In the prosperous age of the Han Dynasty, the world was peaceful and undercurrents were surging: the entanglement of interests in the Yantie government camp, the knot of the vassal king after the favor was extended, the mysterious phantom of alchemy and witchcraft, and the swords and swords on the Silk Road in the Western Regions, all intertwined into strange cases and conspiracies that spread throughout the world. Wei Zhao, the former magistrate of Du County, was reprimanded for his uprightness, but he was appreciated by Emperor Wu and was awarded the deputy position with embroidered clothes. He led Zhao Yi, a loyal and brave captain who was born in the Yulin Guards, Su Heng, a descendant of the Mohist family who was knowledgeable in medicine and government agencies, and Jing Liu, a bad guy from Chang'an who was familiar with the market, to patrol the world in compliance with the imperial edict. They broke the blood curse in the countryside, investigated the phantom in the palace, hunted down the bandits on the Silk Road, and resolved the suspicions of the vassal king. They wandered between the governing principles of Confucianism and law and the bizarre folk magic, and they insisted on justice in the whirlpool of intrigues and the test of life and death. Every strange case has its twists and turns, and every duel shows wisdom and tactics. From the city of Chang'an to the deserts of the Western Regions, from the fertile soil of Sanfu to the dangerous lands of Bashu, using embroidered clothes as a basis and the truth as a blade, in the magnificent era when Emperor Wu of the Han Dynasty opened up territories and reformed the system, he wrote a series of legends of "breaking mysterious cases with iron face and protecting the prosperous age with loyalty".
