Wang Chen, a modern social animal, traveled to an ancient fictional world where Confucianism and Taoism were respected, and became an orphan from a poor family without enough to eat. He discovered that the "literary spirit" and "awe-inspiring righteousness" of this world are real and powerful forces. Scholars can pass the imperial examination and practice, and finally "follow the law" and become a saint who can determine the fate of mountains and rivers with one word. Without a systematic golden finger, Wang Chen relied on modern knowledge and ideas that were thousands of years ahead of his time to conduct a subversive interpretation of Confucian classics and embarked on an unprecedented holy path of "investigating things to gain knowledge". He pretended to be a pig and ate the tiger, crushing him all the way from the provincial examination, stirring up trouble in the court with his "heretic" attitude, and engaging in a life-and-death struggle for ideas and power with the hypocritical and conservative scholar of the day and the Taifu who was both his teacher and his enemy. In the process, he got acquainted with Feng Qingyi, the mysterious empress who was at the center of the power vortex. The two gradually became spiritual partners from political allies who tested each other. Wang Chen used modern social science, economics, science and engineering knowledge to carry out reforms, enrich the country and strengthen the military. Finally, amidst internal and external troubles and the test of heaven, he proved the Tao with his own life and achieved an unprecedented holy status. He also gradually revealed the truth about his own journey and the ultimate secret of this world.
