After listening to Qingfeng's explanation, Fang Lie not only didn't understand, but became even more confused.

What kind of place is Xuanmen? Don't look at the scarcity of people, but it can definitely be called the first sect in the world, not only is it the strongest in the world in alchemy, but its own strength and financial resources are also the best in the world.

Moreover, from ancient times to the present, people have done countless businesses, and they have seen all kinds of treasures, but they have never broken the rules.

But this time, although their approach is not a reckless, it is also a bit unkind. To even pay for the purchase of treasures ordered by guests, where is this the magnanimity that a large sect should have? It is so inappropriate, and it is a little embarrassing to say it.

With the arrogance of the Xuanmen, if something particularly strange hadn't happened, even if they were killed, they wouldn't have done such a tasteless thing.

The other one was that the other party's offer scared Fang Lie. Normally, the power of a large treasure at the peak of the eighth order is sometimes comparable to that of the lowest ninth order lower grade magic weapon, but when it comes to fighting, it is actually slightly inferior.

Because the power of the large treasure is piled up with a large number of materials, thousands of times more materials than ordinary magic weapons, the power exerted is naturally much greater, but it also loses its flexibility.

Especially in the ninth order, the magic weapon has a tool spirit, and the wisdom is no less than that of the old monsters, and with their assistance, the power of the magic weapon can be exerted to the extreme.

But large Noble Phantasms are different, and their bulky size and urging methods make them particularly cumbersome.

It is used to attack something that cannot be dodged such as the mountain protection array, and that's it, the power is fully opened, not much worse than the ninth-order magic weapon.

However, if people fight, large treasures will often fail to beat people, and at this time, their combat power is far lower than that of ninth-order magic weapons with machine spirits.

In addition, the rarity of the two sides is also very different. The eighth-order large treasure phantasm, as long as the materials are sufficient, can be refined, although it is laborious, it is not particularly rare.

But the ninth-order magic weapon is different, if you want to obtain it, it is even more difficult, even if it is a large sect like Momen, which has been inherited for hundreds of thousands of years and is famous for refining weapons, there are not many at all.

In contrast, the number of eighth-order large treasures is ten times or twenty times more, such a large difference in quantity, coupled with the difference in practicality, leads to a huge difference in the status of the two.

If it really comes to terms of value, the ninth-order magic weapon is still much higher than the large-scale treasure at the peak of the eighth order.

But this time, the other party not only gave a ninth-order magic weapon, but also a medium-grade one. Don't look at the difference between low-grade and medium-grade products, but in terms of value, the gap has been at least five to ten times.

In particular, the Black Steel Mountain Seal is the main force of the Xuanmen Conquest Quartet, with a far-reaching reputation and strong combat power. Once you have it, it's equivalent to carrying a half-immortal bodyguard with you!

Xuanmen actually took out such a precious treasure to exchange, and there was clearly a kind of imperative posture, although it was not explicitly stated, it still faintly revealed a kind of coercion, as if there was a sense of forcing Fang Lie to trade.

This made Fang Lie a little uncomfortable. As a representative of a tendon, Fang Lie naturally didn't bow his head lightly, he frowned and thought about it, and then asked directly, "I want to know what that thing of mine has mutated into?"

Qingfeng and Mingyue glanced at each other, and there was a wry smile in their eyes.

Then Qingfeng said helplessly: "Don't hide it, after some research from us, we found that the Netherworld Ghost Fire is actually a soul devouring flame, which can burn a qiē substance with aura, whether it is a living creature or a magic weapon, as long as there is aura, it will become its delicious food!"

"You don't need to say this, does it, it seems that the whole world knows about it!" Fang Lie frowned.

"But what others don't know is that when the Nether Ghost Fire is raised to a certain level, it has a wonderful change, not only can it burn aura, but it can also burn spirituality!" Qingfeng said solemnly: "Especially the spirituality in high-level items is its best fuel!"

"Spirituality?" Fang Lie was taken aback when he heard this, and couldn't help but exclaim: "Only magic weapons above the seventh order contain spirituality, isn't it going to be lightly burned by it?"

"That's right, that's true!" Qingfeng smiled bitterly: "We have experimented, the seventh-order magic weapon will be destroyed as soon as it is burned, and the eighth-order magic weapon will not be able to resist at all, just because of the rich spirituality, it needs to be burned for a while." Even if a ninth-order magic weapon encounters this top-level mutated Netherworld Ghost Fire, it will be damaged, although the amplitude is very small, but if it is burned for a long time, it can still cause permanent damage, even if it is completely destroyed, it is not impossible, it is just a matter of time!"

"That's it~" Fang Lie frowned and said, "It seems to be a bit powerful, but even if it can pose a little threat to the ninth-order magic weapon, it's not a big deal, right?"

"Indeed, this characteristic of it, when fighting, is not particularly useful, but it is just a little difficult, but we soon discovered another metamorphosis of it~" Qingfeng said solemnly: "That is, this mutated ghost fire, when burning spirituality, the flame produced also contains a large amount of spirituality, through the special refining technique, these spirituality can be injected into other magic weapons, so as to greatly improve the spirituality of magic weapons!"

"What?" Fang Lie was taken aback when he heard this, and exclaimed, "In this way, wouldn't it be possible to accelerate the growth of the magic weapon?"

"That's true~" Qingfeng said: "We have done a solid thing, burned an eighth-order magic weapon, injected the extracted spirituality into the seventh-order peak magic weapon, and created three eighth-order magic weapons in a row!"

You must know that the reason why high-level magic weapons are scarce is that spirituality is difficult to find, unless there is an opportunity against the sky, otherwise, you can only slowly increase your spirituality through guò mana, which is super slow.

Under normal circumstances, the magic weapon of good material refining can grow to the level of the eighth order in tens of thousands of years. If the material is a little worse, it may take hundreds of thousands of years, or even never be able to advance.

As for the ninth-order magic weapon, it can only depend on luck, there are so many sects in the world, and all the ninth-order magic weapons add up, less than a hundred, which shows the preciousness of the ninth-order magic weapon!

And if you can quickly increase the spirituality of the magic weapon, then you can make it advance quickly, which means that you can create a large number of treasures above the eighth order, and this ability may not be described as a metamorphosis. It is no wonder that even such an extremely arrogant sect as Xuanmen did not hesitate to put down his body and seek to leave this treasure behind.

Therefore, after listening to Qingfeng's words, Fang Lie couldn't help but gasp, and then said in surprise: "What a perverted ability, no wonder you are reluctant to give it to me!"

"Hehe, it's true that I'm a little reluctant, so I didn't hesitate to spend my blood and took out Big Brother Black!" Qingfeng said solemnly: "Although the mutated Netherworld Ghost Fire has such an ability to defy the sky, you must also see that the consumption is not small, first of all, the huge loss of spirituality, which is definitely more than seventy percent, so sacrificing an eighth-order mid-grade magic weapon can only give birth to three eighth-order low-grade magic weapons." Moreover, it must be done by the Refining Grandmaster, which can take up to three years. All in all, the benefits are there, but not as much as expected!"

Regarding Qingfeng's statement, Fang Lie didn't say it, but in his heart, he was already about to die.

Indeed, the value of the eighth-order middle-grade magic weapon is invaluable, and the value is only higher than the value of three eighth-order lower-grade magic weapons, and on the surface, such a practice is even a loss.

But don't forget that not all eighth-order magic weapons can be used, especially the treasures with profound spirituality, and they will not recognize the Lord lightly.

Therefore, most of the eighth-order magic weapons of the Demon Dao, the righteous path monks can only see but not use them, and vice versa!

But after having the mutated Netherworld Ghost Fire, it was all different, and the eighth-order magic weapon of the Demon Dao, which could only be used as a meritorious record, suddenly became three eighth-order magic weapons of the Dao Gate that he could use at will, which was just the same as picking it up for nothing!

As for the three years of the Thunder Tribulation Zhenren, what is it compared to the eighth-order magic weapon obtained?

In addition, even if the eighth-order magic weapon of the Demon Dao is consumed, aren't there other spiritual things? The things that contain spirituality are not only magic weapons, but also high-level demons and monks, all of which contain spirituality, and can also be used as fuel.

Nothing else, the corpse of that high-level demon is definitely not rare for Xuanmen.

There are a lot of spatial cracks in this world that are connected to the Demon Domain, and almost every moment is at war with the extraterritorial Heavenly Demons, and all sects have high-level monks involved, in those fierce battlefields, especially when encountering a large-scale invasion of the Heavenly Demons, there will be a mountain of corpses and a sea of blood, and there must be a lot of corpses of high-level demons.

Using these things as fuel to enhance the spirituality of the Dharma Weapon is simply a lucrative job.

As long as Fang Lie is not stupid, he will not be fooled. So he just giggled on the side, but he didn't mean to agree to the deal at all.

As soon as Qingfeng Mingyue saw it, he knew that Fang Lie would not give in lightly, so he could only continue to persuade him: "Brother Fang, we didn't lose you, the ninth-order magic weapon, looking at the whole world, who is willing to trade? Even if it can be bought, it can't be used." But ours is not, as long as you nod, Big Brother Black will immediately confess the Lord with you by dripping blood, and you will suddenly have an extra bodyguard at the level of a half-immortal. This treatment, even if we are promoted to the Thunder Tribulation real person, we may not be able to get it!"

"Yes, you now have a mortal enmity with the Zhuxian God Killer, and you may suffer from the plot anytime and anywhere, although you have an immortal body, you don't want to be killed once if you have nothing to do, right? With Big Brother Black, you can run rampant all over the world, and it will be difficult for the half-immortals of Zhuxian to make a move in the hands of Big Brother Black!" Mingyue smiled and said, "You just agreed! How about I owe you a favor?"

"Don't~" Fang Lie hurriedly waved his hand and said with a smile: "Count me owing you a favor, return my things to me! I am a slut, I am not afraid of death, and I can't afford to use a ninth-order magic weapon." I'm missing a large treasure for travel right now!~"
