"The true Golden Silkworm Gu is impervious to blades and bullets, resistant to fire and water—that is the ultimate weapon." Patriarch Ou's eyes glimmered as he said gravely, "But this hybrid offspring doesn't possess the same power. I heard these hybrids can evolve over time, but no one has found a way to trigger their evolution. Now I see it—it's through cultivating them with human blood!"
The man scratched his head. "But Master, we've used human blood in the past. Why didn't any of them mutate like this before?"
Patriarch Ou shook his head. "Yes, we've used human blood before, but perhaps the quantity wasn't sufficient. These hybrid Golden Silkworm Gu must consume a certain amount of human blood to undergo such mutations."
"A certain amount of human blood... How much are we talking about?" the man asked curiously.
Patriarch Ou paused for a moment before answering gravely, "Each Golden Silkworm Gu needs at least one human to cultivate it!"
