Due to Qin Feng's cultivation improvement, he came back a little earlier than before today. After coming back, he offered a treasure and held the red ginseng in front of Lao Xiang, who saw the nine-hundred-year-old red ginseng, and was shocked to say that Xiao Qin's luck was good, and then decided to go down the mountain in person in the afternoon to find some related medicinal materials to refine the Yiqi Pill. So the master and apprentice worked together, cleaned up the roe deer-like beasts, lit a fire and roasted them, and of course the eggs were put aside and cooked.

After the two of them had a good meal, Lao Xiang instructed Qin Feng to cultivate by himself, and then went down the mountain alone to find medicinal materials. Leaving the boy alone on the mountain, the boy obviously adapted to the time when Lao Xiang was away. After resting for a while, he picked up the herbs he had picked in the morning and prepared to start refining the elixir.

He took out a bronze refining furnace from the house, placed it on the stove that had been set up, and after the fire was lit, the young man sorted the herbs on the side and prepared to put them in the furnace to refine the pills. After a while, the Dan furnace was hot, and the young man hurriedly put in the medicinal materials and some auxiliary products, while controlling the fire with internal qi, so that the heat was distributed around the medicinal materials, and at the same time, using the internal qi, turning the medicinal materials in the Dan furnace from time to time.

In fact, the process of alchemy is to turn various medicinal materials from solids into pastes, then separate out impurities, refine the required essence parts, and then soften the essence parts of various medicinal materials together and slowly turn them into round pills. During this period, the requirements for the use of internal qi are very harsh, and if you are not careful, you will refine the waste pill, or you will not be able to become a pill at all.

Of course, there is also a way of alchemy, that is, with the help of some equipment to assist in separating impurities and softening medicinal materials with different medicinal properties, the requirements for internal qi are not so high, but this alchemy method is designed for some internal qi cultivation is not high, and the control of one's own internal qi is not fine enough, and the effect of refining the elixir is not as good as the effect of using pure internal qi to refine the elixir. Qin Feng's own cultivation talent is good, and Lao Xiang naturally would not teach Qin Feng this method of refining pills with the help of foreign equipment.

However, compared to the cultivation talent, the young man's alchemy talent is a little worse, and he has been studying alchemy for three years. So far, he can only refine some simple pills, and he can only succeed about eight times out of ten alchemies, and some high-level pills, only one or two times out of ten can succeed, so now Qin Feng is still mainly refining simple pills.

In the process of refining, we continue to figure out the familiar medicinal properties and the refined use of internal qi, in order to hope to increase the success rate of high-grade pills as soon as possible. Of course, the alchemy talent of the teenager is almost relative to his super cultivation talent, and at this age, compared to the average boy of the Azure Continent, Qin Feng's alchemy talent is also quite good.

It took more than an hour, and the basket of medicinal herbs collected in the morning was refined by Qin Feng, in exchange for round silt pills, cough pills, hemostatic pills, and the like, which were relatively low-level pills. These pills were of little use to Qin Feng, they were just used to practice their hands, so after refining, they were casually placed in the corresponding ceramic jars.

After refining the elixir and resting for a while, Qin Feng cultivated the swordsmanship, fist technique, and body technique in turn. Time flies, an afternoon has passed, Lao Xiang has not come back, rested and adjusted, lit a fire, took the remaining beast meat at noon to the fire and roasted it, while roasting the meat, while waiting for Lao Xiang to return. After the meat was roasted, when it was almost dark, Lao Xiangcai appeared in front of the young man with a cloth bag full of herbs.

"I found some medicinal herbs in the pharmacy in the castle under the mountain, and picked some more on the way back, these medicinal herbs combined with the red ginseng should be able to refine an upgraded version of the Qi Pill. Lao Xiang said to Qin Feng while placing the herbal cloth bag in the corner of the house.

"The upgraded version of the Qi Pill, is it still the Qi Pill?" Qin Feng asked casually as he greeted his master.

"Let's look at the effect of tomorrow's refining, maybe there will be surprises. Let's eat now. ”

After hearing this, Qin Feng hurriedly went outside the house to bring the roasted beast meat, put it on the wooden table in the house, and took out a few fist-sized wild fruits from a wooden box in the corner of the house, and placed them on the table. After thinking about it, he took out a small jar of wine and put it next to Lao Xiang.

The wild fruits are picked and stored in the woods on the mountainside, and the wine is bought from the city below the mountain by Lao Xiang, who is used to drinking a little wine at night. When eating, Lao Xiang will point out the problems that arise in Qin Feng's cultivation by the way, Lao Xiang himself has a high realm and rich experience, so he often points out the key points of the problems in the cultivation of the young man in one or two sentences, the young Qin Feng is talented and talented, so he often opens his mouth after listening to Lao Xiang's guidance, and some of the problems encountered are also solved.

After eating dinner unhurriedly like this, the two of them went to practice separately. Such days are very boring, but fortunately, both young and old are people who don't like to be too lively, plus they have to cultivate, and cultivation requires a quiet environment, so one old and one young, they stay on the top of this mountain for ten years.

When I got up early the next day, everything was as usual, but after lunch, Lao Xiang was about to open the furnace to refine the upgraded version of the Yiqi Pill, so Qin Feng followed behind in the afternoon to learn some techniques and techniques of alchemy. Speaking of Lao Xiang's alchemy level, it is barely the top in the Dongxing Dynasty, when he was young, Lao Xiang got acquainted with Bai Yu, a genius of the Tiandan Sect, and the two hit it off at first sight, so they asked each other for advice, Lao Xiang asked for alchemy methods, and Bai Yu asked for some bottlenecks in cultivation.

Later, Bai Yu also presented an ancient book of "Encyclopedia of Medicinal Herbs" to Lao Xiang. This ancient book later became Qin Feng's textbook for literacy and picture recognition. Ten years later, the knowledge of this ancient book has naturally been imprinted in Qin Feng's mind.

Lao Xiang opened up three hundred and sixty-eight trick points, and when he had no clue about the cultivation later, he concentrated on studying alchemy, and after years of accumulation, now Lao Xiang's general top-level pills can also be refined, but the success rate is about three or four percent, so Lao Xiang's alchemy level is barely top-notch. The success rate refers to the utilization rate of medicinal materials, the same medicinal materials, alchemy masters can refine hundreds of pills, while ordinary Dan masters can only refine fifty or sixty pills, and even worse ones can only refine twenty or thirty pills, or even one can't be refined.

Yiqi Dan is considered a high-grade pill, and the success rate of Lao Xiang Yiqi Dan is maintained at ninety. The upgraded version of the Yiqi Pill should be regarded as a top-level elixir, because according to Lao Xiang's speculation, the nine-hundred-year-old red ginseng is extremely strong, and the year of the medicinal materials matched with it is also not low, and the medicinal properties are naturally not bad.

After the items are ready, Lao Xiang first meditates and adjusts to improve his spirit to the best state. Qin Feng lit a fire on the side to raise the temperature of the Dan furnace first, while waiting to follow his master to learn alchemy techniques.

After the temperature in the Dan furnace increased sharply, Lao Xiang also adjusted his own state, grabbed the red ginseng and other medicinal materials that had been cut on the side and put them into the Dan furnace, while using the internal gas to spread the heat all over the Dan furnace, while constantly changing the mudra, his own internal qi, also with the handprint acting on the medicinal materials in the Dan furnace, constantly separated, purified, and then softened the medicinal properties, and slowly formed the Dan.

It took half an hour to refine the first furnace, and after opening the lid of the furnace, the five red pills were picked up by Lao Xiang in the air, and then placed in a small blue and white porcelain bottle. Next, he began to cast medicine and alchemy, but unfortunately, the three furnaces in the back were all refined, and none of them were refined.

Due to the deviation in the regulation of internal qi, the three furnaces of the pill all turned into a black paste. As a last resort, Lao Xiang stopped first and adjusted his state, a red ginseng, plus other medicinal materials, was divided into eight parts in total, and three parts were wasted at once, which was still a little distressing, after all, the top medicinal materials are not easy to find. While adjusting the state, he refined the remaining four medicinal materials, and in the end, he successfully refined two furnaces and abolished two furnaces. Fortunately, there were two successful furnaces, one furnace refined six, and the other furnace refined seven, so that eighteen upgraded versions of Yiqi Pills were successfully refined before and after.

After refining, Lao Shang summarized the gains and losses in the alchemy process with Qin Feng, and at the same time sighed that his alchemy level was not at home, if this was refined for the alchemy master of the Tiandan Sect, at least two or three times more pills would come out.

Qin Feng had never seen those alchemy grandmasters alchemy, and he felt that his master was already quite powerful, compared to the top elixirs, and he now even had a low success rate of high-grade elixirs.

Sighing and sighing, Lao Xiang also knows how rare the top pills are, and this time he can get eighteen, which is also a little satisfying. At that moment, Lao Xiang gave five pills to Qin Feng, and explained that he would take one at a time, at least a month apart, and then take the next one.

Since it took a lot of time to refine the pill in the afternoon, the daily cultivation in the afternoon was not carried out. After dinner, the old and the young went back to their rooms to experience the effect of the upgraded version of the Yiqi Pill.
