The magic weapon that Yue Yu wanted to refine was inspired by the day he fought Bai Feng at the foot of Furong Peak three years ago. At that time, the most impressive thing for him was Bai Feng's 'Wind Shadow' sword.

Bai Feng was born in Mingzhu Peak, specializing in formation runes, and was not very good at sword control. But the seven-rank Xuan soldier that day still gave him a great threat. The formation uses the formation to urge the air and wind to produce an air cannon and jet-like effect, making the Xuan Bing itself have great lethality.

Therefore, when Yue Yu was at the auction and found this piece of black-veined gold, he immediately thought of the 'Wind Shadow' sword.

――Propelling with compressed air and wind, although the power is also strong, but it is more than one level behind his Great Five Elements Yin Yang Yuan Magnetic Extermination Light Needle and Guangling Absolute Sword, and in the end, it is at most six or seven times the speed of sound, and it is to the limit. The obvious power of refining is far as ...... The treasure is really not necessary.

However, if you use powerful electromagnetic propulsion, the lethality is enough to be several levels stronger!

Suddenly, the lid of the moire tripod was opened, and the mana in Yue Yu condensed into a bundle, and about one was taken out of it. The weight of the human tail finger is black striped gold. Then he violently urged the qi, blood, and soul of the whole body, and after gathering together, he used the method of spontaneous combustion to transform into samadhi true fire. began to burn these black gold.

The consumption of a samadhi true fire is extremely high, and the object of this refining is even more precious. Although it is heat-resistant and strong, it is only equivalent to those top-grade metals.

But it is still not Yue Yu's current cultivation, which can be handled.

However, Yue Yu also has his own advantages. Metals that have been burned by the true fire of Samadhi have their own special atomic crystal structure and arrangement. It can enhance the refiner's ability to sense its mind.

All he needs to do is record it and then draw the cat and tiger in other parts. With this one entry, he could save at least seventy percent of his mana!

It took about three minutes to complete the process. It wasn't until this mass of liquid, induced by his mind, reached the point where it moved at will, like an arm's command, that Yue Yu stopped the samadhi true fire.

This Xuan's Yue Yu was already a little tired. However, then he still didn't dare to relax a little, but put the thunder spirit stone that had been prepared for a long time. and the soul jade thrown in, all of which were integrated into the solution. Then manipulate with mana. After condensing into a needle, while the black gold was still cold-cut, he began to carve runes on it with divine thoughts.

Since I got this black gold that day, I planned to refine this magic weapon. Yue Yu was already beginning to design and deduce the runic array needed to refine this magic weapon. In addition to adding sharpness and solidification to it, the most important part is those spirit runes of the lightning system.

1. How to make it generate an electromagnetic force field. and how to hurt people with thunder and lightning. In the first half a year, Ling Yue Yu racked his brains. It wasn't until he studied with Chang Binghong for a few months that it was gradually resolved. Then it took almost a year to completely perfect it. However, what the effect is, Yue Yu himself only has a rough estimate.

"This method of carving the talisman array is somewhat similar to the way I used to carve and paint with those fruits and walnuts. I heard that this person from Yurong Peak. It is also necessary to practice condensing the spiritual sense into a knife every day, and carving various spiritual runes on iron crystals the size of rice grains. It often takes more than ten years to exercise. The only difference between the two is that when carving this rune, it is necessary to pay more attention to the changes in spiritual power. And then there's the effect on the material. I don't want to have an idea from a few years ago to lay the foundation for this refining weapon!"

When he thought about this, the auxiliary intelligence system in Yue Yu's brain had already integrated all the brain cells and started to calculate with all his might. And his analytical ability is also open to the maximum.

In fact, when it comes to the use of substantialized divine thoughts and the kung fu of the Xuan Spirit Rune, Yue Yu now doesn't know how much he is behind the disciples of Yurong Peak. Can be added to the intelligent system**. But there are two things.

After about ten minutes, the black gold was completely set. Looking at this dense rune, there is a black gold needle with a simple beauty. Yue Yu first exhaled lightly, and then his eyes gradually revealed a little expectation.

After all, it was the first magic weapon designed and refined by himself, and he naturally had great expectations for its power.

Simply inside the soul stone, he used his soul power to break into several spells, and then dripped into a drop of blood and integrated into it. Yue Yu began to urge the mana and frantically poured it into it to activate the spirit array on the black golden needle, and then stabilize the secret method.

When all these processes were completed, Yue Yu sent the black-veined golden needle that was already wrapped around his body and stabbed it into the ground. Then in a few blinks of an eye. It was like piercing the rotten wood, piercing through the spiritual array here, and traveling to a depth of more than forty miles below.

Seeing that his soul sense with this black-veined golden needle was gradually fading, Yue Yu hurriedly moved his mind and summoned it back.

As soon as I looked at this needle-shaped magic weapon that was suspended in my own "needle tip, it shone with a cold glow." Yue Yu's heart was also slightly excited

"Individually, this needle is only about the level of a six-grade needle. However, the power of the thunder magic weapon. In the cultivation realm, it has always been overestimated by one level. And because it is made of raw materials, it is made of three-grade spiritual objects. Its penetrating power is even the top-level five-grade magic weapon, and it is difficult to resist. As for the four products, it's a bit hard to say. However, when my magic weapon is completely refined, it will be enough to destroy the withering and decaying!"

Thinking of this, the impatient mood in Yue Yu's heart was even better. Seeing that the mana of his mind had recovered, he took out a part of the black-veined gold solution from the ding and continued to refine it.

In this way, for every time he refined five golden needles, he took a three-turn Yuan Pill and a three-turn Wen Ling Pill, and then meditated and rested. It took a full three days to completely refine the full set of 365 black-veined gold needles.

At this time, Yue Yu's appearance was also extremely withered, and his face was obviously extremely tired. However, in his eyes, he was mostly excited.

He first refined all the three hundred and sixty-five black-veined gold needles. Then he drove it away, and swept around the chamber like a wave. Everything in his mind is unsatisfactory, and the accuracy is much stronger than the wind-containing sword a few days ago.

"With the tide of needles gathered by these three hundred and sixty-five black-veined gold needles, I don't know how many of these four-grade defensive weapons can completely resist them?"

A strange light flashed in Yue Yu's eyes, and he scattered it again. Then when these three cars and sixty-five black needles with the thickness of the tail finger formed a circular formation. In the space inside, a thunder net was suddenly set off.

Fortunately, the refining room where he was located was large enough, and Yue Yu deliberately suppressed the power of this magic weapon, so that it did not hurt the Ran house itself.

And then, the formation changed again. This time, they formed an incomparably solid electromagnetic force field, protecting Yue Yu in it.

This was another of Yue Yu's ideas, which was able to make these three hundred and sixty-five black-veined gold needles form a magic circle, playing a role similar to that set of colorful treasure flags. It's just that because these golden needles are too thin, Yue Yu can carve the limited relationship of the spirit array, and he can only change six kinds of spirit arrays, and all of them belong to the thunder system. It's just that now, he hasn't completely finished refining, so he can't use it.

"This treasure can attack and defend, but it's similar to what I expected! Driven by this: more than 100 golden needles, the fault is not a person with strong soul power and perverted computing ability, and he must not do it. In the future, I may be the only one who can use their full effect. When I replace it in the future, I'm afraid I won't be able to sell it if I want to. Forget it, don't bother to care about him, and let's see how the power is in the last step after that!"

With a slight movement in his mind, Yue Yu began to play a few more legal decisions. Immediately after that, the three hundred and sixty-five black-veined gold needles began to converge again. When in the void in front of Yue Yu, it was completely gathered into one place. It turned out to be a combination of each other. In just a moment, in front of Yue Yu, a large sword about five feet long and two feet wide was formed.

Yue Yu stretched out his hand to hold it and waved it with his inside. Then the eyebrows were slightly raised.

"After such a combination, the structure is quite stable, and the operation of the spirit array is also unhindered! If my prediction is correct, then the grade of this black veined gold needle after the combination should be between the fourth and third grades. It's a pity that with my current cultivation. It can't be fully used yet. Over here. It's not a place to experiment with how powerful it is."

Even so, Yue Yu's heart still swelled with strong intentions. Although he had the intention at the beginning. Refining a magic weapon similar to "Wind Sword Shadow", but you can't always use the precious metal of black veined gold. It is really refined as a low-level six-grade magic weapon material,

And in the end, the workaround he came up with was just like what he was looking for. Usually it can be scattered into a black thunder rod of about six grades, and the net is his current level, and it can be fully used. In the future, after cultivating to the Jindan realm, it can also be combined into one and used as a Xuan soldier at the peak of the four grades.

First, the spirit arrays within each black-veined gold needle are different. And when they were all combined, it was a thunder spirit array of about five grades!

Immediately after that, the audition was repeated several times. Yue Yu was extremely satisfied in his heart. He ended up pulling out a small ball of silver metal ore. After smelting. All the black gold needles are coated with a silver coating. One is to protect the spirit rune on it from being replaced by Sun, and the other is to cover up its true face.

It wasn't until all this was done that the law was activated, and the current surrounding the black-veined gold needle was restricted. Placed in the Sumeru space.

At this time, Yue Yu was deep in thought. What he was thinking about now was the name of this magic weapon.
