The weaker cultivators couldn't possibly watch the battle between the existences at the peak of the heroic ranks.
Not even peak rank 5 cultivators could survive the shockwaves released in that battle, meaning that all the heroic assets of the four countries had remained in their territories while the powerhouses fought.
Those assets knew that their leader had engaged a fight against the rulers of the pack of winged beasts, they would have noticed the battle even if no one warned them.
Flashes of multicolored lights had filled the sky above the center of the continent, and earthquakes had spread till the coastline for the whole duration of that battle, it was impossible to miss them.
However, those heroic cultivators had been warned because they were aware that the remaining specimens of the pack would submit to their instincts once their leaders were defeated.
