"What do you mean, grandmaster? Are these people not human?" Dahlia asked.
"You are an alchemist, young man?" the spider asked.
Ning ignored the spider and answered, "No, these are definitely humans, but their blood is not. It's…" Ning felt their blood again and said, "… it's like the blood they have doesnt' belong to them. It's like, they had someone else's blood. However, it couldn't adapt to their body, so it changed."
"Yes!" the spider shouted. "The one I ate said something similar. That human said that it was here to get me so that they can get stronger by taking me away and devouring my blood."
Ning brought out a little more ingredients and did some more experiments. After a while, he said, "I see. I think I have a general idea of what is going one. Shit! This is going to turn into a problem."
"What? What's wrong?" Dahlia asked.
