A modern doctor who is proficient in the civil, commercial and criminal procedural law system traveled to the world of Water Margin. He rejects all "willful grudges" in the world and only believes in "procedural justice" and "sunshine judgment." He used modern legal thinking to interpret the laws of the Northern Song Dynasty, and single-handedly started a "court revolution" in an era of official corruption and gangs. He found legal provisions for Wu Song to prove the legitimate defense of "attempted murder of his sister-in-law", wrote a complaint for Lin Chong to accuse Gao Qiu of abusing his power, and even accused Liang Taishu of embezzling state-owned assets for Chao Gai. He made the heroes of Liangshan discover that violence is not the only way, and winning the lawsuit is the real hero.
