After entering the Earth Milk Yuan Pool, the pores around Yingyi's body suddenly opened, and the three hundred and sixty-five acupuncture points were like the eyes of the wind, and countless small snake-like vitality kept burrowing into the flesh and blood of the meridians.

After these core stone milks entered Ying Yi's body, the furnace virtual image in the star core began to rotate at a far more extraordinary speed as if it smelled its prey, like a black hole, constantly devouring all the stone milk vitality, and then transformed into incomparably pure heaven and earth vitality.

The Taiyin Star Core also began to become unusual, the power of the ancient demons that could not be refined for a long time, under the power of the powerful oven, almost without much resistance, had already been annihilated into nothingness, and sprinkled down with the monstrous rain tide of vitality.

The calm sea of Yuan Qi began to boil non-stop, and even began to become hot, and Yingyi's own Taiyin True Qi began to have some kind of unusual fusion with these Heaven and Earth Yuan Qi, which was a change that would only occur when a cultivator broke through the Rong Yuan Realm.

Without the slightest resistance, and without the slightest accident, the sea of true qi that was originally in the shape of a mist began to become extremely compressed, and the first drop of true yuan began to be born in the core of the Taiyin star, which was even darker than ink.

With the birth of this first drop of true element, an extremely terrifying devouring force was generated in the Taiyin star core, and a tornado pillar connecting heaven and earth appeared inside the star core, and the infinite heaven and earth vitality began to be attracted, making this wind pillar more condensed.

Around the pillar of wind, a black rain began to fall, this is a rain in the true sense, covering almost the entire internal space of the star core, this rain that seems to have no root, but it is the true yuan power formed by the fusion of countless heaven and earth vitality and Taiyin true qi.

Breaking through the realm of fusion yuan, can transform the true qi into a more powerful true element, but the core stone milk is another form of heaven and earth vitality, Ying Yi did not open the layer of separation between the body and heaven and earth but can give birth to the true yuan power, although he did not really break through the realm, but from the first drop of true yuan appeared in the Taiyin star core, he was already a real Rong Yuan realm cultivator.

As the rain became more and more rainy, a shallow pool of water had begun to accumulate inside the galaxy, and it continued to expand, even if ordinary cultivators fused the Heaven and Earth Yuan Qi, the number of True Yuan in their bodies would not be very large, and the fusion of Heaven and Earth Yuan Qi was an extremely slow process.

A cultivator has just broken through the Fusion Yuan Realm, and the body still needs a process of adaptation to the Heaven and Earth Yuan Qi, which is also the first step for a cultivator to truly transform into an ordinary person, and he always needs to be much more cautious.

The process of transforming the body's true qi into the true yuan is the lower realm of the fusion yuan in the cultivation realm, and this time is the process in which the cultivator himself begins to slowly adapt to the heaven and earth yuanqi, and only after the body truly adapts to this heaven and earth power, can the cultivator use the power of the heaven and earth yuan qi in battle.

It's just that Ying Yi doesn't need to go through this process, his flesh and blood have the power of gluttonous natal powers, and the power of the furnace devours the earth's core stone milk to transform it into pure vitality, and suppresses these vitality and begins to merge with his own true qi, which is many times easier than ordinary cultivators.

After the cultivators broke through the Rongyuan Realm, if they wanted to convert all the true qi in their bodies into true yuan, they would need to spend several years of hard work, and they would have to spend more time to accumulate the power of the true yuan.

With the passage of time, a full feeling was transmitted from the star core to the brain, and Ying Yi knew that the true yuan power in the Taiyin star core also began to become saturated, and at this time, the furnace phantom suppressed inside the star core also became stable, and the Taiyin true qi that was originally like a sea of mist all disappeared, turning into a more condensed and powerful Taiyin true element, almost more than ten times more than ten times more than the cultivators of the upper realm of the Rong Yuan.

Losing the devouring power of the oven, the core stone milk that poured into the body began to melt into and penetrate into every trace of flesh and bones, and every inch of the muscles and bones were glowing with a more red luster.

Click......

A faint sound of bones breaking came from the body, and the originally calm face suddenly became extremely hideous, and the face was even crisscrossed by excessive distortion.

Ying Yi groaned hoarsely in pain, like the faint roar of a young beast, and blue veins erupted on his forehead, and he could see that something was surging inside.

The tiny stone milk vitality that flowed into his body gnawed at his bones, blood, tendons and veins like countless silkworms, and there was a rustling sound in his body, as well as many friction sounds made out of nowhere.

The most powerful thing for a cultivator is the true yuan power, and in the practice of not working day and night, the essence and blood in their bodies are also unusually nourished by the vitality energy, perhaps the blood qi power is also an important source of strength for the cultivator.

Therefore, many cultivators will consciously use these heaven and earth vitality to refine the bone marrow in addition to channeling the essence and blood in the body, which is not weaker than the true element, which is also the reason why the cultivator's body is far stronger than that of ordinary people.

Ordinary people have only a few drops of essence and blood in their bodies in their lives, and their bone marrow is fixed at birth, and if they don't practice, they are afraid that they will die the same as when they were first born.

And cultivators can use rare medicines and heaven and earth vitality to nourish their bone marrow, causing incredible changes in their bone marrow, causing their body essence and blood to be dozens or even hundreds of times more than that of ordinary people.

These stone milk vitality that resembles a small silkworm is precisely in Yingyi's body to refine his bone marrow, and the huge vitality is compressed into the bone marrow, and some impurities in the original bone marrow are naturally cleaned out, which is like a knife scraping back and forth inside the bone marrow, which is more painful than cutting bones and meat, which is also the reason why his face has become hideous, such pain is difficult for ordinary people to bear.

The impurities inside the bone marrow are crushed into tiny particles that cannot be seen at all under the tempering of the vitality, and are finally removed with the body's metabolism.

Yingyi's forehead and body were covered with sweat, and at first it was still transparent and watery, but soon it had turned reddish-brown, like the color of blood, perhaps this was simply blood oozing from pores.

It didn't take long for him to become a bloody man, and his body was covered with a thick layer of blood scabs, but his original face was not clear to see.

Although he experienced extreme pain, Yingyi's consciousness was still clear, and he deliberately guided him to use the power of the earth's core stone milk to refine his own bone marrow.

Cultivators of the Rong Yuan Realm, if they want to better integrate their bodies with heaven and earth, they naturally need their own physique to be pure enough, and the first two realms of cultivation are just a little stronger than mortals, but after all, they will inevitably eat grains, and they will naturally accumulate a large amount of poison of grains.

Therefore, the cultivators of the third realm have consciously begun to cleanse the body of the poison of the five grains, and only in this way can the body become more pure, better and greater to integrate the vitality of heaven and earth, and this process is called "washing the marrow" by the practitioners.

Win Yi now wants to use the power of the earth's core stone milk to completely remove the poison of the five grains in the body and complete the extremely critical level on the path of cultivation.

As time passed, the blood scabs on Ying Yi's body surface accumulated thicker and thicker, and his body was already wrapped in thick black-brown blood scabs, but the aura he exuded became deeper and deeper, and there was a hint of indifference in the sky and a sea of clouds.

At this time, major changes also occurred in his body, and the bone marrow, which was originally a little variegated, had become as white as jade, whiter than the hoarfrost in the cold of winter.

More of the stone milk energy penetrates into the bone marrow, and the new bone marrow also begins to produce the first drop of blood, and the blood, which is more red than the ruby gemstone, is born from the bone marrow, enters the blood vessels that have already dried up, and begins to spread to all parts of the body.

Like a trickle, more blood began to flow all over the body, redder and thicker than before.

The blood vessels in Yingyi's body are as crystal clear as jade, and you can also see that the blood and qi in it are like clusters of flames, which are penetrating into every inch of skin to nourish and feed back to his body, and his flesh and blood fascia have begun to shrink tightly, becoming more dense.

The blood scab on the original body surface fell off in large chunks, revealing the bronzed skin inside, and it could be clearly seen that it was brighter and more condensed than just now.

Ying Yi suddenly opened his eyes, and a touch of essence came out of his eyes, with irrepressible excitement.

Feeling the slowly surging plasma in the body, it became as heavy as mercury, and even the whole person's body became much heavier because of this, and a trace of realization flashed in Yingyi's heart.

"Refining the marrow into frost, refining blood mercury slurry!"

With the help of the huge vitality of the Earth's Core Stone Milk, Yingyi truly succeeded in cleansing the marrow, and his physical fitness was many times stronger than before, reaching the physical realm that many Fusion Yuan Realm cultivators failed to reach.

If a cultivator wants to cultivate the bone marrow and blood qi to such a realm, it is far more difficult than cultivating to the True Meditation Realm, because the Yuan Qi power required during this period may not be able to accumulate enough even for cultivators in the Upper Realm of Fusion Yuan, and only a cultivator in the True Meditation Realm can control a large amount of Heaven and Earth Yuan Qi in order to truly complete this physical transformation.

It can be said that with the help of the huge vitality of the earth's core stone milk, Ying Yi has already walked in front of the vast majority of Fusion Yuan cultivators, and it doesn't take much time to break through to the realm before the True Observation Realm, and he has already completed the accumulation of the vast majority of Fusion Yuan cultivators at this time.
