With a slight sense of weightlessness, Lu Kun opened his eyes and looked around, this kind of short-distance teleportation, he didn't need any teleportation runes at all, and his physical body could easily withstand it.

It is a semicircular cave about the size of a stone house, with a curved gray rock wall in front of it and a stone gate three feet wide on top.

On the right side of the stone gate, there is a circular groove, which looks like a socket for some kind of key, and above the stone door, there are four ancient characters carved with "Rongyuan Demon Cave".

The entire arc-shaped gray wall, as well as the rock wall on the ground and the top, did not have any prohibitions, only the cracks in the stone gate, leaking extremely pure demonic energy.

Lu Kun exclaimed: "The cave built by the Broken Dragon Stone seems to be the handiwork of the Yiyuan Sect, and the Demon Refining Cave in the Yiyuan Secret Realm is made of the Broken Dragon Stone, but the demonic energy overflowing from the stone gate does not seem to have the breath of true demonism." ”

Then he left the teleportation array at his feet and looked behind him, where there was a black wall, shrouded in a layer of prohibition, slowly absorbing the demonic energy in the cave.

Lu Kun's eyes flashed with gold: "The wall composed of the Demon Chalcedony Stone should have been built by the Demon Spirit Gate." ”

Thinking of this, he stepped forward and raised his right arm, the muscles on it bulging one by one, rapidly expanding, and the piercing silver swirls suspended on the thick fingers.

"Poof".

This layer of prohibition is only at the mid-stage level of the Yuan Infant, and it does not come with the vitality of heaven and earth, so naturally it can't stop Lu Kun's whirlpool finger, and a gap is broken, and the aura slowly dissipates.

Lu Kun pushed open the forbidden wooden door, looked at it, and showed a look of surprise: "Sure enough, it is the treasure of the Demon Spirit Gate." ”

This is a semicircular room that is not big or small, except for the prohibition broken by Lu Kun, the other walls are also made of broken dragon stones, obviously the Demon Spirit Gate has divided this broken dragon stone cave into two halves.

Six shelves stood inside, and a series of forbidden light curtains shrouded all kinds of treasures inside, in addition to jade slips, pill bottles, magic weapons, and a shelf with a layer of storage bags and storage bracelets.

Lu Kun walked to the first shelf, where a magic gathering array was set up, and a rich demonic aura shrouded the materials inside.

"Tsk, there are actually as many as sixteen demon bones, and four of them are still at the level of a demon general, hey, this is a magic stone that has reached the level of a magic pith diamond, and this ......"

Lu Kun was dazzled, he had collected a large number of magic treasure refining methods in the Qi country, and he knew the demon path refining materials by heart, but the top level demon path materials in front of him were several that were completely suitable for the refining of battle treasures.

The next shelf was shrouded in an isolation circle, isolating the demonic energy, and it was full of sparkling magic weapon materials.

"Dazzling Crystal, Extreme Flame Stone, etc., this seems to be a Gengjin Stone!"

Lu Kun reached in and took out two golden stones the size of walnuts, and a strong sharp aura could be clearly felt in the palm of his hand, as if it was about to tear his skin.

"If Yue Longfei wants to see Geng Jinshi, I'm afraid his mouth will smile crookedly, as long as he refines a little into the sword treasure, the power of the sword magic weapon will immediately surge by several percent. ”

Lu Kun had a flash of inspiration in his hand, and the Gengjin stone was received by him in the ribs, and he glanced back, he skipped the shelf of the magic treasure and looked at the jade slip in the back row.

"Chaos Five Elements Great Array", "Demon Spirit Mixed Yuan Jue", "Demon Spirit Codex", "Ancient Refinery Law", ......

casually glanced at a few jade slips, which made Lu Kun excited.

The simplified Chaos Five Elements Great Array, which he had seen as early as the Battle of Shangqing Gate, was a magic array that used the chaotic Five Elements Aura to strengthen defense.

It is said that when the monks of the Ancient Transformation God Stage were fighting, they were all within the Chaos Five Elements Great Array, and the Heaven and Earth Yuan Qi and Chaotic Aura stirred by such strong people would instead strengthen the defenses of the Great Array.

"It's the Five Elements of Chaos, I don't know if it has anything to do with my Five Elements Chaos Demon Body?"

Lu Kun took a brief look and found that the content in it was somewhat related to the power of the Great Five Elements, which was obscure and difficult to understand, and it was obviously not something that could be understood in a short time.

Then he picked up the Demon Spirit Mixing Essence Recipe again, and after only reading it for a while, he immersed himself in it.

This technique is really wonderful, although it is a practice for cultivating magic power, but the core is to cultivate a temporary mana called Rongyuan spiritual power.

This kind of mana is to absorb a large number of spirit stones through a special magic circle, and then catalyze the generation, which can accelerate the cultivation of magic power.

The pair of jade villains intercepted by Lu Kun are called Rongyuan Jade Infant and Rongyuan Demon Infant respectively, and Rongyuan Jade Infant is Shi Shocking Natal Magic Weapon, because only the existence of this treasure can Rongyuan spiritual power accelerate the cultivation of the Yuan Infant Stage.

The Rongyuan Demon Infant is an auxiliary magic weapon, which has the effect of storing magic power, and it can also perform a lot of unique magical powers when combined with the Rongyuan Jade Baby.

What amazed Lu Kun was that this exercise described a magic array called the Demon Suppression Array, which actually had the effect of resisting the true demon, but the spirit stones it consumed were also extremely terrifying, and they were all high-grade spirit stones.

Now it seems that the great elders of the Demon Spirit Sect are all big consumers of spirit stones, and Shi Jingtian can enter the realm of the Great Cultivator, it should be with the resources of Yueyang Sect that he activated the Demon Suppression Array, and only then did he rely on the True Demon Water to break through.

In addition to the astonishing cultivation speed, the other magical powers of the Demon Spirit Mixing Yuan Technique are not simple, and the magic power combined with the Fusion Yuan spiritual power can carry the power of destruction in the attack.

Lu Kun pondered: "The destructive power that Shi Shocking Heaven unleashes is somewhat similar to the demonic energy generated, but it is also a little different. ”

A flash of inspiration flashed in his hand, and a black and white jade ruler appeared.

"The main material of this treasure is the same as the Rongyuan Jade Infant and the Demon Baby, and they are all Rongyuan Magic Stones. ”

While thinking about it, a silver light flashed in Lu Kun's hand, and the magic energy was injected into this magic weapon by him.

The next moment, the Demon Spirit Ruler trembled violently, and a slight cracking sound came from inside, and the spiritual light became extremely dim.

Lu Kun's eyes flashed with gold, and he was a little surprised: "The magic circle inside can't withstand the domineering magic energy, but the magic energy seems to be able to be transmitted smoothly inside, is it because of the Rongyuan magic stone?"

"At the beginning, Yueyang Sect was destroyed, and several senior brothers were planted with Rongyuan Demon Qi in their bodies, and the Rongyuan Magic Stone is said to be a unique material in the Demon Yuan, it is also called a Magic Stone, can it be said ......?"

Thinking of this, he looked at the jade slip behind him again, flipped to a "Secret of the Demon Abyss", and looked at it intently.

After a while, Lu Kun showed excitement, he put away the jade slip, walked out of this treasure house, and came to the Duan Longshi Gate on the other side of the cave,

Looking at the four big characters of "Rongyuan Demon Cave", Lu Kun squatted down, and inserted his fingers into the gap at the bottom of the stone door, accompanied by a rumbling sound, this huge broken dragon stone that was one foot thick was lifted up by a small palm.

The Broken Dragon Stone is inherently isolated from all kinds of spells, and the immortal cultivators can only bombard it through powerful magic weapons, and the stone gate in front of them is full of a zhang thick, even if the Yuan Infant Stage cultivators keep attacking, it will take an extremely long time.

But for Lu Kun, this broken dragon stone is only 200,000 catties, even if it is a bone treasure period body cultivation, it can be lifted by the body, so it can be easily entered without a key.

With the Broken Dragon Stone falling violently, Lu Kun came to a cave dozens of zhang in size.

On the four walls of the cave, there are nine dragon heads spitting out white spirit pillars, and the purest spiritual energy contained in them is actually the purest spiritual energy.

And these nine white spirit pillars spewed towards the center, forming a white ball with a diameter of several zhang, enveloping the magic pool in the middle that was one zhang long and wide.

The purple-black true demonic qi rising from the demon pool was intertwined with the white spirit pillar, and the demonic qi that penetrated from the white ball did not have any true demonic aura.

The ground at the junction of the True Demon Qi and the White Sphere was both black and white, which looked very weird.

Lu Kun muttered: "Sure enough, it is the place where the Yiyuan Sect tries to destroy the water of the true demon, and there is no use of demonic energy here, and it simply relies on pure spiritual energy. ”

When he saw the pool of True Demon Water that was almost full, he sighed lightly and said, "It's a pity that it didn't succeed, so it can only suppress the True Demon Qi and hinder its spread,"

Lu Kun looked at the black and white ground outside the Demon Pool, combined with the description in "The Secret of the Demon Abyss", and muttered: "I don't know if the Yiyuan Sect expected that the long-term erosion of the pure spiritual energy and true demonic qi here has generated the unique material of the Rongyuan Demon Stone. ”
