The fundamental reason is that there are few extremely precious materials in heaven and earth that can be refined into the immortal-level spiritual objects to form a formation and prohibit them......

In essence, these immortal-level spiritual objects were also created by the Great Dao.

Refining immortal-level spiritual objects into real immortal-level magic weapons is not to refine into the formation prohibition, but to directly create a formation prohibition among the immortal-level spiritual objects.

It's easy to say, but it's an unimaginably large project.

The true evil spirit fire condensed by Chen Xun at this time can only be used to roast sweet potatoes.

If he could quickly condense a large amount of True Evil Spiritual Fire, he would have raised the True Yuan Mana of condensing the Law Body to the level of Immortal Yuan True Evil, so why risk breaking into the sea of chaotic fire to provoke that Black Flame Troll?

The bull-bodied troll with a hideous dragon head can shatter the void with one hoof, and it is too late to hide if it is someone else.

However, Chen Xun couldn't hide, the old thief Xiong Bi in Nanshan was interested in attacking the bull-bodied troll, they wanted to dodge, and when the old thief Xiong Bi in Nanshan succeeded, the strength of the Nanshan War Department would be on a higher level.

Who knows how many innate spirit treasures are bred in the depths of the Sea of Chaos and Fire?

Chen Xun obtained the method of refining Dao Source Divine Thoughts taught by Dao Xu, so he first deduced the basic formation of the Little Heavens Guardian Great Array and the Ten Heavens Chaos Demon Burning Great Array in the Lotus Book Cave Mansion.

Chen Xun sacrificed the Chaos Black Lotus, and the time flow speed in the core area of the Lotus Book Cave Mansion was nearly thirty times faster than that of the outside world, which was also the benefit of cultivating in the depths of the Star Ruins, which could buy him more time to comprehend many secret formations.

Sixty years later, Chen Xun could be regarded as having some understanding of the method of refining Dao Source Divine Thoughts and condensing the True Evil Spiritual Fire.

One hundred and eighty years later, the Chaos Demon re-refined into the Nine Chaos Chains, but there was not enough Chaos True Evil Spiritual Fire, and he still had no way to complete the initial cultivation of the Brahma Realm, and it was useless to stay in the Lotus Book Cave Mansion, so he first went out to help Fang Xiaohan and the Elder Master them refine the twelve-armed Shura Demon God Puppet.

After the Chaos Demon re-cultivated into the Nine Chaos Chains, he passed the White Bone Giant Spear to Emperor Ayin......

The three-headed Emperor Immortal Beast has grown and cultivated in the star ruins with Dao Xuan since he was a child, and he has never thought about transforming into a human body before, and then he will integrate into the Blackshirt Army, as the top combat power of the Blackshirt Army, without one or two top-notch and superb Dao weapons, it is really impossible to bring out his true strength.

The golden pupils and silver pupils don't have any powerful talisman magic weapons or artifacts, but at the moment, they can only consider meeting the needs of the emperor immortal beasts.

The white bone giant spear was only refined to the level of a quasi-peer-grade Dao weapon in the hands of Heavenly Ghost Ge Cheng, and it was extremely difficult to improve it even a little more, just like Jiang Chenge could use it for tens of thousands of years before refining the Five Thunder Escape Empty Bottle into a peerless Dao weapon.

Of course, the difficulty and length of Dao refining are closely related to the cultivation of the refiner, in addition to the need for sufficient extremely precious materials.

It is extremely easy for Brahma realm refiners to refine high-grade and treasure-grade Dao weapons, maybe one can be produced in thirty or fifty years, and it will take about three or five thousand years to refine the best Dao weapons, but if you want to refine a superb Dao weapon, it is no longer a simple matter for all Brahma realm refiners.

Perhaps it will be in the hands of the characters of the Golden Immortal Realm that the refining of the superb Dao weapon will become easy again.

One reason why the Yi people are strong is here.

In addition to the rebellion of the Yi clan against the Emperor Valley Hua, almost all of the other seven Great Emperors of the Desolation have the cultivation of the late stage of the Golden Immortal Realm, over the years, who knows how many superb Dao weapons they have refined in their hands and passed them on to their disciples and generals?

And the Tianjun Realm Human Race has risen for millions of years, and the peerless-grade Dao weapons refined by the Brahma Immortal Monarch of the Tianjun Realm are no more than ten pieces when they are fully counted.

Although the sixth patriarch of the Brahma Realm also cultivated to the Golden Immortal, his stay in the Tianjun Realm was too short, and in addition to the immortal-level magic weapon Eight Scenery Heavenly Lanterns, there were not many superb Dao weapons to pass on to the descendants of the Brahma Palace.

At this time, Chen Xun once again became an outlier in the Seven Domains.

His divine soul is not slightly weaker than the strong man of the Golden Immortal Realm, and he has mastered the Yi Clan's Ten Thousand Weapons Perfection True Method, and the refining of the superb Dao weapon in his hands is definitely much faster than in the hands of Fang Xiaohan and Jiang Chenge, but if you want all the black-shirted soldiers to hold the pure Yang Dao weapon, it will also take a long time to accumulate.

It wasn't until the two hundred and forty years that Chen Xun condensed a little bit of the Chaos True Demon Spiritual Fire that could really incinerate the void, and Chen Xun first refined this Chaos True Demon Spiritual Fire into the Chaos Yuan Void Mirror, helping Emperor Xuan Ah Sword to comprehend the last formation prohibition of the Chaos Yuan Mirror, and at this time, Chen Xun could officially try to refine the Ten Heavens Chaos Demon Burning Array into the Chaos Black Lotus, or repair the defects of the Little Heavens Guardian Array in the Lotus Book.

Chen Xun decided to refine the basic formation of the Ten Days Chaos Demon Incineration Array into the Chaos Black Lotus first.

But it's not that the Little Heavens Guardian Array is not important, the Little Heavens Guardian Array is fully repaired, which can not only make the space of the Lotus Book Cave Mansion more solid, but also provide an indestructible protective array for the Blackshirt Army when it encounters the enemy, and first gain a foothold in an invincible position, but it is not an easy task for the Little Heavens Guardian Array to repair it completely.

Chen Xun spent sixty years thoroughly comprehending the basic formation of the Ten Days Chaos Demon Burning Great Array, but it was another two hundred and forty years since he truly refined the basic formation of the Chaos Demon Burning Great Array into the Chaos Black Lotus.

Chen Xun stepped out of the Lotus Book Cave Mansion, and only eighteen years had passed on the Tianquan Star Core.

"Success?"

Seeing Chen Xun coming out, Fang Xiaohan, Shi Shi, Xu Zheng, Jia Dai and others all surrounded him.

"It's a preliminary success...... Chen Xun sacrificed the Chaos Black Lotus and showed it to everyone to watch.

In the past, the Chaos Black Lotus seemed to be carved from black jade, and the Chaos Black Flame was like a pure black liquid stored in the lotus heart, and after refining into the basic formation of the Ten Days Chaos Demon Burning Demon Array, the Chaos Black Lotus condensed the dark golden edge in the edge area of the leaf petals, and it was very agile, as if there were hundreds of tiny dragons rolling and roaring in the lotus leaves, and bursts of unimaginable destructive power were swallowed in the lotus leaves, and the Chaos Black Flame in the lotus heart no longer existed, replaced by a tower between the real and the virtual. In the alien space composed of the Ten Heavens Chaos Demon Burning Array, I saw endless chaotic demonic qi tumbling and surging in this alien dimension......

"Refining into the Ten Days Chaos Demon Incineration Array, it has directly broken the previous restriction that the Chaos Black Lotus can only store twenty-seven Tribulation Thunders, and for this alone, the power of the Spirit Lotus will be increased several times......" The master said with a sigh of amazement, and anyone could see that the endless Chaos Demon Qi in the space of the Great Array was actually several times more majestic than the Chaos Black Flame stored in the Lotus Heart before.

"If you sacrifice the Imperial Spirit Lotus at this time, can you resist several more world-destroying tribulation thunders at the same time?" Jia Dai asked curiously, this involved the issue of Chen Xun's instantaneous attack power explosion.

The Nine World-Destroying Tribulations thundered together, Chen Xun was able to directly disperse the divine soul aura that the Brahma Realm powerhouse had refined into the best Dao weapon, and he could crush the treasure-grade Dao weapon without accident, such an attack was already extremely powerful, but it could not form a fatal threat to the bull body trolls of the Huaijin Immortal Realm.

The body of the gods and demons of the bull body troll is as strong as a superb Taoist weapon.

In addition to the siege and water grinding to consume the demon yuan mana of the ox-body troll and entangle it to death, even if the Brahma Realm Xuan Xiu has many peerless Dao weapons, no one has the ability to directly destroy the body of the bull-body troll comparable to the peerless Dao weapon - even if Chen Xun can control the nine world-destroying tribulation thunders at the same time, it is difficult to inflict a heavy blow on the bull-body troll in an instant.

"Look ......"

To besiege and kill the bull-bodied trolls, everyone needs to work together, and Chen Xun is showing the magical power of the Chaos Black Lotus at this time, so naturally he can't hide anything.

He saw a newly dragged black meteorite next to the Tianquan Star Core, so he sacrificed the Chaos Black Lotus to the black meteorite cover, and at this time, he saw the lotus petals unfolding from the inside of the Chaos Black Lotus layer by layer, turning into a chaotic space to wrap the black meteorite inside, and the endless chaotic demonic qi exploded together......

When the lotus petals faded down layer by layer, the black meteorite was gone, and the remaining pure gold and exotic iron that could not be destroyed in an instant by a few chaotic tribulation thunders were scattered there.

That black meteorite is thousands of miles in circumference, as if a giant peak is lying in the void, but it can always exist in the depths of the star ruins, it is really a thousand times stronger than an ordinary stone peak, who would have thought that it would be wiped out under the instantaneous wrapping of the Chaos Black Lotus, and there would not even be much residue left?

"Non-peerless Dao weapons can't resist it!" Xu Zheng was amazed.

Xu Zheng secretly felt that even if he succeeded in cultivating the immeasurable and invincible Dharma Body and advancing to the Brahma realm, even if the two reincarnation remnant tablets were immortal-level remnant treasures, in front of the re-refined Chaos Black Lotus, maybe he could only guarantee that the remnant soul could escape into reincarnation, right?

"The Chaos Black Lotus was previously a spiritual creature born in the Star Ruins, and after refining, it has truly become an immortal magic weapon, and it should always have a new name. Fang Xiaohan said with a smile.

"Ten Heavens Chaos Demon Burning Spirit Lotus, this name is ...... majestic," Chihai leaned over and said.

"How can you be so trouble-free?" Chen Xun laughed, took the Chaos Black Lotus into his hand, looked at the endless dim gray mist, and said with a solemn expression, "Although the depths of this star ruin may hide the secret of the Thirty-Three Days, it has also made many Golden Immortal Realm powers in the Seven Domains hide here, and no one in the Seven Domains presides over it, so many disasters have been suffered. I hope that on the day when I finally refine the Spirit Lotus, I will burn through this gray sky dome and see what kind of secrets are hidden behind the space-time passage - if you want me to say, this Spirit Lotus will be called the Burning Sky Treasure Lotus in the future......"

"Okay!" Dao Xuan condensed his body in front of everyone and applauded loudly, his mind that had been trapped in the Heavenly Power Star Core for millions of years and had been wiped out suddenly became agitated again, and said, "I will definitely burn this heavenly dome and see what it looks like in the thirty-three days after the space-time passage!"

"Burning Heaven Treasure Lotus!" Fang Xiaohan and the Elder Master muttered to themselves, they all thought that this name was good, thinking that Brahma Treasure Lotus had only gone through preliminary refining, and he already had such power, he might be able to burn the sky and destroy the gods one day.

Chen Xun secretly said that the Burning Heaven Treasure Lotus was in his hands, and he was already able to directly destroy the top-grade Dao weapon, even if the body of the ox-bodied troll was really as strong as a peerless Dao weapon, it was impossible for them to be unharmed under the attack of the Burning Heaven Treasure Lotus, it was time for them to make the next move.
