Finally, I successfully received this quest!

The personal and regional first-kill rewards for the Boss are calculated based on the grand zone.

Grand Zone 8 has over a thousand Safe Zones, and there must be quite a few areas where this quest can be triggered, not just Zhang Yi's. So next, it depends on which team's completion rate is higher.

At this time, Guan Hao, Liu Xing, and a few others who also received the [Hunt Skeletons] quest were quite intrigued.
