"Is it because they're more valuable?" Mirel asked thoughtfully.
The Silver Level creature materials might not interest Li Zheng, but for Gold Level or above, the difference is clearly just in value.
"No." Li Zheng shook his head unexpectedly and said seriously, "It's because of their strength."
"Strength?"
"That's right!"
Li Zheng explained, "Actually, I've roughly studied the creatures in the Matrix and found that Silver to Gold is a dividing line."
"Before the Silver Tier, including Silver creatures, their strength is quite limited, and it's rare to find beings with special abilities."
"Even if they do exist, it's impossible for them to live together on such a large scale."
At this point, Li Zheng recalled the Ice Giant tribe, which was obviously an exception.
"But Gold Level is different; at this tier, the probability of having special abilities is much higher, and their combat power difference is like night and day."
