Word always gets out.
The Black Crow's abnormal activity on Guru Mountain was like a stone dropped into a placid lake; at first, it made only an ordinary sound, but then it unknowingly sent out layer upon layer of ripples.
Unfortunately, Guru Mountain was remote, so most could only watch the Black Crow's actions with envy, unable to keep pace. By the time they made their way there after various delays, the Black Crow would likely have already retreated. At that point, they could only eat dust, not even getting a taste of the soup the Black Crow left behind.
After all, entrenched beneath this Guru Mountain were quite a few characters dreaming of striking it rich.
