In a world where martial arts reign supreme, a delicate balance has long held between the martial world and the imperial court, despite their deep-rooted opposition. But a young man named Jiang Gujue shatters this fragile order with a sword stroke born of unparalleled swordsmanship. He rises rapidly to become the Lord of the Heavenly Mandate, ruling the entire martial world. Cold and ruthless, he crushes all who resist with overwhelming force and proclaims, “The sword is supreme; strength is king.” From then on, the martial world is thrown into turmoil. The court's covertly controlled Martial Guards and the great factions of the jianghu continue to challenge him, while an even deeper conspiracy quietly takes shape.
