Back at the Hou Mansion, it was already dark.

In the next few days, Zhang Qingfeng found a secluded courtyard, and every day he did not leave the door, and devoted himself to refining Yuqing Dan for his father.

In order to repay Zhang Qingfeng's kindness, Qin Yun'er not only provided Zhang Qingfeng with free of charge in the medicinal material warehouse in the auction house, but also gave him a high-grade alchemy furnace that had been treasured for many years.

Alchemy is a university question, extremely complex, and there are many people who learn it, but few people who succeed in it.

Knowing medicinal materials, distinguishing medicinal herbs, understanding pharmacology, and memorizing formulas are only the basis for entry, and it takes five to ten years for introductory training alone.

A qualified alchemist has to go through countless failures before he can master the refining technique of an elixir, and the high cost is by no means affordable for ordinary people.

The Great Zhou Kingdom is just an insignificant small country in the eastern region of the Great Yan Continent, and among the nine grades of alchemy, only the royal alchemist of the royal family can refine the three-grade pill, and it is still the primary pill of the three-grade.

Although the other Hou Mansions have also invested a lot of financial and material resources in cultivating alchemists, they are limited by their talents, and they are thankful that they can produce a first-class alchemist.

In addition to medicinal herbs, a suitable Dan furnace is also related to the success or failure of alchemy, and various restrictions have created a scarcity of alchemists.

Scarcity is expensive.

The scarcity of the number of alchemists has made them a noble position.

In the Great Zhou Kingdom, a second-grade alchemist can enjoy the respect and respect of a prince and general.

The three-grade alchemist is enough for the Great Zhou Emperor to regard him as a distinguished guest.

But who would have thought that in the increasingly dilapidated Wu'an Hou Mansion, there were people hiding in a secluded courtyard refining the three-grade pill, or the high-grade pill Yuqing Dan among the three grades!

"Young master, three coins of bamboo leaf grass, five coins than white peony, six roots of the tongue, simmer slowly for an hour, and then burn a stick of incense for a while, and then open a cup of tea, let the medicinal liquid boil, volatilize six points of medicinal power, and then add silver lotus seeds, right?"

Xiaochan added fire to the Dan furnace while repeating Zhang Qingfeng's explanation.

"That's right, Xiaochan, do you remember it so clearly? What about after adding the silver lotus seeds?"

Zhang Qingfeng, who was about to sit and practice for a while, was impressed by Xiaochan, he only said the refining process once, and he didn't expect Xiaochan to remember an eight-nine and ten, if you want to learn alchemy, the first thing you have to pass is to memorize, this little girl's memory ability surprised him greatly.

Xiaochan saw that Zhang Qingfeng's eyes were full of approval, and she was overjoyed, and then told the following refining process.

"Okay! That's right! Genius, really genius! Xiaochan, you have such a memory that you can't forget? Why didn't you say it earlier?"

Zhang Qingfeng was overjoyed, although Xiaochan didn't say it word for word! But it was not much different, especially the boring and tongue-twisting pharmacology that was the most difficult for an alchemist to remember, she actually memorized it in an orderly manner. That's talent.

Xiaochan was embarrassed to be praised, threw the firewood in her hand into the stove, bowed her head shyly and said: "Young master, don't make fun of Xiaochan, you used to scold Xiaochan for being stupid, always losing everything, and being confused every day, have you forgotten?"

Zhang Qingfeng paused for a moment, and quickly flipped through the memories of Xiaochan, and sure enough, it was so.

The maid, who had grown up with him, was sold to the city by his family when he was five years old.

It happened that she was bumped into by her mother Qin Huiying that day, and she thought that the little girl was white and cute, so she bought it back to the Hou Mansion and became a maid.

said that she was a maid, the virtuous and kind-hearted Qin Huiying has always treated her as half a daughter, as she grows older, the little girl grows more and more peugeot, but her memory is not good, she is always lost, and the former advocate Qingfeng also gave her a nickname called Little Confused.

Zhang Qingfeng is so knowledgeable, as a martial arts emperor who moved the continent thousands of years ago, he has received countless apprentices, and he has seen thousands of Dan Dao geniuses, but there are not many talented geniuses like Xiaochan.

"Xiaochan, do you want to become an alchemist?"

Zhang Qingfeng had a love for talent and decided to teach Xiaochan alchemy, although a good memory does not mean how high he can achieve in alchemy, but firstly, he needs an assistant in alchemy, and secondly, from Xiaochan's excited eyes, he instinctively feels that even if Xiaochan can't become a nine-grade alchemist, given time, it shouldn't be a problem to practice a five-grade pill.

Zhang Qingfeng's cultivation is not there, but his eyesight is still there.

"Alchemist?" Xiao Chan covered her mouth in surprise, stared at her big watery eyes, and said, "I want to, but Xiao Chan is just a maid, how can she be qualified to cultivate." Besides, the alchemist is very money-burning, and the disciples accepted by the Jindan Hall in the south of the city will have an entrance fee of 1,000 white crystals. ”

"You just have to learn if you want to. ”

Zhang Qingfeng couldn't explain too much to Xiaochan, and said: "From today on, you will follow the young master and me to make alchemy, and you will do whatever I ask you to do, understand?"

Xiao Chan nodded obediently: "Xiao Chan knows, Madam said yesterday that she will listen to the young master for everything in the future, but young master, you have wasted so many herbs, can you refine them successfully? Also, what kind of pill are you going to refine?"

Obviously, Xiaochan is still not very confident about the alchemy ability of this young master, who has been depressed for more than ten years, and now suddenly seems to be a different person.

After all, the two grew up together since childhood, and Xiaochan never saw Zhang Qingfeng learn alchemy.

Zhang Qingfeng looked at the Dan furnace and said, "The pill that the young master wants to refine is called Yuqing Dan, which is an extremely complex and difficult pill to practice, however, alchemy needs to be gradual and gradual, so I will teach you from the beginning." ”

Alchemy is boring and boring, Zhang Qingfeng was already a pharmacist of the Nine Pins Dan thousands of years ago, and the refining method of the Sanpin Yuqing Dan has long been familiar with it, and the challenge he faces now is that his cultivation is too low, and he can't turn the spiritual energy in his body into Dan Fire Alchemy, the success rate will be greatly reduced, and the alchemy time will be doubled, just enough to pass the time by teaching Xiaochan alchemy.

This began to teach, and Zhang Qingfeng was taken aback again.

He found that the maid Xiaochan, who grew up with him since childhood, had an amazing talent in alchemy, and no matter how difficult the pharmacological Dandao was, it only took Zhang Qingfeng to explain it three times at most, and the score was exactly right!

Not to Zhang Qingfeng's expectations, the first furnace of pills ended in failure due to the lack of the stimulation of the pill fire, and the refined pill completely turned into a poison pill.

Three days later, the second furnace of elixir was released, although it was much better than the first furnace, but the toxins still accounted for more than sixty percent, and the toxicity far exceeded the medicinal properties, and it was also refined.

Xiaochan cherished this opportunity for alchemy very much, as if she was treasure something, she carefully wrapped up the two failed works and hid them. Zhang Qingfeng, who saw this scene, became more and more satisfied with the little girl.

Failed twice, wasted more than half of the medicinal herbs, worth more than 10,000 white crystals, this money is not a small amount in any family of the Great Zhou Kingdom, let alone the declining Wu'an Hou Mansion?

But Zhang Qingfeng not only did not feel lost, but became more and more excited, because from the failure, he found a new way to refine the Jade Qing Dan.

After another three days, Zhang Qingfeng stared at the Ding furnace, which no longer emitted heat, and clenched his fist at the small hand on the side, and Xiao Fluttershy shouted in a deep voice with an excited face: "Open the furnace!"

"Okay!"

Fluttershy took two steps forward, and neatly inserted the medicine fork in her hand into the lid of the furnace, twisting it hard, only to hear a loud bang from the canopy, and the lid was blasted open by the heat of the furnace, and eight thumb-sized pills were sprayed out.

Zhang Qingfeng had already prepared, and with a wave of his hand, the eight pills were rolled into his sleeve, and as his body rotated, he only heard a series of crisp sounds, and they were all thrown into a bucket full of cold well water on the side.

Fluttershy's waist twisted, flexible like a spring swallow returning from the north, and she threw herself over the bucket and looked inside, and said in surprise, "Young master, look, it's all white, it's all white, it's all white, it's done!
