Sweltering, humid.

The steaming heat filled the stone houses in the remaining rows, causing drops of water to fall on the roofs.

Smack!

Yu Lie was sweating profusely, his feet were wet, he was shirtless, carrying a hammer and tongs in his hands, like an ironworker, and was working hard in his stone house.

The red fire pond occupies nearly one-third of the stone house, and the charcoal fire in it is paved layer after layer, and it is also arranged in the shape of the nine palace gossip.

Yu Lie flicked the top coals with tongs, put down the hammer in his left hand, scooped up a scoop of turbid liquid from the water tank, and poured it into the fire.

Sting! A fishy mist immediately rose from the fire pit and turned into a gray-white mist, which burned brightly.

Yu Lie was washed away by the evaporated mist, and suddenly felt that his face was hot, and his nasal cavity was filled with a foul smell.

What he had just poured was not an ordinary liquid, but a mixture of horse urine mixed with donkey blood.

If you want to complete the transformation of copper and iron bones, you can use ordinary charcoal, which cannot meet the temperature requirements for melting gold and iron.

Fortunately, there is a burning consumable called beast charcoal in Blackwater Town.

Its blocks are carved in the shape of animal heads or skeletons, a kind of stone charcoal, the temperature is just enough to meet the needs of metamorphosis, and it is also the main fuel for iron forging in the town's courtyard.

It's just that in the process of animal charcoal burning, it needs to be repeatedly poured with special water to fully burn, and it will not produce poisonous gas to kill.

However, after the horse urine mixed with the blood of the donkey, the smell produced is really unpleasant and irritating to the eyes. Many Taoist children in the town who burn fires and make irons suffer from harmful eye diseases, and their eyes are squinted all day long.

Whew!

Yu Lie stared at the red naked eye, and he recognized the color of the flames in the firepit, and found that it was already changing from red to blue-purple.

After waiting for a moment, he was sure in his heart: "The potion is ready, the fire is burning, it's time to start!" ”

Yu Lie gritted his teeth, he took off the clothes of his lower body, stood naked by the fire, took a clay pot, grabbed a handful of pale golden ointment from it, and applied it to his body.

He applied it very carefully, whether it was the eyelids, pinna, genula, the top of the head, the soles of the feet, etc., but all the exposed skin was wiped by him.

When it was all smeared, Yu Lie was covered in gold, and he stood on the edge of the fire like a bronze statue, with dark gold flashing.

This kind of ointment is the transformation ointment that Yu Lie spent a lot of money to buy medicine from the Danfang, mixed with half of the spirit stones, and carefully ground and configured.

The ointment has the effect of building muscles and invigorating blood, resisting fire and stopping heat, and only by applying it can Yu Lie step into the fire pit to transform, and even if he fails, he will not be in danger of his life.

The next moment, Yu Lie took a deep breath and slammed the clay pot into the fire.

Rumble!

A burst of blue-purple fire fought, the clay pot shattered, the beast charcoal tumbled, and the spirit stone powder remaining in the jar made the temperature of the entire fire pond suddenly fluctuate.

There are also flames tumbling in the remnants:

"Whether it's success or failure, it's up to us next!"

He held his breath, immediately stretched out his feet and stepped into the fire, and walked towards the center of the fire pond step by step.

A scorching, hot sensation appeared on Yu Lie's body, and he felt as if someone was picking at his skin, and there was no place on his body that did not hurt.

And this is still his own strong physique, and there is ointment to protect the body.

If it was an ordinary Taoist child, or there was no ointment, it would be an immediate scream of pain, unable to hold his breath, fearful, and the success rate of the transformation would be reduced by three points on the spot.

Enduring the pain, Yu Lie walked to the center of the fire pond step by step, and stood on a white iron lotus made of iron tapping.

The iron lotus burned red, and it can be said that it is the hottest place in the entire fire pond.

The soles of Yu Lie's feet fell, and even though he was supported by the ointment, he still heard the snorting and burning sound, as if he was roasting meat on an iron plate.

But even so, Yu Lie still didn't show the slightest sign of jumping away, he instead lowered his body and knelt down in the iron lotus, more exposed to the heat.

There is another noteworthy point to this step.

That is, the Taoist child must sit on his knees, not cross-legged, nor sitting, and his legs must be close together, and he must be tightly separated, so that the lower yin and the iron plate are completely separated!

Otherwise, if the lower yin is burned by the iron plate, it will be very easy to scorch the outer kidney of the Taoist child, which will make people regret it. Of course, Dao Tong who does not have an external kidney does not have to think about this, and he can choose his posture at will.

After Yu Lie sat down, his whole body was suddenly wrapped in blue and purple flames.

His eyes were in a trance, as if there were poisonous snakes licking his whole body, very vicious.

The pale golden ointment on his body was also burned and glowed, making him look like a hot iron nugget in a furnace.

Yu Lie could clearly feel that a trace of hot but pure aura was eroding his flesh.

Every skin on his body was constantly undergoing a process of destruction and repair, and his muscles were trembling.

But it was even more immense, and it also appeared all over Yu Lie's body.

At this time, Yu Lie finally couldn't bear it anymore, and let out a low roar in his throat:

"It hurts! Pain and pain......"

Compared with the severe pain at this time, the last time he experienced the sea of oil pot fire in the Dao Urn Courtyard, it was simply pediatric, and it was really just a test.

Yu Lie also suddenly noticed that the stone grinding oil pot and the four passes of the knife mountain and the sea of fire at that time may be related to the current transformation process, which can allow Dao Tong to experience the transformation process of "copper tendons and iron bones" in advance, and test the potential.

And Yu Lie was able to easily pass the four levels at the beginning, and his potential to complete the transformation now is naturally great.

Therefore, in the fire, Yu Lie only roared in his mouth, but his body did not shake at all, and he accepted the scorching of the fire pond solidly, without the slightest fear.

Charcoal burns, flames roll.

Half an hour passed, and Yu Lie was really like a bronze statue, kneeling among the iron lotus, motionless.

Because he had been kneeling for too long, the petals of the Iron Lotus had pierced into his legs, and his blood flowed out, which immediately became scorched black, making the Iron Lotus Flower mottled.

Another half an hour passed.

After enduring the scorching heat for a full moment, Yu Lie finally opened his eyes suddenly, and there was a hint of joy in his eyes.

In this hour, he was not only suffering from devastation and pain, but also absorbing the spiritual power and medicinal properties of the medicine.

At this time, Yu Lie could already feel that the skin membranes on his body had been polished, and it was no longer the same level of pain as before!

However, the transformation has not yet been completed, to be precise, the hour of roasting just now is just a warm-up or warm-up.

The change of copper tendons and iron bones does not only need to bake the skin film once, but also has to find ways to make the bones contact and quench!

The latter step is the key to determining the success of the transformation, and it is also the step that Dao Tong is most prone to death and serious injury!

Facing this step, even Yu Lie, who was sure, couldn't help but sink his face, and his hands trembled a little.

But he looked around at the fire, which had begun to darken, and knew that he had little time to hesitate.

The next moment, Yu Lie's face was pale, he closed his eyes again, and touched the top of his head with both hands.

A slippery sensation appeared on his fingers, and it felt excellent to the touch.

Before the transformation of copper tendons and iron bones, Daotong not only needed to burn incense and bathe, but also needed to clean his whole body, shave his hair and pluck his hair, and not a single hair could be left on his body.

Otherwise, the hair will obscure the ointment, hindering the application and affecting the absorption of the medicine.

And after stepping into the fire, Dao Tong has to endure a long period of scorching, and no matter how tough the hair on his body is, it will be burned to the core. It's better to dispose of it sooner rather than keep it.

Therefore, Yu Lie is now hairless, and his brain is still like a shelled egg, smooth and slippery, and even the stubble is not obvious.

He rubbed against the top of his head, claws suddenly growing on his hands.

There was a snort, and a stream of blood immediately flowed down from the top of his head, and was evaporated by the high temperature, setting off a fishy gas.

Yu Lie's face was distorted, his hands were raised above his head, and his muscles were bursting up.

On the top of his head, a large gash appeared, and the skull was revealed.

Yu Lie was alive and peeled off his scalp.

Roar!

Such a sharp pain made Yu Lie roar again, and his facial features were hideous, like a madman.

But after breaking his scalp, his body still didn't shake at all, his back was straighter, and he also stretched out his hand and steadily pulled down a mechanism next to him.

I saw that just above the heads of the remaining columns, there was a jar of boiling hot oil in it, and there was a gurgling sound coming out of it.

The mechanism pulled down, and the fire oil mixed with the other half of the spirit stone in the jar immediately fell, and fell on top of the rest of the column's head.

Sting!

The sound of frying and splashing sounded, and there was a smell of burning, and no matter how firm Yu Lie's mind was, his body was also trembling violently and shaking at this time.

An even louder howl rang out in the stone house.

Roast the body with the fire pit first, and then splash the skull with oil, these two steps are the standard transformation process of copper and iron bones!

The former was using the high temperature to forcibly force the medicinal power of the spirit stone into the skin and muscles of the Dao Tong, and polish the whole body.

The latter is to peel off the skin membrane, start from the skull, use the burning of the fire oil attached to the bones, and then force the remaining half of the spirit stone medicinal power into the bones of the Taoist.

And the latter is not a spill of the matter, because the skull is only the part of the human bone, and Yu Lie has to continue to cut his five fingers, elbow bones, sternum, knees, and even the spine...... So you can expose the bones, and then receive the oil shower.

Among them, the hand bones and spine, because they are related to the blood veins and meridians, will bleed or damage the meridians if you are not careful.

According to the records in the Taoist book, this step is also best done by a famous teacher, and you can also take things such as hemp boiling liquor to numb the mind of the Taoist child and reduce resistance.

Otherwise, once the Dao Tong's mind is not firm and his techniques are not in place, there is a great possibility of failure.

It's just that Yu Lie is in a place like Blackwater Town, so he doesn't have a master at all, and he doesn't dare to spend money to ask others for help, after all, as long as he dies on the stage, all his net worth will be someone else's.

This kind of thing is also common in Blackwater Town. This led to a large number of Taoist children, who were obviously qualified to carry out the change of copper muscles and iron bones, but they cowered and did not dare to carry it out.

Fortunately, Yu Lie was different, not only was he willing to be ruthless to himself, but he also exercised in the poisonous mouth of the Danfang for several months.

Now he can be described as ruthless and accurate, saying that peeling is peeling, saying that cutting meat is cutting meat, and he will never get touched by meat or broken bones.

Without using hemp boiling elixir, it can also facilitate Taoists to absorb the medicinal power in fire oil, which can strengthen the effect of transformation.

The sound of sneering and earnestness kept ringing in the fire.

Yu Lie tried not to regard his body as his own, but just peeled off the skin inch by inch and poured it under the hot oil.

Snap, stab!

The tin, the oil in the oil tank, also fell drop by drop, attached to him and burned.

As the fire oil accumulated more and more, Yu Lie was greasy and greasy, and his body was covered with a layer of flames, and the combination of heat caused the iron lotus flower he sat on to begin to melt.

When the charcoal in the fire pond was about to be burned out, the iron lotus flower in the center flickered again. A white light appeared, and the entire iron seat was ignited, and it slowly moved, closing little by little.

These lotus-shaped iron sheets are not ordinary iron sheets, but consumables and medicinal materials mixed with special metals such as lead and mercury, which can burn by themselves.

At this time, the temperature has reached, it has finally been ignited, and the transformation of copper and iron bones has come to the final moment.

The surging heat rippled like breath in the stone room, and the firelight on Yu Lie's body changed from blue purple to pure purple, and the air in the room was scorched and distorted.

In poisonous smoke, fire, and oil,

Yu Lie still just buried his head, continuing to take care of his skin and bones.

The closer he got to the end, the more he didn't want his transformation step to be a little mistaken, and he needed to continue to calm down.

If someone were in the stone house now, they would find that he was unhurried, as if he was just by the river, bowing his head and washing his clothes.

Yu Lie was already numb from pain.

Soon

The iron lotus flower was completely closed, and the rest of the column was wrapped in the flower bones, as if it was packed into a blast furnace.

As a result, the fire rose higher and higher, roaring to the top, causing the stone roof to crack and slag falling with a clatter.

And in the next, the petals of this iron lotus will be divided into three batches, and the first withering will be enough to warm up for three days and three nights, and all the medicinal power, not a drop of the remaining physical strength, will be blasted into the physical strength of the remaining columns.

The longer this process persists, the stronger the quenching effect will be, and the tougher the membrane muscles and bones will be.

Time passes.

One day passed, two days passed, three days passed.

For three days and three nights, the Iron Lotus completely fell, shattered into pieces, and finally revealed the remaining columns inside.

I saw that in the fire, Yu Lie still sat on his knees with his head bowed, like a prator.

Open eyes!

In the dim stone room, Yu Lie suddenly opened his eyes, his eyes unrestrained.

He whispered:

"Burn the tail of the body and pour oil on it, so that you can plant the golden lotus in the fire. Pick the scalp and scrape the white bones to get the copper tendons and iron skin! ”

I saw that his muscles and flesh were distinct, copper was cast in iron, and all the flames around him had been extinguished, and it was pitch black and white ash all around.

But around Yu Lie's body, the temperature was still scorching, as if there was still a fire burning.

This is the qi and blood of Yu Lie is like a furnace fire, which has not been extinguished for a long time, boiling and surging!

At this time, Yu Lie has completed the transformation of copper tendons and iron bones, his blood is like a furnace, and his skin is also hard, and he will no longer be afraid of swords, guns and arrows, as if wearing a heavy armor.

He only needs to shout loudly, and he can disperse some ordinary little ghost spirits, crush evil spirits, and show the power of Taoists.

If he dies, bury his body in the ground, it will not rot for thirty years, and it is a good material for blindly refining zombies.
