After the top lid of the Dan furnace was opened, Ren Feiyan patted the storage belt again, only to see that various elixirs, spirit herbs and other medicinal materials flew into the Dan furnace one by one. There are only three or four ingredients in total, all of which emit different herbal smells.

Because the elixir refined by Ren Feiyan was the most ordinary Qi Rejuvenation Pill, there were not too many types of spirit herbs and elixirs needed. Only a few ordinary materials are needed. Among these four materials, there are Tianlian grass, Xingqi grass, Cangya Valley, and Sanwei Orchid.

Most of these materials are ordinary alchemy materials of the first or second order, and they are produced in large quantities in the immortal cultivation world, and they are not worth many spirit stones.

After these three or four kinds of materials for refining the Qi Returning Pill were packed into four different grids, Ren Feiyan immediately stretched out his hand and waved, and the lid of the Dan Furnace fell in response to the sound and closed tightly.

Closing the top lid of the Dan furnace, Ren Feiyan was not in a hurry to bring the earth fire up immediately. Instead, he calmed down the spiritual power of the magic decision just now, and kept his state of mind in a calm and stable state. She didn't want to fail again this time.

Therefore, she is not in a hurry, and tries to make herself smooth and natural in one go. Besides, now Ren Feiyan is not alchemy alone, he already has two helpers. Although she didn't know if these two novices could help, she still didn't want to lose face again in front of Li Zhaoyuan.

After Ren Feiyan was ready, his hands flew out four seals in succession, and shot into the four gilded carved dragons coiled outside the Dan furnace one by one.

Those four divine dragons were originally carved lifelike, and when Ren Feiyan injected the law decision, they suddenly seemed to come to life. They opened their dragon mouths, their bodies glowing red. This is the magic circle among the four divine dragons, and the prohibition has been activated. Each divine dragon has a magic circle passage that connects to the earth fire in the Heavenly Furnace Peak.

As the magic circle in each divine dragon was activated, the magic circle passage began to quickly hook the earth fire in the Heavenly Furnace Peak. Suddenly, four flame-monstrous fire dragons flew out from the Heavenly Furnace Peak, like four living dragons with vitality. These four fire dragons erupted from the gaping mouths of the four gilded dragons, swallowing a large amount of high-heat flames.

At this time, Ren Feiyan didn't dare to slack off, and immediately pinched and danced with both hands, * controlling the magic circle of the four gilded dragons. These circles are the key to controlling the dragon.

After Ren Feiyan's efforts, he saw that the four fire dragons that had just spit out, spitting out raging fire with their teeth and claws, like four tame monsters, began to constantly wind around the Dan furnace. The flames spewed out by the four fire dragons became more and more intense, gradually baking the huge Dan furnace hotter and hotter, and began to slowly turn red.

After Ren Feiyan saw that the flames had met the requirements, she snorted and said, "Senior Brother Lin, you can fan the fire." ”

So Lin Xiaohong, who had been on standby for a long time, hurriedly raised the No. 5 Pyrotechnician Fan, injected mana, and fanned it towards the Dan furnace from the Kan position.

As soon as Lin Xiaohong danced the large No. 5 pyrotechnic fan, he immediately triggered a strong wind to sweep towards the Dan furnace. However, the wind that looked very strong seemed to be very scattered, but as soon as it landed on the Dan furnace, it immediately gathered into thin wind insects, and did not blow to other places because of the scattering. The wind insects did not stir up much wind and waves. It just melted into the fire dragon that snaked and circled outside the Dan furnace.

With the help of the wind insects, the four fire dragons immediately became brighter, and the flames they spit out became more majestic, and they seemed to reveal a trace of golden light.

The Dan furnace, which was already red, suddenly became even more red and translucent. Some of the medicinal herbs inside began to melt. However, because there are four different materials, they have different melting points to melt.

Some are easier to melt, while others require a hotter flame and a longer time to melt. Therefore, it is up to the alchemist to control different heat conditions to smelt different medicinal materials.

When a medicinal herb is melted, it is no longer possible to increase the heat of the flame to keep it in a molten state. Then control the flame to increase the temperature to smelt other medicinal materials, and at the same time, it is necessary to control the magic circle of each grid to protect the medicinal materials that have been smelted, and prevent them from being invaded by the heat and failing. Therefore, the smelting of medicinal materials has very high requirements for the alchemist's magic circle control.

There are only a few materials needed to refine ordinary elixirs, so it is relatively easy to smelt and refine at the same time, and ordinary alchemists can do it. However, when it comes to refining a higher-grade elixir, there are countless elixirs and herbs needed, which will be even more troublesome and time-consuming, and it will be complicated and difficult to smelt at the same time.

Therefore, when refining an elixir that requires a large number of materials, the alchemist will use the split-furnace alchemy method. Although it is also possible to smelt a large amount of materials into a Dan furnace at the same time, as long as the essence of the liquid is extracted after the smelting of that material, it will be collected immediately using a special bottle of liquid that can be used in the state of essence liquid. After all the materials have been melted and purified, all the essence spirit liquid is poured into a furnace and fused to refine it into a pill.

And an ordinary elixir like the Huiling Pill only needs three or four spirit grass materials, and the requirements for the alchemist are not too high, and it can be directly smelted and refined in one furnace at the same time.

After Lin Xiaohong fanned the fire fan, the three-flavor orchid in the Dan furnace began to melt slowly, and the impurities in it began to burn continuously, flowing out of the crystal essence spiritual liquid.

So Ren Feiyan motioned to Lin Xiaohong to wave the No. 5 fire fan more to speed up the smelting and purification of the three-flavor orchid. Sure enough, the speed at which the three-flavored orchid melted was slightly faster. However, this smelting process, Lin Xiaohong can't see it. Only Ren Feiyan, who controlled the Dan Furnace Array, understood the situation inside the Dan Furnace. Lin Xiaohong could only use her spiritual power to increase the intensity of the fan.

And Li Zhaoyuan has a powerful divine sense that is different from ordinary people, so his divine sense can barely pass through the magic circle, and he can still barely see some of the situations inside the Dan furnace. But it's not him* who controls the circle, so he can't see it completely. However, he could also vaguely feel the process of smelting the spirit grass.

The essence of the essence liquid flowing out of the smelting of the three-flavor orchid exudes a special fragrance, which wafts throughout the Dan furnace room, making people feel very comfortable.

However, as Lin Xiaohong continued to increase the fan power of the fire fan, it gradually exceeded the flame temperature that the three-flavor orchid could withstand. The three-flavored orchid has a hint of burnt yellow.

Ren Feiyan immediately found that the situation was wrong, and immediately issued an order to Li Zhaoyuan: "Senior Brother Li, fan quickly!"

Li Zhaoyuan heard that it was finally his turn to make a move. So he waved his hand and danced the No. 2 banana fan continuously, and suddenly a strong wind blew out and poured into the Dan furnace from the exchange position.

Although the No. 2 pyrotechnic fan used by Li Zhaoyuan looked insignificant, the wind generated was like a wind dragon, roaring towards the Dan furnace. The wind dragon can bend and turn, and suddenly the flame of the three-flavor orchid in the Dan furnace is baked, and the other directions are rolled up, reducing the fire of the three-flavor orchid.

At the same time, the other flames turned to the grid where the other three elixirs were located under Ren Feiyan's control, causing the heat of the other grids to rise sharply. Some of the lattices also quickly reached the required heat, and the spirit grass inside also began to melt and condense and purify.

It took an hour to smelt and purify the three-flavored orchid, and it was finally completed. So Ren Feiyan controlled the temperature of the grid where the three-flavor orchid was located to prevent it from rising or lowering, maintaining the liquid essence and turning to smelt the other three materials.

With the help of Lin Xiaohong and Li Zhaoyuan, Ren Feiyan finally smelted and purified the other three materials one by one after three hours.

At this time, it was finally the critical moment for the final essence of the spiritual liquid, fused and condensed to become a pill.

Ren Feiyan took a deep breath, concentrating, and made the final preparations.

I saw Ren Feiyan pinching his fingers continuously, quickly forming four seals, and ejecting them into the Dan furnace one by one, submerging into the four grids containing the essence of the spiritual liquid.

Each grid gradually emitted a more dazzling light than the flame of the Dan Furnace, and then Ren Feiyan waved his hands, and the magic circles above the four grids were connected. The essence of the spiritual fluid in the four cells began to flow and concentrate in one place.

When all the spiritual liquid essence was gathered in one place, Ren Feiyan issued several commands in succession: "Senior Brother Lin, shake the wind and fan the wind! Fast! Senior Brother Li, control the fire in the Gen position!"

So Lin Xiaohong and Li Zhaoyuan quickly escaped to the earthquake position and the Gen position, and quickly fanned the fire fan.

And Ren Feiyan continued to dance with both hands to pinch the decision, * control the Dan furnace array, control the furnace fire, and promote the fusion and condensation of the four spiritual liquid essences into the Dan.

As Lin Xiaohong and Li Zhaoyuan continued to fan the fire fan, the four fire dragons were helped by a large amount of wind power, and they suddenly swam more happily. The flames they spit out around the Dan Furnace became more violent and hot, making the Dan Furnace even more red and clear.

Although the fire outside the Dan furnace was raging and the heat wave was rolling, the inside of the Dan furnace was under Ren Feiyan's control, and the heat was tepid and unusually calm.

With Ren Feiyan's control, the temperature in the Dan furnace is constantly changing, rising and falling. But under such a constantly changing heat, the four different spiritual essences began to slowly fuse.

While the four spiritual liquid essences slowly fused, they emitted different fragrances, which were thick and faint, and extremely weird. But fortunately, it didn't smell unpleasantly burnt.

Ren Feiyan constantly controlled the furnace fire, changing the temperature in the furnace, and saw that the four spiritual liquid essences had completely fused together. She bit her lip lightly and shouted, "Two junior brothers, increase the firepower and fan hard!"

Li Zhaoyuan needless to say, * Such a simple thing as a fire control fan is naturally extremely easy, as long as you wave it casually, there will be a large wind rolling out of the banana fan.

And Lin Xiaohong has been fanning the fire fan for several hours in a row at this time, consuming a lot of spiritual power, and she is a little sluggish for a while. This fireman boy is really not a good job. But when he heard Ren Feiyan's command, he had no choice but to stubbornly transform the remaining spiritual power into the fire fan and wave it quickly.

Only then did a large amount of wind blow out, and suddenly Li Lin and the two winds agitated, and the fire outside the Dan furnace suddenly became violent, and the temperature rose sharply.

Ren Feiyan hurriedly pinched and flipped over, injecting one seal after another. As soon as she injected the seal into it, a large amount of strange fragrance immediately came out, which smelled very good and was very comfortable.
