The Wang family is usually the least valued by the village chief, and they are never allowed to do anything important.

Feeling uneasy, the men of the Wang family patted their chests and said they would definitely do a good job when Lin Jinyue assigned them tasks.

Lin Jinyue showed them the approximate dimensions and then went to find Li the blacksmith.

Li the blacksmith was arguing with his wife.

Li the blacksmith wanted to throw away the charcoal, saying it was too much trouble to carry around, but his wife, Liu, said that it was good charcoal and they couldn't bear to throw it away.

Lin Jinyue then leaned closer, smiling sweetly, "Uncle Li, could you give me two pieces of charcoal? I need them very much."

Hearing that it was very useful, Liu said, "How much do you want? This whole bag is yours."

Lin Jinyue smiled, her eyes crinkling: "Thank you, Auntie."

Li the blacksmith was curious about what Lin Jinyue wanted all this charcoal for. Why would she need charcoal on such a hot day?

At this moment, Lin Jinyue was surrounded by many people, and she explained to them, "This stone must be washed clean, and the charcoal powder must not be skimped on; grind it as finely as possible."

As she spoke, she took another jar with a broken bottom, placed two layers of clean cotton cloth underneath, added clean sand and gravel, and then placed another layer of cotton cloth inside.

Everyone was dumbfounded. What was Lin Jinyue trying to do?

Lin Jinyue layered cotton cloth, sand, and gravel, and then added charcoal until the jar was full.

"Er Ya, what are you trying to do?"

Lin Jinyue: "Filtered water, Dad, go and fetch a bucket of water."

Lin Youcai quickly said, "Oh dear, how can you drink this? It's full of filth. Look how you've ruined this charcoal. We can take it to Lingnan; it'll be useful in winter."

Lin Jinyue then said, "Lingnan is warm in winter, so we don't need it. I can filter water. The water we have now is completely undrinkable, but we can't go all the way there thirsty. Without filtering the water, we don't know if we'll even make it to Lingnan alive."

"Will this really work?"
