To enter the Soa crystal mine, one had to make use of one of the two entrances.
The main entrance was enormous and allowed even the largest beasts to easily pass through it while leaving enough space for other beasts to enter it simultaneously.
Meanwhile, the other entrance was small and barely allowed three humans to enter at once.
As such, they had decided to pierce through the defensive line of the wandering beasts by using both entrances simultaneously.
While only a small margin of the entire attacking force was supposed to use the smaller entrance, the rest used the bigger entrance.
Through this, they were able to sandwich their opponents, allowing them to focus on taking out the most threatening wandering souls first.
This was the most important aspect of their battle strategy because the strongest wandering souls could eliminate the Yinar race's entire Elite with just a single attack.
