Suning Yu also learned about some situations, since everyone could not use the true yuan to refine, a new industry was born, that is, the refining industry, and everyone who needed to refine would go to some places that provided high-temperature flames.

When Su Ningyu came to a place called the refining station in the city, he found that this was indeed a new industry, there were a large number of rooms here, and there was a refining furnace in each room, and these refining furnaces were somewhat like the small refining furnaces on the earth, but it seemed to be built with a formation, and the temperature of the flames inside could also be adjusted.

When I inquired about the price, I found out that every room here can be rented, and it is 500 yuan per day.

Su Ningyu just came to feel the flames, so he rented it for a day.

After entering the inside, a Dan furnace that was not too big was placed there.

After taking out all the spirit grass he brought, and after thinking about the alchemy techniques he knew for a while, Suning Yu began the first alchemy process.

The first time was naturally to take out all the spirit grass of the Danfang that he could get, and then, Suning Yu started the first refining.

Su Ningyu didn't care about success or failure, what he cared about was his next deduction.

Sure enough, there was no surprise, the first furnace was a failure.

After the failure, Su Ningyu closed his eyes and recalled the refining process, and the data had been obtained.

The divine sense is extremely powerful, and Sun Ningyu knows every step in his heart.

After this refining, Su Ningyu was there to predict what might happen, and then, again and again, he adjusted some of the techniques he might make, and continued after failure, and then it kept failing, and kept going.

After spending five hours, Su Ningyu knew that he had completely mastered the refining method of Pei Yuan Dan.

Of course, this was only the first step he had made, and then, according to the theory of the medicinal properties of those cheap spirit herbs. Suning Yu made all kinds of matching.

This time, after he learned about the medicinal properties of a certain high-priced spirit grass, he used some cheap spirit grass to match it, trying to get the medicinal properties of that high-priced spirit grass.

After spending another three hours, Suning Yu was able to figure out one of the spiritual herbs.

After resting for a while, after eating some things, Su Ningyu continued to study the properties of spiritual herbs.

That is to say, Su Ningyu has the ability to predict and deduce, if it is another person, just such research is enough to go bankrupt, and the consumption of a large amount of spirit grass is an astonishing data.

It's not that those rich people can't do this kind of research, the main thing is that Pei Yuan Dan is not a great elixir, and it is inappropriate for rich people to spend so much time and spend a lot of money to do this kind of research.

Two hours later, Su Ningyu also refined the medicinal properties of another high-priced spirit grass with cheap spirit grass.

I have to say that Su Ningyu's ability to deduce is very powerful, and Suning Yu himself feels that with such means, he has a hole card no matter what he does next.

Two hours to go!

Su Ningyu's whole body is relaxed now, he knows that he has really succeeded, he has already calculated the price, if it is a normal situation, the cost price of a furnace of Peiyuan Dan is five thousand yuan, and each grain is one thousand yuan, under normal circumstances, each furnace refines five grains to protect the capital, under normal circumstances, everyone can refine six to seven pills in one furnace, and only those very powerful Dan masters can refine more than seven pills.

Now if Suning Yu can use cheap spirit grass to refine, the cost of a furnace is about 1,000 yuan, only one pill of Cheng Dan is needed, and it is almost guaranteed, if it is refined too much, it will be very profitable.

Now it's time to refine it with cheap spirit grass!

Su Ningyu first deduced the refining method of Pei Yuan Dan, and now he is proficient in the refining method of Pei Yuan Dan, and now the main thing is to extract each medicinal property.

Soon, the medicinal properties of a kind of spirit grass were extracted, and then, Suning Yu began the process of fusing the medicinal properties.

The most important part of the refining of the elixir is fusion, which has many tricks.

Su Ningyu kept pressing some buttons on the refining furnace to adjust the flames.

In the past, cultivators used their own true fire to adjust when refining, but now it is not so complicated, they only need to press the button on the refining furnace to adjust the flame, which is convenient and fast, and the adjustment is still very in place.

There was a little problem with the first furnace, and it turned out to be a failure.

However, this is not much of a problem for Su Ningyu, anyway, what he needs is the first refining process, followed by deduction.

After spending another half an hour, Su Ningyu successfully deduced this fusion method.

When predicting the result of refining, a smile appeared on Su Ningyu's face, this time it was really no problem.

Seeing that there was still an hour left in the time, Su Ningyu quickly put in the spirit grass, and then, the fusion began again.

This time, because of Su Ningyu's preparation, it was very easy to refine a furnace of elixir.

Three grains!

Although there were not many pills refined this time, only three, this was enough to show that his method was feasible.

When he tested the medicinal properties of the pill with a medicine tester placed in the room, Su Ningyu was even more satisfied.

The pill is divided into upper, middle and lower grades, and then there are four perfect grades, and now that the pill he has refined has reached the middle grade, then this pill can be sold for 1,050 yuan, which is 500 yuan higher than the lower grade pill.

This time, Su Ningyu spent the most money on the refining of the original furnace of pills, which used the spirit grass on the pill, and the furnace was more than 5,000 yuan, and then there were two furnaces of spirit grass to extract the medicinal properties, which cost about 2,000 yuan, and the other was the fusion refining, which cost 1,000 yuan, and the cost of his chong was about 8,000 yuan.

This time, the cheap spirit grass cost thousands of yuan to buy, and what to do now is to select those cheap spirit grasses that can be used and refine them.

I have to say that the machine refining method used now is really fast, and only needs to make some adjustments, and after putting all the spirit grass into it, you can refine the pills in batches.

However, Su Ningyu didn't do this, he still found a situation, if he did that, the success rate was very low, after all, even if it was a cheap spirit grass, the medicinal properties contained in each plant were different.

Therefore, Su Ningyu also spent some time carefully extracting some medicinal properties until he thought it was reasonable.

The spirit grass brought in was almost used up, and many spirit grasses were discarded, and in the end, only six pills were obtained.

spent more than 10,000 yuan to buy the spirit grass, and only then did he get six pills, even if all of them were medium-grade, he came back for less than 10,000 yuan, which seemed to be a loss, but he got a new Peiyuan Danfang, which was the result of a big profit for Su Ningyu.
