Little White Dragon departed from Eagle Sorrow Stream, where the vegetation was flourishing. With the dragon's departure, the creatures of the area no longer lived in trepidation, and the once serene place was reinvigorated with life.
As a dragon, Little White Dragon had a voracious appetite. When in the ocean, food was aplenty, but since arriving at Eagle Sorrow Stream, he had been constantly worried about food, to the point where many large animals were eaten clean from the vicinity.
The remaining animals, in their fear, fled the area, which is why Tang Monk's white horse ended up being eaten, as Little White Dragon had been hungry for some days by then.
During this time, the animals around sharply noticed that the once-dreaded apex predator had inconspicuously left Eagle Sorrow Stream.
Thus, many animals returned, bringing back the hustle and bustle of former days to the land, competing once more and reestablishing balance.
