Previously, although the strength of the five Heavenly Martial Arts masters was extraordinary, because they didn't know how to crack it, they were finally seriously injured and died outside as soon as they escaped.

Now, Lu Yu spent a stick of incense and luckily passed through this array and came to a burning cave.

The rocks on the ground were as crystal clear as jade, and there was a dark red liquid flowing inside, and there were mysterious lines that flashed and disappeared.

At the end of the cave, on a raised stone, there was a blood hole with a diameter of one foot, erupting raging flames, like a dragon in mid-air, unpredictable.

"Fire Eye!"

Lu Yu exclaimed, his expression was excited, the fire eye in the center of the earth is a treasure of heaven and earth, and it is extremely rare.

The high temperature in the cave burns the gods, destroying life at all times, making it impossible for people to stay here for a long time.

The pillar of fire erupting in the eye of the fire was colorful, turning into a dragon, looking down on Lu Yu.

On the dragon's head, there is a colorful flame, which is intertwined by seven kinds of runes, and it is unpredictable.

Lu Yu's eyes were like torches, staring at the colorful flames, and he was extremely excited.

"Colorful glaze, the extreme of rune fire! This is the Seven Treasure Rune Flame!"

Lu Yu blurted out exclaimed, he didn't expect to encounter the legendary supreme rune fire here, the Seven Treasure Rune Flame!

According to legend, this is a kind of flame bred by seven innate runes, and it is the top flame for refining runes, which is rare and eternal in ancient times.

This Seven Treasure Runic Flame is extremely mysterious, it is a super evolved fusion flame, which is different from ordinary different fires, spiritual fires, Dan fires, and soul fires, and has multiple effects, and can refine the strongest runes.

It can be said that it is a difficult time to fuse the Seven Treasure Rune Flames.

Although Lu Yu was a talisman master, he didn't know how to fuse.

Lu Yu only understood one thing, forcibly fusing the Seven Treasure Fu Flame was tantamount to looking for death.

Not to mention that the Heavenly Martial Arts master can't complete it, even the peak master of the Divine Dao will also die in the hands of the Seven Treasure Rune Flame.

Therefore, although Lu Yu came here, the chance of being able to fuse the Seven Treasure Rune Flame was less than one percent.

That's unattainable, and it's a pity.

The pool of ten thousand laws is shaking, analyzing and deducing, and wants to find a way to solve it.

The Beidou system is also running at full capacity, combined with Lu Yu's situation, to calculate whether there is a chance of success.

The location of the Fire Eye contains a powerful fire aura, which is very suitable for Lu Yu's cultivation.

But if he couldn't obtain the Seven Treasure Rune Flame, it would be difficult for Lu Yu to stay here for a long time.

In contemplation, the heavenly veins awakened, and the primordial light accelerated in the Jiuyang Shenmu Ding, releasing a special breath that followed Lu Yu's right arm and reached the palm of his right hand.

At that moment, the sleeping Bliss Knife in Lu Yu's palm was awakened, and the Heavenly Shadow Crystal Flame on the tip of the knife flickered endlessly, and he actually had a strong interest in the Seven Treasure Rune Flame.

The Bliss Knife vibrated and released a mysterious force, and a knife technique took shape in Lu Yu's mind!

"Ten Thousand Dao Extreme Yang!"

This is the first of the three forms of bliss, Lu Yu has tried to cultivate, but he has never performed it.

The Ten Thousand Law Pools shook, combined with the fluctuations of the Bliss Knife, and quickly came to a conclusion.

With Lu Yu's current situation, if he wanted to fuse the Seven Treasure Rune Flames, he had to use the Bliss Knife to complete it.

Among them, it involves the Heavenly Shadow Crystal Flame and the Ten Thousand Dao Extreme Yang.

The Seven Treasure Runic Flame could only be integrated into Lu Yu's right palm, suppressed with the help of the Bliss Knife, and guided by the Heavenly Shadow Crystal Flame.

Lu Yu was very excited, focused on analysis and deduction, repeated calculations, and only after confirming that it was feasible, did he start to prepare.

The method is very simple, Lu Yu only needs to cast the Ten Thousand Dao Extreme Yang, and with the help of the guidance of the Heavenly Shadow Crystal Flame, combined with the smelting of the Ten Thousand Law Pool, he can integrate the Seven Treasure Runic Flame into the palm of his right hand.

After that, it needs to be suppressed with the help of the Bliss Knife, and slowly refine the Seven Treasure Runic Flame and integrate it into itself.

According to the calculation of the Ten Thousand Law Pool, once Lu Yu fused the Seven Treasure Rune Flames, he would be able to cast the domineering mastery of the Ten Thousand Dao Extreme Yang.

This move is extremely terrifying, and its power is by no means under the palm of the Black Moon Heavenly Buddha, or even more so.

At present, it is still very difficult for Lu Yu to cast the Ten Thousand Dao Extreme Yang, because his realm is not enough.

But Lu Yu has a lot of pills in his hands, and combined with the Nine Turns of Collapse, there is still hope.

"It's a gamble!"

Lu Yu took a large number of Xuanyuan Pills, and the first weight of the Nine Turns Collapse Heaven was running, the divine body was recovering, the ten veins were penetrated, and the lifelong potential was stimulated, and the right hand was slowly pushed out, and the light in the palm of the palm surged.

The sword flashes, and the blissful knife appears!

Lu Yu's whole body divine pattern bloomed, and the Great Dao divine sound in his body was roaring, as if the god king had descended, triggering a vision.

The chaotic green lotus in the dantian divine aperture released the chaotic light, the Baichuan veins trembled, the Shenmu Ding shook, and every inch of muscle, every muscle and bone, and every drop of blood were glowing.

All kinds of forces in Lu Yu's body are transforming, converging in the dantian divine aperture, whether it is the power of yin and yang, the power of the five elements, or the power of other attributes, they are all transformed into the power of the supreme yang and the strong, the supreme and the strong.

This is the Ten Thousand Dao Extreme Yang, transforming all power into the power of the Extreme Yang, and all the Dao are of the same origin.

The Bliss Knife trembled, as if a real dragon was flying into the sky, shaking Lu Yu's mouth and splashing divine blood.

The blade is shining, drowning all the light in the world, and the power of the extreme sun is pouring over the ages, like the eternal sun, traversing the ancient and modern future!

That knife, heavy as the sky, almost crushed Lu Yu's body and broke the meridians of his body.

That knife, incomparably brilliant and rare in the ages, lit up the wishes of the heavens.

That sword, all ways obey, only I am undefeated, cutting off the world's mortal edge.

That knife led the times, destroyed the heavens, and stood at the top of all paths.

The caverns are roaring, and the eyes of fire are crumbling.

The seven-colored Seven Treasure Runic Flame was like a mad dragon, fighting, roaring, but it was suppressed by the Dragon Slaying Knife.

Lu Yu's divine body origin was seriously depleted, and this sword overdrew his life's strength, and the Baichuan veins were about to wither.

The divine power was depleting, the martial soul was collapsing, and the medicinal power contained in the Xuanyuan Pill was instantly emptied, and Lu Yu felt that he was about to die.

Ten thousand Dao Extreme Yang, the blade collapsed into the sky, and at the moment of slashing, the entire fire eye was located, the flames danced wildly, the Fu Flame lamented, and hundreds of millions of flames turned into a rain of fire, and the origin was dissipating, forming an absolute suppression.

The Seven Treasure Runic Flame was twisted and deformed, like a true dragon that wanted to fly into the sky, but was stopped by the power of the extreme yang.

The Bliss Knife flickered with the light of the Heavenly Darkness, combined with the Ten Thousand Magic Pools of the Little Grass Martial Soul, forming a kind of strong pressure and temptation, so that the Seven Treasure Runic Flame was forced to fly towards the Bliss Sword when it was difficult to resist.

The Ten Thousand Magic Pool trembled, releasing a mysterious light that wrapped around the Seven Treasure Runic Flames.

The Heavenly Shadow Crystal Flame flashed quickly, playing a leading role, and with the smelting guidance of the Ten Thousand Law Pool, the Seven Treasure Runic Flame was ingested into the palm of Lu Yu's right hand in one fell swoop.

In the next second, the Bliss Knife turned back, like a big seal, sealing the chaotic Seven Treasure Runic Flame there and forcibly suppressing it.

Lu Yu collapsed, fell to the ground, and took five elixirs in a row, but he couldn't resist the tiredness of his body.

The Eye of Fire was erupting, and after losing the Seven Treasure Rune Flame, it became extremely unstable, as if it could collapse at any moment.

Lu Yu struggled to get up and slowly cast the Beidou Divine Fist, feeling the scorching flames transform into the Qi of the Sun, soothing the tiredness of his body.
