As Ye Chen used the Hundred-Change Mask, he changed his physique and appearance.
Thus, even his relatives and friends couldn't recognize him, let alone Dugu Ao.
Moreover, in Dugu Ao's impression, Ye Chen had just stepped into the Nascent Soul Realm not long ago, and his physical body wasn't so heaven-defying.
So, naturally, he couldn't associate Ye Chen with the mysterious person before him.
"Just wonder whether he can pass the third layer of the trial; even I don't know how difficult the third layer is! Maybe it requires mastery of a seventh-grade law to pass.
If that's truly the case, he will definitely fail." Dugu Ao thought silently to himself.
Though he acknowledged that Ye Chen's Sword Dao proficiency was really high.
He didn't believe Ye Chen could master a seventh-grade law.
After all, seventh-grade laws are incredibly hard to comprehend.
