Chen Feng's reply was simple.
"The human heart," that was his research subject.
But Wang Qi was not satisfied with this conclusion, "Who are you trying to fool? Is this huge project something you can research all by yourself? It's not like the discipline was just established. Be more specific."
As research deepened, disciplines would branch out into finer and finer specializations. Taking Earth's history as an example, during Galileo's era, a fairly strong scientist could research all the physics that was available to be studied. However, by the beginning of the twentieth century, even Einstein couldn't cover the entire domain of physics.
When Chen Feng said "the human heart," it seemed too vague. According to Wang Qi's previous life's research methods, just one functional area of the human brain could sustain tens of thousands of researchers.
"Specifically speaking, it's even about the formation of the human heart," Chen Feng inquired, "Do you know of the Three Pure Ones?"
