Upon hearing the familiar rustling sound again, Leo Ray was startled and immediately commanded his subordinates to quietly position themselves along the right wall of the tunnel, listening attentively.
By carefully comparing the previous and current sounds, Leo Ray discovered.
Based on both the frequency of footfall and the messy multiple footsteps, he could confirm that these footsteps were identical to the ones that had just moved away.
This point was also confirmed by the gazes from Serena and Stella.
As assassins, Serena and Stella had undergone extremely rigorous training in hearing, making it virtually impossible for them to make a mistake.
Moreover, from the looks of Taylor and the others, Leo Ray learned.
There was also no success in detecting energy fluctuations, breath, or smell from the second set of footsteps.
Thus, an incredible answer emerged.
These two sets of footsteps, one after the other, were indeed from the same group of people.
