In the middle of a dark road, three figures slid rapidly downward.

"It's so hot!" Jiang Feng's spiritual power in his whole body worked.

"Be careful, master!"

Dongfang Li's dark red Lihuo Gang Yuan Force formed a flame halo, wanting to shelter Jiang Feng.

The closer they got to the center of the earth, the higher the temperature became, and waves of fire seemed to begin to surge in the air, both Jiang Feng and Dongfang Li could make their bodies glide with their strong strength, but this intense temperature affected their performance.

"Ice Armor!"

Jiang Feng felt the intense temperature constantly scorching himself, and he knew that he had begun to approach the lava in the center of the earth, and the aura in his body instantly gushed out, quickly forming a layer of frost on the surface of his skin.

It's not a magic weapon.

It's just an innate spell.

Condense a battle armor with spiritual power, the battle armor covers the whole body, which is used to protect the whole body, and the spell of the cold ice armor is an ice spell, which can also reduce the temperature in the air.

"What a pure flame!"

Dongfang Li's own cultivation is the practice of fire attributes, although it belongs to yin fire, but he did not resist the fire in the center of the earth, and the powerful flame aura made him crazy and began to absorb it, and he was a little happy.

Sneer!!

Kurono is a poisonous snake, it likes to survive in dark places, so it hates flames, the more it enters the center of the earth, the more uncomfortable it feels, but the scales on its body are indestructible, but it blocks a lot of fire breath for it.

"Boom!"

In a piece of lava, there was a rock that had not been melted, Jiang Feng stood firmly, but as soon as he landed, his feet were forced, and the rock was shaken, almost cracking the rock, and he even felt a slight illusion of collapse, he took a deep breath, looked around, and said indifferently: "We are alchemy here!"

This time the alchemy is different from the last one.

The last time he gave Shen Mo the Ding Gu Pill was refined by himself, but it was not so much alchemy as it was dispensing, basically after cultivating and running in various medicinal materials, at most, after boiling it again, the Ding Gu Pill came out.

But this time alchemy, it is necessary to refine the medicinal power, and then it must be smelted, the refining of the medicinal power is not a simple job, to do not waste the medicinal power, and can perfectly refine the medicinal power in the medicinal materials, which not only requires special techniques, but also a Dan furnace.

However, Jiang Feng did not have a Dan furnace, and he did not put out a strange fire, a different fire that could be burned for the Dan furnace, so he could only rely on the natural Dan furnace.

On any planet, the center of the earth is a natural furnace.

The temperature of the air here is already very high, more than a thousand degrees, and the temperature of the lava should allow him to refine the elixir.

It's not impossible to go in again, but it will consume too much of their cultivation.

Alchemy also requires cultivation, and he must maintain peak spiritual power in order to refine a pure pill.

"Master, we can't stay here for too long, or we'll be melted by the air!" Dongfang said as he landed beside him.

"Whew!"

Kurono's huge body also crossed his knees, coiled into a ball, his body rolled solidly, spitting snake letters, and a pair of dark snake eyes carefully examined the four directions.

"Dongfang, plant the nine flags!" Jiang Feng took out the nine small flags and handed them to Dongfang Li.

"It's ......"

"Array Flag!"

Jiang Feng said: "There is my spiritual power on it, it will not be melted by the lava, you are twenty meters away from me, in the direction of the ninth palace, insert it!"

"Good!"

Dongfang Li nodded, his eyes scanned, his light skills were not the best, but with his innate cultivation, this little bit of work was still no problem.

His body was like a streamer, his toes were on the lava, and with the help of his strength, he directly planted a formation flag.

Then there is the second side, the third side......

It took more than ten minutes, and a lot of cultivation was consumed, before he planted the nine array flags.

"The fire of heaven and earth, in my name, rises!"

Jiang Feng sat cross-legged, sitting in the center of the nine array flags, unintentionally facing upward, pinching the seals with both hands, one by one the handprints were constantly changing, the spiritual power in his body was condensed, and his spiritual power turned into flames, like a little spark in the flames, igniting the starry sky.

Woohoo!!

In the lava, the flames rolled up, like a fire dragon circling and staggering, intertwined, as if forming a furnace, and Jiang Feng and Dongfang Li and Hei Ye, two people and one demon, were in this furnace.

"Huh?"

Dongfang Li was a little strange: "It's not hot!"

"This formation can absorb the power of lava, and it can also isolate the power of lava!" Jiang Feng unloaded the ice armor spell on his body and let out a long breath.

This is the Nine Dragons Alchemy Formation.

The fire dragon formed by the power of the nine lava is a Dan furnace, this Dan furnace is like a magic weapon that cannot be moved, controlled in Jiang Feng's hands, it can resist the enemy, protect itself, and also alchemy.

"The head of the family is talented!" Dongfang centrifugal took his hand orally, and he felt more and more that Jiang Feng was unfathomable.

"Whew!"

Kurono was also happy, and his coiled body relaxed, and finally he didn't have to roll in the fire.

"Oriental, medicinal herbs!"

"In!"

Dongfang Li opened a long jade box on his back, and there were all kinds of medicinal materials lying inside, among these medicinal materials were twenty hundred-year-old ginseng, and the others were basically picked by Jiang Feng through medicinal books such as the Compendium of Materia Medica, which were comparable to the drugs of the fairy world, and he went to the major pharmacies to pick them up.

Jiang Feng has recently read a lot of books on medicinal materials, such as the Compendium of Materia Medica, Shennong's Materia Medica, and ...... There are many medicinal herbs on the earth whose names are different from those of the Tailong Star Domain, but in terms of judging medicinal power, Jiang Feng is the best, so this is not difficult for him.

"Refine the ginseng pill first!"

Jiang Feng thought about it for a while and decided to refine the ginseng pill first.

The meaning of ginseng pill is to refine the medicinal power in ginseng and condense it into Dan, which is much more effective than eating raw ginseng.

Rumble!

In the Dan furnace, Jiang Feng pinched the seal, and the Nine Dragons spit fire, condensing into a dark golden flame.

"Dongfang, throw fifteen ginseng into the flames!"

Jiang Feng said in a deep voice.

"Yes!"

It's not the first time Dongfang Li has seen people alchemy, back then, the Demon Sect was also a famous cultivation sect, and there were also seniors in the sect who refined pills, but it was the first time he had seen someone do such alchemy.

Fifteen ginseng ginseng was thrown into the golden flames, and the flames became more and more vigorous.

"One refinement!" Jiang Feng changed his handprint, and the flames were changing color.

"Second refining!"

"Three refinements!"

With the flame of the third refining burning, he felt that he was a little struggling, practicing the seventh layer of qi, for alchemy, the cultivation was still insufficient, if he had the golden pill cultivation, such an elixir, a handprint would be solved.

"Four refinements!"

"Five refinements!"

"Six refinements!"

After the sixth refining, Jiang Feng didn't dare to try it anymore, although this kind of "Thousand Refining Fire Seal" is an ancient alchemy technique, it is rumored that there are a thousand refining, refining to the extreme, the medicinal power is not only purified but also qualitatively changed, but even if he cultivated to the Void Realm in his previous life, he only reached three hundred refinements.

Now that he was cultivating the realm of the seventh layer of qi, the sixth refining had exhausted his cultivation.

"What a fragrant and pure medicinal power!"

Dongfang Li's eyes burst out with a different color, and he couldn't help but swallow a mouthful of saliva as he looked at the golden flames that gradually condensed into a shape.

"Snort!"

Kuroye's snake letter also spit out, the snake's eyes were burning, if it wasn't for his opening a lot of spiritual wisdom, it would probably have pounced directly by now, this smell is too attractive to it.

Jiang Feng's handprints were changing, and the dark golden flame became more and more vigorous, and it took three hours of refining before the golden flame gradually extinguished.

"Dancheng!"

He opened his eyes and looked at the one hundred and fifty ginseng pills gently suspended in front of him, and a smile appeared on his face: "One Grade Spirit Pill!"

The first alchemy on the earth, the start was good, he thought that he could become a hundred and twenty pills at most, but he didn't expect to be able to become a hundred and fifty pills, which is definitely a super level of performance.

Hundred-year-old ginseng is a first-grade elixir, just eat it like this, it is too wasteful of medicinal power, and less than one-third of it can be absorbed, and the elixirs in it are all high-grade elixirs, and they can absorb more than 80% after eating.

About three elixirs are equal to the medicinal power of a ginseng, and after refining it, he can at least triple the medicinal power.
