"At the moment when the ultimate divine material casts the Dao weapon, it can be refined with the essence of the divine artifact containing fire, or it may be able to achieve the forbidden artifact......"

This is contained in the Taoist Instrument Sutra, which means that the Dao Weapon is cast with the ultimate divine material, and at the moment of initial completion, it is refined with the essence of the divine object that gives birth to the fire of the Dao Weapon, and this Dao Weapon may hopefully grow into a legendary forbidden artifact in the future.

This account is one of the few places in the Taoist Instrument Sutra where the forbidden artifact is mentioned.

Moreover, at the end of the record, even the author of this Taoist Instrument Sutra explained that this is only a legendary hypothesis, and in the heavens and all worlds, for endless years, there is no definite record, and the forbidden artifact can be obtained by this method.

All because the conditions are too harsh, the ultimate divine material is rare to see in the ages, and the people who use it to forge Dao weapons are very few even among the heavens and ten thousand worlds.

And even if there is the ultimate divine material, when casting the Dao weapon, the fire used is generally from the earth fire, the fire Dao magic weapon, or the fire evolved from the fire divine skill.

But what is needed here is a divine artifact, and only a Dao weapon refined from the fire generated by a divine artifact can be refined using the essence contained in this divine artifact, so that this Dao weapon can achieve a forbidden artifact in the future.

In addition to being too harsh, this condition is also a bit nonsensical, and if you refine it, why can you only use a divine object that contains the fire of refining Dao weapons?

For countless years, there may be people in the heavens and all worlds who have known about this method, but they basically laughed at it, this condition is not in line with the common sense of cultivation at all, and it is more like a person who doesn't understand anything, talking nonsense for the sake of grandstanding.

In addition, even if the forbidden artifact can be achieved, it needs the master of the Dao weapon to achieve the forbidden position first, and then its Dao weapon can be turned into a forbidden artifact, but how many people in this world have achieved the forbidden position?

And the forbidden artifact is only a legendary thing, involving the word taboo, no one can say, whether there is such a treasure in this world, it is not certain.

Therefore, even the person who compiled this Taoist Sutra is not sure that the reason why it is recorded is only to narrate an ancient legend.

Xu Zifan naturally didn't believe it much, but he might just meet these harsh conditions, of course he had to try, even if he didn't succeed, he would have no regrets in his heart.

As for why it is possible to meet these demanding conditions?

The main reason is that there is not much fire energy that Xu Zifan can access now.

Most likely, it was born from a divine object, and only the fiery energy of this place was born.

Because Xu Zifan speculated that the gray mist here was the chaotic mist, and the magma sea and Kunlun Mountain on both sides of the gray haze, and even the entire Xiaoao Jianghu world, were all evolved from the chaotic mist, and the chaos mist, needless to say, must be a super divine object.

This is just his speculation, so he may fit these demanding conditions.

Therefore, in order to have no regrets in his heart in the future, Xu Zifan doesn't mind trying it under this condition, and this is the main reason why he refines Dao weapons in this world, otherwise he can also find earth fire in the Zhuxian world, the aura is even stronger, and there is a ten-to-one time benefit, wouldn't it be better?

"Brush!"

Xu Zifan's figure shot straight out, heading towards the road he came from at full speed, and in this process, above his head, the Xuanying Mirror always followed, and the blue sky in the mirror was vast, falling down the vast blue light, protecting his body up and down.

In just half an hour, he had returned to the southwest of this world, at the end of the world.

Looking up, I saw a gray mist sweeping through the sky ahead, dividing the whole world into two heavens, ice and fire, which is like the birthplace of mythology, which is extremely shocking and makes people feel insignificant.

Moreover, looking closely, in the vast gray mist, there were traces of purple electric flashes from time to time.

These occasional purple electric lights, although only as small as a hair, are more mysterious, but whenever they appear, they all give people a sense of fear and awe.

At this moment, Xu Zifan was still thirty miles away from the gray mist in front of him, but he had a feeling of palpitations, and his body was trembling instinctively, as if there was great danger there.

It's just that you need to refine the Dao device, this distance is obviously not good, and how to refine it? Do you throw the Mirror directly into the gray mist ahead?

Obviously impossible, even if the Xuanying Mirror was refined by the ultimate divine material, Xu Zifan still didn't dare to take risks.

If the gray mist in front of him was really the legendary chaotic mist, then even if the material of the Xuanming Mirror could resist it, the spiritual consciousness and artifact runes he left in the Xuanying Mirror could not resist it.

Therefore, if you want to refine the Xuanyin Mirror, you need to think of another way.

Looking at the vast gray mist in front of him like a sea of chaos, falling from the sky and surging, Xu Zifan first thought about it, and then his eyes lit up.

You can't throw the Mirror into the gray mist, but you can try to introduce a trace of gray mist into the mirror.

Thinking of this, Xu Zifan no longer hesitated and immediately started to act.

He endured the palpitations in his heart and began to move forward slowly, at the same time, he felt a terrifying force as if it was about to crush him to pieces, but the next moment, this pressure suddenly disappeared, replaced by a tearing force from all directions, this extreme contrast made Xu Zifan have the urge to vomit blood.

Step by step, Xu Zifan continued to move forward, and in the process, he felt all kinds of chaotic forces, sometimes tearing, sometimes oppressing, sometimes hot, sometimes cold......

It's just a short distance, he seems to have experienced a thousand catastrophes, and at a certain moment, Xu Zifan's proud body was also cracked, and blood slowly oozing out, dyeing him into a bloody man.

By this time, he was still twenty miles away from the vast gray haze ahead.

"That's it!"

Because of the terrifying and inexplicable chaotic power, Xu Zifan's face was a little distorted because of this, but at this moment, a smile appeared on his face, and when he walked here, he could start refining the Dao weapon.

"Go!"

Xu Zifan drank lightly in his mouth, stretched out his hand and pointed at the Xuanying Mirror suspended above his head, and suddenly the blue light shone, turning into a blue and black divine light towards the gray mist in front of him.

The speed of the Xuanming Mirror was very fast, like a long rainbow passing through the sky, and almost in the blink of an eye, it had already come to the vast gray mist.

It's just that when the Xuanming Mirror arrived here, Xu Zifan's face instantly turned pale, and then he slowly recovered.
