Truth be told, Zhao Guang had also researched this type of medicine, considering he had encountered it when dealing with Bimong.
However, what Zhao Guang now wanted to research was more on things that could stimulate Qi-Blood. He'd think of a way to obtain it later. If he could produce this, it would be of great help to the Empire.
After all, Cultivation Techniques spread easily, but substances that increased Qi-Blood were not so readily available.
Especially for some special species, as long as he could make good use of these species, his country would then be able to leverage against foreigners in many areas.
Thinking of the ways foreigners had controlled his country over the years, and the sanctions they imposed on him, Zhao Guang fumed with anger.
With his character that brooked no insult, how could he possibly let them off. He might not have had the opportunity before, but they'd better just wait. With this output, his next set of plans could unfold.
