The Secret Technique of Taoist Medicine: Guarding the Mountains

Going back in time to more than a thousand years ago, Yuan Tiangang met Xu Maogong, and he took out a few inconspicuous brass plaques. Since then, some nobles from various places have quietly taken root in the mountains and lived a life of returning to their gardens and fields. Eight hundred years ago, on Wudang Mountain, there was an old man followed by a tiger, and he left several medical books and a book of exercises in a cave on the main peak. Five hundred years ago, Liu Bowen escaped by feigning death after cutting off the dragon's veins. After that, his whereabouts were erratic, traveling in all directions, and finally disappeared without a trace. However, in Lai Buyi's hometown, he hid half of the village, leaving only one dragon's cave crystal. That dragon's cave crystal was enough to save many mountains and rivers where the vegetation had lost their vitality due to the exhaustion of spiritual energy. More than a hundred years ago, a young Taoist priest accidentally obtained several medical books in a cave, but he did not know that those books were originally left for him.
