A thick sense of frustration surged into Yang Yu's heart.

It is equivalent to saying that this time, he has refined nearly a hundred medicinal materials, although there are still many such medicinal materials in the alchemy room, but he can't help but toss like this.

It can be said that the losses are huge.

"I don't believe it, this little elixir can become an obstacle to my progress!"

Yang Yu had the momentum of not admitting defeat, and after a little rest, he started the next alchemy.

After another four hours, Yang Yu successfully refined the medicinal materials of the Qingling Pill, and after a little rest, he began the final step of Chengdan.

This time to refine medicinal materials, perhaps because of the experience of the last time, the number of damaged medicinal materials has been reduced by half.

This kind of achievement can be described as a rapid progress, even if it is an alchemist with sophisticated means, he will be amazed by this, and it is not easy to make a face.

"Whew!"

His methods became more and more skilled, and more than a dozen kinds of medicinal materials and powders were quickly thrown into the Dan Furnace by him, and at the same time, the power of his soul filled the entire Dan Furnace, and any small changes were all visible to him.

Even within the elixir, the neutralization of the medicinal properties and the smelting progress of the flame were carefully controlled by him.

If you fail once, you must avoid the reason for the last failure the second time, otherwise, it will be difficult to succeed this time.

He believes that the first failure of Cheng Dan is that he did not pay attention to the internal structure of the pill, otherwise it would be easy to become a Dan.

Inside the elixir, particles are connected and collided with each other, and a trace of medicinal properties is squeezed and collided inside the elixir, and under the smelting and compression of the flame, it gradually becomes peaceful.

"There should be one last step left, compressed into Dan. ”

As soon as he thought of this, he output a large amount of soul power, including all the fist-sized pills, and then used his perverted soul power to compress the pills and make them start to shrink.

Under the compression of soul power, the elixir suddenly became smaller, and finally gradually stayed the size of an egg. The medicinal power inside also became violent at this time.

Yang Yu carefully sensed that after a long time, the medicinal power inside returned to calm.

"Good. It's almost a success!"

Yang Yu knew that once the pill became the size of a thumb, the medicinal effect could be completely sealed inside, so that it could be regarded as a complete pill.

"Give me Cheng Dan!"

He whispered in his heart, at this time. He compressed the elixir again, hoping to compress it to the size of his thumb.

"Peng!"

However, as soon as his soul power began to compress, the violent medicinal power inside the elixir suddenly exploded like a wild horse on the loose.

"Oh, mom, why did you fail again?" Yang Yu smiled bitterly in his heart.

At this time, Yang Yu didn't dare to act rashly, it seems that he still hasn't found the common reason for the failure twice. Even if you act rashly, you can't escape the end of failure.

He sank his mind into one side, put all the details back aside, and then compared them with his own refining process, but he didn't find anything wrong.

"Could it be that there is something wrong with this Dan Fang?"

Yang Yu couldn't help but start to wonder.

The method of refining medicine is not bad at all, even the process is completely in accordance with what Dan Fang said, step-by-step refining, but why does he fail repeatedly?

Yang Yu couldn't figure this out.

He could only suspect that there was something wrong with Dan Fang. Otherwise, why would he fail repeatedly? He thought he didn't make any mistakes, but what about this failure?

At this time, he temporarily gave up the process of alchemy. Replay what Yun Heng said before in his mind.

"By the way, why did I say I failed? It turns out that the reason is here!" At this time, Yang Yu suddenly felt a little embarrassed.

When he first taught Yang Yu the common sense of alchemy, Yun Heng said that there were two necessary conditions for becoming an alchemist.

One. It is that the martial artist must cultivate the power of fire.

The second is that in the divine power, there is a trace of wood attribute essence, and it is also necessary to use the wood attribute divine power throughout the process of becoming a dan, and there is no trace of it.

Now, he can be considered to have found the reason.

When he was Cheng Dan, he didn't add the wood attribute divine power, so it's no wonder that he failed.

The embarrassment on his face was naturally because he suspected that there was something wrong with Dan Fang before.

"Go on!"

This time, it only took him two hours to refine more than a dozen kinds of medicinal materials, and the process was more proficient, and his mastery of heat and medicinal properties was also more skilled.

This time, he only destroyed more than twenty medicinal herbs, and the success rate increased exponentially.

In this way, he only failed once per medicinal herb, and this kind of improvement made even many alchemists who had been famous for many years feel ashamed.

"This time, it must be successful!"

Yang Yu clenched his fists and said secretly in his heart, and then, the medicinal powder of the Qingling Pill was calmly and orderly thrown into the Dan furnace, and then, the soul power and the wood attribute divine power also entered the Dan furnace together at this time.

Soon, a blue-green elixir prototype was successfully refined.

"Compress!"

He drank in his heart, and then the soul power compressed the elixir, and this time it was surprisingly smooth, and the elixir quickly became the size of an egg.

Yang Yu was ecstatic in his heart, but he didn't dare to relax at all.

"Compress again!"

He suddenly let out a loud cry in his heart, and then all the soul power, including the elixir, compressed it fiercely, because of the mixed with the divine power of the wood attribute, the medicinal properties inside the elixir slowly became gentler.

After another ten or so minutes of smelting, an elixir the size of a thumb was finally formed.

The rich danxiang was also all over the alchemy room at this time.

Yang Yu's face showed a smile of relief, this was his first alchemy success, and the joy of this success made him feel like a fluttering immortal.

A deep feeling of fatigue surged over his body, making him feel a little collapsed.

In the future, he will also be able to tell others with honor that I am a true alchemist.

After more than a hundred failed laughs, a real elixir finally succeeded.

Yang Yu slowly stopped the release of divine power, and collected the soul power as well, the flame in the Dan furnace gradually extinguished, and the temperature quickly dropped.

He stretched out his hand, and the blue-green elixir, which was still warm, flew into his palm.

Yang Yu felt the aroma of the pill up close, observed the surface of the pill, and found that the surface of the pill occasionally had some textured ravines, but overall, it was still very warm and smooth.

This was the first elixir he had refined, and it was of great significance.

Compared with the pills that Yun Heng had refined before, Yang Yu's pill was undoubtedly a bit of a trivial, after all, he had refined one alone, while Yun Heng was refining thousands of pills at the same time.

However, when he thought that Yun Heng had that kind of realm, he was also relieved.

He secretly made an oath that he would surpass Yun Heng in the future! )
