In the following time, Zhang Ran went to the county government and asked the county magistrate for a ten-day long vacation.

The county order was extremely dissatisfied with Zhang Ran's lazy behavior of fishing for three days and drying nets for half a month, thinking that he wanted to be lazy, and for this reason, the county order also seriously criticized and educated Zhang Ran:

"With your work attitude, how will you be a good official in the future! How dare you ask for leave! ”

Leave? Scold! No way!

Obediently give this official ninety-nine-six!

"Don't be angry."

Zhang Ran said sincerely:

"It's not that I want to be lazy!"

"The county also knows that I have learned the art of alchemy, but I have not had time to do alchemy for a long time recently, and after a long time, I am afraid that I will regress......"

The county order's face softened slightly:

"So you asked for leave, do you want to refine a few furnaces of pills to try your hands and deepen your Dan technique, so as not to regress?"

"Exactly!"

Zhang Ran bowed:

"Please allow the county."

Hearing this reason, although the county order is still dissatisfied, it is not incomprehensible, after all, for Danshi, alchemy is the foundation of his life, and it is really difficult for him to stop this kid from alchemy.

So, the county magistrate snorted coldly:

"Okay, the official has approved, at most fifteen days, and it cannot be overdue."

"Thank you for the kindness of the county!"

Zhang Ran was about to thank him, but he listened to the county order:

"Anyway, if you come back as soon as possible, there will be big people passing through here in the near future, so as not to miss this matter and cause the big people to be unhappy......"

……

"Big shots? How big is it? ”

Is it as big as Zhao Gongzi who paid for the whole audience?

Zhang Ran returned to the small courtyard, still thinking about the "big man" mentioned by the county order.

Then he shook his head and put the matter behind him for the time being:

"No matter what kind of big man he is, even if the emperor comes, he can't stop the poor Dao alchemy!"

This alchemy is not ordinary, it is different from the low-level pills such as the detoxification pill that he refined before, what Zhang Ran wants to refine, but it is the high-level pill of the Eight Classics:

Dragon Tiger Jindan!

This is the first time that Zhang Ran has combined the theory of Danshu in another world with the theory of Danshu in this world, and carried out a major move to practice!

Boom~

Zhang Ran took out the Dan furnace placed in the red envelope and smashed it on the grass in the courtyard, making a dull metal sound.

"This Dan furnace given to me by Brother Tian, although it is not as good as the one handed down by the ancestors, but it also has the function of making a fire without firewood and becoming a Dan by itself, which is an excellent quality furnace."

was about to start alchemy, Zhang Ran slowly entered the state, and the whole person became extremely calm and serious.

The fact that there is no interference from external objects during alchemy is a proof of the qualifications of a Dan master, and Zhang Ran naturally has this basic quality......

"Daoist Zhang, do you want alchemy?"

The muffled sound of the Dan furnace smashing on the ground alarmed the green snake who was swallowing spiritual energy in the house, and the tiger who was sleeping lazily.

The two of them got out of the room and walked to Zhang Ran's side, looking at Danlu and Zhang Ran curiously, and the green snake also asked each other.

After all, Zhang Ran had never practiced Dan at home, at most, he used snake venom to rub a few antidote pills, and they had really never seen this kind of big scene of using the Dan furnace.

However, Zhang Ran, who was in a sinking state, ignored her at all, and only concentrated on preparing for alchemy......

"Dancai."

Zhang Ran took out all the Dan materials collected in the past few months from the red envelope:

The last time I killed six wild cultivators, I touched the corpses and touched a few bottles of strange poison, the leftovers of the pill materials that were deducted when I helped the qi refiner refine the pill, and the snake venom and dragon clothes obtained from the green snake, etc......

Mouth area!

The green snake was stunned as he watched the dozens of familiar snakes molt, and suddenly retched.

She hurriedly distanced herself from Zhang Ran, for fear that this pervert would make some disgusting moths:

"This guy is taking my molten skin alchemy, shouldn't he want to eat it?!"

Belch...... That's disgusting......

Zhang Ran didn't care what she was thinking, she just pondered the medicinal properties of the pill:

"The basic theory of medicinal properties is almost understood, but I still have too few things at hand, and it is far from enough to dispense sufficient medicinal properties."

If the ancestral master's medicine depot was still there, and then the alchemy props were fully prepared, with Zhang Ran's Dan technique, if he was familiar with the basic medicinal property theory, he could try one or two pills below the immortal level.

And its probability of becoming a Dan can be directly pulled out to more than eighty percent, slightly familiar with the familiar feel, ten percent is not a problem!

"I can't help it, I'll just use it......"

Open the independent fire of the Dan furnace and turn on the fire, the faint red spiritual fire rises, and the surrounding area is gradually becoming hotter, and the tiger who is afraid of heat hurriedly runs away, and lies down next to the green snake, and a tiger and a snake look at Zhang Ran alchemy intently......

Taking advantage of the spiritual fire to warm the furnace, Zhang Ran closed his eyes, and quickly deduced the theory of medicinal properties in his mind.

After a moment, he opened his eyes:

The success rate of deduction is 90%!

Well, steady. (Gou Shengkutai)

Although the Dan materials at hand are not only small in variety and low grade, it is not impossible to refine the Dragon Tiger Golden Pill:

"The full version of the Dragon Tiger Golden Pill is almost the same level as the Immortal Pill, and with what I have at hand, it is impossible to succeed."

"But...... Why do you need to refine the full version? ”

The castration version of the castration version...... That's enough!

"It's just that I'm afraid this can't be called [Dragon and Tiger Jindan], and it can barely be regarded as a [Cat and Snake Jindan] ......"

In just a while, the spiritual fire had already heated the Dan furnace, so Zhang Ran began to release the medicine......

The green snake and the tiger watched as Zhang Ran first put more than half a catty of spirit essence into the furnace, and a large amount of pure spiritual energy was emitted from the furnace.

One word: trench!

Two words: waste!

The two of them don't understand Danshu, they just think that Daoist Zhang (two-legged beast) is too extravagant and wasteful, so many spirit spirits, they just put it away, and they are completely lost.

How nice it would be if you fed them both......

Zhang Ran first used the spirit essence cultivation furnace, but also to avoid the fire being too strong and burning the Dan materials behind.

After that, he slowly put in some untreated primordial pill materials, strictly grasped the heat, refining not more than one breath, and refining one breath more, extracting the medicinal essence as much as possible.

Yes, medicinal essence, no serious Dan master directly refines the original pill materials such as scales, feathers, and ores into pills......

Alchemy is a complex science, and it is also a whole that is integrated by a series of unrelated steps.

It is not simply to put a bunch of strange Dan materials in the Dan furnace, and then through the operation of the Dan Master and the gods, the seal recipe or something, you can really produce the Dan.

The real alchemy includes a series of steps such as material selection, extraction, detoxification, medicinal property ratio, etc., during which the Dan Master has to control the heat, and then extract all kinds of semi-finished Dan materials in different categories, and then mix the semi-finished Dan materials according to the [Junchen Zuo Envoy] to match the medicinal properties and so on......

It is really not only a technical work, but also a hard work!

There are Dan masters who can't stand these many trivialities, so they recruit other people who know Danshu as assistants, which derives the "fire blowing boy", "alchemy boy", "medicine test boy" and other Dantong professions......

Zhang Ran doesn't need a boy's assistant, he can handle everything alone, not because he is talented, but because this is the basic operation of the descendants of the "Danding faction", he has already practiced experience.

……

Zhang Ran extracted various medicinal essences in different categories, and under his skillful Danshu operation, this even had a somewhat pleasing artistic sense......

"I've done the first step!"

After Zhang Ran extracted the last medicinal essence, he finally breathed a long sigh of relief.

Looking up at the sky, the sun has already set, the sky is dark, and even the bright white moon disk is hanging high in the sky, which seems to have a kind of cool pleasure.

But this cooling sensation will be completely dispelled by the high-temperature Dan furnace in front of you in an instant......

"This ...... It's a little bit of the intoxication when I was refining the elixir! ”

Zhang Ran smiled with satisfaction, this tedious step did not make him feel irritable, on the contrary, he even enjoyed this strange sense of fulfillment, perhaps it was because of this feeling that he was able to refine the pill for more than twenty consecutive years, and finally refine the elixir......

Snore~

Zhang Ran turned his head to look and found that it was a tiger, and under the dim and distorted light of the fire, the tiger who was lying on his stomach watching his alchemy in the distance had quietly fallen asleep.

"Daoist Zhang, have you finished refining?"

The green snake was coiled next to the tiger, she didn't fall asleep, and when she saw Zhang Ran turning her head, she asked curiously.

"No, it's early."

Zhang Ran chuckled, then turned back and continued to refine the pill.

"The first step is complete, and the next step is to refine the Dan embryo!"

Dragon Tiger Jindan, the word Jindan is not taken randomly, it really has to be refined with metal as a material!
