Ye Haoran traveled through time and became a Jinshi of the Great Zhou Dynasty. He was demoted to a prison for accidentally breaking into the empress's bath. In order to save himself, he wrote "The Most Straight Talk in the World" to denounce the government, shock the cabinet, and force the empress to release him. After being released from prison, he entered the Tongwen Library and proposed "punctuation marks" to solve the problems accumulated in thirty years of memorials. At the same time, he investigated the case of missing people in Pingkangfang and discovered that the Wu family was secretly raising dragons and plotting rebellion. While dealing with the empress, the regent Shangguan Wan, and the oiran Gu Panpan, he gradually exposed the Wu family's conspiracy. Finally, after Zhou Renxian passed on the dragon mace, he used the mace to slay the dragon, eradicate the martial arts party, and married three beauties to achieve the title of "loyal minister".
