The surge is not instantaneous but the traffic of monsters trying to get to me is getting bigger and bigger. I managed to kill most of the monsters that are trying to block me since they are low-level monsters but that doesn't mean I will not encounter stronger monsters. I also felt the ground shaking, meaning some of the bigger bosses around are also just around the corner, ready to attack.
I didn't focus on the monsters and focused on the second secret base's location. The surroundings are surrounded by large unknown structures, making a maze-like path for me to take. Smaller monsters can follow through but monsters who are big can only stay above as they won't fit on the pathways. Thankfully, the unknown structures are strong enough that even if the monsters try to break and bash them, they still remain intact.
