In the book " I Demonstrate Transcendence with Sword Truth ", the cultivation method of swordsmen was to constantly swing the sword, feel the veins of the long sword, and swing the sword tens of thousands of times to familiarize themselves with the sword style, gradually creating a supernatural system,'Sword Truth.' The path of sword cultivation required one to walk with a sword, and it was close to the Dao. Only when the sword cultivator had the utmost emotion and nature, was invincible in the sword, had a pure and persistent state of mind, was loyal to the sword path, and had no distractions could one possibly climb to the peak of the sword path.
