Soon, Gu Yifeng came out of the Huangquan Cave and saw Miao Xuanzi and Huang Jiuyin sitting on the ground drinking tea outside, and he was a little surprised for a while.

"Coming out? Then let's go, it's time to go back to the sect. ”

Miao Xuanzi's face did not change, and said with a smile, Gu Yifeng nodded immediately.

"I hope you won't come back to the capital next time."

Huang Jiuyin just said indifferently, and then continued to drink tea in the same place, for the people of the hidden capital, this underground world is heaven and earth, and if it is not necessary, it will basically not leave the hidden capital.

It is precisely because of this that Huang Jiuyin would have said this, if it weren't for Miao Xuanzi, with his protection and grudges, he would not know how many times he died at this moment, not to mention that Huangquan Sect had also prostituted a secret realm to cultivate.

Miao Xuanzi didn't say much, it's not good to make enemies, but a certain amount of pressure can also promote growth, especially for a genius like Gu Yifeng.

The two of them went out of the secluded capital, boarded the back of the goshawk again, braved the wind, and returned to the Changchun Valley in three days.

Gu Yifeng directly found Zhuang Qingqian and explained his intention.

"You mean, you're going to refine the Seven Rank Pill?"

Zhuang Qingqian asked with some surprise.

"Yes, in this auction, I have already collected all the main materials of the Void Refining Pill, and now I want to refine a Void Refining Pill, but the Seven Rank Pill, I don't have much control over it, I hope the Valley Master can help the disciple."

Gu Yifeng spoke slowly, but this word was no less than thunder in Zhuang Qingqian's ears.

The difference between the refining of the seven-pinned pill and the seven-pin pill is that when the seven-pinned pill is refined, in the end, the Cheng Dan will be as if it comes to life because of the fusion of medicinal power.

The seven-rank pill refined by a high-level alchemist even has a certain chance of giving birth to spiritual intelligence, so the most important thing is the manipulation of the technique in the Cheng Dan stage.

"In that case, the rest of the medicinal materials, the old man will prepare them for you, but the Dan Furnace and the Alien Fire need to come by yourself, is it okay?"

Zhuang Qingqian nodded slowly and looked at Gu Yifengdao.

"It's okay, it should be enough."

Gu Yifeng slowly spoke, Shennong Ding and Dragon Phoenix Black Flame were basically the top match, and the whole continent could not find an alchemist with such a configuration.

……

The three-day appointment with the valley lord Zhuang Qingqian was fleeting, and Gu Yifeng came directly to the mountain behind Changchun Valley under the leadership of Miao Xuanzi, a vacant land with no one.

He took out Shennong Ding directly, Zhuang Qingqian didn't see it from a distance before, but now when he looked closely, a smell of aged medicine came out from the tip of his nose, even he was a little intoxicated.

The grade of this alchemy furnace will never be low.

Gu Yifeng directly patted the Shennong Ding with both hands, and the black flames of the dragon phoenix surged, falling into the Ding, and suddenly turned into a sea of fire, constantly raising the temperature in the furnace.

"Very good, now the old man and Miao Xuanzi will stabilize your alchemy furnace, all you have to do is extract the essence of the medicinal power. Refining the Sky Pill is the most important heat, so you must grasp the time well and do not delay. ”

Zhuang Qingqian instructed, and then shot at the same time as Miao Xuanzi, and instantly raised a formation under his feet, spreading with Shennong Ding as the center.

The two have been working together for a hundred years, and they have long had a tacit understanding, but the formation they cast at this time is the formation required for joint alchemy, and the people in the formation only need to input their own strength to turn it into fuel and maintain the strength of the alien fire in the alchemy furnace.

As far as the alien fire is concerned, the flame with a level lower than oneself is the best ration, and the two flames of one tiger and one dragon mastered by Miao Xuanzi and Zhuang Qingqian are directly devoured by the dragon phoenix flame like a chicken.

"It's such a strong fire."

Seeing that Dragon Phoenix Black Flame was so active, Zhuang Qingqian and the others couldn't help but exclaim.

Gu Yifeng on the side could only smile when he heard this, and continued the movements in his hands, and when he was running the Dragon Phoenix Black Flame at full strength, the speed and quality of extracting medicinal essence were greatly improved.

Indeed, his alchemy still needs to be cultivated, although the control of the power of the divine soul is already very good, but for a senior alchemist, it is still immature.

It took about an hour for him to extract all the medicinal essence of the Refining Sky Pill, and the most difficult thing was the Ethereal Grass, because it contained the power of space, so the requirements for flames were also extremely strict.

If you are not careful, this ethereal grass will directly turn into ashes and dissipate.

Gu Yifeng spent two more incense sticks to refine the medicinal essence of the ethereal grass, and then sent it into the Shennong Ding in turn, and the next thing to do was to condense it again, that is, to refine the spirit.

The operation of refining the spirit is much simpler, it only takes half an hour to go through all the medicinal materials, and finally melt the spirit and become a pill.

Gu Yifeng walked into the formation very interestingly, used the power of the divine soul to manipulate the alien fire, and the mastery of the essence was directly transferred to Miao Xuanzi and Zhuang Qingqian.

The two old men are familiar with the road, even if it is a seven-grade Refining Empty Pill, under the joint efforts of the two, it is just like an ordinary pill, and the stage of melting the spirit will be completed soon.

The next step is Cheng Dan's link, Zhuang Qingqian let out a low shout, and the power of the divine soul exploded instantly, and a bamboo cultivation phantom appeared behind him, leading straight to heaven and earth.

Under the suppression of the divine soul projection, many medicinal essences fused together and slowly turned into a ball.

"Fuel up!"

Miao Xuanzi let out a low snort, and a divine soul phantom also appeared behind him, it was a blue dragon, and as the dragon's groan dispersed, the essence of medicinal power was completely condensed into a ball.

Gu Yifeng was full output, and the red and blue dragon soul emerged, slowly opened his mouth, and even spit out a flame, which blended with the black flame of the dragon phoenix, and constantly roasted into a ball of elixir prototypes.

After about a stick of incense, the water continues to evaporate, and at the same time, a stream of danxiang comes out.

"Forbidden Sky!"

Gu Yifeng had expected it, and with a low shout, hundreds of runes spread across the body of Shennong Ding's body in an instant, directly sealing the space inside the tripod and imprisoning all spatial power.

This is the real difficulty of refining the empty pill, after becoming a pill, the elixir will burst out of the power of space and directly escape into the void space, so you must pay attention to the blockade of the space power when refining the pill.

Gu Yifeng had already prepared, and directly cast the forbidden space talisman recorded on the Wanzong rune, which was able to seal the space of the item pasted, so that it could not be transferred or teleported.

Shennong Ding was sealed, and the Dragon Phoenix Black Flame also reached the last step, and with a roar, he swallowed the pill into the dragon head turned into flames, and dissipated instantly after three breaths.

At the same time, a silver light flickered, emanating from the Shennong Ding, refining the void pill!

Almost at the same time, Gu Yifeng's figure rushed out directly from the side of Shennong Ding, and a mountain collapse fist was unleashed, and the shattering fist intent erupted, directly shattering all the clouds in the sky, including the clouds that had not yet condensed and formed.

But this was just the beginning, he directly condensed the dragon phoenix black flame, turned into a fire dragon and kept shuttling around, a whole stick of incense for a whole time, and then stopped.

For the sake of insurance, Gu Yifeng even carved hundreds of runes, turning them into a splitting sky rune array, and directly tearing them apart once the clouds appeared.
