Defying the Martial Way to Burn the Heavens

Cloud grass itself is not a top-level medicinal material. Even if it is ranked among the intermediate medicinal materials, it is a bit reluctant. One of the important reasons is that there are too few parts of cloud grass that can really exert medicinal properties, only a little bit inside.

The first step in refining medicine is to refine the medicinal materials and extract the required essence from them. When extracting the essence of cloud grass, it is actually a test for the alchemist, because the essence of cloud grass is concentrated in the juice of the grass stem.

It often takes three to four cloud grasses to extract a very small drop of milky white liquid, which is the real medicinal property of cloud grass.

However, because the nature of cloud grass is cold, flames are needed when refining, which is a big test for alchemists.

Because the control of flames is not detailed and accurate enough, it is very likely that the liquid medicine will evaporate at high temperature. In addition, it is possible that the flame power in the flame will invade the liquid medicine of cloud grass, directly destroying its cold property, which will also make the liquid medicine lose its medicinal properties directly.

So don’t look at the low quality of cloud grass, but using it to refine medicine, the requirements for alchemists are definitely not low.

However, Zuo Feng is different from ordinary alchemists. He not only has a good grasp of the medicinal properties of cloud grass, but also has unique methods to extract the essence of its liquid medicine.

Zuo Feng's foundation of alchemy was taught by his master's wife Zhuang Yu, which is a unique method of mixing medicines in the Yao family of Xuanwu Empire. Even in the Yao family, only a very small number of core figures know this method.

Compared with the general method of making medicinal powder, the mixing method can better bring out the medicinal properties, and the medicinal powder refined can also preserve the medicinal properties for a longer time.

During the period when Zuo Feng was unable to practice, he concentrated on learning the method of mixing medicines with his master's wife, and started from the most basic. The real difficulty of mixing medicines lies in the mastery of the characteristics of medicines. Cloud grass is a lesson to practice the mixing method.

Ordinary alchemists refine it by tempering it little by little through the furnace fire, while the mixing method is to extract the liquid medicine from the cloud grass through steaming, boiling and exposure to the sun, combined with a series of methods.

In the past, Zuo Feng could only be sure that the essence of the medicinal liquid in the cloud grass was located in the grass stem near the root. It was not until today, when he faced the giant tree-like cloud grass and used his last strength to tear off the surface, that Zuo Feng knew what the inside of the cloud grass looked like.

Inside the cloud grass, there are countless fine "pipes", which seem to provide nutrients for the growth of the cloud grass. As for the pipes inside the cloud grass, 99% of them are light green, and only one is light yellow.

Zuo Feng almost immediately confirmed that this was what he was looking for after he peeled off the outer wall of the cloud grass stem.

Zhuang Yu once told Zuo Feng that the juice in the cloud grass could hardly be used, and could not be mixed with the essence of the medicinal liquid of the cloud grass, otherwise a cloud grass would be useless.

With ordinary means, it is impossible to forcibly extract that part of the medicinal liquid essence without mixing it with other grass juices, so in addition to using flame extraction, it can only be extracted by mixing medicines.

Zuo Feng not only likes to use his brain, but is also very willing to try. He once tried to extract the essence of the liquid medicine from the cloud grass bit by bit, but failed every time.

Zuo Feng originally thought that he had no way to extract the essence of the liquid medicine from the cloud grass, but he didn't expect that one day he would be able to face a cloud grass with such a huge difference in size.

Because Zuo Feng was too small and the cloud grass was too big, Zuo Feng easily destroyed the outer wall of the grass stem without hurting the inside. Then he broke the pale yellow pipe, and only the milky white liquid flowed out. They were the essence of the liquid medicine of the cloud grass.

Zuo Feng was not polite. He immediately lay on it and sucked it. Originally, four to five cloud grasses could barely extract a drop of liquid medicine essence, but now there was only one, and Zuo Feng almost drank it full.

The essence of the cloud grass liquid was swallowed by Zuo Feng. Before he had time to use his spiritual energy, the organs that came into contact with the liquid medicine began to slowly wriggle and repair themselves.

Although this repair process is far less than the energy released after killing the insects, it is already very fast.

If it were in the outside world, just in that breath, Zuo Feng almost drank the essence of the liquid medicine extracted from thirty or forty cloud grasses.

After a little slowing down, he puffed up his cheeks and sucked it hard. There was not much essence of the liquid medicine contained inside, but even if he took a sip like this, the amount sucked out would be almost the amount of seven or eight cloud grasses in the outside world.

This is not only an astonishing amount, at least Zuo Feng has never heard of anyone being able to directly obtain such fresh cloud grass liquid essence.

Ordinary medicine refining methods, as long as they are tempered in the medicine furnace or medicine cauldron, no matter how superb the skills are, both the amount of liquid medicine and the medicinal properties will be lost.

Even with the gentle mixing method, the medicinal properties will inevitably be lost because the refining time is slightly longer, but it is stronger than using flames.

As for the essence of the liquid medicine extracted by Zuo Feng, it was not processed in any way, and was directly inhaled from the cloud grass into the mouth, without any link in the middle to cause the medicinal properties to be lost.

Even though Zuo Feng has been studying alchemy for so long, this is the first time he has encountered such a well-preserved medicinal essence. This is also the first time he has directly absorbed a large amount of medicinal essence, and the effect also shocked him.

After the medicinal essence of Yuncao enters the body, it will gradually repair the internal organs, and then the medicinal properties will slowly spread, and the repaired area will gradually expand.

At the same time, although the slightly cold medicinal properties will bring some discomfort, the cold medicinal properties still have a good effect on pain relief.

When Zuo Feng closed his eyes and enjoyed it, a series of rustling sounds came from behind, pulling him back to reality. Zuo Feng almost forgot that he was still in danger, especially those insects were intent on swallowing him, and he couldn't stay here at all.

After looking back and confirming the number, distance and speed of the insects, Zuo Feng took a step forward. Zuo Feng frowned unconsciously after taking a step, but soon Zuo Feng's brows relaxed, because the pain at this time was much less than before.

As he took the second and third steps, he moved forward step by step. His speed was getting faster and faster, but he found that the pain in his body was rapidly weakening.

After a quick check of his body, Zuo Feng found that the essence of the medicine in the cloud grass was gradually spreading to his limbs.

The weaker he was, the faster he ran. The more the medicine spread, not only would the pain in his body be reduced, but the injuries in his body would also be repaired.

If it were someone else, he might run at full speed at this time to spread the medicine into his body as soon as possible. But Zuo Feng learned not only the method of refining medicine, but also the medical science from the Yao family.

He knew very well that for his current physical condition, if he ran at full speed, the medicine would spread quickly, but his body would soon be unable to bear it because it was too weak before and he was injured, and it might even be counterproductive.

Zuo Feng faced the pain that was being alleviated in his body and the injuries that were being repaired very calmly, and controlled his speed without haste. As he moved forward, he would specifically measure the distance between the insects behind him and himself, and how long it would take for him to be caught up at the current speed.

He could speed up, but he had to control his speed. This not only required a strong psychological quality, but also a great courage.

In addition, Zuo Feng did not forget to observe his surroundings while moving forward. He had tasted the "sweetness" of finding the cloud grass, so he was not only more attentive in his search, but also had a completely different perspective when observing.

In the past, when Zuo Feng was looking for medicinal herbs in the mountains, he would not miss any medicinal herbs that appeared in his field of vision. But now it is different. He observes from a completely "looking up" angle, and the medicinal herbs he is familiar with have become completely different.

However, after the experience of discovering the cloud grass, Zuo Feng has found a little trick. Now, during his escape, he also hopes to try whether the method of finding medicinal herbs is feasible.

Just after Zuo Feng walked forward for less than five breaths, a dry "weed" suddenly appeared in his field of vision. If it hadn't been carefully observed, it might have really been ignored as a weed. However, this time Zuo Feng observed more carefully and immediately noticed that this dry weed was actually a medicinal herb.

The reason why he noticed this weed was because Zuo Feng clearly saw that in the middle of the weed, there were some tumor-like protrusions. There were not many of them, and their distribution was irregular, but Zuo Feng was suddenly refreshed just because he saw them.

"Iron Heart Grass! It turns out that from my current perspective, it looks so ugly. I have never found it before."

It can be seen that Zuo Feng was in a good mood at this time, and he even joked while talking to himself. After seeing the Iron Heart Grass he mentioned, Zuo Feng changed direction without hesitation and rushed straight to the other party.

Although the cloud grass he saw before was the main material for refining the body-building powder, its effect on restoring oneself was still limited. And the Iron Heart Grass in front of him, although it was an auxiliary medicinal material, it was an indispensable part of refining the complex body powder.

Especially the medicinal properties of Iron Heart Grass, not only can it repair physical injuries, but also has a certain effect of restoring spiritual energy.

These two effects are exactly what Zuo Feng lacks the most at the moment. How can he not be excited after seeing them?

At this time, Zuo Feng no longer controlled his speed. He found that he had increased his speed by three times, but only felt a slight increase in pain. It can be seen that the Cloud Grass has fully exerted its effect.
