The Human Sword Master

The most extreme swordsmanship in the world is called "Heavenly Sword of Forgetting Love". The key is not in the moves, but in the human heart. If you want to practice this sword, you must first cut off all emotions and thoughts, use the heaven and earth as the oven, use loneliness as the firewood, and refine a flawless sword heart. Chen Yuan is the only successor of this swordsmanship that has not been seen in a century.
