Zhou Ning approached, holding a folded document in his hand—actually, it was a hand-drawn relationship diagram he had made. Folded up as it was, no one else was able to see the contents. He casually shook the document at Wang Wenjing before he began to speak slowly.
"Last night at Zhang Guanglei's home, we found two bottles of self-filled traditional Chinese medicine capsules, the kind with printed labels, dated 2011.7 and 2011.8. No handwriting was left behind, very smart indeed. However, 'Diphacinone' is a fat-soluble chemical."
Moreover, 'Diphacinone' is completely insoluble in water. That means once it gets on your hands, it seeps into your skin or stays in the crevices of your nails, mixing with the oils on the surface of your skin. Only when you come into contact with fats will it partially dissolve.
