Although this formation also gathered all kinds of forces around it, it didn't produce huge fluctuations like a cultivator's epiphany, but only slowly gathered all kinds of forces, so it didn't attract the attention of other powerhouses of the Ye family.

It was only because of the existence of this formation that the concentration of spiritual energy around the entire secret room had greatly increased, and if there were cultivators cultivating in this range, then the cultivation speed would definitely be much faster than the usual speed.

What Ye Fan didn't know was that this small formation in his opinion was actually a very precious formation, although the level of the formation was not high, but it was only because it was not big, but the preciousness of this formation was very high.

Anyone can imagine that if there is more than one such formation in the place where the cultivator cultivates, then it will definitely increase the cultivator's cultivation speed by a large margin, but at this time, Ye Fan did not notice the purpose of this formation, he was just thinking about the specific steps of the entire refining weapon at this time.

After Ye Fan waited for a while, the concentration of aura in the entire secret room more than doubled under the effect of the formation, but when the aura increased to a certain extent, there was no longer any growth, which was precisely because of the limitations of the formation.

If the primary spirit crystals in this formation are replaced with intermediate or high-level spirit crystals, then the aura in the secret room will definitely be more powerful, and the most precious thing about this formation is that there is no need to replace the spirit crystals, because it is to absorb the aura from the outside world, and those aura will even feed back the two spirit crystals after gathering.

If this continues, after a long time, those two spirit crystals may even become intermediate-level spirit crystals, which will take a lot of time.

When Ye Fan felt that the aura in the secret room was no longer growing, he felt it with the power of his soul, and found that the aura in the entire secret room had reached about three times that of the outside world, with such a strong aura, when he was refining weapons, he didn't have to worry about the lack of fighting qi in his body, and he also prepared a lot of pills to restore his fighting qi.

Ye Fan took out the medicine tripod again and placed it directly in the center of the entire formation, this is the place where the aura of the entire secret room is the strongest, it is four or five times that of the outside world, and the refining weapon here is the most suitable.

After the medicine tripod came out, Ye Fan took out all the prepared materials, and then checked them one by one, and after confirming that there were no problems, he took out a few jade bottles, among these jade bottles, they were all pills refined by Ye Fan some time ago, and the grades were not high, most of them were first- and second-order pills, and there were only a few two or three third-order pills.

With Ye Fan's current alchemy technique, the success rate of the first- and second-order pills was already very good, but the success rate of the third-order pills was very low, and all the medicinal materials he originally purchased in the Ten Thousand Medicine Pavilion had been consumed, but the third-order pills had only been refined.

Some of the pills he refined were used to heal injuries, and the rest were used to restore fighting spirit, and he also wanted to refine some special pills, such as those that increased his cultivation speed and directly improved his cultivation, but the level of these pills was not low, and the difficulty of refining was much greater than that of ordinary pills, with Ye Fan's current alchemy technique, it was very difficult to refine such pills.

The pills that Ye Fan took out were all used to restore his fighting spirit, among them were two third-order pills, seven second-order pills, and more than ten first-order pills.

Because when refining weapons, he needs to maintain the existence of flames all the time, and he needs to consume a large amount of fighting energy, even if there is such a strong aura here, it cannot maintain his consumption, so these pills are used just in case.

After making sure that everything was ready, Ye Fan finally started his own refining, for this refining, Ye Fan attached great importance to it, once it failed, all these materials would be wasted.

You must know that although these materials are not of high grade, they are very rare, especially the three rarest materials, if these materials are wasted, then Ye Fan doesn't know how long it will take to collect all these materials.

It was precisely because of these that Ye Fan was not in a hurry to start, but began to cultivate, wanting to adjust his state to the best, Ye Fan didn't know how long he had been cultivating, when his cultivation ended, he only felt that his whole body was refreshed, and the fighting energy in his body was also surging, and his mental state was also excellent.

Feeling that his state had been adjusted to the best state, Ye Fan began his own unique refining weapon, first of all, a metal called Purple Heart Iron, Ye Fan threw the fist-sized piece of metal directly into the medicine tripod.

As soon as the purple heart iron entered the medicine ding, it was immediately wrapped in the fire of the sun, and then the fire of the sun quickly increased in temperature under the action of the soul power and fighting qi, and the appearance of the purple heart iron began to slowly soften.

Ye Fan knew that refining tools and refining medicines were completely different, when refining medicines, most of those materials were liquids and medicinal materials, and under the action of flames, they could easily be refined, and they only needed to pay attention to the degree of refining of medicinal materials at all times, so as to avoid the medicinal materials being completely burned, or the medicinal power was not completely refined, and this process did not take long.

However, refining tools are not the same, if you want to refine these metal ores and so on, it takes a long time, especially in the later stage, if you want to completely remove the impurities in the ore, you need to raise the temperature of the flame to a great extent, and this process is quite long.

This piece of purple heart iron lasted for more than four hours in the fire of the sun before it finally turned into a solution, but at this time, it did not mean that the refining of purple heart iron was completed, because in the solution of purple heart iron, there were still some impurities.

If it is an ordinary refining weapon, this is fine, but Ye Fan is not using the usual refining method, so the requirements are more stringent.

Ye Fan used the power of his soul to control the fire of the sun into several parts, each part was wrapped with a part of the purple heart iron solution, and continued to refine, which lasted for more than an hour again, Ye Fan finally saw wisps of green smoke rising from those purple heart iron solutions, Ye Fan knew that this was exactly the impurities in the purple heart iron that were formed by refining.

After another half an hour, Ye Fan found that there was no longer any green smoke coming out, and the original dark purple solution had completely turned bright purple, Ye Fan knew that this was the time when the refining was successful.

Ye Fan didn't dare to take out these solutions, because in that case, these solutions would soon solidify again, so he could only fuse those sun fires into a ball again, and then split out a ball of sun fire to wrap the solution and move it to a corner of the medicine pod.

Then Ye Fan took out a material called red mixed copper again, threw it into the medicine tripod, and started the previous step again, although red mixed copper is also a kind of copper, but its melting point is much higher than that of ordinary copper, red mixed copper in Ye Fan's refining, it took seven or eight hours to finally complete the refining.

Ye Fan's process of smelting materials is also orderly, the materials in front are the easiest to refine, and the further back, the more difficult it is to smelt the materials.

It took six days for Ye Fan to finally smelt most of the materials, leaving only the three most important materials, that is, the most precious materials among them, Star Pattern Silver, Sun Stone, and Star Platinum.

After six days of refining, Ye Fan's spirit was extremely consumed, and his soul power had been consumed by more than half, only the fighting qi in his body was still good, and with the support of four times the concentration of spiritual energy and pills, the fighting qi in his body was always maintained at seven or eighty percent.

It's just that in the refining process of the past few days, Ye Fan has been working hard to recover, and at the same time, he has continued to use it, so that his fighting qi has continued to grow unconsciously, and his fighting energy has become more refined in the continuous consumption and recovery.

Ye Fan picked up the water bag beside him and poured a big sip into his mouth, and suddenly felt a little better, with Ye Fan's current strength, he didn't eat for ten consecutive days, relying on his fighting spirit and body to support, but it was completely impossible without water, especially if he stayed next to the sun fire, even if Ye Fan didn't care about the temperature, it would still affect the loss of water in his body, so he needed a lot of water every day to maintain his physical strength, but fortunately, he had prepared a lot of water before refining the weapon.

After drinking the water, Ye Fan looked at the medicine tripod, at this time, the twenty-four materials that had been smelted were all wrapped in a ball of sun fire, scattered in all corners of the medicine tripod, originally these more than twenty kinds of materials were put together in a pile half a meter high, but after refining, all the impurities in it were melted, and some of the useless substances were all eliminated by Ye Fan, and now the rest add up to only the size of a volleyball.

Ye Fan took a breath, cheered up, then picked up the star-striped silver and threw it into the medicine tripod, Ye Fan knew that although there were only three materials left, the smelting and final refining of these three materials were much more troublesome than those that had been done before.

Although there is a star in the name, the star silver has no meaningful relationship with the stars, and the energy contained in it is actually the power of the moon, just because the star silver is also a material in meteorites, but the power of the moon and the power of the stars in the meteorite are completely different, so whenever someone finds a meteorite, the star silver will be found next to it.

This is because when the meteorite hits the earth, it scatters all the star-striped silver around, so many people think that the star-striped silver is the companion of the meteorite, but this is actually wrong, the star-striped silver itself is a part of the meteorite, and it is only because it absorbs the power of the moon yin, so it will be dispersed from the rest of the meteorite.

The smelting of star-striped silver can't be completed with the fire of the sun, which will make the power of the moon yin in the star-striped silver completely dissipate, so when Ye Fan threw the star-striped silver into the medicine tripod, he sacrificed the fire of the sun at the same time, and only the fire of the sun can perfectly preserve the power of the moon yin in the star-striped silver.
