The source of the longevity recipe is mysterious, one is the legend that it was passed down by Guangchengzi, the teacher of the ancient Holy Emperor Xuanyuan Yellow Emperor, and the other is that it is said to be received by a plain girl.

In fact, although Xia Fan was a little curious about who left the longevity recipe, he was just a little curious.

After the world of Zhilu Dao was transformed by a supreme treasure, he knew that everything in the Dao Illusory Martial Realm, whether it was a country or a martial arts world, was just a conjure.

The shattered reincarnation of the world realm once in a hundred years is enough to explain all this, so it is naturally meaningless to investigate who left the secret of immortality.

However, it is impossible for the peerless exercises conjured up by the Supreme Treasure to be meaningless, what is the Supreme Treasure, that is, the spiritual treasure condensed by the laws of heaven and earth.

Therefore, although everything within the Phantom Martial Realm is transformed, it is true and reliable, and the longevity recipe of the Four Great Wonder Books naturally has its own reason for existence.

"It's worthy of the Four Great Wonder Books, and even I can't destroy this paper in the slightest!" Xia Fan tried to tear the book in his hand, and his curiosity increased again.

"I don't know these words, but now I don't even know them, it's not an oracle bone inscription, it's not Zhong Dingwen, and I don't know when it's a text in ancient times, and I don't have any sense when I look at these pictures" Xia Fan muttered to himself with a headache:

"Well, it shouldn't be, Ssangyong can sense two exercise diagrams, but I can't comprehend one, is my qualification and comprehension so poor?"

"Yes, if it is really a practice handed down from the fairy world, according to the conclusion in the novel in the previous life, it should be watched with the power of the divine soul, I will try it!"

After thinking about it, Xia Fan put this thin book of cheats tightly in the middle of his forehead.

Since Xia Fan entered the Phantom Martial Arts Realm, all the strength of his body has been suppressed, and his divine soul and yuan power have been imprisoned in his body, and he cannot use half of it without his body.

However, this did not stop Xia Fan's exploration of the longevity formula, the power of the divine soul could not be separated from the body, but it could flow on the surface of the body, and the middle of the forehead was where the heavenly court of the human body was located, and it was also the location of the upper dantian, which was closest to the sea of knowledge.

Xia Fan placed the secret book in the middle of his forehead, and the spirit in his body came into contact with the secret book, and the longevity recipe suddenly changed, blooming with a brilliant and colorful light.

It was a dark void, with no sunlight or stars in the entire space, except for seven large images of seven different lights floating in a circle.

At this time, Xia Fan's soul was separated from his body, and he was in the middle of those seven images, and he could hardly feel where his physical body was.

However, despite the sudden mutation, Xia Fan did not have any panic, he knew very well that this dark void, or the seven images in the void, was the true secret of the Immortal Formula.

At this time, Xia Fan once again 'looked' at these seven huge images, but he could already clearly understand the true meaning of them, and countless mysteries flowed into Xia Fan's soul from the seven images.

"Good thing, this longevity recipe is really a good thing!" After seeing the true meaning of the longevity formula, Xia Fan was ecstatic in his heart.

The recipe for longevity is indeed passed down by Guangchengzi, the teacher of the Yellow Emperor, and is different from ordinary practice exercises, which is the practice of the five elements of yin and yang, and has the spiritual effect of cultivating the essence of the five elements of yin and yang, and strengthening the meridians of the internal organs.

Although the path of cultivation is more important than the foundation, and although the foundation is still extremely difficult and there are many obstacles, it has laid a solid foundation for the Babel Tower.

And the recipe for longevity is an exercise created for this cornerstone, and to put it bluntly, the recipe for longevity is actually a basic practice on the path of longevity.

However, in Xia Fan's opinion, this basic technique was extremely precious, more precious than any Qi refining secret book he had encountered.

Although Xia Fan's jade refining recipe fuses the five elements and six combined fists, although it can refine the five internal organs and strengthen the five internal organs, it is really a little insufficient compared to the jade refining recipe's request for the essence of the five elements.

Now, the Five Elements and Liuhe Fist has become one of the shortcomings that restricts Xia Fan's advancement to the peak of the Transformation Realm.

Now, with the mutual integration and promotion of the longevity recipe and the Five Elements Liuhe Fist, the essence of the Yin and Yang Five Elements in Xia Fan's body will inevitably increase greatly, which not only meets Xia Fan's advanced needs, but also has an excellent effect on Xia Fan's Five Elements Mystery Evolution Five Elements Divine Power.

After half a ring, Xia Fan took the secret book of the longevity recipe from his forehead, and at this time, the true meaning of all the contents of the longevity recipe had been fully integrated into the depths of Xia Fan's soul, and he did not worry about losing it.

"Shuanglong holds such a treasure in his hand, but he can only get one of them, it's really speechless!" Xia Fan smiled to himself: "However, in this Phantom Martial Realm, except for a very few people who have the secret method of cultivating the spirit, it is not surprising that no one else cultivates the divine soul, and no one can discover the true meaning of the Immortal Formula." ”

"It's that Shuanglong can get one of the seven exercises from the longevity recipe when he is at the end of the year, and he is worthy of being the protagonist of luck!"

The secret of immortality has already been seen, and he has also understood the mystery in it, and now all Xia Fan has to do is to find several other strange books.

Among the four strange books, the Cihang Sword Book can be said to be the only strange book that does not have the legend of the broken void, and all the warriors who practice the Cihang Sword Book are rare to have a good death, and the best ending is to die in silence.

And Cihang Sword Code is Cihang Jingzhai's Zhenfang Sect Exercise, not to mention whether these fake nuns are willing to give the Sword Book to Xia Fan to see, even if they are willing, Xia Fan may not be willing to watch this strange book.

As the first of the four strange books, the God of War Catalogue is even more difficult to obtain, and the space in which it is located is not fixed, it seems to be an independent different space, and the time of opening is uncertain.

Originally, in the Ming Dynasty, there was also the Han family lineage that also had the imprint of the God of War catalog, that is, the memory of the heroes who passed on the eagle in the eagle knife.

But it's a pity that the Han family has had no news on the rivers and lakes since Han Bai went into hiding, and even with the vast supernatural powers of the Sun Moon Divine Sect, they can't find their traces.

Therefore, it is impossible to get the God of War Catalogue in a short period of time, so the only thing that can attract Xia Fan in Datang now is the Heavenly Demon Strategy.

There are a total of 12 volumes of the Heavenly Demon Strategy, after hundreds of years of war and contention, resulting in the dispersion and loss of the Heavenly Demon Strategy, to the Tang Dynasty when only six volumes of the twelve volumes remained, which is the inheritance of the ten sects of the Demon Gate.

And there are actually only two volumes that really attract Xia Fan in this Heavenly Demon Strategy, namely the two volumes of Dao Heart Demon Cultivation Dafa and Heavenly Demon Secret.

The Dao Heart Demon Dafa is of great help to Xia Fan to improve the battle type, Xia Fan knows that the war type is just created by him out of thin air, and there is no experience reference from his predecessors, and it is not perfect.

In fact, those who accept the war type have great restrictions, and they must have an extremely strong physical body, otherwise they will explode and die because they cannot withstand the violent battle qi source power of the war type, which is the imperfection of the war class.

And the magic trick in the Dao Heart Demon Cultivation Dafa also has a similar way to the battle seed, but the effect and result are different, but the magic trick is more perfect to the fullest, and the demon seed can be planted silently without the recipient noticing.

If the method of cultivating demons and cultivating demons is added to the types of war, Xia Fan believes that it is completely possible to improve the types of wars and reduce the restrictions on the conditions for accepting types of wars.

In Xia Fan's view, the role of the Heavenly Demon Secret is nothing more than the use of true qi, and the use of the Heavenly Demon Secret of true qi can be completely unpredictable and unpredictable, so that Xia Fan can be of great help to the use of his own strength.

·····

Xia Fan's battle in the martial arts dojo of Chang'an City had already spread all over the Tang Dynasty, and the righteous martial arts had lost such a big face, and the demon dao was not only gloating, but also secretly sad.

Because Xia Fan said that he wanted to watch the four strange books.

If someone said this half a year ago, the entire Datang Demon Dao could spit and spray this person to death.

But now that the door-smashing kid said so, the Ten Demon Dao Sects could only pinch their noses and dedicate the only six remaining volumes of the Heavenly Demon Strategy.

Twenty years after the founding of the Tang Dynasty, Shuanglong's strength has surpassed the three great masters of the past, whether it is in the right path or the demon path, Shuanglong has become the uncrowned king of the Tang Dynasty.

Now, even Kou Zhong admits that he is not the opponent of this door-smashing kid, and the demonic path of believing in the strong will definitely not go against Xia Fan's wishes.
