The pill taken by the cultivators of the Fetal God Realm for their daily cultivation is called the Returning God Pill.

The main medicine of the refining of the Returning Pill is a high-level medicinal material called the Returning Divine Herb, which is also named after this.

However, the refining of high-grade elixirs is different from that of medium- and low-rank.

The amount of excipients will also occupy an extremely important position in the refining process of high-grade pills.

Take the Returning Pill as an example, if you want to open the furnace to refine such a furnace of high-grade pills.

In addition to the main medicine of the rejuvenating herb, there are as many as 36 kinds of auxiliary medicines that need to be prepared.

After all, in terms of value, these adjuvant lists have surpassed the main drugs of middle-grade pills.

And from these raw materials, it can also be seen that the basic value of a furnace of high-grade elixir.

However, this is not all, the preciousness of high-grade elixirs is far beyond ordinary people's imagination.

One of the important reasons is that the extremely low rate of Cheng Dan is incomparable.

And this is also the most outrageous point of refining high-grade pills.

The basic success rate of the Returning God Pill is only one percent, and this is not bad.

If the pill taken by the Yuanjue Realm cultivator was refined, then the basic pill rate would not even be 10%.

And under the effect of the rate of returning to the god pill to become a pill, he wants to pile up the alchemy skills through a large number of refining.

The cost of this will be astronomical.

In the face of such losses, it is difficult to say that the ordinary forces can hardly bear it.

Even if it is a master with blood, it is difficult to eat.

After all, there is a limit to the number of plant samples that can be recorded in the blood.

Even if Shi Yi removed all the recorded Climbing Trees, Yin God Wood Roots, and Ghost Umbrellas, all of them were used to record the medicinal materials needed to refine the Returning God Pill.

In the face of as many as thirty-six precious adjuvants, Shi Yi had no way to record them all in his blood.

What's more, with the Yin God Wood Roots, there is still the value of the ghost umbrella.

Rashly removing them from the ability to eliminate the blood is definitely not worth the loss.

In addition, the most troublesome aspect of high-grade herbs is that they cannot be stored for a long time after being picked.

Although high-level adjuvants are not like the main drugs such as rejuvenating herbs, the loss of medicinal properties after picking is extremely fast.

However, the slow and slow flow of adjuvants is also real.

If the Rejuvenation Herb loses its medicinal properties in three days, then the thirty-six high-grade adjuvants can only last for half a month at most under normal conditions.

It was such a harsh time limit that made high-level cultivators need to regularly look for high-level herbs to complete the elixir refining in the near future.

And Shi Yi grasped this point back then, and took advantage of Fang Yinchuan to look for medicinal materials every month.

This fixed itinerary was a breakthrough, and it was blocked in the secret place of the lotus pond.

The low rate of pills and the easy loss of medicinal properties doomed high-grade pills to be produced in batches like refining medium- and low-grade pills.

For high-level cultivators, the refining of each furnace of high-grade elixir took considerable effort.

And the time of a high-level monk is so precious, it is not easy to regularly take time out to go to the secret place to collect the medicinal materials used in alchemy.

If you still fail to refine repeatedly, then you really don't have to do anything, and you can be a medicine picker full-time.

The pill is a means to make the cultivator cultivate faster.

If you put the cart before the horse, then the gains outweigh the losses.

So, in order to ensure the rate of Cheng Dan.

When refining high-grade pills, they can only be assisted by means such as Fu Xiang to increase the success rate.

Fu Xiang is a high-level talisman that can reverse cause and effect, and the effect is naturally outstanding.

However, the value of a high-level talisman with such an effect cannot be low.

As a result, this further raised the value of high-grade pills.

It can be said that every time the furnace is opened to refine high-grade pills, it is burning money in the real sense.

However, the elixir is a necessity for the monk's daily cultivation.

No matter how expensive it is, it will not hesitate to go bankrupt when it is time to refine.

It is also the rare status quo of high-level pills, most of which exist in the high-order world, and they are maintained at a relatively low amount of pills on a daily basis.

By analogy, Chen Ran's chronic illness was caused by the lack of pills and medicines back then.

The condition of the high-level monk's elixir today is actually similar to that of Chen Ran back then.

Although it is not like Chen Ran who has eaten the last meal and has not eaten the next meal, it is even more impossible to harm himself like Chen Ran.

However, most high-level cultivators really didn't fill up the amount of high-level pills.

If you can take it vigorously, a high-level existence can eat a force out of poverty.

It is this embarrassing status quo that makes there be a customary rule between various high-level forces.

That is, as long as they reach the high level, the power will no longer bear the cost of cultivating the pill for the high-level cultivators.

Although this kind of regulation has reduced the burden on the power side, it has also caused dissatisfaction among the high-ranking power members.

After all, in the middle and lower ranks, between the monks and the forces, the pay and the gain are equal.

And after reaching the high level, the monk seems to have only one thing left to give.

Of course, each has its own difficulties, and we will not list this matter.

All in all, the difficulty of refining high-grade elixirs and the degree of preciousness were completely proportional.

However, this time Shi Yi seemed very casual.

Shi Yi didn't even prepare a prop like Fu Xiang to increase the success rate, obviously preparing for strong training.

After placing the Dan furnace properly, Shi Yi took out a bunch of medicinal materials from his storage pocket and threw them on the table.

I saw that the herbs of different shapes were thrown away by Shi Yi to fill a large table.

If you count carefully, you can see it right away.

There are a total of thirty-six of these herbs on the table, and none of them are duplicates.

Obviously, these medicinal materials are exactly what I said before, which are used to refine the adjuvant pill of rejuvenation.

The advantage of high-end adjuvants over high-end main drugs is that they are not so demanding on the environment, and they can be cultivated artificially.

However, as long as there are high-level cultivators, they need to open up a medicine garden to grow these auxiliary medicines.

After all, the refining of high-grade pills was left behind.

If you don't put some effort into these adjuvants.

Then, the high-level under the door is estimated to really scold the mother.

The cultivation forces planted auxiliary medicines, and naturally it was impossible to plant just enough quantities.

After all, the world is impermanent, and no one can guarantee that there will be no accidents.

So, in general.

The output of the medicine gardens where the Xiuzhen forces planted auxiliary medicines was far greater than the demand of the high-level of the sect.

And auxiliary alchemy methods such as Fu Xiang basically ensure the success rate of high-grade pills.

As long as this kind of means are cooperated, the waste of raw materials can be basically eliminated.

In addition, the extremely high value of means such as Fu Xiang is generally difficult to see, and large-scale alchemy appears in a short period of time.

The above two points are doomed, the auxiliary medicine planted by the Xiuzhen force, under normal circumstances, will generally have a large surplus.

As mentioned before, whether high-grade medicinal materials are main drugs or auxiliary drugs, their medicinal properties will continue to be lost after picking.

The only difference is that the loss rate of adjuvants is slower than that of the main drug.

And every plant, there will always be a day when it will mature.

If these excipients are not picked after they have matured.

The end result is nothing more than withering in the medicine garden and turning into fertilizer.

After harvesting, the loss of medicinal properties also eliminates the possibility of long-term storage.

In the end, in order to stop the loss, the Xiuzhen forces could only choose to sell these auxiliary medicines.

As a result, a very interesting phenomenon has emerged in the market.

High-end adjuvants are very easy to buy, but they are middle-end main drugs with slightly lower value, but they are rarely seen.

And, over time.

The price of these excipients will also fly down like a dive.

The status quo of high-level adjuvants is not as good as that of middle-level main drugs, and the number of high-level monks among them is scarce.

and the characteristics of the loss of medicinal properties of high-order medicinal materials, and many other factors.

However, this is cheaper for a high-level casual cultivator like Shi Yi.

These are all auxiliary medicines on the table, and they were all bought by Shi Yi in Fan Guo before leaving.

Now, several months have passed since Shi Yi left Fan Guo.

It stands to reason that the properties of these excipients should have been lost.

However, Shi Yi used the extremely cold ability of his ice path to completely freeze these medicinal materials.

Almost fundamentally, the loss of medicinal properties has been eliminated.

At this time, if there is an alchemist who knows how to refine high-level pills here, he will definitely scoff at Shi Yi's behavior, and bluntly say that Shi Yi is a layman.

Although freezing can prevent the loss of medicinal properties, it will also change the properties of the medicinal materials themselves under the action of extreme cold.

For example, under the effect of cold air, the original water contained in the herbs will be different.

After all, in the process of freezing in the cold.

Inevitably, the moisture in the air will also be frozen on the plants.

Take 10,000 steps back, even if there is no moisture.

However, the Ice Dao was originally a branch of the water attribute school, and the water attribute Heaven and Earth Yuan Qi during the freezing process would also produce a similar effect when invading medicinal materials.

In the process of alchemy, the most important point is precisely the control of the heat.

The invasion of the water attribute heaven and earth vitality into the medicinal herbs will increase the difficulty of controlling the heat.

Even if the cold qi dissipates, the infiltration of the water attribute heaven and earth vitality cannot be eliminated in a short period of time.

These frozen adjuvants do not seem to have lost their medicinal properties.

However, for the other alchemists, they were all completely abolished.

It is precisely for the above reasons that no one generally uses cultivation methods such as the Ice Dao to preserve alchemy medicinal materials.

Most of the time, alchemists only use warm cultivation methods such as jade boxes to slightly reduce the rate of loss of medicinal properties.

From this point of view, Shi Yi is indeed a bit of a layman.

However, these are all intentional by Shi Yi.

After all, Shi Yi's alchemy time is not short.

For these precautions for alchemy, I naturally know it.

The reason why Shi Yi did this was because he was refining high-grade pills by himself, and he didn't need to consider factors such as heat at all.

For a long time, the blood-burning ability has not played its greatest role in Shi Yi's hands.

It can be said that using burning blood in battle is completely overkill.

When he got the ability to burn blood, Shi Yi once imagined it.

Apply the blood-burning ability to refining high-level elixirs to reduce the difficulty of refining elixirs.

After so many years, Shi Yi has long verified that this method is indeed feasible.

Now, Shi Yi is planning to repeat this step.

I saw Shi Yi knock the Henggu Stone on his chest with his fingers, and then the fat chirp flew out of the Henggu Stone.

Its fat sparrow appearance has not changed, but this is only a superficial appearance.

Decades have passed, and Fat Jiu has passed his infancy, and he can be regarded as a spirit animal that has entered his youth.

If the original form is revealed, the room prepared by Chaoyin Pavilion for Shi Yi may not be able to accommodate it.

Therefore, most of the time, Chubby Jiu still maintains the original sparrow appearance.

Retaining the original should be the ability of the later beast.

After all, there is no concept of growth in the post-beast.

They are what they were from the moment they appeared.

Obviously, Fat Jiu's ability to maintain its original appearance stems from the bloodline of the post-beast on its body.

That's it, after flying out of the Henggu Stone.

The fat chirp naturally landed on Shi Yi's shoulder, and rubbed Shi Yi's neck with his little head very affectionately.

Shi Yi also took out the yuan crystal casually, and crushed it for the fat chirp to peck.

In just a moment, Fat Jiu ate the Yuan Jing in Shi Yi's hand.

After that, the satisfied chirp twice.

Since you have enough to eat, you naturally have to work.

At Shi Yi's signal, Fat Jiu aimed his eyes at the Dan furnace, and the pupils in his small eye sockets turned violently.

Then, the surrounding temperature rose sharply, and the entire Dan furnace burst into flames.

The temperature required for the refining of high-grade pills was no longer something that could be achieved by ordinary fire.

Although the flames released by the blood-burning ability are powerful, they are still somewhat meaningless.

And as a spirit beast with phoenix blood, the firepower that Fat Jiu can generate when he becomes an adult is no small thing.

In terms of temperature, it is only high, not low.

Seeing that the Dan furnace had been burned red under the action of the fat chirp flame, Shi Yi couldn't help but nod with satisfaction.

At this time, Shi Yi cut his wrist and sprinkled his own blood inside and outside the Dan furnace.

Then, Shi Yi directly activated the blood-burning ability.

In this way, the flames from the burning blood also burst out at once.

For a moment, the bright yellow flame of burning blood was intertwined with the dark red flame of Fat Chirp.

In terms of firepower alone, Burning Blood is obviously inferior to Fat Chirp Flame.

However, Burning Blood has the property that does not go out.

Therefore, the dark red flame did not burn blood for a while.

On the contrary, it is constantly eaten away by burning blood.

Soon, part of the blood-burning flame had the high-temperature characteristics of a dark red flame.

Then, at the signal of Shi Yi, Fat Jiu stopped the release of flames, which further aggravated the cannibalization speed of burning blood.

After all, fire is a source of energy that needs to be replenished.

If there is no object to burn, there is no supply of fat chirps.

No matter how powerful it is, extinguishing it is a completely doomed result.

Burning blood, on the other hand, is an existence that completely violates the characteristics of flames......
