Now, Jiang Chen was holding several demon pills in his hand, and he was observing how many Yuan Essences could be extracted inside, and on the stone platform next to him, there were also a large number of Demon Pills and a few bottles used to hold Yuan Essence.

In the past few days, he has been seriously looking at the jade slip of the "Demon Pill Yuan Essence Extraction Secret Technique" copied from the study of the Demon Soul Ancestor, and read it carefully, his face showing a cautious expression.

In fact, he has read this "Demon Pill Yuan Essence Refining Secret Technique" many times. I have long been able to recite it backwards. It's just that although there are many demon pills, there are very few yuan essences in each demon pill, in order to avoid waste, he can't be cautious and try to avoid any omissions.

Originally, they planned to use one hour a day to extract the essence of the yuan. However, what Jiang Chen and the others didn't expect was that this ice bird was very fast, and it was not a big problem to kill hundreds of them in half a day. And it's much more cumbersome to refine.

Now the demon pills in the stone room are piled up, but the progress of the Yuan Essence extraction is slow and slow. Therefore, after some discussion, the extraction of the essence of these demon pills was handed over to Jiang Chen, who had experience in extraction, to deal with. He didn't participate in killing the ice bird for the time being.

His place was filled by the queen ant. Anyway, the queen ant doesn't need to rest, as long as there is always the flesh and blood of the demon beast devouring, then she and her black devouring ant can maintain the spiritual power in the body and keep killing.

Jiang Chen finished reading the "Demon Pill Yuan Essence Extraction Secret Technique" again, and after confirming that it was correct, he took out a silver-white demon pill from the demon pill pile on the table and began to refine it. Bai Plating means that hey, the eye brother closes the mouth and heart chapter

This Ice Bird's Demon Pill was suspended in mid-air, its whole body was silvery-white, crystal clear, and shrouded in a layer of white light.

Jiang Chen quickly recited the incantation, casting this extraction secret technique. After half an hour, this demon pill came out with steaming heat, forced by a powerful mana, and then gradually dimmed and dried up, until it could no longer squeeze out any spiritual energy.

But at the same time, a very dazzling silvery-white liquid appeared above it, extremely tiny, and the vitality contained was amazing.

This is the essence of the Ice Bird!

Jiang Chen was overjoyed when he saw this, and he made a move. A small porcelain bottle was used to collect the little bit of silver-white liquid. After succeeding in his initial attempt, he relented and continued to refine the remaining Ice Bird Demon Pill.

At first he was very slow, but as he got used to it, his progress increased. It didn't take long for him to put Xiao Qian on the table in a pile, about eighty demon pills were refined, and he collected a small bottle of very pure Ice Bird Yuan Essence.

This small vial of Yuan Jing seems to have an extremely strong spirituality and an unusually strong fierce aura.

The breath of this primordial essence is directly related to the nature of the ice bird. It was the essence of the Yuan Qi extracted from dozens of Ice Bird Demon Pills of the fourth to fifth order ranks, and the fierce qi in it was naturally extremely strong.

Jiang Chen looked at this small bottle of white Yuan Jing, and he was also thinking in his heart: a fourth-order Ice Bird Demon Pill would be sold in the market. The price will not be less than five hundred spirit stones. He has already refined more than eighty demon pills, that is, more than forty thousand spirit stones.

So many spirit stones are enough to buy a few very good high-level magic weapons. But now, it has all been refined into this small vial of Yuan Jing, and then used to refine the Yuan Shen magic weapon. I don't know if it's worth it.

Jiang Chen held the small porcelain vase and smiled helplessly. Things have come to this point. He and Wang Tingting, Lin Yusheng, Shui Youning, and Shui Yuening had no way out, and they had to collect all the Yuan Essence to refine their Yuan Shen magic weapons, so as not to waste their tremendous efforts in the past few months.

Each of the four women had a top-level magic weapon that was ready to be used as a Yuan Shen magic weapon, and Jiang Chen planned to use the Ten Ghost Banners to use his Yuan Shen magic weapon.

If you want to refine all five magic weapons into a Yuan Shen magic weapon, you need a lot of Yuan essence. The small bottle of Ice Bird Yuan Essence that Jiang Chen worked hard to refine could only be said to be a drop in the bucket. Therefore, he still has to redouble his efforts to achieve his dream of owning the Yuan Shen magic weapon for himself and for the four girls.

Theoretically, the demon pills of seventh-ninth order demon beasts can extract more yuan essence. It is generally equivalent to the demon beasts of the human Jindan stage monk-level, and the demon pills taken out of their bodies can be refined into one yuan essence.

And the fourth- to sixth-order demon beasts are equivalent to the demon beasts of the human foundation building period monk-level demon beasts, and their demon pills can only refine one-fifth or even one-sixth of the elemental essence at most, and the quality is also worse than the elemental essence refined by the seventh-ninth order demon beasts. According to Shui Yuening's estimate, I'm afraid it takes ten Ice Bird's Demon Pills to be able to extract the One Yuan Essence from them.

Therefore, the more ice birds they killed, the greater the chance of getting the demon pill, and the more Yuan Jing they could refine at the same time.

Moreover, in order to ensure the purity of the Yuan Essence, and it is best to be the Inner Dan of the same kind of demon beast, so that the breath of the Yuan Jing can be very pure, and the refined Yuan Shen magic weapon is naturally better.

Since Jiang Chen and the others found out that there were hundreds of thousands of huge ice birds here, they would naturally not let it go, hundreds of thousands of fourth- to fifth-order ice birds were estimated to be able to give him tens of thousands of demon pills.

Although each demon pill has a small amount of Yuan Essence, the number is extremely large, and after accumulating a lot, the Yuan Essence is still enough for him and the four women to refine the Yuan Shen magic weapon.

The five of them took advantage of the narrow entrance passage of this cave, and stuck in place, hunting and killing the ice birds that rushed into the cave day and night, and the divine sense controlled all kinds of magic weapons, swords, blades, ghost claws, etc., all mercilessly strangled the past, and every attack could cut down an ice bird. Sometimes even two were hacked to death with a single knife......

The ice birds in the cave gradually piled up like a mountain. Although Xiao Qian devoured a lot, there were still many remaining corpses.

Originally, the four girls were worried about what to do with these corpses, but Jiang Chen said with a big grin: "Leave it all to me!" ”

With a wave of his hand, he summoned the Black Eater Queen, and let it and its men devour the corpses of these ice birds, and he did not let go of the souls of those ice birds, and included them in the Ten Ghost Banners.

Although the quality of these souls is not high, and the attack power is low, it is not bad to be cannon fodder, and after the Ten Ghost Banners have absorbed a large number of demon beast souls, their energy and quality have also increased a lot. Far stronger than when Jiang Chen first got it, the gloss and power were much stronger.

It didn't take long for Jiang Chen to ask the fourth girl for a leave. Because his Ten Ghost Banners after inhaling a large number of Ice Bird Souls. It has reached the limit of its capacity, and if it is not re-cultivated and upgraded to a hundred ghost flags, it can no longer be loaded into the soul.

Originally, Jiang Chen had long wanted to refine the Ten Ghost Flags again, but he didn't have so many souls in the foundation building period. Although he could also use a first-order to third-order demon beasts, or the soul of a monk at the level of the Qi refining period, it was only in that way that the power and efficacy of the Hundred Ghost Banner after the promotion would be reduced a lot.

Therefore, Jiang Chen has been holding either or not refining. Or just sacrifice the most powerful idea. That's why the re-sacrifice of his banner has been delayed to this day.

Now, in this glacial crestic, there are a large number of ice birds equivalent to the foundation building period, and their combat effectiveness is not strong, and they can be hunted in large numbers. You can follow the highest standards of Hyakkiba. Use the soul sacrifice of the nine hundred and ninety-nine foundation building stage levels to raise this banner to the strongest level.

However, Jiang Chen did not immediately start the cultivation of the Hundred Ghost Flags, but first took out the jade slip of the "Soul Imperial Technique", carefully read it with his divine sense, and it looked like it was more than a week.

The reason why it has been delayed for so long is naturally because the refining of the Hundred Soul Banner with the soul of the beast is quite different from the method of sacrificing the soul of a monk recorded in the "Soul Imperial Technique". And Jiang Chen had no one around him to ask for advice. I can only study it slowly on my own.

A week is not a long time. Every day, except for the necessary cultivation and the hunting time for ice birds at the entrance of the cave, Jiang Chen spent all his energy on the sacrificial scrutiny of the Hundred Ghost Flags.

"It seems that my previous idea should be feasible." Jiang Chen put down the jade slip in his hand, and in the past week, he had already memorized the method of sacrificial refining of the Hundred Ghost Banners backwards.

The sacrifice of this hundred ghost flags. According to the Jade Slip of the Imperial Soul Technique, the most difficult point is that a large number of high-level souls are required. It's just that the most difficult point now is for Jiang Chen. Instead, it's the easiest.

Secondly, it is the selection of materials. The materials required to refine the Hyakki Banner are relatively expensive. But this is for Jiang Chen today. Not so much. After all, he had looted a large number of rare refining materials in the cave of the queen ant before.

And in addition to him, the other four women also carried a lot of materials on their bodies, mainly for the construction of magic circles, talismans and alchemy. Although most of these materials have nothing to do with Hyakkiba. But there are also many materials that can be used universally. Therefore, Jiang Chen still easily gathered all the materials for re-refining the Hundred Ghost Banners.

Now, he first took out a Yin Spirit Bead. This thing is the most yin thing. Contains a large amount of Yin spiritual power. Back then, in the Yin Spirit Pool, he relied on absorbing the Yin Spirit Power in this Yin Spirit Bead to cultivate and break through two layers in a row.

Moreover, this Yin Spirit Bead can also be used to replenish the Yin Spirit Power in the body, and the effect is better than that of the Spirit Stone.

At the same time, the Yin spiritual power within it is also more suitable for ghost path cultivators, and it is not as violent as the spiritual power in ordinary spirit stones. On the market, a good Yin Spirit Bead is also sold for one or two thousand spirit stones.

Jiang Chen used it to refine the Hundred Ghost Banners, which was the best auxiliary material that could be found within his ability.

As for the main material of the Hundred Ghost Flags, Jiang Chen planned to use the Erosion Shadow Wood.

This is also a very precious refining material, especially for ghost cultivators, it is extremely rare. Jiang Chen had only seen Uncle Kun take it out once in the Heavenly Workshop, and asked about the price at that time, 50,000 spirit stones per catty. This price would hurt even a Jindan stage monk. However, Jiang Chen planned to use ten catties of eroded wood to sacrifice.

If Zixi knew about this, he would definitely scold him for being extravagant and wasteful. The Hyakki Banner is refined with such a precious material, so what will the Thousand Ghost Banner use in the future?

However, Jiang Chen didn't think about it so much at all, he fished out a large amount of refining materials, and he was worried that he didn't know how to use it. I felt it was a pity to sell it, so I simply took it to my own sacrifice.

After checking all the refining materials and confirming that there were no quality problems, Jiang Chen came to the bottom of the ice cave and began the sacrificial practice of this banner flag.

He took out all the materials he needed and put them away. Then he swung the seven-star knife and slashed violently into the ground.

I heard a loud "bang", and sand and stones suddenly splashed out of the ground.

A moment later, a large hole in the ground erupted from it, and a large stream of bright red flames erupted from it.

The reason why Jiang Chen deliberately chose this cave before was because he found that under this rift, there was the existence of earth fire lava, although these earth fires could not be spewed out of the ground due to the cover of glaciers, but as long as they opened a gap, they could use earth fire alchemy and refining weapons.

Seeing that the earth fire really came out, Jiang Chen was also overjoyed, and quickly took out a pile of dark iron from the storage bag, cast it into the shape of a dragon's head, covered it with the ground fire gap, and added a rotatable switch on it to adjust the amount of fire.

After finishing the work, Jiang Chen held the switch in his left hand and rotated it gently, only to see that the dragon's head soon erupted with bright red flames, and the amount of fire could be adjusted according to his needs.

A hint of joy flashed on Jiang Chen's face, and then he put the Eroded Wood on top of the dragon's head and began to bake, and the progress was quite smooth.

Seeing that everything was normal, the Eroded Ghost Wood was beginning to melt and deform according to his thoughts, Jiang Chen smiled slightly, and added some auxiliary materials such as the Millennium Xuanjin and the Ghost Stone, which were also superlative materials, and they were enough to refine the Thousand Ghost Banners. Jiang Chen, on the other hand, used them to refine the Hundred Ghost Banners. I don't know how many ghost monks will scold him for being a loser.

The time of the day was fleeting, Jiang Chen turned his right hand slightly, closed the dragon's head, and the earth fire also stopped erupting. The temperature in the room immediately returned to its previous coldness.

At this time, in front of him, more than a dozen colorful liquid balls appeared. These are formed after various main and auxiliary materials are melted by the ground fire.

Jiang Chen's face showed a solemn expression, there was no difficulty in refining the materials in front of him, and now it was only the most critical moment, and it could even be said that victory or defeat was in one fell swoop.
