Chapter 1502

The Immortal Execution Sword sensed it, and automatically flew up, evolving a sword light, flying out of the Taixuan World.

Zhang Taixuan sensed it slightly, and saw that in the Taixuan Sword Dao brand, the edge of the Sword Dao became sharper, which was clearly the light of the Immortal Execution Sword.

The Immortal Execution Sword doing this, of course, was not seizing the host, but another more advanced way of recognizing the master.

There are several ways for magic treasures to recognize a master:

1. Bloodline recognition

2. Soul recognition

3. Human-treasure unity

4. Great Dao companion

The first three can be used by ordinary practitioners.

Only the fourth one, even saints are not qualified to use.

Pangu and Pangu Axe are the fourth kind.

This recognition method is very mysterious, companion magic treasures basically cannot be taken away; as long as the master returns, even if you refine others' magic treasures to be more spiritual and compatible, others can recall them with a single thought.

Even if you break others' magic treasures into several magic treasures and refine them, you still cannot avoid others' recall.

This is the highest magic treasure refining method under the 17 Great Dao.

Unless you surpass the Great Dao, no one can break this rule.

Of course, surpassing the Great Dao, naturally there is no need to do this.

It can be said that this magic treasure recognition method is theoretically 100% secure.

And such as Zhen Yuanzi and the Earth Book, Donghuang Taiyi and the Donghuang Bell, seem to be companions with magic treasures, but in fact, they are just born with magic treasures, and there is no deeper relationship, just the unity of magic treasure and person.

Once the magic treasure is taken away, wanting to recall it is probably hopeless.

"Looking at it this way, this Immortal Execution Sword is not something from a top demon god." Zhang Taixuan looked at the Immortal Execution Sword, his eyes subtle.

Knowing the Great Dao companion method, he was really afraid that the demon god would return and recall the magic treasure.

Immortal Execution Sword, he spent so many resources to build, if it were recalled, wouldn't it be a huge loss?

Fortunately, this worry was just redundant.

Now this sword has a Great Dao companion relationship with him, under the Great Dao, this sword is 100% his.

He had a feeling that even if he threw this sword into chaos, wandering for countless years, he could easily recall it.

"Go."

With a thought, the Immortal Execution Sword trembled slightly, then flew out of the Taixuan World and arrived in chaos.

Zhang Taixuan of course was not doing an experiment, wanting to see if he could recall the magic treasure after it wandered, but wanted to open up a world and verify his understanding of Sword Dao.

In the Taixuan World, the Western Fantasy World was to verify his laws.

The Fire World was also for his laws.

Now, the Sword Dao Law has progressed to the Heavenly Dao realm, already surpassing the Hunyuan realm, naturally needing to verify it.

Knowledge gained from books is ultimately shallow, one must practice to know the truth.

Although laws can be comprehended in the heart, without verification, it is ultimately an unstable practice.

Whether it is casting magic treasures, opening up worlds, or fighting, they are the best paths to verify laws.

In chaos, the Immortal Execution Sword stood tall, like a towering sword mountain.

The next moment, the sword body trembled, immediately, huge waves rose in chaos.

A world slowly formed beside the sword body.

Small thousand... middle thousand... great thousand...

In Zhang Taixuan's view, it was just a moment, in chaos, in fact, thousands of years had passed.

That world finally became a primary great thousand world.

Inside the world, all things were slowly forming.

However, unlike the Taixuan World where the main laws are the fusion of ten thousand paths, in that world, the main law is the Sword Dao Law, and other laws are evolved from the Sword Dao.

The same fire system law, evolved from the Sword Dao Law, ultimately had a few more traces of sharp qi.

The same water system law, evolved from the Sword Dao Law, also had a few more traces of sharp breath.

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

It can be said that this world was full of the brand of Sword Dao everywhere.

"Sword Dao is still a bit impure, if it were really pure to the limit, the world evolved by Sword Dao should be no different from ordinary worlds, just easier to comprehend Sword Dao."

Zhang Taixuan comprehended the laws of the Sword World, verified them with his own comprehension, and finally sighed.

Even a genius like him, having comprehended the laws, would have some fallacies.

If it were others, having comprehended the laws, wanting to evolve them to the limit, they would not know how many calamities they would have to experience.

This is also the reason why practitioners in the heavens find it more difficult to practice toward the end.

Low realm, extraordinary comprehension, breaking the realm in a day, achieved in one step.

High realm, even if comprehended, wanting to make it one's own, also requires a long process.

Zhang Taixuan's gaze fell on the world, thought for a while, and finally did not destroy it and reopen it.

Although this world had some fallacies because the laws were not pure.

But it was precisely because of these fallacies that this world had its own characteristics.

For Zhang Taixuan, this characteristic was useless, but for the living beings within, it was of infinite benefit.

Just like that white iron-like fish bone, for low-level practitioners, it is a good sword-refining material.

Just like some trees with metal attributes, it is also a divine material for refining swords.

Some water with metal characteristics can be refined into precious swords that change in ten thousand ways.
