Chapter 24: Exchange (4)
“If you still have something as good as a water filter cup, he will definitely buy it,” Jenny said with a laugh.
Filtering water had always been a big problem for her. The water filter jugs sent from the bunker were only good for filtering coarse particles. They needed to be replaced frequently.
She had just quickly checked the water filter cup in her hand. The filter inside had five layers, so it should work well.
“Would you mind if I try it?” She took a leather water pouch from her waist bag and compared it.
“Of course,” Yu Hong stepped back a little, letting her pour water into the filter cup.
Soon, clear water flowed out, and the quality was so good that Jenny’s eyes lit up. Clean water was in high demand, especially for washing wounds.
After the transaction, they each stepped back and quickly parted ways.
On his way back, Yu Hong found the soil that Jenny had mentioned. He dug up a bit and brought it back to the cave.
He planned to try enhancing it. If the soil indeed had a diarrhea-stopping effect, the Black Mark should be able to enhance it into a medicine with fewer side effects.
