Despite —
Blood Servants were basically ordinary civilians converted by the Blood Clan, so Sivis couldn't use the evil technique "Soul Sacrifice" in front of Vikalina.
Every time he killed a Blood Servant, he could only get a few soul points.
Luckily, these guys had very weak soul strength, so sacrificing them didn't yield much extra profit.
Sivis didn't care about this "waste."
But sometimes, a hint of surprise would flash in his eyes, for example —
["You have killed a Blood Servant Elite (Bronze-Rank Tenth ), and you have received four hundred soul points."]
["You have killed..."]
The elite blood servants who were specially marked were still originally ordinary people, with not very strong souls, but they had been trained by the Blood Clan for a long time. Each one could give out a decent amount of points!
So, Sivis spent a little time killing monsters in the sewers.
