There were two sources of toxins in the human body. One was from metabolism. The other was from outside. External sources were more complicated. Most toxins were from food and drink. Some toxins could come from open wounds and skin contacts.

"From the well in the village," the man said.
"Where is the well?" asked Wang Yao.
"Oh, just over there, I can take you there," the middle-aged man replied as he pointed at the front.
