The giant waterwheel with a diameter of over two meters slowly rotated, thrilling every spectator who saw this scene.
[Damn, that's a huge waterwheel!]
[So this is what a sewer looks like? The movies didn't lie to me]
[I always thought it was fake]
[Why is it still turning, is there still electricity?]
Bi Fang pointed at the water channel below the waterwheel, "The waterwheel has already stopped; it's the flow of water that's pushing the blades. It has rained yesterday and the day before, accumulating lots of wastewater in the sewer, which naturally flows towards the ocean and rivers at lower elevations. Also, due to the unique structure of the blades, they continue to rotate, though the force is weak and it can be easily stopped."
Here, the sewer had widened to resemble a river, with droplets of water jumping and rolling between the blades, carrying large swathes of polluted algae.
