"Miss Wang, there are some things in this world that cannot be explained by science. Before we get to that, I need to educate you on something. Jade is divided into two types, one is living jade and the other is dead jade. The living jade is what we commonly see and wearing it can be beneficial to the human body, while dead jade is rare. If living jade represents positive energy, then dead jade embodies negative energy. Unfortunately, the Jade Ruyi you purchased is a piece of dead jade."
Ye Wudao began by explaining to her what living jade was and what dead jade was, knowledge that is not printed in textbooks, so ordinary people do not understand dead jade because it belongs to the knowledge of an ancient and mysterious world.
