one to one point two five and one to one point two eight.
The odds were not far
