Wang Zhong, Where's My Cola

Occasionally, a handful of plants could still be seen in the desert — for example, the cactus, aloe vera, the centennial orchid, the ammopiptanthus mongolicus, etc. Gong Yi knew how to get water from the desert sand. He would dig downwards, following the rhizomes of these plants and would often succeed in digging up wet sand. He would then wrap the wet sand with a thin cloth, squeeze for water immediately or hang them up at night, to get water the next day.

But even so, that meager amount of water was definitely insufficient for four people. In fact, Gong Yi had already drunk his own urine, but soon his body was so dehydrated that urine could no longer be produced.

This was extremely terrifying. The human body produces a lot of toxins every day, and almost all of them are excreted through urine, but now, even their kidneys were about to stop working.
