Shen Yuan, a scholar from a poor family, embarked on the road to the imperial examination in order to protect his only relative, his sister. He unexpectedly discovered that the "benevolence, justice, etiquette, wisdom and trust" in the sages' books could be condensed into supreme power - Haoran righteousness. From then on, he used the pen as a sword and the ink as a sharp edge. He was able to stabilize the country with his literary skills and slay demons with his martial arts. In the court, he outsmarted the powerful ministers, implemented the New Deal, and became a reformer respected by all people; in the spiritual world, he fought with the Confucian scholars, followed his words, and was promoted step by step from a scholar to a Confucian and Taoist saint. In the process, he met Su Muxue, a mysterious woman who disguised herself as a man. The fate of the two was entangled, and they jointly uncovered a series of shocking conspiracies, and finally faced the ultimate test from heaven and fate, and pursued the truth hidden behind reincarnation.
