The seven treasures of incense in the "Incense Record" are seven peerless elixirs named after wind, fire, thunder, electricity, fog, clouds, and ice, and these seven elixirs are all heaven-level elixirs, and the difficulty of refining them is also based on the order of these seven words. When the Burning Sin was at its peak, he was able to use the Forgetful Life Furnace to refine five kinds of pills at the same time, although there were only three Heavenly Rank Spirit Pills among these five pills, he was already a Dan Dao Sage who shocked the world. Ling Yu Dan's Dao cultivation was still shallow, so he could only refine the most easily turned pill among the Seven Treasures of Incense, the Ice Chalcedony Jade Dew Pill. But even if the Ice Chalcedony Jade Dew Pill was the last elixir among the Seven Treasures of Incense, it was not so easy to become a pill. The "Incense Burning Record" said that if you want to refine the Ice Chalcedony Jade Dew Pill, the alchemist's cultivation must at least be in the Supreme Realm. And Ling Yu, as a cultivator who asked about the state of mind, forcibly refined the Seven Treasures of Incense, it can be said that a newborn calf is not afraid of tigers.

When everything was ready, Ling Yu sacrificed the Forgotten Life Furnace, he took out three sticks of incense from his arms, and after he lit the incense, he inserted them in front of the Forgotten Life Furnace. Then, Ling Yu bowed respectfully three times to the three incense sticks and the Forgotten Life Furnace. Burning Sin had told him that alchemy was a competition with the Heavenly Dao for creation, so he had to have a heart of awe. After performing the Heavenly Worship Ceremony, Ling Yu put the twenty-seven herbs needed to refine the Ice Chalcedony Jade Dew Pill into the Forgetfulness Furnace in order. Ling Yu took out a palm-sized small tripod from the realm spirit ring, this small tripod was black all over, it was not an immortal-level treasure, but a very simple container, what Ling Yu really needed was not a small tripod, but what was stored in the small tripod. The small ding contained the Netherfire Essence obtained by Ling Yu in the Extremely Cold Desperate Realm of the Northern Regions back then, and the Netherworld Fire Essence, as one of the three major divine fires, had been baking the blood of all spirits, trying to smelt the left leg of the ambush, which was later obtained by Ling Yu.

And this Xiao Ding was included in the spirit of the world when the ring worn by the emperor of the python clan in the current realm, and the reason why the emperor collected the small tripod was not because the small tripod was of extremely high grade, but because the python clan was close to the dragon clan and liked shining jewelry. Xiao Ding's whole body exudes black light, which makes people feel that it is not an ordinary thing, so it was originally included in the realm spirit ring as a treasure. Later, Ling Yu unsealed the ambushed left leg, and the Nether Fire Spirit was also included in the mysterious wooden box by Ling Yu. At that time, the realm had not yet fallen into a deep sleep, so he secretly collected some Nether Fire Essence and put it in Xiaoding. Later, Ling Yu was circling among the various forces in the Northern Regions, and the Nether Fire Spirit was used up. It wasn't until the realm awakened again that he heard that Ling Yu wanted to refine the Ice Chalcedony Jade Dew Pill, so he handed Xiao Ding over to Ling Yu. The Ice Chalcedony Jade Dew Pill is one of the Seven Treasures of Incense, and it is very difficult to refine, so the flame required to refine it is also very special.

In Ling Yu's hand, he had the Vermilion Bird Divine Fire given to him by the Vermilion Bird Divine Beast, but the Vermilion Bird Divine Fire attribute was violent, and it belonged to the supreme yang and rigid flames, which was contrary to the attributes of the Ice Chalcedony Jade Dew Pill. If you use the Vermilion Bird Divine Fire to refine the Ice Chalcedony Jade Dew Pill, it is very likely to backfire and increase the difficulty of refining the pill. Therefore, if you want to successfully refine the Ice Chalcedony Jade Dew Pill, then you need to refine it with the Negative Fire to make it match the attributes of the Ice Chalcedony Jade Dew Pill. And the Netherworld Fire Essence originated from the Nine Shadows, which was suitable as the fire at the bottom of the furnace for refining the Ice Chalcedony Jade Dew Pill. In order to increase the probability of success in refining the pill, Wu Dao also specially laid out an ancient formation method containing yin fire attributes around him. Under the double insurance, Ling Yu felt that the Ice Chalcedony Jade Dew Pill could try to refine it. Ling Yu placed the Netherworld Fire Essence in Xiao Ding on the lower layer of the Forgotten Life Furnace, which was a special place for stacking flames, and the two sides were ventilated, which was more conducive to air intake and exhaust, increasing the fire.

After the furnace was opened, Ling Yu had been guarding the hearth, and he held his palms on the Forgotten Life Furnace, sensing the temperature of the flames in the furnace while carefully controlling the heat of the herbs. The Netherworld Fire Spirit is not as good as Fusang True Fire and Red Lotus Karmic Fire, it is a kind of strange flame that can reveal a trace of coldness in the flame, this kind of flame is extremely corrosive to the human body, and the same is true for medicinal materials. On the surface, it seemed that the medicinal herbs had not been melted, but Ling Yu had sensed through his divine sense that inside the herbs, the spiritual power was turning into spiritual liquid, mixing with other herbs. Ling Yu knew that if this continued, within three days, the herbs would completely melt. Under normal circumstances, it would take thirty days for the Ice Chalcedony Jade Dew Pill to come out, but Ling Yu didn't have that much time, so he asked Wu Dao to support him with a formation. In this way, the time required to refine the Ice Chalcedony Jade Dew Pill was greatly reduced. Ling Yu estimated that if nothing else, the Nine Heavens Dan would be completed.

Alchemy is very bitter, this was said to Ling Yu when he was awarded the inheritance of the Burning Sin. That was the first thing Sin Burning said to Ling Yu when he was teaching Dan Dao. All those who practice alchemy need not only the precise control of the flame and the mastery of the spirituality of all things, but also extremely strong concentration and patience. When refining medicine, the person in charge of the furnace cannot leave the furnace, because the process of turning herbs into pills may only be completed in an instant, and a quick or slow moment may make the furnace pill a waste product. Therefore, in these few days, Ling Yu must not slack off in the slightest, and must concentrate on alchemy.

In the first three days, Ling Yu ate and drank by the Forgetfulness Stove, and he didn't dare to leave, or even rest. Looking at Ling Yu's increasingly haggard appearance, Fu Chao and Wu Dao were a little worried in their hearts. Such a persistent refining of the elixir was a good thing, but it could also cause great harm to Ling Yu's body. However, since Ling Yu had chosen this path, they wouldn't say anything. During this time, Wu Dao and Fu Chao were also resting instead, and they decided that someone must be by Ling Yu's side to prevent accidents. This was the first time that Ling Yu had taken charge of the Forgetful Life Furnace refining the Divine Pill alone, so Wu Dao and the others did not dare to be careless.

At noon on the third day, Ling Yu stretched out his hands again and stuck them on the Forgetful Furnace, sensing the changes in the spiritual grass in the furnace. At this time, the herbs had indeed turned into milky white spiritual liquid, as Ling Yu expected, and those spiritual liquids were filled with a gentle white light, which made people yearn for endless and want to taste it.

When Ling Yu's hands left the Forgotten Furnace, he found that two clear handprints appeared on the black furnace wall, and there was white frost near the handprints. It's hard to imagine a furnace where flames are tumbling and the walls of the furnace are filled with frost that only falls in winter. Moreover, they are still in the middle of the sweltering southern wilderness, so this situation is even more surprising. However, Ling Yu and the others knew that the reason for this situation was entirely due to the flames at the bottom of the furnace and the properties of the herbs. The Nether Fire Essence is the Yin Cold Fire, and the Spirit Grass needed to refine the Ice Chalcedony Jade Dew Pill is also a cold thing.

On the evening of the third day, Ling Yu finally couldn't stay up a little anymore, his eyes were black, and his eyes were bloodshot. There are three most important steps in alchemy, and the first step is to open the furnace, which is the most critical step in alchemy. Because for many people who are not good at Dan Dao, it is easy to put the herbs with opposite attributes into the same furnace at the same time because of carelessness when the furnace is opened, and the result of this is that there is no need to wait for the herbs to melt at all, but just after heating, the herbs will turn into residues because of the repulsion of the attributes. Therefore, the first step is to test the alchemist's familiarity with the properties and efficacy of the elixir. The second step was the time that Ling Yu was experiencing now, that is, when the herbs melted. At this time, it needs to be tempered with a low fire, if the flame is too intense, then the medicinal effect in the spiritual fluid will wear off. Of course, the size of the flame also depends on the attributes of the herb to be refined, if it is a fire-type herb, it must be a fire.

And the third step is when it is about to be completed. That's the most important of the three steps. When the pill is about to be refined, the aura of heaven and earth will frantically pour into the pill furnace, and at this time, the person in charge of the furnace needs to be ready to start the furnace at any time. If it is one minute in the morning, the pill will be slightly insufficient and slightly flawed because it does not absorb the aura of heaven and earth. If it was one minute in the evening, then the elixir would explode in the furnace due to the absorption of too strong heaven and earth aura, making all efforts undone. Of course, these are only for ordinary pills. Like the Ice Chalcedony Jade Dew Pill refined by Ling Yu, this level of Divine Pill had to be even more cautious when it was furnaced. Because if this elixir is refined, it means that they will steal the opportunity of the Heavenly Dao, seize the creation of heaven and earth, and thus cause the wrath of the heavens. And at that time, it was also time to really test the Dan Dao master Dan Shu, whether or not Dan could be achieved depends on the Dan Dao Sage who is in charge of the furnace.

Ling Yu let out a long yawn, he turned his head to look at Wu Daohe and the ambush, and said softly: "Fat Wu, old bandit, you take care of me for a while, I'll rest first." After staying up for three days and three nights, my body was a little unbearable. "At this time, the pill has already melted, and there is really no need for Ling Yu to concentrate too much. After the most important step 1 and 2, the rest is just a matter of patience. After Ling Yu finished speaking, he hastily ate a mouthful of food, then lay on the ground, and lay down next to the forgetful stove. In less than a cup of tea, Ling Yu's heavy snoring sounded quietly, floating in this barren mountain.

Looking at Ling Yu's slightly haggard face, Fu Chao and Wu Dao glanced at each other, and they both showed a look of distress in each other's eyes. And Simba, since Ling Yu opened the furnace, has been letting out wind on the periphery. The Ice Chalcedony Jade Dew Pill is a rare elixir in the world, so it must not be disturbed by others.

Ling Yu slept for nearly five hours, and the next morning, the morning light broke into the valley, refracting the dew on the grass into a colorful halo, and the birds cried softly, waking Ling Yu up from his sleep. Maybe he didn't close his eyes for three days, Ling Yu had already stayed up and was dizzy, and this night, he slept very peacefully.

After getting up, Ling Yu washed his face, and when he sensed that the herbs in the furnace were not abnormal, he replaced Fu Chao and Wu Dao. With the first three days of suffering, Ling Yu has gradually adapted to this kind of life. So, out of the remaining six days, he only slept for three hours on the afternoon of the eighth day. On the morning of the ninth day, Ling Yu specially found a clear river to wash away her exhaustion. Now that it has reached the most critical moment, whether the Ice Chalcedony Jade Dew Pill can be refined depends on what happens when the furnace starts next. After cleaning, Ling Yu returned to the forgetful furnace, estimated the time, and prepared to start the furnace.

Ling Yu felt the change in the spiritual liquid in the furnace, and a satisfied smile unconsciously appeared on his face. He used his divine sense to sense that nine milky white pills were quietly placed in the Dan furnace at this time. They are like white pearls, rippling with a rich aura, showing the heavenly level of holy rhyme in the clouds and mist.

Ling Yu knew that there was still a quarter of an hour, and as long as it was a quarter of an hour, this furnace of elixir would be considered refined. And what he has to do now is to not let the vitality of the Ice Chalcedony Jade Dew Pill leak out. As long as you survive this quarter of an hour, then your first alchemy will be completed. However, often the heavens do not fulfill people's wishes. After Ling Yu had just had the idea of holding on for a quarter of an hour, a boundless hurricane suddenly blew in the sky, and the hurricane did not blow from a distance, but landed directly from the sky. When the wind and sand swept away, the ancient trees around were uprooted, and countless wild beasts were engulfed on the sky. At the same time, a thick black cloud instantly filled the sky, and blue lightning fell from the clouds, mixed with the majestic roar of providence. Although this dark cloud is not a thunderstorm cloud, it is definitely not an ordinary thunderstorm cloud. There was an oppressive aura in the clouds, as if the Heavenly Dao was furious and wanted to destroy all living beings with thunder.

"Boom!" As a dull thunder sounded, eighteen divine thunderbolts fell from the clouds, and they sealed all directions of the Forgotten Life Furnace respectively, and nine divine thunderbolts thundered down one after another in the center. Those divine thunders were comparable to Ling Yu's rebellious thunder punishment during the tribulation, and it seemed that they only wanted to destroy the Forgetting Furnace and the Spirit Pill.

Looking at Ling Yu who was in the midst of the thunderstorm, Fu Chao and Wu Dao could only look worried, but they couldn't step forward, let alone help anything. If it was an ordinary elixir, it would be fine, but with a heaven-level elixir of the level of the Ice Chalcedony Jade Dew Pill, the Heavenly Fury Intent it triggered was definitely not something that a few people could compete with. Even if the ambush is a powerhouse of the Supreme Realm, it can't do it!
