Lu Buqi will stay by the side, waiting for the good news from the two, but he will not wait stupidly, he still has something to do.

"Elma, I'm going to start alchemy, if I suddenly disappear, it's because I've entered a small space to protect the pill, you don't have to make a fuss!" Lu Buqi reminded Irma first, and then Lu Buqi had to make preparations for alchemy.

Irma nodded, and didn't ask anything, just expectantly planning to appreciate Lu Bu's alchemy,

Lu Buqi did not directly enter the Miaoluo Water Prison, because refining the Nine Transformations back to the Heavenly Pill was a long-term process, and it was impossible for the Burning Flame to be able to support the Miaoluo Water Hell for so long.

Miaoluo Water Hell should be used at critical moments.

"Human cub, you can refine it with confidence, in the root of life to protect this land of good luck, coupled with the existence of Miaoluo Water Hell, the refining power of the Nine Turning Heavenly Pill is more than ninety percent nine. Burning cheered Lu Buqi up: "Unless that Yunqin girl's fate is really like this, it shouldn't fail." ”

Lu Buqi nodded heavily, he didn't believe that he would fail, but he definitely wouldn't be careless.

Even if there is a 10% success rate in alchemy this time, it is up to the alchemist himself to make no mistakes, if the basic steps and principles of alchemy are wrong, then what kind of objective conditions will not help.

Lu Buqi didn't directly pull out the Xianyou Ding, and then threw the materials into it in one go, even if it was refining some low-level basic pills, Lu Buqi would not be so hasty, every time he would sort out the materials very seriously.

This time it is even more impossible to be an exception, Lu Buqi must make himself make zero mistakes, after all, most of these materials can almost be said to be unique, once they fail, although they are not without a chance, I am afraid that they will have to wait for a long time, and it may even take hundreds of years before it is possible to collect them again.

Let's see how magical it is that even Danhuang Chi Zhonglin has not been able to collect all the materials, and it should be regarded as gaining some knowledge.

The first is the tenth-order Xuanzhu, which is not unusual for Lu Buqi, who now has the spirit beads, but it is relatively rare, because there may be a lot of tenth-order Xuanzhu in this shijie, but there are really not many of them jumping around, after all, the Xuanbeasts at this stage are basically ready to sprint the spirit beasts.

Blood ginseng is a very common herb, and even ordinary people will use it in some medicines. However, the nine-leaf blood ginseng is the rarest elixir in the world to invigorate blood and comb essence, because if you want to grow to nine leaves, you need to grow for at least nine hundred years.

Poria cocos is also a very common herb, but like a spirit beast, Poria cocos with eight tails is a rare and incomparably nourishing medicine. When used directly for medicine, it can also prolong life and even increase longevity.

Ganoderma lucidum is also not rare, but the seven-faced ghost mushroom is undoubtedly a rare super-grade elixir in the world, even if it is a monk, countless people have never seen this kind of thing. This seven-faced ghost mushroom, it is said that even if it is a raw clothes, it can stabilize people's spirits and prevent them from going crazy in practice.

Purple potato, sweet potato, white potato, potato...... These things are just ordinary people's chewing grains, but Liuhe potatoes have the most earthy earthy yellow skin, but have the most crystalline and colorful fleshy magical potatoes, and some people even say that if you eat a bite, you will live for ten years.

Poisonous beast gall is not uncommon, just kill a snake and slaughter a toad, I'm afraid you can get one. However, the spirit gall of the five poisonous beasts can only be obtained by killing the spirit beasts and the five poisonous beasts.

The most rare thing is not only because the Five Poisonous Beasts are spirit beasts, but also because the Five Poisonous Beasts are very timid, and any too fierce battle may scare its guts, so to obtain the spirit gall of the Five Poisonous Beasts, the most Haode method is to kill the Five Poisonous Beasts in seconds. But to kill the spirit beast in seconds, how powerful a person does this have to be? This is also the reason why Lu Buqi was very puzzled at the beginning, that snake demon actually had the spirit gall of the five poisonous beasts in his hands.

The four-leaf clover and the three-born flower, these two are not medicinal spirit grasses themselves, but functional spirit grasses.

The effect of the four-leaf clover is said to bring people good luck against the sky, people who eat the four-leaf clover, in a certain period of time the character will skyrocket, go everything smoothly, with a "scientific" explanation is to improve people's luck.

It is said that after eating Sansheng flowers, within a certain period of time, confessing or making requests to anyone, the other party will accept them unconditionally, and will not change their minds about their three lives.

If it is said that among these materials in the Nine Transformations Back to the Heavenly Pill, there is only one material that has the possibility of artificial division, and that is Yin and Yang blood. When Lu Buqi obtained the Yin and Yang blood, Li Tian and the Demon Soul Fish Intestine analyzed its special preparation and ingredients, and found that it was actually ninety percent similar to the blood on Lu Buqi's body.

In other words, in fact, the blood on Lu Buqi's body has also become yin and yang blood, because he took the thousand-year-old Yang Que and took the Innate Pure Yin Wuji Pill refined by Wang Shuangqiao sacrificing his life.

In Danhuang Chi Zhonglin's research, he believed that yin and yang blood was the blood of a person born with a body constitution that was half yin and half yang. But he searched all his life, but he didn't find such a person.

The effect of this kind of blood is said to be able to make up for congenital infertility, nourish yin and nourish the kidneys, and more mysteriously, it can make people communicate yin and yang, and talk to the dead.

If you want to say that the most rare and precious, it must belong to the Climbing Heaven Fruit and the Earth Vein Spirit Vine. One is said to be able to climb directly to the sky, and if there is a person with great perseverance, climb up along the climbing vine, can climb to the outside of the sky, and be a living immortal. The other is said to be comparable to hell, and if you dig along its vine veins, you can dig out all the places where the soul belongs.

Of course, these are said to be legends, after all, no one has ever done these two things, but these two kinds of spiritual grass are known as the best of heaven and earth. There is only one of these two trees in each cave, and it takes 999 years to mature and be effective, and each time it is picked, another tree will grow again in other places.

These two materials are also not obtained by Danhuang Chi Zhonglin, such materials, I'm afraid that if it weren't for the prisoner's vein with magical exploration and prediction ability, even if it was the Dream Emperor, it would be difficult to find, right?

These materials are all rare in the world, or even unparalleled in the world, and people in the world will get a treasure if they get one of them, even if they don't use it, they can also exchange it with others to get enough magic weapons or elixirs to make people smile.

With the help of Qiu Changming, Lu Buqi was able to obtain these materials, which was simply atmospheric luck.

In addition to these main materials, there are also a lot of valuable auxiliary materials, this is how difficult it is to refine the real Divine Pill, even when Lie Yan knew that Lu Buqi was going to refine the Nine Turning Back Heavenly Pill, he was not optimistic at all, after all, even if it was Xuan Qian Dongtian, although the Nine Transformation Back Heavenly Pill was not the highest grade pill, it was definitely one of the most expensive pills.

After sorting out these pills very carefully, Lu Buqi reviewed the Dan Dao experience of Danhuang Chi Zhonglin again, and adjusted his mentality. After completely calming down and entering a state comparable to self-forgetfulness, Lu Buqi still did not start refining the Nine Turns Back to Heavenly Pill, but began to set up the formation.

Yes, Lie Burn warned Lu Buqi many times, the refining of the Nine Turns Back to the Heavenly Pill required a lot of energy, even with his current cultivation, if he didn't set up a gathering energy formation, he could continue to replenish Lu Buqi's lost Yuan Power, even if there was Lie Burn by his side to help, the lack of energy was enough to become the reason for failure.

For the formation, Lu Buqi didn't have much research, but Burning had a certain amount of research, and there was also a secret book of the formation in the legacy of Li Tian's blood spirit incarnation, so it was still very easy to use a spar or Xuanzhu to set up a gathering array.

The first step of the ninth turn back to Tiandan is to smelt the raw pulp of auxiliary materials, which is not difficult, that is, all the auxiliary materials are divided into four batches into the reaction furnace by distinguishing the different medicinal effects, and start refining.

This refining process didn't require Lu Buqi to spend too much energy, and Burning could use his spiritual sense to help him take care of it, and Xianyou Ding's independent behavior could be achieved.

What Lu Buqi has to do is to maintain a stable energy output as much as possible, and strive to use various methods to slow down the consumption of Yuan Force while outputting it.

Refining a furnace of divine pills is definitely no less difficult than fighting against a peerless powerhouse, it can be said that Lu Buqi is more focused at this moment than when he was fighting against Li Tian.
