In front of Gu Dan, there is a "potted plant".

It was a large pot about half a zhang thick, filled with spiritual soil, and in the center, it was the three-leaf spiritual vein flower.

This elixir, three days ago, was still a second leaf.

After coming to the Buzhou Mountain Range for more than nine years, this is the first time Gu Dan has come into contact with a genuine elixir, and it is a realm-breaking elixir, and it is also one of the main medicines of Zhuji Dan!

Its value is quite high for monks in the late stage of Qi cultivation.

If it weren't for that, Lingzhentang wouldn't have taken him out as a publicity gimmick.

The elixir is cherished, and it is extremely difficult for ordinary people to even see the previous one, and having this thing is equivalent to having more hope for promotion and building a foundation.

Of course, for Gu Dan, this is not worth the effort he expended.

"Three-leaf spirit vein flower, it's not enough."

Gu Dan completely activated the Dongfu formation and opened the retreat mode, unless someone forcibly attacked the Dongfu, he would isolate all disturbances from the outside world.

Even if the monk who left him with the spirit talisman of transmission, he could only wait for his passive response at this time.

"I've proven the effectiveness of Aoki liquid too many times."

Gu Dan laughed lightly, "This time, let me see your limit." ”

The voice fell, this time Gu Dan didn't do any more styling, he simply stretched out his fingers, and at the tips of his fingers, a drop of green wood liquid flowed down, right in the middle of the three-leaf spirit vein flower in the potted plant.

"Hiss~"

The Aoki liquid fell on the three-leaf spirit vein flower, and there was no sound.

But Gu Dan seemed to hear something, it was the sound of rhizomes growing rapidly, breaking through the ground!

I saw that the three-leaf spirit vein flower, which was originally no more than the size of a person's palm, was slowly getting bigger and taller after absorbing that drop of green wood liquid.

After there was no movement at all, the palm-sized three-leaf spirit vein flower had nearly doubled in size, and the originally delicate leaves also stood upright, verdant and shining.

If the previous three-leaf spirit vein flower was still immature, then at this time, it was already a real maturity period.

"It's not enough."

Gu Dan did not stop, and when he waved his hand, he was naturally extremely arrogant, and the three drops of Aoki liquid immediately fell on the three-leaf spirit vein flower again.

"Hum~"

As three drops of Aoki liquid fell on the three leaves, some special aura fluctuated.

The aura of Gu Dan Cave Mansion suddenly began to converge rapidly towards the three-leaf spirit vein flower.

At the same time, the half-zhang thick pot was suddenly covered with cracks, and the fine and tough rhizome crossed the boundary, and the black spiritual soil glowing with spiritual light in it suddenly began to gradually lose its luster at this moment.

"Going to be promoted?"

Gu Dan was pleasantly surprised.

The effect of Aoki liquid on plants and trees seems to be stronger than that of people themselves!

At least the Aoki liquid is used on people's bodies, but there is no way to improve the strength of such a magnitude, and it is okay when it comes to martial arts, after turning to the immortal path, if it is not for the Aoki liquid itself is enough to compare with the Heavenly Spirit Root or even the Alien Spirit Root, there is really no sense of existence.

In Gu Dan's gaze, I saw that the three leaves of the three-leaf spirit vein flower were trembling together, and the fine lines on the leaves lit up one after another at this time, and the spirit patterns flashed, accumulated, and nurtured.

In a short moment, it seemed that decades had passed, and finally those spirit patterns converged with each other and condensed at the top of the three-leaf spirit vein flower.

As a result, a flower bone was slowly born at the intersection of the three leaves.

"Flowers?"

Gu Dan was stunned for a moment, and then reacted.

Three-leaf spirit vein flower, three-leaf spirit vein flower.

Before the three leaves, only the leaves were obtained, but the flowers were not seen.

Only when the real stamen blooms can it have the name of 'flower', and it can be called a spiritual object for building a foundation!

Although the effect of the spirit plant cannot be completely equated with the cultivation of a monk, it must wait until it completes its transformation before it can see its flower!

"However, there are a total of four drops of Aoki liquid, and they haven't bloomed yet?"

Gu Dan raised his eyebrows slightly, slightly surprised.

Aoki liquid, a total of seventy-two drops.

Counting the ones he left in the Xia Dynasty, now he only has fifty-six drops of Aoki Liquid on his body, so the Aoki Liquid can still exert the effect of the Heavenly Spirit Root level, which is why Gu Dan will feel that the Aoki Liquid is in a complete state, and it must be a strange spirit root.

And the Aoki liquid itself has the property of not increasing or decreasing, even if the Aoki liquid is left in the distance, as long as it is not consumed, he will not be able to recover here.

The gift left to the juniors, Gu Renran was not ready to take it away, so the Aoki liquid that he could use could only be fifty-six drops for the time being.

Of course, since the Aoki liquid is not in his body, it will gradually be consumed and returned if it is left outside, but quite slowly.

As for the recovery rate of Aoki liquid, it is about the extent that it recovers by one drop a month.

In other words, if all the seventy-two drops of Aoki liquid are consumed and wait for it to recover on its own, it will take six years.

"Show me your limits."

In the blink of an eye, two drops of green wood liquid spilled down in Gu Dan's hand.

The three-leaf spirit vein flower that was gifted was like a treasure, and the flower bones that were shy to be released finally slowly stretched out, and at the same time, a strange fragrance appeared in Gu Dan's cave, and the smell was refreshing, and even the speed of the aura was slightly accelerated.

A rather powerful aura fluctuated among the flowers, with a little fluorescent around the body of the three-leaf spirit vein flower, like a ribbon for it, which was condensed into a mist-like aura.

According to the division of the spirit plant by the Immortal Dao, there are three kinds of elixirs: ordinary elixir, realm-breaking elixir, and special elixir.

Ordinary elixir is an ordinary elixir, which is a standing elixir for refining various pills; As the name suggests, the realm-breaking elixir is something that can help monks break through the realm; As for special elixirs, their effectiveness is usually extreme, and they are difficult to find, and they are almost impossible to cultivate.

Between the three kinds of elixir, there are several grades: low-grade elixir, middle-grade elixir, high-grade elixir, and big medicine, which are divided into upper, middle, and lower three, respectively, corresponding to Qi training, foundation building, Jindan, and Yuanying.

As for the further up, most of them are called heavenly medicines, which already have extraordinary effects, and only exist in legends, and even monks may not be able to surrender.

Six drops of Aoki liquid, the three-leaf spirit vein flower has completely grown into a medium-grade elixir, and it is also a realm-breaking elixir, and its value has soared, which is of great use to the monks in the foundation building period!

And the limit of the spirit vein flower is the nine leaves, that is, the high-grade elixir that is very useful for the Jindan period.

"Show me your limits!"

Even though the three-leaf spirit vein flower has been promoted to a medium-grade elixir, Gu Dan is still not satisfied, and two drops of green wood liquid have fallen, and today he must see if this flower can be promoted to a top-grade elixir.

Two more drops of green wood liquid fell, and the spiritual mist that lingered on the three-leaf spiritual vein flower became a little more detailed in an instant, and on the three verdant leaves, the complex spiritual patterns flickered again, and the spiritual objects that were faintly intertwined with the flowers were resonating with each other, reflecting each other.

But at this moment, the spirit patterns of two of the blades suddenly began to flicker, and they could not maintain stability.

Even the spiritual things that were originally shining began to scatter and escape a little.

With such a change, Gu Dan, who was watching, frowned slightly.

The possession took a closer look and immediately discovered the reason.

The three-leaf is not right, it is the previous two-leaf spirit vein flower, and it is flawed!

Even if the third leaf is perfect with the help of Aoki liquid, it cannot make up for its innate shortcomings.

According to common sense, this three-leaf spirit vein flower that has been promoted to a medium-grade elixir, its limit is actually only two leaves, if it weren't for this, Lingzhen Hall would not be willing to let Gu Dan experiment with him.

After all, if it can become the main material of Tsukidan, the value will be completely different, and the strategic significance is extremely high.

It was because of the flaws that he could be allowed to pass.

But a flaw is a flaw, no matter how rich the nutrition of the crooked tree is, no matter how attractive the growth is, it can't straighten it.

"It's a pity."

Gu Dan sighed.

You won't be able to use it if you get a chance!

"Wait a minute. It is the imperfect cultivation of this spiritual vein flower in the process of growth, so it leads to flaws and cannot be perfected. Or is it that as early as when it was in the seed state, it was destined to have no chance of growing into a nine-leaf spirit vein flower? ”

Looking at this three-leaf spirit vein flower that had grown to the limit, Gu Dan suddenly thought of this question.

If it is the former, it is understandable.

After all, if Maxima doesn't give enough food, it won't be possible to travel thousands of miles a day.

But if it's the latter. It can't help but make people feel cold, and even make people feel that everything is already predestined.

At any time, fatalism itself is full of malice, and Gu Bao is especially disliked.

There is no answer to this question at this time.

You can only wait until the next day to get a bunch of elixir seeds, and try them one by one with Aoki liquid from the nascent state, so that you can achieve results.

But it's a pity that the three-leaf spirit vein flower in front of me has no seeds - this flower can only take root in a complete state, condense into a small spirit vein, and then differentiate into a new spirit vein flower, otherwise it is impossible for Lingzhen Hall to take it out if his brain is pumped.

This is also why in the script, almost all of the Zhuji Dan comes from the big sects, where is there a well-cultivated nine-leaf spiritual vein flower in an ordinary place!

It is good luck to encounter the spirit vein flower and be born on its own, and it is very likely that it is also mutilated, if it is not mutilated, wouldn't it be a brain disease to take it to refine the Zhuji Dan? If you enter the great sect, how much do you want?

Immortal Dao, the higher you go, the more concentrated your resources become, which is an obvious thing.

"Medium-grade inferior spirit strains can already help break through the realm in the early stage of foundation building."

Gu Dan didn't have too many disappointments, and when he was full of calculations, it was only eight drops of Aoki liquid.

However, Gu Dan tried to use the Aoki liquid in his body to absorb the aura, and after calculating the difference, he found that the speed at this time was only equivalent to a high-grade spiritual root with good talent.

But compared to normal practice, catalytic elixir is still earned.

"In this way, let's try to increase how much cultivation we can increase!"

With a single thought, Gu Dan gently plucked one of the leaves of the three-leaf spirit vein flower, put it in his mouth and chewed it.

On the first day, there was no bitter taste of grass, on the contrary, with a hint of sweetness, and then the pure aura burst out, baptizing Gu Dan's body.

"The effectiveness is not bad."

After tasting one leaf, Gu Dan also picked the remaining two and swallowed them all.

Suddenly, the extremely pure spiritual energy in Gu Dan's body was surging, and all the meridians in his body seemed to be filled with that pure spiritual energy, and they were pulled by the sea of qi in his dantian and merged into it.

After a while, Gu Dan faintly felt a slight bottleneck, but before he had time to think about it, the bottleneck had suddenly burst, and the aura merged into the dantian qi sea, and Gu Dan's breath rose steadily.

Seven layers of Qi training!

Late stage of Qi training!

It was only a year for him to be promoted to the sixth level of Qi Training, even if it was a true Heavenly Spirit Root, he would have to polish it for at least another year or two before he could reach the late stage of Qi training, and his real qualifications were no more than inferior Spirit Roots, and he might have to face a bottleneck in the late stage of Qi training.

However, the middle-grade and inferior three-leaf spirit vein flower, with only three leaves, saved him more than two years of penance, and what bottleneck was even less familiar, so he rushed over directly.

In this way, it seems that the elixir is much stronger than the serious cultivation.

"Yes, after all, it is a realm-breaking elixir that is useful in the early stage of foundation building, and it is normal to have this ability."

Gu Dan nodded with satisfaction, and without hesitation at the moment, he plucked the spirit vein flower and swallowed it in one gulp.

There is no taste.

I don't even feel much aura.

As soon as the flower entered its mouth, it slid into its abdomen, and finally fell on the Qihai Dantian.

The spiritual mist between the flowers reflects the spiritual energy between the qi seas, reflecting and resonating with each other, bringing Gu Dan not a sense of rapid rise in strength, but a slight discomfort.

Along with that discomfort, in the sea of qi, a little aura was stirred, separated, and thrown out of the body.

That was the aura that he had just suddenly ascended with the help of the leaves of the three-leaf spirit vein flower!

No matter how much the medicinal power is transformed, there are always some that are not suitable for the human body.

The flowers in the three-leaf spiritual vein flower do not represent the growth of cultivation, but to help people solve problems and eliminate residual troubles, even if they don't let go of themselves.

But the role of the Spirit Vein Flower is far from being the only one.

As the impurities of the aura were thrown out, the sea of qi churned and surged, and the aura that had originally expanded most of the sea of qi began to shrink gradually, slowly showing a trend of atomization!

Gu Dan's aura became more and more condensed, but the sea of qi became more and more 'empty', and finally the spiritual vein flower completely dissipated, and the aura that originally occupied most of the sea of qi could only occupy half of it, and it was all mist!

This is because he has a solid foundation and has not swallowed any elixir before.

"It deserves to be one of the main medicines of Tsukidan!"

Gu Dan was pleasantly surprised.

This step should be done slowly after practicing the ninth layer of qi, and after all the aura in the sea of qi is mist, then find a way to turn the aura into liquid.

But when the Spirit Vein Flower was practicing the seventh layer of Qi, he helped him do it first.

If it weren't for that, this elixir would not have become one of the main medicines of Tsukidan.

Gu Dan waved his hand gently, and a vine no thicker than an ordinary person's thumb appeared in his hand, swimming like a green snake, vivid, quite real, and almost nothing unusual.

And in the Qi Sea Dantian, the atomized aura is only slightly less.

"That's right, after atomizing the aura, and then casting spells, the consumption will be reduced, and the utility will also be greatly improved!"

Gu Dan smiled, and soon, his immortal Dao cultivation would also catch up with his own strength.

However, in order to avoid accidentally blowing up the cave again like the last time, it is really difficult to explain, and Gu Dan did not experiment too much.

After everything settles and the elixir is in his stomach, Gu Dan has the leisure to observe everything around him.

It is said that it is fast, but in fact, the change of the elixir also takes time, and more than three days have passed at this time, and there is no change in the cave.

Only the communication rune was constantly flickering, and Gu Dan picked it up and took a look.

Lu Yu looked for him once.

Zhuang Sheng looked for him three times.

He naturally looked at Zhuang Sheng first.

The three spiritual patterns are intertwined and turned into words.

[Still in retreat? 】

[It's a fight!] 】

【Get out of the customs quickly! 】
