After Yun Feng finished refining the Beast Pill, he breathed for an hour. An hour later, Yun Feng said to Dan Lao, Dan Lao, I have already adjusted my breath, we can refine the Great Return Dan.

"Okay!"

Now, let's start refining the Great Returning Pill, you take out all the medicinal materials for refining the Great Returning Pill, and classify all the main medicines and the matching medicines. In this way, when practicing the elixir, you can grasp the degree of integration between the main medicine and the dispensing. In case there is any mistake between the main drug and the dispensing, we can also find out the key to the discord between the main drug and the dispensing in a hurry.

Dan Lao deserves to be an experienced pharmacist! At once, he clearly explained to Yun Feng the problems that would arise when practicing medicine.

I know what to do. After speaking, Yun Feng classified all the main medicines and dispensing of Da Huan Dan according to the meaning of Dan's old saying.

You first refine the fruit of the Yuan tree, in the refining is, the heat should not be too fierce, it must be refined with a simmer. In this way, the medicinal effect of the fruit will not be destroyed.

"Hmm!" I know, after Yun Feng finished speaking, he suppressed the blind true fire, refined it with the heat of the simmering fire, and returned the Yuan Tree Fruit.

A quarter of an hour passed, and the Huanyuan Tree Fruit in the Danding was reduced by half by Yunfeng. But inside the Danding, there appeared, a few drops of fragrant milky white medicinal juice. These few drops of medicinal juice are the result of Yunfeng's hour.

Half an hour later, there was a bang in the Danding, and the Huanyuan Tree Fruit in the Danding was thoroughly refined by Yunfeng into more than a dozen drops of milky white medicinal juice.

Then use a simmer to refine for a quarter of an hour, and completely refine the impurities in this medicinal juice, so that it can be left and the essence of the Yuanshu fruit juice can be returned. The pill looked at it, and the Returning Yuan Tree Fruit Dao in the Danding was completely refined by Yunfeng to extract the medicinal juice.

The clouds and the wind shone on Dan Lao's words, and the refined medicinal juice was refined with a simmer for another quarter of an hour.

Time passed minute by minute, and more than a dozen drops of milky white medicinal juice in Danding were refined by Yunfeng, with a trace of black medicinal residue. More than a dozen drops of milky white medicinal juice in Danding were also refined into the essence of ten drops of medicinal juice again.

Looking at it, there are ten drops in Danding, bursts of fragrance, milky white Huanyuan tree fruit, refining and melting into a medicinal juice. Yun Feng took out one, made of warm jade, and filled the ten drops of medicinal juice in the Danding into it. Then, Yunfeng refined it again, and combined it with the fourteen kinds of dispensing of the Yuan Tree Fruit.

Three hours later, Yun Feng refined all the fourteen kinds of medicines into the essence of the medicinal juice drop by drop.

At this time, Yun Feng integrated the medicinal juice of ten drops of the Yuan Tree Fruit and the medicinal juice of the fourteen kinds of medicine that had been refined before into the Danding and refined them together.

Half an hour later, all the medicinal juices in Danding had been refined into a viscous medicinal liquid.

Yun Feng put this liquid medicine into a jade bottle. Immediately afterwards, he took out a fiery red juyang fruit and put it into the danding to continue refining.

This Juyang Fruit should be refined with martial fire, the more fierce the fire, the better, the fire is smaller, it will make changes in the body of Juyang Fruit, so that it cannot meet the requirements of you to refine. Dan Lao watched, Yun Feng took out the Juyang Fruit and put it in the Danding to refine it.

Hearing what Dan Lao said, Yun Feng increased, and blindly entered the real fire inside Danding.

The Juyang Fruit in the Danding was red and red by the real fire of Yunfeng, just like an iron ball that was burned by the fire in the training furnace. Anytime, anywhere, it is possible to be melted into iron by the fire in the furnace.

A quarter of an hour later, the Juyang Fruit in Danding had already turned into more than a dozen drops, blood-red and blood-red medicinal juice, and Yun Feng put the medicinal juice of Juyang Fruit in Danding into a jade bottle. He went on to refine the fourteen kinds of medicines of Juyang Fruit.

A drop of the essence of the medicinal juice, enjoying it in Danding, Yunfeng blindly burned with real fire, Yunfeng saw the residue in the medicinal juice, and almost eliminated it, he took out the medicinal juice of Juyang Fruit and entered it into Danding. Suddenly, the fourteen kinds of dispensed medicinal juices in the Danding were scattered like a little ghost seeing the king of Hades, and they seemed to scatter one by one.

"Hmph," I don't want to fuse, it's not that easy, you all give me to obediently roll back and fuse with the medicinal juice of Juyang Fruit." Yun Feng looked at the fourteen kinds of medicinal juices in the Danding, after he injected the medicinal juice of the Juyang Fruit, the fourteen kinds of medicinal juices in the Danding, drop by drop, all hid around the Danding, refusing to fuse with the medicinal juice of the Juyang Fruit. Yun Feng immediately changed his alchemy technique and shrouded towards the medicinal juice in the Danding.

The fourteen kinds of medicinal juices in Danding were obediently fused with the medicinal juices of the Juyang Fruit in the technique of cloud and wind transformation.

Yun Feng saw that all the medicinal juices were fused together, and immediately, he increased the firepower of the True Fire and refined them into a viscous liquid medicine.

"Whew," Yun Feng took a deep breath, then took out a cyan green grass and put it into the Danding to refine.

Green to grass, to use soft fire to refine, it can't be used, martial fire and simmer to refine, martial fire is too fierce, will return green to grass, directly burned into ashes, simmering is not soft, will return green to grass, the medicinal juice in it directly evaporated. It is best to refine the heat of green and grass, only the soft fire that is five points weaker than the simmer, and the refining is the best. Dan Lao, who was standing on the side, saw that Yun Feng took out the green grass and put it into the Danding refining Dao.

Yun Feng listened, and Dan Lao, who was standing on the side, explained to himself how to refine the green grass with the right heat. Immediately, he weakened the blind true fire into a wisp of flame that seemed to be blown out by the wind at any time, wrapping the green grass in the Danding.

"Well, what a natural pharmacist!" Dan Lao saw that the cloud wind was a little penetrating.

After refining the medicinal juice of the green returning grass, Yun Feng followed and refined the dispensing of fourteen kinds of green returning grass.

Da Huandan, 90 kinds of medicinal materials are refined, there are six main medicines, 84 flavors of dispensing, each of the main drugs, accompanied by 14 flavors of dispensing. The medicinal juice of each fourteen kinds of dispensing must be fused with the medicinal juice of the main medicine before it can be carried out, and in the last step, the six main medicines are melted and condensed to make a pill.

After refining the medicinal juice of green returning grass with soft fire, the dispensing medicinal juice of fourteen kinds of green returning grass also fused together with the medicinal juice of green returning grass, and was refined into a ball of green viscous liquid by Yunfeng with a simmer.

The white jade Zeng Yuan branch is refined by fierce fire, because it is hard itself, and only fierce fire can melt the hardness of its branches.

"Huh," Yun Feng suddenly increased, blindly the power of the true fire, refining the white jade Zeng Yuan Branch, the flame in the Danding, was suddenly increased by the cloud wind, and the real fire was suddenly increased, and suddenly, towards the eight dragon and phoenix pills of the Danding, one after another flames.

The white jade Zeng Yuanzhi in the Danding turned into drops of milky white and thick essence under the fierce attack of the cloud wind. And the dispensing of the fourteen white jade Zeng Yuanzhi was also thrown into the Dan furnace by the cloud wind at this time, refined into a drop of the essence of the herb and the white jade Zeng Yuanzhi, together in the Dan furnace, refined into a thick herb essence.

The nine-colored green fruit is simmered and refined, because it contains nine different medicinal ingredients in the body. Therefore, it is necessary to use a simmer to refine the medicinal juice in the fruit into an ingredient. Dan Lao explained.

In the Dan furnace, Yunfeng used a ball of simmering fire to refine the nine-colored green fruits. Dan Lao said that he was right, there are nine different medicinal ingredients in the body of the nine-colored green fruit. Therefore, Yunfeng used a simmer to refine the nine different medicinal properties in its fruit body into a medicinal property, and only in this way can the refined medicinal juice be considered qualified.

After three hours of simmering refining by Yunfeng, there were nine different medicinal properties in the nine-colored green fruit. Already, it has been refined by Yunfeng into a drop of medicinal liquid the size of a quail egg.

Yun Feng put it away, this drop of quail egg-like liquid, and he began to refine, the fourteen kinds of dispensing of the nine-colored green fruit.

"Bang," came the explosion of herbs turning to ashes from inside the Danding. It may be that Yun Feng's heart was too anxious, and the heat was not well controlled, so it led to the failure of the herb refining.

The heat is not well controlled, and the fire is a little fierce, which may be the reason why you consume too much true qi. You'd better take a rest first! When the pranayama is ready, we will continue to practice the Great Returning Dan, and Dan Lao will face Yun Fengdao.

I'll do my breath first, and when I'm done, I'll come and refine the potions," Yun Feng replied.

Yun Feng sat cross-legged, and immediately, closed his eyes and began to breathe, his own true qi, maybe it was, he consumed too much of his own true qi in order to refine the pill. Yun Feng's cross-legged pranayama has been in place for half an hour.

"Whew," half an hour later, Yunfeng recovered, and his spirits were high.

Dan Lao, how long have I been pranayama?After opening his eyes, Yun Feng asked Dan Lao.

Hehe, not much, half an hour, Dan Lao replied with a smile.

Okay, let's go ahead and refine the herbs. After speaking, Yun Feng took out another piece of grass and began to refine. This time, Yunfeng's refining went very smoothly, and there were no signs of deviation in the heat, and the fourteen medicinal herbs were quickly refined drop by drop.

Yun Feng looked at it, and the medicinal juice in the Danding quickly took out, and the medicinal juice of the nine-colored green fruit was fused into the Danding and the medicinal juice of the fourteen kinds of nine-colored green fruits.

Millennial purple Lingzhi, simmering and refining, Dan Lao watched, Yunfeng took out the purple Lingzhi and said.

After Yun Feng threw the purple lingzhi into Danding, in less than half an hour, he refined more than a dozen drops of purple viscous purple liquid, and put these liquids into the jade bottle. Yun Feng continued to refine, dispensing the medicinal juice, dispensing the medicinal juice drop by drop. And these, the medicinal juice of the dispensing was quickly fused together with the medicinal juice of the purple lingzhi and refined into a viscous medicinal liquid.

Okay, now, you can put all the medicinal liquids into the Danding, and use the fierce fire to fuse them together and refine them into a great return pill, and the Dan Lao looked at the refined medicinal liquid channel.

"Well, Yun Feng nodded in response. Immediately, he integrated all the previous five medicinal liquids into it, and used fierce fire to refine and fuse them together to refine them into the Great Returning Pill.

A day and a night passed, and in the dragon and phoenix eight mouths of the Danding, there was a burst of the fragrance of the pill.

Yun Feng stood in front of the Danding, looking at the inside of the Danding, the oval half-grade pill of the Great Returning Pill that was about to be successfully refined, Dan Lao, this Great Returning Pill should be able to be baked after another day of warmth, right?

That's right! After a day of simmering, Da Huan Dan was successfully refined.

The time of the day passed quietly, and the big return Dan in the Danding had ushered in the moment of its birth.

"Boom,"

At this moment, suddenly, there was a terrifying thunderclap in the sky.

Not a good boy, this big pill is already a seventh-grade low-grade pill. Now, it is about to accept the baptism of the Dan Tribulation, if one is not good, this big Dan will be destroyed by the Dan Tribulation, Dan Lao heard the thunder in the sky, and said to the cloud wind.

(Crazy for recommendations, everyone give more!)
