Chapter 20: Another Attempt (2)
Yu Hong stretched his hand to warm up for a moment, suddenly feeling an unbearable thirst. He stood up and walked to the wooden barrel to scoop some water to drink.
The water in the barrel was quite murky, a faint grayish color, but it was much better than the foul-smelling water.
Yu Hong took a piece of dry charcoal, used an axe to cut off a small piece of cloth, and wrapped the charcoal inside. He then placed it on top of the wooden cup he intended to drink from, just the right size to stay in place and not fall out.
With this, he had made the simplest, rudimentary charcoal filtration cup.
He carefully and slowly poured water from the barrel over the cloth-wrapped charcoal.
The water slowly seeped through and then very slowly dripped out from beneath the cloth, falling into the cup.
Yu Hong observed and found that the water, at first, had some black charcoal residue, but gradually became cleaner, much clearer than the water in the barrel.
Although still murky, it was an improvement.
“Water must be drunk, it can’t be lacking. Let me see if I can reinforce and improve it. If not, I’ll go to the little stammerer’s house for help.”
