There is no doubt that from the dialogue, we can know that this old Tao is the Daozi of the Instrument Sect.

Even if he was in Tianzhou, he was also a top refining great master, and others thought that Lu Daozi had returned to Tianzhou, but they never thought that he was still in the Cold Sword Gate, and he was in this Heavenly Palace.

"Junior's competition, we really shouldn't participate, Elder Fei, it's good for you to pay attention to this matter secretly, don't interfere, no matter whether you win or lose, it will be good for our refining instrument peak and for Senior Lu's instrument sect. Disciple, if you don't hone your cultivation, how can you improve your cultivation and state of mind?" Li Qingyun obviously saw the problem very thoroughly.

Although Elder Fei had very high qualifications and realms, in front of Li Qingyun and Lu Daozi, he could only answer respectfully.

Needless to say, Li Qingyun said that Lu Daozi, who was recognized as a great master of refining, had reached the realm of refining.

Even among the upper sects, the Great Grandmaster of the Earth Realm Refining Weapon can also call the wind and rain, not to mention, the cultivation of Lu Daozi's predecessors is already in the late stage of the Yudan.

Maybe in a few years, it may be possible to touch the Yuanying realm.

After Elder Fei reported the matter, he said goodbye and left, and in the main hall, only Lu Daozi and Li Qingyun remained.

"Senior Lu, inviting you to come this time is also a helpless move, all because of this Heaven Sealing Sword, I'm afraid it won't last long. Li Qingyun said at this time, and after speaking, his eyes swept to the fragment of the Heaven Sealing Sword floating in the center of the main hall, and his tone was helpless.

Lu Daozi also nodded: "After my observation during this time, the reason why the Fengtian Sword is difficult to repair is because there is a big secret hidden inside. ”

"What secret?" Li Qingyun was stunned for a moment, and hurriedly asked, his refining realm only reached the Xuan realm, and naturally it was not as good as the refining level of Lu Daozi's realm, so there were some things that he couldn't see, but Lu Daozi could see it.

Lu Daozi thought for a while and said: "I have just seen this matter, you know why this Heavenly Sword is obviously only a top-grade Xuanyin, but it is so difficult to repair, even if your refining realm reaches Xuanyin, it is difficult to repair, there are things in it that you don't know." ”

Then, Lu Daozi said: "This heavenly sword contains the sword marrow, which used to be the earth realm sword marrow, but for some reason, it was sealed in the Xuan Realm magic sword, if the magic sword is not broken, then everything is fine, but the magic sword is so broken, if you want to seal this sword marrow into the Xuan Realm magic sword again, the difficulty can be imagined, because of this, you have no way to take it all these years." ”

"Earth Realm Sword Marrow?" Li Qingyun was also taken aback, how could he have thought of this, within a Xuanyin Superior Grade Realm magic sword, there would actually be a Earth Realm Sword Marrow, it was simply incredible, and it even deviated from the basic rules of refining.

At least in Li Qingyun's mind, this kind of thing is impossible to do.

"Do you think it's impossible? But it just happened, Qingyun, when you were studying outside, I told you, don't take the words in some classics as laws, refining weapons, there is never any law to speak of, everything is possible, laws and writings, those are all written by predecessors, but you think, what about before predecessors? Is there any rules and laws? No, so don't stick to the rules and be constrained by some rules and regulations, but if you look at you over the years, you haven't listened to what I said back then. Lu Daozi taught again at this time.

If it was before, Li Qingyun would have felt impatient, but this time, he didn't have that kind of thought.

Because facts speak louder than words, there is no mention of this kind of thing in any of the works of refining, and if the essence of a higher-level sword is placed into a low-level magic sword, won't the magic sword be scrapped because of this?

The Heaven Sealing Sword has been used in the Cold Sword Gate for hundreds of years, and there is no problem, and it is powerful, known as the first sword in the Xuan Realm, even more powerful than some Xuanjin-level magic swords.

At that time, I thought it was because the Fengtian Sword itself had six magical powers, but now it seems that it is because of the sword essence of the realm.

"Dare to ask Senior Lu, what level is the sword essence of this realm?" Li Qingyun sorted out his thoughts and asked again.

"Copper is inferior!" Lu Daozi finished speaking, and Li Qingyun took a deep breath.

Copper subgrade?

Even within the Ping Sect, I am afraid that there is no such powerful magic sword essence.

Feng Tianjian actually has such a secret, it is really unimaginable, the specific situation, Li Qingyun does not know, maybe the head Su Ji knows, but he needs to ask again.

Right now, Li Qingyun felt that he should ask Lu Daozi to see if it was possible to repair the Heaven Sealing Sword, after all, Lu Daozi was the Great Master of Earth Realm Refining, and if he could make a move, he should be able to repair the Heaven Sealing Sword.

However, Lu Daozi seemed to see Li Qingyun's thoughts, and immediately said: "Qingyun, I can't fix this sword." ”

Li Qingyun was taken aback, but after all, he was the first seat of the Refining Weapon Peak, and he still had the basic concentration, so he hurriedly calmed down his mood, got up and bowed, and then said: "Senior Lu, if you have any difficulties, you can inform Qingyun." ”

Lu Daozi said with a smile: "It's not difficult, originally, I want to repair this magic sword, but the problem is that this sword marrow has reached the stage of running out of oil and drying up, I can repair the magic weapon, but I can't save this dying sword marrow." ”

Only then did Li Qingyun understand what the problem was.

The sword marrow of the Fengtian Sword is not only the lower grade of the earth's copper, but also has reached the stage of dying, and the refining classics say that the sword marrow, stored in the magic sword above the Xuan Realm, is the essence of the sword, where the sharp qi is, the sword marrow is like a living soul, if the body is damaged, there is a saying of death, the sword marrow is dead, and the magic sword is destroyed.

When he reached the realm of Li Qingyun, he naturally knew the sword marrow, and the sword marrow only existed in the magic weapon-level magic sword, that is, the sword marrow would be produced in the magic sword of the Xuan Realm.

Under the Xuan Realm, even if it is a golden magic sword, there will be no sword essence.

With and without the sword marrow, the power is naturally incomparable, but Li Qingyun knows the grade of the sword marrow and has other knowledge, but he doesn't know how to treat the sword marrow if it is damaged or dying.

It's not that Li Qingyun is not proficient in learning, he can become the first of the Cold Sword Gate Refining Peak, and the knowledge on the refining weapon is naturally undoubted, the problem is that in any classics, even in ancient books, there is no way to treat the sword marrow.

I don't have any knowledge of this.

What Lu Daozi said should also be because of this reason, so even if it is a great master of earth refining like Lu Daozi, there is no way at this moment, perhaps, the method of repairing the sword essence is very simple, but if it is not, it is in vain.

As the saying goes, those who are difficult will not, and those who will will not be difficult.

"I understand, Senior Lu, if there is no way to solve the matter of the sword essence for the time being, then please ask the seniors to help me more in the past few days, and I also have to go to the head of my faction to clarify this matter. Li Qingyun took a deep breath and spoke.

"Yes, the sword marrow is damaged, and the method of repair is not recorded in any ancient books and refining classics, this matter is indeed difficult to do, you must also have a mental preparation. Lu Daozi's meaning is to let Li Qingyun know that maybe they can find a way, but it is more likely that they can't find a way.
