Zhang Heng spent some time searching the bottom of the pool once more to confirm that Jermaine Gardner was indeed not here. Just like the pit above, there was no other entrance or exit to the pool.
Thus, Zhang Heng shifted his gaze to the head of the stone carving snake. This time, Zhang Heng was no longer attracted by the pair of ruby eyes. He no longer paid attention to the lifelike carving techniques, focussing his gaze instead on the mouth of the snake.
Zhang Heng's heart skipped a beat. He suddenly understood what this stone carving was used for.
It was not an underwater sculpture of a work of art but a door!
The entrance to this door was in the snake's mouth, which was wide open.
