After leaving the subdivision of Yun Province War Zone, Su Mu pondered about the future, and unknowingly, while overlooking from the mountain peak, a massive crater suddenly appeared on the ground.
A piece of shattered stone fell.
At a certain height of its fall, it was suddenly crushed by an invisible force.
Bang.
Powder flew everywhere.
Su Mu slightly snapped out of his contemplation, and memories of the Beast Cave surfaced instantly in his mind, his eyes slightly brightening as he recalled this scene.
Between each layer of the Beast Cave, there exists something called the World Membrane. When breaking through the World Membrane, the flesh needs to withstand a force pressing from inside out, which relates to the size of the Beast Cave.
The larger the scale of the Beast Cave, the greater the pressure encountered when breaking through the World Membrane. Moreover, this pressure is even greater when exiting than when entering.
