The physical body can be compared to the pure-blooded beings in the god and demon realm, such an evaluation is undoubtedly very amazing.

Lu Feng's cultivation attaches great importance to the physical body, he cultivates the Immortal Burning Recipe and the Immortal Robbery Technique, the tempering of the physical body is quite thorough, and he has experienced the baptism of the Immortal Spirit Spring, and has eaten a lot of treasures that surpass the holy products, and I don't know how many of the best holy medicines, the physical body is holy, and it is incomparably strong.

And the Shengxuan Fruit, the ancient elixir of the gods and demons realm, caused Lu Feng's physical body to undergo a great transformation, tending to perfection, and gradually surpassing the sainthood, approaching the level of the god level.

He was so badly injured, his body was tattered, and he was almost destroyed, but he was able to recover to an intact state after the injuries of Jiu Youque and Xu Man recovered for a few days, all because of this ancient elixir of the gods and demons realm.

This can be regarded as the luck and creation that the night butterfly brought to Lu Feng, and throughout the cultivation world, no living being has it.

"It's kind of interesting. ”

Lu Feng muttered, a chuckle rising at the corner of his mouth.

While recuperating from his injuries, Lu Feng was also contemplating the Great Dao of Enlightenment, and he had a deeper understanding of the Great Dao of Thunder and Fire, and his attainments in the order of the Great Dao could be regarded as having entered the ranks of the peak.

And the deeper the perception of the avenue, the more the mystery of the avenue is yearning, and Lu Feng can't wait to trace the origin of the avenue.

For any practitioner, uncovering the mysteries of the Great Dao is a temptation that cannot be refused.

When Lu Feng was recuperating from his injuries, he could only participate in the Great Dao of Enlightenment, but now that his injuries have healed, he can practice as much as he can and improve his cultivation.

The Burning Immortal Sword floated in the air, and the space around him suddenly distorted, ready to enter the space inside the sword of the Burning Immortal Sword, the cultivation of the Burning Immortal Technique, and the perception of the power of the Fire Dao, there was no place in the cultivation world that could not be compared with the space in the Burning Immortal Sword.

"Are you coming in?" Lu Feng said as he looked at Night Butterfly.

Night Butterfly's beautiful eyes were slightly stunned, the Burning Immortal Sword floated in the air, she guessed that Lu Feng wanted to enter the inner space of the Burning Immortal Sword, but she didn't expect that Lu Feng would invite her to enter together.

"Of course. ”

Night Butterfly said coquettishly, in the world of gods and demons, it is a legendary peerless immortal sword, and she is also very curious about what is mysterious about the space inside the sword.

However, now Night Butterfly no longer has the idea of competing with Lu Feng for the Burning Immortal Sword and the Immortal Sword, but she has a trace of expectation for Lu Feng, and pins her hope of rescuing the Demon Emperor on Lu Feng's body.

The two of them entered the sword space of the Burning Immortal Sword together, and saw the sword spirit, which was full of flames, forming a small world of its own.

With the continuous improvement of Lu Feng's realm and the enhancement of his cultivation, the space inside the sword of the Burning Immortal Sword also changed at the same time, especially after Lu Feng stepped into the Dao Void Realm, the changes were simply earth-shaking.

Compared to when Lu Feng had just stepped into the Dao Void Realm, the sword space of the Burning Immortal Sword became more and more vast and vast, and with the improvement of Lu Feng's realm this time, the space inside the sword had undergone amazing changes.

The ground of the space inside the sword was a sea of fire, and the void was imprinted with mysterious Dao patterns, filled with an incomparably pure fire Dao aura.

At first, the Great Sun Essence Fire was still burning around the two of them, and as Lu Feng and Night Butterfly penetrated deeper into the space inside the sword little by little, the Sun Essence Fire gradually disappeared and was replaced by the Fire of Nirvana.

It's not that the sun essence fire is not strong, the two flames are both shocking divine flames in the world of gods and demons, but the fire of nirvana is more mysterious.

Lu Feng's footsteps stopped, the fire Dao aura in this place was already quite terrifying, and the creatures who had not reached the Dao Void Realm could not stay at all, otherwise they would be incinerated in a moment, and they would be wiped out, and even the divine soul would not be left.

The Nirvana Fire around him was much more powerful than the Nirvana Fire controlled by Lu Feng, and the Dao patterns in the void were mysterious and obscure, extremely difficult to understand, reaching a level that even Lu Feng couldn't understand.

As the realm of Lu Feng increases, the space inside the sword of the Burning Immortal Sword will also change, and these patterns imprinted in the void will also evolve, becoming more and more profound and mysterious.

The flame pattern in the void is more profound than Lu Feng's perception, which is conducive to Lu Feng's observation and comprehension.

"This is the space inside the Burning Immortal Sword. ”

Night Butterfly sighed softly, her pretty face flashed with a touch of shock, she was observing the lines in the void, and a trace of fire aura condensed into flames on her fingertips.

The crimson flame jumped, and the domineering power of the nirvana fire couldn't hurt the night butterfly in the slightest.

The daughter of the Demon Emperor, her bloodline is incomparably noble, and the delicate body of the night butterfly is extraordinary.

"If I'm not mistaken, as you grow, the space inside the two fairy swords is also changing. Nightbutterfly said.

Lu Feng nodded, it can be regarded as a default, this girl was born in the realm of gods and demons, she is talented and intelligent, and her vision is extremely high, and she can see the subtlety of the space inside the Burning Immortal Sword, which does not surprise Lu Feng.

"Feel free to do so. ”

Lu Feng Dao, he sat cross-legged in front of those Dao patterns that imprinted the void, absorbing the incomparably pure Dao aura around him, and the fire of Nirvana was lit all around him.

He grew up in the repeated battles with the demons, his realm was improved, and he had a glimpse of the Divine Phoenix Treasure Technique for the first time, and he used it for the first time, in fact, Lu Feng's perception of the fire of Nirvana was not profound.

The space inside the sword of the Burning Immortal Sword had also just undergone astonishing changes, giving birth to the fire of Nirvana, as well as the mysterious Dao pattern in the void.

Now Lu Feng wants to further comprehend the Divine Phoenix Treasure Technique and spy on the mysteries of the fire of Nirvana.

Lu Feng entered the state of cultivation, his mind was not distracted, and gradually, the majestic fire aura poured into his body, and the fire of Nirvana around his body became more and more intense.

Not long after, Lu Feng's body was transformed into a pair of divine phoenix wings, and the feathers were like red gold, exuding a mysterious and terrifying fluctuation.

His physical body contained Dao, and lines appeared in his body, blooming with red firelight, as if the divine flame was burning.

The lines on the body are changing little by little, this process is very slow, but it is amazing, and it is very mysterious. The evolution of these lines means that the realm of land breeze has been improved, and the understanding of the fire path has been deepened.

It is not difficult to see that the lines on Lu Feng's body are getting closer and closer to the Dao patterns imprinted in the void.

And in Lu Feng's body, every inch of flesh and blood, every bone, and every meridian are being tempered by the fire of Nirvana. The newborn flesh underwent an astonishing metamorphosis, and the flesh of other places became more resilient.

It was as if he had turned into a divine furnace, constantly refining himself, and he could feel the aura emanating from Lu Feng's body, which was improving at a rather astonishing speed.

Rao is like this, his realm is still a long distance away from the completion of the Dao Void Realm, the Dao Void Realm is too vast, and the difference between each small realm is a huge span, and the perception of the power of the Dao is not at the same level at all.

Night Butterfly is also observing the Dao pattern and absorbing the fire of Nirvana into her body, and this kind of divine flame is also of great help to her cultivation.

While she was cultivating, she didn't forget to glance at Lu Feng occasionally, and there was a hint of tenderness in her beautiful eyes, which was the first time in her life.

And on one of the delicate little hands of the night butterfly, an evil demonic fire was ignited, and she was cultivating this demonic fire with the fire of nirvana.

"Wow!"

Suddenly, a loud bird chirp resounded, and the pair of divine phoenix wings behind Lu Feng flapped, the fire spewed thin, and the rune patterns condensed, gradually turning into the body of the divine phoenix!
