After introducing the situation of the Qizong clearly, it was already the third watch, but Xu You and Lu Daozi were not sleepy, after all, neither of them was an ordinary person, Lu Daozi was a major overhaul in the later stage of Jiedan, and his physical body was already invulnerable, not to mention that he didn't sleep all night, even ten days and a half months would not be a problem.

Although Xu You does not have Lu Daozi's cultivation, he is not a mortal, not to mention that there are many magic weapons on his body, just say that he has an incarnation outside the body, and the incarnation of the spirit and spirit can replenish the body, if you really stay up late, I am afraid that even Lu Daozi may not be able to compare to Xu You.

Therefore, Lu Daozi talked about refining weapons from the affairs of the sect.

I have to say that although the mysterious voice is unfathomable, it has a strange temper, and it is not a question that must be answered, Lu Daozi is a genuine realm, he can't wait for Xu You's refining realm to advance by leaps and bounds, of course, he knows everything and says everything, this time, it is exactly what Xu You wants.

Second, because the mysterious voice is of high realm, there are many truths that need to be pondered by Xu You, and it is relatively much easier on Lu Daozi's side, and the way of learning the law needs to be studied from various angles, and Lu Daozi's refining theory can just make up for this.

So sometimes the two of them preached alone, sometimes they asked and answered, and they actually said that the next day was three poles, and they were still not tired.

Lu Daozi may have something to do at this time, so he looked at the time and said to Xu You: "Apprentice, you rushed with me before, and you didn't rest after you came back. ”

Xu You nodded, what Lu Daozi taught him, he also needed time to digest, and then integrate it and learn it for his own use.

Here, there is no need to worry about how to find materials, and there is no need to worry about collecting refining weapons, as long as Xu You needs them, most of them are there.

What's more, Xu You has a secret that only he knows.

That's the Realm.

As long as there is a special boundary key, the Boundary Artifact can open the way to the other world. Just like the corpse world, although Xu You has been trapped in it for a year, he has also gained a lot, and all kinds of refining materials are everywhere.

The corpse key of the corpse realm has already been refined by Xu You, so if you need a powerful corpse to transform into a corpse, or if you want to find some rare materials, Xu You can enter the corpse realm to obtain it, which is extremely convenient.

When Xu You was studying the refining weapon, a letter talisman flew in from the outer door, Xu You saw it, stretched out his hand to take it, took a look, and nodded slightly.

This letter was sent by the old man who devoured the corpse, he came to settle in a certain village and town under this Qizong Mountain a few days earlier than Xu You, and now he is already familiar with the surrounding situation. Sending this letter is to tell Xu You that he has settled down, and if there is a sending, Xu You can directly order him.

Since the corpse-devouring old man surrendered to Xu You, he has also been honest and very loyal. Of course, Xu You will hand over some things to the corpse-devouring old man, but he will not completely rely on and trust the other party.

The old man who devoured the corpse surrendered because he was pinched by himself, and once he let go, it is estimated that the old man who devoured the corpse would choose to flee even if he did not rebel.

Inside the Qi Sect, Xu You would inquire about some things, but outside, he also needed someone to inquire about the situation.

The Old Man is undoubtedly the best choice.

The other party doesn't say how to cultivate, at least he has a lot of experience in training outside, and he can deal with any emergencies.

After writing a letter and sending it out, Xu You took a refining book and looked at the contents recorded on it. If Lu Daozi saw the book Xu You was holding, he would inevitably shake his head and persuade Xu You not to waste time.

It's not that this refining book is bad, but it's because it's too good.

This refining classic talks about the magic weapon of Xuantong, the refining method of the Ruyi Yin Yang Divine Sword, including the origin of this divine sword magic weapon, the materials required, how to refine it, and even some details are described.

But the problem is that this bronze high-grade magic weapon can't be refined at all, not because of the technique and skill, but because of the material.

To refine this divine sword, there is an indispensable material, which is Yin Yang Gengjin Iron.

Gengjin is not difficult to find, although it is also rare, but there must be a flat sect like the Qi Sect, but the problem is not ordinary Gengjin, but the nature of yin and yang.

That's going to be hard.

It can be said that even Lu Daozi has never seen this kind of Gengjin.

The nature of yin and yang is already difficult to see, let alone on the Gengjin that refines flying swords and sword qi, it is even more unheard of.

It is because of the lack of this key, so even if Lu Daozi has the refining method and most of the materials of the Ruyi Yin Yang Divine Sword, he can't refine it.

Xu You looked at the classics, but it was because this Ruyi Yin Yang Divine Sword was too suitable for his clone.

The so-called divine sword, in fact, is just a Gengjin sword qi, the sword qi has no shadow, killing thousands of miles, because of this, it can be called wishful thinking, and the sword rises.

In addition, the magic sword that has reached the Xuan Realm is mostly tangible and intangible, especially this kind of free sword qi, which is even rarer, after ordinary monks refine it, it needs to be stored in the lungs, but the sword qi is sharp, it will hurt the lungs to some extent, and it is difficult to last long, and it will not take long to dissipate. But this Ruyi Yin Yang Divine Sword that Xu You saw was an extremely rare Xuanjing Sword Qi-shaped magic weapon, but it has always existed, changing freely, and it is very wonderful.

Xu You wanted to come to his own clone, in addition to the art of the imperial object is very good, other techniques are not able to surpass others, if there is such a shadow yin yang divine sword sword qi, then the strength will be even better.

The most important thing is that Xu You once saw a method of building a foundation in a classic.

Five Elements Divine Sword Body.

That is the Xuan Realm sword essence that refines the attributes of the five elements, integrates it into the five organs, and then achieves foundation building and cultivation.

It is considered an extremely powerful way to build a foundation, surpassing more than ninety percent of the monks in the world, naturally, Xu You feels that this kind of cultivation will be even more powerful.

Although his body is still unable to cultivate, after the doppelganger cultivates, he hides in his body and exerts his supernatural powers, which is also equivalent to the ontology.

Moreover, with this cultivation method, Xu You also found a great advantage, the doppelganger cultivates, if he encounters a difficult bottleneck, he can actually use the method of refining magic weapons to help the doppelganger cultivate.

This kind of bystander's perspective and means of assistance allow the doppelganger's cultivation speed to increase by one level.

Now Xu You's clone has reached the tenth level of qi refining.

There is only one step away from building a foundation, and in fact, Xu You's doppelganger wants to build a foundation, which can be carried out at any time, but Xu You didn't want to choose an ordinary foundation building this time, so he went through the group books and found a foundation building method suitable for his clone.

That is the Five Elements Divine Sword Body.
