After settling down, Lu Xiaotian took out the Dan furnace again, cleaned the impurities and wastes in the tripod, and raised the fire to refine Dan again.

The most difficult fire for alchemy and the opening time are extremely difficult to grasp. It usually takes nearly two hours to refine Qi gathering pill. Lu Xiaotian must always pay attention to the size of fire. When the fire is too large, remove a little spiritual wood carbon and add carbon when the fire is small.

However, these two points are all mastered by the experience of alchemy people. It is not easy to refine pills with only one pill.

Even primary alchemists are very popular in Wangyue City, because alchemy is not only difficult, but also a profession that consumes spirit stones. For those who have just learned alchemy, the rate of alchemy is often ridiculously low, often several or even more than a dozen heats may not succeed once. To improve the yield of Dan requires long-term practice and experience accumulation.

Ordinary casual repair is simply unable to bear such a heavy burden in the early stage. Most of the alchemists in Wangyue city are trained by the families who control each Dan workshop with family resources.

The trained alchemists need to work for the danfang of each family. Usually, the pills sold to the outside world are inferior pills, while the middle and even top-grade pills with better quality are taken by talented people in the Xiuxian family, or appear in the auction house and sell at an amazing price. Therefore, the strength of people from the Xiuxian family is often stronger than ordinary casual cultivation.

In addition to the time of daily cultivation, Lu Xiaotian stayed in the yard for nearly ten days to practice elixir. Seventeen heats of elixir were continuously refined and discarded, and the rest of the holy stones were almost used. Such a high failure rate made him a little discouraged. If the purple spirit grass could not be cultivated in the space within the border, this intensive elixir refining would not have been possible.

The value of 17 purple spirit herbs alone is as high as nearly 40 spirit stones in Wangyue city. If you count the auxiliary drugs, the spirit stones wasted by Lu Xiaotian in recent ten days are very amazing for a friar in the period of Qi refining.

However, through so many failures, Lu Xiaotian summarized a set of methods for refining Juqi pill. I also have some experience on the heat and opening time. Lu Xiaotian is looking at the hot carbon fire under the tripod.

At this time, he did not take out the spirit wood carbon when the carbon fire was too large, as he had just started alchemy. His previous experience of failure gave him a rough idea of how much firepower needed to be added and how much spiritual charcoal. This is the experience gained by practicing Danshi for a long time.

Nearly two hours later, the familiar fragrance came again. Lu Xiaotian was worried. If he failed again this time, he could only sell the remaining 20 talismans to continue alchemy.

Concentrate, calm down and turn on the stove!

As he opened the lid of the tripod, a warm and familiar fragrance of pills came to his nostrils. I saw two milky yellow pills lying quietly in the small tripod, one of which had a particularly strong fragrance, and there were two small Dan lines on the milky yellow surface.

"Unexpectedly, a middle-grade Qi gathering pill was refined!" Lu Xiaotian was surprised and inexplicable. After working hard for more than ten days, he finally got a reward. This kind of reward after going through hardships is far more meaningful than two pills.

After the heat on the surface of the two round and full elixirs dissipated, Lu Xiaotian put them into vials respectively.

We should take advantage of the heat to forge iron. Now we have successfully refined a furnace of Juqi pill. We will refine it a few more times today.

There were enough seeds left in his hand. Lu Xiaotian refined seven times in succession and consumed all the purple spirit grass in the enchantment. He succeeded three times. There was only one pill, not two as before.

However, he was also quite satisfied with this result. Even some experienced alchemists of wangyuecheng family who have decades of experience in alchemy have succeeded three to four times in ten times, which is a very good achievement.

Alchemy is a skill that pays great attention to the realm, and the fire control and furnace opening are not invariable. Different purple spirit grass has different growth degree and state.

A wise alchemist will predict what kind of heat will be used for the spirit grass in his opponent. There may also be errors in this judgment, so the alchemist will slightly adjust the firepower and discharge time according to the changes in the refining process. However, no matter how powerful an Alchemist is, he can't guarantee that his judgment is 100% correct. A slight difference in the middle will lead to the scrapping of this furnace of pills.

Therefore, experienced alchemists can only maintain a certain success rate.

The reason why Lu Xiaotian can achieve such a high yield in such a short time is in addition to the improvement of his alchemy skills. More importantly, he has refined the same pill for so many times in a row, which other alchemists do not have. In addition, the purple spirit grass growing in the enchantment has not been disturbed by external conditions such as wind and rain, and its growth is relatively consistent. This also increased his Dan production rate.

After refining the last purple spirit grass, Lu Xiaotian put away the tripod with satisfaction. Take out the Chinese medicine Juqi pill. A good pill should be left for yourself. It's time to try the pill.

Lu Xiaotian directly sat on the stone chair in the courtyard and took the middle-grade Juqi pill. The Juqi pill slowly melted in his body and turned into a gentle heat flow to swim around in his limbs and bones.

In the past, it took nearly six hours to refine the medicine power of Qi gathering pill, but now it takes less than two hours to refine five layers of Qi.

The aura that cannot be contained in the meridians still appears in the boundary. After absorbing the medicine in the meridians, Lu Xiaotian's yuan God chased the vitality in the end boundary. Then sprinkle the seeds of purple spirit grass, grind a stone into powder and sprinkle it on the soil next to the seeds of purple spirit grass.

In the previous alchemy, when the purple spirit grass ran out, he was anxious to jump when he cultivated it, because the aura escaping in the air floated around, and it was difficult to float directly to the seeds of the purple spirit grass and be absorbed by it. Later, he was forced to use the spirit stones, and he found that he could control these spirit stones with his mind and crush them.

When using spirit stones, he also pays attention to them. After all, he has five kinds of spirit stones: gold, wood, water, fire and earth. Only the rare ice wind thunder doesn't have it on hand. Water is the source of life, but it should not be used too much. Otherwise, excessive soil warmth is not conducive to the growth of purple grass.

Earth Spirit stone can enhance the spiritual power of the land. The spirit stone of the wood system is also the undergraduate of purple spirit grass. You can use these three kinds of spirit stones as fertilizer. However, on the whole, the wood system corresponding to purple spirit grass has the best effect, followed by Earth Spirit stone and water spirit stone again.

He also tested the gold system and fire system. It didn't work at all. After absorbing the aura of jinlingshi, the purple spirit grass withered rapidly, and the fire spirit stone burned the purple spirit grass directly into black ash.

In general, three purple spirit grasses can be cultivated from one spirit stone. According to his previous success rate, it has been close to 40%, that is to say, according to the price of Qi gathering pill, once sold, a spirit stone can get four returns.

Although the effect of Juqi pill was worse for the friars in the middle of Qi refining, the victory was the large amount. After having enough pills, his cultivation speed began to rise sharply, which was several times faster than that of sitting alone. Within half a year, it had just entered the fifth layer of gas refining. At this time, the energy accumulated in the fifth layer of gas refining has nearly reached half.

At this time, Lu Xiaotian in blue has grown a lot taller than the original. He is still a little thin and not very handsome, but he also has a somewhat beautiful face. Because he has been alone for a long time and has experienced life and death hardships in recent years, Lu Xiaotian has more cold and distant temperament.

Roar... The leopard's sense is more sensitive than that of an ordinary monk. He soon noticed the change outside the yard. He suddenly stood up when he was lying lazily in the sun in the yard.

There was a bang on the door.

"Is brother Lu there?" Luo qingjiao shouted outside.

Hearing the voice of someone, the leopard leaned back to the original place. In the past six months, the Luo brothers and sisters have come to jump the door from time to time. Once or twice, the leopard also remembered them.

"Eh, the smell of Juqi pill is not the same as usual." Luo Qing sniffed hard when he entered the door.

"Why did you come so early today?"

Lu Xiaotian smiled and avoided talking about the pill. Just now he was lucky to refine a top-grade Juqi pill. He has been refining Juqi pill for half a year. I'm afraid the number of times he opened the furnace to refine pills can't be compared with that of other alchemists for decades. After all, even if purple spirit grass is planted in the spirit field, it can only be harvested once a year. It is impossible for him to harvest spiritual grass as long as there is a spiritual stone.

Luo Yuan said, "Well, in another four months, the major immortal sects will start to recruit disciples once a year. Our brothers and sisters and several other familiar friends plan to go into the moon watching mountain to find some spirit objects. If we are lucky, we can also meet items in other sects' tasks. Brother Lu is very strong. I want to invite brother Lu to form a team with one more person. We will be safe in the moon watching mountain One point. "

"Why, is it dangerous in the moon watching mountains?" Lu Xiaotian said in surprise.

"Brother Lu doesn't know. There are not only monsters running rampant in the moon watching mountain, but also other friars. I've been to the moon watching mountain several times. More teammates died in the ambush of other friars than in the attack of monsters." Luo Yuan said in a deep voice.

Lu Xiaotian was shocked. He spent half a year refining pills in the courtyard, but he was a little indifferent to the bloody killing among the immortals.

"Who else are there among the people invited by brother Luo? Who has the highest cultivation?" Lu Xiaotian asked without directly agreeing.

"Plus our brothers and sisters, there are five people together. The one with the highest cultivation is the sixth level of Qi refining, just like me. However, brother Lu is a very clever alchemist. If you join our team, brother Lu has a certain priority in the spirit grass you get at that time."

Luo Qing said expectantly that in the past six months, they have also had some understanding of Lu Xiaotian. They can rent such a large yard and complete daily cultivation by Alchemy alone. In their eyes, it is quite powerful.
