That water was no ordinary water. It was bone-piercingly cold, its temperature at least around minus one hundred degrees Celsius, yet bizarrely, it had not frozen and still retained its fluidity. At the same time, the water had a tremendous corrosive effect on protective Battle Qi, forcing Zhang Tie to replenish the expenditure of his protective Battle Qi even as he swam beneath the surface.
The pipes within the pools formed a labyrinth, immensely complex, connecting pools of all sizes and shapes one after another. Every few minutes of swimming, Zhang Tie would come across another one. At the bottoms of those pools lay strange black sand like crystal, as though it had been used to cultivate something. In several of the pools, Zhang Tie also discovered withered, broken roots amid the black sand, thick enough that two people would need to link arms to encircle them. They had soaked in the water for who knew how many years; at the lightest touch, they turned into powder drifting through the water.
The water was incredibly dense, several times denser than mercury, and the pressure at the bottom was immense. It was impossible to move quickly while swimming through it; every step forward and every stroke consumed tremendous physical strength. Had it been an ordinary Warrior, they would not merely have been crushed apart by the enormous water pressure—even trying to move would have been impossible.
Swimming through those maze-like water pipes, turning left and right behind Tang Mei, Zhang Tie had no idea where he would have ended up without her.
The two of them swam underwater for nearly eight or nine hours before entering the bottom of an even larger pool through that maze-like network of pipes.
Or rather, this was no longer a pool, but more like a
