Time passed quickly, and three days passed.

In the past three days, Mu Yiyang almost never slept or ate to read through the medicine books, and finally wrote down the medicinal veins and veins of more than a dozen elixirs that he was familiar with, which could be regarded as a small gain.

And under Mu Tianfu's careful conditioning, his soul power damage also recovered quickly, basically no longer having a headache, and he was barely able to use his soul power for imperial training.

Mu Tianfu would occasionally enter the room to guide him in his studies, but more time was in the Dan room, looking at his haggard appearance, Mu Yiyang probably guessed that he was refining a furnace of high-grade pills, as for what he was refining, he didn't know.

"According to what Fu Bo said, the cultivation of the Tongmai technique is important to practice, rather than blindly memorizing, since the soul power has almost recovered, it is better to cultivate a few low-level elixirs and give it a try. ”

In the room, after reading the medicine book for a night, looking at the sky that had just lit up slightly outside the window, Mu Yiyang let out a sigh of relief, said softly with a tired look, and then got up from the bed and walked to the courtyard outside.

After a while, Mu Yiyang came to the courtyard, stopped in a corner on the far left, and slowly leaned down after some observation.

"The fertility of this land is not bad, but the content of yin and yang qi is a little lower, so it seems that you have to prepare some spiritual liquid. Grabbing a handful of dirt on the ground and sniffing it in front of his nose, Mu Yiyang said with a slight frown.

According to the "Basic Chapters of the Pulse Technique", just like the spirit stones that contain a large amount of yin and yang, the soil also contains yin and yang qi. It's just that compared to the spirit stone, most of the soil has too little yin and yang energy, and it can only be used to breed some ordinary trees, flowers and plants and some low-level elixir seeds, so it is not very useful.

However, there is also a small amount of soil that contains extremely high yin and yang qi, which can be used to cultivate some high-level elixirs, which are very popular with some pharmacists, and such soil is called spiritual land.

Because of some special reasons, spiritual land is born with a special smell, generally speaking, it can be classified into four types, which represent the level of its yin and yang qi content.

The first is an unpleasant earthy smell, which means that the yin and yang qi of the spiritual soil is scarce, and can only be used to cultivate some low-level elixirs.

The second is the pungent smell of plants and trees, which means that the yin and yang qi content of the spiritual soil is medium, which can basically meet the needs of the growth of ordinary elixirs.

The third is a good smell of flowers, compared with the previous two, the yin and yang qi has a qualitative difference, and it has an amplifying effect on the improvement of the medicinal properties of the elixir, and the effect is extremely high, which is the best spiritual land.

As for the last one, it is a faint fragrance, and the content of its yin and yang qi is so high that even the spirit crystal that is one level higher than the yin and yang power content of the spirit stone is difficult to reach, which can not only accelerate the growth rate of the elixir, but also continuously improve the physiological structure of the elixir, helping it break through the shackles and upgrade to a higher-level elixir, which is very rare, and it is the best spiritual land.

Although the soil in Mu Yiyang's hand had an unpleasant earthy smell, it was not very strong, so if he wanted to better cultivate the elixir seeds, speed up their germination, and use them for the practice of the Pulse Technique, he needed to adjust the Yin and Yang Qi content of the spiritual soil through the spiritual liquid.

The so-called spiritual liquid is the medicinal power of five different attributes of elixirs of alloy, wood, water, fire and earth, and reverses the power of the five elements with the way of mutual restraint of the five elements, transforming it into yin and yang qi, and injecting it into clear water to form a special liquid that can be absorbed by the spiritual soil and increase its yin and yang qi content.

Mu Yiyang is no stranger to the spirit liquid, as early as a few years ago, he saw Mu Tianfu concoct it with his own eyes, but his soul power control ability has never reached the early stage of the god control realm, and he has never tried it, and now he finally has the opportunity to try it, and immediately used a few small basins to fill the courtyard with some soil, and took a sufficient amount of elixir according to the recipe in the book, and returned to the room and started the first preparation.

"Golden light vine, green rock wood, water spirit bamboo, fire cloud fruit, earth crystal lotus. The prepared first-order low-level elixir with five different attributes for preparing the low-grade spiritual liquid was placed on the table in the room, and Mu Yiyang said with words in his mouth.

"According to the book, in order to prepare the spirit liquid, you first need to extract the essence of the five elixirs, and I have learned fire control before, so this step is not difficult for me. ”

Picking up a golden light vine more than two inches long from the table, Mu Yiyang carefully folded it in half at the section, and put it into the small porcelain bowl filled with clear water that had already been prepared, but he was not in a hurry to extract the medicinal liquid, but took out the other four small stoves, and put the remaining four elixirs into the small bowl.

"If I had done it before, controlling three small stoves at the same time would have been my limit, but now I am not the same person I used to be. ”

Meng Yi used the power of the fire attribute bloodline in his body to ignite the five small stoves, Mu Yiyang said with a little emotion, and then urged the soul power to increase the intensity of the flames, and the clear water in the five small bowls quickly boiled, and a special smell of herbs mixed with the smell of various elixirs suddenly spread from the room.

"Only through the continuous high temperature can the elixir essence be completely forced out, this step seems simple, but in fact, the loss of soul power is extremely great, no wonder Fu Bo asked me to practice the art of fire control and imperial objects first, if there is no previous accumulation, even if my soul power talent is higher than ordinary people, it is still far away to prepare this spiritual liquid. ”

With the continuous infusion of soul power, the temperature in the furnace continued to rise, the water in the bowl gushed more violently, and a large amount of water then evaporated into the air, forming water vapor, and a drop of golden liquid finally appeared in the small bowl with golden light vines after half a pillar of incense, and four other small liquids of different colors also appeared in the other four furnaces.

"Condensation into liquid, this is a sign of the outflow of elixir essence. ”

Looking at the five drops of small liquid coming out of the small stove, Mu Yiyang was overjoyed, and then poured the hot water that had already been prepared into the five small porcelain bowls, urging the soul power again, and the flames in the furnace suddenly rose, and more drop-like small liquids came out of the five small bowls.

After about a pillar of incense in this way, when Mu Yiyang was sweating profusely, the five elixirs in the bowl no longer had spiritual liquid coming out, but each gathered into a ball, clearly separated from the clear water in the bowl.

"It seems that it is time to extract the elixir essence. ”

Because the essence of the elixir is the original power inside the elixir, it has a natural rejection of external things, so it cannot be directly dissolved with water, and the water needs to be evaporated to extract the pure medicinal liquid.

Therefore, seeing that the essence of the elixir condensed into a ball, Mu Yiyang's expression did not change, but urged the soul power vortex, separated another soul power, and tightly wrapped the five balls of medicinal liquid to prevent it from losing its medicinal power in the process of water evaporation.

Afterwards, Mu Yiyang picked out the elixir residue again, urged the flame with all his strength, and used the high temperature to evaporate the clear water in the bowl, leaving only five clusters of shining elixir essence to stay in the bowl.

"The next step is to merge ......"

Filling the liquid medicine in the five small bowls in small bottles, Mu Yiyang took a deep breath, took out another clean large porcelain bowl, poured out a drop of liquid medicine from the five small porcelain bottles, and began the final step of preparing the spiritual liquid.

"The power of the five elements is mutually reinforcing, although there are rules to follow, but the fusion of the medicinal liquid actually considers the ability to control the soul power. Directly fusing the five groups of medicinal liquid, the repulsion of the medicinal power is too strong, and I can't do it with my current ability to control the soul power, but if I fuse it drop by drop, although it is a little slower, it is the most suitable method for me. ”

Looking at the five drops of medicinal liquid in the porcelain bowl that were mutually exclusive and did not fuse, and the color and medicinal power were different, Mu Yiyang said thoughtfully, and then urged the soul power, driving them to start the first fusion.

Under the wrapping of soul power, the five drops of medicinal liquid slowly condensed together, although there was still a certain degree of rejection between each other, but with the increase of Mu Yiyang's soul power intensity, this resistance gradually weakened, and the five drops of medicinal liquid also showed signs of fusion.

"It's working!" Seeing this, Mu Yiyang was overjoyed, although his method was a bit stupid, but now it didn't seem to be useless.

Thinking so, Mu Yiyang wanted to strengthen his soul power and increase the speed of the fusion of the medicinal liquid, but at this moment, a bright light suddenly came out of the porcelain bowl, and immediately followed, he saw that the five drops of elixir essence that had been condensed together before were somehow separated, returning to the previous state of being distant and mutually exclusive.

"How can this be?" Seeing the five drops of the liquid medicine suddenly separate, Mu Yiyang frowned tightly, a little surprised.

"Is it because I injected too little soul power?" After thinking for a while, Mu Yiyang muttered to himself, and then increased the strength of his soul power, and began the second fusion, but it was also about to succeed when it changed and the fusion failed.

"Could it be that the amount is too small, causing the reaction of the power of the five elements to not be violent enough?"

After trying a few more times, Mu Yiyang suddenly had some doubts about his method, so he added more medicinal liquid to the porcelain bowl, but was disappointed to find that with the increase in the amount of medicinal liquid, the repulsion of the elixir essence was almost multiplied, and there was no way to condense them together.

"Since it's not a matter of quantity, it means that my previous thinking should be right, so what's the problem?"
