章 270: Clues

Qian Fei Liu smiled. "If you want to know more details, you need to ask other doctors. What I know is very limited."

"Is there anything that you want to know?"

Feng Yu Hua tilted her head and then asked, "Do you know anything about DNA test?"

"DNA test has never changed from the past to present. What changed is just the method to analyze it so that it could be faster." Qian Fei Liu arched his eyebrows. "Why are you asking about it? Do you want me to explain what is DNA? But I'm sure that you have been taught when you're still in junior high school back then."

"No need, I'm just curious about other identification method aside from DNA." Feng Yu Hua smiled faintly.
