A thin white line stretched from the top of Ling Pill's spherical body to between the two strands, and at this moment, Yun Xiao's other hand was also at the end of the thin white line, and the general pulse qi drill was about to enter, as if it was carrying out some unknown means.

Sou!

When the pulse of Yun Xiao's hand penetrated into the spirit pill's body and urged out in a mysterious way, the back of the spirit pill's body, which was as fat as a leather ball, started from between the two strands, and a thin black line spread upward, and finally reached the place where the palm of Yun Xiao's right hand touched.

The two thin lines, one black and one white, seem to split the body of the spirit pill that swells like a leather ball into two halves, but the black and white colors are distinct, and the well water does not interfere with the river water between them, and there is no connection at all.

If there were some vein refining masters who had reached the spirit level, such as the Great Elder and Second Elder of the Jade Pot Sect, seeing Yun Xiao's movements at this moment, I am afraid that they would be so shocked that they would even drop their eyeballs to the ground, right?

Because at this time, the two black and white threads in front and back of the spirit pill's body are the two most important meridians above the human body, commonly known as the two veins of Rendu.

Starting from the Baihui acupoint at the top of the brain, through the Yintang Qingming, then to the chest and abdomen, and then to the dantian qi sea, and to the perineum between the two strands, this is the so-called Ren meridian, which is a central main meridian on the front of the human body.

The so-called Du pulse starts from the perineum between the two strands, passes through the Yu Ming Gate, then to the large vertebral acupoint, and finally ends at the top of the brain, which is the most important main meridian on the back of the human body.

Pulse qi cultivation is the power cultivated in the meridians of the whole body, and the meridians of the human body are large and small, and the pulse qi that can be stored is also more or less.

Under normal circumstances, the meridians above the human body are all connected, and the pulses and qi between each other can also communicate with each other, so that the pulses can be continuously generated during the battle.

But there are two meridians that are an exception, that is, the second meridian of Rendu, the most critical and important main meridian above these two people, must reach the realm of the meridian before it is possible to open up, before that, there is no way at all, even if it is Yun Xiao himself, he can't go against the truth of this heaven and earth.

The three realms of the mortal level pulse qi, the chong pulse, and the gathering pulse, the spirit level three realms of the chong pulse, the combined pulse, and the spirit vein, the combined pulse realm is a special realm that is one order higher than the chong pulse realm.

Even in the entire Xuanyue Empire, there are not too many cultivators who have reached the Merge Pulse Realm, and most of them are the heads of some powerful families, or sect elders.

What's more, even if you reach the Merge Pulse Realm, you may not be able to get through the Rendu Second Pulse in the fastest time, or the reason why the Merge Pulse Realm level is called this name is a process of merging the two Rendu Pulses together.

Only by truly connecting the two veins of Ren Du can this have the qualifications to break through to the spiritual vein realm, otherwise he will never want to step into the spiritual vein realm for the rest of his life.

Therefore, as mentioned earlier, if some high-level cultivators or pulse refiners saw Yun Xiao's actions at this time, they would probably laugh off their big teeth, because Yun Xiao only had the cultivation at the peak of the pulse channeling realm, and the spirit pill was only in the middle of the pulse channeling realm, and such two teenagers would want to do such a thing against the sky, which was simply whimsical.

Is Yunxiao whimsical? Of course not!

The reason why he wanted to combine the two veins of the spirit pill at this time was not only because the spirit pill was facing a life-and-death situation, but also because the spirit pill had a mixed element and a gas physique, which was not one in 100 million.

This kind of special physique, which is rare even in the Ninefold Dragon Sky, of course, cannot be the same as ordinary cultivators, maybe they will be despised and insulted when they are just born or at a low level, but once they can control the use of this special energy, then their cultivation speed will definitely soar.

Different from ordinary cultivators, the cultivation of the Mixed Yuan One Gas cultivator is certainly also pulse qi, but it is not an ordinary pulse qi, in a sense, when they were just born, they can actually try to open up the second pulse of Ren Du, but in this Hidden Dragon Continent, no one will have such an awareness at all.

This is a deep-rooted concept, not to mention the cultivators of the Qianlong Continent, I am afraid that they don't know that this is a mixed element and one gas that is unique in a hundred million, like the temperament of the head of the Zhao family, let alone find any high-level vein refiners for this "freak".

Of course, even if a high-level vein refiner knew about this possibility, he didn't dare to try it easily, and this was also the reason why Yun Xiao knew a strong cultivator of mixed yuan and one gas in the Nine Folds Dragon Sky at the beginning, so he had a little understanding, and even more because he had a method that all the vein refiners in the Hidden Dragon Continent did not have.

This method is called the "Ren Du Pulse Array", this is a special formation, and it is a special means to open up the second pulse of Ren Du, and it is also a method that Yun Xiao researched in his previous life after knowing the Mixed Yuan One Gas powerhouse.

This Ren Du Pulse Array can not only open up the fusion Ren Du Second Pulse as soon as possible for a cultivator who has broken through to the Merge Pulse Realm, but also has an alternative effect on the special physique of the Mixed Yuan One Qi.

It was these two reasons that combined that Yun Xiao did not hesitate to use this method, as long as the Ren Du pulse array was formed, the spirit pill would have a chance to truly connect with the Ren Du second line.

Once the two veins of the spirit pill are successfully connected, he will be able to initially control his mixed element qi, and when the time comes, this will make him miserable from childhood to adulthood, and even suffer from a special body that the family does not want to see, not only will it no longer be a burden to him, but it will also make him a super genius with extreme talent.

Of course, all of this has to be built on the basis of the success of Yun Xiao's Ren Du Pulse Array, or in other words, Yun Xiao's Ren Du Pulse Array has been successfully built, and next, it depends on whether the spirit pill can withstand the ravages of this Ren Du Pulse Array and the chaos of one gas.

Yun Xiao's two palms, one pressed on the top of the spirit pill's head on the Baihui acupoint, and the other stroked on the perineal point between the two strands, if it was in a normal human form, it would inevitably be a little embarrassing, but at this time, the spirit pill was just a ball of meat, and he didn't have so many scruples.

In fact, Yun Xiao didn't expect in his heart that this Governor Formation could really succeed, after all, at this time, he only had the cultivation of the peak of the Pulse Channeling Realm, and this formation could at least reach the third realm of the spirit level, or the low-level spirit refiner could use it.

What made Deyun Xiao a little happy was that this time, it seemed that the Ancient Dragon Jue was helping, just now, the pulse qi that connected him to the acupuncture points on the back of the Spirit Pill was a little unsupportable, but the Ancient Dragon Jue was running on its own, so that he could connect the back force.

What Yun Xiao has to do now is to let his pulse qi pass through these acupuncture points he had previously pointed, and enter the second vein of the spirit pill, and see if he can really open up these two main meridians, which is also the only chance for the spirit pill.

The night passed quickly.

And all night, Yun Xiao's hands never left the spirit pill's Baihui and perineum**, at this time his face was extremely pale, which was a reflection of extreme weakness, because his pulse qi was left with little left.

Although it has the special effect of the Ancient Dragon Technique, but the manpower is sometimes poor, after all, Yun Xiao's pulse qi cultivation is too low, and the pulse qi that can be stored in the meridians is too small, and it is already an extremely remarkable achievement to be able to hold on to such a night.

Click......

Beads of sweat slid down Yun Xiao's forehead to his chin, and finally dripped to the ground, but he couldn't wipe it with his hands at all, because he knew that this Governor Pulse Array had come to an extremely critical moment, and success or failure was all about it.

Or maybe Yun Xiao himself came to a critical moment, because if his pulse qi was exhausted, he would no longer be able to support the operation of the Fu Du pulse array, and this night's hard work would inevitably be wasted.

Even the thin white lines on the front of Reimaru's body and the black veins on his back seemed to have become a little dimmed at this moment, and it was obvious that he and Yun Xiao were both about to be unable to hold on.

"It seems...... Still can't do it!"

Feeling that the pulse qi in his body was getting thinner and thinner, Yun Xiao couldn't help but show a wry smile on his face, and secretly wanted to use this Ren Du Pulse Array at the peak of the Pulse Channeling Realm, and successfully opened up the second pulse of Ren Du for others, but he really overestimated himself.

Yun Xiao knew in his heart that maybe his pulse qi would be exhausted in the next moment, and the two veins of the Spirit Pill Ren Du could not be united, and they would even be counterattacked by this Ren Du Pulse Array, which was really self-defeating at this time.

Rumble!

Who knew that at this last critical moment, Cong Yunxiao's right hand was pressed into the palm of the Baihui acupoint at the top of the spirit pill's brain, but it suddenly erupted a fiery breath.

Feeling the warmth from his right shoulder to his palm, Yun Xiao's heart moved, he naturally knew that this moment was opened by the power of the ancestral veins that belonged to him, and would this be a turning point in a moment of despair?

It turns out that Yun Xiao's luck is really good, or the luck of the spirit pill is good, when the power of this ancestral vein is poured into the Baihui acupoint at the top of the spirit pill's brain, the white line of the Ren vein, which had already become dim, suddenly burst into white light.

It was as if it was a small stream, and suddenly it was poured into the water of a large river, and in just a moment, from the top of the spirit pill's brain to the two perineums, the white light was extremely dazzling.

Burst!

When a slightly strange voice that didn't seem to exist came into Yun Xiao's ears, his pale cheeks were instantly ecstatic, because he knew that the connection between the two veins of the Spirit Pill Ren Du was already half successful.

And this big surprise did not end, the white light that broke through the perineum of the spirit pill instantly transformed into a pitch-black color, and then a black light from the bottom up, in just a moment, it had already rushed straight to the brain and reached the Baihui acupoint.

It's like a reincarnation, Yun Xiao's ancestral vein power walked around the Ren vein and the Du vein of the spirit pill, and finally returned to the Baihui acupoint, as long as it can really break through this Baihui acupoint and connect with the Ren vein, then this time it will be considered a real great achievement.
