Chapter 1502: Sword World, Dao Companion-Birth Master-Acknowledgment Method (3/5, seeking subscriptions)

The Zhu Immortal Sword sensed it and automatically flew up, evolving into a streak of sword-light that flew out of the Taixuan Realm.

Zhang Taixuan felt a faint response, then saw that within the Taixuan Sword Dao imprint, the sword dao edge had grown sharper — that was unmistakably the light of the Zhu Immortal Sword.

The Zhu Immortal Sword's move was certainly not to steal the spotlight, but rather a higher-level method of acknowledging its master.

There are several ways for a spirit treasure to acknowledge its master:

One, bloodline acknowledgment.

Two, soul acknowledgment.

Three, unity of person and treasure.

Four, Dao companion-birth.

The first three methods can be used by ordinary cultivators as well.

Only the fourth — even a saint would not qualify to use it.

Pangu and the Pangu Axe are an example of the fourth.

This method of acknowledgment is exceedingly wondrous: a companion-born spirit treasure basically cannot be seized. So long as the master returns, no matter how thoroughly you refine another's spirit treasure until it obeys your every thought, no matter how perfectly it fits you, the owner can recall it with a single thought.

Even if you shatter another's spirit treasure and refine it into several spirit treasures, you still cannot escape the owner's recall.

This is the highest method of refining a spirit treasure beneath the 17 Daos.

Unless one transcends the Dao, no one can break this rule.

Of course, once one transcends the Dao, there is naturally no need to do so.

One could say this method of spirit-treasure acknowledgment is, in theory, one hundred percent secure.

As for cases like Zhenyuanzi and the Earth Book, or Donghuang Taiyi and the Donghuang Bell — though they seem to be companion-born with their spirit treasures, in truth the treasures merely shared their birth, with no deeper bond; it is simply the unity of treasure and person.

Once the spirit treasure is seized, recalling it is probably hopeless.

"So it seems this Zhu Immortal Sword isn't something belonging to some top-tier demon god." Zhang Taixuan looked at the Zhu Immortal Sword, his gaze subtly amused.

Now that he knew the Dao companion-birth method, he truly feared the demon god's return and recalling the spirit treasure away.

The Zhu Immortal Sword — he had spent so many resources forging it; if it were recalled, wouldn't that be a total loss?

Fortunately, such worry was unnecessary.

Now this sword shared a Dao companion-birth bond with him; beneath the Dao, this sword was one hundred percent his.

He had a feeling that even if he tossed this sword into the chaos and let it drift for countless years, he could still recall it with ease.

"Go."

At a thought, the Zhu Immortal Sword trembled lightly, then flew out of the Taixuan Realm and into the chaos.

Zhang Taixuan certainly was not doing this as an experiment to see whether he could recall a spirit treasure after it had drifted away — he wanted to open up a world and verify his understanding of sword dao.

Within the Taixuan Realm, the Western Fantasy World was to verify his own laws.

The Fire World was likewise for his own laws.

Now that his sword dao law had advanced to the Heavenly Dao realm, surpassing the Primordial realm, he naturally had to verify it.

What is learned from books is ultimately shallow; to truly know a thing, one must do it oneself.

Though laws can be comprehended in the heart, without verification, it is ultimately an unreliable approach.

Whether refining spirit treasures, opening up worlds, or fighting — all are the best paths to verify laws.

Within the chaos, the Zhu Immortal Sword stood towering, like a majestic sword-mountain.

The next moment, the sword-body trembled, and instantly, great waves surged within the chaos.

A world slowly took shape beside the sword-body.

Small-thousand… mid-thousand… great-thousand…

In Zhang Taixuan's view, it was only an instant, but within the chaos, centuries had actually passed.

That world ultimately became an initial-stage great-thousand world.

Within the world, all manner of things were slowly coming into being.

However, unlike the Taixuan Realm's main law — which was the fusion of all Daos — that world's main law was the sword dao law; the other laws were derived from sword dao.

The same fire-type law, when evolved from sword dao, inevitably carried a few extra threads of fierce, killing edge.

The same water-type law, when evolved from sword dao, also gained a few threads of sharp, blade-like breath.

Even the fish in the water had bones like metal — hard as iron, bright as white iron — a strange material.

One could say this world was saturated everywhere with the imprint of sword dao.

"Sword dao is still somewhat unrefined; if truly refined to the utmost, a world evolved from sword dao should be no different from an ordinary world — only easier for comprehending sword dao."

Zhang Taixuan comprehended the laws of the sword-dao world, cross-checked them against his own comprehension, and finally sighed with feeling.

Even for a genius like him, once he comprehended a law, there would still be some errors.

If it were someone else, having comprehended a law and wanting to evolve it to the utmost — who knows how many tribulations they would have to endure.

This is also why cultivators across the myriad heavens find the higher they go, the harder cultivation becomes.

At low realms, with extraordinary comprehension, one can break through in a day — accomplished in a single stroke.

At high realms, even after comprehending, turning it truly into one's own still requires a long process.

Zhang Taixuan's gaze fell on the world; he thought for a moment, and ultimately did not destroy it to reopen anew.

Although this world, due to the laws being unrefined, had developed some errors.

It was precisely because of these errors that this world gained its own character.

For Zhang Taixuan, this bit of character was of no use, but for the beings within, the benefits were boundless.

Like those white-iron-like fish bones — for low-level cultivators, they are a decent material for refining swords.

Like certain trees containing metallic-iron properties — also a divine material for refining swords.

Some water containing metallic properties can even be refined into swords of myriad transformations.
