Seeing that Lei Xiaotian had broken through, Hu Jiao'er and Nangong Ling immediately ran to the secret room where Lei Xiaotian was retreating, but Lei Xiaotian said that he would continue to retreat for a few days and try to refine the elixir. As early as when Nangong Ling and Lei Xiaotian fell into the cemetery of the Heavenly Machine Law God, she already knew that Lei Xiaotian was not only a refiner but also an alchemist, while Hu Jiao'er only knew that Lei Xiaotian was a demon martial arts dual cultivator and a refiner.

Hearing Lei Xiaotian say that he was going to retreat and refine medicine, Hu Jiao'er knew that Lei Xiaotian was still an alchemist, and then Hu Jiao'er had a feeling that God was too unfair, and now there were still more than 20 days before their wedding, since Lei Xiaotian wanted to refine medicine, Hu Jiao'er and Nangong Ling naturally would not stop Lei Xiaotian.

Then they ran to the exit of the secret land again and gave the Thunder Thunder Heaven Protector. After Nangong Ling and Hu Jiao'er left, Lei Xiaotian took out the Divine Dragon Ding and placed it in the secret room, and then first took out a Heavenly Spirit Holy Fruit and put it on the table in the secret room, and then took out other auxiliary materials that had already been prepared and put them on the table in turn.

To refine the Heavenly Spirit Holy Pill, in addition to the main material Heavenly Spirit Holy Fruit, dozens of precious medicinal materials are also needed, among which several kinds of elixirs such as Tongmai Grass and Millennium Xuanchu, Tongtian Youju, Purple Blood Lingzhi, Dragon Fruit, and Ice Crystal can also be regarded as genius treasures. Fortunately, Lei Xiaotian got a lot of elixirs in the forbidden land of the gods this time, and all of these dozens of medicinal materials are available, plus the collection of the Heavenly Wolf Gate over the years, as well as the collection of the Lei family in the space ring that Lei Xiaotian's grandfather gave to Lei Xiaotian, it can also match these precious auxiliary materials.

After putting dozens of auxiliary materials and Heavenly Spirit Holy Fruit in order, Lei Xiaotian took out the prescription again, determined the materials according to the prescription, and then carefully studied the unilateral prescription again, and then simulated the refining process in his mind according to the unilateral method, and after making sure that there were no loopholes, Lei Xiaotian sat cross-legged and began to pranayama.

After all, Lei Xiaotian had just broken through, and if he started refining medicine directly, it would definitely be a brainless approach, and this meditation Lei Xiaotian sat directly for a whole day, which was longer than the time it took him to break through.

After Lei Xiaotian opened his eyes again, he could clearly feel that Lei Xiaotian's eyes were very calm at this time, and his breath was not exposed at all, and the whole person seemed to be integrated into the whole world, which showed that Lei Xiaotian had adjusted his state.

The unilateral side of this Heavenly Spirit Holy Pill was also found by Lei Xiaotian from the Heavenly Machine Treasure Record left by the Heavenly Machine Law God, but Lei Xiaotian knew that this Heavenly Spirit Holy Pill was not created by the Heavenly Machine Law God, because Lei Xiaotian knew that in the Southern Wilderness Continent, there were many alchemists who knew the refining method of the Heavenly Spirit Holy Pill, but because the materials for refining him were too precious, especially his main material, the Heavenly Spirit Holy Fruit, almost no one had ever heard of it in the Southern Wilderness Continent, so although this Heavenly Spirit Holy Fruit was only an eight-rank peak pill, because of its effect against the sky, coupled with the fact that there was almost no Heavenly Spirit Holy Fruit, its value was higher than that of the ordinary Nine Rank Pill。 Of course, this is only his price, but even if anyone really has a Heavenly Spirit Saint Pill, they will definitely not take it out and buy it.

When Lei Xiaotian adjusted his own state, Lei Xiaotian's heart moved, and the lid of the Shenlong Ding automatically opened, the Shenlong Ding was not an ordinary alchemy tripod, he was Lei Xiaotian's cheap master, the treasure left by the Heavenly Machine Law God to Lei Xiaotian, the Shenlong Ding itself was originally a ground-level spiritual weapon, and it could naturally be automatically switched on and off with the master's mind.

After opening the lid of the Shenlong Ding, Lei Xiaotian began to use fire magic to stir up the flames in the Shenlong Ding, and after controlling the temperature, Lei Xiaotian began to follow the unilateral instructions to put the Tongmai Grass in the Ding, and after the Tongmai Grass entered the Ding, it was immediately wrapped in the flames controlled by Lei Xiaotian, and under the incineration of the flames, the impurities in the psychic grass immediately turned into smoke and floated out of the Shenlong Ding.

Next, Lei Xiaotian began to refine the auxiliary materials one by one in order, and it took more than three hours, dozens of auxiliary materials were all refined, and dozens of auxiliary materials were all turned into medicinal liquids, and in the flame package of Lei Xiaotian, they stayed in the Ding one by one.

Then Lei Xiaotian closed his eyes again, and raised his mind for a while, about half a pillar of incense, Lei Xiaotian opened his eyes, and then Lei Xiaotian did not hesitate to put the most precious of the materials for refining this time, and it was also the main material of this Heavenly Spirit Holy Pill, the Heavenly Spirit Holy Fruit, into the Divine Dragon Ding.

Lei Xiaotian carefully burned the Heavenly Spirit Holy Fruit with flames, and of course, soon the Heavenly Spirit Holy Fruit was refined by Lei Xiaotian into a red medicinal liquid, flowing in the flames. The first step of refining this medicine is to refine medicinal materials, no matter how many pills are refined, so this step is not difficult for Lei Xiaotian.

But then, it is time to melt the medicine in the most likely step to fail when refining the medicine, and there is not a weak energy in all kinds of medicinal liquids, especially in the auxiliary materials of this Heavenly Spirit Saint Pill, there are dragon fruit and ice crystals, which contain two kinds of energy, one yin and one yang, so it is even more difficult when fused.

After all the materials were refined, Lei Xiaotian rested again, and then began to fuse the medicinal liquid, according to the order, Lei Xiaotian began to fuse these medicinal liquids into the medicinal liquid of the Heavenly Spirit Holy Fruit one after another, of course, the more difficult it was to fuse later, and gradually as the medicinal liquid fused one by one, sweat began to appear on Lei Xiaotian's head.

Slowly, sweat flowed from Lei Xiaotian's back, and it took about eight more hours, and finally all the medicinal liquid was fused into the spiritual liquid of the Heavenly Spirit Holy Fruit by Lei Xiaotian, and then Lei Xiaotian breathed a sigh of relief.

Refining the elixir, there are two difficulties, one is the melting medicine, and the other is the final Cheng Dan, and now Lei Xiaotian has completed more than half of the procedures and overcome a difficulty, although in the final fusion of the ice crystal, due to the conflict between the ice crystal and the dragon fruit, the fusion almost collapsed, but in the end, it was successfully completed with Lei Xiaotian's efforts.

Then, Lei Xiaotian lowered the temperature of the flame, began to use slow fire to warm the medicinal liquid, and at the same time began to recover his already exhausted soul power, about three hours passed, the medicinal liquid in the Shenlong Ding had become viscous, and obviously shrunk a lot, at this time Lei Xiaotian's soul power had basically recovered.

Then, Lei Xiaotian divided these elixirs according to the amount of medicine, originally according to the single party, these elixirs should be able to be divided into at least five groups of liquids, but I don't know why, the liquid medicine refined by Lei Xiaotian is only enough to divide into four groups, it may be because during the refining, due to the fact that the heat was not well controlled, many of the elixirs were wasted.
