The thousand-year-old ice silk is a kind of cicada silk spit out by the fifth-order demon beast, the ice crystal cicada. The formation conditions are very special, it is buried in an extremely heavy place of cold air, it takes thousands of years, and it has undergone abnormal changes, so that it has a very low probability of forming a kind of refining magic weapon of the best material.

Millennial ironwood is a special wood that is equivalent to fine iron after the ordinary ironwood survives the thunderstorm, absorbs the aura of heaven and earth, and grows for thousands of years again. The weight is dozens of times heavier than that of the same volume of dark iron. The strength and hardness are extremely high, and it can withstand huge tensile pressure. It is also a rare good thing.

The "Soul Refinement" in his body was running slowly, and Zhou Nan entered a world of ice and snow for a while, and his whole body shivered with cold. After a while, he entered a steel forest, and his heart was shocked. In the following time, his entire consciousness was constantly shifting between the two spiritual spaces.

Gradually, Zhou Nan's brows fell. After a day of continuous efforts, he has a further understanding of these two ingredients. Although I don't dare to say that I know the roots, I can barely do it just by refining the magic weapon.

Although these two things are not as good as Haotian Stone, Sealing Dragon Coffin, and Hantan Ice Lotus, they are unavoidable and full of spirituality, but they are already the best materials Zhou Nan has ever seen.

There is no one, only the best!

A day later, Fairy Yaoqin had regained her mana, and her long eyelashes moved slightly, and she woke up slowly. Seeing that Zhou Nan was ready, he didn't say anything more, and smiled like a flamethrower, and with just a slight touch, a small flame cast of pure gold fell into the casting furnace. In an instant, it burned into a raging fire. Intense heat. The roasted Zhou Nan's mouth was dry for a while.

He took a deep breath and gathered his mind. Zhou Nan shook his left hand vigorously, and threw the thousand-year-old ice silk into the Danhuo. "Soul Fighting" is spinning rapidly. Zhou Nan kept adjusting the movement of the thousand-year-old ice silk, so that it was fully scorched.

Half a day later, under the continuous burning of the Danhuo, the thousand-year-old ice silk released a strong cold air, and under the sudden raging white cold air, bursts of ice crystals burst out instantly, almost freezing Zhou Nandu.

Seeing this, Fairy Yaoqin playfully stuck out her tongue and hurriedly shot out a mana shield. protected Zhou Nan. As for herself, she didn't care about the cold at all. Before the cold air could get close, it was blocked by an invisible force.

It can be seen that his cultivation is profound and extraordinary.

Rubbing his arm, and after his body recovered its temperature, Zhou Nan took a deep breath, and after heating it again for a while, he lifted it out. It was placed in a special silvery liquid. Suddenly, under the dual action of ice and fire, the silver liquid boiled for a while, and froze for a while. But it has always stood firm and has never been destroyed.

Seeing this, Zhou Nan nodded with satisfaction. I secretly put my heart at ease and started to concoct a thousand-year-old ironwood.

This thousand-year-old piece of ironwood is a single trunk. It is more than a meter long and half a foot thick. At the same time, it is more than 10,000 yuan to make a guqin. Ironwood is extremely tough, and it clangs when it is struck, and to put it bluntly, it is not much different from steel.

For it, there is no need for Zhou Nan to wait as carefully as he did with the thousand-year-old ice silk. Then Danhuo, after burning the iron and wood red, Zhou Nan didn't say a word, and directly rounded his shoulders, carrying the casting hammer is a hammer.

But it's a pity that although Zhou Nan's huge strength can be called terrifying, every time he hits this iron wood, he can only smash a small dent. It seems that it is not possible to knock a whole piece of ironwood into the desired shape.

Three days later, just when Zhou Nan's arms were numb and trembling, and he was about to break from exhaustion, Tiemu finally softened, removed all impurities, and turned into a one-meter-long guqin body. The body of this piano is blackened throughout, the shape is simple, and it flashes with a dark and faint light. Before the person got closer, he felt a heaviness like a mountain.

There is a space behind the piano body, and Zhou Nan spent a lot of effort to chisel out a resonance box. And after the determination of the professional Yaoqin Fairy, it took hundreds of changes to meet the basic requirements of playing beautiful music.

After resting for three days, after Zhou Nan recovered his strength, he took out the basically formed body and threw it into the casting furnace again, beckoning the free Yaoqin Fairy, and played a golden Danhuo, which was quickly heated.

This side has just been arranged, and Zhou Nan is not idle over there. Without interruption, the ingredients that have been purified are prepared according to a certain amount and put into a jar that can isolate the leakage of spiritual energy.

After the body was heated, Zhou Nan put it on the casting table, poured some silver powder from the jar, and sprinkled it evenly on the body. With a delicate little hammer, squinting his eyes slightly, he struck it with precision and force.

The crisp sound of 'ding ding ding' kept coming, and Zhou Nan repeated his actions, again and again. Ten days later, until all the ingredients were knocked in, Zhou Nan wiped the sweat from his forehead with a weak arm and let out a long sigh of relief.

I saw that the current body of the piano has already changed greatly. The unique jet-black color of Ironwood is gone. Instead, there was a cold pale silver, noble atmosphere. Moreover, on the silver body, there are also circles of strange patterns, and the light is flowing, which is beautiful and abnormal, and it is fascinating.

These patterns are the texture of the ironwood itself. When Zhou Nan shoehorned the ingredients into the ironwood according to a certain proportion along these textures, the body of the piano changed color. These textures are revealed against a silver background. Like a beautiful butterfly, flying and hovering on the surface of the piano body, looking at the love of the Yaoqin fairy for a while.

After getting the body of the piano done, Zhou Nan rested for a day, then turned around, looked at the beautiful face of the Yaoqin Fairy, and said with a smile, "Qin Fairy, the body and strings have been refined, what about the fire attribute materials prepared by the fairy?"

Hearing this, Fairy Yaoqin frowned for a while. Although she also hopes that this beautiful piece will be successful, it also means that her free audience is leaving. Therefore, she had a complicated mind, until Zhou Nan urged her again and again. When he almost knelt down and begged her, he reluctantly touched the storage bag on his waist. He took out a fist-sized fiery red crystal and threw it away.

Take the fiery red crystal. In an instant, Zhou Nan's breathing became rapid.

Where is this fire attribute material, it is clearly a fire attribute high-grade spirit stone!

You must know that in today's immortal cultivation world, there is a lack of resources. Although the spirit stones are divided into four grades. Lower, medium, top, best. But the best spirit stone has long disappeared in the long river of history, and it has not appeared for thousands of years. Therefore, it is said that there are four levels. But in reality there are only three.

Therefore, as the top high-grade spirit stone, while it is precious, it is firmly controlled by those ancestors who are high in the infancy of Shangyuan, and it is hidden like a baby pimple. Unless it is a special moment, it will never be taken out and used.

Therefore, the high-grade spirit stone is rare to see in the outside world.

The medium-grade spirit stone is the cultivation of the ancestors in the Dan period. Something that is used, traded, is relatively large. Low-level monks, there is still hope to see it.

As for the lower grade spirit stone. is very common. It mainly circulates in the two realms of enlightenment and foundation. It is the most basic currency in the world of cultivating immortals. The usage is very large.

Although Zhou Nan has seen medium-grade spirit stones, he has also owned medium-grade spirit stones. But for the top grade spirit stones. But he didn't dare to think about anything. But what he really didn't expect was to see such a big piece here today. Now. Under the temptation of the high-grade spirit stone, Zhou Nan was shocked to find that his mind was almost intoxicated by the pure and beautiful fiery red.

Holding the fire attribute high-grade spirit stone, it took a long time for Zhou Nan to stabilize his emotions and study it with a fiery face. The most significant feature of the high-grade spirit stone is that it contains a strong aura. It is tens of thousands of times more than the inferior aura.

Holding it in your hand makes you feel like you're holding a bomb. If it weren't for the fact that the spirit stone was very stable, Zhou Nan would have been a little worried, this guy would have exploded accidentally. The moment he slowly started the "Soul Determination", Zhou Nan appeared in a fiery red space.

But before he could take a closer look, his spiritual sense was burned clean in an instant by the rich fire aura. "Soul Determination" was interrupted, Zhou Nan's face turned pale, and the corners of his mouth flowed red blood. If it weren't for the way he walked and his body was strong, he would have been seriously injured.

At this time, Zhou Nan encountered something that could interrupt his "Soul Decision" for the second time. The first time was the sealing dragon coffin, and the second time was the high-grade spirit stone of this fire attribute. After being interrupted, Zhou Nan did not give up. After healing his injuries, he entered the fiery red spiritual space of the spirit stone again.

Again and again, after going through thousands of times, just when Zhou Nan's tortured heart was sudden, he really couldn't hold on. This fire attribute high-grade spirit stone finally opened that mysterious door to him.

A few days later, the first thing Zhou Nan did after recovery was to enter the fire-red space of the top-grade spirit stone again. In this only fiery world, I observed carefully.

Like the spiritual space within the spirit stone, Zhou Nan had also observed it before. But the spiritual space of this high-grade spirit stone is obviously different from what I saw before, and it is very peculiar.

The spirit stone is the product of extreme compression of the spiritual energy. The spiritual space of the lower grade spirit stone is very ordinary, and it is just comparable to an ordinary spiritual land. The spiritual space of the medium-grade spirit stone, he could also guess that it was not far from ten after the initial inspection. But what will happen to the high-grade spirit stone whose aura has been compressed tens of thousands of times, Zhou Nan couldn't predict it, let alone imagine it.

Zhou Nan is like a curious child, constantly wandering in the fiery red space, observing all the secrets inside. But there are many things that Zhou Nan can only see, but can't understand. His current realm is far from the level of analyzing high-grade spirit stones.

But even so, after having the anti-heaven ability of "Refining the Spirit", Zhou Nan also had the certainty of using this spirit stone refining weapon.

In this way, after some research, Zhou Nan decisively stabbed this high-grade spirit stone. It was cut into fourteen long columnar pieces of various sizes and odd shapes.

Originally, Zhou Nan also planned to fuse fire attribute materials with thousand-year-old ice silk. But after discovering that this fire attribute material turned out to be a fire attribute high-grade spirit stone, he had an idea. simply use this high-grade spirit stone to make dragon gums, as a piano pillar, carrying the strings. As long as it is handled properly, every time you play the strings, it will stimulate the energy of the fire attribute spirit stone. When the time comes, the combination of ice and fire may be able to give better play to the characteristics of the material.

The top-grade spirit stone is very hard, in addition to the exhaustion of the spirit weapon and self-destruction, Zhou Nan really has nothing to do with it. In the end, it was the Yaoqin Fairy who reluctantly made a move, and with the terrifying sound wave that Zhou Nan's scalp was numb again, rubbing, in a few breaths, he cut the entire spirit stone into fourteen pieces of equal size.

The body, strings, and gums were all ready, and Zhou Nan began the last step of fusion. This step is very crucial, and it is the most important link related to the success of this treasure refining.

Before, though, the body and ingredients were fused. But it is mainly based on thousand-year-old ironwood, and the ingredients must be obedient whether they want it or not, and there will be no great rejection. But now it's different, whether the three main ingredients can be combined into one, Zhou Nan is really not sure. (To be continued......)
