Swallowing the Sky Without Dirt

On the eve of the collapse of heaven, a "clean" person was pulled from another universe. This world has been eroded by alien gods for too long. Practitioners all have to pay a price - the weapon refiner becomes a weapon slave, the sword cultivator cuts off the memory, the alchemist uses people as medicine, and the soul eater becomes one with all souls. Mortals are like grass, harvested in pieces by the sect. Wuhusheng is the only one who does not need to pay the price. He devoured pollution without leaving a trace on his hands. Cost? Everyone thought he didn't. Until one day, he found that he could no longer make footprints. The body is getting lighter. When I look in the mirror, my face is blank. ——It turns out that "no price" itself is the biggest price. He is the last escape route left by Heaven. The retreat means: throw it away after use and no one will remember it.
