The river water of the Flowing Sand River was rapid, and there were countless undercurrents that carried a large amount of fine but sharp sand.
This was just like the water jet cutter in his previous life.
For ordinary water flow, no matter how high the pressure was, its cutting ability was still very ordinary. However, if diamond sand was added into it, the water jet would be a true saber. It could cut through metal and jade in an abnormally terrifying manner.
It was the same for this Flowing Sand River. The high-speed water current wrapped in yellow sand could sharpen a lump of iron ingot in a short period of time.
Ordinary cultivators could not fly or float in the air before the Flowing Sand River World, much less enter the water.
Ordinary flesh and blood bodies would be completely destroyed underwater for a moment.
However, Jiang Li possessed Dragon Blood, Dragon Pearl, and Dragon Soul. With a shake of his body, he became a black dragon.
