Chapter 4361: Fruit Shell as Furnace

Just when Zuo Feng was talking to himself to relieve his inner tension, new changes had already occurred in the medicine furnace.

Originally, Zuo Feng was paying attention to the changes in the medicine furnace in his hand. Now that he saw the changes, he immediately became more nervous. Obviously, the previous self-talk did not relieve the tension at all.

At this moment, even a little change in the medicine furnace in his hand could directly affect the overall situation, that is, the life and death of Zuo Feng himself. How could he not feel nervous?

Zuo Feng could no longer feel the changes in the medicine furnace just through the flame. He had released a wisp of spiritual energy and injected it into the fire line medicine furnace.

You must know that for Zuo Feng now, any spiritual energy is extremely precious, so Zuo Feng is unwilling to use it directly unless it is absolutely necessary.

But now, unlike before, the heat released by the flame can only touch the juice taken from the cloud grass at most, and cannot directly touch the core of the double flower vine male fruit inside.

At present, the so-called "cooking medicine" has actually begun the formal step of mixing medicine, which is equivalent to combining the treatment of medicine and the refining of medicine together.

If there is any accident now, it will directly affect the two medicines, so Zuo Feng has to pay careful attention to any changes in them.

The white juice of the cloud grass is constantly heating up in the medicine furnace, and then the medicine liquid is used to slowly stew the fruit core inside. This treatment method is relatively gentler than steaming medicine or high-temperature roasting.

The male fruit on the double-flowered vine is born in a greasy liquid, so although it looks very hard on the surface, it is actually very fragile. A slight problem will cause the entire fruit core to be destroyed, and the internal medicinal properties will be lost.

Therefore, when dealing with the male fruit core, the best way is to use the method of boiling medicine, but usually, this process is relatively long, and the person who boils the medicine cannot even practice, and has to watch over it for almost half a day.

In the process of boiling medicine, it is necessary to constantly observe the changes inside and adjust the flame to continuously increase or decrease the temperature. If the corresponding temperature is not reached, the external protection of the fruit core will not allow any medicinal properties to leak out.

However, once the temperature exceeds the limit, not only will the medicinal properties begin to be damaged, but even the entire fruit core may be destroyed. Therefore, once the temperature is too high, it must be artificially regulated to make the temperature drop rapidly.

However, if the temperature drops to a certain level, it must be raised immediately. After heating to a certain level, the medicinal properties inside the fruit core will be in an excited state. After cooling again, the medicinal properties will be combined with the fruit core itself. Then, it will be difficult to peel out the essence of the fruit core at that time.

Zuo Feng does not have so much time to slowly cook the medicine, and he must also quickly integrate the juice of the cloud grass into the fruit core, so he must always keep the temperature at the upper limit that the fruit core can bear.

In this way, not only the fusion is combined with the process of cooking medicine, but the process of cooking medicine is also greatly accelerated, and the risks to be borne are naturally greatly increased.

Since the start of cooking medicine, there have actually been several changes inside, but Zuo Feng carefully resolved them. No losses have been caused, but as time goes by, Zuo Feng can also feel that the changes that occur at any time may directly affect success or failure.

Just a moment ago, Zuo Feng felt the outer part of the fruit core begin to peel off. This change surprised him and made him very nervous.

Although the first step in the process of boiling medicine is to extract the essence inside the fruit core, it is still very rare to directly peel off the outer shell of the fruit core.

While Zuo Feng was nervous, he did not forget to carefully control the flame. In addition to lowering the temperature, he also slowed down the flow of the juice.

Originally, these white juices exerted pressure on the inside, but through continuous rotation, the released pressure was made more uniform and balanced.

However, he did not expect that the rotating and flowing juice not only made the pressure more uniform, but also continuously washed the outside of the fruit core.

In fact, facing such a change, Zuo Feng was a little unprepared. You know, the outer shell of the fruit core is indeed a part that needs to be processed, but if it is really destroyed so easily, it will have a very bad impact on his subsequent refining.

If other alchemists, faced with such a change, may be impatient to continue to remove the fruit core and get the essence inside.

However, Zuo Feng was taught by Zhuang Yu, and he had a deeper understanding of the whole process of cooking medicine.

"The outer shell of the fruit core looks very annoying, but in fact you should be grateful for its existence. It is precisely because of the outer shell that we can truly extract the essence inside without causing damage or loss."

Zhuang Yu's words would echo in Zuo Feng's mind, as if she was teaching him earnestly beside him.

For the process of cooking medicine, if you want to extract the essence inside, it is not as simple as what you see on the surface.

In fact, the outer shell of the fruit core is equivalent to a furnace in a furnace. After the external heat and pressure are applied to the fruit core, the outer shell will bear part of it, and then heat and pressurize the essence inside.

Although it seems like "taking off pants to fart" on the surface, the existence of the shell is not redundant. Because the internal essence of the male fruit is very sensitive, the heat and pressure must be controlled within a certain range when boiling medicine.

The shell of the fruit core is not only not an obstacle to boiling medicine, but an important guarantee for the entire boiling process.

When the external medicine furnace and the internal shell of the "medicine furnace" cooperate with each other, the internal essence can be extracted completely without losing the medicinal properties.

So when Zuo Feng found that the shell of the fruit core was peeling off, he was not happy at all, but became very nervous.

However, in just a moment, Zuo Feng had made a decision. First, he slowed down the rotation speed of the white medicine liquid, and at the same time reduced the pressure, but slightly increased the temperature.

Originally, the first two methods were all relief methods, but the last heating method would not help the changes in the shell of the fruit core, but would cause it to continue to deteriorate.

While Zuo Feng was regulating the changes in the internal medicine furnace, his wisp of spiritual energy responsible for detecting the situation also quietly wrapped around the surface of the fruit core.

This process may seem slow, but it is actually very fast. The adjustment of the inside of the medicine furnace and the addition of spiritual energy are almost completed at the same time.

Originally, due to the increase in temperature, the outer shell has begun to have new parts, and it is about to be peeled off from the surface, but because of the injection of spiritual energy, it is suddenly reattached.

Seeing such a change, Zuo Feng's face is not very happy, because the refining process has obviously reached a very critical time. Even if the outer shell is stabilized, the next step must be started.

After stabilizing the outer shell, the white juice is accelerated again under Zuo Feng's control, and the pressure gradually increases.

Although it is not obvious on the surface, Zuo Feng is actually in great pain now. Originally, his spiritual energy has just recovered a little, and a large part of it has to be used to stimulate the flame crystal to release the flame, and the flame has to be used to adjust the juice, pressure and temperature in the medicine furnace.

At this time, separating a part to stabilize the outer shell of the fruit core is a lot of pressure for Zuo Feng. Even the spiritual energy in the body is in danger of being exhausted again at any time.

Facing this situation, Zuo Feng naturally would not be happy. He carefully distributed the spiritual energy while trying to speed up the cooking speed.

Just when the meridians were aching and the spiritual energy in the sea was about to be squeezed out, the fruit core suddenly began to shrink. This shrinkage is not only a change in the shell, but also a change in the internal essence.

Seeing this change, Zuo Feng finally smiled. Because his efforts finally paid off, the essence was finally completely separated from the shell, and that's why it shrank.

Using the general method of cooking medicine, it would not be so difficult, but it would take at least half a day to reach this level. Now Zuo Feng has shortened this time by dozens of times, and the risk is worth it after all.

After the fruit core shrank, the most obvious change was the shell. After this period of cooking, it was no longer so hard, and because of the separation from the internal essence, the shell was now full of creases caused by shrinkage and squeezing, looking like old bark.

Originally, extracting the essence from the inside required a somewhat complicated process, but now it was directly urging the white juice, which suddenly split into several strands and rushed directly to the deepest part of the outer shell.

And each strand of the white juice was rotating on its own, like a rotating spike, directly piercing the outer shell and drilling into it.

Then the fruit core began to swell up like an inflated ball. It was even bigger than before.

After a pause of about a breath, Zuo Feng suddenly waved his hand to disperse the medicine furnace, and the flames turned into fire lines again. At the same time, juice began to fly out of the fruit core. However, the juice at this time was no longer milky white, but light blue.

The juice inside and the juice outside mixed with each other, and at the same time, the fire lines were like invisible tentacles, gently dragging the medicine liquid.

The liquid medicine was placed in a container of flames, and the temperature continued to rise. Zuo Feng took a deep breath and threw several pieces of the flower stamens of the eye-catching flower that he had just refined into the container.

"Success or failure depends on this one, there must be no problems!"

Zuo Feng stared at the changes in the liquid medicine anxiously, and even forgot to breathe.
