The waterways inside were incredibly intricate, akin to a maze; a random turn at any junction could lead you in an entirely new direction, with dozens of junctions to choose from. Ding Fan felt that even if Gui Luo was highly skilled, it would be impossible for him to follow them into this maze.
By now, Ding Fan had already reached the Golden Core Stage of cultivation; although he had not reached the Realm of Fetal Breathing, breathing freely under water was hardly an issue for him. As for Zhang Shanlian, Ding Fan had already used his Divine Sense to check, and the latter was also able to breathe freely underwater.
Therefore, Ding Fan was not in a hurry. He kept shuttling through the waterways without stopping.
Boom... Rumble... At this moment, a series of booming sounds came from outside the waterways.
Even without looking back, Ding Fan understood what those booming sounds were - it was Gui Luo hammering at the entrances of these waterways.
