After the opening, there is a myriad of material knowledge.

In this book, there is no distinction between spirit grass or ore or anything else. Everything in the World Book is part of the world that makes up the universe.

Starting with the most inconspicuous grass and an ordinary piece of dirt, this book has it all.

Fortunately, the things in this book are also divided into hierarchical levels, and the introductions are all arranged from low to high. The division of high and low levels is not said in the book, Di Jiu guessed that it should be according to the distribution of aura, hardness and other factors.

According to the World Book, all matter is tangible, but tangible matter is divided into high and low according to different rules.

Di Jiu had seen too many kinds of spiritual herbs and medicinal herbs. After he began to study the book, he realized that what he had known before was simply superficial knowledge.

Di Jiu read the contents of this book hungrily, his mind was powerful, and his reading speed was extremely fast, but after a few days had passed, he was still lingering on the first page.

If it weren't for seeing Zisa Sha in the World Book, Di Jiu would have read it like crazy.

After seeing Zi Sasha's introduction, Di Jiu suddenly woke up.

Zisa Sand is indeed a ninth-level material, but this ninth-level material is somewhat similar to Heavenly Sword Essence Gold, because this material can also be promoted after being refined into a magic weapon.

Moreover, there is definitely more than one Heavenly Sword Essence Gold that can be refined together with Zisa Sha to become a promotion magic weapon. In this respect, the Purple Sa Sand is more precious than the Heavenly Sword Essence Gold.

Zisa Sand also has a characteristic, that is, if you want to get a higher level of Zisa Sand, you must first refine Zisa Sand into a magic weapon. Let the magic weapon advance, when the magic weapon is promoted to a certain level, then decompose the purple sand in the magic weapon to get a higher level of purple sand.

This method can only be done by those who use magic weapons, that is to say, if you want to separate a higher level of Zisa Sand, first of all, your Purple Sand upgrade magic weapon must be refined by yourself, and secondly, the magic weapon you refine must also be used by yourself. Only when these two conditions are met, will you be able to separate the Zisa Sand into a higher level of Zisa Sand in the future.

Di Jiu didn't care about these characteristics of Zisa Sha, what he cared about was that he himself was a Zisa Sha, and he didn't know it before.

It was a stone ball obtained in the cave of Andromeda, and the extremely heavy stone ball was a purple sand.

After knowing that he had purple sand, Di Jiu was a little eager to find a flame and refine his magic weapon first.

As for this world book, you can read it at any time. With his current cultivation, in another 10,000 years, I am afraid he will not be able to finish reading this book.

Di Jiu was about to withdraw his divine thoughts and leave, when he suddenly thought. Before, the gray-clothed monk said that the monk's divine thoughts could not touch the world book, but now with the help of the gray stone, his divine thoughts not only came into contact with the world book, but even the contents of the world book could be seen clearly.

Doesn't that mean that he has a chance to refine this world book?

At the thought that he could refine the World Book, Di Jiu could no longer hold back the wild beating in his heart. He has not yet calmed down to the fact that the world book in front of him may belong to him, and he is still indifferent.

The value of this world book Di Jiu was too clear, and he just spied a little bit of it, and he benefited a lot. Once he has refined the World Book, what else can stump him when he walks in the universe?

Refining, must be refined!

Di Jiu no longer continued to read the contents of the World Book, and his divine mind began to look for the prohibition of the World Book, wanting to refine the World Book by refining the prohibition.

After a day passed, Di Jiu was a little dazed.

He didn't find any prohibitions in this world book, but with the help of the gray stone, he found the boundless and infinite rules in the first page of the world.

He knew if it was the rule, or if it was because of the gray stone.

Cultivating to this day, Di Jiu also vaguely understood that the golden lightning in his gray stone seemed to be a rule of heaven and earth. As for what the rules were, he couldn't touch them at all.

The rules on the first page of this world book are boundless, and it is impossible to describe a corner of them with billions.

If he wanted to refine the World Book by understanding these rules, Di Jiu estimated that he would not be able to refine this World Book in countless billions of years.

When Di Jiu was about to give up, the golden lightning in the gray stone in his sea suddenly burst out with mysterious golden lines, and Di Jiu couldn't understand any of these lines, he could only vaguely feel that these golden lines were also one of the rules of heaven and earth.

The endless golden lines almost burst Di Jiu's sea of knowledge. Where did Di Jiu still care about refining the World Book, he hurriedly ran the Xinghe Jue cultivation crazily. He could only hope that through cultivation, he would bring these golden lines from the sea of knowledge to the starry sky.

Originally, although the aura here was sufficient, it was impossible to cultivate at all. Because Di Jiu had the golden pattern rules and absorbed the rich aura here, he quickly completed the first Zhou Tian operation.

With the formation of the first Zhou Tian, Di Jiu absorbed more and more aura, and his cultivation also improved rapidly.

In just half a month, Di Jiu came to the peak of the eighth layer of the foundation building, and then a clear rule aura was caught by him. This aura of rules was felt by Di Jiu through the endless golden lines in the sea of knowledge, and at the same time that Di Jiu felt this aura of rules, his cultivation stepped into the ninth layer of foundation building without half an obstacle.

Following Di Jiu's surprise discovery, one of the billions of rules on the first page of the world book was caught by him, and he even clearly realized it.

At this moment, there seemed to be an additional connection between him and the world book.

It turns out that the World Book is not forbidden to refine, but to refine through this perception of the infinite rules in it.

If there was no gray stone, Di Jiu would understand this truth, and he would not do such a boring thing again. Now, as long as he cultivates, he will have the opportunity to sense the second rule aura again through the golden lines inspired by the gray stone.

After having a direction, Di Jiu sank into this rule of comprehending the world book while cultivating.

Originally, the world book was like a stagnant water, but because of Di Jiu's continuous understanding, the world book also continued to seep out the rules of heaven and earth.

Dozens of monks who felt outside the world book fell into an epiphany because of these heaven and earth daos. Because everyone is having an epiphany, even if Di Jiu unknowingly stepped into the World Book, no one will find out.

......

Half a year later, when Di Jiu caught the ninth rule on the first page of the World Book, the vague gap between him and the World Book suddenly disappeared. Di Jiu was pleasantly surprised to find that there was a half-opened book suspended in his sea of knowledge.

Isn't this the world book? Di Jiu opened his eyes, and sure enough, the world book that had been erected beside him disappeared.

Di Jiu was sure that he didn't refine the World Book, that is, the billions of rules on the first page of the World Book, and he only caught nine of them, and he only felt it, not really enlightened.

So that the world book becomes his?

In just a short period of time, Di Jiu vaguely understood that the World Book appeared in his sea of knowledge, not because he had refined the World Book or understood the rules on the World Book, but because he had gray stones and golden lightning. Because of these two things, the world book should have taken the initiative to appear in his sea of knowledge.

With a clear regular aura and a powerful True Yuan flow, Di Jiu had a feeling that he was about to break through.

Di Jiu knew very well that this was not an illusion, but because in half a year, his cultivation had come to the foundation building consummation, and he had been comprehending various rules, even if he hadn't comprehended any of them until now, he was about to enter the Jindan period.

After looking at the other dozens of monks who were still closing their eyes and not realizing that the World Book had disappeared, Di Jiu stood up and quickly left here.
