Having crossed the Primordial Sea, Song Jian followed the guidance of the robot Nafiboja and entered another passage. It was only then that Song Jian realized there were innumerable tunnel entrances on the other side of the Primordial Sea. These entrances didn't look naturally formed, but rather as if they were excavated by giant earthworms. Almost every entrance looked identical, and without the guidance of the robot Nafiboja, Song Jian might have had no choice but to use a Town Return Scroll to leave without accomplishing anything.
These passageways on the Primordial Sea side were even darker. At least in the previous tunnels, there were many precious ores emitting glow, which allowed for barely sufficient visibility to walk. Combined with the light emitted by the robot Nafiboja, Song Jian had made it to the Primordial Sea with no difficulty.
