My translation: Mr. Zhu learned the art of dragon slaying from Mr. Zhi. Spent a fortune. Graduated after three years. Find no dragon to test his art.
Comment: It rings a bell for practitioners of traditional arts. The most deadly martial art applicable in no context, alchemists searching the occult, as smart as Newton couldn't resist the lure of divine power, as if nothing short of the highest imaginable is not worth one's effort to pursue. Japanese are more modest, they have traditional martial arts for sports training, for elderly care, and needless to say for the humblest objective of health.
