When all the employees of the medicinal herb base had eaten and left, Li Yong told Huzi to close the windows, then pull up all the curtains, lock the door, and then guard the door, not letting anyone in. Updates are fast and ad-free.

Next, Li Yong began the preparations before the alchemy. After thinking about it, he took out all the medicinal herbs at once, and put them in the pool to wash them one by one, because there were dust and pesticide residues on them, so they had to be washed.

In ancient times, there was very little dust, and there were no pesticides, and at that time they were all pure natural medicinal materials, which could be directly alchemized.

Nowadays, air pollution is serious, and various pesticides are sprayed to prevent insects and high yields. This invisibly affects the quality of the medicinal materials, and if it is not cleaned, the refined pill may not have any effect.

After all the herbs were carefully and carefully cleaned, Li Yong divided the herbs into different types and put them in four pots, either on low or high heat, or boiled or steamed, stewed or roasted.

Only longevity grass and longevity fruit were not treated.

Because the longevity grass and longevity fruit are his own planting, he has never sprinkled pesticides or chemical fertilizers, and the degree of contamination is less, and this is the main medicine, so there is no need to make preliminary preparations at all.

Next, Li Yong kept looking at the different medicinal materials in the four pots, carefully examining their changes, and corroborating them with the alchemy experience in the depths of his memory, and he found that the current pressure cooker also has the corresponding effect of the Dan furnace.

It's just that the effect is not too obvious, and some places can't meet the professional requirements of Dan furnace.

However, in the absence of the Dan furnace, Li Yong couldn't take care of it so much.

He could only find another way to find an alternative way of alchemy.

Otherwise, you can only watch the longevity grass wither and die, and watch the longevity fruit lose all its vitality.

It's a waste of course, so it's better to take a risk. If it succeeds, it is also a great reward.

Half an hour later, seeing that it was almost there, Li Yong turned off the fire.

At this time, although the kitchen was full of water vapor, there was no smell of medicine.

This first procedure only removes the dross from the herbs and does not produce a medicinal smell.

After waiting for about ten minutes, Li Yong lifted the lid of the pot, took out the water vapor in the first pot, took out the water boiled in the second pot, took out the oil from the third pot, and took out the medicinal juice stewed in the fourth pot. Then pour all of these into a pressure cooker, and finally add the longevity fruit and longevity grass, and start burning on a high fire.

This is the second procedure of Liandan, the essence is fused to generate medicinal power.

The rest of the pills, although they also had some medicinal power, were of little use in refining the Longevity Pill, and Li Yong was not prepared to refine other pills, so he had to pour them down the drain and discard them.

Not long after, with the stinging sound of the pressure cooker, the spacious kitchen gradually diffused with the smell of medicine, and as time went on, the smell of medicine became stronger and stronger.

Sniffing the fragrance of this medicine carefully, Li Yong faintly felt that this was very similar to the taste of the longevity pill in his memory, but there were still very slight differences, and he didn't know if it was because of the medicinal materials or because of the different refining utensils. Li Yong had no choice but to pray secretly, hoping that it would not affect the efficacy of the medicine.

He hurriedly opened his perspective eye, looked into the pressure cooker, and saw that more than a dozen medicinal essences had been fused, only the longevity fruit and longevity grass had not been completely fused. It seems to repel the heat of the essence of the herbs, and it is still intact.

It was a very strange situation, and it was never in his memory.

Is it because of this that there is a subtle difference in the taste of medicine?

Li Yong thought about it, but there was no good way to solve it, so he had to continue to increase the firepower, and he didn't believe that the stew would not be rotten.

After another thirty minutes, the longevity grass and longevity fruit finally changed, as the water in the pressure cooker became less and less, and the temperature became higher and higher, they finally split into many small pieces, and finally fused with the essence of the medicinal herbs. At this time, Li Yong suddenly realized that the pressure cooker was not as hot as the ancient Dan furnace.

Because the temperature is not enough, the longevity grass and longevity fruit are not stewed quickly.

This also affects the taste of the medicine, but I don't know if it will affect the effect of the pill.

Seeing that the medicinal juice had been successfully boiled, Li Yong turned off the fire and waited patiently.

At this time, the strong aroma of medicine in the kitchen, wafting out from the cracks in the doors and windows, Huzi took a few deep breaths, and felt refreshed, particularly energetic, and all full of vitality, which was a feeling of youth.

The medicinal fragrance continued to drift into the distance, and even Han Xifeng, who was walking in the medicine field, felt refreshed, as if he had taken a great tonic. He couldn't help but look into the kitchen and walked over.

Coming to a window, Han Xifeng found that the fragrance of the medicine was even stronger, he took a deep breath, and also had a feeling of youthfulness, which made him so excited that he almost jumped up like a child.

He craned his neck and looked inside, but saw nothing. Then, he came to the kitchen door and asked Huzi, "What are you standing here for?"

"Brother Yong asked me to stand here and not let people go in casually. Huzi replied truthfully.

"Oh, what is Xiao Yong doing in there? This smells so delicious!" Han Xifeng suddenly became interested: "Is he cooking dinner for us? This kid doesn't cook at home, how can he come here to cook?"

"I don't know. Huzi replied.

"Let me go in and have a look. Han Xifeng commanded.

"No, Brother Yong has an explanation, and no one can go in. Huzi stopped.

"I'm his grandfather. "Han Xifeng is still old.

"No one, including grandpa. Huzi said helplessly.

Han Xifeng had no choice but to give up, since Li Yong was not allowed to enter, he estimated that even if he went in, it might make Li Yong unhappy. However, he did not leave, because this special fragrance made him so comfortable that he seemed to be younger if he took one more breath. So he gathered around the kitchen door and waited.

Not long after, Han Dongtao and Sun Xiaomei also came, and they also wanted to go in.

This time, without Huzi stopping him, Han Xifeng had already said: "Even I can't get in, so don't think about it." ”

So, they waited outside together, waiting for the moment when Li Yong took the initiative to open the door.

Let's see what Li Yong is up to.

There were also some employees from the medicinal herb base who also came around, greedily breathing the medicinal fragrance in the air one by one.

In the kitchen, Li Yong waited until the pressure of the pressure cooker dissipated, then opened the lid of the pot and poured out the medicinal juice inside.

Half a pot of water boiled for more than two hours, and only a small half bowl remained.

Moreover, the color is still black and pasty, like a heavily polluted river, which looks extremely unclean. If it weren't for the refreshing medicinal fragrance that exudes from the heart, almost give it to others to drink, and no one else will drink it.

Moreover, the amount is still very small, if Li Yong is allowed to drink, he can drink it cleanly after drinking three sips at most, but among these three sips of medicinal essence, there are actually half of them impurities.

Modern pressure cookers, although the temperature is close to the height of torch alchemy, cannot automatically remove impurities like a professional Dan furnace, let alone automatically form a pill like a professional Dan furnace.

This is also a helpless choice, if there is a Dan furnace, who will replace it with a half-baked product like a pressure cooker?

Next, if you want to condense the essence of the liquid medicine into a pill, you need Li Yong to carry out the third procedure, manual slag removal, and the fourth procedure, manual condensation. Manually? That's right, manual.

Let's start with manual slag removal, which is a very old method, and there is almost no way to do it.

It is to stand there straight, pinch the eaves of the bowl with your fingers, and keep shaking back and forth at an even speed and in the same direction. The purpose is to let the impurities settle down and the essence liquid float.

For example, just like frying sesame oil, freshly fried sesame oil and sesame residue are mixed together. It should be placed in a large pot and shaken back and forth to allow the sesame residue to sink before the sesame oil can be removed.

Li Yong stood there and shook for more than half an hour, and finally sank the medicine residue.

Seeing that there was only a small sip of liquid essence left on it, Li Yong sighed and shook his head slightly.

I've been doing it for so long, and I'm so tired, I really don't know if I can condense it into a hand.

Gently put the bowl on the dining table, Li Yong used the small spoon that usually drinks soup, and the smallest spoon, to gently scoop out the essence of the medicinal liquid on it, one small spoonful after another. Fortunately, he has a pair of doctor's hands, and he has been practicing acupuncture for more than a year, and he has done meticulous work.

Now, it is also handy to do this kind of work of scooping out the essence of the medicinal liquid.

It didn't take long for him to scoop all the essence of the potion into another small bowl, which was only as much as a mouthful of water.

After the liquid essence and the impurities are separated, the impurities are black and have little value, but the essence of the liquid medicine is slightly yellowish in color, looking like thick old rice wine, which makes people have a great appetite.

After waiting for about ten minutes, and seeing that the essence of the liquid medicine gradually became cooler, like lard solidifying together, Li Yong started the fourth procedure, manual condensation. I saw him take out a small piece from the bowl and put it in the palm of his hand, like a ball of mud, and a yellow round pill was formed.

It also has his fine palm prints on it, which looks like a source pattern, full of mystery.

I pinched my fingers and looked at it for a moment, and it was only half the size of a fingernail. However, Li Yong shook his head and said to himself: "It's big." So, he split this pill in two and made it into two.

Originally, one pill could prolong life for about five years, but the effect of splitting into two was also reduced by half, and it could only extend life for more than two years.

Seeing that the pill in his hand was only the size of a soybean, Li Yong nodded with satisfaction.

Put the pill into the white medicine bottle that had been prepared a long time ago. Then, he took the remaining liquid essence that had been solidified into pills one by one, and finally obtained six pills.

"It's so little! It's been a long time since I got six grains. Li Yong sighed with emotion.

Then he comforted himself: "But if it were divided into two, it would be twelve." ”
