The yuan tire was constantly beating, emitting a peculiar vibration.

Affected by the yuan fetus, the qi and blood, bones, and muscles are all shaking in a subtle way.

From the outside world, Song Yifei's originally normal face suddenly turned red, scarlet, as if it was about to drip blood, and then suddenly turned white, like high-quality rice paper, transparent and bright.

If you take off your clothes and look at it, you will find that dense red blood has appeared on his body, like the veins of a big tree with intertwined roots, extracting all the qi, blood and energy from all parts of his body and gathering them into the dantian.

This is the last and most difficult level.

The speed of blood and qi fusion must be fast, otherwise before it is completely integrated, the body will be exhausted and die because of the passage of a large amount of blood and qi.

Whoa!

The dantian has already turned into a sea of blood, and the true qi yuan fetus is wrapped in it, giving birth to silk threads, which are linked to each other, like a spring cocoon that has turned into a butterfly.

The blood and qi continue to integrate, and the yuan fetus gradually has an extra breath of life, just like coming to life, with life, flesh and blood, and a touch of texture.

Outside, Song Yifei's body, because of the passage of a large amount of blood and qi essence, was like a moist earth, drained of water and began to dry up.

Originally, his body had been refined by many cultivations and improvements, and although his actual age was thirty-five years old, he looked like he was only twenty-seven or eighteen.

At this time, he lost the essence of blood and qi, and in an instant, he was dozens of years old, and his twilight was heavy, like a fire candle in the wind, which was about to be extinguished in the next moment.

The skin was dry and crumpled on top of each other, like ill-fitting skin. The hair lost its lustre, like the withered grass of autumn, only to be burned to ashes by thunder. The strong body, shrunk together, is rickety, like an old man who is about to die.

Time passed slowly, Song Yifei's body was like a dried hairtail, smoked bacon, and all the blood and qi were gone, leaving only a little faint vitality like fireflies, barely supporting it.

At this time, a three-year-old child can easily beat him to death!

"Hurry, hurry, hurry!"

Feeling the hollowed-out body, Song Yifei was anxious in his heart, and the incomparable sword intent continued to strangle, because of the infinite illusion brought about by the fusion of the three.

Joy, anger, sorrow, thought, sadness, fear, and shock.

Lust, appearance, prestige, speech, sound, slippery, and human desire.

The body's instinct to face death constantly derives all kinds of desires to pull back the lost flesh.

This is the battle between Song Yifei's consciousness and body, the battle between desire and reason.

Without sword intent, he could be devoured by physical desires at any time and terminate the fusion.

It's like a person who is so hungry that he can swallow anything.

I don't know how long it has been!

In an instant, it's still a hundred years!

Finally, the sky is clear and the moon is clear, and the mind is clear!

Laugh at!

In the dantian, all the qi and blood are integrated, as if it is a mountain of flames, and someone has poured monstrous fire oil out of thin air.

The Yuan Fetus suddenly rose into a dark flame, flowing from the illusory, turning into a clear crystal, bursting out with a brilliant essence light, illuminating the entire dantian.

"It's done!"

Feeling that the Yuan Fetus was completely condensed and successful, Song Yifei was overjoyed.

Throughout the ages, he has intercepted countless Tianjiao Heavenly Moats, and so far he has completely passed! Song Yifei has successfully advanced to the realm of the Grandmaster, and from then on, the sea and the sky will be wide!

At this moment, the waves in a radius of hundreds of zhang were still, and an invisible thought oppression, in an instant, the tide of the sea was surging and spreading, sweeping across the radius, all things bowed down, and all living beings were together!

"Back to basics!"

Now that the fusion was completed, Song Yifei didn't dare to delay, and inhaled violently, the Yuan Fetus jumped for a while, and the True Qi Tornado was blown in the dantian space, like a black glazed Yuan Fetus, which suddenly transformed into blood, like a dragon spitting water, differentiating into a blood-colored torrent, and rushing to all parts of the body.

Thundered!

The fire of life, the fire of boiling oil, suddenly expands, and burns violently.

Cracking sound!

There was a thunderous explosion sound everywhere in his body, and his body swelled violently, like a bulging ball, and there seemed to be a vast force erupting inside the ball, wanting to break the ball!

Every bone, every joint, every muscle vibrates, and the sound of firecrackers resounds. His body was blown up like a balloon and grew taller out of thin air.

The essence is refluxed, and the deficiency is not replenished.

"Lian!"

In the face of this strange situation, Song Yifei did not panic, and urged it to an unprecedented peak, and his true qi continued to be instilled into the depleted flesh, bones, and tendons.

Whew!

With the operation of the breath, Song Yifei closed the acupoints, and between one breath and one inhalation, the body that expanded to the limit began to contract slowly, and the flesh, internal organs, meridians, and bones continued to merge into it with the blood and qi.

Just as iron ore has been beaten and tempered in thousands of ways, it has become stronger and stronger, and it has become a hundred forged steel.

Soon after, the body returned to normal size, and the acupoints around the body were opened one by one, turning into black hole vortices that could not be observed by the naked eye, constantly extracting the vitality of heaven and earth, replenishing the consumption of the yuan fetus.

The power is endless and never exhausted.

With the support of endless vitality, the flesh and blood meridians, internal organs, skin and hair, are reborn.

Whether it is sensory function or vitality, all of them have reached an inhuman state.

The dry hair fell off at all and regrew long, black, thick, wire-solid hair. It grew until it was shoulder-high before it was controlled by Song Yifei and stopped.

The skin has long since become crystalline, fair, smooth, and flawless, like the best mutton fat white jade.

Judging from his appearance, Song Yifei at this time was similar to the original only five or six points, eliminating his mature and masculine majesty, and becoming delicate and handsome, like a beautiful young man who was not stained with dust.

The whole human body seems to be a perfect treasure created by heaven and earth, and it is completely cast according to the golden ratio.

At this moment, the world in Song Yifei's eyes has completely changed.

In the body, the power is like a volcanic eruption, completely beginning to riot, boiling, and constantly climbing.

True Qi returned to the body, and Song Yifei once again felt the strength of the Grandmaster Realm, and the five senses and spirit had all been drastically improved, ten times or even a hundred times surpassing the past.

At the same time, he also experienced every trick in himself, even the rhythm of cells, the feeling of being completely in control for the first time in his body.

The tissues of the body, the muscle cells, and the true qi of the Northern Darkness have all undergone a metamorphosis, and their quality and strength are far greater than before.

Essence, qi, and spirit, the three are one, and they are converted into each other, and the number has increased several times.

Song Yifei slowly closed his eyes, sensing a steady stream of heaven and earth vitality, separating from all things, entering the body through the acupoints around his body, and integrating into his own true qi.

Since all the tricks were broken, the vitality of the radius of a hundred zhang jumped, the air flow surged, all kinds of wind and grass, clues, all in his perception, the spirit and the true qi combined, turned into eyes, unobstructed.

In the stone room, Song Yifei, who opened his eyes, found that the air was no longer empty, but countless tiny particles of light.

Mysterious particles of light, flying and lingering, forming a various, irregular state.

These light particles, under the influence of the exercises, were attracted to the acupoints and projected into his body, turning into true qi.

The abrupt change made Song Yifei understand that the air was no longer air, but the endless Heaven and Earth Yuan Qi was formed.

"It's like the sunshine has life, and the original heaven and earth vitality is like this!"

The world has taken on a new look, and Song Yifei has stepped into a new world.

"How strong am I now?"
