Just as Ye San thought.

The rarer the herbs, the more difficult it is, and the more mysterious the prescriptions, the lower the probability of successful brewing.

In ancient times, many people believed that this was because the efficacy of those prescriptions was too mysterious, too rebellious, and contrary to the laws of birth, aging, sickness and death in the way of heaven, so they were jealous of heaven, and God would not allow it to succeed too easily.

Ye Xiu often saw these descriptions when he looked through various legends of Chinese medicine, and even in some orthodox classics of Chinese medicine, he could see similar descriptions.

But Ye Xiu knew very well that this statement was just caused by the lack of deep understanding of the medicinal properties of some pharmacists and ordinary people in ancient times.

The so-called heavenly jealousy, in fact, is just because of the mysterious prescription, its boiling method, more subtle, for all kinds of details are relatively high, the more mysterious the medicinal materials, the more the slightest mistake can not be made.

The slightest mistake in the details can lead to the failure of the entire boiling process, which is the so-called phenomenon of natural jealousy.

It was precisely because he knew this truth that Ye Xiu did not dare to be careless about the boiling process, and before he really started it, he chose to calm down and concentrate his breath first, so that he was at the peak of his body and mind before starting to do it.

After doing it, Ye Xiu didn't dare to relax in the slightest.

In fact, he won't be slacking off.

Because Ye Xiu quickly devoted himself to the process of boiling.

For Ye Xiu, this is the first time that he has the opportunity to practice this prescription, and he has the opportunity to boil the life-sustaining pill, and Ye Xiu also knows how much these medicinal materials for the life-sustaining pill are so desperate, the Ye family has done their best, and they have only collected these two copies, and maybe even the only two copies in the world, and there is no room for the slightest mistake.

Once you make a mistake, the loss will be enormous.

In addition to cherishing these medicinal materials, Ye Xiu also cherished such a rare opportunity to practice.

Therefore, Ye Xiu was extremely focused from the beginning, and Ye Xiu had a characteristic that when he really focused on one thing, it was easy to devote himself to it.

This is a great advantage of Ye Xiu, and it is also an important reason why his learning efficiency and work efficiency can far surpass ordinary people.

When Ye Xiu devoted himself to one thing, he was truly selfless.

All he sees is what he is invested in, and everything else is automatically cut off by him, including the passage of time.

In the past, he was like this when he devoted himself to cultivation, when he was reading books in the library of the University of Chinese Medicine, and now he is also like this when he is engaged in the process of boiling medicine.

For two days in a row, Ye Xiu was completely immersed in the process of boiling the life-sustaining pill.

In the past two days, Ye Xiu has not left the kitchen for a single step, has not taken a sip of water, has not eaten a mouthful, and has not rested for even a minute.

Although for Ye Xiu, under normal circumstances, such a short period of two days without eating or drinking is not a problem at all, but these two days are not an ordinary situation, in these two days, Ye Xiu's energy and physical strength have been continuously and hugely consumed, and even this consumption is no less than the battle with Old Man Fang when he was in the southwest, the only difference is that he did not have the pressure of life and death when he faced Old Man Fang.

When Ye Xiu was investing, when he was boiling, he didn't feel tired at all, because he had already put himself into a state of complete forgetfulness, but when he finally completed the last key step and completed the boiling process, his whole person was directly paralyzed on the ground.

Unexpectedly, the process of boiling the life-sustaining pill was so hard!

Sitting on the ground, Ye Xiu's eyes looked at the small medicine stove in front of him, feeling the irrepressible feeling of exhaustion in his body, and he couldn't help but have a wry smile in his heart.

However, in just a moment, the moment Ye Xiu smelled the faint medicinal fragrance overflowing in the air, the wry smile on Ye Xiu's face disappeared, and it was replaced by a happy and relieved look, even a look of satisfaction and pride.

Fortunately, it finally succeeded!

As long as the medicine refining is successful, all this effort is worth it! It is even earned, because in addition to boiling into a life-sustaining pill, in the process of boiling this time, Ye Xiu also earned the experience of boiling!

This experience is invaluable!

....................................

Five o'clock in the morning.

A moment of whiteness of the fish's belly was revealed in the sky.

Ye Xiu opened his eyes.

The moment he opened his eyes, a glittering light flashed in Ye Xiu's eyes, and this light was a little more powerful than before, and it was closer to turning into substance.

If it was an ordinary ordinary person, or even an ordinary martial arts that was not congenital, I was afraid that under Ye Xiu's eyes, he would be so frightened that he knelt down.

Even if you are an innate master, you may not be able to withstand this compelling light.

Cultivation has improved again!

This time, the process of boiling medicine is really a big profit!

Those medicinal fragrances, as well as those medicinal residues, really have a very great function!

After seriously experiencing the power in his body, Ye Xiu's eyes showed a look of uncontrollable excitement.

Last night, after completely completing the process of boiling the medicine, truly boiling the life-sustaining pill, and putting it away, Ye Xiu started pranayama cultivation directly in the kitchen.

Before cultivating, Ye Xiu directly swallowed the medicinal residues left over from the process of boiling life-sustaining pills, and he had a faint feeling in his heart that these medicinal residues might have a certain effect.

Although these are all medicinal residues, the essence of the real medicinal materials, they have all been boiled into the life-sustaining pill by him, but Ye Xiu feels that after all, these medicinal materials are all extremely rare medicinal materials, even if they are medicinal residues, they will definitely not be completely useless, and although the boiling process is already very strong, and all the medicinal power has been narrowed as much as possible, it is still impossible to really narrow all the medicinal power.

So Ye Xiu swallowed all these dregs.

Moreover, Ye Xiu didn't want to waste the medicinal fragrance in the air, so he simply cultivated directly in the kitchen, and even in order not to waste the medicinal fragrance in the air as much as possible, Ye Xiu didn't bother to deal with the filth after boiling the medicine for two days.

Facts have proved that Ye Xiu's idea is correct.

The effect of last night's cultivation far exceeded the usual cultivation, and it was even directly equivalent to a month's cultivation effect.

The skill of his body, which had not felt a significant increase in his body for many days, had obviously increased by a small margin! Although it was only a small section, Ye Xiu knew that this was already a very difficult task, you must know that he was already in the middle stage of the innate stage, and one step further would be the late stage of the innate stage!

Now, every bit of refinement in Ye Xiu's skill is equivalent to getting a little closer to the late innate stage!
