The top 50 spiritual fires are not that easy to get.

This requirement alone can keep most alchemists out.

This ranking of spiritual fire in heaven and earth is the essence of the world. Even in the vast spiritual moon continent, it is extremely rare. It is absolutely impossible to obtain a spiritual fire of heaven and earth of this level without certain opportunities and luck.

Therefore, most alchemists may have a high level of alchemy, but they will not be able to refine the Bu Tian Pill in their entire lives.

But this is not a big problem for Zhang Yifeng. He even has the power of the Netherworld Ghost Fire that exists.

As Zhang Yifeng thought, a ray of cold flame appeared in his palm.

The flame presents a dark light, which is the dark demon fire that he has subdued.

The Dark Demon Fire is not low on the Heaven and Earth Spiritual Fire List, but it is not very high. However, it is more than enough to refine the Heaven-Benefiting Pill.

Zhang Yifeng had a thought, and the dark magic fire in his hand suddenly jumped to the top of the alchemy furnace. The cold flames actually brought out the scorching temperature.

The temperature of the alchemy furnace rose rapidly in an instant.

"Blue silver flowers, broken dreams and stars, Tianyuan grass, back heart vine..."

While controlling the fire of the flame, Zhang Yifeng put the spiritual medicine needed to refine the Bu Tian Pill in sequence into the alchemy furnace and began to melt it according to the recipe of Bu Tian Pill.

Dark magic fire, cold outside and hot inside.

Not long after, the spiritual medicine he threw in was melted into drops of medicine.

Under the control of his huge spiritual consciousness, more than a dozen drops of spiritual medicine and liquid floated quietly in the alchemy furnace, independent of each other, without any intention of fusion.

Seeing this scene, Zhang Yifeng took a deep breath and his eyes instantly became serious.

"Next, it's time to invest in the Jiuxin Glazed Bead."

The Nine-Star Glazed Bead is a mysterious bead from the depths of the starry sky. It has the power of stars attached to it. Strictly speaking, it does not belong to a spiritual medicine. Except for the Heaven-Bood Pill, there is no elixir that needs to be used.

Because it can emit starlight like stars in the dark, in the Lingyue Continent, the nine-star glass beads are more used as decorations.

There is another very special thing about the Nine Star Glass Bead, that is, its texture is very hard and not easy to damage.

In the eyes of ordinary people, although the Nine Star Glazed Glazed Beads are precious, they seem to have no other effect except for being used as decoration accidents. However, in the eyes of alchemists, especially in the eyes of those alchemists with high-level spiritual fire in heaven and earth, the Nine Star Glazed Beads are rare treasures because they are essential materials for refining the Heaven-Repairing Pill.

The Nine-Star Glass Bead is not a spiritual medicine, but in the process of refining the Heaven-Booning Pill, it must be used as a guide to communicate the power of the heaven and earth and stars. Only in this way can it be refined into the Heaven-Booning Pill.

Zhang Yifeng had a thought, and saw the light of the storage ring in his hand flashing, and then a dark bead with a faint starlight appeared in his hand.

This is the Nine Star Glass Bead.

Zhang Yifeng did not directly throw the Nine-Star Glass Bead into the alchemy furnace, but instead carved a formation on the surface of the beads.

Carving formations on beads is simply difficult for ordinary formation masters to ascend to the sky, but for Zhang Yifeng, it is a slight effort.

In almost less than a breath, Zhang Yifeng portrayed the formation.

In fact, there was no need to carve the formation when refining the Bu Tian Pill, but in his previous life, Zhang Yifeng had invented an alchemy method that could improve the quality of refining the Bu Tian Pill through research, that is, carve the formation on the Nine-Star Glass Beads.

Although the Nine Star Glass Bead can absorb starlight by itself, the starlight it absorbs is very limited. The quality of refining the Heaven-Booning Pill and forming the elixir is closely related to the starlight contained in the Nine Star Glass Bead.

It is precisely because of this consideration that Zhang Yifeng thought of using the method of portraying the formation to increase the speed of the nine-star glass beads absorbing starlight and its ability to accommodate starlight.

In his previous life, Zhang Yifeng was just an alchemist and did not know how to form. Therefore, when he was refining the Heaven-Booning Pill, he asked a formation master to help. It happened that the formation master was in the spirit fire of heaven and earth, so he was able to melt the Nine-Star Glazed Beads.

In the end, although the pill was refined, he also owed a considerable favor. For this, he paid three Heaven-Repairing Pills as a price to repay the favor.

As the formation was portrayed, the nine-star glass beads that were originally emitting dim starlight suddenly became brighter. In the dark, it seemed to be pulled, and the starlight in the sky passed through the house and rushed towards the nine-star glass beads in Zhang Yifeng's hand.

Seeing this scene, Zhang Yifeng's mouth curled slightly, and he showed a satisfied smile.

“It’s now.”

When the starlight on the Nine Star Glass Bead formed a halo on the surface of the bead, Zhang Yifeng shouted lightly and instantly threw the Nine Star Glass Bead into the alchemy furnace.

Buzzing!

As soon as he threw the Nine Star Glass Bead into the alchemy furnace, the alchemy furnace began to vibrate slightly, and as time went by, the frequency of the alchemy furnace vibrated faster and faster.

Even under the rapid vibration, the Dan Furnace left the ground and floated in the air.

"Change!"

Zhang Yifeng looked solemn, and suddenly increased his firepower, activated the Blue Moon Fire to the extreme, constantly burning the alchemy furnace.

As the power of the flame increased, a slight explosion suddenly sounded inside the alchemy furnace, and then countless starlights surged out of the alchemy furnace, illuminating the room brightly.

"Starlight back!"

Zhang Yifeng shouted again, and saw that the starlight that had originally radiated from the air suddenly crawled back into the alchemy furnace.

"Nine turns!"

The Dan Furnace, which had originally vibrated violently, stopped vibrating and began to rotate rapidly.

At the same time, there were sounds of mysterious sounds coming from the alchemy furnace, just like the depths of the vast universe.

"The starlight sounds up, the sky-repairing pill is formed, condensed!!"

Zhang Yifeng's face was happy. He instantly pinched a magic trick with both hands and penetrated it into the alchemy furnace. Then, he reduced the fire and continued to burn the alchemy furnace.

About three minutes later, a refreshing fragrance came out of the alchemy furnace.

Zhang Yifeng looked happy. He knew that this was the medicinal fragrance produced after the success of the elixir.

"receive!"

Zhang Yifeng removed the flames and shot a elixir technique into the alchemy furnace.

The next moment, twelve black and shiny round pills flew out of the elixir and fell accurately into a jade bottle that Zhang Yifeng had prepared long ago.

"There are only twelve pieces. Fortunately, there are ten of them top-grade and two top-grade pieces, so it's still a barely doubling."

After checking the quality of the elixir in the jade bottle, a satisfied smile appeared on the corner of Zhang Yifeng's mouth.
Chapter completed!
