Poor villages in the rebirth era, take the whole village to eat meat

The refining of Huangyun Dan is much more difficult than Ningshen Pill. Ningshen Pill is just an ordinary pill that has not been prepared, basically anyone who is an alchemist can refine it.

Huang Yundan is different, his target audience is the Nascent Soul Stage, even the top-quality Huang Yundan, Huashen can use it.

Therefore, it can be said that it is one of the more popular ones among the first-grade pills.

The most important thing is that his ingredients are relatively easy to find, most of which are common herbs, and the main one is a herb called Huangyuncao. This kind of Huangyuncao is relatively easy to cultivate, so the price is not very high.

The most difficult thing is that dozens of herbal medicines that grow and restrain each other are used here, and if you are not careful, you can go directly to the west.

When Su Han got the elixir, he first spent a long time researching each herbal medicine clearly, and carefully and repeatedly studied their habit of mutual generation and mutual restraint.

At first, it was refined according to the formula of Huang Yun Dan, but as expected, just after putting in the third medicinal material, it exploded immediately.

Among them, the main yellow cloud grass is compatible with most of the medicinal materials, so we must pay special attention to any slight changes in it during refining.

The little light ball at the side finally calmed down, seeing Su Han's frowning expression, the frustration in his heart finally eased a little bit.

"The refining of Huang Yun Dan is far less simple than the Concentration Pill. There are so many things to pay attention to. It is completely impossible to change the formula of the pill as you did before."

The little ball of light would not give him any hints during the inheritance assessment. In a sense, it could only be regarded as a guide.

Su Han carefully observed these medicinal materials, and put together all the medicinal materials that generate and inhibit each other, thinking carefully.

Soon, he randomly took a group and put them together in the alchemy furnace. Seeing that they were about to merge, before they could be reconciled, the two herbs, because of their mutual repulsion, immediately became Dregs.

For the next few days, Su Han constantly acted out the repulsion of various herbs, trying to find all the herbs that they could bear.

The herbs increased and decreased, the recipes were changed again and again, and the alchemy furnace was blown up again and again.

It can only be said that fortunately the quality of the alchemy furnace prepared at the beginning was good enough, otherwise it would not be enough for Su Han to put it on his own.

Nearly 10 days had passed, and Huang Yundan still hadn't refined a single one.

The little ball of light, who was still a little depressed at first, is now surrounded by Su Han, thinking about how to comfort him.

He failed every day and fried the furnace every day. As a bystander, he felt suffocated and couldn't hold on anymore.

Su Han is still full of enthusiasm, constantly researching and revising.

There were many times when Su Han was almost blown beyond recognition. Fortunately, he hid fast enough, otherwise it would have been a problem whether he could survive.

Another failure this day, Su Han sat in front of the alchemy furnace, muttering to himself.

"It shouldn't be, I have already calculated the best ratio, it shouldn't fail, why?"

"Obviously the ratio of yellow cloud grass is normal, magnolia, yellow flower, flying cloud folder... that's right!"

Su Han babbled, and then suddenly thought of something, and suddenly jumped up.

"Understood, understood! In addition to mutual generation and restraint, there is also the amount of medicine, and the power of the medicine consumed when they reconciled."

Immediately afterwards, I went outside to pick a lot of herbs, and then started practicing alchemy again.

The small ball of light looked at a large bald area that was about to be filled, and the whole ball was a little numb.

It has been many years since I have seen such a prodigal person.

Just when he was distressed, he suddenly heard the sound of turning on the alchemy furnace, thought he had failed again, so he went over to have a look.

It really succeeded, but it was just inferior.

Su Han seemed to have opened up the two veins of Ren and Du. In fact, he just found the right method and began to refine continuously.

From the beginning, only low-grade elixir can be refined, and slowly and occasionally a few middle-grade pills, followed by high-grade pills.

But it was as if it had reached its limit, every time the furnace was turned on, what came out was top grade, and the top grade could not be seen at all.

Where is the problem?
Su Han sat there alone, holding Huang Yun Dan in his left hand, and Ningshen Pill in his right hand, carefully looking at the two pills, thinking about the problem.

What is the reason?

Sit there all day and still haven't figured it out.

The little ball of light couldn't bear it anymore.

It is clear that as long as the high-grade Huang Yundan is placed directly on the formation, one can enter the next level.

In so many years of living, I have never seen such a picky person.

Just when he was going to remind him, Su Han was already observing with two yellow cloud grasses.

It's just a kind of herbal medicine, what's the difference between the two?
From Xiao Guangqiu's point of view, Su Han was wasting his time there.

I don't know how long I watched it, but Su Han went to the medicine garden, where there are a lot of herbs, all of which are the materials needed by Huang Yundan.

Like this kind of medicine garden, every time a level is passed, one will be reopened, and most of the medicinal materials planted in it are the medicinal materials needed for each level.

Generally, they are planted in densely packed places, and then multiplied there for many years, otherwise Su Han would not be allowed to study like this.

Soon in the dense yellow cloud grass, Su Han found something different.

As the name suggests, the yellow cloud grass is yellow in color, and there is a section of white rhizome near the root, which looks like a gradient color, which is very beautiful.

But there is also a yellow cloud grass, without the lower section, it looks yellow all over, and its fragrance is much stronger than the white rhizome with the section.

Comparing the two herbs, you will find that the yellow cloud grass without white rhizomes has very strong medicinal properties and is suitable for practicing alchemy, but it requires special techniques to stimulate its medicinal properties.

Perhaps it was also because of the lack of medicinal properties of Huangyun grass that it was not able to maximize its medicinal properties.

Thinking of this, Su Han deliberately sat down to pick out the yellow cloud grass without white roots at every moment, and then brought these herbs into the alchemy room.

The alchemy process this time was extremely long, compared to the usual time, it was nearly twice as long.

Soon a new elixir was refined, which was the top-quality Huang Yun elixir.

As the technique became more and more proficient, golden patterns of heaven began to appear on it.

It took a whole month to finally bring out the medicinal properties of all the herbs to the extreme.

At the highest level, only the three-pattern Huang Yundan could be produced.

In the next few levels, Su Han followed the same pattern and passed, and every time he did it to the extreme.

Although it took a long time, he could gain something big, but it was enough to benefit him a lot.

There are also innumerable pills that can be eaten in the space. It can be said that Su Han gained the most from this trip to the secret realm.

We soon came to the last place, which was different from the previous room, which was like a quiet tea room.

Sitting alone on the tea table, he looked very relaxed.

It's just that Su Han could feel that there was no anger in this person at all.

At this time, the little ball of light disappeared without knowing where it went.
