What would happen if Xuan Feng transmigrated into the primordial world as one of the innate humans?

"What? The human race was founded less than a thousand years ago. How do they already have more Great Golden Immortals than we do?"

The Wu race:

"What? The human race has an entire legion, every member of which is as powerful as a Wu Ancestor."

The Six Saints:

"What? The human race is only ten thousand years old. How do they already have a Saint?"
