The first step is to melt the molten iron, which is mixed with ingredients such as gold and silver.

The molten iron is then poured into the mold and made to become the blank of spears and knives.

The next step is to place these blanks on the anvil, and let the disciples of the Green Dragon Clan and the White Tiger Clan hold the hammer and forge it repeatedly.

The disciples of the Blue Dragon Clan and the White Tiger Clan have been suffocated these days, and they have nothing to do, so they can show their skills today.

Repeatedly heated, repeatedly forged, and then tempered by the disciples of the Xuanwu clan, the four heavy weapons have been basically formed.

Finally, it was time to grind, and the demons found the hardest stone in the mountain and sharpened the four weapons very sharply.

In addition to refining weapons, Yi Jiuxiao also taught the demon martial arts skills and various exercises.

These disciples involved in refining weapons are all core disciples of the various True Spirit Families, and after they master it, they can pass it on to other disciples.

Next, more demon clan disciples joined the refining weapon, from the initial twenty to the current more than fifty.

These later disciples brought some refining materials, which are not lacking at all at present.

The Yantian Continent has not had a refining weapon for tens of thousands of years, and there are many natural materials of all kinds.

In addition to searching for natural materials, the six true spirits all mobilized their affiliated families to excavate materials and use refining materials as their annual tribute.

Because of the increase in the number of people, Yi Jiuxiao asked the demons to open another earth fire vent and redo a furnace.

In addition, an anvil and tools such as hammers, drills, and hooks were made.

Because the two ancestors of the True Phoenix Clan are the highest in cultivation, and they are in the territory of the True Phoenix Clan, they serve as the leaders of the craters on both sides.

Nizi is in charge of managing these demon clan disciples, and the Heaven Swallowing God Clan has the most experience and talent in managing the demon clan.

Yi Jiuxiao led the demons to continue refining heavy weapons for a year, refining a total of hundreds of various weapons.

These weapons were all distributed to the various True Spirit Families for those disciples to practice their combat skills.

With a year's experience in heavy weapon refining, Yi Jiuxiao and the demons have basically mastered heavy weapon refining.

Yi Jiuxiao decided to start refining immortal weapons, and with the increase in the cultivation of some disciples of the demon clan, heavy weapons were no longer suitable.

After three months of repeated attempts, Yi Jiuxiao finally refined the first immortal long sword.

This immortal weapon is very rough, but it is indeed an immortal weapon, and after the successful refining, it gave the demons a lot of confidence.

Yi Jiuxiao was able to quickly master the refining of immortal weapons, thanks to the fact that he saw the four Great Elders refining artifacts with his own eyes on the Island of No Return.

Although he didn't do it himself at that time, he saw all the entire refining process, and the four Great Elders also explained it to him.

So now he has made immortal weapons with his own hands, and he has taken a lot of detours, and the progress is also very fast.

In the next two months, under the guidance of Yi Jiuxiao, each furnace was refined to produce an immortal weapon.

With a good start, the process of familiarization followed, and Yi Jiuxiao decided to let the demons refine it on their own.

Most of the contents of the Martial Arts Instrument Sutra have been carved into jade slips and distributed to the demons, and if you don't understand it, you can refer to the Martial Arts Instrument Sutra.

He himself wanted to go to the crater of the True Phoenix Clan to refine his body, and the extremely high temperature there was very good for refining his body.

At this stage, Yi Jiuxiao has to focus on improving his cultivation, and his initial cultivation of the Martial God is still too low.

After settling the matter of the refining point to Nizi, he flew towards the crater of the True Phoenix Clan.

Feng Qiwu, the patriarch of the True Phoenix Clan, had said before that Yi Jiuxiao could come over to cultivate at any time, and there was no need to tell him.

He didn't dare to fly to the deepest part of the volcano in one go, where the temperature was too high.

Even the disciples of the True Phoenix Clan didn't dare to cultivate in the deepest depths, and Yi Jiuxiao couldn't do it.

Twenty miles away from the crater, Yi Jiuxiao felt that the heat was unbearable.

At this time, the surroundings were all red, even the sky was reflected red, and he seemed to be in a melting pot.

So he stopped in the air and cultivated the dredging palm to dissipate the heat on his body.

After practicing the Dredging Palm a few times, he slowly began to get used to it, and it was not as painful as before.

Suddenly, Yi Jiuxiao remembered the Red Flame Arrow, and wondered if the Red Flame Arrow could absorb the heat here and grow.

When he was in Wushan Chaoyun Peak, the Cold Arrow had absorbed the extreme cold in the sky, and finally synthesized a large arrow.

Thinking of this, he took out ten Red Flame Arrows from the chaotic space.

The moment I started it, I felt a hint of coolness around me, and the temperature was no longer so high.

It seems that the heat around it is absorbed by the Red Flame Arrow, and his own approach can work.

Yi Jiuxiao didn't stay any longer, since the temperature here was not enough, staying here would be of no use.

He walked forward with ten red flame arrows until he came to a halt fifteen miles from the center of the volcano.

The temperature here was more than twice as high as the previous position, but with the Red Flame Arrow absorbing heat, Yi Jiuxiao could bear it.

After placing the ten Red Flame Arrows around, he landed on the ground and began to cultivate.

first cultivated the Open Heaven Fist, and then cultivated the Dredging Palm.

During the cultivation, the surrounding heat was transformed into the power of qi and blood by the dredging palm, and flowed into the chaotic space.

The Divine Spirit Turtle that covers the heavens here has already reported the information, saying that it is unbearable.

Yi Jiuxiao turned the Heaven Covering Armor into a belt, and he completely relied on his physical body to fight against the extreme heat.

A year passed, and Yi Jiuxiao traveled five miles to the center of the volcano after repeated body refining.

At this time, his cultivation was completely stabilized in the early stage of the Martial God, and his strength and speed were even stronger than when he had just advanced.

The second year passed, and Yi Jiuxiao's location at this time was only a thousand zhang away from the location of the crater.

He could clearly see the crimson magma rolling like a tidal wave, and white flames flying happily under his feet.

How hot is it here, Yi Jiuxiao tried to take out a piece of fine iron from the chaotic space and threw it forward.

The fine iron melts rapidly at a speed visible to the naked eye, then turns into ash and disappears.

He was dumbfounded with fright, no wonder Feng Qiwu said that the crater here was not suitable for refining weapons, and those materials would be gone if they were put in.

Ten Red Flame Arrows didn't matter, it seemed that the baby had returned to its mother's arms, sucking milk.

Because the Red Flame Arrow had already dripped blood to recognize the Lord, Yi Jiuxiao was connected to his mind, and he felt the joy of the Red Flame Arrow in his divine thoughts.

When cultivating, Yi Jiuxiao had some whims, and suddenly thought that he could also become a true phoenix.

So it was transformed into a golden true phoenix that has always been brilliant.

In the moment of transformation, he felt the heat around him suddenly decrease, and he almost didn't feel uncomfortable anymore.

Taking it a step further, he spread his wings and flew towards the center of the crater, feeling the heat change.

Ten Red Flame Arrows were driven by his mind, accompanied him like a shadow, always wrapped around him.

Yi Jiuxiao was completely placed on the flames of the crater, and the pure white flames kept hugging him.

He didn't dare to get too close, and this hug, although cheerful, was a fatal temptation.

Although he had turned into a true phoenix, Yi Jiuxiao still had the fear that he would be engulfed in flames and turned into ashes at any time.

The beautiful flames in front of you are so hot that you don't even feel pain.

He didn't dare to take it lightly, so he practiced the dredging palm with the body of a true phoenix.

Doing so is not only competing with the heat, but also absorbing the heat.

At this time, his body was a piece of material, which was repeatedly tempered in this melting pot of heaven and earth, and tempered into artifacts and holy weapons.

At the same time, he urged ten red flame arrows with his mind, allowing them to slowly probe into the white flames.

Just after the Red Flame Arrow came into contact with the White Flame, the White Flame disappeared, and it seemed that the Red Flame Arrow could eat the White Flame.

Great! Since the Red Flame Arrow can eat the White Flame, let's let it eat enough at once.

Yi Jiuxiao used the body of the true phoenix to cultivate the dredging palm, and at the same time urged the red flame arrow to devour the white flame.

If he felt tired, he hid in his chaotic space, ate and drank a lot, and rested.

Time is passing bit by bit, and nine months have passed in the blink of an eye.

On this day, the Red Flame Arrow suddenly stopped eating the White Flame and seemed to have eaten enough.

Yi Jiuxiao knew that it was time, and when the cold arrows were saturated with cold qi, they were synthesized together.

So he used his mind to bring the ten red flame arrows closer to each other, and the moment they touched each other, they really merged into one big arrow.

After synthesizing, a single Red Flame Arrow began to eat White Flame again, and it ate more ferociously, and it was a large piece as soon as it was eaten.

After letting the synthesized Red Flame Arrow eat the White Flame for three months, Yi Jiuxiao felt that it was time to go out.

He had been cultivating for three years since he entered the True Phoenix Clan's volcano, and he didn't know what was going on outside, so he should go and take a look.

It may be that the Red Flame Arrow can absorb the flames and grow, but it will not happen overnight.

At this time, his own cultivation has also improved greatly, and he is slowly approaching the middle stage of the Martial God, but it will take time.

After flying thousands of miles, when he came to the location of the refining weapon, he saw that there were more than a hundred true spirit disciples of various races who were refining the weapon in full swing.

In the past three years, they have refined dozens of immortal weapons, and there are countless heavy weapons.

Yi Jiuxiao gathered everyone together and first asked about his experience in martial arts cultivation.

The two ancestors of the True Phoenix Clan had advanced to the early stage of Martial Immortals at this time, and Peng Wei had also advanced to the middle stage of Martial Emperor cultivation.

Yuan San actually joined the ranks of refining weapons, and several half-true spirit families such as the White Phoenix Clan also had disciples among them.

When the refining table was set up, it was originally for the six true spirit families to refine weapons, and the materials were also provided by the six true spirit families.

Later, the patriarchs of those half-true spirit families came in person and were willing to provide materials to participate in refining weapons and martial arts cultivation.

So Nizi agreed, because martial arts will spread throughout the Yantian Continent in the future, and martial arts refining weapons must also be learned by more families.

Yi Jiuxiao naturally has no opinion on this, as long as everyone can get along with each other.

However, with Nizi, a person from the Heaven Devouring God Clan, in charge, those demon clans are also obedient.

After all, the Heaven Swallowing God Clan has ruled the Yantian Continent for tens of thousands of years, and obeying and worshiping the Heaven Swallowing God Clan has penetrated into the soul of the Demon Clan.
