The Holy Spirit Sword Art was the most advanced sword technique from the Sword Universe.
Its final form, the Sword Twenty-three, was the most powerful. That technique possessed devastating and even cataclysmic strength. Very few Hongmeng-level cultivation techniques could ever compare to it.
Although the version Jue Jian unleashed was incomplete, Chu Kuangren could benefit a lot if he fully comprehended it.
Besides that, Chu Kuangren could sense that the Sword Twenty-three technique was quite similar to his Heaven Slaying Sword Drawing Technique. Both were the ultimate offensive sword techniques.
After all, one could use another person's strength to overcome their weakness.
Perhaps by examining the Sword Twenty-three and cross-referencing it with the Heaven Slaying Sword Drawing Technique, he could create an even stronger sword technique.
