To launch an attack on the Blood Pit Fortress, one needs to pass through a side corridor of the main battlefield.
Thus, the number of enemies that the Blood Pit Fortress faces each time is limited because this is merely a sectioned-off battlefield.
This mountain range protects the Blood Pit Fortress well, allowing them to face the enemy by only needing to guard the sky and this front passage.
But correspondingly, to connect with the Blood War Fortress, you must also take this passage.
Now the defense line has moved forward.
A third of the main battlefield has been directly severed.
The third that was once close has been intercepted by the defense line, and this proximity is precisely next to the passage leading to the Blood War Fortress.
