Xu Xiang put down the pestle and took out a laser dagger from her space. Crouching down, she used the laser dagger to open a small hole the size of a bamboo pole on the bottom of the wooden barrel. After polishing the edge of the hole smoothly, she took out a bamboo inter note. Then she inserted the bamboo inter note into the hole, and a simple water tube was made.
Satisfied with the result, Xu Xiang took out a bunch of cotton and stuffed it into the bamboo inter note. She then sealed the water flow tube on both sides with activated carbon fiber. Standing up, she saw A Lu Da came back with a bucket full of fine sand.
She looked at him, pointed to the wooden barrel and said, "Pour the sand into the barrel."
A Lu Da nodded and poured the fine sand into the big wooden barrel without saying a word. She looked inside the wooden barrel and saw that the first layer needed more sand.
She glanced at him and said, "We need at least six more buckets of sand."
