Liu Ming feels that the mana is flying fast, his face is full of awe.

At this moment, he had already waited for a long time, and he shot two black leather bags at the waist. Two black fogs came out and they were slightly condensed on both sides. They were turned into a silver mini bone. And the image of the flying skull.

"Master!" The voice of the girl and the boy came from the ear.

Liu Ming did not speak, just looked at them and simply gave a voice with God.

The next moment, the skeleton immediately waved a pair of tongs and hugged Liu Ming's thigh, while the flying skull and the second line of the yarn immediately wrapped around the arm.

Liu Ming nodded slightly, and carefully examined all the materials in the waist and the storage symbol. After closing all the eyes, they closed their eyes and began to control the speed of the mana flow in the body. After the mana is finished, enter the mysterious space.

As time passed slowly, his face gradually became pale from the previous run-up, and the black mist that had been continually surging was also becoming thinner.

When his mana was taken nine out of ten, the suction in Dantian suddenly came to an abrupt end.

When Liu Ming saw this, his heart was relieved with a slight sigh of relief. As a result, he had not waited for much of his thoughts. He only felt a sound of "嗡" in his ear, and then he was black.

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

This space has an acre size, which is much larger than the area when it was last accessed.

Liu Ming’s eyes swept away the flying skull and skeleton, and both of them were smoothly brought to the mysterious space.

"Well, now there is time, you two will practice well." Liu Ming waved his hand and whispered.

"Yes...master..."

The bones waved a pair of giant tongs, and quickly jumped down, and a flashing body appeared in front of a wall of more than ten feet, while the tail hook swinged. Crashed into the air wall.

The flying skull was not willing to show weakness, and nine false shadows were formed, and looming away from the other wall.

Seeing that the two spirits of the two spirits began to cultivate, Liu Ming’s eyes swept around and suddenly shouted:

"Luo Luo's predecessors, the younger generation have some things to ask for one or two, please also show up.

The sound echoed in the space. The result waited for about a quarter of an hour, but did not see the slightest reply.

He called for a few more times, but he still couldn't see his figure after waiting.

Liu Ming saw this and shook his head quite helplessly.

It seems that Luo Wei is not willing to appear at this time, or is in a deep sleep.

He immediately sat cross-legged. I began to recall some of the contents of a book that introduced the Zhongtian Continental drug system and types in the Wanshi Hall.

According to the records, Zhongtian mainland Xiu Xianjie's division of medicinal herbs is extremely detailed, and it has become a large system of cultivation and cultivation, which is not comparable to Yunchuan.

Although the average cultivator uses the applicable level of medicinal herbs, it is only distinguished by a simple spiritual level, a condensate level, a chemical level or even a true level. And according to the degree of difficulty in refining, it is called low-grade or high-grade medicinal herbs.

However, in fact, each level of medicinal herbs can be divided into inferior, ordinary and imported medicinal herbs.

Every kind of medicinal medicine is refining, and it is inevitable that it contains some impurities that are not beneficial to the user, and can be easily identified by various means.

Among them, the inferior medicinal herbs are more than 50% of the harmful impurities in the medicinal herbs. The medicinal preparations with a purity of less than half of the medicinal herbs are ordinary medicinal herbs with a purity of between 50% and 70%, and those with a purity of more than 70%. Among them, 70% to 80% can be called the medicinal medicinal herbs, 80% to 90%, then it can be called the medicinal medicinal herbs, the purity of more than 90%, is the rumored Tianpin medicinal.

Once the drug is in the product. The texture can be produced on the surface of the drug, and the more the texture, the higher the grade. These spiritual lines are also called Danshi. Therefore, even if it is not an alchemy teacher. It is also possible to simply distinguish the grade of the medicinal drug by the amount of dans.

In general, Dan Shangsheng has three of the following dans, which are ordinary products. Three or more of the following dans are the land products, and six or more of them are natural medicinal herbs.

Once the drug is ingested, the value and the price of the drug can not be compared with the ordinary drug. After all, the higher the purity of the drug, regardless of the effect and the resistance, is far from comparable.

Even some special medicinal drugs, which may be the difference of the purity or the semi-finished purity, may make the effect of the world different.

In the Zhongtian mainland, only the alchemy master who can refine the medicinal herbs can be called the true master of alchemy.

Liu Ming now recalls that the Qing Dan that was refining it in the South China Sea seemed to have two deniers on the surface, and it was also the name of the master of alchemy.

Of course, it is natural to refine the spirits of the spirits and the condensate crystallization of the medicinal herbs.

After all, the former is also reliable in the power of the Zongmen or the family, and is piled up with a large amount of material resources. The latter can only rely on its own alchemy talent.

Liu Ming thought about a turn, and vaguely remembered that when he entered the mysterious space in Yunchuan Xuanjing, he used a large number of refining the same spiritual-level medicinal herbs to refine a medicinal medicinal herb with a dan.

The same is true of the entire cultivation community. The more cultivaters who cultivate high realms, the harder it is to find an alchemy master who can refine his own medicinal herbs.

Liu Ming thought about this, suddenly thought of moving from the waist to the snail will be placed in the three-color flame wrapped in the silver medicinal jade box, open the lid, gently with a pair of fingers Look carefully in front of your eyes.

After passing through the three-color lamp flame, it was confirmed that the surface was indeed three golden dans. After Liu Ming’s eyes flashed a faint color, he shook his head again and collected the dan.

"Then start with Condensation Dan."

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

After half a day, after careful consideration, he immediately shook his sleeves and flew out a light silver small tripod. After a blur, he turned into a few feet high and landed firmly on the ground.

He touched his sleeve again and pulled out a pale yellow symbol.

The surface of the symbol is covered with dense silver crystals, which is a common storage symbol for the alchemy material.

When he was about to break the storage symbol, a piece of material needed for alchemy would be scattered after a flash of yellow light.

These materials were carefully distributed in the previous month, according to the proportion of materials required for condensation, enough for his day of alchemy.

Because it is in the mysterious space, the materials used in alchemy are not really consumed, so in theory he only needs to prepare an alchemy material to make an endless refining of the drug, but he has always prepared five copies. .

In Liu Ming’s eyes, the flash of light flashed, and the one-handed method changed.

The silver-colored spirit on the surface of the Ding furnace suddenly flashed, and with the rumbling sound, the Ding cover slowly opened.

His sleeves were raised, and a wind blew through it. The alchemy material of one place went to the inside of the furnace.

The sleeves were gently swayed, and the cover was slowly closed.

After doing all this, Liu Ming sat cross-legged, and there was a word in his mouth, and his hands were smashed, and the road was constantly pouring into the silver furnace.

After the diver's furnace trembled slightly, the red flame underneath ignited and wrapped the silver ding furnace.

The second day.

Suddenly there was a popping sound of "砰" in the silver ding furnace, followed by a scent of scent from the inside of Ding.

Liu Ming's brows were slightly wrinkled, and the hands of the cockroaches were collected. After taking out a black residue of material from Ding, he took out a light yellow symbol from the sleeves. Into, started the second alchemy.

......

One day after a month, when Liu Ming took out a black residue from the silver diners in front of him, his brow could not help but squat.

This is already the 30th refining of this condensed Dan, the first 30 times did not even have a success, even the lowest purity of the finest medicinal herbs did not become one.

I thought that I was a little careful in alchemy. He couldn't help but sigh. It seems that this condensate period is really a bit high compared to the difficulty of refining the medicinal herbs.

He got up and stretched his muscles and bones, and after a little observation of the cultivation of the skeleton and the flying skull, he sat down again and continued to refine Dan.

......

Another month passed, and Liu Ming was still sitting in front of the Dan furnace. The sensational sensation of the law controlled the fire, and the sweat on the head of the bean was thrown out.

Three months later, Liu Ming looked at a burning scent of Dan Wan, and he smiled bitterly.

Six months...

Time flies, and the time of the year passes by in a blink of an eye.

In the mysterious space, Liu Ming still sits in front of the silver Dan furnace, looking at a silver-colored Dan Wan in front of her eyes, and finally a hint of joy in her face.

This condensed Dan is the only successful one after Liu Ming has tried and tested hundreds of times in the past year. Thanks to his previous experience in alchemy.

After a little identification by a simple esoteric record recorded in the classics, the first condensed Dan is only 30% pure and can only be regarded as a poor remedy.

Although it is only a 30% pure medicinal herb, it greatly enhances Liu Ming’s confidence.

You know, ordinary people, let alone face hundreds of repeated failures, even in the face of dozens of dozens of times, dozens of failures, many people have long since lost confidence.

He was about to put this Dan into the jade box that had already been prepared, and then smashed a storage symbol, took out the material and put it into the silver dan furnace in front of him, and began to concentrate on continually refining Dan.

Now that he has had his first success, Liu Ming believes that the next time he refines his medicinal herbs, he will naturally not be separated for too long.
