Duan Chen walked around the Demon Flame Pool, nodded with satisfaction, and immediately took out a magic weapon from the storage ring, the Dust Extinguishing Aurora Mirror.

This high-grade magic weapon was once sold by him to the Black Dragon Master through auction, but later he attacked the Black Dragon Master and recaptured this magic weapon.

Of course, the reason why Duan Chen chose to use the Dust Extinguishing Aurora Mirror to refine the magic treasure was mainly because he had never used this magic weapon in front of outsiders before, so he didn't have to worry about being recognized.

Moreover, the Dust Destroying Aurora Mirror is a top-grade magic weapon, if it is used to refine magic treasures, as long as it does not fail, the grade can at least reach the level of high-grade magic treasures.

However, if you want to refine the Dust Extinguishing Aurora Mirror into a magic treasure, in addition to the Dust Extinguishing Aurora Mirror itself, you also need the assistance of many other magic materials.

Soon, under the guidance of the Seven Demon Lords, Duan Chen screened out the most suitable materials for refining magic treasures with the Dust Extinguishing Aurora Mirror from the magic materials he had just purchased, a bottle of spiritual washing water, three magic pattern stones, and a small bottle of black demon essence blood.

Among them, the most expensive was the black devil essence blood refined from the black devil crocodile blood, just a small bottle of black devil essence blood cost Duan Chen nearly 170,000 medium-grade magic stones.

However, the value of the Dark Spirit's blood is also worth the price.

The adult black devil crocodile is an extremely powerful demonic beast in the Southern Regions, and its strength is not weaker than that of the Demon Emperor Realm, and only monks above the god transformation stage have the strength to hunt and kill, so the price of the black devil essence blood refined from the blood of the black devil crocodile is relatively expensive.

Of course, the reason why the price of black magic essence blood is so expensive, in addition to the strength of the black magic crocodile itself, which is difficult to hunt, is also an important reason.

The destructive power contained in the blood of the black magic crocodile is very similar to the dust extinguishing aurora contained in the dust extinguishing aurora mirror itself.

Therefore, if you add a little black demon essence blood when refining the magic treasure with the Dust Extinguishing Aurora Mirror, you can greatly increase the power of the Dust Extinguishing Aurora.

"Let's get started. Inside the mountains and rivers, the Seven Demon Lords said lightly.

Duan Chen took a deep breath and threw the Dust Extinguishing Aurora Mirror in his hand into the Demon Flame Pool, and the surging white Demon Flame immediately enveloped the entire Dust Extinguishing Aurora Mirror.

Soon, the spirit patterns engraved on the surface of the Dust Extinguishing Aurora Mirror began to melt.

"First use the spirit washing water to wash off the spirit pattern brand on the dust extinguishing aurora mirror, then use the magic pattern stone to engrave the magic pattern, and finally use the black demon essence blood. ”

Almost as soon as the spirit patterns engraved on the surface of the Dust Extinguishing Aurora Mirror began to melt, the voice of the Seven Demon Lords sounded in Duan Chen's mind in an orderly manner.

Duan Chen didn't dare to be careless, and immediately poured the entire bottle of spiritual washing water into the Demon Flame Pool.

It can be seen that under the wrapping of the white magic flame, the spirit washing water not only did not evaporate instantly, but quickly integrated into the dust extinguishing aurora mirror, greatly speeding up the melting speed of the spirit pattern on the surface of the mirror.

In just half an hour, all the spiritual patterns originally engraved on the surface of the dust-killing aurora mirror were washed away by the spirit washing water, and the surface was smooth and smooth, looking like an ordinary mirror.

Seeing this, Duan Chen immediately threw the three demonic stones he had prepared in advance into the demonic flame pool, and the pale demonic flames quickly wrapped the three demonic stones, and within half an hour, the three demonic stones melted into a pool of silver-gray demonic liquid.

The silver-gray magic liquid emits a faint glow, full of magic.

However, Duan Chen didn't dare to pause in the slightest, he suddenly raised his hands and continued to play various magic tricks, and one after another magic light flew out of his hand and submerged into the demon flame pool.

If a Terran cultivator who was proficient in refining magic weapons witnessed this scene, he would definitely be surprised.

Because Duan Chen actually used the method of refining magic weapons to refine magic treasures.

However, unlike refining magic weapons, what Duan Chen wanted to engrave on the Dust Extinguishing Aurora Mirror next was not a spirit pattern, but a magic pattern!

The process of inscribed the magic pattern is very cumbersome, and the higher the level of the magic treasure refined, the more complicated the magic pattern that needs to be engraved, and this work alone took Duan Chen nearly three days.

Even if he has broken through to the late Yuan Infant stage now, and his mana is strong, he feels a little unbearable.

Fortunately, so far, everything is going according to his and the Seven Demon Lords' plan, and nothing has gone wrong.

Airplanes!

When the last magic pattern was engraved, the magic light on the surface of the entire dust extinguishing aurora mirror flashed, and the original snow-bright mirror surface suddenly turned into pitch black, and continued to bubble with demonic energy, as if it had been transformed from a magic weapon to a magic treasure.

However, Duan Chen still didn't dare to relax in the slightest, his expression was focused, and while seizing the time to recover the magic power in his body, he took out the small bottle of black demon essence blood worth 170,000 medium-grade magic stones.

However, he was not in a hurry to immediately integrate the black devil essence blood into the Dust Destroying Aurora Mirror, but crossed his knees like an old monk and meditated and breathed.

Half an hour later, Duan Chen reopened his eyes, and the tiredness on his face was swept away.

It was only at this time that he carefully poured the bottle of black demon essence blood into the demon flame pool, and quickly played a series of magic tricks to speed up the speed at which the dust extinguishing aurora mirror absorbed the black demon essence blood.

I saw that in the Demon Flame Pool, the Dust Extinguishing Aurora Mirror greedily absorbed every drop of black demon essence blood, and with each drop, the demonic energy around the Dust Extinguishing Aurora Mirror became heavier, and the magic patterns engraved on the mirror were also dyed with a layer of blood light.

Time flies.

When the last drop of black demon essence blood was absorbed by the Dust Extinguishing Aurora Mirror, he saw that the magic pattern engraved on the surface of the Dust Extinguishing Aurora Mirror had already turned into a blood-red color, exuding a strong demonic power, which made Duan Chen feel overjoyed.

However, at this moment, a change suddenly occurred.

I saw that on the dark mirror surface of the Dust Extinguishing Aurora Mirror, ripples suddenly rippled round after circle, and a whirlpool suddenly appeared on the surface of the mirror, frantically swallowing the white demon flame in the demon flame pool.

It can be seen that wisps of white demonic flames have submerged into the Dust Extinguishing Aurora Mirror, which is like a bottomless pit, and those who come do not refuse, constantly devouring the white demonic flames inside the demonic flame pool.

After a while, the surging white demonic flames in the entire Demon Flame Pool were swallowed up by the Dust Extinguishing Aurora Mirror.

It was only at this time that the Dust Extinguishing Aurora Mirror seemed to be full, slowing down its devouring speed of the White Demon Flame, but it was still slowly absorbing.

Seeing this, Duan Chen couldn't help but ask with a look of surprise, "Senior, how could this Dust Exterminating Aurora Mirror suddenly devour the Demon Flame in the Demon Flame Pool?"

The Seven Demon Lord was a little uncertain and said, "It should be the relationship between the black devil essence and blood." ”

After a slight pause, he continued: "The black devil essence blood is refined from the blood of the black devil crocodile, and it contains the fierce aura of the black devil crocodile. ”

"Seniors say demonic?" Duan Chen's eyes lit up: "Doesn't that mean that the Dust Destroying Aurora Mirror has now been promoted to a spiritual treasure?"

"Lingbao? It's not that easy. The Seven Demon Lords shook their heads and said, "Whether it is a magic weapon or a magic treasure, a complete instrument spirit must be born in order to be promoted to a spirit treasure, and it is not a spirit treasure if it only has a trace of demonic nature." ”

After a slight pause, he continued: "But your luck is not bad, although this Dust Exterminating Aurora Mirror has not yet been promoted to a spirit treasure, but because of the absorption of the blood of the black devil essence, it has now reached the level of the best magic treasure." ”

"And because the Dust Extinguishing Aurora Mirror has given birth to a demonic relationship, as long as this trace of demonic nature continues to grow, sooner or later it will transform into a demon spirit, and then the Dust Extinguishing Aurora Mirror will naturally be promoted to a spiritual treasure. ”

The moment he heard that the Dust Extinguishing Aurora Mirror was not directly promoted to a spirit treasure, although Duan Chen was slightly disappointed, he was not too frustrated.

After all, the Dust Extinguishing Aurora Mirror was originally just a top-grade magic weapon, but now that it has been retrained, it can reach the level of the best magic treasure, which is already an unexpected joy for him, not to mention that there is also a trace of magic inside it, and there is room for promotion to a spiritual treasure in the future.

Thinking of this, the original disappointment in Duan Chen's heart also disappeared.

It was only at this time that he focused his attention on the Dust Extinguishing Aurora Mirror after being refined.

However, the palm-sized dust extinguishing aurora mirror has a dark surface, smooth as water, and the inside is faintly visible with blood-red magic patterns flickering, which is demonic.

And the magic power it exudes has also reached the level of the best magic treasure.

Speaking of which, this Dust Exterminating Aurora Mirror was still the first top-grade magic treasure that Duan Chen had, and it was also refined by him himself, which was of great significance.

He wanted to test the current power of the Dust Extinguishing Aurora Mirror, but considering that this was the Demon Weapon Pavilion, if it caused damage to this place, it would inevitably cause a lot of unnecessary trouble, so he dispelled this idea and instead summoned the Blood Demon Banner from his body.

This time he rented the Demon Flame Pool of the Demon Weapon Pavilion, Duan Chen did not plan to refine only one magic treasure, in addition to the Dust Extinguishing Aurora Mirror, he also planned to refine his second natal magic weapon, that is, the Blood Demon Flag, into a magic treasure.

Compared to refining the Dust Extinguishing Aurora Mirror into a magic treasure, refining a magic treasure with the Blood Demon Banner is more complicated, after all, this is Duan Chen's second natal magic weapon, and it is also the natal magic treasure of his demon path deity in the future, and there is no room for sloppiness.

Whether it is in the aspect of inscription magic patterns or the required magic materials, we must strive for excellence.

Therefore, the preparatory work alone took Duan Chen seven days, and as for the magic stones spent on the purchase of magic materials, it was as much as 500,000.

If it weren't for the fact that he had gambled a lot and earned a lot of magic stones, he might not have been able to take out so many magic stones to buy materials for a while.

When all the preparations were completed, Duan Chen began to refine the Blood Demon Banner under the guidance of the Seven Demon Demons.

Time passed little by little.

In the City Lord's Mansion, in the Demon Clan's Embassy Station, the purple-eyed Lion King glanced at the Zhu Yan Demon King who was sitting leisurely in the courtyard, and frowned slightly: "You have been very idle these days, why, everything has been investigated clearly?"

Zhu Yan Demon King laughed: "If you want to hurry, you can't reach it, and occasionally you still have to rest for a day or two." ”

"Don't forget, our mission to the Southern Regions is complete. The Purple-Eyed Lion King said coldly, "We haven't found Duan Chen yet!"

"Don't be in a hurry. Zhu Yan Demon King waved his hand and motioned for the Purple-Eyed Lion King to sit down and speak.
