Many tasks in the Ancient God World, especially the high-level ones, are incredibly challenging.
For instance, Li Yao's mission of the Touch of Darkness, the queen stipulates that you can only receive a clue by obtaining the first kill.
However, the problem is that there's only one first kill, and it's linked to the main line of copies, and there are definitely many missions related to the copies.
There are other lucky players apart from Li Yao, who certainly have obtained some good things, clues or tasks which require a first kill to obtain.
Take Dumb Bubbles for example, her mentor has also given her a task to utilize blank totem to absorb the essence of the Ancient Tree and acquire a new totem.
If she isn't part of Li Yao's team, her mission would inevitably fail.
Even if she could receive the same mission again, the reward from it would certainly be a tier lower than the first mission.
