As the greatest existence since the beginning of the world, the ancestral dragon was conceived in chaos, and it was the first creature of chaos at the beginning of all things.

The next moment, he saw Yu Duxiu's body transformed for a while, and the next moment his body was thousands of feet, and his body was chaotic and hazy, as if the true body of an ancestral dragon born of chaos appeared in the starry sky.

The scales are ancient and full of great mysteries, and countless mysteries of heaven and earth loom above the scales.

Yu Duxiu's eyes flashed with Dao divine light, not caring about the vision brought by the ancestral dragon's true body, but directly looking inside his own body, if there was really that rune array inside the ancestral dragon's true body, the ancestral dragon took a step, the void seemed to be distorted at this time, the endless starry sky became smaller under the ancestral dragon's grasp, and a star seemed to be a stone, falling at the feet of the ancestral dragon.

Yu Duxiu looked at the runes in the ancestral dragon's true body, but found that the rune array in the ancestral dragon's true body was more ancient than the rune array in the thunder beast's body, and the chaotic qi of the Dao Dao was constantly rising and falling, covering the entire rune array within the rune.

Looking closely at the runes, I found that each rune was vague and invisible, as if hidden in the chaos, and it was difficult to see clearly.

The rune operates, constantly extracting a strange power from the underworld, this power can law the heavens and the earth, can command the world, change the heavens and the earth, the vastness, the vicissitudes of life, the ancient, the supreme, the supreme, it seems that the greatness and supremacy of this power cannot be described.

In the face of this force, Yu Duxiu's whirling creation is running rapidly, constantly absorbing this power, and it is better to say that it is appropriate to absorb it.

This force is too powerful, even if Yu Duxiu can seize the power of heaven and earth, he seems to be powerless in the face of this power.

It's not that the supreme supernatural powers of the Taoists in the previous life can't work, but that Yu Duxiu's cultivation is not enough, and he can't push the Xuan Xuan Creation to the peak.

Yu Duxiu carefully comprehended this big array. After a long time, Yu Duxiu's eyes lit up, and he suddenly accepted the true body of the ancestral dragon, and his physical body stood on top of a star.

"I refined the true blood of the ancestral dragon into the spine dragon, this rune array is too complicated, it is not something I can comprehend at all, if you want to comprehend the law of heaven and earth, you need to start with the spine dragon" Yu Duxiu slowly closed his eyes, and the Yuan Shen shuttled through his body, reflecting the spine above.

Jade Duxiu's spine is as white as jade, flashing with crystal light. There is a feeling of mutton fat and jade, and if you look closely at the spine dragon, it seems to be like a divine dragon, lying in the body of Yu Duxiu.

As soon as his mind moved, he constantly felt his spine, and the joints and bones above the spine were connected together in a mysterious law.

"There is no mystery outside the spine, that is, inside the spinal cord" Yu Duxiu slowly penetrated the Yuan Shen into the spinal cord, which is the key to human beings and the source of strength. The essence of the bones as a foundation.

Yu Duxiu Yuan Shen infiltrated into the spinal cord, and the next moment it seemed to have come to a blood-colored world, and the bright red blood rolled among the bones, wrong. It should be a peristalsis, and the bone marrow is about to turn into a substance, and in this bone marrow, the chaotic qi of the Dao Dao falls. It seems that this bone marrow contains a chaotic world, and even the primordial god of Yu Duxiu is difficult to see everything in the chaos.

But the next moment, Yu Duxiu's eyes lit up. He saw a familiar rune array.

"Found it, it's you" Yu Duxiu's eyes lit up, and the Yuan Shen hurriedly came to the rune array.

It's a pity that the rune array was covered by the chaotic qi, and the fog was hazy, and Yu Duxiu couldn't see it at all.

"How should this be good" Yu Duxiu scratched his ears and cheeks a little, obviously Baoshan was in front of him, but he was guarding Baoshan and wanted to beg for food.

"The true blood of the ancestral dragon has been refined into the bone marrow by me, this bone marrow is my bone marrow, and it should be ordered by me" Yu Duxiu Yuan Shen returned to his senses and slowly opened his eyes: "I have already sacrificed the bones, then I am sacrificing the bone marrow."

Saying that, Yu Duxiu began to use the inner fist to constantly wash and shake the bones, although Yu Duxiu couldn't control the rune array in the bone marrow, he could control the bone marrow.

Let the bones absorb the bone marrow, if the rune array is fortunate enough to be absorbed by the spine, then he can urge the spine to exert the power of the law heaven and earth.

The power of the endless stars swept from the void and turned into mist around Yu Duxiu's body, which was continuously absorbed.

This starry sky is good, Yu Duxiu constantly uses the power of the stars to quench the body, refine the spine, and cultivate the bone marrow.

Neijiaquan first cultivates the membrane, then cultivates the muscles and bones, and finally the spine and spinal cord, and then practices the whole body and begins to exchange blood.

Since coming to this world, with mana and supernatural powers, Yu Duxiu has cultivated a lot less of inner boxing, just as a technique to strengthen the body and refine the body, but he has not let it go.

With such a strong power of the stars, coupled with Yu Duxiu's cultivation into a primordial god, his body is meticulous, and he knows every move of his body well, but it is only three months, and Yu Duxiu's bone marrow has begun to change and be refined.

Yu Duxiu jumped between the stars, while absorbing the power of the stars, refining the bone marrow, anyway, the last thing he lacks is time, there are still hundreds of years to live, Yu Duxiu is not in a hurry to make a breakthrough.

A year later, Yu Duxiu didn't know how many stars he had jumped, and he didn't know how far away he was from the desolate land, and there was only one outline left in the desolate land at a glance.

On this day, Yu Duxiu was standing on a star, constantly absorbing the power of the stars that connected the heavens, and suddenly the bones were hot, and the scorching power burst out along the bones towards the bone marrow, and the breath spread all over the body.

"Roar" A slight roar echoed in the void, this sound was not Yu Duxiu's, but came from the spine in the body, at this time the spine changed, and it really turned into an ancestral dragon covered with ancient scales, and even Yu Duxiu could sense through the spine that various organs had begun to derive from the spine, yes, it was an organ belonging to the Chaos Ancestral Dragon.

Yu Duxiu finally really absorbed the ancestral dragon essence blood, and in the future, there will only be Yu Duxiu's spine ancestral dragon, and there will be no ancestral dragon essence blood.

What is Ancestral Dragon Essence Blood?

That is a real treasure of heaven and earth, blood rebirth is just idle, coupled with Yu Duxiu's cultivation and transformation, as well as the transformation of the ancestral dragon, the spine behind this Yu Duxiu actually turned into an ancestral dragon, a young ancestral dragon, countless chaotic qi surrounded the ancestral dragon, and then converged into silence.

Yu Duxiu's thoughts, but saw that the ancestral dragon that exuded endless majesty slowly transformed, and once again turned into a crystal like jade spine, on which spine, countless complex runes were imprinted on it, there were those that Yu Duxiu had seen, and those that Yu Duxiu had never seen, all of them were the ancestral dragon inheritance left in the essence blood of the ancestral dragon.

It can be said that if Yu Duxiu dies one day, this spine may really be able to turn into an ancestral dragon and soar into the world.

Among the countless lines, Yu Duxiu saw the rune array he most wanted to see, which contained the twenty-four joints of the entire spine, uniting the twenty-four joints together.

A wonderful feeling came into Yu Duxiu's Yuan Shen, and the next moment Yu Duxiu's palm stretched out, the void was shaking, gently urging the rune array on the spine, the formation was running on the spine, and a force was drawn from the endless void in the underworld, Yu Duxiu underwent a mysterious change at this time, obviously the body did not become larger, but at this time, it seemed to have become the center of this piece of air, a giant in this piece of starry sky, and everything was subordinated to its feet.

This is a very strange feeling, Yu Duxiu is so small compared to the stars, but at this time, Yu Duxiu feels that this piece of starry sky is crawling under his feet, and the starry sky is not far away, just a few steps away.

However, Yu Duxiu felt that his spine was trembling, as if he was breathing, continuously absorbing Yu Duxiu's mana and the power of the stars between heaven and earth.

"Mana consumption is so fast" Feeling the speed of mana consumption, Yu Duxiu suddenly changed color, and urged this rune array by himself, but he could only hold on to half a pillar of incense for a long time, and then the mana consumption was wiped out.

"No" Yu Duxiu hurriedly stopped his own indoctrination, looking at the mana that consumed a lot, Yu Duxiu showed a wry smile: "Consuming so much mana, if you fight with others in the future, unless you can fight quickly, you can only be slaughtered by others." (To be continued.) )
