This rune combination—had to admit—was rather interesting.
His own Great Dao combination approached things from another angle, belonging to a layered structure.
The greatest difference between the two was likely their differing life forms. A layered structure was undoubtedly more suited to flesh-and-blood beings like Li Su, making one's own Great Dao more stable, while a combination structure was undoubtedly more suited to Metal Life, allowing for ceaseless transformation and calculation.

Thinking of this, Li Su could not help but sense the shadow's remains that he had severed into two pieces and tossed into the Ghost Domain of Buddha Land.
