In front of me is a stone house made of huge dark gray stones, about a dozen zhang in size.

A half-zhang pure black round stone platform is placed in the middle of the stone house, and there is a circular hole about the size of a foot in the middle of the black stone platform, and several rows of small holes of different sizes are drilled in the side wall of the hole.

At this time, a quaint refining furnace was placed on the stone platform, and it was emitting bursts of heat under the blazing fire. Around the furnace are more than a dozen shelves, piled high with a variety of different materials.

The two figures were constantly busy beside the refining furnace, putting pieces of materials into the refining furnace for refining, and constantly adjusting the processing techniques of the materials and the timing of adding them.

Under the reflection of the earth fire, I could see these two figures clearly, one was a middle-aged monk, and the other monk was an old man with gray hair and a lot of wrinkles on his face.

With a "hiss, hiss" sound, the middle-aged monk quenched the refined materials. Then he took the quenched material in his hand and examined it carefully, and the old man also came over with a nervous expression.

After carefully examining several pieces of materials, the middle-aged monk took out one of them separately and placed it with a fragment of a ritual artifact, and made a detailed comparison between the two.

After a while, the middle-aged monk handed the two pieces of material together to the old man next to him, "Elder Lu, you see, it's successful, we have finally refined this material!"

"Cough, cough" As soon as the middle-aged monk finished speaking, he couldn't help but let out a violent cough.

"Master Xu, are you okay?We haven't been out of this refining room for three months, why don't you rest for a while?" The old man next to him hurriedly supported the middle-aged monk who was coughing.

This middle-aged monk was the head of the Xu family who suddenly disappeared more than three years ago, but at this time, the face of the head of the Xu family became a little pale.

"Elder Lu, in order to be able to crack these fragments, it has taken us three years, but every time it's me, a junior, who can't resist it first, how can I be embarrassed. The head of the Xu family finally stopped coughing and said a little tiredly.

The "Elder Lu" in the mouth of the head of the Xu family was the person who pretended to be a servant and led the three heads of the family, Xu, Lin, and Han, into the desolate courtyard outside Qishifang City, but the real identity of this person was one of the refiners of the Wuji Sect with a very high level of refining.

"Master Xu, don't worry, anyway, we're a little bit of an eyebrow, you can spare some time and practice the Golden Light Transformation Essence Technique first.

This technique was specially selected for you by Master Wei, and with the heavenly treasures collected by Master Wei for you, it won't take you a few years to reach the ninth level of qi refining. ”

After this Elder Lu had placed the Xu family master in place, he took out a few pieces of paper and began to record the detailed process of refining the materials just now. Elder Lu was a ninth-level Qi refining cultivator, and his physical strength was naturally much better than that of the Xu family master at the seventh level of Qi refining.

After Elder Lu recorded it, the head of the Xu family was almost rested.

The head of the Xu family walked to a table in the corner of the stone house, on which dozens of pieces of fine rice paper were placed clutteredly, and the paper was already full of complicated spiritual patterns.

The head of the Xu family picked out one of them, and after careful deliberation for a long time, he took the brush and revised it. Then the head of the Xu family walked to the refining furnace and began to copy the formation on the paper.

Just when a formation was about to be completed, the aura contained in a spirit pattern that had just been carved suddenly became chaotic, and this confusion instantly extended to all spirit patterns, and then this piece of material emitted a dazzling light.

A muffled sound sounded in the refining furnace, and the entire piece of material had turned into countless brilliant sparks erupting from the refining furnace. The head of the Xu family bore the brunt of the blow, and was hit in the chest by the spark mixed with the ground fire and the molten material.

Elder Lu on the side hurriedly turned off the ground fire, and helped the head of the Xu family to the side and lay down. Just now, during the refining process, a fryer appeared, but fortunately, the degree was lighter. It shouldn't cause much harm to the Xu family master, Elder Lu thought secretly in his heart.

But when he saw the situation of the Xu family master clearly, he startled Elder Lu. At this time, half of the Xu family master's face was red and hot, but the other side became iron blue, and a layer of frost and snow quickly condensed. Even the hands of the head of the Xu family had the same abnormality, one hand became hot and the other hand became cold.

"Fire poison?" Elder Lu shouted with some surprise.

The head of the Xu family nodded effortlessly, and gestured to his arms with his eyes. Elder Lu comprehended the meaning of the Xu family master, and reached out to take out a jade bottle from the Xu family master's arms.

After taking the pill, the abnormality of the Xu family master gradually disappeared, and the recovered Xu family master hurriedly got up to thank Elder Lu for his help.

"Family Master Xu, why are you doing this, with our friendship, you should rest first!" Elder Lu hurriedly got up and pressed the Xu family master back into the chair.

"Master Xu, how long have you been this fire poison, do you need me to ask the alchemist of the sect to come and check it for you?"

The Xu family master knew his own situation, and after listening to Elder Lu's suggestion, he shook his head with a wry smile, "I have been using this fire poison for more than ten years, and there is no cure for it, so I can only rely on pills to suppress it."

Fire poison is different from other poisons, and when it first enters the body, it can be cured with ordinary elixirs that dissolve fire poison.

However, if the treatment time is delayed, it will be difficult to remove the fire poison that has invaded the body, and the symptomatic elixir can only be equipped according to the patient's own condition. Even so, it can only suppress the fire poison and make it no longer attack in the body for a short time.

However, this method treats the symptoms rather than the root cause, and every few years the original elixir must be adjusted accordingly according to the monk's physical condition. Therefore, in the case of the Xu family master, it is best to find a previous alchemist to refine the pill for him.

The qualifications of the Xu family master when he was young were not good, and in order to get ahead, he could only improve from the aspect of refining weapons, so this person often refined some difficult magic weapons in the family's earth fire house.

Later, during a refining process, a very slight fryer appeared, and at that time, the "future" Xu family master did not notice that there was also a problem with the stone platform prohibition that suppressed and purified the earth fire, and a small amount of earth fire had leaked out.

By the time the fire poison broke out, the best treatment time had passed, so he could only ask the Han family monk to prepare the right pill according to the Xu family master's physical condition.

The Earth Fire House in Qishifang City just added a ban above the Earth Fire. This prohibition is not only to suppress the earth's fire, but also to filter the fire poison. Whether it is in terms of structure or safety, it is much worse than the earth fire house at the Cangyue faction.

After Elder Lu helped the head of the Xu family into his bedroom, he returned to his residence.

Sitting at his desk, Elder Lu had to sigh that the head of the Xu family was really talented in refining weapons, and under his leadership, he finally succeeded in concocting the refining technique of the Yuan Ying magic weapon materials today.

You must know that the sect has not pressed the matter of cracking the fragments on its own, and the several refiners in the foundation building period in the sect have never stopped studying this, but there has not been much progress so far.

And the Xu family master studied this fragment two years later than those foundation building monks in the sect, but it could be cracked immediately. Thinking of this, Elder Lu felt a burst of excitement in his heart, and when the time came, he must exchange for enough materials to support himself into the foundation building period.

Mastering the refining technique of this high-level material can improve the quality of the natal magic weapon of the Jindan stage monks, which is of great help to improve the strength of the Jindan stage monks. The reason why the Xuanjian Sect was able to be the leader of several local sects was not only the benefits of the exercises in their sect, but also the fact that the Chu sect master of their sect had a good natal weapon in his hand.

Just as Elder Lu confirmed that the content of the record was correct, a flash of light suddenly flashed in the corner of the room, and a transmission note quietly appeared in this corner.

After listening to the content of the transmission note, Elder Lu hurriedly changed into a low-level steward's costume and limited his cultivation to the fifth layer of qi refining before he walked out of the house, and then there was a sound transmission platform hidden in the corner.

The matter of the Xu family master's participation in the fragment cracking was highly secret in the sect, and even the Xu family monks did not know about it, and he was disguised as a low-level steward who was responsible for cleaning the Xu family master's courtyard.

As he walked to the desk, Elder Lu glanced at the paper on which the contents of the record were recorded, hesitated for a moment, and then reached out to grab it. When his fingers touched the paper, a soft aura poured out from a staff ring on Elder Lu's hand, wrapping the paper in the aura.

When the aura vanished, the paper on the table disappeared, and the ring returned to normal. This ring looks like it's just made of ordinary stone, and no one would have thought it would be a rare storage ring.

Storage rings are magic weapons made of empty stone as the main material, and it is said that storage rings and storage bracelets made from empty stone millions of years ago are extremely common. This kind of ritual vessel is not only beautiful in shape, but also has a storage space of several zhang and dozens of zhang in size, and is far more convenient to carry than the current storage bag.

It's just that later, there was a great change in heaven and earth, and the veins of the Void Immortal Stone suddenly became very few. The shortage of storage tools was extremely scarce for a while, which brought great trouble to the monks at that time, and later the monks created storage tools that did not need empty spirit stones, which are now widely used by monks.

The head of the Xu family stood quietly in front of the window, and only breathed a sigh of relief when he saw Elder Lu leave. A young monk was immediately called, and after a few whispered words of advice, the young monk hurried away.

The head of the Xu family lay back on the bed, looked at the jade bottle in his hand and began to be in a daze. At this time, the cork of the jade bottle has been removed, and the jade bottle is empty.
