Cultivation Apprentice

In ancient times, hundreds of schools of thought contended. Although they are called hundreds of schools, there are no fewer than tens of thousands of schools. Among them, ten are the most famous, namely: Taoism, Confucianism, Mohism, Law, Military, Zongheng, Yin and Yang, Medicine, Agriculture, and Ming. The protagonist is a mortal with ordinary bones. He has determined to cultivate since he was a child, but his bones are considered to be incompatible with immortality. Fortunately, he became a disciple of a time traveler, and thus became the director of both agriculture and medicine. So, what kind of stories can he, an alternative cultivator, trigger in this post-a hundred schools of thought era?
