No one had expected the battle to last this long, and neither had they expected that more than twenty Nascent soul realm beasts would descend into the Millennium forest today. All of them were from the Tapir Tribe and were the same kind of beasts.
Lin Wu had read the information about the Southern Tusk Tapirs by now and had learned that they were highly territorial, and this also meant that they would only move from their land in very specific conditions.
One of the reasons was if a certain Tapir beast was exiled from the tribe but had a lot of subordinates. Then those members would probably follow that tapir beast and occupy land somewhere else.
But it did not seem like that was the case here, since there were over twenty Southern Tapir Beasts here. This led Lin Wu to believe that it may be due to some other reason, and that was the expansion of a tribe.
