In the casting room, Dan Xuan pricked up his ears and listened, Lin Qing spoke in detail next to him, from Lin Qing's explanation, Dan Xuan also had some understanding of the general steps of the refining tool, and this time he really knew that the refining tool was indeed very cumbersome......

Lin Qing finished talking about the basic knowledge of refining weapons, and he planned to start demonstrating the refining method of Xuan Weapons, but then he seemed to think of something again, and added to Dan Xuan: "There is another very important thing for us instrument masters, that is, 'instrument formula'. The so-called 'instrument formula', in fact, is the recipe for refining the mysteries, these instruments are countless predecessors after a long time and gradually summed up the effective refining method, we refining the mysteries are in strict accordance with the requirements of the 'instrument recipe' refining, otherwise, a slight difference in the pool, it will cause the material to be destroyed, the previous efforts are wasted......"

These Dan Xuan already knew in his previous life, and when it came to the instrument formula, Dan Xuan suddenly thought of one thing, there seemed to be a lot of instrument prescription in the ancient ring on the fingers of his right hand, and the pile of scroll-like things was the so-called instrument prescription.

There are many differences between refining tools and refining medicine, but they also have a lot of similarities, and the same fire control techniques are counted as one, and they all need to be refined in strict accordance with the refining method, but they can also be barely counted as one. Even, some people of the older generation often say that the requirements for refining weapons for the refining method of the master are more stringent than those for refining medicine, and whether it is true or false, Dan Xuan does not know.

Lin Qing looked at Dan Xuan and didn't show any embarrassed expression, knowing that his apprentice should be able to accept some basic knowledge, so he preached again: "The prescription is not a simple piece of paper, but the same as the medicine prescription of the pharmacist, it is a scroll containing spiritual power, which is carved out by some high-level instruments with soul perception bit by bit, each instrument prescription is extremely precious, and even some high-level prescriptions are things that can be encountered but not sought. And most of the instrument recipes are in the hands of some instrument master families, just like the instrument clan of my Ork Empire, they have many high-level instrument recipes, and they never pass them on......"

"Alas......" As soon as the words fell, Lin Qing let out a long sigh, his gray eyebrows wrinkled weakly, and the helplessness lay on Lin Qing's old face.

Noticing that his master was very helpless when he mentioned the instrument clan, Dan Xuan secretly speculated in his heart: "My master may have a slightly complicated story with this instrument clan......

After a short silence, Lin Qing took a deep breath, looked at Dan Xuan, and returned to a pair of old eyes calmly and confidently. After adjusting his state, Lin Qing said to Dan Xuan: "Xuan'er, now I will demonstrate the refining method of the first-order mystic weapon-fish intestine sword, you have to watch it carefully, you must carefully experience the steps and rhythm of the refining weapon, and gradually try to refine it yourself in the future......

As soon as the words fell, Lin Qing's shadow flashed, and his dry right hand appeared on the porcelain stove on the Xuanhuo platform, and at the same time, Lin Qing's hoarse voice sounded again: "Our appraiser's fire control tools are not the same as those of the pharmacist, our appraiser uses a porcelain furnace made of black jade, red flame stone and other materials, the porcelain furnace is good and bad, you will slowly know the specifics later......

A thin wisp of crimson Xuan Qi flowed out of Lin Qing's right hand through the Xuan Huo meridians, and in an instant, a crimson flame appeared on the back of Lin Qing's hand, and at the same time, the temperature in the casting room seemed to suddenly increase a lot.

Lin Qing slowly withdrew his right hand, a crimson flame was still churning in the porcelain furnace, clusters of flames tumbling upwards violently, and then gradually disappeared into the void.

Lin Qing's cloudy eyes stared at the crimson flames that were beating in the porcelain furnace, and on his old face, there was a deep color of nostalgia, Lin Qing was a little like seeing his life beating in front of him at this time, there was a strong helplessness, but more was a deep attachment.

After a while, Lin Qing's dry fingers swept in front of him, and after the ring on Lin Qing's finger flashed, a few things like metals and herbs suddenly appeared on the Xuanhuo platform, and Dan Xuan knew that these should be the materials needed to refine the fish intestine sword. And the three things that are like grass should be the so-called utensils.

In fact, when the master uses Xuanhuo to purify and smelt, it is nothing more than to make many metal materials can be bonded together to exert their power without distinguishing between you and me, but most of the metal materials are difficult to integrate with each other.

Therefore, when refining the instrument, the master gradually had the raw material of the instrument. Of course, the grass does not have only one function, some of the grass can increase the fusion of metals, and some of the grass can also greatly improve the toughness or rigidity of the mystery, in short, the refining tool has developed to the present, the role of the grass has become ever-changing, elusive, and closely linked with the mystery, difficult to solve.

In addition to the three kinds of herbs, there were also three metal materials the size of a baby's fist on the Xuanhuo platform, and his dark eyes swept over the three materials in turn, and Dan Xuan found that he knew two of them. The black, glowing metal should be the "Nether Iron", and the fiery red but restrained metal should be the most common "Fire Copper" in the refiner.

"Netherworld Iron, Fire Copper, Soul Stone, Golden Thread, Comfrey, Flame Grass......" Lin Qing seemed to see that Dan Xuan's eyes were a little confused, so he introduced Dan Xuan in turn.

Lin Qing took a deep breath, and then exhaled slowly, his dry and rickety body gradually straightened up between exhalation and inhalation, and the light in his small eyes also appeared, and then he said as if he was making some kind of judgment: "I'm going to start ......"

In an instant, Lin Qing's phantom moved, and a flame grass was thrown into the porcelain furnace, and the crimson flame quickly wrapped around it, the flames churned violently, but the grass was gone.

After a few moments, the fierce crimson flames gradually weakened and smallened, and a pink liquid gradually emerged from the flames, gradually spinning on the beating flames.

At the same time, Lin Qing's soul power attached to the flames suddenly increased, and under the control of Lin Qing's huge soul power, the flames tumbling in the porcelain furnace were as if they had received an order, and they were extremely docile.

Dan Xuan's soul was very powerful, so powerful that almost except for the Venerable Cultivators, the Xuan Qi who cultivated above couldn't detect any situation of Dan Xuan, including the Xuan Qi level. Moreover, Dan Xuan would not be discovered when he investigated the cultivators below the Venerable.

Under Dan Xuan's soul perception, the soul power of his master Lin Qing is very strong, and even compared to his grandfather Danqing, it is only slightly inferior. Lin Qing's soul was so powerful, and Dan Xuan knew from the first time he saw Lin Qing that this withered and rickety old man was an out-and-out spirit king. Such a profound cultivator, who is also a master of the craft, is willing to succumb to an inconspicuous blacksmith shop in the family...... My master should be a person with a story......

Dan Xuan thought so in his heart, but his eyes kept staring at Lin Qing's refining process, at this time, the pink medicinal liquid was still rotating above the Xuanhuo, and the crimson flame below was also beating, as time passed, some brown or black impurities continued to precipitate from the surface of the pink medicinal liquid, which gradually turned into a gaseous state and evaporated into the air under the scorching of the Xuanhuo, and then disappeared......

The impurities continued to precipitate and evaporate, and the pink liquid at this time was also gradually shrinking, and finally gradually shrinking when it was slightly larger than the thumb, the ring on the finger of Lin Qing's right hand flashed, and more than a dozen black jade bottles appeared neatly on the Xuanhuo platform. At this time, the volume of liquid was much larger than the volume of liquid refined by Dan Xuan when refining the pill.

Lin Qing did not hesitate, his hands knotted his handprints, the soul power surged, the black jade bottle on the Xuanhuo Platform slowly suspended, and then gradually tilted, Lin Qing's huge soul power controlled the pink liquid to rotate slowly, as the rotation progressed, the pink liquid gradually turned into a wisp of silk in the air and crossed an arc into the black jade bottle, just a moment, a whole ball of pink liquid was neatly packed in the black jade bottle, placed on the other side of the Xuanhuo platform.

After doing this, Lin Qing's complexion did not change, his hands did not stop at all, and a fiery red phantom was immediately thrown into the porcelain furnace, but Lin Qing was about to refine the fire copper at this time.

The same crimson Xuanhuo wrapped the fist-sized fire copper, and then the flame gradually softened, and a fiery red liquid gradually surfaced, and the same Xuanhuo gradually refined, and the fiery red liquid gradually shrank in the continuous rotation.

When the fiery red liquid gradually shrank to more than an inch in diameter, it was also transferred by Lin Qing into the black jade bottle and put aside......

......

Comfrey, golden thread, soul stone, nether iron, when Lin Qing finished refining all the materials, it was already more than two hours later.

Lin Qing exhaled slowly, and there was a hint of relief in his eyes, but Lin Qing's spirit was still vibrant, and he didn't show any tiredness. Obviously, the refining of this first-order mystical weapon was still very easy for Lin Qing.

Lin Qing looked at the churning flames in the porcelain furnace, and then beckoned, and a piece of wrought iron flew over the shelf next to him......

"Now is the process of smelting...... Lin Qing's hoarse voice sounded again.
