After settling down, Lu Xiaotian took out the pill furnace again, cleaned the impurities in the cauldron, and started the fire again to refine the pills.
The most difficult part of alchemy was the control of the fire and the time to open the furnace. Usually, it would take nearly four hours to refine a Qi Gathering Pill. Lu Xiaotian had to pay attention to the fire at all times. When the fire was too strong, he would remove a little spiritual charcoal. When the fire was too weak, he would add charcoal.
However, these two points depended on the experience of the alchemist. It was not easy to refine pills with just one pill.
Even a beginner alchemist was very popular in Full Moon City because alchemy was not only difficult, but also a profession that consumed a lot of spirit stones. For those who had just learned alchemy, the rate of producing pills was often ridiculously low. Often, they might not succeed once in a few or even a dozen furnaces. To increase the rate of producing pills, it required long-term practice and accumulation of experience.
Ordinary rogue cultivators were simply unable to bear such a burden in the early stage. Most of the alchemists in Full Moon City were cultivated by the family that controlled the various pill shops using the family resources.
And the trained alchemists needed to work for the pill shops of the various families. Usually, the pills sold to the outside world were low-grade pills, and the better quality middle-grade and even high-grade pills were taken by talented people in the cultivation families or appeared in the auction house and sold at an astonishing price. Therefore, the strength of people from the cultivation families was often stronger than ordinary rogue cultivators.
Apart from the daily cultivation time, Lu Xiaotian stayed in the courtyard to refine pills for nearly ten days in a row. He had refined seventeen furnaces of pills in a row, and the remaining spirit stones were almost used up. Such a high failure rate made him a little discouraged. If it weren't for the space in the enchantment that could cultivate the purple spirit grass, this intensity of alchemy would not have been able to continue.
The value of seventeen purple spirit grass alone was as high as forty spirit stones in Full Moon City. If the auxiliary medicine was included, the spirit stones that Lu Xiaotian wasted in nearly ten days was very astonishing for a cultivator in the Qi Refining stage.
However, after so many failures, Lu Xiaotian summed up a set of refining methods for Qi Gathering Pill. He also had a certain understanding of the fire and opening time. Lu Xiaotian was looking at the blazing charcoal fire under the cauldron with rapt attention.
At this time, he was no longer like when he first started refining pills, taking out the spiritual wood charcoal when the fire was too big. His previous failure allowed him to roughly know how much spiritual wood charcoal was needed to increase the firepower. This was the experience gained by alchemists over a long period of time.
Nearly two hours later, the familiar fragrance once again wafted over. Lu Xiaotian's heart tightened. If he failed again this time, he could only sell the remaining twenty talismans in his possession in order to continue refining pills.
He focused his mind and calmed his Qi. Open the furnace!
As he opened the lid of the cauldron, a warm and familiar medicinal fragrance assailed his nostrils. He saw two milky-yellow medicinal pills lying quietly inside the small cauldron. One of them had a particularly rich fragrance, and its milky-yellow surface actually had two tiny pill veins.
"I even managed to refine a middle-grade Qi Gathering Pill!" Lu Xiaotian was pleasantly surprised. His hard work for more than ten days had finally paid off. This kind of reward after going through hardships was far more significant than the two pills.
After the heat on the surface of the two perfectly round and plump spirit pills dissipated, Lu Xiaotian put them into small bottles respectively.
He had to strike while the iron was hot. Taking advantage of the fact that he had successfully refined a furnace of Qi Gathering Pills, he would refine a few more times today.
With enough seeds in his hand, Lu Xiaotian refined seven more times in a row, using up all the purple spirit grass in the enchantment. He succeeded three times, but only one medicinal pill was produced each time. He didn't refine two pills like before.
However, he was quite satisfied with this result. Even if some of the alchemists in the Full Moon City had decades of alchemy experience, it was already a very good result to succeed three to four times out of ten.
Alchemy was a skill that was very particular about the realm. The control of the fire and the opening of the furnace were not constant. Different Purple Spirit Grasses had different growth rates and states.
A brilliant alchemist would have a prediction of the spiritual grass in his hand and roughly what kind of fire to use. This judgment may also be wrong, so during the refining process, the alchemist would also slightly adjust the fire and the time to come out of the furnace according to the changes. However, no matter how powerful the alchemist was, he couldn't guarantee that his judgment was 100% correct. If there was a slight mistake in the middle, it would lead to the failure of the furnace of medicinal pills.
Therefore, an experienced alchemist could only maintain a certain success rate.
The reason why Lu Xiaotian could achieve such a high rate of pill production in such a short time, in addition to the improvement of his alchemy skills. More importantly, he had refined the same kind of medicinal pill so many times in a row, which other alchemists didn't have. In addition, the purple spirit grass growing in the enchantment was not affected by external conditions such as wind and rain, and their growth was relatively consistent. This also improved his pill production rate.
After refining the last purple spirit grass, Lu Xiaotian put away the small cauldron with satisfaction. He took out the middle-grade Qi Gathering Pill. Good medicinal pills naturally should be kept for his own use. Now it was time to try the effect of the medicinal pill.
Lu Xiaotian directly sat on the stone chair in the small courtyard and took the middle-grade Qi Gathering Pill. The Qi Gathering Pill slowly melted in his body, turning into a gentle flow of heat that flowed through his limbs and bones.
In the past, it would take him nearly twelve hours to refine the medicinal efficacy of the Qi Gathering Pill, but now that he was at the fifth level of the Qi Refining Realm, it only took him less than two hours.
The spiritual qi that could not be contained in his meridians appeared in the enchantment as usual. After absorbing the medicinal efficacy in his meridians, Lu Xiaotian's Life Essence chased after the spiritual qi in the enchantment. Then he scattered the purple spirit grass seeds, and crushed a piece of spirit stone into powder and sprinkled it on the soil next to the purple spirit grass seeds.
Previously, when he was refining pills, he had used up all the purple spirit grass seeds. When he was cultivating them, he was very anxious because the spiritual qi in the air was floating around, and it was very difficult for it to directly float to the purple spirit grass seeds to be absorbed. Later, he had no choice but to use spirit stones, and he found that he could use his mind to control these spirit stones and crush them.
When using spirit stones, he also had to pay attention to them. After all, he had metal, wood, water, fire, and earth spirit stones. Only the rare ice, wind, and thunder spirit stones were not available. Water was the source of life, but it could not be used too much, otherwise the soil would be too warm and moist for the purple spirit grass to grow.
Earth spirit stones could enhance the spiritual qi of the soil. Wood spirit stones were also the foundation of the purple spirit grass, and these three spirit stones could be used as fertilizers. But overall, wood spirit stones were the most effective, earth spirit stones were second, and water spirit stones were third.
He also tested the metal and fire spirit stones, but they were completely ineffective. After absorbing the spiritual qi of the metal spirit stone, the purple spirit grass quickly withered, and the fire spirit stone directly burned the purple spirit grass into black ashes.
Overall, one Spirit Stone could grow three Purple Spirit Grasses. According to his previous success rate, it was close to forty percent, which meant that after refining pills, according to the price of Qi Gathering Pills, once he sold one spirit stone, he could get four spirit stones in return.
Although the Aura Converging Pills were less effective for cultivators in the middle stage of the Aura Refining realm, they were superior in quantity. With enough medicinal pills, his cultivation speed began to increase exponentially. It was several times faster than when he cultivated by meditating alone. In half a year, he had just entered the fifth stage of Qi Refinement, and now, he had accumulated half of his Qi Refinement.
At this time, Lu Xiaotian, who was dressed in green, had grown a lot taller than before. His body was still slightly thin, and he was not very handsome, but he still had a delicate face. Because he had been alone for a long time, and had experienced life and death tribulations in the past few years, Lu Xiaotian had a cold and distant temperament.
Roar … The leopard's senses were more sensitive than ordinary cultivators, and it quickly noticed the movement outside the courtyard. It was originally lying lazily in the courtyard, basking in the sun, but it suddenly stood up.
There was a knock on the door.
"Is Brother Lu here?" Luo Qing shouted from outside the house.
Hearing the voice, the leopard returned to its original place. In the past half a year, the Luo siblings would occasionally come to the door, and after a few times, the leopard remembered them.
"Hey, the smell of this Qi Gathering Pill is different from usual." Luo Qing walked in and sniffed a few times.
"Why are you here so early today?"
Lu Xiaotian smiled and avoided talking about the pill. Just now, he was lucky and actually refined a high grade Qi Gathering Pill. In the past half a year, he had been refining Qi Gathering Pills nonstop, and the number of times he had refined Qi Gathering Pills could not be compared to the number of times other alchemists added together in a few decades. After all, even if he planted purple spirit grass in the spirit field, he could only harvest it once a year. It was impossible to be like him, who could continuously harvest spirit grass as long as he had spirit stones.
Luo Yuan said, "It's like this, in four months, the major immortal sects will start their annual disciple recruitment. Us Brother Lu and a few other close friends plan to enter the Full Moon Mountain Range to look for some spirit objects. If we are lucky, we can also find items from other sect missions. Brother Lu, your strength is not bad, I want to invite you to form a team. With one more person, we will be safer in the Full Moon Mountain Range."
"Why, is the Full Moon Mountain Range very dangerous?" Lu Xiaotian asked in surprise.
"Brother Lu, Brother Lu may not know, but the Full Moon Mountain Range is not only filled with demon beasts, but also with other cultivators. I have been to the Full Moon Mountain Range several times, and the number of teammates who died in the ambush of other cultivators is more than those who died under the attack of demon beasts. "Luo Yuan said in a deep voice.
Lu Xiaotian was shocked. He had stayed in the small courtyard to refine pills for half a year, and the bloody killings between immortal cultivators had faded a bit.
"Brother Luo, who are the other people you invited? Who is the one with the highest cultivation? "Lu Xiaotian asked and did not directly answer.
"Including us brother and sister, there are five other people, and the one with the highest cultivation is the same as me, at the sixth level of Qi Refining. However, Brother Lu is an extremely brilliant alchemist, if you join our team, Brother Lu will have a certain priority in obtaining the spirit grass. "
