Sitting cross-legged on the mat inside the hall, Chen Hai, who was not deeply engrossed in Path Enlightenment, furrowed his brow and slowly opened his slightly closed eyes.
The entire Black Water Immortal Mountain seemed like just a mountain, but because it was originally an Ancient Cave Mansion, the space inside was compressed, making it vast and forming a small world of its own.
The region at the peak of the Immortal Mountain where the Cultivation Hall was located was originally the most important part of the whole area.
Given the current strength of the Black Water Lineage, for outsiders to infiltrate Black Water Immortal Mountain and reach the hall where Chen Hai was in retreat without being detected, conservatively speaking, would require at least the power of a Quasi-Saint.
However, experts at this level are among the top figures.
Throughout the vast Primordial world, someone with Quasi-Saint power is extremely rare.
