"Why drink urine?"
When he couldn't figure it out, he simply asked.
Song Yin said in a deep voice, "Has something happened here? Has it led to you having no water to drink?"
This was not merely a liquid that resembled urine; he was of the Hunyuan Dao, skilled in alchemy, and even without the use of the Dharma Eye, he could discern what this substance truly was through his Dharma Technique.
This urine also had a certain medicinal value; by using only the middle portion and discarding the beginning and the end, then processing and refining it, it could be made into 'Samsara Wine' and 'Rejuvenation Soup', which could treat symptoms like bone-steaming fever, consumption and alternating fever in the lungs, vomiting blood and nosebleeds, bleeding gums, postpartum dizziness due to excessive blood loss, and so on.
