Qin Shaofeng was discovered. Although he had hidden his aura perfectly,
he had still been exposed.
Logically speaking, given Qin Shaofeng's circumstances, even some detection devices should have been unable to sense his aura.
That was because even detection devices operated by detecting a martial artist's power of qi and blood.
Yet Qin Shaofeng had concealed all of his own power of qi and blood, so naturally he could not be detected.
The reason Qin Shaofeng had been exposed to those Thunder Sect disciples was entirely due to the Identity Token on his person.
In any Upper-tier force, every disciple possessed an Identity Token.
An Identity Token was fully fused with its owner's power of qi and blood, allowing their sect to determine whether someone was one of their own and completely preventing outsiders from suddenly infiltrating their ranks.
Furthermore, every force's Identity Tokens possessed special formations.
Once such a formation was pried into or analyzed, it would collapse on its own, taking the Identity Token with it as it self-destructed.
Therefore, stealing another force's Identity Token and disguising oneself to impersonate someone else was fundamentally difficult to accomplish.
Based on this, some forces had also refined special items for detecting Identity Tokens.
This could be considered one flaw of Identity Tokens.
A person's power of qi and blood could be concealed, but the formation on an Identity Token could not be hidden.
The detection device in the hands of those Thunder Sect disciples had detected the Identity Token on Qin Shaofeng, not Qin Shaofeng's own power of qi and blood.
To be honest, Qin Shaofeng's ability to conceal his power of qi and blood so thoroughly that they had sensed nothing even from such a short distance away
had greatly shocked those Thunder Sect disciples.
At that time, they
