Mige jumps from one tree branch to another with agility. The other orcs behind him followed at the same speed. Nevare and the women followed behind them at the same speed, Nerphyl in his white tiger body ran through the trees without touching them at all.
The two asuras who were at the forefront saw their movements that were still unknown to the Quadruple Arachnids Colony. They never killed the Quadruple Arachnids they passed because they knew their minds were connected to the hive mind. If even one Quadruple Arachnid was killed then the Arachnid Queen would know their movements.
Therefore they avoided all the Quadruple Arachnids they came across. With the inner eye of the asuras, this is easy to do. Even though the number of Quadruple Arachnids killed by the poison gas ball explosion was in the hundreds of thousands, there were still tens of thousands of other Quadruple Arachnids who were still on their way to Bitter Maja.
