The drone successfully rose into the sky. The body itself was invisible, so not even Zhao Yu could see it. As the drone flew higher, a new control panel appeared on Zhao Yu's system, and he could clearly see the video the drone captured.
Good, good… this is awesome! Zhao Yu was controlling the drone and looking attentively for his target.
With his newly widened field of vision, Zhao Yu quickly saw on his screen an overview of the area and the many well-connected paths behind the Phoenix Building. Other than the small group of people gathered outside the palace, there was no one.
Zhao Yu estimated that based on the direction and distance the person with the gun was most likely within this group.
They were probably tourists. Amongst them was a tour guide, holding a flag standing right at the front, guiding them. Their footsteps were hurried. They were probably looking for the exit since they had received a notice to evacuate.
