Chu Yu was about to inquire further when Wang Yizhi shifted the topic, asking her about the distilled water she had mentioned the other day, "That thing you told me about a few days ago, everything else is fine, but there is one thing I simply cannot fathom, could it be that water, once boiled, becomes much cleaner than it was before?"
Chu Yu knew he probably wouldn't elaborate further, so she followed his line of questioning, "Brother Yizhi may not know this, but although the water we use daily appears clear and transparent, there are many specks of dust in the world that our eyes cannot see."
Wang Yizhi playfully retorted, "If they cannot be seen, how do you know they exist?"
