The ice blue flame rose in the medicine cauldron. Ling Yu's eyes also reflected the ice blue flame with its teeth and claws. He stared at the two essence powders slowly fused together in the flames.

The soul stream in my mind also swept out quietly.

With the assistance of soul perception and soul flow, Ling Yu's mind slowly calmed down from tension. He carefully controlled Hai Yan's cold fire to prompt the two essence powders to gradually gradually at a slow speed.

Fusion.

The subtle collision sounds generated by the fusion of the two medicinal materials also spread from the medicine cauldron, and occasionally sparks burst out, and the magazines in the two essence powders also became more and more as the sparks sputtered.

Thin, after a moment, the last bit of impurities that were waiting for was lifted by Haiyan's cold fire, and the two essence powders were finally merged together.

The faint fragrance also spreads from the top cover of the medicine cauldron, and instantly filled the entire cultivation room!

"The next is the third material." Ling Yu breathed a sigh of relief. The first fusion was quite smooth. There were several dangers in Shunran, but in the end, Ling Yu is now outstanding.

The source fire control force is gone.

With a move of his finger, the third pink essence powder was put into the medicine cauldron. Time passed slowly, and two hours had passed in the practice room, and Ling Yu, who was sitting cross-legged,

At this time, sweat also slid down on her little face, her lips slightly opened, and a slight panting sound slowly spread.

I want to gradually integrate the medicinal materials for refining the fourth-grade spiritual pills together, which is more complex and more costly than refining the third-grade spiritual pills.

Fortunately, after Ling Yu's nearly three hours of hard work, the more than 20 medicinal powders needed to refine Yan Dan were also smoothly integrated. Next, the last spirit beast essence was fused into it, and then

After hearing the words through the source fire, you can be completely refined successfully.

As for the next step, Ling Yu's face slowly became solemn, and there was a solemn look in his dark eyes. Obviously, this last step of fusion still has something to do with Ling Yu.

A little pressure!

"Yan Lingbeast, the 218th spiritual beast in the Earth-level spirit beast ranking list, never changes from birth to the end of life, like a cute little rabbit, making people feel like

I couldn't help but want to hug me..." Ling Yu looked at the spirit beast spirit floating on the left hand, which was full of pink aura, but there was a surprise in his heart.

This kind of Yan Ling Beast is more rare in the spirit world than the Thunder Tiger monster, and its cute appearance from beginning to end is even more difficult to detect. To be honest, if you want to successfully capture Yan Ling Beast,

It is still difficult to ascend to heaven, because they can always detect the dangers around them from ten thousand meters away and escape early.

Any kind of spiritual beast has a talented secret technique, just like the Thunder Tiger Monster. It is born to be able to control the power of thunder and the strange black flame that the Netherworld Bird is good at, and the Yan Lingbeast is good at

In escaping and hiding breath.

Therefore, it is quite difficult for those rich and powerful people to invite a fourth-grade alchemist to refine a Dingyan pill for him. The materials that need to be refined can make him feel headache.

What's more, it took a lot of effort to find a Yan Ling Beast, and it also had to bear the risk of refining failure. Even the fifth and sixth grade alchemists were unwilling to take such orders easily, although

If the refining fails, destroying the materials of a medicine cauldron will not involve the responsibility of the alchemist, but the probability of failure can make those high-level alchemists lose face.

Therefore, if you want to refine Yan Dan, it is particularly difficult to estimate the value once you successfully refine it. After all, as long as you have the finished Dingyan Dan in your hand, the person who wants to buy it will

There will be no risk that will be taken anymore, but the price is a bit too high.

"Oh..." Ling Yu's mind flipped over and couldn't help but sigh. Even the fifth-grade alchemist could not guarantee the success of refining. His third-grade alchemist wanted to successfully refine the fourth-grade Dingyan

Dan, that's really harder than climbing to the sky...

From the fusion of monster inner elixirs, the difficulty of low-level monster inner elixirs to top-level monster inner elixirs has gradually increased, but the increase did not exceed Ling Yu's limit, and this was suspended by him

The spirit beast spirit glowing in front of him has improved qualitatively.

"I have to treat the dead horse as a living horse!" Ling Yu smiled bitterly. Anyway, with four sets of medicinal materials, as long as you can successfully refine a Dingyan Pill, you can get the cost back. This is what he thought in his heart

Thinking of the tense feeling I felt relaxed when I was refined.

He bounced his fingers at the pink essence and threw it into the medicine cauldron.

As soon as the spirit of Yan Lingbeast entered the medicine cauldron, Hai Yan cold fire in the medicine cauldron suddenly became irritable, and the more than 20 light red and viscous substances fused by Ling Yu also had violent collision sounds.

Swipe out.

For a moment, the ice blue flames filled the medicine cauldron like boiling, and a stream of cold and hot energy instantly swept the cultivation room.

"Suppress, suppress..." Ling Yu had only one thought in his mind, which was to suppress the irritable Hai Yan Lenghuo. Although he was a little prepared for this early, Ling Yu saw what happened,

There was also a look of panic.

Ling Yu's face was solemn, his hands were stretched into the edge of the hole under the medicine cauldron, and the soul perception in his eyebrows swept out without reservation, suppressing the irritable Hai Yan Lenghuo hard.

Now Ling Yu is becoming more and more skilled in controlling the soul perception. After a moment of hard work, the restless flames slowly become calm.

Seeing the light red viscous substance gradually approaching the spirit of Yan Ling Beast, Ling Yu quietly breathed a sigh of relief. As long as there was no mistake in this process, it would increase the chance of success.

As the two substances gradually approached, the spirit beast spirit also changed a little. At the edge of the spirit, the pink spiritual light jumped, and sometimes a ray of spiritual light swept away towards the viscous substance.

There were also dense beads of sweat appearing on Ling Yu's forehead, and then flowing down his cheeks. Sweat also poured in from his dark eyes. The squeaking sweat made Ling Yu's eyes narrow slightly, but

Ling Yu did not dare to be careless at all, and continued to promote the integration of the two carefully.

The soul flow in the eyebrows will also open to the maximum extent, just like the rushing Yellow River, whistling into the medicine cauldron. At the same time, Ling Yu's eyes slowly closed, and his mind entered the pyramid square.

, There, a huge light curtain condensed, and the picture was like a lively bird, showing all the extremely small fluctuations.

"Fortunately, I have mastered this soul stream, otherwise, I'd probably have failed because of the mistake." Ling Yu sighed.

Under Ling Yu's persistent control, the pink viscous substance and the Yan Lingbeast spirit finally showed signs of fusion. The medicine cauldron also transformed into three colors, light red sticky.

The thick substance occupies half, and the pink essence of the Yan Lingbeast occupies half, and the ice-blue flames are surrounded by ice-blue flames.

Ling Yu dared not carry it at all. All his abilities were injected into the medicine cauldron without any reservation, and the mental power of sensing the surrounding aura fluctuations was also added to this army.

After half an hour of refining at this high concentration, a pink elixir appeared faintly as the ice blue flames rolled, but the color on the surface was dull and uneven.

"The prototype spirit pill..." Ling Yu couldn't help but breathe a sigh of relief. As long as it is purified, the Dingyan pill can be completely refined!

However, just as Ling Yu's nervousness was relaxing, the flames in the medicine cauldron suddenly stagnated, and a feeling of being unable to do so slowly spread in Ling Yu's mind.

The progress of the prototype spiritual pill in the medicine cauldron that removed a trace of impurities also slowed down extremely slowly. Ling Yu frowned slightly. This feeling was not the first time he noticed it. It was when he was refining the third-grade spiritual pill.

There was a faint fluctuation, but it was not as strong as it was at this time.

"Is it because of Hai Yan's cold fire?" Ling Yu's eyes also had doubts flashed by.

"If it is because of the flame, how did the alchemists on the continent who did not control the source fire successfully refine high-grade spiritual pills?" Ling Yu's doubts gradually spread.

"Source fire is different from the flames converted by animal fire or human practice of fire attributes. If you want to use source fire to refine elixirs, although the quality is higher than that of ordinary flames, there is also a boundary between Zi fire and Eye Fire.

It seems that if you want him to successfully enter the fourth level alchemist, you can find a source of fire for him again." Mixiu opened his closed eyes slightly and looked at the reflected scene on the screen.

, a slow way.

"Bang!"

While Ling Yu was puzzled, a dull sound suddenly came out of the medicine cauldron. The ice-blue flames exploded and rushed out of the medicine cauldron, and then all the debris in the cultivation room were given to

Burned out.

Ling Yu suddenly opened his eyes and stared blankly at the medicinal materials that had turned into a pool of ashes at the bottom of the medicine cauldron. His face became extremely ugly. For a moment, various reasons for failure flashed out in his mind.
Chapter completed!
