After a long time, Ling Feng pulled out all the silver needles, and on the tips of the needles, they all showed a pitch-black color.
Clearly, inside these Blood Spirit Corpses, their bodies were filled with a special kind of extreme poison, these poisons could not be expelled, and they would continue to transform until they completely became monsters that were neither human nor demon.
"How is it?"
Seeing Ling Feng retract the needles, Jin Weide and Sun Gongming, among others, all gathered around and asked.
"It's difficult!"
Ling Feng's brows were deeply furrowed as he said in a heavy voice, "I have roughly gained some understanding, but unfortunately, the extreme poison in their bodies is far too strange. As far as I know, they have had part of their soul origin absorbed by some Evil Treasure. This poison can be said to penetrate deep into the soul, thus making its removal very complicated."
