The protagonist Wang Lin, a doctor of modern sociology and history, accidentally traveled through time and became Wang Mang's fourth son. He found himself in an extremely contradictory position: many of his father Wang Mang's reform ideas, such as land state ownership, planned economy, and the abolition of slavery, actually shone with the brilliance of "socialism" that transcended the times, which shocked and warmed him as a modern man. However, he also clearly knew that these reforms that were too idealistic and divorced from reality were the root cause of the rapid collapse of the new dynasty in history. What he faced was not a simple usurper or tyrant, but a "Father of Time Travelers" who was full of idealism but willful. The core conflict of the novel changes from the traditional "justice vs. Evil" to the profound struggle of "ideal vs. Reality" and "saving loved ones vs. Conforming to history."
