The two proud sons of Penglai flushed at these words, yet their eyes were filled with both shock and doubt.
Although Ye Xiao had only thrown a single punch just now, that punch was enough to tell them what his current strength was like.
One punch, to shatter a top-grade Flying Sword!

Ye Xiao was still younger than them by some years...

Aside from this possibility, he really couldn't think of any other explanation.
The moment this question was asked, his face became filled with incredible fear.
What kind of monster could condense an Immortal Bone at the tender age of just over twenty, like Ye Xiao?
"Is condensing an Immortal Bone really such a difficult thing to do?"
Ye Xiao asked with some surprise.
