Wu Xuancang fell silent for a moment. After hearing this, the others were hardly lighthearted either.
The pressure Kui Yong placed on them was still too great.
Huang Xiao heard this and felt somewhat helpless.
All they could do now was give it their best.
Neutralizing the Demon Refining Formula was easy for Huang Xiao, and he soon finished.
Next, he had to conceal his present state from Kui Yong and make him believe he still had the Demon Refining Formula, so that he would remain unguarded against him.
He had previously considered using the Ten Thousand Demons Skill to imitate that aura and deceive Kui Yong.
But now, Huang Xiao rejected that idea.
The aura imitated by the Ten Thousand Demons Skill might fool some other experts, but it would have practically no effect on Kui Yong.
After all, this cultivation method had been passed down by Kui Yong.
Would doing so not be like showing off his axe before a master carpenter?
Since imitating the aura with the Ten Thousand Demons Skill would not work, Huang Xiao thought of another method.
That was to use the Spirit Turtle Fetal Breath Art that Senior Xuan Tu had taught him.
When Senior Xuan Tu had taught him this cultivation method, it had been to let him conceal the aura of the Longevity Chapter.
