With both hands clenched, the flames of the earth that rose in Zhao Yi's palms disappeared. By learning from the memories of Lan Hao, the old man with a white beard, Zhao Yi knew that refining medicine was an extremely energy-consuming thing, and he had to have a high degree of concentration in order to refine the elixir.

The first key to refining medicine is to control the fire, and only by controlling the flame like a finger will there be divine help when refining the pill.

Alchemists are all fire attribute internal qi, and ordinary alchemists transmit the internal qi to the medicine tripod, and then use the power of the medicine tripod to turn the fire attribute internal gas into flames, so as to refine the elixir, and some powerful alchemists can refine a certain flame power between heaven and earth, so that they can emit flames, and when refining the pill, they can save a lot of internal qi.

And Zhao Yi, although the internal qi does not have any attributes, but he who has refined the fire in the center of the earth, in terms of flames, he has to surpass most or even all the alchemists!

Before starting the alchemy, Zhao Yi decided to practice the control of the flames first.

Zhao Yi's hands each rose a ball of earth-centered fire, exuding a scorching heat. These two flames flickered big and small, turning into the shape of a unicorn for a while, and turning into the appearance of a giant dragon for a while, and they were extremely powerful.

With Zhao Yi's soul power, which is now comparable to the peak of the Xuanzun Realm, it is still extremely easy to initially control the flames.

"The most important thing in the control of the flame is the temperature, because the temperature of the alchemy is the most strict, no matter whether the temperature of the flame is slightly higher or a little lower, it will lead to the failure of the final alchemy. From the "Ancient Method of Alchemy", Zhao Yi knew what the most important point of alchemy was.

After practicing flame control for a day, Zhao Yi realized that he was already able to control the flame temperature with great ease, so he took out a few elixirs from Xisu and prepared to start his first refining!

The three first-order elixirs that Zhao Yi took out were all green, one of them, the stems and leaves were extremely delicate, the leaves of the other elixir were like jade pearls the size of beans, and the third elixir was very ordinary, and it didn't look special.

These three elixirs are exactly the materials needed to refine the Yipindan's Qi Gathering Pill. They are Huilu Grass, Spirit Bead Grass and Ban Grass, these three elixirs have a certain effect on the recovery of internal qi, and Zhao Yi is preparing to use these three elixirs to refine the Qi Gathering Pill.

Qi Gathering Pill has a very strong effect on the recovery of the internal qi of the martial artists of the Acquired Realm, and when the outer disciples of the Xingyun Sect go out to practice, they will carry one or two bottles of Qi Gathering Pill in case of emergency.

According to the records of the "Ancient Method of Alchemy", the first step in refining medicine is to use flames to refine the essence of the elixir.

Zhao Yi took a deep breath, and then threw the Huilu grass into Zhanshui Ding first. Zhao Yi's left palm was against the tripod's body, and the internal qi was transmitted into it, stimulating the power of Zhanshui Ding, and this time the dew grass was slowly suspended in Zhanshui Ding.

Then, with a wave of Zhao Yi's right hand, the fire in the center of the earth in his palm fell into the Zhanshui Ding, and slowly approached the suspended Huilu grass.

With the scorching fire in the center of the earth, the dew grass gradually began to wither and concentrate, and after a while, the medicinal essence of the dew grass was about to be refined.

"It's so easy!" Seeing this scene, Zhao Yi couldn't help but be overjoyed, and the strength of the flames output couldn't help but increase a little.

"Poof!"

In just one moment, the Huilu grass that was about to be refined into the essence of the Zhanshui Ding was instantly burned into fly ash and fell into the bottom of the Zhanshui Ding!

"Well, I'm excited, I'm excited, I have to calm down, calm down, and I have to have no waves in the ancient well. Looking at the black ash at the bottom of Zhanshui Ding, Zhao Yi erected a few black lines on his face and secretly admonished himself.

After cleaning up the black ash from the Zhanshui Ding, Zhao Yi quickly adjusted his mind, and then took out a back-dew grass from the Xisu and threw it into the Zhanshui Ding.

According to the tips mentioned in the "Alchemy Ancient Method", Zhao Yi was more careful to refine this Huilu grass.

Sure enough, under this careful refining, it didn't take long for Zhao Yi to refine all the medicinal essence of this Huilu grass, and the entire turquoise Huilu grass had turned into a milky white medicinal essence at this moment, quietly suspended in the medicine pod.

Zhao Yi's left hand on top of the medicine tripod once again increased the output of internal qi, and Zhanshui Ding then released a force that isolated the essence of this cloud of rejuvenating grass to the side.

Subsequently, Zhao Yi threw the second elixir, the Spirit Bead Grass, into the Zhanshui Ding.

The golden-red flame of the earth's core rose again, burning quietly, refining the second elixir used to refine the Qi Gathering Pill.

The resistance of the Spirit Bead Grass to the flames was slightly weaker than that of the Returning Grass, and Zhao Yi didn't pay attention to it, and the temperature of the output of the Earth's Core Flame was a little higher, and he directly burned this Spirit Bead Grass to ashes.

Zhao Yi didn't care about this, but took out a spirit bead grass from Xisu again and threw it into Zhanshui Ding to continue refining.

After all, this is the first time he has tried alchemy, and it is inevitable that there will be some shortcomings, and the white-bearded old man Lan Hao should have realized this before, and the amount of elixir prepared in Xisu is very sufficient, enough for Zhao Yi's practice!

Zhao Yi wholeheartedly refined the medicinal essence of the elixir, even if there was a mistake in the refining process, his mind did not fluctuate for half a minute, but continued to refine, and finally after losing five elixirs, Zhao Yi finally refined a medicinal essence of each of the three elixirs, which were isolated in Zhanshui Ding.

"This refining medicine is really not easy!" After refining the essence of the three elixirs, even with Zhao Yi's strength, his forehead was covered with a layer of fine sweat at this moment, after all, refining the elixir, in addition to the consumption of internal qi and soul power, the loss of the mind was also not small.

However, refining the essence of the elixir is only the first step of refining the elixir, and the next step that needs to be faced is the most difficult and important step, that is, to fuse the essence of these three elixirs together, so that they are not separated from each other. After that, you can move on to the next step!

Zhao Yi followed the record of the "Alchemy Ancient Method", increased the output of internal qi, mobilized the functional power of Zhanshui Ding to slowly bring the three groups of medicinal power essence closer, and at the same time, the output of flame in his right hand also continued, refining and fusing the three groups of medicinal power.

However, just when Zhao Yi had just raised the temperature of the earth's core flame and wanted to refine and fuse the three clusters of medicinal power essences, a slight explosion suddenly sounded in the Zhanshui Ding, and then, a thick cloud of gray smoke rose from the Zhanshui Ding.

"Phew!"

Zhao Yi couldn't react for a while, and was hit in the face by this cloud of gray smoke, and his handsome face instantly turned into a piece of black charcoal, looking extremely embarrassed and funny.

"It's really a big head, but it's just a small elixir, it's impossible for me to admit defeat!" Zhao Yi snorted lightly, adjusted his state, and then took out three elixirs from Xisu and continued to refine them.

With the refining experience just now, Zhao Yi did not fail too much in refining the elixir this time, only lost one slab grass, and refined all the medicinal essence of the three elixirs.

Zhao Yi worked hard to adjust his mind, just now he failed in this step, this time, we must learn the lesson just now and successfully complete this step!

As Zhao Yi transmitted his internal qi, the three groups of elixir essences in Zhanshui Ding slowly approached each other again.

Zhao Yi learned the lesson of the last time, and did not raise the temperature of the geocentric flames to a very high level, lest they turn into ashes again.

Sure enough, this time there was no explosion in the Zhanshui Ding, however, it was also unsuccessful.

It's just that the temperature of the flame is not high enough, and the medicinal essence has not yet fused together, so it is scattered into a mess.

"I don't believe it, this little pill can still be difficult to hold me?" The two successive failures not only did not discourage Zhao Yi, but aroused his stubbornness, and immediately Zhao Yi continued to take out the elixir from Xisu and put it into Zhanshui Ding to continue refining.

This time, Zhao Yi did not lose any of the elixirs, and refined all the medicinal power essences of the three elixirs.

Although he did not succeed in this step of fusing medicinal essence, Zhao Yi was already very proficient in refining the medicinal essence!

However, soon, this third fusion still failed, and the reason was because the temperature of the flame was a little higher, so there was no explosion this time. But the medicinal essence also slammed and turned into black ash!

Zhao Yi was not discouraged, and even prepared for many failures, and refined ten medicinal essences at one time for later use!

The fourth time, bang!

The fifth time, poof! failed.

The sixth time, boom! failed.

The seventh time, smack!

The eighth time, whew! failed.

He failed five times in a row, and it wasn't until the ninth time that Zhao Yi fused the medicinal essence of the three elixirs together. The medicinal essence of three different colors is fused together to present an emerald color, which looks crystal clear and extremely pleasant.
