In the "Primary Alchemy Collection": Alchemy furnaces are also divided into grades. The higher the grade of the alchemy furnace, the better the elixir refined, and the speed and success rate are much higher. Alchemists, using their own alchemy furnaces, can be said to be even more handy.

And the flame in this alchemy furnace is not ordinary fire. The fire spirit of this flame can be engraved on the alchemy furnace, and it can be controlled by the spiritual power of the controller, so that flames can be born in the alchemy furnace. And this extraordinary flame can also be divided into many kinds, but the "Elementary Alchemy Collection" is only mentioned in passing and does not explain in detail.

Of course, if the fire spirit engraved in the alchemy furnace is more extraordinary, the better the elixir will be.

Yu Chengfeng picked up the alchemy furnace that was no bigger than a palm in one hand and looked it up and down. After a long time, Yu Chengfeng still decided to figure out how to ignite the fire spirit engraved in the alchemy furnace first.

So, Yu Chengfeng held the alchemy furnace in the palm of his hand, and transported a stream of spiritual power into the alchemy furnace, and at this moment, Yu Chengfeng's divine consciousness also ran into the alchemy furnace with this spiritual power.

This spiritual power swirled inside the alchemy furnace, and a divine sense also probed how to stimulate the fire spirit in the alchemy furnace.

After a long time, the divine consciousness felt nothing but the dead silence of the alchemy furnace. I don't know what kind of material it made this alchemy furnace, but it actually made Yu Chengfeng feel a burst of coldness, which made Yu Chengfeng shudder, and his complexion changed again and again.

The matter of cultivating immortals really makes a person with scientific and technological civilization puzzled. Yu Chengfeng's eyebrows furrowed slightly, the alchemy furnace was not a living body, how could there be a fire spirit stored in it?

Immediately after, Yu Chengfeng's eyes slowly closed, trying to meditate, trying to listen to the tiny sound driven by the slightest spiritual power pouring in.

But until a few hours passed, the alchemy furnace was still motionless, and there was no abnormal reaction.

"This is a lifeless thing, how can it attract people?" Yu Chengfeng complained, opened his eyes, and glared angrily at the alchemy furnace in his palm.

Immediately, Yu Chengfeng laughed at himself again, since it was said in the "Primary Alchemy Collection": If you want to ignite the fire spirit, you must attract the body of the alchemy furnace, if not, you can't refine the pill. There must be some truth in this.

After being silent and thinking about it for a long time, Yu Chengfeng closed his eyes again and tried to use his spiritual power to hold up the alchemy furnace.

When a stream of spiritual power wrapped around the alchemy furnace, the alchemy furnace slowly rose from Yu Chengfeng's palm. And although Yu Chengfeng closed his eyes tightly, he could still feel the location of the alchemy furnace.

At the same time, in addition to the spiritual power that was entwined around the alchemy furnace, there was also a sense of consciousness slowly wandering around the alchemy furnace

Since it is necessary to attract each other to the alchemy furnace, presumably the person who uses the alchemy furnace must not regard the alchemy furnace as a dead thing, but must regard it as a living creature and have feelings for it.

But although I understand this truth, how can I establish feelings for an object?

Thinking of this, Yu Chengfeng, who had his eyes closed, frowned slightly, he didn't expect this immortal cultivation to be a real headache.

After a long time, Yu Chengfeng slowly exhaled a breath, thinking back to whether it was the enlightenment of the immortal method or the preparation of dust-free water, which seemed to be closely related to some truths in life and the trajectory of all things.

Yu Chengfeng, who is a human being in two lives, must be very different in thinking and insight from people in this world. The hardships of entrepreneurship in the previous life were also twists and turns, but through guò's persistent belief and diligence, Yu Chengfeng in the previous life still moved towards success.

And now, although Yu Chengfeng didn't notice how to feel the fire spirit in the alchemy furnace, he didn't have the slightest desire to give up.

In this way, Yu Chengfeng sat for a few days, and in these few days, Yu Chengfeng absorbed spiritual power while feeling the breath of the alchemy furnace with his mind.

Finally, on the fourth day, there was an unexpected change.

I saw that the spiritual power that Yu Chengfeng exerted around the alchemy furnace, for some reason, suddenly disappeared, and the alchemy furnace also fell to the ground with no spiritual power.

With the sound of the "bell", with the landing of the alchemy furnace, Yu Chengfeng dared to open his eyes hurriedly, but he wanted to see if there were any changes in the alchemy furnace for the first time.

But when Yu Chengfeng saw the alchemy furnace in front of him, a complicated look appeared on his face

I saw that the alchemy furnace was lying flat on the white ground, without the slightest change. Since there is no change, why did the spiritual power that Fang just exerted disappear for no reason?

Yu Chengfeng pondered while picking up the alchemy furnace in his hand.

Just when the spiritual power surrounding the alchemy furnace disappeared just now, Yu Chengfeng seemed to feel the alchemy furnace, as if he was the alchemy furnace. This feeling is very wonderful, there is no need to deliberately feel the storage of the alchemy furnace, it seems to have been by Yu Chengfeng's side from beginning to end.

After pondering for a long time, Yu Chengfeng used a spiritual power to hold up the alchemy furnace.

At this moment, he was not using his mind to spy on the inside of the alchemy furnace, but only used his spiritual power to hold it up.

In the next few hours, Yu Chengfeng used both his heart and mind, one side exhaled the spiritual energy of this world, and the other used spiritual power to float alchemy in the air.

Finally, Yu Chengfeng's mind seemed to be connected with the alchemy furnace, and he could clearly feel the heat in the alchemy furnace.

At the same time, the spiritual power that surrounded the alchemy furnace frantically poured into the alchemy furnace

Feeling this, Yu Chengfeng was overjoyed, dared to open his eyes hurriedly, and continued to inject spiritual power into the alchemy furnace.

I saw a trace of golden spiritual power slowly heading towards the alchemy furnace, and all these spiritual powers were submerged into the alchemy furnace. Gradually, there was obviously a layer of psychedelic brilliance surrounding the alchemy furnace.

As more spiritual power was infused, the alchemy furnace seemed to tremble with excitement, and the frequency became faster and faster.

Suddenly, an extremely dazzling light emanated from the alchemy furnace's body, making Yu Chengfeng dare to hurriedly block his sight with his hands. After a while, Yu Chengfeng removed his hand, only to see a small flame burning inside the alchemy furnace, don't look at this flame Although the flame is small, the light is very large, and Yu Chengfeng, who is less than three feet away from the alchemy furnace, can feel the heat emanating from the flame.

At this moment of distraction, the flame suddenly became a little smaller. Seeing this, Yu Chengfeng's spirit was stunned, and he dared to be busy injecting spiritual power, and with the injection of this spiritual power, the flame in the alchemy furnace returned to its original state.

Seeing these changes, Yu Chengfeng also knew that the flames in this alchemy furnace must be injected with the spiritual power of the controller in order to make it immortal.

One side was constantly infused with spiritual power and poured into the alchemy furnace, and the other side stared at the flames in the alchemy furnace.

Seeing that the flame in the alchemy furnace had been burned, Yu Chengfeng was slightly excited in his heart, and after the corners of his mouth were raised, he used a trace of spiritual power to take out some clear water from the white gourd.

Under the control of Yu Chengfeng's spiritual power, the clear water, which was less than a small cup, slowly floated into the air like a thin snake, and finally formed a small water ball.

Immediately, Yu Chengfeng controlled these spiritual powers and began to remove the dust from this clear water.

I saw that the black impurities in the clear water gradually emerged from the surface of the water balloon, forming a black gas and scattering in all directions.

Half an hour later, the dust in the clear water had not been completely eliminated, but Yu Chengfeng was sweating profusely, only feeling that the spiritual power in his body was exhausted, and his mind seemed to be very stuffy.

While injecting spiritual power to control the flames in the alchemy furnace, while refining dust-free water, Yu Chengfeng's spiritual power was greatly lost. And controlling the flame and refining dust-free water can be described as dual-purpose. Refining dust-free water itself should be extremely concentrated, although Yu Chengfeng felt that his spiritual power was overdrawn at the moment, but he was able to divide the happiness of one side to keep the flame in the alchemy furnace unextinguished, and the other side to refine dust-free water, it can be thought that his spiritual power is quite unusual.

Gradually, Yu Chengfeng only felt that his mind was extremely dizzy, and the spiritual power in the other body seemed to be about to be exhausted, and the spiritual power created by the world in his body could not supply the spiritual power that the flames in the alchemy furnace wanted to absorb.

Finally, Yu Chengfeng seemed to be unable to hold on, his spirit and spiritual power were loosened, and the floating water balls and alchemy furnaces also fell.

With a "bang", the unrefined water spilled on the ground, and then, after the alchemy furnace landed, the small flame inside was also extinguished.

"Whew" Yu Chengfeng exhaled loudly, at this time, he felt extremely tired both physically and mentally, he never expected that refining the pill would be so difficult, and it would consume spiritual power and spiritual power so much.

After wiping off the dense beads of sweat on his forehead, Yu Chengfeng grabbed a handful of Qi Gathering Pills and stuffed them into his mouth, then came to the Dan Rack, found some other pills to eat, and then sat back in place.

In the past few days, Yu Chengfeng has eaten the Qi Gathering Pill as a meal, which has increased the spiritual power in his body a lot, and he can clearly feel the strength of his body.

After sitting for a long time, Yu Chengfeng Tong Guò Pill quickly recovered.

After taking a slow breath, he used his spiritual power to pour it into the gourd containing the clear water, and lifted out all the clear water in the gourd.

The clear water formed a large water ball in the air, and Yu Chengfeng closed his eyebrows, wanting to refine all the clear water of this gourd into dust-free water first, and was considering refining the elixir.

After a while, the black gas in the clear water ball continued to bubble and dissipate

I don't know how long it took, the dust in the clear water ball seemed to have been refined clean, and as Yu Chengfeng's spiritual power swam, the clear water ball gradually turned milky white.

After refining the clean water into dust-free water, Yu Chengfeng put all this dust-free water into the gourd, and was about to light the flame in the alchemy furnace again, when he heard a voice suddenly sound in his heart.

"Ride the wind, are you inside?"

This voice that suddenly appeared in his heart really startled Yu Chengfeng. After being stunned for a long time, he realized that this voice seemed to be coming from the powerful spiritual power of Xuanyi Daoist Tong Guò.

What did he come to me for, wouldn't it be any good?

After thinking about it, Yu Chengfeng secretly rejoiced in his heart, patted his buttocks, and walked towards the outside of the Danfang with anticipation.
