Without much effort, these two people practiced the martial arts that people in the martial arts dream of. But it was so difficult to get to Dugu Duan, and it took a lot of effort to finally devour the 'thousand-year-old ice silkworm', refining the cold poison, and the true qi of the Northern Darkness became extremely cold.

Dugu Duan's heart understood that whether it was You Tanzhi or Duan Yu, they had only refined one of the poisons, and in order to cultivate a body that was invulnerable to ten thousand poisons, and he didn't dare to guarantee that he would have the same good luck as a fool, he found the Blue Phoenix and found the secret method of the Five Poisons Sect, fighting poison with poison, and now he has devoured the 'Thousand Year Ice Silkworm', who expected that the Five Poisons Secret Method was useless at all, and finally refined the Ice Silkworm, thanks to the 'Northern Spiritual Skill'.

"It's not self-inflicted. ”

Dugu smiled bitterly, sighing in his heart, it seems that nothing is absolute, it is something that he thinks is foolproof, who would have thought that there is a great danger in it.

Just when Dugu was thinking wildly, the fire poison of 'Manggu Zhu Clam' had invaded the eight veins of Dugu Duan's strange meridians, and Dugu Duan was not worried, he had the experience of refining cold poison, so he began to run the true qi of the Northern Darkness in his body, and he felt that the internal force of the cold washed the meridians, and the heat of the whole body was immediately reduced, and the fire poison retreated all the way, but at this time, the meridians in Duguduan's body were not opened, and the rest had all been opened, and there was no barrier, and the meridians were full of the true qi of the Northern Darkness.

The speed of this fire poison is extremely fast, although Dugu Duan's internal force is huge, but he has not practiced the Northern Spiritual Skill, and his control is slightly insufficient. Gradually, the place where the fire poison could escape became smaller and smaller.

Dugu was preoccupied, and the fire poison was in front. But he couldn't catch up no matter what, and his heart was calm. The Northern Darkness True Qi in the body is like an ocean, flowing to every meridian, but there is still one place that cannot be reached.

Dugu Duan only felt a heat behind him, and snorted in pain, the most feared thing finally happened, and the irreversible fire poison finally invaded the Du Mai.

The person who supervises the pulse starts from the inner uterus of the lower abdomen and descends to the perineum. Backward to the Changqiang acupoint from the middle of the back to the caudal sacral region, ascending along the spine, passing through the back of the neck to the Fengfu acupoint, entering the brain, along the midline of the head, ascending to the top of the Baihui acupoint, passing through the forehead down the nasal column to the tip of the nose to the Sujiao acupoint, passing through the middle of the person, and the gingival intersection point in the middle of the upper teeth.

Dugu is hot and dry. I felt that my back seemed to be burned by a raging fire, and the pain was unbearable. At this moment, his whole body was drenched in sweat, as if he had been fished out of the water.

Dugu has been through a hundred battles, although he has also been injured, but he has never suffered so much. It was the cold poison just now that made his whole body stiff, unconscious, and not unbearable.

Dugu knew that he couldn't wait. The cold Northern Darkness True Qi turned into a cone again, starting from the Changqiang acupuncture point. Shock the Pulse of the Governor.

In his heart, he understood that although he had opened up Ren's vein. However, it is several times more difficult to supervise the pulse than the Ren pulse, and if you are not careful, the meridians will be broken, and the merit will be ruined.

He has already consumed a lot of physical strength. But if you don't open up the Du Pulse, the fire poison of the 'Manggu Zhu Clam' will not be able to devour it.

This fire poison is not an internal force, the true qi of the Northern Darkness cannot enter the Du vein, but the fire poison can, it can walk in any meridian without hindrance, only by completely opening up the meridians of the whole body, can it be devoured.

Just now, the cold poison speed of the ice silkworm was not as fast as the fire poison, and he was able to devour it when Ren was connected, but the speed of this fire poison was extremely fast, and he no longer hesitated at the moment, he was engrossed, and the Northern Darkness True Qi in his body turned into countless torrents, violently impacting the barrier of the 'Changqiang Acupoint', only to hear a 'click', and the river-like Northern Hell True Qi drove straight into the Changqiang Acupoint.

Dugu's broken eyebrows were twisted into a figure-eight shape, sweat was raining down on his forehead, and the clothes on his body were soaked by sweat, although he trembled in pain, he didn't stop, gritted his teeth, and continued to rush to the acupoint without hesitation. The Du Mai belongs to Yang, which is the overview of the Yang meridians, which can be described as the sea of Yang Meridians.

This Ren Du has two veins, one yin and one yang, which constitutes the balance of the human body, just as the 'Manggu Zhu Clam' and the 'Millennium Ice Silkworm' suppress each other, if one of them disappears, the other will be out of balance.

Dugu Duan devoured the Zhu Clam and the Ice Silkworm, although the cold poison had been devoured by his Northern Darkness True Qi and integrated into it, but the fire poison was still raging, if it was devouring the fire poison, Dugu Duan did not dare to guarantee what would happen.

In the past, he had thought that these two poisons, one yin and one yang, were both rigid and soft, and if they could be swallowed at the same time, in addition to cultivating a body that was invulnerable to ten thousand poisons, he could also greatly improve his skills, but now that he had swallowed the red clam and the ice silkworm, he found that things were far from being so simple.

Dugu Duan only felt that the true air of the North Ming flowed to the Du Mai, the fire poison frantically retreated, the heat of the back has been reduced a lot, he was happy in his heart, he didn't care about the pain, he continued to rush to the acupoint, and soon passed the life gate acupoint, this acupoint was extremely dangerous, Dugu Duan cautiously rushed over, breathed a sigh of relief, rushed all the way, and soon arrived at the Shendao acupoint, and encountered blockage, so the technique was repeated, the true qi of the North Ming turned into a stormy wave, regardless of it, crazy impact acupuncture points.

After the Shendao acupoint, there is no barrier, and the true qi of the Northern Darkness rushes into the Fengfu acupoint behind the head, and the power is slowed down.

Dugu Duan knew that it had finally reached the critical moment, and at that moment, the true qi of the Northern Darkness moved forward little by little, only to feel that his head was buzzing, and the headache was unbearable, but he didn't dare to stop at all, the fire poison was close at hand, as long as he passed this last difficulty, not only could he devour the fire poison, but also open up the Du Pulse.

Ren Du has two veins and one pass, which can prove that he is congenital, crisscrossing the world, and is supreme in the world.

At this time, the fire poison entered the brain, Xu was forced to be urgent, and he also knew that there was no way out, and began to exert his power.

Dugu only felt a 'boom' in his head, as if Sun Wukong had encountered a tight spell, although he had earth-shattering skills, he was surrounded by a small golden hoop, and he was helpless.

I saw that at this time, Dugu Duan's originally pale face suddenly turned red, like a boiled prawn, and the frost of his hair was all evaporated, and he suddenly opened his eyes, red light flashed, and his eyes were blood-red.

Linglong, who has been paying attention to Dugu Duan, originally saw that Dugu Duan had refined cold poison, and was not happy, but who expected that in a blink of an eye, Dugu Duan was a hundred times more dangerous than just now.

"Brother Break, stabilize your mind!" Linglong said anxiously.

I saw that the bead in Dugu's mind space emitted a dazzling light, illuminating the gray sky.

Dugu had a headache and was about to lose consciousness, when he suddenly heard a voice in his head, he felt a burst of coolness in his head, as if it was a long drought and a rainstorm, the Lingtai was clear, his spirit was uplifted, and he immediately regained his consciousness.
