In the dim stone room, the mist steamed again.

A metal tripod replaces the previous water tank, the lid is closed, there is no flame under the tripod, but there is a steady stream of water vapor gushing out of the tripod.

This is Yu Lie sitting cross-legged in the bronze tripod, refining his own poisonous skills.

If someone is in the stone chamber, in addition to the sound of water vapor rushing out, they can also hear the sound of Kaka chewing and crushing.

Yu Lie was hidden in the bronze tripod, he sat cross-legged, his head bowed, a thick skeleton wrapped around him.

This skeleton is nothing else, it is the skeleton of the Black Snake Fish King.

After hunting the Black Snake Fish King, Yu Lie dissected the other party on the same day, took out fish gall bladder, fish roe and other organs one by one, and selected medicinal materials, mixed with them, cooked the fish king, and used it for his own cultivation and consumption.

Now it has been six or seven days since he hid in the copper tripod, and the entire black snake fish, except for the part that was specially retained, the fish meat organs, fish blood and fish poison have all been devoured by Yu Lie, turned into his own qi and blood, and refined his poisonous skills!

Even the bones on the fish king's body that were as hard as copper and iron had been eaten by Yu Lie and there was only one vertebra left.

Bang dang!

There was a strange sound in the copper ding, and Kaka's voice became louder, and Yu Liepan sat in it, picked up the huge and hard crest vertebrae of the Black Snake Fish King, put it in his mouth, and gnawed it up.

The creaking sound kept ringing, as if gold and iron were striking.

The spine bone of the king of fish is the hardest place on the body of the king of the black snake and fish.

Thanks to Yu Lie, he not only repaired the copper tendons and iron bones, but also soaked the vertebrae of the king of fish crests in advance, otherwise, he really couldn't bite this bone.

It took about three or four hours, and Yu Lie swallowed all the fish king spine bones, and he suddenly felt a fierce feeling of heat rise in his abdomen!

The spine bone of the king of fish, also known as the "poisonous dragon bone" in Blackwater Town, has precipitated all the toxins accumulated by the black snake king for nearly a hundred years, devouring creatures of all sizes, and fish gallbladder, or even more powerful and stamina.

Use it to make soup, ordinary people smell it, and they may be poisoned and die violently, let alone eat it dry.

But in the same way, if this "poisonous dragon bone" is refined into an elixir through a good prescription, it can also be greatly replenished, beneficial to cultivation, and can even assist the left Taoist to break through to a high-level Taoist child.

Yu Lie didn't have such a recipe in his hand, and it was not convenient for him to find someone to refine it into an elixir, but he practiced poison skills, and after concocting it slightly, he digested it in his stomach, and what he obtained was also not to be underestimated.

Throat!

A metal thumping sound suddenly sounded, and Yu Lie was in the bronze tripod, and opened his eyes reluctantly, his eyes glowing green, like wolves and jackals, fierce and indifferent.

Sonorous!

The metal shook again, and a fist mark appeared on the surface of the copper tripod.

Immediately afterwards, the palm imprint was shot, which was played from the inside of the copper tripod, which was clearly and deeply highlighted!

Boom! The copper tripod seems to be filled with gunpowder, and the whole tripod vibrates violently, and the fists, palms, and fingers are like torrential rains, continuously hitting the copper tripod.

The huge and complete copper tripod, after only a dozen breaths, made an overwhelmed sound, and the top lid could not be closed, leaking out a huge opening.

The pungent and corrosive mist pounced out of the copper tripod, causing even more damage to the already mottled roof of the stone chamber.

It's been a few dozen breaths in the past again, boom!

The copper tripod exploded, splitting apart, and pieces of fragments rolled down the scene.

In the vigorous mist, a strong and powerful body appeared where the copper tripod was, looming, like a giant beast that had broken free from its cage.

Yu Lie was bowing slightly, pinching his hands and sitting quietly in the fire pit. His face was calm, as if the violent knock in the copper tripod had just been made, not by him.

Thick mist of water was rising from Yu Lie's flesh.

It turns out that the reason why there is no flame spontaneous combustion in the copper tripod just now is because Yu Lie's own blood is vigorous, boiling to the extreme, and the blood is like a furnace, and the medicine in the tripod is evaporated!

At this time, the qi and blood on Yu Lie's body were still surging violently, and his body was very hot!

The remaining medicinal liquid poured into the fire pit was continuously evaporated by his body, causing his body to continue to be filled with smoke, and he gradually appeared to have a few traces of Dao Qi, and there was a feeling of immortal wind Dao bones.

In addition, the muscles and muscles in Yu Lie's abdomen were also constantly trembling, driving the muscles and bones all over his body to shake in unison.

Yu Lie could feel that the skeletal membranes all over his body were transforming at an unimaginable speed, and in addition to his own qi and blood, there was actually a cold and arrogant strange force, which was released from the spine bone of the Fish King in his abdomen and absorbed by his physical body.

Half a day passed, and Yu Lie was firmly entrenched in the stone room, refining his muscles and bones.

Until dawn the next day.

Yu Liecai slowly opened his eyes, and his eyes showed joy.

He jumped up from the ground and tapped his fingers on his body, and immediately heard the metallic sound of the pit.

Yu Lie hooked his foot again, picked up a broken piece of copper tripod fragments, and with his fingers, he directly pinched the copper tripod into slag.

At this time, his body bones really became cast in copper and iron, or to be precise, ordinary copper and iron metals were not as strong and hard as Yu Lie's current body bones!

Yu Lie Haosheng checked it, and in addition to joy, his eyes also showed a trance.

At this time, this situation, it seems that he has not only cultivated the second layer of poison skills, bone poison, but also completely digested the copper tendons and iron bones!

What a bonus!

After Yu Lie hunted the Black Snake Fish King, what he originally planned was to cultivate the poisonous bone first, and then use the poisonous skill of the Zhongcheng realm to increase the digestion speed of the copper tendon and iron bone, and then work harder to completely digest the change of the copper tendon and iron bone.

As a result, he didn't expect that while cultivating the bone poison, he would complete the digestion of the copper tendons and iron bones at the same time.

Yu Lie came back to his senses from a trance, and he looked at the stone house full of copper slag, and his eyes were overjoyed:

"The digestion of the copper tendons and iron bones means that I can start to prepare, and even immediately proceed to the next transformation. That's at least a month ahead of schedule! ”

The extra month not only made it easier for Yu Zuo to make better preparations for the next fight out of the town, but also allowed him to take the opportunity to take advantage of the fact that he was still in the town to make better preparations for the change of "cutting hair and washing the marrow".

Even if he can't complete the hair cutting and marrow washing in the next month, he will break through to the level of the upper Dao Tong. But with sufficient preparation, Yu Lie is also sure that when he is outside the town, he will successfully break through!

At that time, the matter of "big soldiers" will no longer be a danger for him, but a great opportunity to take the opportunity to improve his fighting experience and collect money!

Yu Lie stood in the stone hut and began to think about the general changes.

The fourth and last change in the realm of Daotong is called "Cutting Hair and Washing the Marrow".

After the completion of the process, the Taoist will be able to shrink the pores and essence of the body, control the blood and qi by himself, and can hold his breath, so that others can not see his shape, and the wolf dog cannot find his trace!

At this time, the Taoist was unblemished, and there would be no peculiar smell if he didn't wash it for seven days, and his ability to control the body was becoming more and more at the limit.

Once it reaches the point where "one feather can't be added, and flies and insects can't fall", it means that the hair is cut and the marrow is completed, and you can consider breaking through to the realm of eight-grade Taoist disciples.

Yu Lie thought about it, couldn't help touching the hair that had just grown back on his head, and sighed lightly:

"Aren't you going to be bald again?"

But the next moment, he suddenly thought of the book "Eighteen Years of Experiences in Blackwater Town" that he had read a few days ago, and it seemed to be mentioned in that book.

That is the key to cutting hair and washing the marrow, which lies in the latter, refining the bone marrow and giving birth to strong blood to nourish the whole body!

In fact, it has no effect on whether to shave or not, what it really means is that in the process of completing the hair removal and marrow washing, the ability to control the pores is gradually enhanced, and in the end, all the pores will be able to close by themselves, so that all the hair on the body will fall out, almost hairless. This process is the real meaning of "hair cutting".

Its representative is the process of change of the Taoist, just like "a feather can not be added, flies and insects cannot fall", which is convenient for the Taoist to test their own progress.

Therefore, the real essence of the transformation of "hair washing and marrow washing" lies only in the marrow washing and the blood that can be born after washing the marrow.

And according to the nature of the blood after Dacheng, there are several divisions, such as lead blood, mercury blood, gold blood, jade blood, and so on......

At this time, the strength of the blood is related to the strength of the true qi condensed by the Dao Tong after he was promoted to a Dao disciple! Because true qi is a thing that is originally refined from the qi and blood of Taoists, there is a saying of "refining and refining qi".

The drugs that complete the transformation of hair washing and marrow washing are only related to marrow washing and hematopoiesis.

Thinking about this, Yu Lie suddenly had a strange look in his eyes.

He lowered his head and clenched his fingers, and suddenly there was a touch of black intent flowing on his palms and fingertips, which was extremely similar to the original Black Snake Fish King, which was quite strange.

Yu Lie lightly cut through his fingertips, and a drop of blood with black intent slowly seeped out, and then dripped onto a piece of copper tripod fragment.

This drop of blood, like lead and mercury, slid heavily, and after a few breaths, it slowly dispersed and corroded out of the pit......
