Hailing from Sacred Grounds, being greatly experienced and knowledgeable, after their initial shock and incomprehension, the group of Heavenly Thunder Hall martial practitioners had already reacted by this time.
The rare treasure Imitation Killing Jade, for a period of time after its use, would let one's flesh, blood and aura-qi imitate that of the target that had been killed.
As long as the user did not engage in combat, even their breathing patterns and inner qi on the outside would be completely the same as that of the imitated target.
Ah Hu's understanding towards that Heavenly Thunder Hall Martial Grandmaster was limited. Not being clear on his usual habits, his imitation of him could not be considered intricate.
However, amidst the previous chaotic situation, he had remained careful not to reveal any traces, successfully hoodwinking the people of the Heavenly Thunder Hall within a short period of time.
