The rules of heaven seem complicated and profound, but in fact, there are traces to follow.

Everything in the world, no matter what form it takes, hardly changes the energy attributes that belong to its essence.

To put it simply, you can change a life, but you can't create a life out of nothing, because creating life is something that only the legendary creator can do.

In essence, alchemy medicine is actually a material reorganization, removing impurities and retaining essence, so that the original attribute energy can be completely volatilized and used by people.

The reason why Alchemy Pharmaceutical places special emphasis on the Ding furnace is because in the process of refining, the attribute energy of the material will be lost and volatilized, but the Ding furnace can inhibit this process. If some formations are engraved on the surface of the Ding furnace, it can even strengthen the medicinal properties.

However, the common Ding furnace is almost always carved on the outer wall, and few are directly carved on the inner wall.

The difficulty of the technique is one thing, but the most important thing is to integrate with each other.

This kind of formation specially used to strengthen the medicinal properties is actually a kind of energy flow guide map, if the inner and outer walls of the Ding furnace are depicted, it is very likely that the effect will be greatly reduced due to mutual exclusion and cancellation.

Unless...... The inner wall and the outer wall are carved in the same formation.

But is it possible?

At least Ye Chen had never seen it.

Ye Chen took Xiao Ding in his hand, sacrificed a divine sense and went deep into the inner wall to observe, and did not let go of any formation trend route.

But soon, Ye Chen was disappointed.

It wasn't at all what he had guessed, the formation on the inner wall was another formation entirely, and there was no resemblance to the formation on the outer wall.

Moreover, Ye Chen couldn't understand the formation carved on the inner wall.

It's not that the formation inside is extremely complicated, but the formation on the inner wall only has nine lines, which is simple and clear.

When Ye Chen was in the Crescent Moon Continent in his previous life, he thought that he was extremely talented, well-read and memorized, and knew everything about the formations in the world, but at this time, he searched hard in his mental memory, but he just didn't find this extremely simple formation record.

Until the end, Ye Chen even had doubts about whether this was a formation or not, he was thinking too much about himself.

However, this idea was quickly rejected by him, this Ding Furnace will definitely not be so simple, from being able to transform into a small bead can be glimpsed one or two.

Ye Chen studied inside and out for a long time, but in the end he found nothing and had to give up.

"No matter, let's try the effect first."

Although the specific role of the formation inside has not been figured out, fortunately, the formation on the outer wall is still there, although it is slightly damaged, but the impact on alchemy should not be very large.

After cleaning Xiaoding inside and out, Ye Chen pushed the door out and went straight to the kitchen.

The simple heat source such as the alcohol lamp he used to use for alchemy naturally couldn't be used to heat Xiao Ding, and Ye Chen was even worried that it was difficult to say whether even the gas stove could be heated.

The heating here does not refer to an ordinary heat source, but a special heat source that can allow the Ding furnace to excite the formation for smelting.

But now I have to try it first, Ye Chen turned up the fire of the gas stove to the maximum and put Xiao Ding on it.

Immediately, Ye Chen's wrist flipped, and a flavor of medicinal herbs appeared on the table out of thin air, as many as a dozen flavors.

With the increasing sophistication of cultivation and the gradual strengthening of physical fitness, Ye Chen decided to refine the Purifying Pill of a higher level than the Yijin Pill, the refining formula of the two pills is actually about the same, and the auxiliary medicinal materials are basically the same, but the main medicinal material for refining the Purifying Pill is not phoenix gall, but another medicinal material, which is called King Kong Teng in the terminology of this world.

The main function of the Pulp Cleansing Pill is to widen the muscles and veins, increase the power of the stars, and increase the speed of a series of auxiliary functions.

Ye Chen is also preparing for the future, he plans to collect all the materials needed, he is ready to refine the Resurrection Pill, only one is needed, he can break through to the third second life of the "Ten Folds Longevity Formula" in one fell swoop, and at that time his strength will make a qualitative leap.

However, the main medicinal materials for refining the Resurrection Pill are all sky-high, and they are still the kind that have no price. This is also the reason why Ye Chen has been shouting poor recently. It's no wonder that Xue Ziyi always said that he fell into the eyes of money......

Dude am I easy, buddy?

Ye Chen thought about it for a while, didn't think about it anymore, gathered all his thoughts and began to refine the Purifying Pill.

Put the medicinal herbs into Xiao Ding one by one, and in a moment, Xiao Ding began to make a buzzing sound, and at this time, Ye Chen was really relieved, fortunately, the ordinary heat source could be used.

Ye Chen looked inside Xiao Ding, only to see that the seven or eight flavors of medicinal materials in it were slowly deformed, and in a short period of time, they were calcined into a mass of inky black viscous liquid, reflecting a faint luster.

The key to refining medicine is to control the fire, and the steps are divided into three steps, condensing the liquid, removing impurities, and fusing with each other.

What Ye Chen is doing now is still the first step to condense the liquid.

The divine consciousness was released into the ding, sensing the changes in the medicinal liquid. At the same time, Ye Chen carefully controlled the size of the fire, at this critical moment, as long as the temperature deviated slightly, this inky black liquid would turn into waste residue.

Slowly heated, and finally, a little white substance suddenly appeared in the inky black liquid.

Ye Chen understood that it was an impurity.

He immediately slapped the outer wall of Xiaoding with his right hand, and under the power of the stars, Xiaoding suddenly hummed. At the same time, a wisp of Ye Chen's divine consciousness quickly cut in, removed the white impurities, and wrapped it in his divine sense and moved out of Xiaoding.

These steps, which are carried out almost simultaneously, require extreme precision, but if there is the slightest deviation, the medicinal materials may be scrapped.

After removing this mass of white impurities, some small pale white impurities appeared one after another, and these impurities were all quickly cleaned up by Ye Chen without exception.

At the same time, the inky black liquid became more and more viscous, but instead of blending together, it seemed to repel each other, and divided into particles about the size of soybeans, like black pearls, dazzling.

Ye Chen's eyes swept away, there were hundreds of drops, in this way, at least five marrow cleansing pills could be refined.

After more than ten minutes, when there were no more white impurities on the inky black object in the ding, Ye Chen quickly grabbed King Kong Teng in his hand, and the power of the stars in his hand was triggered, and King Kong Teng instantly turned into a pile of fine powder, scattered from his fingertips in the ding.

Suddenly, these powders were like fireflies in the dark night of summer, emitting a cold fluorescence, scattered on hundreds of droplets, like stars in the dark night, dotted on them.

Phew! Phew!

King Kong Teng's powder was like a ball of adhesive, and when several incompatible liquids touched, there were bursts of strange sounds, and a faint white mist rose from the ding.

After the white mist weakened, Ye Chen saw that the hundreds of droplets in the original Ding were grouped together every twenty drops, and they began to merge rapidly, and the speed was very fast, and in the blink of an eye, five rough rudimentary pills were formed.

Seeing this scene, Ye Chen's face was slightly happy, but he didn't dare to slack off.

Immediately, with a low cry in his mouth, the power of the stars in his body began to surge, speeding through the meridians, and as his two arms danced one after another, the flickering dark red stars continued to wrap and roll on his hands.

Subsequently, Ye Chen's hands continued to seal, making a series of mysterious handprints, and a little light burst out from his hands, and then became more and more brilliant, and finally with the wave of his hands, all of them were poured into the outer wall of Xiaoding.

Airplanes!

Suddenly, Xiao Ding trembled slightly, and the formation carved on the outer wall suddenly brightened, and colorful rays of light bloomed out.

The rainbow glow flickered five times in a row before it finally disappeared, and it was extremely fast. If an outsider saw this scene at this time, he was afraid that he would be stunned and speechless.

The next moment, the rich medicinal fragrance began to permeate the air, which lifted Ye Chen's spirit.

A few traces of joy crossed Ye Chen's face, he knew that he had succeeded, and it was a success.

However, after thinking about it, Ye Chen was immediately relieved, after all, they were all low-grade medicinal materials, and the techniques were relatively simple, and it was not impossible to succeed at one time.

The formation on the outer wall of Xiao Ding flashed five times just now, which also indicated that five pills had been formed.

Sure enough, Ye Chen looked down and saw that at the bottom of Xiaoding, five round yellow pills were lying there quietly.

Ye Chen stretched out his hand and took one of the pills in his hand to look at it, and his eyes widened suddenly.

I saw that on this thumb-sized elixir, there was a faint circle of milky white ripples, like ripples in the water, which looked quite strange.

Danwen?

Looking at the pale white ripples, Ye Chen was a little dazed.

In refining pills, it is usually when the color and grade of the refining materials have reached the peak that the pill pattern may appear. And it's just possible, it's not certain, anyway, when Ye Chen was in the Crescent Moon Continent in his previous life, he had never practiced a pill with a Dan pattern on it.

This alchemy has been successful more than once, and the medicinal materials used to refine the medicine are not treasures, but it is rare to practice the pill with a Dan pattern. This made Ye Chen himself feel a little unbelievable, could it be ......

Wait, is this the reason for this?

Thinking of this, Ye Chen hurriedly looked down, and for a moment, he was dumbfounded!

Since he came to this world, there were few things that surprised him, but the scene in front of him almost subverted Ye Chen's previous cognition.

I saw that one of the pills in Xiao Ding, as if it had encountered some kind of chemical reaction, was melting at a speed visible to the naked eye, and in the blink of an eye, it quickly became smaller, and then disappeared completely!

Immediately afterwards, there was the second one, the third one, and the same, Ye Chen was dumbfounded.

Could it be that the elixir that was finally practiced was still devoured and eaten by this ding?

Ye Chen pondered for a while, he had never encountered such a vision in his previous life, and he was on the spot for a while.

Ye Chen once again looked at the nine lines on the inner wall of the tripod, and found that these lines had become clearer, extremely bright, and shimmering with a faint luster.

Ye Chen stared at these lines, and suddenly a flash of inspiration flashed in his mind, and he suddenly remembered a legend on the Crescent Moon Continent......
