What Huang Quan couldn't do, he had done it himself.
Was it because he was a genius?
No!
This was definitely due to the Time Ancestor Shadow Staff that Kong Yuhen had given him. It was too powerful!
This was the first step for Number Two to confirm his identity.
As for the second...
Xu Xiaoshou thought that the fact that his confused memory of Kong Yuhen's face might have contributed to the success of his disguise.
Even the Holy Emperor's Lv.0 Perception did not have a clear memory of Kong Yuhen's face. It was very likely that Number Two was the same.
After all, he was only a Demi-Saint, not a Holy Emperor!
Dao Qiongcang who created him was only as famous as Kong Yuhen, not far better!
"Kong Yuhen's records were unknown. He once appeared briefly among the Ten High Nobles. There were no further records of his appearances after that."
