There is a legend about the Thunder Emperor, and the knowledge of the Sword Spirit of the Immortal Sword is also very limited, and there is only so much information that the Sword Spirit can pass on to Lu Feng.

And the Thunder Emperor's Treasure Technique, known as the strongest mystery of the Thunder Dao, can be imagined how terrifying it is.

It's a pity that after the tragic death of the Thunder Emperor, the Thunder Emperor's Treasure Technique has not been completely inherited, and the Thunder Emperor's Treasure Technique contained in the Immortal Tribulation Recipe is also incomplete.

However, even the crippled Thunder Emperor's Treasure Technique was enough to shock the world.

"It's actually the Thunder Emperor's Treasure Technique!"

Night Butterfly's beautiful eyes were startled, and her delicate red lips let out a slight shocking sound.

She knew that the seven immortal swords all contained the treasure techniques of powerful pure-blooded beings in the god and demon realm, and she had already seen Lu Feng perform the treasure techniques of the three major creatures of the Golden Crow, the Fox and the Divine Phoenix, and she also thought that the treasure art of the Immortal Sword would be passed on to Lu Feng, but she didn't expect that it would be the Thunder Emperor's Treasure Technique!

It was an ancient god emperor, even in the demon world, a terrifying existence known to all demons, even if he died for endless years, he still left rumors that shocked countless living beings.

If it was in the realm of gods and demons, even if only the news of the Thunder Emperor's treasure came out, it would alarm the gods and demons of the heavens.

The head of the Thunder Emperor Dragon, in front of Lu Feng, the phantom of the Thunder Emperor is very blurry, and the runes on it are as simple as possible, so that it will become like this, and it is easy for Lu Feng to understand.

A mysterious pattern appeared in Lu Feng's body, as if thunder had descended from the sky, quenching on Lu Feng's flesh and blood, robbing the light and rolling thunder, as if he was under divine punishment.

A mighty coercion spread out in this space, containing the will of heaven and earth, and even the night butterfly trembled.

Lu Feng fell into a state of cultivation without distractions, his mind was ethereal, and he was integrated with the thunder path, as if he was a thunderbolt, representing the will of God.

This state of cultivation alone has made many powerhouses in the cultivation world who have comprehended the Thunder Dao beyond their reach, surpassing them too much.

It is too difficult to integrate with the Great Dao, not only to have a very high realm, but also to have a very deep understanding of the Great Dao, but also to fit the body and the Great Dao perfectly, which is too difficult, even in the Demon Domain, many of the great demons of the Dao Realm have a natural advantage compared with human warriors, and there are very few big demons who can achieve a perfect fit between the physical body and the Great Dao.

However, Lu Feng did it, he was reborn in the human realm, and he broke through all the way to the cultivation realm, and the transformation of his physical body was even more amazing than the improvement of his own realm and strength.

Rumble......

Above the sky, thunder flashed, thunder exploded, and thunder descended and fell on Lu Feng's body.

Thunder fire is the most effective for refining the physical body of living beings, especially the thunder that represents the will of the heavens.

The transformation of the physical body is endless, Lu Feng's physical body looks at the cultivation world, if it is called second, I am afraid that no living being can be called first.

Compared with his previous life, Lu Feng's vision is higher, at the beginning, Lu Feng's goal was to find Mo Duxing for revenge and regain some of his losses, but at this time, killing Mo Duxing was no longer his ultimate goal, he longed for the upper realm more.

In the cultivation world, there were originally many rumors about the wasteland, and in the process of cultivation, the two sword spirits told Lu Feng little by little about the vastness and mystery of the gods and demons, and the contact with the night butterfly made Lu Feng yearn for the gods and demons world even more.

Ascending to the Wasteland Realm is not Lu Feng's goal, one day he will set foot in the Realm of Gods and Demons and stand among the gods and demons of the heavens.

Therefore, Lu Feng's refining of his physical body cannot be judged by the eyes of the beings in the cultivation realm, his physical body is not perfect enough, he must demand himself by the standards of the genius beings in the upper realm.

He stayed in the sword space of the Immortal Sword for a longer time, the Thunder Emperor's treasure technique was too mysterious and mysterious, even if it was only a fragment, the lines engraved on the Thunder Emperor's phantom were as simple and easy to understand as possible, but it was still extremely difficult for Lu Feng to comprehend.

Unconsciously, Lu Feng had been staying in the Immortal Sword for more than a month, and his figure was sitting in the void, motionless, his brows furrowed.

The more anxious he is, the more he can't comprehend it, Lu Feng knows this very well, he is as calm as ever, his heart is like an ancient well, and there is no trace of waves.

Gradually, Lu Feng began to have a little bit of enlightenment, and he found a breakthrough in the comprehension of the Thunder Emperor's Treasure Technique, as if he had pierced the barrier at once.

From this moment on, it became different, and he had a clear understanding and gradually spied on the mystery of the Thunder Emperor's treasure art.

The Dao pattern on Lu Feng's body changed, and he was deducing the Dao pattern, exuding an inexplicable Dao rhyme all over his body.

The Thunder Emperor's phantom gradually became clearer, and he comprehended the Thunder Emperor's Treasure Technique!

However, at this time, the sigil of the three-eyed golden-eyed ape was transmitted, interrupting Lu Feng's cultivation.

"The major strengths of the Killer Dynasty and the Warrior World have been killed to the depths of the Demon Domain, and the demons are defeated and unstoppable, and it won't be long before they will be killed in the Chaos Demon Domain......"

Lu Feng frowned, he was comprehending the Thunder Emperor's Treasure Technique, and he had a first glimpse of the mystery of the Thunder Emperor's Treasure Technique, and entered a state of epiphany.

An opportunity for an epiphany like this is not something that can be met at any time, timing and luck are indispensable, and Lu Feng lost an excellent opportunity to comprehend the Thunder Emperor's treasure art.

However, he also couldn't complain about the three-eyed golden-eyed ape, how could the latter know that Lu Feng was in a state of epiphany, and if it wasn't for an emergency, the three-eyed golden-eyed ape would not easily use the rune to communicate.

Lu Feng stood up, once the state of epiphany was planned, it would be difficult to enter again, and Lu Feng could only give up and stop his practice.

"What happened?"

Night Butterfly asked, she saw with her own eyes that Lu Feng had entered a state of epiphany, and the Dao patterns on his body were changing, but he suddenly stopped cultivating, something big must have happened and interrupted Lu Feng.

"It's a bit of a hassle. ”

Lu Feng said lightly, the depression and unhappiness in his eyes were swept away, he was a person who could afford to let go, and he was interrupted when he entered the state of epiphany, it was indeed a pity, but it was not enough to make Lu Feng's mood fluctuate too much because of this, and next time he would find an opportunity to comprehend the Thunder Emperor's Treasure Technique.

The three-eyed golden-eyed ape sent a message to Lu Feng that the major forces of the Killer Dynasty and the Warrior World were about to enter the Chaos Demon Domain, and the Chaos Demon Domain was not far from the core of the Demon Domain, and it would not be long before they would set foot on this soil.

The demons were defeated and unstoppable, this is a conceivable result, the big clans of the demon domain, such as the True Dragon Clan, the Three Tiger Clans, the Fire Phoenix Clan, the Howling Moon Heavenly Wolf, the Imperial Sacred Lion, etc., have not been dispatched, how can they be able to block the attack of the Killer Dynasty and many big forces.

The three-eyed golden-eyed ape had already taken the big demon under his command to the core of the demon domain and asked Lu Feng about his current location.

"Nine Shadows Palace!" Lu Feng replied, sending a message to the three-eyed golden-eyed ape with a sigil
