The Falling Sword Style's attacks were relatively plain and unadorned. Supplemented by the Nine Sects' number-one Falling Sword Step, it generated overwhelming speed to seize control of the airspace, then obliterated the enemy in the posture of a falling meteor. It was an extraordinarily powerful sword art capable of killing in a single strike.
The Divine Illusion Sword was different. Divine Illusion referred to a meridian-burning finger technique cultivated for the purpose of destroying one's dao lineage. It was essentially a cultivation method similar to great-dao arts such as the Origin Return Method and the Dao Transformation Method. Anyone struck by it would have their meridians burn with searing heat. That was also why Xun Gao had been extinguished earlier.
The Divine Illusion Sword inherited the power of the Divine Illusion Finger and released that energy through sword techniques. It likewise possessed powerful concealment. Even experts could hide their attacks, preventing others from seeing the flames of dao-lineage combustion blotting out the sky. That was why it was called "Divine Illusion."

After all, the speed of the Falling Sword Step and the one-strike kill of the Falling Sword Style possessed tremendous impact, allowing one to seize the initiative in the first exchange. It gave one a powerful advantage against an enemy, but its weakness was just as great. Once it encountered one of the Nine Sects' techniques and failed to defeat the enemy in one move, the result would be equally tragic—just like what had
