Seeing that those forces really didn't dare to rashly attack Ainsley because of her main force's strength and Jake's presence, plus the two sacred beasts, the world union was in a hurry.
They knew that public opinion would only prevent Ainsley from recharging the energy needed to use her charm ability and the terrifying love virus, but other than that, public opinion wouldn't make Ainsley obediently surrender.
The World union felt that Ainsley should be the representative of all transmigrators, so it was important to capture this kid and kill her in public, so as to deter the other transmigrators along with future transmigrators.
It was just that, if they wanted to catch Ainsley now, relying on those forces alone wasn't enough, and they could only go all-out.
