After making sure that there was no danger, Nie Yuntian returned to the main hall and carefully searched ahead, the soul immortal should not take the initiative to attack him, but he still had to be careful.

The main hall is very spacious and clean, with bronze lamps standing on both sides, and the glowing gems on them illuminate the entire hall in a trance.

There seemed to be nothing left except the soul immortal at the end of the main hall, and behind the soul immortal was a whole stone wall, and there was no other way out.

He frowned slightly, his eyes searched carefully around and did not let go of any corner, suddenly his face was happy, and he walked towards the left front of the soul fairy in small steps, and behind an everlasting lamp, he picked up three black statues.

"I've finally found it!"

Nie Yuntian said excitedly, these three statues are carved with three old men of the fairy wind bones, each of them is only a foot tall but quite heavy, the whole body is pitch black, except for the head is clearly visible, the carving of other parts is extremely rough, and the lower body of the person can only be barely seen, but this does not affect it is the treasure of the synthetic aura.

This black stone is called the Star Shine Stone, which is only found in the starry sky of the universe, has scarce reserves and is expensive, and it is the only ore that can collect the power of the wish on its own and use it to synthesize the aura.

These three old men can be carved into statues and enshrined here, most of them are the founding patriarchs of the Tianya Dao Sect or extremely accomplished people, but they don't know whether they are alive or dead in the catastrophe that destroyed the sect.

Holding the three statues, Nie Yuntian looked at them and put away the largest one among them, and the remaining two took out a stone slab and enshrined it on it.

A piece of Star Shine Stone is enough for him, if he takes it all, without the replenishment of the aura, the aura in the dojo space will become less and less, once the consumption of the Xuanwu True Spirit Array cannot be maintained, the entire dojo space will be annihilated in that space storm, and it will be gone.

He has received so much of their grace, and if he destroys their home, it is really a little unreasonable, well, in fact, he is afraid that the soul fairy will find trouble with him after waking up, because even a space storm may not be able to destroy him.

Bowing to the two statues is a thank you for their kindness.

After glancing at the soul immortal, Nie Yuntian walked out of the main hall, and there were no other treasures in it.

Back in the square, Nie Yuntian did not leave immediately, but took out his Spirit Gathering Array Disk, and spread them evenly around the square, in the center of the square, he took a flower pot, in which was planted a small grass with ten leaves, which was one of the four unknown elixirs taken from the blood pool in the center of the small world.

To be precise, it is called the Immortal Spirit Grass, which is a variant of the ninth-order vitality grass, and the vitality contained in it is more than dozens of times more powerful than the ninth-order vitality grass in its complete state.

It is a kind of superb elixir that can really live the flesh and bones of people, as long as there is still a trace of qi hanging, it will never die, of course, it is limited to cultivators, and the effect on immortals is greatly reduced.

And in addition to that, it is also a necessary elixir for cultivating a Thousand Refining Body, without it, don't delusionally dream of reaching the highest level of the Thousand Refining Body Realm.

The yield of fairy spirit grass is extremely low, and it is an extremely rare treasure even in the Flood Realm, because its mutation rate is extremely low, to an outrageous level.

Even if the ninth-order vitality grass is the ninth-order elixir with the shortest growth cycle, it takes a thousand years to mature, and only a very few plants in the mature ninth-order vitality can mutate into the fairy spirit grass, if there is no deep foundation, ordinary forces will not be able to cultivate the fairy spirit grass.

Lin Tao didn't know if the four plants were cultivated by himself or snatched by him, in his mind, it was probably the latter, and these four plants were also like those ninth-order vitality grasses, which had lost a lot of medicinal power in the long years, but as long as the spiritual energy above the top grade was enough, it could return to its original quality.

It is only absorbed by the upper-grade and above-grade aura, such as those middle- and lower-grade mixed auras on the periphery, but Nie Yuntian has no intention of letting it go, and has his own ninth-order angry grass to absorb it.

After placing the fairy spirit grass, Nie Yuntian returned to the outside along the tunnel, preparing for such a long time that it was time to go to the alchemy.

Returning to the Dantang of the Tianya Dao Sect again, this place has changed greatly, the place where the original earth fire exit was dug into a big pit, and a new earth fire exit was built at the bottom of the pit, and the rolling fire waves gushed out from it, and the stones next to the burning were shining red.

After descending to the bottom of the pit, Nie Yuntian returned to the small world, and he had to wait, waiting for those wandering spirits to pass before he could refine the pill.

This area already belongs to the middle and periphery, and the frequency of the ghost patrol is not as large as the inner perimeter, and the soul general-level spirit can only be encountered again for more than an hour.

While waiting, Nie Yuntian went to prepare the elixir for refining the Gathering Spirit Pill, refining the Gathering Spirit Pill required a total of six elixirs, except for the Xiaoye Purple Sect, which was a second-order top-level elixir, the other five auxiliary medicines were only first-order.

It is not difficult to refine the five kinds of auxiliary medicines, how to say that he is also a first-grade peak alchemist, it is not difficult for him, the difficulty is to refine the second-order top elixir Xiaoye Zigang and fuse the five auxiliary medicines into it, and condense it into a pill.

Fortunately, there was an earth fire here, and his divine thoughts had also strengthened a lot after devouring Lin Tao's memory, barely reaching the level of refining the small leaf purple former, making it possible for him to refine the Gathering Spirit Pill with the method of practice makes perfect.

However, he didn't plan to refine them together, even if he had a half-step cultivation of Gathering Spirits, he couldn't support the refining of a furnace of Gathering Spirit Pills.

He split the general steps into two steps, refining the small leaf purple and the other five elixirs respectively, and finally fusing the two elixirs together, although doing so would waste a lot of elixirs, but who made him have so many elixirs, well, it's so capricious.

Not long after, after a soul general-level wandering soul patrolled here, Nie Yuntian jumped out and hurried the medicinal liquid he had refined.

Before the other soul came here, he had refined more than thirty copies of the fusion of the five auxiliary medicines, and the efficiency was very good.

However, Lun was much slower when he arrived at Xiaoye Zijiao, the second-order top-level elixir was not so easy to refine, and he could only refine one plant in an hour, Nie Yuntian was not in a hurry, anyway, he had enough time.

Three days later, next to the crater, Nie Yuntian sat quietly on the ground, adjusting himself to the peak state, and only in this way could he succeed.

On his left hand side by side were two rows of Dan bottles, one row was the liquid of the auxiliary medicine, and the other row was the liquid of the small leaf purple plant.

The Red Flame Furnace was already warm, and with a Dan bottle in each hand, he quickly poured the medicinal liquid inside into the Dan Furnace, and at the same time, Shen Nian also carefully controlled the fusion of the two.

"Phew!"

With a bang, before the two streams of liquid medicine could fuse, they turned into two puffs of smoke, one purple and one green, and rose out.

Nie Yuntian was not surprised, and after cleaning up the residue, he continued to pick up the Dan bottles next to him, and poured them into the Dan furnace to try to fuse.

Soon, the thirty-five parts of the spiritual liquid all turned into smoke, but Nie Yuntian still learned some lessons from the failure.

Three days, six days, nine days......

A month passed like this, and after consuming a large amount of elixir, Nie Yuntian finally succeeded once, well, practice makes perfect, and the ancients did not deceive me.

Looking at the pitted purple pill in his hand, Nie Yuntian nodded with satisfaction, and continued refining it after solemnly putting it away.

The medicinal effect of the Gathering Spirit Pill refined by himself is definitely not as good as that refined by those senior alchemists, but it doesn't matter, the amount is enough to make up for the gap, and it will definitely be able to break through the last dantian barrier and successfully condense the spiritual liquid to advance to the Gathering Spirit Realm.

Two more days later, until more than twenty Gathering Spirit Pills were refined, Nie Yuntian called it a short end, and with the Gathering Spirit Pill, he returned to the forbidden place in the center of the dojo space, and the breakthrough was naturally here.

After more than a month of absorption, the top-grade spiritual energy accumulated in the dojo space for an unknown number of years has been absorbed by the fairy spirit grass, although it has not been able to restore the fairy spirit grass completely, but it has also reached seven or eight percent, and it is completely easy to save the lives of monks below the fairy spirit realm.

The consumption of high-grade spiritual energy was exhausted, and the surrounding middle-grade and lower-grade spiritual energy was naturally replenished, making this a veritable cultivation treasure land.

Sitting in the center of the square, Nie Yuntian meditated for two days and suddenly opened his eyes, his eyes were full of scorching light, which was about to break through:

"Gathering Spirits!"

Immediately, a handful of Gathering Spirit Pill was poured into the mouth, and the calm dantian immediately became restless, and the surging spiritual power formed waves to impact the last dantian barrier with all its might.

"Boom, boom, boom......"

Soon, the last dantian barrier was also shattered in the roar, and Nie Yuntian's dantian finally formed a complete and unique dantian!

The next step is to condense the spiritual liquid, advance to the Gathering Spirit Realm, and go one step further on the path of the Emperor Immortal!
