What Yu Sheng finally chose was a two-magic circle that increased its attack power by 30% and its own solidity by 50%.

Compared to those high-level magic circles with complex strokes and extremely large spiritual elements, these two are already the entry points in the beginner's field.

A journey of a thousand miles begins with a single step, even if it is a high-rise building, it also starts from the foundation.

Seeing that Yu Sheng was not greedy, but chose these two simplest formations to learn the theory of superposition of magic formations, Wu Tiancang was greatly relieved.

This disciple understands things and knows how to advance and retreat, which is one of the necessary conditions for great achievements.

"Let's forge the sword embryo first!"

Wu Tiancang gave an order, and Yu Sheng moved in response, throwing the Xingchen Huoyun Steel into the fire outlet of the indoor Dari Rulai True Fire, and burned it with fierce fire.

This thing originally came from the lair of the six-grade demon beast Fire Phoenix, and after Lao Bai's purification, the not too big piece of Huoyun Steel left behind now happens to be the spiritual material of the Sex Flame Flame.

Spiritual weapons are divided into different attributes, which are naturally determined according to their own spiritual materials.

If it is a water-based spiritual material, the method of forging a spiritual weapon does not rely on this fierce fire, but uses yin fire to slowly refine it into shape. However, this kind of fire-based Xingchen Huoyun Steel is very suitable for forging under fierce fire.

Yu Sheng opened the fire door in the room to the maximum, and the real fire of the great sun in the underground was all triggered, and jumped up, the room temperature suddenly rose by more than ten degrees, and the fire cloud steel was burned all over the body, and the original red color was even brighter and dazzling at the moment.

It didn't take too long, Yu Sheng had already seen that Huoyun Steel was faintly showing signs of softening.

What a great flame!

If it is really the power of the power of the Buddha's power 10,000 years ago, after 10,000 years, there is still such a surging fire, then this person's cultivation is ...... I can't imagine it!

In comparison, Lan Dun, who flaunted his might in the Duobao Sect, was nothing!

For a while, Yu Sheng's heart was full of pride, and he no longer took the strong man who broke the mountain in his heart with one palm. A few steps forward, while the Huoyun Steel softened, he picked up a diamond hammer of the best quality provided by the Ponzi Firm, and began to forge with strength.

There is a very strange requirement for forging metal spiritual materials......

You can't use the spirit element as a monk!

Many monks have reached the high ranks, and they have the power to move mountains and reclaim the sea with their own gestures, but when it comes to their own strength, they may be very weak.

This requirement has caused many people to lose their relationship with the Refining Sect Master forever.

Not every cultivator has the power to wield a hammer, and many people are just a weak person who walks and shakes after giving up the spirit element.

The reason why there is such a strange request is because the spiritual material is still being forged, and if it is infiltrated by the monk's spiritual element, it is likely to change its original characteristics, making the subsequent spirit array carving extremely difficult.

Even some spirit elements were deeply imprinted in the depths of the spirit materials during the forging process, making the formation completely useless under this interference.

Wu Tiancang was still very worried at first, although Yu Sheng was twenty years old this year, just when he was young and strong, his strength was not too bad. But if you are an ordinary and polite reader, with the strength of your two arms, you can catch a chicken and a dog, which is not bad.

But after Yu Sheng heard the request not to use the spirit element, he laughed mysteriously.

With a hammer in the next stroke, Wu Tiancang's eyes glared out.

This Nima ...... O born refining master!

He didn't know that before Yu Sheng came to the spirit world, he had a well-known title in Chang'an City-the son of the leader of the martial arts alliance.

Although he is only fifteen or sixteen years old, he has already had a fire foundation of more than ten years.

Although I have been in the spirit world for five years and wasted my cultivation, after all, the foundation is too good, what is the matter with a hammer!

Yu Sheng himself was very happy, and the sound of clanging was endless, as if he had inexhaustible strength.

It's been five years! I haven't had the opportunity to use the internal strength of this penance since childhood, but it's like meeting an old friend who has been separated for many years.

Wu Tiancang said darkly: Could it be that the innate divine power is a bit similar to the demon cultivation that mainly forges the body, no wonder it is so close to the spirit beast, is there any blood connection? Then this kid has to be called...... Shemale ......

Under such a huge forging force, the Xingchen Fire Cloud Steel gradually took shape, and a red spirit sword revealed a more and more perfect body on the chopping board.

Not bad!

Wu Tiancang smiled, originally thought that although the material of this sword was not bad, it was only two low-level magic circles, and at best it could reach the level of the green spirit weapon, but with this kind of huge forging against the sky, I was afraid that it could barely achieve the green spirit weapon, and maybe it would be!

If there is a lot of time, Wu Tiancang will naturally be able to slowly hone Yu Sheng's refining skills, then with this Star Fire Cloud Steel, refining the Blue Spirit Weapon may not be impossible, but now...... There's no time for that!

The experienced Wu Tiancang immediately thought that his apprentice might be lackluster in alchemy, and even if he had his own teachings, his achievements would inevitably be limited.

But this refiner ...... With the foundation of this hand hammer, that is the expected grandmaster!

"The sword embryo is almost done, start to carve the magic circle, first draw the reinforcement formation!"

Wu Tiancang controlled the overall progress and reminded him at the right time.

Yu Sheng nodded silently, grabbed the special spirit array carving knife that had been prepared a long time ago, and began to sketch and depict it stroke by stroke on the red-hot sword embryo.

He had long been familiar with this magic circle, and he had tried to carve it countless times on the ground, on paper, and on small pieces of spiritual materials.

Coupled with the fact that the eldest young master has always had a calm mentality, although it is the first time that he has officially depicted the sword embryo that is about to take shape, there is no trembling, and the pen is in place.

Perfectly done!

The circle had successfully finished drawing the last stroke, and the entire sword embryo let out a low chirp, and a faint glimmer of light flashed inside, enveloping the patterns just now. When the light dimmed, the strokes seemed to be deeply embedded in the sword embryo, naturally generated. Between the turns of the pen, there is a faint sense of profoundness.

Then came the most difficult step, the circle stacked.

"Do you remember the strokes of that attack bonus formation?"

Wu Tiancang pointed to the sword embryo and said solemnly: "Look at this magic circle that has been drawn!"

"Your second circle, all the strokes, must not only follow their own rhythm, but also calculate their positions. The rule of thumb is that it is best not to intersect with the strokes of the existing circle, and if there is, then the following strokes must coincide until the end of this one. ”

"Moreover, if you can't choose another blank space to re-depict, that is not the true meaning of the superposition of the Spirit Array, and it will not have the effect of increasing attack and increasing solidity at the same time. ”

So that's it......

Yu Sheng frowned, looked at the sword embryo in front of him fixedly, and thought hard about how to arrange strokes on the existing magic circle to meet these requirements put forward by Teacher Cang.

It's not a simple matter.

Even if Yu Sheng has a flexible brain, he has been thinking hard for several hours, constantly deducing the possible stroke direction in his mind.

By the time he officially started, the sword embryo of the Star Fire Cloud Steel had completely cooled down, which was more convenient for him to put down the pen of the Spirit Array Carving Knife.

This time, he was extremely slow, because not only did he have to perfectly realize the direction of the new circle, but he also had to pay special attention to cooperating with the old circle, and he couldn't do whatever he wanted.

In the sea of knowledge, Wu Tiancang's divine sense probed out, observed for a while, and smiled with satisfaction again.

Although the progress is not fast, it is still stable and calm, and according to this development, it is no longer difficult for this disciple to be superimposed by the double array.

Sure enough, two hours passed, and Yu Sheng's last stroke was finished.

The sword embryo let out a low groan again, this time the faint light of the two magic circles lit up at the same time, one pale red, the other was gray and black, the light interlaced in the air, and gradually merged, forming a unique color of black and red.

Soon, the sword embryo calmed down, and the two magic circles had been condensed in it, perfectly cooperating, without the slightest conflict and interference.

"Well done!"

Wu Tiancang only then expressed his appreciation, he was able to truly portray the spiritual weapon array for the first time, and he was a great success, which shows that his inference is not bad, this kid's talent for refining weapons can be regarded as excellent.

At this point, there is only one last step left in the forging of the spirit sword, quenching the sword embryo of the carved magic circle again, but no longer forging it, but using the most violent flames to completely condense the power of the spirit material itself and the ability of the magic circle in one place, forming an unbreakable whole.

This step, but basically does not require human involvement, only need to control the flame to the maximum, the more fierce the flame, as long as the spiritual material can withstand it, the more it will help to improve the grade.

Often, many spiritual weapons that are about to take shape are not perfectly fused because of the limited power of the final flame, and they are defeated by small grades, from high-level spiritual weapons to medium-level or even lower.

The big day is really hot, and it will not disappoint Yu Sheng.

This burn will be another two or three hours.

Forging spiritual weapons is really time-consuming......

Yu Sheng had carved the spirit array for a long time, and he was able to breathe at this moment, looking at the somewhat illusory and unreal spirit sword in the flames, and slowly recovering his tired spirit.

Although this material is something or something, but after all, I have worked hard, but I have eliminated most of my bad feelings, and I began to look forward to it.

What kind of spiritual weapon will it be?

Yu Sheng's eyes were shining, staring at the spirit sword that was about to complete the entire forging process.

As long as the light is on, it will be announced that it is done, and at the same time, the level of the spirit weapon will also be clear at a glance.

After a while, all of a sudden, the green light was flourishing!

After all, is it just a green spirit weapon?

Yu Sheng was slightly disappointed, if this was the case, even if it was a high-level green spirit weapon, he was a little sorry for the material of Xingchen Huoyun Steel.

It seems that his refining technique, even with Wu Tiancang's hand-in-hand guidance, is still quite lacking.

But the green light became more and more abundant, and finally flashed out, and in its place, it was a faint, but more touching touch of pale cyan.

Green Spirit Weapon!

Yu Sheng was a little happy at this time, it was quite rare for the first time to refine the weapon at this level, and the progress of the green spirit weapon compared to the green spirit weapon was not a little bit.

"Not bad!"

Wu Tiancang also nodded and smiled: "Don't look at this as a low-level green spirit weapon, but whether it is the material or the core magic array, it is meticulous, compared to your unscrupulous and impure unrefined technique, it is much better!"
