After the sacrifice was completed, Li Xiangnan thought in his heart, and after the body of the Dragon and Tiger Heavenly Heart Furnace trembled slightly, it slowly flew into Li Xiangnan's palm.

It's just that the Tianxin Furnace is very heavy, and it looks a little bulky when it flies, and he can't be as light and elegant as the Yin Evil Gourd, and it feels particularly heavy when he starts it, like a thousand heavy burdens.

Go!

After Li Xiangnan's attention, the Tianxin Furnace flew up, although it was a little slow, but its momentum was strong, and it hit the cave wall at once.

Rumble~!

There was a loud noise, and the cave trembled, and stone chips flew and splattered, and a large pit was smashed into the cave wall, and one of the ears and one foot of the Heavenly Heart Furnace were deeply embedded in the wall, undamaged.

After trying it, seeing this good effect, Li Xiangnan was overjoyed.

After another thought, the Heavenly Heart Furnace broke away from the cave wall, brought out some stone chips and rolled down the cave, trembling and flying back to Li Xiangnan's hand.

Now that his mind can control the furnace of this lower quality magic weapon, Li Xiangnan decided to try to practice the refining of Guyuan Pill.

The Dan furnace was placed on the small stone furnace and began to be quenched and heated with a yang fire, Li Xiangnan uncovered the lid of the Dan furnace, put the well-proportioned materials into it, and then controlled the heat of the yang fire and began to refine.

It's just that this is Li Xiangnan's first time refining pills, and this is not alchemy in the real sense, the first practice, the control of the fire, and the guidance of the medicine are not proficient.

After a while, Li Xiangnan's mind sensed a crackling sound coming from the furnace, obviously because the refining had failed.

When he opened the lower mouth, he saw a pungent smoke coming out of the Dan furnace, gradually turning into a stream of black ash and scattering, and there was not even any medicine residue left.

This is obviously too much, and even the process of drug guidance has failed.

One of the most important aspects of alchemy is the selection of fire, and the other is the ratio of materials, the quality of materials, as well as alchemy skills, medicine guidance, and so on.

It's just that Li Xiangnan is currently a novice, and he has only begun to contact alchemy medicine, and he can only start from the most basic alchemy......

In short, only after the mastery of alchemy has laid a good foundation, and then the study and refining of alchemy will be done, and then the result will be twice the result with half the effort.

This is the same as the process of Li Xiangnan's practice of alchemy, starting from the most basic refining method, mastering the skills and methods, and then gradually practicing to improve the success rate after gaining experience.

Therefore, the failure of the second refining was expected, Li Xiangnan summed up the reasons for the failure, and began to practice for the second time.

However, the difficulty of this alchemy technique is obviously much greater than that of refining the weapon making method and the talisman making technique, just like the problem of liquid fusion after the medicine in the Dan furnace is refined, every detail must be cautious, and the ratio of medicinal liquid ingredients cannot be bad, and if there is a slight mistake, then there is a great possibility of failure.

Even, sometimes, although these processes can be carried out smoothly, due to the influence of many factors in the medicinal properties, the medicinal properties of the drug will change, even if it is successfully refined, it may no longer be a Guyuan pill, and it may also be a fatal **.

Alchemy is the most basic content in the art of alchemy, and it is also a basic lesson that every novice cultivator must learn and master.

After Li Xiangnan first came into contact with alchemy, he was able to have a deeper and intuitive understanding of this subject in the process of actually learning the operation and proficiency of alchemy.

He felt that this course was very professional, and it was even twice as difficult as the basic refining method and the basic talisman making technique.

Especially in the process of refining medicine, even those materials have been proportioned according to the prescription in advance, but if you want to achieve the inherent effect, you must achieve the fusion of medicinal ingredients according to the prescription skillfully, not too much, not too little, but also to master the guidance of the medicine...... and so on, and none of them can be careless.

Because these steps are interlocking, and at the same time, they are more mind-consuming, so we must be careful and cautious, if the refining fails, even if it can barely succeed, it is very likely that the medicinal properties of the refined drugs will change unknown, and it is impossible to become **.

Therefore, the process of refining medicine is more cumbersome and mind-consuming than the basic refining method.

At present, Li Xiangnan has spent a lot of energy to practice, and he has failed seven or eight times in a row, and none of them have succeeded, but he is not discouraged, and he still sums up his experience in failure and continues to practice.

It wasn't until his energy was almost exhausted and his spiritual power and true qi were about to be exhausted that Li Xiangnan insisted on practicing until the tenth time, and finally succeeded once.

A successful experience is not easy to come by.

Li Xiangnan's mood is still peaceful, although many consecutive failures have exhausted him, but with this successful refining, he can get the successful experience summarized from it, which makes him feel refreshed.

With a move in his mind, he took out the pill that had been successfully refined and looked at it.

I saw that the shape of this pill was not too irregular, slightly flattened, the surface luster was also a little dull, and even slightly rough, and it didn't look good, but it smelled like a faint fragrance.

Looking back at the introduction of the characteristics and efficacy of Guyuan Pill in the alchemy technique in the "Kaiwu Collection", judging by the color, smell, medicinal properties and other characteristics of his medicine, the medicine that Li Xiangnan successfully refined this time can be said to barely reach the minimum standard of Guyuan Pill.

In other words, this Guyuan Pill that was successfully refined could only barely wield the seven or eight successful effects of the True Guyuan Pill at most.

With a mouth, Li Xiangnan threw the Guyuan Pill into his mouth and chewed on it like a bean, only to feel that after the medicinal power was waved, a stream of heat quickly began to surge throughout his body, and turned into a stream of blood essence qi that began to moisten his body.

Even, after taking this Guyuan pill, Li Xiangnan felt that his tired body was gradually beginning to recover, and his qi and blood were vigorous, his veins were smooth, and his mechanism and function were also strengthened, and even the feeling of hunger was eliminated a little.

Although it has only seventy or eighty percent efficacy, it cannot achieve the effect of consolidating the foundation and cultivating the yuan for the time being, but its effect of nourishing qi and blood, nourishing and fitness can be well swayed, and there are not too many residual side effects of medicinal properties.

With the experience of successfully refining medicine this time, Li Xiangnan did not continue to practice.

After summarizing and memorizing in detail the many refining failures and the successful experience of this time, he put away the Dan Furnace, sat down cross-legged, and began to cultivate the true qi of the Dantian.

Wait until the true qi is almost restored, then rest and eat, and then continue to practice medicine.
