During the Northern Song Dynasty, the situation in the court was treacherous. Corrupt officials and tyrants were rampant in the countryside, and powerful people inside colluded to manipulate the law. Wrong souls were everywhere, and people cried to the sky. The principles of heaven are clear, but because of the ignorance of people's hearts, they are covered in dust, and the lives of common people are trampled on like grass. In this current situation where darkness and corruption are intertwined, an honest official with a dark face and a bright moon hanging on his forehead, wearing a black robe and holding a thunder pen in his hand, embarked on the road of avenging the world. He resolves cases like a god, with a heart as solid as stone, and is not afraid of swords, mountains, or seas of fire. He only believes in the words: "The people are the foundation of the country, and the law is the balance." He is not only a cold-faced judge, ruthless when trying cases, and a few words can determine life and death; he is also a supporter of the people, speaking softly when visiting people, and listening to the cries of poor families. Regardless of whether his opponent is a powerful prime minister or a noble man who manipulates the law, he stands at the forefront of the storm with his integrity and vows to open a ray of light for the common people. The story unfolds a series of twists and turns of the public cases: there is a civet cat exchange for the prince involving the secrets of the palace, there is a case of guillotine intertwined with grievances and temple intrigues, there is a case of guillotine Guo Huai who points directly at the power of the uncle, and there is also guillotine Pangyu who pursues corruption and seeks innocence for the deceased. Every case is full of dangers, with many powerful people involved, and serious cases involving murder. If you are not careful, you will be in a desperate situation. However, he is not afraid of power, does not show favoritism, would rather break than bend, uses the law as his blade and his heart as his scale, lighting up the darkness in people's hearts. Those wronged souls were finally brought to light, and the truth that had been obscured by power was revealed. He cut off the vines of lies with his cold words, and guarded Li Shu's peace with his fiery compassion. In these legends, there are not only the complicated and confusing cases and the exquisite layout of reasoning, but also the persistence of fairness and justice despite the storm.
