The years flew by, and six months passed in a hurry.

Xiao Xuan has been in this cave for half a year.

At this time, Xiao Xuan was shirtless, and he was punching out a series of Dan seals on the Danding.

With the beating of the Dan seal, the Dan Ding has been constantly making a roaring sound, as if it is a moving rhythm.

At this time, Xiao Xuan had beads of sweat on his forehead, flowing down his cheeks.

Although it was already night, and the weather in the desert had turned cold, there was a relationship between Danding and Ding in this cave, just like the scorching summer sun shining.

It's even a bit breathless.

Suddenly, the flames in the pill tripod dissipated, the lid opened, and the three yellow pills were caught by Xiao Xuan from it.

"Haha, it turned out to be three reshaping pills, one of them is perfect, and two of them are successful. ”

Xiao Xuan finally laughed out loud.

I don't even wipe the beads of sweat that drip into my eyes.

When he was done, he took out a pill from the storage bag and threw it into his mouth.

And the pill that was thrown in was called the Substitute Food Pill.

The so-called substitute food pill is just a mid-grade Xuandan, and it is also refined after Xiao Xuan successfully refined the Qi Recovery Pill.

After all, he also has to eat, at this time, everything that can be eaten in Xiao Xuan's storage bag has bottomed out, and it is not like he is in the Bailing Mountain Range, where he can hunt some ordinary beast impact.

Although Xiao Xuan has reached the Dirty Xuan Realm and can resist some hunger, he must always eat, otherwise he will starve to death in a month. Choose to have the nourishment of Xuan Qi, and the energy of some foods is still needed.

It is said that only when you reach the Lingxuan Realm can you not eat to impact. This was also the reason why Xiao Xuan was anxious when he was trapped in that crypt in the first place.

But fortunately, when he came out of the Snow Ape Clan, he brought a lot of dried meat or something, otherwise he would have starved to death in the underground river.

When you reach the Xuan Realm, you can go without eating for half a year and be fine.

Today's Xiaoxuan can survive for a month, and if he is desperate, he can survive for a month and a half at most.

Of course, Xiao Xuan is not unprepared, if he doesn't have this substitute food pill, he can still impact even if he eats those herbs or something, after all, it is a Xuan demon itself, and it is not impossible to eat omnivorous. It's just that taking medicine is too wasteful.

Before, Xiao Xuan had found the pill recipe for the substitute food pill from the Xuan Lian Record, and the medicinal materials were quite sufficient, so he refined a few furnaces of the substitute pill.

A substitute pill can make Xiao Xuan survive for a month without feeling hungry.

In six months, Xiao Xuan only consumed six substitute pills.

For Xuan Xiu, it is too important to substitute the food pill during the retreat, otherwise you will have to eat something halfway, which will be too troublesome. Therefore, the price of substitute food pills in the market is also good.

After all, as long as it is a metaphysical cultivation under the spiritual realm, it is not necessary to eat, so the substitute food pill has become a necessary thing when going out to practice or retreat to cultivate.

Of course, some life and death points are not counted. Because with the entry of life and death, some skills of the whole body will fall into a state of sleep, and there is no need to use food to impact.

This is also the reason why some powerhouses in the Visceral Realm and the Dirty Realm have been in retreat for several years without eating.

"Master, you have now successfully mastered the refining of the Human-Rank Xuandan. Now it's time to start tasting the Xuandan at the bottom of the stairs and striving for the threshold of the real Xuandan Master. ”

Xiao Yao's voice sounded in Xiao Xuan's consciousness.

"yes. The human-level Xuandan is just a small path, and the ground level is the real threshold. ”

Xiao Xuan took a breath and said.

As long as the human-level Xuandan masters some medicinal properties and flames, these can be refined.

But the breakthrough of the ground level is not so simple.

It is not only necessary to have a full understanding of the medicinal properties of medicinal materials, but also to have higher and more detailed requirements for flames, timing, pills, etc.

Among them, flame and Danfang are the two main reasons.

The earth-level Xuandan is different from the human level, and it has higher requirements for flames, and if some medicinal materials do not have high-grade flames, they cannot be melted at all, or if there are flaws, the success rate of alchemy is not enough, and there may even be impurities.

And the other one is Danfang.

Every Danfang above the ground level is the treasure of every Xuandan master, even if it is a personal disciple, he is not willing to inherit it.

It is not difficult to buy a human-level Xuandan Dan on the market, as long as you have silver or Xuanshi, but it is not necessary to buy a Dan Fang above the ground level.

It is said that in the royal capital of the Dolan Kingdom, there was an auction of the mid-grade Xuandan Danfang in the ground level, and the Danfang was said to have sold for a sky-high price of 20 million lower-grade Xuanshi.

And if a Xuandan master wants to be promoted, if there is no Dan Fang, what else do you want to promote, for example, a Xuandan Master has mastered the upper grade of the human level, and the flame is enough, but there is no Ground Rank Dan Fang, then you will always be a Xuandan Master of the human level, and you cannot be promoted to the ground level.

In fact, every Xuandan master is respected, not only because of his alchemy ability, but also because of the Dan Fang behind him.

Of course, for alchemy, it is not only these, but also the teaching of a good teacher and personal effort and talent.

This will also account for a large factor.

Just like Xiao Xuan, he basically has all the favorable conditions, of course, the current Yin and Yang Flame can refine the lower grade Xuandan at most, but you must know that the Yin and Yang Flame can be upgraded, as long as you find a higher grade of fire, you can upgrade, but there is a restriction that he needs to find two flames before he can promote his Yin Yang Flame, if he finds a warm fire, to upgrade one, but not to upgrade the other, then the Yin and Yang Flame will be out of balance, but it will definitely explode at Xiao Xuan's dantian. Xiao Xuan, no matter how strong his body is, he will have no bones left. Moreover, the flame that Xiao Xuan found had to be of a higher grade than the current Yin and Yang Flame.

There is no clear division of the grade of the fire, but for the sake of convenience, the Xuanyue Continent is divided into four grades: the first grade, the second grade, the third grade, the fourth grade, and so on. However, everyone knows that there will still be strength and weakness in each grade, but there are too many fires in this Xuanyue Continent, and no one can count them, so they can only be divided into four grades, and as for the strength and weakness in the same level, it is up to the Xuandan Master to consider it himself.

And Xiao Xuan's yin and yang fire belongs to the first grade, it is said that it was the second grade of the fire before, but unfortunately, as he was trapped with the red bone demon chain for millions of years, the grade fell directly to the first grade.

The first-grade fire can refine the human-level Xuandan, the highest can refine the lower grade of the ground rank, and the second-grade fire can refine the Xuandan under the heavenly rank, and the third-grade can refine the heaven-level Xuandan, as for the fourth-grade Xiaoxuan, I don't know, this is the record in the Xuanlian record, but the Xuanlian record is not complete, according to Xiaoyao, it is not until the third layer of the red bone demon chain is opened.

However, Xiao Xuan also knew that he didn't have the ability to get involved in some real high-level cultivation things, so he still had to take every step in a down-to-earth manner.

Since the Yin and Yang Flame can refine the pill of the lower grade of the ground level, Xiao Xuan's first task is to reach the Xuan Dan Master of the lower grade of the ground level.

Soon Xiao Xuan entered a state of meditation.

After all, the consumption of alchemy on the mind is very serious, after refining several furnaces of Xuandan, Xiao Xuan's mind is consumed by most of it, and his entire body is already exhausted.

Fortunately, with the nourishment of soul power, Xiao Xuan recovered quickly.

Xiao Xuan didn't expect that the soul power would have this effect, maybe this was the interaction in the body. The power of the soul can attack the enemy's mind, but it can also nourish the mind.

Soon Xiao Xuan opened his eyes, and his state returned to its peak.

"Master, which level do you want to start refining first?"

Xiao Yao said loudly.

Xiao Xuan was silent for a moment and said, "It's still Diyang Dan, grasp some." ”

"Good"

Xiao Yao responded.

The so-called Diyang Dan, the lower grade of the ground level, can make the Xuan Xiu of the Bone Xuan Realm instantly recover fifty percent of the Xuan Qi in battle, and decrease in turn with the improvement of the grade, and the Xuan Xiu at the peak of the Bone Xuan Realm will recover two percent of the Xuan Qi at most.

But even so, he is also loved by many bone Xuan Realm cultivators.

After all, recovering the Xuan Qi during the battle can save your life, even if it's two percent.

In the Xuan Lian Record, there are more than a dozen kinds of pills that rank under the ground level, but the medicinal materials in Xiao Xuan's hand can only gather three kinds of pills, namely, Gushen Pill, Diyang Pill and Flame Poison Pill. Among them, the Gu Shen Pill can improve the strength of the mind, which is considered a rare elixir, and the Yan Poison Pill can be used in battle, which will release a flame-like poison.

And one of the advantages of the Flame Poison Pill is that even the Xuan Xiu of the Qi Xuan Realm can be used, although the technique is worse or something, but it is enough to deal with the Xuan Xiu in the early stage of the Bone Xuan Realm. It's just that its refining is a bit complicated.

Xiao Xuan compared these three Xuandan, and finally chose the Diyang Dan with relatively low difficulty.

And the other two kinds of Xuandan are more troublesome to refine, and Xiao Xuan has not yet refined the Xuandan at the lower level of the ground, so the first refining Xuandan is still simpler, and it is not too late to refine the other two after becoming proficient.

Soon Xiao Xuan divided four medicinal materials, each of which was composed of more than thirty kinds of medicinal materials, and each of them could refine a furnace of Diyang Pill, which meant that Xiao Xuan had four chances.

Soon the cyan flame in the Danding burned.

Xiao Xuan's palm skillfully grabbed a dark green plant from his side, this thing is called Tongtian Grass, a medicinal herb under the ground steps, which is a commonly used medicinal material in a healing elixir.

Its branches and leaves contain gentle energy, which protects the meridians of the user while the healing medicine is working.

Xiao Xuan looked at Tongtencao and catapulted into the Danding.

As soon as the Tongtian grass entered the danding, the gentle cyan flame wrapped around the Tongtian grass, and in an instant, the dark green leaves began to turn brown under the green fire, and gradually some sticky liquid appeared from it.

Immediately, Xiao Xuan used his strength to burst out again, and the rest of the branches turned into dust and discharged the Danding.

Immediately after that, Xiao Xuan controlled the flame again, allowing it to return to the level it had just now, and then took out a medicinal herb and threw it in.

When he arrived at the lower level of the ground, Xiao Xuan didn't dare to throw in one by one, but put them one by one, after all, the bearing capacity of each medicinal material above the ground level was different, and the degree of melting was different. With the current temperature and control of Xiao Xuan's Yin Yang Fire, it is difficult for Xiao Xuan to separate several waves to refine multiple medicinal materials at the same time, so it will take much longer in terms of time.

And just when Xiao Xuan had just put in the fourth medicinal material, there was a clear sound in the Danding, and the liquid that had been refined before instantly exploded and turned into nothingness.

The first time I refined the Diyang Pill, I failed!
