Chapter 1503

For ordinary people, this was simply a great treasure trove.

With a light beckoning gesture, the Immortal-Slaying Sword returned.

Having opened a world, the Immortal-Slaying Sword had not dimmed—if anything, its radiance had grown stronger and its edge sharper.

Such was the wonder of a Great-Dao companion spirit treasure.

Progress in the cultivator's Laws could feed back directly into the spirit treasure.

The spirit treasure's progress could likewise feed back into the cultivator.

One could say that, with a Great-Dao companion spirit treasure, a cultivator's speed was twice that of ordinary Chaos Divine Demons, or even more.

Putting away the Immortal-Slaying Sword, Zhang Taixuan formed another hand seal, placing the Sword World beneath the Taixuan Realm as a subordinate world.

With the Sword World joined to it, the Sword-Dao Laws within the Taixuan Realm also grew swiftly, and the world's grade rose gradually.

Though it had not elevated the Taixuan Realm's grade all at once.

Still, constant dripping wears through stone—under such feedback, the day would come when the Taixuan Realm became a top-tier Great Thousand World.

Having done all this, Zhang Taixuan finally took out the Ruler of Heaven that Yun Xiao had given him—that is, the Measuring Rod of Heaven and Earth from the Investiture of the Gods world—and began to comprehend it.

This Measuring Rod of Heaven and Earth was no simple thing.

It had been nurtured from one-tenth of the Creation Merit of the Investiture of the Gods world, together with Primordial Qi, making it an extraordinary spirit treasure.

In later ages, Randeng relied precisely on this item, together with the twenty-four Calming Sea Pearls, to evolve the Twenty-Four Heavens and become the Burning Lamp Buddha of the Western Sect.
