In front of a steep mountain wall, only through the two-layer formation can you see a hidden cave, which is the cave where Xiao An killed the leopard.

Today's cave house is no longer desolate in the past, the entire cave house has a new look, and there are three more powerful big characters above the cave house: Du Zhixuan.

Zhizhi, which originally refers to sticking to his own ambition, contains the encouragement of the owner of this cave to himself.

Today's cave house is very different from what it used to be, with only one hall, and now the cave house has added a refining room, three storage rooms, and two bedrooms to it. A small part of the stone taken out of these rooms during the opening process was turned into tables and chairs, etc., and placed in the hall and bedroom. Xiao An even specially bought a set of tea sets and placed them on the stone table in the hall.

Although the newly opened refining room is much wider than the hall, it is now full.

In the center of the refining room was a short and fat three-legged refining furnace, although this refining furnace was only more than half a human tall, but its thickness was much greater than its height. On the body of the Ding furnace, there are three huge oval windows, which can easily observe and control the items in the furnace.

Next to the furnace stood a multi-tiered shelf, on which dozens of materials were neatly arranged. These ingredients vary in size, from the size of a soybean grain to the size of a watermelon.

On the other side is a flat iron platform, which is about one zhang long and half a zhang wide. Bursts of cold air emanated from the iron platform, which was actually made of cold iron. And under the iron platform, there are dense spiritual patterns, forming a mysterious formation.

If the formation on the iron platform is activated, an extremely low temperature area will be formed above the entire iron platform, which is specially used to "quench" the refining magic weapon.

On the iron platform was a disc-shaped, more than an inch high, the size of which was two circles smaller than the plate used for eating, which should have been a semi-finished product that had been refined in advance.

Xiao An was standing in front of the refining furnace at this time, and the red sun spiritual fire slowly flew out of the spirit cultivation array and floated down to the bottom of the refining furnace.

Under Xiao An's control, the spiritual fire that was only the size of a walnut in the main body kept changing, and the upper part of the spiritual fire was like a heavenly maiden scattering flowers, constantly scattering and expanding, and finally wrapping the bottom of the refining furnace completely.

After a while, the refining furnace was filled with a blue flame, which was a little different from the ordinary flame, this blue flame seemed to be a mist, and the tiny particles in the mist were a flame.

This kind of flame is transformed by the spiritual fire at the bottom under the action of the formation in the refining furnace, and the effect of adjusting the temperature in the furnace can be achieved by simply controlling the density of the blue flame.

Seeing that the flame in the furnace had stabilized, Xiao An took a piece of material the size of a peanut from the shelf on the side and put it into the refining furnace.

After this piece of material entered the refining furnace, it floated in the furnace and did not move, only to see the blue "mist" in the furnace quickly gather towards this material. Under the scorching blue flame, it was not long before the edges of the material showed signs of melting.

When he saw that the whole material had softened, Xiao An hurriedly pinched the trick with one hand. I saw that this piece of material was deflated little by little, as if an invisible hammer was constantly beating in the refining furnace, and after a while, this piece of material turned into a disc as thin as a cicada's wings.

Xiao An glanced at the materials, with a satisfied expression on his face, but did not take out the materials, but let them continue to accept the roasting of the spiritual fire. However, the blue "mist" around the material gradually thins out and gradually returns to the level before the material is put in.

Then Xiao An stretched out his hand and threw the disc-shaped semi-finished product on the iron platform into the refining furnace, and the disc-shaped semi-finished product occupied another position in the refining furnace, looking at the thin disc like a cicada's wings.

I saw that the blue flames around the disc-shaped object gradually became denser, while the concentration of flames near the thin discs like cicada's wings did not change at all. At this time, half of the furnace is dark blue, half is light blue, the contrast is stark, and it is very beautiful.

After a while, the disc-shaped object was burned red throughout, especially the material on the upper surface of the disc-shaped object, which had been burned as crystal clear as water.

Seeing that the heat was sufficient, Xiao An hurriedly controlled the thin slices like cicada wings to stick to the surface of the disc-shaped object. The size of the slice and the size of the disc are exactly the same, and the two fit together tightly, no more, no less.

Then part of the blue flame in the furnace suddenly began to shrink, and finally gathered into the shape of a carving knife, and the blade part had turned dark blue, and the farther away from the blade the blue became lighter.

After the "carving knife" was formed, it was carved along the laminated disc, and the "carving knife" ran extremely fast, only to see some material debris sprinkled down like a drizzle.

In a short time, most of the thin layer of material was removed, and the remaining part had been carved into countless intricate spirit patterns, many of which were as thin as silk.

And the materials that were removed were not discarded, but gathered in a corner of the furnace, and melted into a piece the size of a soybean by the blue flame, and were put back into the pile of materials by Xiao An.

Then the third piece of material was also put into the refining furnace by Xiao An, and this piece of material was finally stretched into a thin plate with the thickness of a grain of rice, and then the front and back sides of this material were carved with complex spiritual patterns, which were not all carved on the surface of the thin plate, but a considerable part of the spiritual patterns ran through the thin plate.

Finally, the sheet flew towards the semi-finished product that had been refined in the furnace, and after careful alignment, the sheet was also attached to the previously refined item. Tens of thousands of silk-thin spiritual patterns and cicada-thin spiritual patterns on the thin plate were connected together in the slightest, and dissolved into one under the blue flame.

At this time, a large jade basin about three feet square under the shelf was moved by Xiao An to the cold iron platform with his mana, and the jade basin contained several dark brown stone-like items.

After Xiao An activated the formation on the iron platform, the space half a foot high above the iron platform suddenly turned into a world of ice and snow, and even the air became foggy, as if it had been frozen. However, the stone-like items in the jade basin slowly melted away, and finally turned into a turquoise liquid.

When all the stone-like items in the jade basin turned into a turquoise liquid, the magic weapons in the refining furnace were thrown into the turquoise liquid in the jade basin like lightning, accompanied by a sharp "hiss, hiss", and countless green mist rose from the jade basin. But after exceeding the height of three feet of the cold iron platform, it turned into gray particles and fell into the jade basin again.

When he saw that the "Spirit Gathering Array Disk" he had refined was successfully baked, Xiao An was tired and collapsed on the ground, the consumption of the refining weapon to the Yuan Shen was too great, and at this time, Xiao An really wanted to lie on the ground and sleep for a few days immediately.

After Xiao An lay on the ground and gasped for breath, he struggled to sit up and began to cultivate the "Strong God Technique", which is a special technique recorded in the refining materials to restore the Yuan Shen. This exercise can only be effective if practiced when the Yuan Shen is tired. And every time he cultivated, the Yuan Shen would become more condensed than before.

After a long time, Xiao An finally ended his meditation, and Xiao An was in good spirits at this time, and he still looked tired just now.

After getting up, Xiao An picked up the iron platform and observed carefully, this was the first spirit gathering array disk that he had refined after going through a lot of hardships.

This Spirit Gathering Array Disc looked extremely good in all aspects from the outside, and it didn't look like it was refined by a novice at all. Xiao An casually took out three spirit stones to test the effect of this magic weapon, and Xiao An grinned happily and began to giggle.

After confirming the effect of the Spirit Gathering Array Disk, Xiao An did not rest but continued to refine the weapon.

It has been three months since I got the refining furnace and spiritual fire, and I have been busy in the past three months, that is, I have to practice the "fire control technique" to get familiar with the refining furnace and spiritual fire, and I have to collect and process materials in advance according to the items to be refined.

Especially when he first got the spiritual fire, Xiao An was not familiar with the power of the spiritual fire, and he practiced the "fire control technique" in the residence of the outer disciples in the sect all day long.

As a result, more than 30 things were burned in more than ten days, especially Xiao An's head, hair and eyebrows were roasted, and turned into a "bare egg". In the end, he almost set the house on fire, so scared that Xiao An no longer dared to practice in the house.

In desperation, Xiao An could only find other places as a base for his great refining business. After thinking about it, it is okay to go to the cave near Qishifang City, but this place is too remote, and how to ensure safety is the first problem.

Coincidentally, when Xiao An got the Ding Furnace and the Spiritual Fire, he searched out a set of "Wind and Fire Two Ritual Arrays" arrays that could be attacked and defended from the monks who chased and killed Zhou Huzi. Combined with the set of array plates that Lingyue left for herself, the array that concealed and imprisoned the aura actually protected this cave from wind and rain.
