Cui Tiq pulled out a sheet of paper, took a pen from his shirt pocket, and drew several gentle wavy lines on the blank paper. "This is the simplest way to draw a river. Why do we consider such lines to be water?"
Li Banfeng couldn't answer.
Cui Tiq put away the paper and smiled. "Knife Labor Ghosts have different vision from us. Just as we perceive lines as river water, other creatures cannot. When these lines are transmitted through our sight to our minds, our brains generate corresponding amines and enzymes, producing specific proteins. These proteins solidify in our cognition, causing us to perceive these lines as water. But what if I told you this is a disease? Would you believe me?"
"What disease?"
