Immortal cultivation starts with copying.

Cai Lingyun first refined a batch of other elixirs, which were top-level seventh-grade elixirs.

As for what kind of elixir it was, Cai Lingyun did not say, but Chen Yunhao kept guessing but still could not figure it out.

His level is still far from the seventh level of refining. Although he has collected some pill recipes, there are so many kinds of elixirs in this world that it is impossible for him to collect them all.

So it was normal that there were elixirs that he didn't know about, but he did have an impression of most of them, so he could probably guess what they were used for.

It was extremely difficult and complicated for Cai Lingyun to refine this batch of seventh-level elixirs. He did it purely for practice and to master the feel for the next step of refining.

It took six or seven hours to refine this batch of pills, and Chen Yunhao was fascinated watching from the side.

After all, he is someone who is about to be promoted to a master of alchemy. His techniques, experience in handling emergencies, and reactions are beyond the reach of ordinary people.

Without the simultaneous explanation of the alchemy master, he couldn't understand some of the deeper things, but the parts he could understand had already benefited him a lot.

He felt quite satisfied at this point, but next he would witness the entire process of an alchemy master's promotion, which was what made everyone envious.

But no matter how envious they are, others cannot learn from him, because Chen Yunhao did contribute the most, which was equivalent to saving Cai Lingyun's life, and this is what he deserves.

After refining this batch of pills, Cai Lingyun took a whole day to regulate his breathing before he was ready to start refining the Shengxi Pill.

From this moment on, Chen Yunhao didn't even dare to blink, and didn't miss any link.

To refine the eighth-level elixir, Cai Lingyun used a different refining technique. This was a more advanced technique that he had never used before.

The refining techniques are different according to the different schools, and these are the unique secret skills of each school.

Chen Yunhao's alchemy skills are relatively common, and he does not have the unique skills that Cai Lingyun has, so his room for improvement in alchemy is limited.

He could only wait until he had the chance to encounter the right alchemy technique in the future. From Cai Lingyun, he could only get a superficial understanding and could not steal his skills.

Of course, it was impossible for him to become a disciple of someone of the same level of cultivation.

From the placement of the elixirs to the order in which they are prepared, all the details before refining the elixir are very particular.

He didn't pay much attention to this aspect in the past, and just thought that it would be fine to put it in the place that was most convenient for him.

But he never thought there was such a difference. It was only after this on-site observation that he realized it.

Refining the eighth-level elixir is a very long process. After several hours, Chen Yunhao only felt like a moment had passed.

"Pity……!"

Chen Yunhao shook his head secretly. After seven or eight hours, the result was no success.

Cai Lingyun is indeed extremely talented in alchemy and is very good at refining and purifying.

Therefore, there are almost no problems with the first and second steps. The problem arises in the third step, which is commonly known as dividing the elixir.

In general, Cai Lingyun was a little too hasty. He wanted to prove his ability.

But in the end, he underestimated the difficulty of the eighth-level elixir. He wanted to divide it into five pills at once, but overestimated his control ability and ultimately failed to make any one pill.

As the saying goes, a single move can affect the entire body. The five elixir prototypes that had just formed shattered one by one in front of Chen Yunhao's eyes, and finally turned into wisps of green smoke and disappeared.

Cai Lingyun had no expression on his face. He simply stopped what he was doing and closed his eyes, as if he was meditating to recover his strength.

In fact, Cai Lingyun was reviewing the entire refining process. After two hours, he knew where he went wrong and how to deal with it.

Then he started refining again, and this time Cai Lingyun was more cautious.

This is an excellent quality that a qualified alchemist possesses. He will not be blindly arrogant, but will only learn lessons from failure.

Chen Yunhao was a little fascinated watching from the side. Look at Master Cai's technique, the speed of purification is really extraordinary, it's hard not to admit defeat.

Soon after a few hours, it was time to divide the pills. This time, Cai Lingyun learned his lesson and only divided two pills. He did not mention the quantity, but only mentioned the success rate.

First solve the problem of success, then solve the problem of quantity. As long as you practice makes perfect, the success rate will naturally be high.

Two unformed elixirs were slowly turning in the furnace. Cai Lingyun's hands were like butterflies flying through flowers, chanting various spells.

He injected invisible spiritual power into the two spiritual pills.

Gradually, the two elixirs shrank little by little and became more solid. Lines of elixir patterns began to appear, just like array patterns, which were particularly complicated.

The grade of the elixir can be determined from the patterns on it. The higher the grade of the elixir, the more complex and mysterious the patterns are.

If you look at this kind of Danwen for a long time, it feels like the way of heaven, which is unpredictable. To put it bluntly, it is a manifestation of the way of heaven.

The higher the level of the elixir, the less than 70% of the medicinal power it exhibits.

The remaining 30% of the medicinal power depends entirely on the alchemist's refining techniques and his understanding of the laws of nature, and whether he can integrate it into the elixir.

This directly determines the quality of the elixir. Anyway, as a person who is half knowledgeable, Chen Yunhao intuitively feels that the elixir should be successful this time.

He couldn't help but sigh in his heart that talent is something that is really beyond one's control. No matter how hard a person without talent tries, he will still be a little worse off.

Cai Lingyun is a person with a strong talent for alchemy. He has only tried twice to achieve such an important goal as to advance to the master of alchemy.

If it were an ordinary alchemist, it would be impossible to succeed without failing dozens of times.

Chen Yunhao's alchemy skills are based on repeated refining. Because he has a floating island that can delay time in disguise, and he has unlimited resources, it is impossible for the alchemy skills to fail.

But other people don't have the same cheating methods as him. Anyone who can reach the master or grandmaster level is a person with extremely great talent.

Chen Yunhao was very convinced of this, so he came here to humbly seek advice.

Sure enough, after the pills were divided, making them became much easier. After just over two hours, two Shengxi Pills were successfully made.

These two life-giving pills are green in color, emitting a strong vitality, and each one is only the size of a thumb.

Chen Yunhao looked at the two Shengxi Pills with a very astonished look. This was the first time he saw an eighth-level elixir at such a close distance.

The surging medicinal power of the elixir even danced gently in Cai Lingyun's hands, appearing to be full of spirituality. This is the real elixir.

But Cai Lingyun just looked at it carefully for a few times, sighed, shook his head in disappointment, and felt very dissatisfied.

Chen Yunhao didn't care whether Cai Lingyun was satisfied or not. He only knew that from this moment on, Cai Lingyun was the master of alchemy.
