There were some gray stone carved tables and chairs in the hall, and some fist-sized cyan runes were slightly messy on the surrounding walls, and from time to time they emitted a faint spiritual light, illuminating the entire hall brightly.

On a yellow futon in the corner of the hall, a gray-robed man was sitting on it with his eyes closed, and his mouth was full of righteous thoughts.

At the same time, a small cyan sword with a length of time was constantly changing with the sword technique in his hand, and it kept hovering back and forth above his head.

A thick but gentle blue light emanated from the small sword, and a giant head of a green dragon the size of a foot was slowly outlined in the void.

Seeing this, Liu Ming naturally didn't dare to disturb, so he could only stand quietly at the entrance of the hall and watch this scene intently.

This kind of secret technique of using the sword qi wrapped around the flying sword to paint seems to be commonplace, but it is by no means so easy to control the proportion and direction of the entire sword qi.

After half a cup of tea, a cyan dragon three or four feet long appeared vividly in the hall and circled in it.

But after only a few breaths, as the gray-robed man's eyes suddenly opened, he pinched the sword trick with one hand, and spat out the word "receive" in his mouth.

The dragon head in the void had a bright eye, and a "poof" sound came, and the cyan dragon three or four zhang long turned into a faint blue light and dispersed, and the small sword hovered in the void, and disappeared in a flash.

Only then did the gray-robed man stand up, beckoned to Liu Ming with a slight smile, and after signaling him to pass, he sat down on a nearby stone chair.

"Liu Ming, meet Elder Taishang. Liu Ming stepped forward and saluted respectfully.

"Master Liu's nephew doesn't have to be so polite. Actually, this time you are called. The main thing is to use a kendo secret technique in the old man's hand in exchange for half a bag of Xinghe sand in your hand. The gray-robed man said bluntly.

"The disciple has already heard the master mention this matter. Liu Ming replied respectfully.

"Xinghe Sand is a rare refining material. The old man has been looking for a long time, but I didn't expect you to get a bag from the Heavenly Gate Secret Realm this time. Speaking of which. The secret technique of the kendo that the old man used to exchange Xinghe Sand with you this time is also related to this thing, which is a secret technique that can integrate Xinghe Sand into the Yuan Ling Flying Sword through special means. In this way, not only can the power of the flying sword be greatly increased and new supernatural powers can be generated, but more importantly, it will also allow you to try refining sword pills without waiting for the advanced true pill. The gray-robed man chuckled and said slowly.

"What, you can sacrifice sword pills below the True Dan?" Even though Liu Ming had always been calm, he couldn't help but lose his voice when he heard the words.

You must know that once the Yuan Ling Flying Sword is refined into a sword pill. has already broken away from the scope of the prototype of the magic weapon, and has become a real magic weapon, not only is it unpredictable from now on, but the power is immediately very different from before.

However, because of this, if it is the prototype of other types of magic weapons, it is possible to advance the real magic weapon below the True Pill, but the Yuan Ling Flying Sword is almost impossible.

Not to mention anything else, but the terrifying sword intent that emanated from the refining of the sword pill was not at all something that the sword cultivators below the True Dan could control.

Therefore, only those above the True Pill can refine the Sword Pill. This is also something that almost everyone knows in sword cultivation.

The Heavenly Phenomena Realm Secret Elder in front of him actually said that there was a secret technique that allowed him to refine the sword pill below his True Pill, how could he not surprise Liu Ming.

And according to Liu Ming's original plan, it was naturally the queen of the condensation of the true pill. I was ready to start refining the sword pill. Otherwise, it wouldn't have refined the Void Sword Bag in advance.

After all, once the sword pill is refined, it needs to be sealed in the sword bag for decades to nourish it before it can really be completed, and during this time, it is impossible to use the Yuan Ling Flying Sword, otherwise the previous cultivation will be all wasted. It must be sealed again to moisturize.

However, if he had this secret secret, he would be able to refine this sword pill before condensing the True Pill. can make its strength increase instantly.

"Such an exchange, I don't know if Master Liu's nephew is willing? This will not force you to do so. The gray-robed man did not directly answer Liu Ming's question, but looked at Liu Ming and said lightly.

"Of course the disciple is willing!" This time, Liu Ming only thought about it for a while, and immediately agreed respectfully, and turned his hand over, took out a gray cloth bag from the Sumeru ring, and placed it on the stone table in the hall.

With a "bang", the gray cloth bag fell heavily on the stone table.

The gray-robed man grabbed it with one hand casually, slapped the cloth bag in his hand and shook it gently, and heard the sound of the sand particles colliding with Suosuo, and at the same time, the mouth of the bag was released with a "bang", and a ray of bright starlight scattered out of the cloth bag.

Then he took out some gravel from the sack, rubbed it twice in his hand, and examined it carefully before his eyes, his eyes getting hotter and hotter.

"Sure enough, it's Xinghe Sand!"

The gray-robed man burst out laughing when he finished checking it, and at the same time turned his hand and took out a lilac vial and put it aside, flicking his finger at the cloth bag.

A golden glow swept out, the golden light flashed in the cloth bag, and a ray of starlight slowly flew out from the cloth bag, as if the Milky Way was involved in the lilac vial.

After a while, the gray-robed man stopped in his hand, and after gently stroking the lilac vial into his pocket, he nodded with satisfaction, and handed the remaining half of the bag of Xinghe Sand to Liu Ming.

Liu Ming took the cloth bag with both hands, and his divine sense quickly swept the contents of the bag, and after confirming that there was more than half a bag of the remaining Xinghe Sand, he carefully put it into the Sumeru ring again.

"Since the old man has accepted your Xinghe Sand, this secret art will be handed over to you in exchange. The gray-robed man said, taking out a slightly tattered pale blue book from his sleeve robe and throwing it to Liu Ming.

"Thank you, Elder Han!"

Liu Ming stretched out his hand to take the classics, and after a rough flip through them, he found that most of them were related information about smelting flying swords, and some of the handwriting was still fresh, as if it had only been added for a long time, like some experience notes.

"This book is based on my knowledge of a variety of related secret techniques, which I call "Galaxy Fusion Sword Technique". Originally, the refining materials were integrated into the Yuanling Flying Sword, and at least they could only be carried out after refining them into sword pills, but Xinghe Sand is no better than ordinary materials, and you can know the mystery of it as soon as you look at this classic. In addition, this seat reminds you that although after merging into the galaxy sand, this Yuan Spirit Flying Sword can conjure up layers of galaxy power, which is infinitely mysterious, and its power will also increase greatly, but if it is integrated too much, I am afraid it will backfire and affect the spirituality of the flying sword. According to the old man's estimate, only a tenth of the half bag is left. As for the matter of refining sword pills, you can go to the Hidden Scripture Pavilion to check some relevant scriptures. The gray-robed man got up and said a few words to Liu Ming lightly, then turned around and walked towards a stone door at the back of the hall.

"What Elder Taishang said, the disciples should remember. Liu Ming naturally nodded again and again.

"You have extraordinary kendo qualifications, if you have any questions about swordsmanship cultivation, you can always come and ask me. Okay, I'm a little tired, you can step down. After the gray-robed man gave Liu Ming another command, he said the words of sending off the guest.

"Thank you, Elder Taishang!" Liu Ming was overjoyed when he heard this, and immediately did not dare to stay longer, and after putting the book in his sleeve, he left the hall with a deep bow.

After he walked out of Elder Han's cave mansion, the gray stone gate behind him slowly closed again, and the cyan giant sword on the stone door flickered again, releasing bursts of soft sword qi.

At this time, Liu Ming only felt that the Void Sword in the sword bag on his waist had a faint resonance with it, and it trembled slightly.

So he didn't leave immediately, but stroked his waist with one hand, and the pale silver sword bag flashed out, and a golden light shot out from the sword bag, and circled in front of the stone gate.

It lasted for about half a quarter of an hour, but the cyan sword qi above the stone gate only collided gently with the pale golden sword qi released by the Void Sword, but nothing else happened.

Liu Ming couldn't figure it out for a while, and then used his sword finger magic power, releasing a series of invisible sword qi to make a test, but he still couldn't appreciate the subtlety, so he shook his head helplessly, put away the golden sword, and at the same time, with a spell, a black cloud rose from the bottom of his foot, and broke through the sky in the direction of his cave.

At the same time, in the secret room of the cave where Elder Han was, the gray-robed man was sitting cross-legged, playing with the lilac vial in his hand.

"I just heard that Liu Ming's Yuanling Flying Sword attribute is a bit special, but I didn't expect it to trigger the ban on my stone gate, it seems that it should not be underestimated. For hundreds of years, only the flying sword of the scorching sun could reach this level without refining it into a sword pill, and it was a pity that Liu Ming did not join the Heavenly Sword Peak to concentrate on cultivating swordsmanship. ”

After the gray-robed man muttered a few words, he put the lilac vial in his hand into his sleeve robe, closed his eyes, and recuperated.

An hour later, Liu Ming returned to his cave.

As soon as he closed the door of the cave and activated all the prohibitions, he plunged into the secret room again, and couldn't wait to take out the "Galaxy Melting Sword Technique" classic given to him by the gray-robed man, and study it carefully.

It was a full half hour before he put the book aside, his brow furrowed slightly, revealing a thoughtful look.

According to the records of this classic, this kind of secret technique of integrating Xinghe Sand into the flying sword is not complicated, you only need to learn a unique fusion secret technique recorded in the classics, use the sword qi to carry out some special treatment of Xinghe Sand, and then use the sacrificial refining array to integrate it into the Yuan Ling Flying Sword.

However, this method of integration must be done all at once, and it cannot be integrated repeatedly.

As the previous Elder Han said, the amount of the weight of the fusion into the galaxy sand will directly affect the magic power of the flying sword after integration, if the weight of the integration is too much, the power of the stars attached to it will instead lead to the escape of the flying sword's sword qi and affect its power.

The tenth of what Elder Han said was only an approximate weight, not very accurate, which really gave Liu Ming a little headache.

But fortunately, he can use the Phantom Pupil to refine it repeatedly, and accurately consider the appropriate amount of this galaxy sand that needs to be integrated.

As soon as he thought of this, his heart widened slightly, and he carefully flipped through the books in his hand again. (To be continued......)
