The preparation materials are complete, but if you want to really start alchemy, it is not so simple.

Li Bufan flipped through the Dan Dao Ten Texts that he got in his hand several times, but he didn't understand the alchemy techniques in it and the outline of alchemy, as if he was reading a book from heaven, jerky and difficult to understand, even more difficult than when he practiced on weekdays, or even what new techniques he practiced, it is no wonder that there are very few people who have achieved success in alchemy.

Li Bufan didn't ask for a certain height in this aspect, he just wanted to be able to refine some pills that suited him, but it was just such a simple idea, but after going deeper, he found that it was simply a fool's dream, and this was not an introductory knowledge, which already made Li Bufan feel his scalp tingle.

The ten texts of Dan Dao not only describe some Dan prescriptions and techniques, but also some fundamentals of alchemy, and some pharmacological knowledge, which is not a simple matter to memorize all of them.

He focused all his energy on this as much as possible, although it was difficult, it was better than Hua Lingshi buying the pill by himself.

In the ten texts of Dandao, there are several kinds of pills recorded, and there are two kinds of pills that Li Bufan can use at this time, one is the Qingxu Powder that is urgently needed, and the other is a type of pill called Fengling.

Qingxu Scatter is very important to Li Bufan now, and the improvement of the realm depends on it.

As for the Wind Spirit Pill, although Li Bufan had never heard of it, according to the introduction of the Dan Dao Ten Texts above, after taking it, it seems that it can improve the mobility of the cultivator's body and greatly increase the speed of the user, which is also a rare elixir.

Xu is extremely effective, and the refining method of the Wind Spirit Pill is even more complicated than that of the Clear Void.

As for the herbs needed to refine the Wind Spirit Pill, Li Bufan had never heard of it. Obviously, it is not something that a person of Li Bufan's level can refine.

So now Li Bufan can only put aside the other Dan prescriptions and concentrate on studying the Qingxu San.

Qingxu San requires a total of seven kinds of medicinal materials, two of which are named: Kong Qing and Angelica Angelica, these two medicinal materials are also very common in the secular world, but the remaining five are only found in the cultivation realm.

The most important thing is the nightshade that Li Bufan picked before!

The nightshade is used as a medicine in the whole herb, condensing the medicinal power of all the herbs, plus its own special effect, supplemented by the method of refining, it can be refined to clear the void.

Li Bufan can be regarded as reacting at this time, no wonder the price of Qingxu San on the market has been rising during this time, and now it has risen to one of five spirit stones, most of which is because of the spread of the Dongshan Demon Beast before, no one dared to go there to pick the mountain nightshade, which led to the decrease in the stock of the sect's mountain nightshade, and the price of this Qingxu powder naturally rose.

Thinking about it this way, the culprit who caused the price of this pill to skyrocket was Li Bufan himself.

Thinking of this, Li Bufan couldn't help but feel a little embarrassed, he had complained about this unknown price increase before, and even secretly cursed the initiator of everything, but he didn't expect it to be scolded on his head.

But no matter what he said now, it was useless, Li Bufan took out the previous bag of medicinal herbs from the storage bag, and a burst of joy flashed in his eyes, and he felt very glad that he had not handed over all the nightshade at the beginning.

Thinking about it, he patted the bulging bag, and then put the medicine bag back again.

Li Bufan stayed in the room for a few days in a row, wanting to familiarize himself with the refining method of Qingxuan San, but in the end he overestimated himself, and in the past few days, he only understood a little bit about the pharmacology and medicinal properties of the seven flavor medicinal materials, and he didn't know how long it would take before the official start of alchemy.

For Li Bufan, what he can rely on now is the "Ten Texts of Dan Dao" in his hand, Li Bufan can only continue to explore slowly by himself, there is no other way, as Feng Jing said, alchemy is not so simple.

Time passed day by day, and Li Bufan stayed in the room all day to study "Dandao Ten Texts".

Although Li Bufan still doesn't know if he can disperse the Qing Void and successfully refine it, but since this matter has already been resolved, he has to work hard to do it, no matter what the result is, the path of cultivation is in his own hands.

Time flies by like water, and in the blink of an eye, it is three months. In the past three months, in addition to practicing the method of alchemy, Li Bufan also went to Yangsheng Street for a few laps and bought several other medicinal materials with the remaining spirit stones, but he didn't expect that these medicinal materials were not cheap, and it took nearly two spirit stones to refine a Qingxuan San, and he thought that he still needed to practice, so he would definitely not be able to refine it in a short time, so he simply gritted his teeth and bought enough to refine fifty Qingxu San, this time, it really emptied Li Bufan's pocket, and he could only hope that he would not use all the fifty Qingxu Sans to practice, otherwise you will really go bankrupt.

Nearly half a year has passed since he began to study alchemy.

His insights in this area have also deepened, and it is time to start getting started, and he can't keep talking about the army, not to mention that his cultivation has been delayed for too long, and he can't delay it any longer.

After he packed up his things, he asked all the way where there was a ground fire in the Yishan Sect, but after asking a few people in a row, they all said that they had never heard of any earth fire.

Li Bufan couldn't help but wonder, if there was no earth fire in the sect, then how could he refine the elixir and magic weapons?

He could only hold on to a glimmer of hope and continue to ask others.

finally paid off, and when I asked a senior brother, I got the answer.

Yishan Sect does have an earth fire, which is also an important place for the sect, and the usual pills and magic weapons come from there, but because the cultivation of the two realms of pills and weapons is extremely difficult, few cultivators will dabble in it, and only some disciples know where the earth fire is.

Li Bufan thanked the senior brother, and then walked in the direction he pointed, and there were fewer and fewer other disciples on the road, and it could be seen that even on this road, few people would walk, let alone know where the earth fire was.

It is also an extremely high mountain road, and the distance is not close, not to mention dozens of zhang away.

After walking for a while, he finally arrived, but the scene in front of him made Li Bufan look amazing.

The range of thirty or forty zhang in front of Li Bufan was flattened by some special means, and there was not a single weed.

At the end of the clearing, a heaven-like giant gorge stood in it, and in the middle was a bottomless crack, which was obviously just a canyon, but it brought Li Bufan a huge shock.

As soon as Li Bufan took a step forward, he already felt several vigilant eyes looking at him in the dark several times, but it seemed to be looking at Li Bufan's mana, so he quickly reined in. But even so, Li Bufan was secretly surprised.

These people were able to peek at him from such a distance, and they couldn't let him sense the location, which means that the other party either has a good magic weapon that can hide his body, or his realm is far from being comparable to himself, thinking of this, Li Bufan also broke out in a cold sweat.

Although they may not necessarily make a move on Li Bufan for no reason, in the face of so many strong people, it still makes Li Bufan more cautious.

Due to the retraction of his gaze, the pressure on Li Bufan's body also relaxed a lot, he exhaled, strengthened his courage, and continued to walk inside.

After a sudden wave of spatial fluctuations, a blue wall of light appeared in front of Li Bufan in front of him, and then two disciples dressed in gray clothes also appeared in the wall of light.

"Stop! Who are you, the sect is important, and you are not allowed to enter and exit at will! A red-clothed disciple said coldly.

"Disciple Li Bufan, I came today to borrow the sect's earth fire alchemy pill to use, and I ...... it."

"Okay, okay, since it's alchemy, let's hurry up and hand over the spirit stone and go in, we don't have time to listen to your nonsense."

Another man in gray interrupted Li Bufan, sounding very impatient.

Li Bufan was not polite to the man, but he was not angry, he just wanted to go in quickly.

Then after Li Bufan handed over enough spirit stones for ten days of alchemy, the two gray-clothed men formed a method at the same time to break the light wall, and as a result, the light wall expanded into a passage half a zhang wide, just enough to accommodate one person to enter and exit.

Li Bufan hesitated when he saw this, and immediately his figure flashed, and the person had already entered it.

After another wave of spatial fluctuations, the three of them had already reached the depths of the canyon. Several stone chambers have been artificially carved out around it, emitting a faint red light, and even the temperature is much higher than the outside.

A gray-clothed man sensed Li Bufan's body with his divine sense, and did not find anything dangerous, so he put a mark on his left hand.

"This mark will tell you when to leave, and it can also open the teleportation circle for you again, and after ten days, if you don't make up the spirit stone, it will also force you to teleport away."

"Thank you, senior brother, for telling me." Li Bufan retracted his gaze and returned to the Tao very respectfully, hoping to leave a good impression on the two of them, after all, they will come here often in the future.

But the two don't seem to pay much attention to Li Bufan, there are too many gaps between them, and there won't be too many intersections in the future.

They took Li Bufan to one of the stone rooms and turned to leave.

Li Bufan looked at the environment in the house with some curiosity, it was very dim, if it wasn't for a few stone lamps, it would be like covering Li Bufan's eyes with a black cloth.

In addition to the stone lamp, there is a stone bed, a stone table, a stone frame, and a stone bench, and everything that can be seen is made of stone. Li Bufan looked around, what he came for this time was not these, but the fire of the lungs in the land.

Finally, his gaze focused on the ground in the center of the stone chamber, on a Taiji stone trough.

Li Bufan stepped forward quickly, leaned down, and carefully examined the novelty in front of him.
