Du Xu stretched out his hand to summon four skeleton demons, all of which were humanoid white bone puppets, which were trophies for killing the black-robed evil cultivators, so that Du Xu could refine it again, and his ability was greatly increased, his arms had the strength of a thousand catties, and he was hard-working.

Although these qualified coolies are very poor in appearance and their spiritual intelligence is not high, they are more than enough for the fire boys to be used for alchemy. But Du Xu was not satisfied with this, it would be great if he could train some monsters to be boy waiters, but now he can only use them first.

Du Xu ordered one skeleton demon to add carbon to the medicine furnace, and the other went to the pharmacy to bring a large plate of herbs that needed to be used.

Du Xu is going to refine a few powders today to nourish the body and promote physical exercise. But he was actually refining medicine for the first time, although there were many records of pills in the Taoist scriptures, but after all, his hands were born, so he was ready to refine an ordinary pill with relatively low difficulty first, and practice his hands. Otherwise, he would have eaten enough to support him, and he would have to refine the pill for Li San! A monk like Du Xu, whose heart is empty except for cultivation, can spend countless hours on cultivation, but he is stingy with a little time spent on things that have nothing to do with cultivation or even hinder it.

Li San's subordinates are only used by Du Xu to collect cultivation resources at this stage, and with Du Xu's current progress, there will be no use for him in five years, so Du Xu will not spend his precious time on him.

Du Xu looked at the "Holy Hand Chapter" left by the poisonous hand scholar, and picked out some medicinal materials: Shengbanxia, Shengnanxing, Qingpi, Qianghuo, Sichuan Pepper, Chuanxiong, Elephant Skin, **, Deer Antlers, Wujia Skin, Comfrey, Big Aconite, Wasp's Nest, Tiger Claw Pair, Eagle Claw Pair, There are actually green salt, old vinegar, these things, it seems that Li San is really ready.

His soul is strong, and close to the avenue, human senses perceive only one ten-thousandth of the cosmic information, with the practice can gradually feel many ordinary human beings can not feel things, the Buddha said that people have nine senses, ordinary people only have five senses and five senses are more clear, the sixth sense belongs to the scope of the practitioner's perception, but Du Xu's soul belongs to the innate gods, and the perception of cosmic information is a hundred times stronger than that of humans.

Now Du Xu looked at the antidote of the eagle claw hand on the "Holy Hand Divine Chapter", and his soul instantly deduced the various medicinal properties of the drugs on the prescription, and the effects after the combination and matching, and those that can be replaced and strengthened the therapeutic effect.

However, after a while, Du Xu deduced the pill that was a hundred times stronger than the medicinal wine on the "Holy Hand God Chapter", and he grabbed a handful of Banxia from his side, and he didn't need to weigh it to know that Banxia's medicinal properties were exactly the same, these medicinal materials were grass root bark in the eyes of humans, but in Du Xu's eyes, they were a combination of medicinal properties with different attributes.

Du Xu finished selecting the medicinal materials after dividing five by two, the skeleton demon next to him had already warmed the fire, Du Xu wrapped the medicinal materials with true qi, and threw all the medicinal materials into it. The order of the drug is very important, you can't make any mistakes, otherwise the poison won't kill you!

But Du Xu is different from these people, the old pharmacist has to use the furnace fire to induce specific medicinal properties, and carefully combine the medicinal properties in the order of the prescription to practice a drug with unique effects. But Du Xu's method is very simple, using true qi to catalyze the medicinal properties of specific medicinal materials, and using true qi to promote the fusion of medicinal properties.

That's right, it's so simple and crude, who told him that he can accurately perceive the changes and existence of medicinal properties?

Du Xu put the medicinal materials out of the furnace, and under the incineration of the furnace fire, a high-frequency molecular vibration shattered the medicinal materials, and under the control of the true qi, some of the medicinal materials were changed, and the medicinal ingredients that were accurate to the atomic level were changed, leaving the medicinal ingredients that Du Xu needed, and the other medicinal ingredients were turned into ashes under the furnace fire and discharged from the Dan furnace.

The medicinal properties of dozens of medicinal materials, under the control of Du Xu's powerful soul power and the precise control of true qi, reacted in order, catalyzing a unique heaven and earth spirituality, Du Xu divided them into five parts according to the best proportion, each part was condensed into a pill, and under Du Xu's control, he jumped out of the Dan furnace and jumped into a small jade bottle.

The whole process is simple and rude, and there is no unique beauty that belongs to alchemy at all, and it is purely relying on the spirit to bully mortals.

Du Xu covered the stopper of the jade bottle, and picked out ginseng, Poria cocos, Shou Wu, Huang Jing and other medicinal materials rich in essence from the side, the only medicinal properties needed for these medicinal materials are strong essence, Du Xu is now refining this furnace "Essence and Blood Prosperity Great Dan" was originally to use the essence and blood of a century-old beast as the main medicine, and use ginseng and other drugs to draw out the essence of essence and blood, waste nine percent of the essence, and practice into a "Essence and Blood Prosperity Great Dan" that can be gently absorbed.

But this is the practice of ordinary pharmacists, Du Xu is going to directly use the zombie's corpse pill to refine this elixir, use the fire's medicinal herb essence to neutralize the yin poison gas of the corpse pill, and refine the zombie essence into something that can be absorbed, and the effect is far better than the original pill.

Of course, there are still side effects, the zombie's corpse poison Du Xu did not fully unravel, leaving a part of the internal force of the person taking the pill with the characteristics of corpse poison, and the power is greatly increased.

Du Xu felt that Li San would definitely like this side effect more!

There was nothing difficult about this furnace of elixir, and it was soon baked. A total of thirty-six pieces of "Essence and Blood Vigorous Qi Great Dan", thousands of antidotes for side medicines, this furnace pill is a hundred times stronger than the original medicinal properties, one is enough for a master to digest for a year, of course, the medicinal properties will be latent in the body, let them digest slowly.

After the practice of the works, the rest is the decoction that Du Xu wants to use himself, and the only use of this decoction is to provide the special medicinal properties required by the human body for the development and growth of the human body.

Even monks like Du Xu still need to eat and supplement the nutrition for exercising at the stage of forging the foundation of the Dao, and at this time, the monks' demand for nutrition has reached a terrifying level, and some even eat the same thing every day, not because they lack protein and fat, but because they lack some special substances for the needs of the human body.

The "Renyuan Great Dan" that Du Xu wants to refine is the elixir that provides these medicinal powers, the medicinal power is very complex, and it is definitely highly toxic to ordinary people, but if you don't practice well, it is normal to poison cultivators. Although Du Xu doesn't have to worry about being poisoned by the pill, he can sense the medicinal properties! But unlike the pills refined before, the "Renyuan Great Dan" is a series reaction of more than a dozen medicinal properties, and after swallowing, the last step in the human body is completed to become a pill.

Du Xu's true qi holds a century-old seven-leaf ginseng, carefully infiltrating the ginseng with true qi, in Du Xu's perception, the medicinal properties of the ginseng slowly change under the baking of the furnace fire, Du Xu carefully controls the temperature of the furnace fire, and keeps it at a very precise level.

Soon, the medicinal properties of ginseng changed to the point that they met the requirements, Du Xu decisively changed the method, quenched the medicinal properties into a liquid medicine, preserved them with true warmth, and then put the medicinal materials into the furnace one by one to quench the medicinal liquid. In the medicine furnace, more than a dozen masses of liquid medicine of different colors and sizes were suspended in the furnace.

Under Du Xu's control, they were fused into a ball in order, and under the catalysis of true qi, the medicinal properties occurred, Du Xu cheered up, accurately controlled the process, and at some critical times, played a trick to collect the spirituality between heaven and earth, and put it into the medicinal liquid.

Soon there was only a ball of liquid medicine suspended in the fire, Du Xu's spirit was shocked, and in his senses, the medicinal properties of the liquid medicine were flashing rapidly, and he had to quickly enter the pill in the middle of the change in the medicinal properties of the liquid medicine to guide the changes in the medicinal properties.

The last mass of liquid condensed into gold and slowly swirled. At this point, even if the Ren Yuan Da Dan has been practiced, all that remains is to urge the furnace fire, warm and nourish the medicinal liquid, let it collect the vitality and spiritual faith between heaven and earth, and finally crack the pill to take shape.

Du Xu finally breathed a sigh of relief and waited for the pill to take shape.

Time passed in a flash, a few hours passed like this, Du Xu meditated in the Dan room, a faint fragrance that seemed to be floating in the air, Du Xu smelled the fragrance, felt that his mind was clouded, and he was about to fall asleep.

He hurriedly used his true qi to dispel the aroma before he eased up. He sank his spirit into the furnace and saw a mass of liquid medicine slowly splitting, divided into dozens of parts, and from time to time the liquid split there was residue of medicine, which fell into the furnace fire and turned into a poisonous incense. Du Xu was afraid for a while, and carefully collected dozens of condensed pills, and also collected two large bottles of medicine residue.

Du Xu looked at the more than ninety pills and found that it was enough for him to use for three months, so he happily put away the pills and walked out of the fire room.

Outside the fire room, Li San was already waiting, Du Xu casually handed him the elixir for hand practice, instructed a few words, returned to the warehouse and used the Kunlun mirror to put away the plants of medicinal materials and some concocted medicinal materials, and turned around and left the Li Mansion.
