To the southwest of the Heavenly Sword Mountain Range, there is a vast land, and this land is a high-level dynasty called the Ming Dynasty.

The Ming Dynasty, although located on the edge of Antarctica, is a livable place with beautiful scenery and pleasant climate.

On the edge of the Ming Dynasty, there is a mountain range, which is connected to the Tianjian Mountain Range, but compared to the Tianjian Mountain Range, it is inferior by three points, so it is called the Earth Sword Mountain Range.

On a steep peak in the Earth Sword Mountain Range, Mu Feng sat cross-legged, his hands were sealed in front of him, his eyes were slightly closed, his chest was undulating, his breath was stable and powerful, and in his body, there was also a suction force swept away, so that the mysterious energy between heaven and earth was gathered at an extremely fast speed and poured into his body. With the absorption and refining of the Xuanli energy, Mu Feng's breath is also slowly improving.

"Whew!"

This kind of cultivation lasted for two hours before it ended, Mu Feng slowly opened his eyes, exhaled a slightly cloudy white gas, and a smile appeared on the corner of his mouth, these two hours of cultivation seemed to make his cultivation a lot better.

After coming out of the sword mound, Mu Feng took leave from Elder Lin Yan and came to the Ming Dynasty, and after some travel, he finally chose the Earth Sword Mountain Range as the place to unlock the first seal of the Xuanling Sword.

This mountain peak, the terrain is steep, there are fierce monsters infested in the mountain, there are few human tracks, it can be regarded as secluded and safe, as a place to lift the seal, it is also very suitable.

"Qingyu ......," Mu Feng called softly.

Qingyu's figure also followed Mu Feng's voice. Slowly appeared in front of him, and then asked with a smile, "Ready?"

Mu Feng nodded, and flipped his palm. It was to take out the Xuanling Sword, the Remnant Sword and the tip of the sword, and under the effect of soul power, they were all suspended in front of him.

"Qingyu, when are you going to tell me about the origin of the rune and the Xuanling Sword?" Mu Feng frowned slightly, but he couldn't help but ask.

Now he has too many doubts in his heart, and this qiē, Qingyu knows the answer. But I don't know why, Qingyu just didn't tell herself, which also made De Mufeng a little puzzled.

"Wait until your strength reaches the realm of the Martial Sect. I'll tell you some more things, and if I tell you now, I'll only hurt you, and I know too much. It's not good for you. Qingyu smiled faintly. Road.

Mu Feng was speechless, every time he took the initiative to ask Qingyu, Qingyu would use this reason to prevaricate himself.

"Isn't it the realm of the Martial Sect? in less than a year, I will be able to reach it. Mu Feng said fiercely, now that his cultivation is in the middle of the Freedom Realm, it is not difficult to break through to the realm of the Martial Sect within a year.

Qingyu smiled and didn't answer. His gaze swept over the Xuanling Sword, the Remnant Sword, and the tip of the sword, and then waved his big hand lightly. An invisible force made all three float in front of him.

"What do I need?" Qingyu said lightly.

Mu Feng's mind moved, and hundreds of materials flew out from the Void Stone, and then densely suspended in front of Qingyu's body. These materials are all very valuable, and some of them are extremely rare, and they were also obtained by Mu Feng at a great cost according to Qingyu's requirements.

Qingyu swept his eyes, and nodded with satisfaction, and all the materials he asked for were also collected by Mu Feng.

"Can we begin?" Mu Feng said, unlocking the first seal of the Xuanling Sword, with his own strength, there is no way to do it, so he can only rely on Qingyu to make a move.

"Look at it well, it's not a small benefit to you. ”

Qingyu said with a smile, and immediately sealed his hands, and a transparent flame condensed out, and then with a slight cry of Qingyu, it was divided into more than a hundred flames, wrapping all those materials.

Seeing this scene, Mu Feng's eyes also swelled with a thick color of shock, and when he felt the soul fire condensed by Qingyu, he could see that the huge gap between himself and the latter was as difficult to cross as a moat.

Seeing that Qingyu was refining hundreds of materials at the same time, and it seemed to be relaxed, calm, and easy, Mu Feng was also a little eye-opener, his eyes kept staring at Qingyu, and he didn't even dare to blink his eyes.

Mu Feng also cherished this opportunity to observe, after all, Qingyu made very few shots, and Mu Feng also knew that Qingyu's cultivation in terms of soul masters, even if it was a Tai Qiao'er of Qingcang Mansion, I am afraid that it was inferior, and having such a good opportunity to observe would also be of great help to his level of treasure refining.

Hundreds of materials, under the refining of the soul fire, also turned into a cloud of colorful material liquid at a speed that was visible to the naked eye, and under the delicate control of Qingyu, not a single material was refined.

Mu Feng's eyes have been watching Qingyu's movements, and he has seen Qingyu's every move in his eyes and remembered it in his heart.

Just by seeing the process of refining the jade materials, it all made Demufeng feel that he had benefited a lot, and the power of fine control and the timing of the flame temperature made Demufeng amazed.

Don't look at the refining materials, it seems to be a simple thing, but in fact it is not easy, the quality of the refining of materials is directly related to the success of the later spirit pattern drawing, especially the quality of the material refining, which directly determines the level of the spirit pattern spirituality, thus indirectly affecting the strength of the spirit treasure spirituality.

"It is worthy of being a grandmaster-level character, and I can't beat it up with such a refining technique. Looking at Qingyu's skillful movements and relaxed expression, Mu Feng secretly marveled.

"Hehe, you're still young, and with time, I'm sure you'll be able to surpass me. Qingyu seemed to see what Mu Feng was thinking, and said with a faint smile.

Mu Feng didn't expect that Qingyu was refining hundreds of materials at the same time, and he could also separate his mind to talk to himself, and his face was even more wry, if he wanted to achieve this kind of Qingyu, I am afraid it would take a long time.

However, even if Qingyu is a grandmaster-level figure, after all, there are many materials that need to be refined, and some materials are really difficult to refine, so the materials refined this time also lasted for several hours.

After refining, Qingyu also stopped talking to Mu Feng, and Mu Feng rubbed his somewhat sour eyes, and then looked at this refining again.

He also knew in his heart that this kind of observation opportunity was of great benefit to him, and he could not waste the opportunity in vain.

After nearly five hours of refining, all the materials have been successfully refined, but I have to say that refining materials is an extremely tedious and boring job, but fortunately, Qingyu has reached the level of the Five-Star Soul Sect, even so, there is still no fatigue.

Mu Feng asked himself, if these materials are allowed to be refined, regardless of the success rate, I am afraid that it is impossible to complete it without three or five days, and Qingyu only took five hours to complete the refining, this speed is really terrifying.

After the refining was over, Qingyu spent seven hours drawing the clumps of material liquid into spiritual patterns, and put them aside for later use, and then looked at the remnant sword and the tip of the sword.

As soon as Qingyu's heart moved, the soul flame wrapped the remnant sword and the tip of the sword into it, and its raging flames made De Mufeng feel palpitations, if this soul flame fell on his body, I am afraid that he would be turned into ashes in an instant, and even the Yuan Shen could not escape.

Under the fierce scorching of the soul flame, the remnant sword and the tip of the sword began to melt in a very short period of time, and faintly, a small black sword several inches long emerged. When the black sword appeared, Mu Feng could feel that an extremely powerful wave swept out from the black sword.

After the appearance of the black sword, the Qingyu handprint changed rapidly, and one seal after another hit the Xuanling Sword, and at the same time, the spiritual patterns were also covered on the Xuanling Sword in a certain order.

As the spirit patterns were immersed in the Xuanling Sword, ancient and obscure runes seemed to appear on the body of the Xuanling Sword, and these runes, like shackles, bound the Xuanling Sword.

However, with the immersion of the spirit patterns one after another, these runes seemed to be weakening a little bit, and at the same time, the aura emitted by the Xuanling Sword also slowly became stronger.

When all the spirit patterns were immersed in the Xuanling Sword, Qingyu changed the printing method again, and with a wave of his big hand, the black small sword also quickly sank into the Xuanling Sword.

And with the submersion of the black sword, the ancient and obscure runes on the Xuanling Sword all melted away, and a black ripple visible to the naked eye suddenly swept out and rose to the sky!

At the same time, a rather terrifying spiritual fluctuation enveloped the entire mountain.

Mu Feng felt this spiritual fluctuation, and then looked at the Xuanling Sword, and there was a thick shock in his eyes.

At this time, the Xuanling Sword, compared with the previous four and a half feet, the sword body has increased by one foot, and it has reached five and a half feet, and the width of the sword body has also increased. On the sword body, the black sword body flashed with strange red patterns, which looked a little weird and hideous.

At this time, the Xuanling Sword was heavy and hideous, like a awakened beast, giving people a sense of palpitations, and the spiritual fluctuations emanating from its body did not know how much stronger it was than before.

Obviously, the first seal of the Xuanling Sword has been completely unlocked, and the grade of the Xuanling Sword has also completely changed from a high-grade spiritual treasure to a mid-grade spiritual treasure in the ground level.

Mu Feng didn't come back to his senses for a long time, this is to unlock the first seal, if the second and third seals are unlocked, I really don't know what kind of terrifying Cheng Xuan Ling Sword can achieve.

"Hehe, it's done!" Qingyu smiled faintly, and then glanced in a certain direction, and said, "I just didn't expect that this Xuanling Sword had just been unsealed, and someone had sent it to the door to test the sword." (To be continued......)
