This is a kind of copper material for refining fire spirit weapons, and this fire copper ingot was naturally not refined by Yuwen Zhouyuan himself, but was taken from Sun Zhenjie after killing him.

Yuwen Zhouyuan concentrated, and a black and white flame the size of a thumb appeared above his palm, although this flame appeared, but the strange thing was that there was no scorching heat around him.

This black and white true fire is the unique innate true fire of Yuwen Zhouyuan, this special innate true fire is also called the true fire of the yin, the black flame of the yin fire, is the mutated true fire of the fusion of the yang and the yin, this fire was blue and white at the beginning, and with the increase of cultivation, it became black and white.

This kind of true fire can only be cultivated by those who have cultivated the Zhi Yin Gong Method!

It's not right, if you look closely, you will find that the temperature on the left side of Yuwen Zhouyuan's body seems to be very high, but he can't feel how hot it is, but a futon within three feet of his left side will automatically burn up almost instantly and turn into ashes!

And a pot of orchids placed three feet on the right side of Yuwen Zhouyuan is full of ice!

Seeing the changes around him, Yuwen Zhouyuan hurriedly took out the array plate and array flag and threw it out, and immediately the entire room was protected by the array disk and array flag.

At this time, Yuwen Zhouyuan let out a sigh of relief, and secretly said that he had been really careless recently, refining the magic weapon and not releasing the protective array, this was the lowest mistake, where was the original caution?

It seems that after joining the sect, his dependence has increased, but his vigilance has decreased, which is definitely not a good thing for himself! It seems that he has to remind himself all the time that he must be cautious at all times, and be careful not to make a big mistake!

Yuwen Zhouyuan controlled the copper ingot with one hand and threw it into the flames.

As soon as the ingot came into contact with the flames, it was gradually melted into a mass of metallic liquid by the high temperature, which slowly rotated.

After a full meal, it gradually turned into copper liquid because it could not withstand the flames of the Innate Yin True Fire, and it boiled and burned.

Most of the palm-sized fire copper ingots were burned away by the Innate to Yin True Fire again, leaving only a very small amount of fire copper essence.

Some liquid fire copper essence then formed a fire copper essence block under the extreme cold of the innate to yin true fire.

Then Yuwen Zhouyuan put the fire copper essence block aside, and he let out a breath, looking at the fire copper essence block, while thinking about how to refine the weapon in the next step.

Because Yuwen Zhouyuan's innate to yin true fire is different from a plate of people's innate true fire, ordinary people's innate true fire only has heat, but no coldness, which is much easier than refining weapons.

If Yuwen Zhouyuan's innate to yin true fire is half extremely hot and half extremely cold, if it is not well controlled, the refining materials will be wasted, but if it can be controlled well, the grade of the magic weapon will be higher after refining the cold and heat!

Yuwen Zhouyuan released his divine thoughts to check it, and found that this fire copper essence was already very pure, and he could no longer remove any dregs from the fire copper essence, Yuwen Zhouyuan took out the second fire copper ingot and threw it into the flames.

Dozens of fire copper ingots were continuously invested, all of which were converted into high-purity fire copper essence.

Seeing that it was almost enough, Yuwen Zhou Yuan quickly pinched the refining weapon in his hand, mixed these liquid earth fire copper essences together, let them float in mid-air, and hit several magic decisions in a row, melting them into a small sword rudiment.

Then he mobilized the cold attribute in the flame with his divine thoughts, and shaped it on the small sword little by little, only to see that the small sword liquid trembled in the flames, gradually taking shape.

Time passed little by little, and fine beads of sweat appeared on Yuwen Zhouyuan's face, but he didn't dare to relax at all, now he was still far from the completion of the short sword, and now it was only a rough embryo of a short sword at most.

After the half-pillar incense work, the short sword was basically formed, and the whole body was blooming with golden copper light, at this time, the short sword can already be regarded as a fire copper spirit sword, and it can be worth a lot of spirit stones when it is sold.

However, Yuwen Zhouyuan did not stop, with a finger of his right hand, an extremely faint sword qi burst out from the tip of his finger and shot towards the sword body.

The sword qi burned a miniature formation on both sides of the sword body of the fire copper sword at an extremely fast speed.

This kind of sword body formation is usually not very powerful, and can only play an auxiliary role. For example, place a wind light spirit formation to reduce the weight of the sword body. Or a fire-based formation, when using the Spirit Sword Land, you can automatically release a variety of low-level fire-based spells to attack the enemy, and so on.

On the hilt of the sword, there is a slot left where spirit stones can be placed, which can be used to stimulate the effect of the sword body formation.

An hour later, a high-grade fire bronze spirit sword with a simple shape that could be held in the palm of his hand was finally completed.

Yuwen Zhouyuan wiped his sweat and played with the fire copper sword in his hand with satisfaction. After self-learning the refining weapons of the Butcher Demon Lord and Qiu Hongwei, he successfully refined a high-level spiritual weapon in his first trial!

It seems that if you want to refine the magic weapon, as long as you are familiar with your own special innate supreme yin true fire, it is possible to succeed! Yuwen Zhouyuan secretly said in his heart.

Fire copper is the easiest material to refine, which is why he used fire copper to refine his hands first, Yuwen Zhouyuan plans to refine the armor for Nangong Dai after refining a magic weapon again, so the certainty of success is also higher.

Yuwen Zhouyuan suppressed the excitement in his heart, and then crossed his knees and carefully recalled how to control his innate Yin True Fire, which was very different from ordinary people.

Unconsciously, the sky was bright, and after a night of pranayama, Yuwen Zhouyuan had greatly improved both his theoretical knowledge of refining weapons and his ability to control his Yin True Fire.

After opening his eyes and letting out a long breath, Yuwen Zhouyuan seemed to think of something again, only to see him take out a small bag from the storage bag and pour out all the things inside, it turned out that these were all kinds of spirit grass and some miscellaneous things that he had purchased from the stall in the market.

Yuwen Zhouyuan sorted out these spirit grasses, then held them in his hands and closed his eyes to investigate, and soon he settled down, and then his divine thoughts entered the mysterious space in the "Book of Heaven".

As soon as he entered, Yuwen Zhouyuan found that the area here seemed to be a little larger than before, the aura was still as rich as ever, and the spirit grass, spirit flowers, and elixirs in the medicine garden exuded a rich aroma.

Yuwen Zhouyuan came to the medicine garden, planted those spirit grass elixirs, and then looked at the other spirit grasses and elixirs in the garden and found that those spirit grass elixirs had all been completed, even those ginseng and other things with the year as the medicinal property, and they had also reached the age of at least three thousand years, and it would not take long to see that the elixirs of 10,000 years or even 100,000 years would appear!

If there is a 100,000-year-old elixir, then its value will be immeasurable! Looking at this medicine garden, Yuwen Zhouyuan's eyes were full of longing.

Yuwen Zhouyuan walked out of the medicine garden, looked at those spirit stones, and found that at this time, those low-grade spirit stones were no longer low-grade, and there was already a faint transition to the middle grade, and the top-grade spirit stones also began to transition to the top-grade spirit stones!

The most amazing thing is that those top-grade spirit stones actually began to change color, and the spiritual power emitted on them was no longer simple spiritual power, but there was a faint immortal aura.

The ground around the top-grade spirit stone had completely turned into a whole low-grade spirit stone at this time!

Yuwen Zhouyuan looked at a few small stones on the side of the mid-grade spirit stone, and found that the ordinary stone he put there last time had completely turned into a good-grade low-grade spirit stone!

What's even better is that these spirit stones are actually the same attributes as the original spirit stones closest to it!

This space is too mysterious, it's just that it's not very convenient to enter and exit, and it would be better if you could enter and exit at will!" Yuwen Zhouyuan thought.

Yuwen Zhouyuan picked some mature elixir and prepared to leave this space.

Suddenly, he saw the seven-colored glass tripod at a glance, so he stopped again.

Yuwen Zhouyuan suddenly thought of the "Tianding Mantra" that appeared on this seven-color tripod last time.

It seems that the "Tianding Mantra" is the method of manipulation of this seven-colored glazed tripod, and he is idle now, why not try to practice.

Thinking of this, Yuwen Zhouyuan sat down cross-legged, and then took out the "Tianding Mantra" copied on the jade slip and began to comprehend.

As Yuwen Zhouyuan kept reciting the mantra in his mouth, the seven-colored glazed tripod actually emitted a colorful light outward.

Because Yuwen Zhouyuan was engrossed in reciting the "Tianding Mantra", he didn't notice the change in the seven-color tripod.

As the colorful light continued to emanate, the solemn color on Yuwen Zhouyuan's face became more and more solemn, and he read more and more slowly......

Suddenly, the colorful glazed tripod flew up violently, Yuwen Zhouyuan seemed to sense the difference, he opened his eyes, and saw the colorful glazed tripod that flew into the air, Yuwen Zhouyuan's mind suddenly appeared in the "colorful sky, the mind is moving, not dirty and not sick, I use the mantra!"

Although he didn't know the reason, Yuwen Zhouyuan instinctively increased the recitation of the "Tianding Mantra".

As the "Tianding Mantra" kept reading, Yuwen Juyuan felt that his mind was ethereal, as if nothing existed, and his thoughts were left in this world to wander in the endless universe.

Yuwen Zhouyuan didn't know that the state he had entered at this time was the realm of "no dirt and no disease", but he didn't expect him to break through to this realm by mistake.

As Yuwen Zhouyuan entered the realm of "no dirt and no disease", the mouth of the colorful glazed tripod in the air actually began to produce a suction, and I saw that the rich spiritual power of the entire space kept surging towards the tripod.

With the influx of spiritual power, the brilliance of the colorful glazed tripod was magnificent, and then bursts of dragon-like voices came from the tripod, and then the phantom of a dragon appeared at the mouth of the tripod.

The dragon is colorful, constantly rolling in the mouth, the mouth swallows clouds and mist, with the appearance of the colorful dragon shadow, the colorful glazed tripod actually exudes bursts of medicinal fragrance......

I don't know how long it took, it seemed to be a year, two years, ten years, or even a hundred years, and it seemed to be just a moment, Yuwen Zhouyuan's brain shook violently, and he returned to reality!

As Yuwen Zhouyuan's divine thoughts returned to reality, the colorful dragon shadow above the colorful glazed tripod then disappeared, but the strong medicinal fragrance was still there!

After the colorful glass tripod lit up violently, it slowly fell to the ground again.

Yuwen Zhouyuan suddenly felt a sense of mental tiredness coming, he slowly stood up, and then walked towards the colorful glass tripod.
