The improvement of his comprehension in the way of the sword was one aspect.
Lu Yuan felt that the greatest improvement this time was actually in his Shapeshifting.
As mentioned before, the essence of a Dharma Idol was the feedback from the cultivator's heart.
There were only two ways for cultivators to improve their Dharma Idols.
One was to improve one's state of mind, and the other was to improve one's understanding of the law.
The former increased the power of the Dharma Idol while improving oneself. The latter increased the power of the Dharma Idol through the method of laws.
The enhancement of the Disha sword intent to the Lesser Celestial Eradication Sword Array was the latter.
Lu Yuan used his inner vision to look into his body.
The blurry Dharma Idol seemed to have become much clearer. The immortal swords surrounding the Dharma Idol had also undergone a considerable change.
