After a while, under Lao Ji's control, the fire slowly became smaller and weaker. Then, he faced the Dan furnace with his right palm on the top, and held up his left palm on the bottom, explaining: "Now is the final stage of fire control. ”

After more than ten minutes, Lao Ji's left hand was recovered, and with a flick of his right hand, the furnace fire was instantly extinguished. He then said: "This method of stopping, after seeing the right time, you must quickly and accurately extinguish the fire. Don't underestimate this step, if you don't do it well, it will affect Cheng Dan, and sometimes you may lose your efforts. ”

Miao Fu nodded vigorously beside her and sighed: "Alchemy is like embroidery, it's really a meticulous job." ”

"Apprentice, the last step of alchemy is to gather Dan and collect Dan, this is actually two steps, and it is also the key to finally becoming Dan, you have to pay attention." Lao Ji admonished.

Then, his palms changed in a circle, and strands of pure white true qi erupted like a thick mist, wrapping the Dan furnace two feet above the ground, and floating in the air.

After a while, I heard the clanging sound of the pill hitting the wall in the furnace.

At this time, Lao Ji saw that the time was ripe, and gently pushed forward with his right palm, only to hear a soft "bang", the lid of the furnace was lifted suddenly, and a pink pill flew out of the furnace mouth.

Lao Ji held up the lid of the furnace with his left palm, and grabbed a small jade bottle beside him with his right palm, the mouth of the bottle was facing upward, and he quickly stretched forward. A ray of red light fell from the sky, and he had already caught the elixir steadily.

Miaofu's eyes widened, and she saw the elixir dripping and turning in the jade bottle, making a crisp sound of "crackling".

Lao Ji looked at Miaofu with a smile, and raised his hand to throw the jade bottle over. Miao Fu took the bottle and carefully observed the freshly baked blood return pill. At this time, there was still a trace of white gas on the spherical pink elixir.

"Master, there is only one grade of the pill in the Taibai Xuanwu Danlu, but the pill like the Blood Returning Pill is different, how can it refine the Yellow Grade to the Heaven Grade?" Miao Fu asked.

After pondering for a few seconds, Lao Ji replied: "Today's doctors can prescribe different prescriptions for the same disease according to different people, times and places, which is different treatments for the same disease. Doctors prescribe this way, not to mention different grades of pills? ”

He then explained, "Although the basic principles of the elixir that can be refined into various grades are the same, the types and quantities of medicinal materials used, as well as the steps and techniques used in alchemy, are very different, and some have even become more thorough, as if they were refining another elixir. ”

"Therefore, in a strict sense, the same name pill of the Yellow level and the Heavenly level, although their medicinal effects are the same or similar, they are no longer a pill in essence."

"For example, the Yellow-level Blood Returning Pill is for quenching body martial artists, and the Heaven-level Blood Returning Pill is for treating Great Grandmaster martial artists, while the body qi and blood and musculoskeletal of quenching and Great Grandmaster martial artists are very different. Think about it, it's the same Blood Returning Pill, can the Yellow Level and the Heaven Level be the same? ”

Miao Fu nodded thoughtfully and said excitedly, "Master, I understand. None of the pills are dead, and the techniques and steps of alchemy can also be changed. As long as it is useful for a certain injury or cultivation, there can be corresponding pills and pills. ”

When Lao Ji heard his apprentice say this, he wondered if he had lived for so many years in vain. He was amazed by Miaofu's alchemy understanding and creative thinking, and he was also full of expectations for her to open up a new world in the field of alchemy in the future.

At this time, Miao Fu played with the jade bottle in her hand, looked at the small pink ball inside, and said incredulously: "The pill is so beautiful!" Master, the Blood Returning Pill is different from the tablets in the hospital! So how do you let ordinary martial artists outside take it? If they saw it, wouldn't they suspect or even know that it was an elixir? ”

Lao Ji smiled and said: "Apprentice, the country regards alchemy as a strategic business, and alchemists, especially high-level Danshi and Danshi, are under key protection. ”

"Because many of the medicinal materials used in alchemy are difficult to find, and the amount of pills refined is not much, they are generally used by political Fu, high-ranking officials of the army, and high-ranking martial artists of the Martial Alliance, so I don't have to worry about leaking secrets."

"Of course, for the sake of people's livelihood and development, if you want to supply it to middle and low-level warriors or ordinary people at some time, you must adopt some cover-up methods and put it into the market in Haiti."

Miao Fu suddenly became interested and asked, "Master, how can you hide it?" How to calculate the price of pills in the market? ”

"You little money fan." Lao Ji joked, and said: "Pills are generally smaller than ordinary pills, and most of them are spherical. Therefore, there are many ways to change its appearance, such as wrapping a layer of sugar coating on the outside of the elixir, and grinding it into powder and then reshaping the shape. ”

"Although the efficacy of the pill will be damaged to a certain extent after being crushed into powder, it is even less noticeable. Therefore, there are many ways to use this method. ”

Lao Ji took a sip of tea and continued: "As for the price of the pill, it is different. Apprentice, for example, the yellow-level mid-grade blood return pill in your hand, if you sell it privately, it can bring nearly double the income, reaching more than 100,000 yuan. I used to sell a grain of raw bone pill to Shencheng martial artists, and the price reached more than 2 million yuan. ”

Shencheng is the economic center of Yanguo, where there are many high-rise buildings, commerce and trade are developed, and there is already the prototype of an international metropolis. There are many wealthy clans in Shencheng, and the density of high-strength warriors is second only to the capital.

Regarding the sale of pills quietly and privately, Lao Ji emphasized that they could only be sold to trustworthy people. For the sake of secrecy, it's okay to do such things occasionally, but not often.

Miaofu listened to the price of the pill introduced by the master, and her little heart beat non-stop. She has always been worried about how to repay her master's loan of one million, if the pill is so valuable, she will become a little rich woman in the future.

However, Miao Fu sensitively thought of a question. She asked, "Master, if the elixir we refine is normally provided to the state and the Martial Alliance, will it still be considered profitable?" ”

Lao Ji laughed and said, "My apprentice is an elf ghost, how can the pills that are normally supplied not be money?" Otherwise, the alchemists will have to drink the northwest wind. Although the income from the pill offered is much lower than that from selling it privately, there are additional benefits after the pill is provided to the state and the Wumeng. ”

"Because, the state and the Martial Alliance will exchange more medicinal materials for pills, and they can exchange them for many things that are difficult to obtain through normal means, which is not something that ordinary family sects can do. So, we only make money and don't lose money. ”

"Master, alchemy is very good, and you can make a lot of money, why do you want to become a teacher?" Miao Fu asked with a wink, puzzled.

"Boy, money doesn't appeal to me anymore, I don't lack that stuff. I have always enjoyed working with students, and it is only at school, with you lively and lovely students, that I can feel fun and meaning in life. After Lao Ji finished speaking, his eyes stared blankly in one direction, silently thinking about something.

Alchemists not only have a respectable status and wealth, but most of them are relatively arrogant and prefer freedom to constraints. Professor Ji, who is an old playchild, loves the blue sky and white clouds, birds and flowers, is willing to mingle with innocent and romantic students, and hates secular deceit and power disputes.

For many years, the country and the Wumeng have vied to recruit Lao Ji, an outstanding Danshi, but he has not been moved. After a long time, he felt bored, so he left the Ji family in the capital and came to Southwest Shu alone to serve as a professor, and he was angry with Ji Lexuan for a while, annoying the people in the family.
