After Meng Fan returned to the sword shrine, he immediately took out the small porcelain bottle containing the snake gall. He carefully uncorked the bottle and immediately smelled a fishy odor.

According to the original record, this snake gallbladder can not only enhance internal strength, but also enhance qi and blood, and it is extremely wonderful.

However, the snake gall in Meng Fan's hand is really not small, and it is impossible to swallow it, but according to the records in the book, this snake gall is extremely bitter, and Meng Fan does not dare to bite it and try it.

Fortunately, Meng Fan's more than ten years of Taoist collection has not been read in vain, when he first flipped through the scriptures, he had read a scripture on alchemy.

This scripture not only records the method of alchemy, but also records seven or eight kinds of pills, among which there are two elixirs with snake gallbladder as the main medicine, one is Longli Pill and the other is Bear Snake Pill.

Longli Dan is mainly made of snake gallbladder as the main medicine, with 100-year-old ginseng and other herbs. The effect of this pill is similar to that of the Bodhisattva snake gall bladder, which can increase internal strength and qi and blood at the same time.

The effect of the bear snake pill is completely different from that of the Longli Pill, which uses bear bile and snake gall bladder as the main medicine, and then combines it with Tian Qi and other herbs, its main effect is to heal injuries, and at the same time can quickly restore internal strength.

Meng Fan was not worried that the elixir refined would reduce the effectiveness of the snake gall bladder, in fact, this was simply impossible. Why did the ancient Taoist priests invent alchemy, wasn't it just to better absorb the effects of herbs?

Refining snake gall into a dragon power pill can not only retain its medicinal effect, but also make its medicinal power more mild and easier for people to absorb and use. Also, fresh snake gall can't be kept for long, but pills can last for years, even decades.

Of course, for Meng Fan, the most important thing is that the taste has improved!

Since it is necessary to refine the Dan, the Dan furnace must be indispensable. Fortunately, Meng Fan had considered this matter before he came to Xiangyang, and when he left Zhongnan Mountain before, he walked a good alchemy furnace in a Taoist temple, and right now, the Dan furnace was in his Xiaoding.

At that moment, Meng Fan put away the small porcelain vase, sat down cross-legged at the same time, and his mind quickly entered the space inside the ding. Because of the difference in the speed of time, more than a hundred years have passed in Xiaodingzhong, and the vast land in the Dingzhong has been covered with sporadic green, and there is no longer the original dead silence.

In the space inside the Ding, the body formed by Meng Fan's consciousness soon appeared on the top of a mountain. This mountain is extremely high, the top is flat like a playground, and it is a fixed place for Meng Fan to practice swords and read scriptures in the past.

In the corner of this hilltop platform, there is also a simple stone house. The stone house is not large, and it is used by Meng Fan to store books.

In front of the stone house is a Dan furnace the size of a water tank. The whole body of the Dan furnace is purple-red, it seems that the year is not short, if it is close, you can faintly smell a medicinal fragrance.

After Meng Fan came to the top of the mountain, he immediately entered the stone house, and after a while, he walked out with a book.

This book is the book that records alchemy, Meng Fan directly turned to the page that recorded the Longli Dan Dan Fang, and then studied it carefully.

In fact, this alchemy is not as magical as described in the Xianxia novels in the previous life, it is not so much alchemy as it is boiling medicine, at most it is just that the method of boiling medicine is a little special.

Meng Fan had studied this alchemy before, and there were two main points to sum up, one was to put the herbs in time according to the order recorded in the Dan Fang, and the other was to control the heat.

If you do these two things, you can boil those herbs into pure medicinal powder or ointment, and then mix them with honey to make pills, instead of directly refining them into pills as the legend says.

The auxiliary drugs needed by Longli Dan are planted in the space of Ding, and the years are more than 100 years old, which basically meet the requirements, as for the snake gallbladder required for the main medicine, Meng Fan does not dare to directly use the snake gallbladder of the Bodhisattva.

Although Meng Fan knew alchemy, he had never tried it himself, the snake gall of the Bodhisattva Qu Snake was too precious, and if the refining failed, he would not have to die of distress.

He thought in his heart, anyway, there are enough auxiliary medicines in the space inside the Ding, and there are also a lot of poisonous snakes for a hundred years, so before using the snake gall bladder of the Bodhisattva snake, it is better to use the snake gall of these ordinary poisonous snakes to increase his experience.

Thinking of this, Meng Fan quickly disappeared on the platform at the top of the mountain, and when he came back, there was already a bamboo basket in his hand, and the basket contained a large number of ginseng and other herbs, as well as more than a dozen small porcelain bottles, which contained the snake gall of various poisonous snakes, including golden snakes, silver snakes, and five-step snakes, and so on.

In the following days, Meng Fan devoted himself to alchemy, while Li Dayan and the others followed his instructions to specifically capture those Bodhisattva snakes that were not old and whose bodies were not thicker than the handle of the axe.

These Bodhisattva snakes were all collected by Meng Fan into the space inside the Ding, and at the same time, he also deliberately mobilized the mountains in the interior of the Ding, creating a canyon similar to the living environment of the Bodhisattva snakes, and raising these Bodhisattva snakes in it.

......

Time flies quickly, and in a blink of an eye, more than half a month has passed.

During this period of time, Meng Fan had refined the Dragon Power Pill regardless of the cost, and his alchemy experience had improved rapidly, and now, he could already guarantee a ninety percent success rate.

The reason why this is so is also due to Xiao Ding, in the space inside the Ding, Meng Fan's control of the heat will hardly make the slightest mistake. In this way, it is difficult not to succeed.

At the same time, there are fewer and fewer young Bodhisattva snakes in the mountains and forests, and in recent days, Li Dayan and others have not gained anything, plus they have been away from home for a long time, and they have already put forward a request to return to the village.

In this regard, Meng Fan did not refuse. Just yesterday, after paying three hundred taels of silver, he sent Li Dayan and the others home.

Meng Fan was not worried about Li Dayan and the others revealing the news here, firstly, the other party did not know the use of his snake gall bladder at all, and secondly, after he left, there were probably very few Bodhisattva snakes here.

In the early morning of this day, after Meng Fan got off the sword mound, he carried the Qingfeng Sword into the strange mountain forest. He had been gone for a whole day, and he didn't return to the Sword Demon Valley until sunset.

On this trip, Meng Fan hunted the older Bodhisattva snakes and obtained a total of more than 20 snake galls. After returning to the Sword Shrine, he immediately entered the space inside the Ding and began to refine the Dragon Power Pill.

An hour later, Meng Fan withdrew from the space in the Ding with a tired mind. By this time, night had fallen, but the darkness could not drown out the joy in his eyes.

In this alchemy, Meng Fan used up all the Bodhisattva Qu snake gall bladders, and obtained a total of more than 100 dragon power pills. With so many pills, it was enough to raise his internal strength to the realm of acquired perfection.

At that moment, Meng Fan took out a pill of Longli Pill and swallowed it decisively.

Soon after the pill entered his abdomen, Meng Fan felt a burst of warmth coming, he didn't dare to slack off, and hurriedly operated the true qi in the dantian according to the Jade Emperor's fist heart method, refining the medicinal power of the dragon power pill little by little.

Time passed little by little, and it was not until dawn that Meng Fan completely absorbed the medicinal power of the Dragon Power Pill. He slowly finished his work, feeling the Jade Emperor's true qi that had obviously increased in the dantian, and his heart was suddenly overjoyed.
