"Then there is no other medicine in this world that can save my sister's eyes?" Long Yun asked anxiously.

"Don't worry, although the purple jade cicada is poisonous, it can be resolved. ”

"Oh, how to resolve it?" asked Long Yun eagerly.

Nangong Yun said: "You can add several detoxifying medicinal materials, together with the purple jade cicada wei, to refine a kind of elixir, called 'Golden Eye Pill'." Give this pill to your sister to restore her eyes without any side effects. ”

After speaking, Nangong Yun told Long Yun all the other medicinal materials needed, but fortunately, the rest of the medicinal materials were in that ring.

Now all that "Purple Jade Cicada Wei" is needed to refine the elixir that heals my sister.

Long Yun was extremely excited at the moment. thanked Nangong Yun repeatedly, for so many years, he has been going to the deep mountains, just to find the "purple jade cicada wei" that can cure his sister's eyes. His mother also died trying to find the herb.

But now he knew that the herb would kill his sister, and at this moment he was a little glad that he didn't find the "purple jade cicada wei" earlier, if so, he would have harmed his sister.

Although Long Yun hadn't found the "Purple Jade Cicada Grass" yet, he was much more confident than before. He felt that it was only a matter of time before he found the herb.

Long Yun thanked Nangong Yun repeatedly.

Seeing that Long Yun cared so much about his sister, Nangong Yun's favor for him increased a little. Because from this point, it can be seen that the young man in front of him is definitely not a heartless person.

"Don't be so happy. ”

Seeing that Long Yun seemed to be so happy that he forgot his form, Nangong Yun hurriedly reminded.

"Is there anything else to pay attention to?" Long Yun asked.

Nangong Yun said: "Although you now know the recipe for refining the 'Golden Eye Pill', it is not so easy to refine the pill successfully. At the very least, you have to become a five-rank Dan master to be possible. ”

Five Rank Dan Master?Long Yun was a little surprised.

He had heard of the classification of Dan Masters, and there were also Dan Masters in the Beast Hunting Alliance, but he heard that the highest level there was only a Triple Rank Dan Master, and it was still an old man who had been alchemizing for decades and had just advanced to a Triple Rank Dan Master.

But now Nangong Yun said that at least a five-grade Dan master can refine this Dan. This made Long Yun a little disheartened, he thought, if he wants to be promoted to the Fifth Rank Dan Master, wouldn't he have to be at least old enough to be too old, and what is the point of curing his sister's eyes at that time!

Nangong Yun seemed to have guessed Long Yun's thoughts, and said: "You don't have to worry too much, as long as you practice hard, plus the Dan Dao I passed on to you, it won't be long before this five-grade Dan Master." ”

Listening to Nangong Yun's words, Long Yun suddenly became more energetic again, and hurriedly begged Nangong Yun to pass on his Dan Dao.

......

Since then.

Long Yun was in this ancient tomb, and he and Nangong Yun practiced the way of alchemy and the method of arranging the array.

With this living fairy-like fairy teaching him, Long Yun's progress was rapid.

During this time, from Nangong Yun, Long Yun learned a lot about Dan Dao.

The elixirs in this world are divided into nine grades. And on top of these nine products, there is another one, which is called the elixir.

The difficulty of refining each grade of elixir is different, the higher the grade, the greater the difficulty, and the lower the success rate.

People judge the level of a Dan Master by how many grades of pills he can refine, and if he can refine a three-grade pill, he is a three-grade alchemist, and so on.

And the same pill is also divided into advantages and disadvantages.

The difference in quality is divided into four grades, inferior grades, medium grades, superior grades, and absolute grades.

Most of the pills refined by ordinary people are medium, and the best ones can be said to be rare, and the absolute pills are all available but not sought.

The efficacy of different grades of pills varies greatly, especially the ultimate pills, the efficacy of which can be multiplied, and the value is hundreds of times higher than that of ordinary grades.

This elixir is a good thing!

Cultivators in the world can't do without this elixir.

For example, when Long Yun came out to practice, the "Bigu Pill" given to him by Xia Qingyan was the lowest level of elixir, which can make people satisfy their hunger without eating, which can be described as very practical.

When Xia Qingyan first accepted Su Yusheng and Long Yun as apprentices, he gave Su Yusheng a "marrow cleansing pill", which is a second-grade elixir that can wash away impurities in people's bodies and make the aura in people's bodies more pure.

And the "Nine Turns Soul Rejuvenation Pill" that Nangong Yun said could save her was a kind of elixir, so it was extremely cumbersome to make.

If you want to refine a "Nine Turns Soul Rejuvenation Pill", not only is it difficult to collect materials, but the refining method is also cumbersome.

You have to refine a few other pills first. Then, several of the elixirs and other precious materials were refined together for several months.

And in the process of refining, you must use your divine sense to constantly perceive the changes in the elixir, adjust the size of the fire at any time, and add some auxiliary materials at any time according to the situation.

And to input their own aura, stabilize the medicinal properties, the aura is insufficient, the effect of the medicine will scatter and escape, unable to lock the effect in the elixir, that is a "dead medicine", completely useless; the aura is too large, the impurities in the elixir are not easy to evaporate, it is easy to fry.

Therefore, to refine that medicine, you must concentrate your mental power very much, and you can't relax at any moment. And the spiritual power is sufficient, and you must have enough proficiency and experience in the way of alchemy, as well as extremely strong control ability and adaptability, it is possible to give it a try.

Even so, even if you don't make any mistakes, success or failure depends on God's face!

So indeed, as Nangong Yun said, if you want to make this elixir, it can be described as "difficult to reach the sky"!

Not to mention anything else, the seven kinds of rare medicinal materials that are still lacking in refining the "Nine Turns Soul Rejuvenation Pill" are all available but not sought, and they can only be encountered by luck.

Nangong Yun didn't collect it for nine lifetimes, let alone today's Long Yun.

Besides, if you want to refine the elixir, you must reach the level of an alchemist above the ninth grade.

And in the entire Beast Hunting Alliance, the highest alchemist is only a third-grade alchemist, and even if it is the entire continent, it may not be possible to find a nine-rank Dan master. And it was because they were all poor all their lives that they reached that achievement.

Although Long Yun is making rapid progress now, he is only limited to these low-level pills, and if he goes up, the difficulty of each grade increases exponentially, and if he wants to rise to the ninth grade, it must not be so simple.

Therefore, it is conceivable how arduous the task of saving Nangong Yun should be. With Long Yun's current cognition, it is almost impossible to complete.

But he has made up his mind, no matter how difficult it is, he has to give it a try, after all, Nangong Yun is also his nominal wife, and he doesn't want to see her empty in this ancient tomb.

Long Yun now seemed to understand Nangong Yun's strange behavior.

Nangong Yun has a reason why he has to be married to him.

The task of resurrecting her is not something that can be completed in a year or two years, it may take a lifetime of hard work, and it may not be possible to do what you want.
