Xiao Yu looked at the large colorful spiritual liquid in the Huanyun Refining Heavenly Furnace, and after pondering for a moment, he directly threw the last medicinal herb wolf poison grass into the Dan furnace.

After only two breaths of effort, the rich fire spiritual energy in the furnace roasted the black-purple wolf poison grass to a shriveled one, and at the same time, a faintly bubbling ball of venom was suspended in the Huanyun Refining Heavenly Furnace.

"No, we have to refine it a little more... ”

As soon as the words fell, Xiao Yu increased the output of the spiritual energy in his hand, which also made the temperature in the already scorching Dan furnace increase a lot again.

"Turn!"

Feeling that the temperature in the furnace had reached his requirements, Xiao Yu's hands trembled suddenly, and at the same time, the two spiritual energy chains linked to the furnace wall also involuntarily turned.

A moment later, the high-speed rotating aura chain drove the colorful spiritual liquid ball to slowly rotate in the same direction.

After about a quarter of an hour, seeing that the rotation speed of the spiritual liquid ball had reached its limit, Xiao Yu once again strengthened the output of the spiritual energy, and at the same time, even more ferocious flames also burned in the Dan furnace.

"Refining with fire, and throwing out impurities at the same time, how do I feel that this Huanyun Refining Heavenly Furnace is getting easier and easier to use the more I use it... Xiao Yu said to himself with a smile while controlling the aura.

"Whoosh... ”

The speed of the spiritual liquid ball's rotation did not slow down in the slightest, and at the same time, the fire attribute aura that enveloped it was also sparing no effort to refine the essence and remove the dross.

When the two reached a state of mutual equilibrium, dark spots appeared on the orb, and as time went on, the black dots of different sizes became more and more numerous, and in the end, they even completely enveloped the original orb.

"Okay, go on!"

Seeing this scene, Xiao Yu's hands suddenly withdrew, and the flames surrounding the spiritual liquid ball also lost their support at the same moment, and then dimmed.

Without the barrier of the outer flames, the impurities covered by the spiritual liquid ball were also unbound at the same time and thrown on the inner wall of the Dan furnace.

"Whoa... ”

At this moment, there was a continuous sound of squeezing in the entire Huanyun Refining Heavenly Furnace, which also showed that the impurities that had been thrown out were terrifying.

Seeing that the spiritual liquid ball was getting smaller and smaller, and the sound in the Dan furnace was still non-stop, Xiao Yu couldn't help frowning.

"Why do there are so many impurities in the herbs that have become essences... Don't... Am I doing it wrong?"

Xiao Yu thought about it, and couldn't help but get nervous in his heart, although the various medicinal herbs that Luan Yu brought him were enough for him to squander, but he didn't want to waste these old precious medicinal materials at will.

It's just that the spiritual liquid in the Dan furnace didn't care about Xiao Yu's mood at this time, and it shrank again by as many as two circles at the stall where he was worried.

Seeing that the originally relatively large spiritual liquid ball had now become only one-tenth of it, even compared to the black and purple venom ball next to it, Xiao Yu couldn't help but slow down the spiritual energy output again, wanting to control the continuous consumption of spiritual fluid.

However, at this moment, the sound of those continuous clatters stopped instantly, and the black spots surrounding the spiritual liquid also disappeared completely.

"Success... It's done?" Xiao Yu was obviously a little caught off guard by the surprise that suddenly appeared, and the continuous output of spiritual energy couldn't help but pause, and then the high-speed rotating spiritual liquid ball slowly stopped, revealing its current appearance.

"All that's left ... So much?"

Xiao Yu looked at the spiritual liquid ball suspended in the Dan furnace, and then looked at the venom ball that had been waiting for a long time on the side, Xiao Yu unexpectedly found that these two completely different things had become equal in size.

"And... The color has changed. ”

It turned out that the colorful spiritual liquid ball itself had actually fused into a white liquid medicine under Xiao Yu's continuous refining, and when placed together with the venom ball next to it, it actually formed two distinct contrasts, one black and one white.

"These two colors ... It's a bit like Tai Chi... Anyway, it's time to move on to the next step. ”

With that, Xiao Yu took a deep breath, and then under the control of his hands, he pushed the white spiritual liquid ball towards a corner of the Dan furnace, and the black and purple venom ball was brought by him to the middle of the Dan furnace.

"Whew... ”

Familiar with the road, Xiao Yu once again controlled the aura in his hand and refined the venom ball in the same way.

Yet, after about half an hour ...

"No, it's too little! It's not proportional to the orb. ”

It turned out that after Xiao Yu completed the refining work, the originally small black and purple ball actually became a lot smaller after removing impurities, and if it was fused with the spiritual liquid in this state, I am afraid that it would not have the effect he wanted at all.

"And ... Look at the two plants!"

After Xiao Yu made a rough estimate, he threw the other two wolf poison weeds into the Dan furnace.

About half an hour later, Xiao Yu placed two small balls of different colors in the center of the Dan furnace at the same time.

"Well... The size is just right, and it looks like it's time to move on. Xiao Yu repeatedly observed the two small balls in the furnace, and after a while, he breathed a sigh of satisfaction and said.

Immediately after, Xiao Yu once again increased the output of spiritual energy in his body, and formed two scorching flames, squeezing the small balls in the Dan furnace in each other's directions.

"Well, what a strong repulsion?!"

However, just when the black and white balls were about to touch each other, there was a repulsion force between the two that could compete with him, and as Xiao Yu continued to strengthen his strength, that repulsion force could always reach the same strength as him, stubbornly preventing the two balls from fusing with each other.

"Come closer!

"Nima, I don't believe you're evil!

“。。。 What the hell is going on?"

"No, if I continue like this, my aura will be almost exhausted. ”

Xiao Yu used all the strength to eat, but he couldn't push the two small balls together, and at the same time, after two hours of continuous consumption, the aura in his body was already on the verge of drying up.

"Whew... ”

After a while, Xiao Yu, who had no achievements, couldn't help but exhale a breath of turbidity, and then he slowly reduced the output of the spiritual energy, leaving only the strength that barely kept the Dan furnace running.

"Why does rejection arise ... I've never seen this before... ”

"Because the herbs are too old? No, even if they have produced souls, they won't form such a strong repulsive force... ”

"Is it because of the difference in the medicinal properties of the two? Hehe, one white and one black are exactly the same as Tai Chi. ”

After Xiao Yu swallowed a Heaven Replenishing Pill, he looked at the two diametrically opposed medicinal liquid balls in the furnace, Xiao Yu couldn't help but talk to himself, but at this moment, his eyes suddenly widened, and an expression of sudden realization also appeared on his face.

"Tai Chi, that's right, it's Tai Chi, since they are mutually exclusive, then I can't force them together, so... If you rotate it in the way of Tai Chi ... That repulsive force will not find an equivalent target. ”

Thinking of this, Xiao Yu didn't care how much his spiritual power had recovered, so he couldn't wait to increase the output of his spiritual energy again, and controlled the two small balls to rotate around each other's center points in the expected way.

"Hurry up, hurry up. ”

Xiao Yu excitedly controlled the aura in his hand, and stared at the two small black and white balls that were spinning rapidly in the Dan furnace with an excited face, watching them approach each other at a slow pace.

And so a quarter of an hour passed ...

"Boom... ”

Suddenly, a deafening explosion suddenly came out from the Huanyun Refining Heaven Furnace, and the originally tightly covered furnace lid was also shaken out by the impact of the explosion, and Xiao Yu, as the leader of all this, was also swept away by the rolling heat wave leaking inside and outside the furnace.

"Fried... Fryer?"

Facing this scene in front of him, Xiao Yu's first thought was the phenomenon of the explosion furnace that often occurs in the alchemy world, but it was the first time he had experienced such a thing since he came into contact with alchemy.

Xiao Yu looked at the Huanyun Refining Heavenly Furnace not far away, looked at the billowing smoke and dust generated by its explosion, and looked at the flames that had been extinguished inside, and couldn't help but feel a little lost in his heart.

"When... ”

A moment later, the sound of metal clashing pulled him out of shock, but it didn't make him feel any better.

Because, the reason why this sound came was only because the lid of the furnace that had been blown away fell back again, and it hit the black smoke of the Dan stove without obliqueness.

"Hey... ”

After a long time, Xiao Yu still sighed, and then he slowly got up like a deflated ball, and walked towards the Huanyun Refining Heavenly Furnace step by step.

"It seems that I still hold it up, I thought I was talented, but the reality slapped me hard... ”

"I still want to save some herbs and make my own food, but I can't steal the chicken and eat a handful of rice, now it's okay, let's start again!"

In this way, Xiao Yu moved his steps and walked with difficulty to the place where the Huanyun Refining Heavenly Furnace was originally located, and the Dan Furnace also returned to the void again because of Xiao Yu's loss of strength.

Seeing the land under my feet, all that was left was the rubble and scorched earth that had been baked black by the high temperature, and in addition, there was...

"Hey, what is this?"

In an instant, a small black and white ball suddenly broke into Xiao Yu's sight, and it also made him see a faint glimmer of hope in his frustration.

As soon as the words fell, Xiao Yu hurriedly grabbed the small ball of different colors in his hand, and put it under his nose with excitement and sniffed it.

Suddenly, a strong herbal fragrance suddenly penetrated Xiao Yu's nostrils, and this little medicinal power actually made his spirit and spirit lift.

"Success... It's done?"
