Pausing, Elder Dan Gu let out a deep breath. "The Azure Immortals seem to know the fate of every insect. They're impossible to understand, as if a pair of eyes had watched us from beginning to end, seeing every move we made. Then a creature came into being that could counter each of our moves. That creature is the Azure Immortals."
"They understand everything and can use the abilities of every insect. What's even more frightening is..."
He gazed deeply at Lu Yin, profound dread in the depths of his eyes. "Their ability to learn."
Lu Yin was astonished. "Learn?"
Elder Dan Gu spoke gravely. "The Azure Immortals have the strongest learning ability I've ever seen. In our universe, they mastered everything known to Human Civilization, without missing a thing. No matter how difficult a Battle Skill Cultivation Method was, or what path a powerful cultivator had taken, there was always an Azure Immortal who could learn it. Nothing was beyond them. Their ability to learn was simply too strong."
"The most frightening thing is that you can't tell them apart before they reveal themselves. If an Azure Immortal is an insect, then it's an insect. Unless it shows its strength, no one would suspect that an inconspicuous bug was an Azure Immortal. If it's human, then it's the most outstanding genius in human history, a Talented Cultivator whose gifts are impossible to surpass."
"To be honest, Lord Lu, I once suspected you were an Azure Immortal."
Lu Yin stared at Elder Dan Gu in shock. "You must be joking, Senior. Could these Azure Immortals really be that powerful?"
Elder Dan Gu sighed deeply. "Our universe gave rise to peerless heroes, and legendary elders crossed through time to join the final battle. In that battle, we killed every Azure Immortal.
