In the cave, there was silence, and soft light continued to emanate from the light crystals embedded in the walls, illuminating the entire cave.

Guiguzi sat cross-legged on the side, his eyes slightly narrowed, and waited quietly.

At a certain moment, Guiguzi's vague eyes suddenly opened, looked at Han Chen in the center of the cave, and said with a smile, "Ready?"

As Guiguzi's voice fell, after a while, Han Chen, who was sitting cross-legged, slowly opened his eyes and exhaled softly.

When the second step of blood melting was completed, Han Chen did not rush to continue with the next steps, but stopped and continued to refine the medicinal power and integrate it into the blood to replenish the severely depleted essence.

After all, the consumption of essence qi caused Han Chen's body to fall into extreme weakness, and his state declined significantly, which was extremely unfavorable for the continuation of refining in the future.

The Blood-Melting Yi Bone Pill deserved to be among the sixth-grade level elixirs, and under the continuous nourishment of the medicinal power, the essence in Han Chen's body recovered extremely quickly.

In just half an hour, the essence in the blood completely recovered, and not only that, but it was even stronger than before.

His eyes fell on Guiguzi, and Han Chen nodded in response, "Ready!"

Guiguzi nodded, then his face suddenly became serious, his eyes were solemn, and he said slowly: "The bone marrow is the most essential part of the human body, mainly hidden in the bones, and the bone and marrow are closely interdependent, regardless of each other. Therefore, the next bone boiling and marrow refining must be carried out together!"

After a pause, Guiguzi took a deep breath and said, "Three-step refining." You've come to the last step, and this step is the most important one. Whether you change your physique or not, it all depends on whether you can take this step!"

"Teacher, I understand!" Hearing Guiguzi's words, Han Chen's face also became solemn.

I thought that with the experience of the first two steps, this third step was hard work, even if it was extremely difficult and painful, Han Chen believed that he would be able to get through. But if the bone boiling and marrow refining were carried out together, Han Chen couldn't help but feel extremely heavy pressure.

But at this time, he has no way back, no matter how difficult and painful it is. You have to grit your teeth and bear it. Get through it.

Han Chen took a light breath, then his eyes lifted and his mind sank into his body, controlling the rapid operation of the Nine Styles of Naling. At the same time, under the traction of the mind. The medicinal power that is constantly refined. Through the flesh and blood, it poured towards the bones of the whole body.

The pure medicinal power quickly passes through the flesh and blood. Came to the bones in the depths.

"Let's start!" At this time, Guiguzi's old voice sounded softly in Han Chen's mind.

As if the horn of an attack had been sounded, the power that was quickly used rushed over like a crazy tsunami wave.

The cool and pure medicinal power quickly penetrates into the bones like being absorbed by a sponge.

"Hmph" In an instant, Han Chen's body suddenly trembled, and after half an hour of pranayama, his face, which had recovered his blood, was also pale in an instant. Although he had already felt this pain when he was forging his body, the sharp pain that emerged from his body at this time was not at all comparable to that when he was forging his body, Han Chen couldn't help but snort in pain.

Gritting his teeth and enduring the severe pain, with the experience of forging the body, Han Chen's mind was tight, while resisting the severe pain that was even stronger than when he forged the body, he also ran the exercises more quickly, and kept pouring the medicinal power from the refining into the bones.

After about a cup of tea, Han Chen suddenly felt that the sharp pain emerging from his body seemed to be gradually weakening, but in his soul perception, the refining in his bones did not stop, and continued unhurriedly.

Although I don't know what is going on with the Dao, this is a blessing for Han Chen, and he can't help but breathe a sigh of relief.

Han Chen didn't know what to do, this was because his will, after refining in the second step of melting blood, became more tenacious, so he was already able to form resistance to the severe pain in his body.

"Ahh

However, in the next moment, Han Chen's eyes suddenly exploded, and a roar full of poignancy suddenly roared out of Han Chen's throat.

Guiguzi's eyelids jumped, and his gaze quickly fell on Han Chen, only to see that at this time, the latter's pale face was hideous, and the roots of the green tendons burst out, like a small cyan snake, constantly beating. Beads of sweat the size of beans gushed out like springs, then rolled down and dripped on the ground.

"The medicinal power has been integrated into the bone marrow, and the bone boiling and marrow refining are going on together. Keep your mind and don't be distracted!" Guiguzi let out a deep sigh, and his voice was wrapped in soul power and directly transmitted into Han Chen's sea of knowledge.

Reminded by Guiguzi, Han Chen barely recovered from the severe pain, his teeth clenched, and he tried his best to calm himself down.

But boiling bones and refining the marrow together, how can the severe pain produced be so easy to resist.

It is like a sharp steel knife, scraping violently on one's own bones, and it is like a hot flame, burning and calcining in the bone marrow, which is the real pain that penetrates deep into the bone marrow. Compared with the pain of forging the body, it is several times stronger, and this pain can make people easily fall into collapse.

The sharp pain in the body that boiled the bones and marrow came like a tidal wave, wave after wave, and it kept bombarding Han Chen's nerves.

His eyes turned red and eventually turned red, his teeth clenched, and from time to time there was a 'gurgling' sound from being overwhelmed, and wisps of blood continued to burst out of his gums and from the corners of his mouth.

Fortunately, Han Chen's mind did not sink because of this, and he was still awake. Although because of the severe pain, I couldn't concentrate my mind and run the exercises. However, under the strong will, such as the second step of blood melting, the exercises had no effect at all, and they were running extremely wildly, refining the medicinal power and integrating it into the bones and bone marrow.

The refining process proceeded steadily and rapidly.

Seeing this scene, Guiguzi couldn't help but breathe a sigh of relief. But he still didn't dare to take his eyes off and stared at Han Chen in the slightest.

In the cave, calm was restored again.

Outside the cave, the waterfall roars and the shadows of the trees linger.

As the silver moon moved quietly in the sky, the night slowly passed.

Two hours later.

When dawn came, first a ray of light rose from the sky, and then a round of fiery red sun gradually climbed into the sky, and the blazing light illuminated the heavens and the earth.

Between the mountains and forests, a song of insects and birds sounded from time to time, which was extremely peaceful.

In a cave.

"Let's da, let's da" At this time, the pupils and whites of Han Chen's eyes were no longer visible, and only a red color remained. The teeth in his mouth had already been bitten apart, and blood kept pouring out of his gums, cutting through the corners of his mouth, and dripping down.

At this time, Han Chen had already entered a state of confusion because of the severe pain for a long time, although his mind was not blurred and unconscious, but it was not much different.

Except for the thought of 'sticking', everything else is forgotten. Under the shroud of will, the exercises in the body are still running rapidly, and the bone boiling and marrow refining continue steadily.

This state of affairs did not last long.

At a certain moment, Han Chen's body trembled slightly, and then a trace of fiery red color slowly appeared on his skin.

"It's really a little guy with amazing perseverance, and he really let him carry such pain and persist for two hours, such achievements, even if the old man has never seen a few in his life. Next to him, Guiguzi, who had been paying close attention to Han Chen, discovered this scene for the first time, and his face was immediately full of amazement.

Then he breathed a heavy sigh of relief, and continued with a relieved face: "Now the foundation of the fire spirit in the bones and bone marrow of this most dearly old bone has also been refined. This is the last step, boiling bones and refining the marrow, and it is finally going to be completed!"

After a while, Han Chen's skin had turned blood red, and just like the previous two times, fiery fire spirit qi quickly gushed out from Han Chen's skin.

If the foundation of the fire spirit in Han Chen's body is divided into ten.

Then the base of the fire spirit contained in the skin and flesh is one and a half, and the base of the fire spirit contained in the blood is two and a half. And the remaining sixty percent is completely taken up by this bone and bone marrow.

The huge fire spirit base in the bone and marrow was refined, turning into fire spirit qi gushing out continuously, and Guiguzi refined it with samadhi true fire seventeen times before finally stopping.

Refining the most trace of fire spirit qi in the air, Guiguzi exhaled lightly, and his eyes turned to Han Chen, who was sitting cross-legged at this time, and had not yet woken up, and there was a hint of expectation in his old eyes. (To be continued......)
