The next batch of ripening powder has not yet been purified, and the strong chemical fertilizer cannot be made, but for the spiritual herbs and strong chemical fertilizers, it is now possible to spare some time.

Du Fan thought about it like this, so he returned to the hut and took out the small five-element magic trick given by Ye Feng and looked at it.

"The cultivation techniques for improving cultivation are similar to the content of the volume I bought, but in this volume of cheats given to me by Brother Ye, there are several more water attribute spells, but the spells can only be urged by their own mana, and they are useless to me before breaking through to the first level of the Qi Refining Period. Du Fan muttered to himself and sighed, looking very pityful.

"If the qualifications are a little better, it should not be difficult to break through the first layer of the Qi refining period, Ruoxi and Xiaohu have both broken through in a few months, but my qualifications here are ......" Du Fan thought of this, and after being stunned for a moment, he could only smile bitterly.

Du Fan sat on the bed, began to close his eyes and pranayama, and when his body state was adjusted to the best, he began to try to communicate with the aura of heaven and earth for exhalation and absorption, and then open up the meridians.

Time passed, and a month passed.

During this period of time, except for the collection of ripening powder every once in a while, and then made into powerful chemical fertilizers, Du Fan spent all his time in cultivation, but the progress was slow, and there was no sign of improvement in cultivation.

In the middle, he had taken the Qi Refining Pill twice, and under the effect of the medicinal power, although the cultivation progress was much faster than that of meditation and breathing, on the whole, it was still too slow, and if he continued at this rate, if he wanted to break through to the first level of the Qi Refining Period, it would take ten or eight years at the earliest.

"If you take one Qi Refining Pill every day, after a year, how can you forcibly break through to the first level of the Qi Refining Period. Du Fan's eyes flashed, and he couldn't help but think like this, and planned to find a time to go to the Seven Star Business Alliance again, even if he took some risks, he would sell some more spirit herbs in exchange for a large amount of spirit stones, which would be used to support the consumption of pills in the cultivation process.

In fact, in the exercises given by Ye Feng, there is also a way to quickly improve cultivation, that is, the spirit gathering array, this array needs to consume a large number of spirit stones, in the cultivation world, it is also a fairly common small magic circle, with several magic tools as the parts of the magic circle to arrange, after the arrangement is completed, it is also necessary to use eight spirit stones as energy to stimulate this array, this array can gather the spiritual energy of the four directions of heaven and earth in the array, so that the spiritual energy in it is extremely dense, and the person who sits in it to practice, the speed of cultivation can be said to be twice the result with half the effort.

But the consumption of this magic circle is also huge, and the people in the realm of the Qi refining period need to put in eight low-level spirit stones, but the magic circle can only last for about a day, and the spirit stones will be shattered due to the exhaustion of spiritual power, and then they need to put in new spirit stones to continue to maintain the operation of the magic circle, and the consumption of spirit stones brought by this array is not at all something that ordinary Qi refining period people can bear, even in the Empty Mulberry Gate, I am afraid that only those core disciples of the Middle Court can use this method to cultivate.

Du Fan decisively gave up this method, not because he couldn't afford to consume the spirit stone, but because even if the aura concentration was hundreds of times higher and thousands of times higher, surrounding him, with his waste spirit root qualification, it would not be of much help, how much aura he originally absorbed was still how much, and the speed at which he absorbed the aura of heaven and earth would not change with the increase in the concentration of aura around him.

After some thought, Du Fan still felt that it was more reliable to continuously take Qi Refining Pills to increase his cultivation.

"Duvan. ”

A crisp and pleasant woman's voice suddenly came, and when he heard this, he was not surprised, put away his thoughts for the time being, and quickly got up and walked out of the house.

Qin Xiaoran, who was dressed in the clothes of an inner disciple, stood there with a beautiful face and fluttering long hair.

"This is a list of spiritual herbs that Master needs, you can take a look. Qin Xiaoran opened his mouth crisply, and at the same time handed Du Fan a list, his voice was not as indifferent as when they first met, and he didn't know if it was because of what happened when the two met in the alchemy room office last time, or if it had something to do with Ye Feng.

"No problem, Senior Sister Qin, wait a minute. Du Fan glanced at the paper sheet, smiled at the woman, and nodded.

After the half-pillar of incense, Du Fan took out a package and handed it to the other party, which was naturally filled with various spiritual herbs.

Qin Xiaoran let out a wisp of divine thought, and after a brief inspection, he nodded, and patted the storage bag above the slender waist with his bare hand, and a yellow light shot out, and was grabbed by this woman with one hand, and it was a yellow bag, and the previous package containing spiritual herbs disappeared at this time.

"Here, your spirit stone. After the woman threw the yellow bag to Du Fan, she seemed to remember something, her eyebrows furrowed slightly, and she couldn't help but speak again: "It is said that you should not be short of spirit stones now, you can go to the grocery store in the door to buy a storage bag, it will be much more convenient." ”

"Thank you Senior Sister Qin for reminding me, but if I have a storage bag hanging around my waist, wouldn't it be too ostentatious, and anyone who sees it will know that I am not honest on weekdays. Du Fan was stunned when he heard this, and immediately touched his nose and explained embarrassedly.

"Huh...... You're cunning and shrewd, but I don't think about it. Qin Xiaoran smiled and looked at Du Fan, her beautiful eyes flashing with amusement.

Senior Sister Qin teased. Du Fan coughed dryly, and the embarrassment on his face became even stronger.

"I see that you are usually quite honest and honest, but in fact, you put a lot of thought into it. I'm leaving, by the way, there will be a big competition in the door recently, and after the big competition, rewards will naturally be issued, and among these rewards, the proportion of pills is not small, so in the next period of time, Master will prepare a large number of alchemy, you are ready, the next time I come to look for you, I may have to buy a large number of spiritual herbs. ”

Qin Xiaoran made fun of Du Fan again, which made Du Fan embarrassed, and when he was about to leave, he suddenly remembered something, and after telling him again, he left with a smile on his face.

"Dabi?alchemy?" Du Fan was stunned when he heard this, and then his eyes shot out a fine light, and just now, a flash of inspiration appeared in his mind, as if he thought of an important thing, but then he couldn't remember it.

"A very important thing!" After a long time, Du Fan let out a breath, but no matter how he thought about it, there was no trace, and in the end he could only put this matter down first.

Glancing at the bag of spirit stones in his hand, a smile appeared on the corner of his mouth, and when he was about to go back to the house to continue his cultivation, he inadvertently glanced at the medicine garden, and suddenly, his steps paused, his mind buzzed, and the spiritual light just now appeared, as he looked at the spiritual herbs scattered in the medicine garden, he instantly remembered, under the excitement, his hands trembled, so that the bag of spirit stones fell to the ground in an instant, as if unknown.

Although I don't know how the elixir is refined, in the general direction, it must be an elixir made from several kinds of spiritual herbs that go through a series of chemical reactions in the alchemy furnace, disperse and then reorganize, and finally condense. If this is the case, why do you have to refine it into an elixir, as long as you know the ingredients of the elixir and the proportion of each spiritual herb in it, and then take out the essence of various spiritual herbs, and blend them according to this proportion, you can make something with the same effect as the elixir. As he continued to think and talk to himself, Du Fan's eyes burst out from time to time.

"It is said that alchemists are extremely scarce, and there are ranks, for me, becoming an alchemy master, that is basically impossible, even if it is an alchemy master, according to others, alchemy also has a success rate, and no matter how high-grade the elixir is, there are certain side effects. By means of biological science, it should not be difficult for me to make a kind of pill-like thing without side effects, if the same kind of thing succeeds once, it will definitely succeed again and again in the future, and it is much easier than alchemy, as long as the ingredients are complete, it can be made at any time and can also be mass-produced, and there will be no success rate problem.

The most important thing is that the things made by this method are, theoretically speaking, much stronger than the medicinal properties of the pill. ”

The light in Du Fan's eyes became brighter and brighter, his body trembled, and he seemed to be unable to restrain himself from excitement.

"To put it bluntly, the pill is the medicine, and the medicine is not necessarily solid!"

Du Fan became more and more sure of his idea, and he believed that if he could put this idea and hypothesis into practice, he had a high probability of success.

"Even if it is a spiritual herb, there may not be essence everywhere in it, I want to extract the essence of them, and even change its internal structure, and this process, I need a catalyst, refining the ripening powder produced by gluttonous hair hair, is the most suitable catalyst!

Du Fan figured out all the questions, the firmness and perseverance in his eyes were already strong to the extreme, and there was excitement, at this time, the only problem for him was Dan Fang.

Thinking of Danfang, he couldn't help but fall into contemplation again, and after a while, his thoughts gradually became clearer.

"To obtain the Dan Fang, there are only three choices, one is to try your luck at the Menzhong Grocery Store or the Alchemy Room Office, the second is to go to the Sangcheng Xiuzhen Shop to buy it, and the third is to spend some money to exchange it for a copy from an alchemist in the Gate. ”

The last choice, Du Fan, just thought about it for a moment and put it behind, this is simply impossible, the alchemist has a special status, how can he see it when he says it, let alone negotiate the conditions with his identity. And the second one has no problem, it can basically be bought, but he is now refining ripening powder day and night, plus there are often small businesses coming to his door, so it is difficult to get out.

After a long period of silence, he could only try his luck at the grocery room and the alchemy room office in the door.

After making up his mind, Du Fan took a deep breath, prepared a small bag of spirit stones, and walked out of the spirit garden in one step.
