After Lin Feng carefully explored the situation in the little boy's body in the big urn, he had thoroughly understood the true principle of this so-called Human Yuan Spirit Pill.

The medicine tripod in the boy's body is still very different from the pill tripod of the Danding realm monk in the late stage of foundation building, and it can only be said to be a "virtual tripod".

And the medicine pill condensed in this void tripod is naturally not a serious eight hundred golden pill, but a void pill.

But this person's Yuan Ling Pill can indeed help the monks of the foundation building period to improve the success rate of the Dan, and even help the monks of the Jindan period to improve the quality of the Jindan.

The principle is actually similar to the method of the little brother who plotted to seize the small supreme spiritual platform.

The little boy in front of him, after the Void Ding and Void Pill in his body have matured, he will be provided to the monks in need, and then the Void Ding and Void Pill will be stripped from the little boy's body by a secret method.

For example, the other party is a monk in the Lingtai realm in the middle stage of foundation building, and he has been unable to condense Danding to be promoted to the late stage of foundation building.

After obtaining the Void Ding in the little boy's body, he can borrow the Void Ding as a framework, infuse his own mana, and finally condense a genuine Danding.

Then, with the help of the Void Pill that still exists in the Danding, in the same way, the Jindan will be knotted until the Jindan stage is successfully promoted.

In this Void Pill, because of the special medicinal composition, it faintly contains the two artistic conceptions of life and extinction, which not only provides spiritual energy and medicinal power, but also helps monks overcome the difficulties of life and death, which is the most important thing.

Some monks who have been unable to form a pill in the late stage of foundation building have the same method, except that they don't need a void pill, as long as the void pill is enough.

And the Jindan period monk, after introducing the Void Pill and the Void Ding into his body. With the Void Ding as the foundation, the powerful medicinal power and aura in the Void Pill as nourishment. You can get a chance to re-refine the golden pill in disguise.

It's like rebuilding in the furnace, if the refining is successful. The quality of Jindan may be upgraded to a higher level.

However, Lin Feng only explored a little and found the flaws.

This method is used to help Jindan monks improve the quality of Jindan, and it can only be applied to the fourth-class Huangdan, and the Huangdan is promoted to the third-class Bidan.

Bidan wants to improve to Lu, but the success rate is too low, almost zero, and Zhu Dan above Bidan is not even mentioned.

If this method is used to help the monks in the later stage of foundation building, it is because it is an opportunistic method with the help of the Void Dan, so even if the Dan is successful. can only get the lowest Huang Dan in the fourth class of Jindan.

Generally speaking, the better the pill, the stronger the human body's resistance, after using this person's Yuan Ling Pill once, the next time, it will have no effect.

Therefore, in a sense, acting on the monks in the middle stage of foundation building, the effect of the Human Yuan Spirit Pill is the most obvious, depending on the strength of the medicinal power of the Void Ding and the quality of the most refined Danding. It is even possible to derive the Danding of the upper three grades.

With the Danding of the upper three grades, even if there is no Void Dan, with his own strength, he is very sure of being promoted to the Jindan period.

In fact, the ancestor of Baicao was the first to create this secret method. It is to push backwards from the knot pill, from the golden pill to the danding, and then to the spiritual platform. Research out the method of forging and refining the upper three-grade spiritual platform, and even the supreme spiritual platform.

But after deducing to the Danding step. The Hundred Grass Ancestor had no way to continue, so he could only stay here.

After improvement. The human yuan elixir has become what it is now.

"Although there are flaws of one kind or another, they will still be very sought-after. Lin Feng sighed.

Jindan Avenue, the difficulty of life and death, this can be said to be the first major threshold faced by tens of millions of cultivators in the Tianyuan Great World Realm.

In the past, enjoy a thousand years of life, the road can be expected, even if it is only a yellow pill, can no longer progress, there is a thousand years of life, happy and happy.

If you can't break through, in less than two hundred years, you will lose your blood and blood, end up dying of old age, and die at the end of the day, turning into a cup of loess.

The difference is too great.

For the monks who have successfully advanced to the Jindan stage, the difference between Huang Dan and Bi Dan is also huge.

Not to mention whether or not you can advance to the middle stage of Jindan, just by fighting with people, the monk who formed the Bidan can beat the opponent who formed the Huangdan all over the ground looking for teeth.

For a sect, a few monks who formed a yellow pill raised the quality of Jindan to the level of Bidan, and the overall combat effectiveness suddenly went up a notch, if all of them could be promoted to the middle stage of Jindan in the future, it would be a completely different world, and the strength of the entire sect would have a small leap.

"It's just ......" Lin Feng's divine sense swept over all the fifty large urns, and was surprised to find that there were nearly thirty children in the large urns, and the Void Ding and Void Pill in their bodies had been shattered.

This kind of crushing should be natural crushing, in other words, it is the natural loss in the process of alchemy.

It may be because the child's body can't withstand the medicinal power, or because the Void Ding Void Pill itself is not stable enough, or even because the Baicao Ancestor, the alchemist, made a mistake in his own operation, and it is possible for any reason.

But Lin Feng looked at this scene, and his eyes became more and more cold.

The medicinal juice in the urn will be boiled dry, and every time the ancestor of Baicao comes to change the medicine, he will definitely eliminate the children who have failed.

In other words, the thirty children who have failed here at the moment are all shattered after the last time the Hundred Grass Ancestor changed the medicine.

Lin Feng observed it and found that the consumption rate of the medicinal juice was actually very fast.

In a short period of time, three-fifths of children have been eliminated.

Every time the dressing is changed, a group of children will be eliminated, such a high elimination rate, for the sake of these twenty children who are about to succeed, how many people have failed, and how many have been eliminated?

What happened to the children who were eliminated?

Lin Feng took a deep breath to calm himself down.

He felt it for a while, and he could be sure that these big urns must be closely connected with the mind of the Baicao Ancestor, and whether he was saving people or taking reinterest soil, he would inevitably alarm the Baicao Ancestor.

The mana prohibition here is not the same as the ice city outside, this so-called human yuan spirit pill is still in the process of refining, as the refiner, the Baicao Ancestor is more closely connected with their minds, Lin Feng does not dare to risk it with the Heavenly Realm Barrier easily.

"Huh?" Lin Feng's heart suddenly moved, hiding his figure.

The stone house was silent, only the medicinal juice in the large urn was bubbling, and then exploding.

Lin Feng hid to the side, but his eyes did not stare in the direction of the door, but looked at the corner of the room, staring at the wall there.

After a few moments, a small bulge suddenly grew on the blue-gray stone wall.

It was a small bump the size of a grain of sand, and ordinary people might not be able to notice anything unusual even if they looked closely.

But Lin Feng's gaze was staring at the small particles that suddenly appeared on the stone wall.

Gradually, something squeezed out of the stone wall, pale gold, particularly conspicuous on the gray stone wall.

It was a sand sand sand s

The sand sand emitted a faint golden glow, and the light became stronger and stronger, and the entire stone house was reflected in a golden patch at the end.

In the golden light, the volume of the sand sand gradually increased, and finally it became larger to a square circumference, and at the same time, the sand sand became transparent, revealing the two figures inside.

The golden light dissipated, the huge sand sand wheel disappeared, and the two people fell to the ground, both looking at the big urn in front of them with serious expressions.

One of them, a red-clothed girl with red hair and red eyes, and eyebrows like thin swords, was the monk of the Gale Society that he had seen in the Ancient Domain Daze that day, Yue Hongyan.

At this moment, the girl in red has a gloomy expression, and her whole person is surrounded by a suppressed and resentful aura, like a volcano that will erupt at any time.

And beside her, there was a young man in white, with a thin figure and handsome facial features, it was Kang Nanhua.

At this moment, Kang Nanhua, with a ruddy complexion and a peaceful breath, has completely recovered his health, and is no longer the sick appearance of Dazeli in the Ancient Domain.

It's just that Kang Nanhua at this moment, there is also a touch of darkness between his eyebrows, which makes Lin Feng secretly surprised.

In Lin Feng's impression, even if his face was pale and cold sweat broke out at the beginning, and he couldn't even straighten his waist, Kang Nanhua's mood was still calm and indifferent.

Now Kang Nanhua, the mana aura above and below Zhou's body is completely leaky, and it is a higher level than in the ancient domain Daze that day.

But his person is far less energetic than the original ancient domain Dazeli, and Kang Nanhua at this moment is like an old man who is about to die and has nothing to love.

It would have been a happy thing to meet old acquaintances in a foreign country, but Lin Feng did not show up to meet them.

Looking at these two people, Lin Feng's brows furrowed slightly: "One is okay, both of them have such expressions, is there something wrong with the Gale Society?"

And then ...... Why are they here?"

Yue Hongyan walked to the rows of large urns in the stone house, lifted the lid, and after seeing the scene inside, he trembled with anger: "This group of dog thieves from the Hundred Herb Sect actually did such a thing!"

Kang Nanhua's gaze swept in the stone house: "The previous time, we were blocked by the ice wall outside, and we didn't dare to enter, this time again, a big hole appeared in the ice wall, obviously artificial, the ancestor of Baicao had no reaction to this, and the means of the person who broke the ice wall were very clever." ”

"There's a good chance he's still here. ”

Yue Hongyan lifted the lids of one large urn after another, and let out a cheer after a while: "Xiao Huanzi is fine! Mr. Kang, Xiao Huanzi is fine!"

The sorrow between Kang Nanhua's eyebrows lightened slightly.

In order to find the missing Xiao Huanzi, they found Changchun Peak all the way and captured a monk of the Jindan period of Changchun Peak for information.

As a result, the Jindan stage monk who was held by Kang Nanhua happened to be the beneficiary of the first batch of human Yuan Spirit Pills refined by the Baicao Ancestor, and one of the few people in the know on Changchun Peak.

Under Kang Nanhua's interrogation, this person revealed the information of the secret Dan room of the Hundred Grass Ancestor, and Kang Nanhua and the two came to the cave in the belly of the mountain with the help of a strange treasure that could move space.

The other vigilances were all resolved by Kang Nanhua, but Bingcheng, if it was forcibly destroyed, it would inevitably alarm the Hundred Grass Ancestors, and the two could only return again and again in vain.

Today they came to investigate again, and suddenly found a hole in the ice wall, so they hurried in.

Compared with Yue Hongyan's joy, Kang Nanhua was obviously much calmer: "It's good if there is nothing to do, but I'm afraid that it will still be difficult for us to save him from the clouds, these big urns must be closely connected with the heart of the Baicao Ancestor, and if there is a slight change, the Baicao Ancestor will immediately feel it." ”

Yue Hongyan pursed his lips tightly, and his fingers clutched the mouth of the urn. (To be continued......)
