After successfully channeling the qi of earth fire into his body, Yu Lie suddenly felt that his whole body was immersed in magma, and his whole body was about to burst.

However, he calmed down and made the heat surge towards the dantian as much as possible, locking the pores all over his body, and keeping the heat in his body as much as possible.

After another moment of recuperation, Yu Liefang opened his eyes, and the joy in his eyes was strong.

He stroked the position of his lower dantian, and suddenly felt as if there was a furnace placed in it.

After successfully inducing fire into the body, Yu Lie only needed to replenish the earth fire qi incorporated in the dantian from time to time, and the true qi in his body would be purified by itself every time it poured through the lower dantian, which was very convenient.

Yu Lie pinched his fingers and found that with his Taoism and foundation, with the help of the Qi of Earth and Fire, he could completely polish his true qi within a month, so that he could carry out the "Change of Water and Fire".

Jumping out of the tent happily, Yu Lie paced to the fire pool, and suddenly his eyes flickered again, looking at the magma in the fire pool.

I saw that he stretched out his hand, and the yellow gourd placed on the edge of the fire pool suddenly fell into his hands.

Then Yu Lie got into the blood tent again and started another job of his own.

This time he entered the alchemy room for retreat, refining the body with earth fire and polishing the true qi was the first task, but in addition, Yu Lie also planned a task for himself.

After entering the tent, he took out the bronze wine glass, placed it in the thick isolation mist, and then held the yellow gourd, tilted the mouth, and poured it into the bronze wine cup.

Streams of magma suddenly erupted from the mouth of the gourd, but when they came into contact with the small bronze wine glass, they shrank in an instant, and the strands of magma turned into silk threads, swirling in the wine glass.

After coming into contact with the special liquid in the wine glass, the earthfire magma did not solidify and evaporate, but remained in a molten state, as if the inside of the wine glass was also very hot.

Yu Lie took a breath and poured the entire gourd's earth fire magma into the wine glass, a room-sized magma liquid, only the size of a sugar cube in the cup, and it was no problem to continue to fill five or six squares.

So Yu Lie hurriedly walked out of the tent again, intending to put the yellow gourd under the golden iron dragon head and collect the earth fire magma again.

However, halfway through, his body paused slightly, stopped his movements, and instead paced a few laps in the alchemy room, and suddenly moved the tent to its position, so that the mist inside enveloped a golden iron dragon head.

This kept the dragon's head in the mist, presumably to prevent anyone from seeing that Yu Lie was collecting too much magma too often and causing him to die.

In the following time, Yu Lie continued to transfer the earth fire magma into the bronze wine cup, waiting for the earth fire magma to be completely purified by the bronze wine cup and turned into a pure fire aura!

This fire aura is another major goal of Yu Lie's trip.

Wine glasses can transform spirits, and earth fire magma is rare, it comes from below the earth's crust, although the inner aura is not as good as the special spiritual liquid spiritual water, but it can also be regarded as full of spiritual power.

Yu Lie estimated that if the bronze wine cup could successfully purify the earthfire magma, then he would undoubtedly have to harvest a bunch of aura out of thin air!

After pouring the earth fire magma into the wine glass for a long time, seeing that the wine in the wine glass was finally about to be level with the surface of the glass, Yu Lie stopped, and then looked at the inside of the wine glass with flickering eyes.

"Purifying the aura from the earth-fire magma, I'm afraid that no one in the world will have this idle time at all, and I can do it. It's just that I don't know how much aura this whole cup of magma can refine......

Yu Lie looked forward to it, staring at the bronze wine glass without blinking.

The wine glass did not disappoint Yu Lie, even if the glass was full of magma, the amount was extremely large, but under the effect of the magical liquor, it was still slowly shrinking at a speed visible to the naked eye.

The height of the transparent liquor in the glass also slowly decreases.

After descending to a certain level, Yu Lie's mouth let out a surprised voice: "Huh! ”

I saw that after the earth fire magma was condensed to a certain extent, it did not change to the aura, or rather, it did not directly begin to transform into a spirit, but began to evolve into another mineral.

The surface of this object is a kind of glazed feeling, covered in the earth-fire magma, and crystallized layer by layer.

This surprised Yu Lie: "The fire magma here can form another product after purification, could it be that it is about to form a spirit stone?" ”

This thought jumped out, making Yu Lie's mind pound for a while.

If this is the case, doesn't that prove that he may be able to artificially create spirit stones by taking earth fire magma in the future?

In this way, it can not only facilitate his cultivation, but also can be cut and directly traded for use.

It's just that in Yu Lie's expectant gaze, the crystallized magma is still shrinking, shrinking from the size of a sugar cube in a cup to the size of a sesame seed in one breath.

Its color is also becoming more and more pure, exquisite, and it looks quite hard, and the aura is also more and more abundant.

However, this appearance fell in Yu Lie's eyes, making his expression a little suspicious, because the deeply crystallized magma was less and less like a spirit stone.

Although the spirit stone is a general name, there are many specific categories according to the different quality of the stone. But what is worthy of the name of the spirit stone, its color is warm, and the aura is quite stable in it, and it will not easily escape.

No matter how rich the aura is, the aura ore that can escape too much is generally not called a spirit stone, and it will not circulate to the market, so it is inconvenient to use it as a transaction.

Yu Lie waited patiently for a long time, and when he saw that the sesame seed-sized thing in the cup was about to shrink, he quickly stretched out his hand, and his true qi was running, and he wanted to move it out.

But before his fingers touched, Yu Lie's complexion changed suddenly, and he exclaimed in his heart: "Not good"!

He quickly withdrew his hand, and then looked at the sesame seed-sized crystal in the cup with a pale face.

At the moment when it was within reach, Yu Lie sensed a violent fire spirit qi in the cup through his true qi. If it weren't for the magical detaining effect of the bronze wine glass, this thing would have exploded long ago.

Therefore, Yu Lie's courage trembled at that time, and he quickly dispelled the idea of taking this thing out.

Otherwise, as soon as the crystal comes out, it will explode immediately! Let him die without a body.

Yu Lie had to stare at the crystal, which was continuously purified by the wine glass, and after being so pure that it could not be increased, it cracked like a bubble, and completely turned into an aura, which remained in the cup and had no other effect.

As it cracked, the crystal flickered violently, and a small ethereal red-gold flame rose.

After watching the whole process of the earth fire magma being purified, Yu Lie's eyes showed a sudden look, and he muttered in his heart:

"It turned out to be this kind of product, Earth Fire Essence Crystal!"

Earth Fire Essence Crystal, a natural product of Earth Fire Magma, this thing is similar to a spirit stone, but the texture is extremely strong, if it is used as a stone knife, the sharpness is directly comparable to gold and iron. It's just that this thing is not tough, so it is not used to refine magic weapons, and is often used as ore, or alchemy, or as a material for drawing talismans.

In addition to being used to refine things, this thing also has another nickname: "Earth Fire Essence Charcoal"!

This object is the essence of the earth fire, and when placed under the Dan furnace, it can release a huge amount of heat without igniting it, as if the earth fire is springing out of thin air.

Therefore, this Earth Fire Essence Crystal is a good thing that blindly allows Taoists to use Earth Fire Alchemy Pills everywhere regardless of time and place, and the price is not bad, and it is often used only by Taoist officials and above.

And for an eight-rank Taoist like Yu Lie, in addition to being used for alchemy, this thing actually has a greater role.

In the tent, he stroked the bronze wine glass, his eyes lit up: "It seems that this Earth Fire Alchemy Room is really not wrong, and the biggest hole card for participating in the Dao Palace assessment this time is also available, so there is no need to go out of your way to buy it!" ”

The Earth Fire Essence Crystal is something that can release the Earth Fire for alchemy, in other words, if the Taoist has the right means, he can actually release the Earth Fire to resist the enemy when he is in battle.

The killing spell that Yu Lie is good at is the fire method, and the essence crystal falls into his hands, and it can be blessed on the fire method by holding it, so that the power and range of the poisonous flame will be increased by three or five times, or even ten times!

Looking forward to it in his heart, Yu Lie immediately slowly extradited the completely purified aura from the wine glass and incorporated it into several spirit gathering charms, which was convenient for his personal cultivation in the future.

Then he put the earth fire magma in the wine glass, and began to patiently ponder the degree of purification.

Earth Fire Essence Crystals are actually not uncommon under the earth's crust, on the contrary, their number is huge. The reason why it is expensive, Taoists mostly use it for emergency use, in addition to the difficulty of mining, more importantly, if this thing is used as a cargo, the purity requirements for it are very strict.

The purity of the finished product should not be too low, otherwise it will not form a ground fire, or when it is turned into a ground fire, it is easy to produce a lot of poisonous smoke, which is not only wasteful, but also unstable in nature, and is not suitable for alchemy.

In the same way, it should not be too pure.

Otherwise, once it is out of the special environment under the earth's crust, the slightest wind and grass will blow, and the spar itself will explode violently, and the Taoist will not be able to use it but will hurt himself.

Yu Lie heard that there is a secret method, which can re-refine all kinds of earth fire spars and artificially blend the concentration, but this method is not perfect, it is an increase in the cost of refining on top of the high price of the spar, and there are other shortcomings, so it is not popular.

However, for Yu Lie, if he wants to grasp the concentration of the spar, it is very easy, and he only needs to divide it intermittently according to the soaking time.

With several years of experience in using wine glasses, Yu Lie didn't spend much effort to figure out the appropriate purity of the Earth Fire Essence Crystal. Immediately, he began to grab the earthfire magma and purify it into the earthfire essence crystal.

In order to save time, Yu Lie simply expanded the mist spell to the maximum, enveloping the three golden iron dragon heads in it, so as to facilitate the extradition of earth fire magma.

When the work of purifying the refined crystals was on the right track, Yu Lie found that there was still more than half a day before the deadline for using the earth fire.

So in the spirit of not wasting it, he took out three wooden branches from his sleeve.

The appearance of the three branches looked unremarkable, but when it fell into the hand, it was as heavy as copper and iron of the same size. Yu Lie picked up two branches and touched each other, which also made a crisp sound similar to metal.

The source of these three branches is none other than that of the black shou.

A few days ago, when he was chopping wood and refining pills for the other party, Yu Lie secretly accepted a little, and he didn't dare to take more, he only took these three, each of which was the size and thickness of a baby's flesh arm, and fell into the huge demon body of Shouwu's worship, which was only as big as a small fingernail.

In addition to the three branches, Yu Lie pulled out of his sleeve again, and several porcelain vases appeared. He pulled the cork, and immediately a strange smell appeared around him.

The liquid in the porcelain plate is golden-red, and it is also the blood that splattered out when Shou Wu worshiped his body at that time.

Yu Lie sat in front of the earth fire magma pool, his true qi was swallowed, the magic trick in his hand was pinched, and a branch placed on his knees immediately floated up, falling on the magma pool, and clusters of flames surrounded him.

The golden-red liquid in the porcelain plate next to it is also turned into silk threads, cemented into the branches.

Then there were runes one after another, which were copied by Yu Lie on the branches, and he used the wind blade to gradually cut the entire branch into the shape of a small flying sword.

This move in front of Huochi was the branch and blood that Yu Lie was enshrined in Shou Wu to refine a new grass and tree swimming sword.

The two main raw materials of sword refining are of the same origin and homogeneity, and in just half an hour, the grass and wood swimming sword has already taken shape, and it can slowly swim beside Yu Lie.

Its color is completely different from the previous ones, and the sword reveals a green steel color up and down, not like grass and trees, but more similar to copper and iron.

The re-refined Swimming Sword is so fire-resistant, it is undoubtedly more suitable for Yu Lie to bless the two techniques of wind and fire on it, and use it superimposed.

The three-day deadline is approaching, and there is still an hour left before the customs exit.

Yu Lie in the Dan room looked tired, but he looked at his side with great joy, and the three green steel swords were all formed, slowly rising and falling in front of him.

After looking at it for a moment, Yu Lie waved his sleeves and put one of them into the belly of the blood clam as a backup, and the other two were hidden in the two sleeves.

He also pinched the pitcher plant pocket inside his sleeve robe, and his eyes were even more excited!

Because of this retreat in the Earth Fire Dan Room, Yu Lie has gained a lot.

In addition to a dozen or so spirit stones that were infected with the qi of earth fire, as well as a gourd of magma, and three green steel grass swords, there were also five whole pieces of earth fire essence crystals, which were prepared by him and included in his pocket!

Yu Lie estimated that if these five pieces of Earth Fire Essence Crystals turned into Earth Fire, they would be enough to burn uninterrupted for two or three months.

If you sell it, you may be able to exchange it for more than a thousand spirit stones. However, the origin of this item is unknown, and he does not dare to sell it at will, so it is better to use it privately.
