900 Reunion with an Old Friend

This was a clash between modern and old thought. Lu Shu knew the consequences of the lack of hygiene. He had asked whether Li Heitan and the rest often fell sick. Li Heitan said that some people had died of an illness. He did not even know the exact cause of their death.

Lu Shu and the rest had met many strong creatures in the forest. Lu Shu had even seen a Rank Two creature. This was what he was often worried about. There was a high concentration of magical energy here, but this did not mean that the only ones who benefited were humans.

Lu Shu realized that even the leeches in the dark pools of water could cut the skin of a Rank Three Practitioner. What about parasites? They had definitely mutated as well.

He had caught a leech to experiment with. The leech only died after being submerged in water for a minute. Thus, Lu Shu required the soldiers to boil water for 2 minutes before drinking it.
