Liu Ming felt the mana in his body pass quickly, and his face was full of solemnity.

At this moment, he had been waiting for a long time, and with a tap of the two black leather bags on his waist, two black mist rolled out, and condensed slightly on both sides of it, turning into a silver mini bone scorpion and a hideous flying skull.

"Master!" came the voices of the girl and the boy.

Liu Ming didn't speak, just glanced at them, and simply commanded with his divine sense.

The next moment, the bone scorpion immediately waved its pincers to hug Liu Ming's thighs, and the flying skull let go of the hair filaments and tightly wrapped around his arm without saying a word.

Liu Ming nodded slightly, and after carefully checking that all the materials in the Sumeru snail and the storage talisman on his waist had been prepared, he closed his eyes, pinched his hands, and began to control the speed of mana flow in his body, waiting for the mana to be absorbed and enter the mysterious space.

As time passed, his face turned pale, and the black mist on his body became thinner.

When its mana was absorbed eight or nine times out of ten, the suction in the dantian suddenly stopped.

Seeing this, Liu Ming breathed a sigh of relief in his heart, but before he could think about anything, he only felt a "hum" sound in his ears, and then it was dark in front of him.

When he saw ahead again, he was already in a gray space.

This space is already the size of acres, and it looks much larger than the last time I entered.

Liu Ming's gaze swept over the flying skull and bone scorpion around him, and both of them were also smoothly taken to the mysterious space.

"Well, now there's time. You two should practice well. Liu Ming waved his hand and said in a low voice.

"It's... The hosts..."

The bone scorpion waved a pair of giant pincers. Quickly leap down and dodge. appeared in front of a gas wall more than ten zhang away, and at the same time, the tail hook swung and went wildly towards the air wall.

Not to be outdone, the flying skull instantly turned into nine phantoms, looming in the direction of another qi wall.

Seeing that his two spirit pets had begun to cultivate, Liu Ming glanced around, and suddenly, called out loudly:

"Rahu seniors, juniors have some things to ask for a word or two, and please show up.

Sound reverberates through the space. As a result, I waited for about a quarter of an hour, but there was no reply.

He called out a few more times, but after some waiting, he was still nowhere to be seen.

Seeing this, Liu Ming shook his head helplessly.

It seems that Rahu is reluctant to appear at this time, or fall into a deep sleep again.

He immediately sat cross-legged and began to silently recall the contents of some of the classics that he had read in the Hall of Ten Thousand Things that introduced the Zhongtian Continent's pill system and types.

According to the records, the division of the elixir in the Immortal Cultivation Realm of the Zhongtian Continent was extremely meticulous, and it had already become a major system in the cultivation realm of its own. It is not at all comparable to the Yunchuan Continent.

Although ordinary cultivators use the applicable level of the elixir, they are only distinguished by a simple spirit disciple level, condensation level, crystallization level, or even true pill level or above. And then according to the difficulty of refining, it is called a low-level or high-level elixir.

But in fact, each level of the pill is different in terms of the pure process of the pill. It can also be divided into inferior, ordinary and high-quality pills.

Each elixir is refined. It inevitably contains some impurities that are not beneficial to the user, and can be identified by various means.

Among them is inferior elixir. It is a pill with more than 50% harmful impurities in the pill and less than half of the purity, an ordinary pill is a pill with a purity of between 50% and 70%, and a pill with a purity of more than 70%. Among them, seventy to eighty percent can be called mortal pills, eighty to ninety percent can be called earth pills, and more than ninety percent of the purity is the rumored heavenly pills.

Once the elixir is in the product, it can give birth to spirit patterns on the surface of the elixir, and the more spirit patterns, the higher the grade. And these spirit patterns are also called Dan patterns. Therefore, even if you are not an alchemist, you can simply distinguish the grade of the incoming pill by the number of guò dan patterns.

Generally speaking, if there are three or less Dan lines on the Dan, it is a mortal product, three or more than six Dan lines are earth products, and more than six are naturally heavenly pills.

And once the pill is incorporated, no matter the value and the price itself, it cannot be compared with ordinary pills at all. After all, the higher the purity of the elixir, no matter the effect and the resistance it brings, it is far from being comparable to the latter.

Even some pills with special effects may be a difference in purity, or even half of the difference, which may make a world of difference in the effect of taking it.

In the Zhongtian Continent, only an alchemist who can refine the pill can be called a true alchemy master.

Liu Ming now thinks back to the fact that the Qingsan Pill that Fang Yao refined for him when he was in the South China Sea seemed to have two Dan patterns on the surface, and he really deserved the title of Alchemy Master.

Of course, the Entering Pill Master who can refine the Spirit Disciple level pill and the condensation liquefaction crystallization stage pill is naturally very different.

After all, the former is still reliable with the power of the sect or family, and it is piled up with a large amount of material resources, while the latter can only rely on his own alchemy talent.

Liu Ming's mind turned, and he vaguely remembered that when he entered the mysterious space in Yunchuan Xuanjing, he had used to refine a large number of the same spirit disciple-level pill to refine a mortal pill with a Dan pattern.

And the same is true of the entire cultivation world. The more a cultivator with a high cultivation realm, the more difficult it is to find an alchemy master who can refine an elixir suitable for his level.

Liu Ming thought about it so far, and suddenly took out the jade box containing the silver elixir wrapped in the three-color flame from the Sumeru snail on his waist, opened the lid of the box, gently pinched it with two fingers, and put it in front of his eyes to look at it carefully.

When through the three-color flame of the lamp, it was confirmed that its surface was indeed three golden pill lines, and after Liu Ming's eyes flashed a hint of deep groan, he shook his head again and put this pill away.

"Then let's start with the Condensation Pill first. ”

After muttering to himself, he immediately took out a Dan Fang from his sleeve and studied it carefully.

Half a day later, after some careful consideration, he immediately shook his sleeves, and a pale silver tripod flew out of it, and after a blur, it turned into a few feet high and fell steadily to the ground.

He reached into his sleeve again and pulled out a pale yellow talisman.

The surface of the talisman was covered with dense silver spirit patterns, which was an ordinary storage talisman used to hold alchemy materials.

He immediately crushed the storage talisman, and after a flash of yellow light, a pile of materials needed for alchemy was scattered all over the ground.

These materials had been carefully allocated by him in the previous month according to the proportion of materials needed for the Condensation Pill, which was enough for him to refine the Pill for one day.

Since it was in a mysterious space, the materials used in alchemy would not be really consumed, so theoretically, he only needed to prepare one alchemy material to refine the pill endlessly, but he had always been cautious and still prepared five copies.

Liu Ming's eyes flashed, and he changed his single hand, and punched a magic decision towards the silver Ding furnace.

The silver spirit pattern on the surface of the Ding furnace suddenly flashed, and with a rumbling sound, the Ding lid slowly opened.

As soon as his sleeve robe was raised, a gust of wind blew, and the alchemy materials in the place rolled towards the Ding Furnace.

The sleeve robe was gently stroked, and the lid was slowly closed again.

After doing this, Liu Ming sat cross-legged, chanting words in his mouth, his hands pinched and flicked, and one after another the Dharma Decisions continued to pour into the silver Ding Furnace.

After the Ding Furnace trembled slightly, the red flame below ignited, enveloping the silver Ding Furnace.

Day 2.

There was a sudden "bang" popping sound in the silver tripod furnace, and then a burnt smell wafted out of the tripod.

Liu Ming frowned slightly, and as soon as he collected the magic trick in his hand, he took out a cloud of black material residue from the ding, and then took out a pale yellow talisman from his sleeve, and after pinching and crushing, he poured the material into the ding, and started the second alchemy.

......

One day a month later, when Liu Ming once again took out a lump of black residue from the silver ding furnace in front of him, his brows couldn't help frowning.

This was already the thirtieth time he had refined this condensation pill, and none of the first thirty times had succeeded, and he hadn't even refined the lowest and lowest purity pill.

Thinking that he was also a little careful in terms of alchemy, he couldn't help but sigh lightly, it seems that this condensation stage pill is really a few grades higher than the difficulty of refining the spirit stage pill.

He got up and stretched his muscles and bones, and after observing the cultivation of the bone scorpion and the flying skull for a while, he sat cross-legged on the ground again and continued to refine the pill.

......

Another month passed, and Liu Ming was still sitting in front of the Dan furnace, urging the law to control the fire with a focused expression, and beads of sweat the size of beans appeared on his head.

Three months later, Liu Ming looked at a furnace of pills that emitted a burnt smell and smiled bitterly in his heart.

Six months......

Time flies, and a year has passed in a blink of an eye.

In the mysterious space, Liu Ming was still sitting in front of the silver pill furnace, looking at a silver pill in front of him, and a look of joy finally appeared on his face.

This condensation pill was the only one that Liu Ming had succeeded after hundreds of repeated trials in the past year, thanks to the fact that he had some experience in alchemy before.

After a little identification of a simple secret technique recorded in the Tongguò classics, the purity of this first condensation pill was only 30%, which could only be regarded as an inferior pill that could be regarded as a Chengdan.

Although it was only a three-percent pure elixir, it greatly enhanced Liu Ming's confidence.

You must know that ordinary people, not to mention facing hundreds of repeated failures, even in the face of dozens of times, dozens of failures, many people have already given up with confidence collapsed.

He immediately put this pill into the jade box that had been prepared on the side, then crushed a storage talisman, took out the materials and put it into the silver pill furnace in front of him, and began to concentrate on continuing to refine the pill.

Now that he has had his first success, Liu Ming believes that the next time he refines the elixir, he will naturally not wait too long. (To be continued......)
