The saying "A man grows cunning with age, a horse grows sly" fits perfectly to describe Qing Lao, Liu Zixuan felt.
Previously, Qing Lao himself admitted to knowing many secrets within the Profound Sword Sect that even the Sect Leader and Elders were unaware of. This suggests that he has been with the sect even longer than Sword Venerable Ling Xiao, likely being a figure from the time of the previous Sect Leader.
Therefore, no matter how deeply Liu Zixuan tries to hide, he cannot conceal anything from this old fox.
Through various inquiries about the Nether Fire Stone, if one thinks carefully, one can discern Liu Zixuan's great interest in it.
Since he's already been exposed by Qing Lao, Liu Zixuan decided it wasn't worth hiding anymore.
Firstly, one lie requires countless others to cover it up, and he simply doesn't have the time to make up so many lies.
