Zhang Xiaoman's attack left the Observer completely stunned. Not to mention the terrifying attack power of the Purple Cloud Divine Sword, just the destruction aura contained within it was enough to completely subdue the Observer.
If it were someone else, they might not have such a keen eye. But the Observer was different; he had, more or less, tested the Supreme Series himself in the past.
Even though he had not yet entered the Upper Transcendent Level, and even though he had not clearly understood the information about the Supreme Series, he still had some basic impressions and perceptions.
So now, when Zhang Xiaoman used the power of destruction, he quickly noticed it and realized that this power was extraordinary and likely quite high up even within the Supreme Series.
"This... how is this possible... Could it really be that he is...?"
At this point, the Observer began to doubt his previous judgment.
