According to legend, whenever Heiyuan appears in the world, there will be a catastrophic event that destroys the heavens and all worlds, and restarts the universe.
Lin Fei is a young man who is unable to practice due to a defect in his tendons, so he relies on his cleverness to survive in the Sword-seeking School. When the catastrophic event occurs, Lin Fei’s mentor and best friend dies in battle against Heiyuan, causing Lin Fei to regret not making more of his life. Determined to avenge his mentor and prevent the same tragedy from happening again,
Lin Fei sets out on a dangerous journey to learn the ancient weapon refining method and defeat the demon leader Yuanhuang. Unfortunately, Lin Fei dies in this battle, but is mysteriously reborn in a new era. In order to protect the Sword Asking School and prevent another catastrophic event, Lin Fei resolves to start anew as a marginal disciple and cultivate the way of ten thousand swords, gathering the strength of heroes to break the cycle of destruction and continue the fire of civilization.
