In the depths of the dark mine, a little dark red light shines through, which is bewitching and weird.

A man in black in a cloak stood in the middle of the mine, where a large hall had been dug out, where the miners usually rested, and the kettles, porcelain bowl fragments and other things were piled aside.

A circular red formation filled the entire hall, and it was found that it was a blood-red strange symbol, forming a large circle with a diameter of ten meters, and the symbols in the formation slowly swam, as if they had life.

The man in black stood in the center of the formation, and after swimming in a circle, the blood-colored symbols in the rune array gathered on the soles of the man's feet, and finally were all absorbed by the red lamp in the man's hand.

"It's coming, it's coming, the soul lamp is almost finished, Qingniang, we're almost successful......"

The man's tone was frenzied, and the blood-colored flames in the lamp continued to jump with the man's words, shining brightly in the darkness.

At this time, the situation in the hall was revealed, around the red formation, countless corpses were piled up on top of each other, these people were wearing some coarse linen clothes, and many patches could be seen on them, obviously the civilians in this vicinity were absent from work.

The blood on their bodies continued to flow out, as if there was some traction, and dozens of blood-colored streams slowly flowed towards the circular formation in the center, like blood vessels.

"Hmm, the white ghost is dead, could it be that the Xuanlingmen gang have already found here?"

The man in black suddenly paused and muttered to himself

"But it's okay, I'm done here, haha, no one can stop us anymore......"

"But the black abyss side also has to deal with it, you can't leave your tongue behind, it's just right, the Xuanlingmen raid, the blood sacrifice failed, I died on the spot, what a perfect excuse"

The man in black laughed like a night owl, and saw the red lamp in his hand swaying, and a small red light suddenly split out, and swooped into a corpse on the ground.

Click

A thin layer of red flames erupted from the man's body, and a wrinkled palm crept out.

The breeze turned, and there was no sound in the cave, only a black-robed figure sitting in the center of the red formation, his eyes glowing red in the darkness.

............

Mining village, in the wing.

Ye Cheng sat cross-legged, the faint moonlight projected into the room, and Ye Cheng's whole robe swayed silently.

A layer of faint silver-gray covered the upper body of Ye Cheng, and a cold and powerful aura came from the surface

"The iron tire is divided into six layers and three realms, the first realm is the black iron body, after training, the body is as strong as fine iron, invulnerable, the second realm is a red bronze body, and the muscles and flesh are like red copper, at this time, even the condensation realm monks can also fight, and even because of the refining body, the physical strength is long, and it can overwhelm the condensation master."

The refining body has reached the realm of red copper, and the skin and flesh all over the body have reached the limit of the mundane, and the gestures are all extremely powerful, and the combat power is extremely long.

Unlike the masters of the inner family who count their internal qi to fight, body refining martial artists don't have to worry about these at all, their bodies are the strongest weapons, their physical strength is unfailing, and their combat power is endless, which is the most terrifying thing about body refining martial artists.

"But the peak period of a body refining martial artist is twenty years, and when the body function declines after the age of forty, and the essence and blood in the body are exhausted, even the body refining cultivation that has reached the condensation realm will also regress, if you don't pay attention to the warmth before, it will even directly be an outbreak of old injuries and paralyzed for life."

"And the third realm of iron fetal skill is the realm of warmth, a horizontal practice of external skills, and the final realm is actually the realm of warmth itself, should it be said sad or pitiful"

Ye Cheng sighed lightly, the iron tire skill was already close to the internal strength when it reached the third layer, and he used the terrifying physique qi and blood he had exercised to reverse the internal strength, and use the power of qi and blood in his body to nourish himself and keep his state at its peak.

After reaching this level, the qi and blood of the whole body can be controlled freely, and the power that bursts out can be compared to the master of the transformation realm, but the founder used this terrifying power to warm himself and gave up the transcendent power, which is what kind of blow to a martial artist who is arrogant and always chasing the peak.

Closing the booklet, Ye Cheng couldn't help but sigh lightly

"The predecessors who created the iron tire work, I didn't know what the mood was at that time"

The martial arts of the world, whether it is an inner family or an outer family that walks horizontally, is extremely difficult, there are too many masters in the inner family to the point that they still can't see the internal qi door, and the pain experienced by the foreign masters in the process of cultivation is even more inhuman-level, fire and water refining, poisonous insect bites, which is something that ordinary people can bear.

Thinking of this, Ye Cheng was suddenly extremely glad that he had a small frame of the Northern Spirit, and as long as the source point was enough, he could be promoted to the martial arts, otherwise he might be spinning outside the gate of the martial arts for the rest of his life.

He knows his own situation, the meridians and internal qi induction can only be said to be ordinary, with his qualifications, even if he has the resources of the Ye Mansion, he can give birth to internal qi by the age of thirty or forty, which is already thankful.

"Since I have the Northern Spirit, then I must go to the pinnacle of this world to see what level human beings can reach."

Seeing Zhao Yingchen's appearance when he broke through tonight touched him too much, and when he learned that he had broken through to the realm of internal qi, the surprise, excitement, disbelief, doubt, and all kinds of complex emotions on his face were mixed on his face, and it was only at this time that Ye Cheng really realized that internal qi was such a rare thing, which was the admiration and pursuit of ordinary martial artists all their lives.

And with the small frame of the Northern Spirit, he rushed through the internal qi realm, and reaching the inner qi realm did not give him too many surprises at all, and even felt that everything was taken for granted.

Gathering his chaotic thoughts, Ye Cheng once again cast his gaze on the small frame of Beiling under his eyes, which was quiet and suspended as usual, but he felt inexplicably at ease

"The first layer of the Iron Fetal Gong allowed my upper body to complete the black ironization, but even with the weakening of the Xuanyang Internal Qi Protective Body, it still didn't completely block the blow of that ghost."

Under the moonlight, the silver-gray light on the upper body of Ye Cheng's body shone, like a freshly forged fine iron, with a cold light.

He wiped his back, and a trace of bright red blood appeared, which was left behind by the ghost thing Bai Aya's blow, although the ghost thing's attack was weakened by Xuanyang's internal qi, but it still pierced the defense of the iron tire gong.

"Originally, I was going to go step by step, but it seems that I can't wait, the martial arts are refined, if you don't advance, you will retreat, I am still timid, it's ridiculous"

The source point was enough, Ye Cheng could have raised the iron tire skill to the level of the black iron body in one go, but the inhuman pain made him retreat a little, and considering the preciousness of the source point, it also made him unable to make up his mind.

But today's events made him completely let go of luck and cowering, ordinary martial artists fought to the death, just seeking a breakthrough, and he was afraid of this little pain and let himself stop, it was unforgivable

Ye Cheng's gaze turned to the small frame of Beiling without hesitation, and pointed at it

"Iron Tire Gong Second Layer (Black Iron Body)"

The airflow changed, and with the change of the handwriting on the small frame, a huge force suddenly surged out of Ye Cheng's body

"Ahh

Ye Cheng screamed miserably, trying his best to endure the pain in his body, and the power that suddenly surged out of his body was extremely violent, like a scorching knife, constantly flowing in his body.

boom

A cloud of blood mist erupted from Ye Cheng's shoulders, the bright red muscles were revealed, and they kept squirming, and Ye Cheng's body was like blowing up a balloon, constantly inflating, and in the blink of an eye, a giant man with a height of more than two meters appeared in the room.

The banging sound continued, and clouds of blood mist continued to explode from Ye Cheng's body, and he soon became a bloody man

"The old muscles and skin can't withstand my current strength, and the Iron Fetal Gong is reshaping the flesh and blood of this body"

Ye Cheng's eyes were wide open, and under the severe pain, there was a trace of blood on his eyelids, and the bright red muscles were like worms, slowly squirming, and a new layer of skin gradually covered them.

The skin muscles were generated in a short period of time, and the itchy feeling made him can't help but want to tear off the flesh and blood all over his body, but Ye Cheng was so stubborn that he couldn't help but punch the ground, and the hard stone slab was quickly filled with fist marks half a foot deep.

I don't know how long it took, the room finally regained calm, Ye Cheng was still sitting cross-legged, but his body had returned to its normal size, but the strange thing was that the skin on his body had now turned into a deep black, and the moonlight seemed to be absorbed on him.

"The black iron body is complete, the defense is twice as strong as before, plus the internal qi of Xuanyang, now even if you stand and let that white-clothed ghost thing fight, it won't hurt me at all."

Ye Cheng suddenly opened his eyes, and a silver lightning seemed to flash in the dark room.

"The physical control is a little uncoordinated, it should be the reason for the sudden improvement, and the iron tire skill can no longer be improved in a short time"

Ye Cheng felt the swelling sensation in his body and said softly.

Although the muscles that were torn and regrown were repaired by Iron Fetal Gong, this breakthrough was too explosive, and full recovery still needed recuperation.

Ye Cheng threw a punch casually, and his black arm suddenly slashed, leaving an afterimage in the room.

"The strength, speed, and explosiveness have all been increased by about double, and the power is not inferior to the master of the third layer of the inner family."

"And the most terrifying thing is defense"

Ye Cheng subconsciously urged the iron tire to work, and the black streamer covered his body, as if covered with a layer of black film.

Ye Cheng took out the close-fitting dagger and slashed it hard at his chest, the black streamer shone, the dagger actually slipped out of thin air, and the black light trembled slightly and regained its calm again.

"It's not in vain that I spent these 15 source points"

It takes 10 source points to improve the iron tire power of the first layer, and another 15 points to the second layer of black iron body Dacheng, Ye Cheng looked at the source points on the small frame of the North Spirit

Source Point: 45

"The remaining source points are no longer enough to raise the Xuanyang Gong to the sixth layer, but it is enough to improve the Iron Fetal Gong, but it's a pity that the body can't stand it."

Ye Cheng had been thinking about accumulating source points and improving Xuanyang Gong before, after all, only internal qi could cause effective damage to ghosts, which made him fall into a misunderstanding

"If my defense is improved to the point that even ghosts can't break through, then isn't it just that ghosts can kill as much as they want, and they don't have to pursue the improvement of the total amount of internal qi, and the improvement of comprehensive strength is the king."

Ye Cheng fought with ghosts, and every time he was in danger, in the final analysis, it was because of his own lack of defense, and every time he exchanged injuries for injuries, he was embarrassed.

Now that he has made up for the shortcomings of his defense, Ye Cheng's strength is no longer comparable, and there are no dead ends in his body.
