During the turbulent times of Dajing, the imperial power fell away, the demonic sect rose in northern Xinjiang, colluded with foreign races, and controlled corpse soldiers. The martial arts in the Central Plains fell apart and the people were displaced. Lin Yan, an outer disciple of the Black Tiger Sect, has the heart to "protect the common people with force" and refuses his master's order of "killing indiscriminately in exchange for promotion". He uses a bamboo sword to protect his wronged junior brother, and accidentally creates the "Three Ways of Guiren Sword" - martial arts to maintain integrity, swordsmanship to stop fighting, and benevolence to save people.
From individual bravery to the unity of the world, from protecting friends with a sword to the well-being of all people, this is a legend about the persistence of morality and the inheritance of strength. In the end, the "Three Paths of Benevolence" ended the troubled times and created the eternal true meaning of Chang'an in the world.
