In this world, there are many geniuses, and Fang Yun has sighed more than once about the strength of his predecessors, and lamented those amazing discoveries and great creations.

To complete the Void Condensation Pill, when it was just beginning, it should be to complete the lost elixir recipe, so that the ancient powerful elixir can reappear in the world.

However, in fact, in the later stage, the completed Void Condensation Dan Fang was already very different from the Gu Dan Fang.

To be precise, the ancients once had such a pill, and then, the world changed, this pill recipe was lost, and after the descendants got the lost pill, they pondered its principle and reproduced the pill prescription according to its pharmacology.

Because the environment in ancient times is different from today, there will be a large deviation in the efficacy of the elixir, so this kind of complement has been changed beyond recognition in the end, and it is basically a new elixir.

However, what is different from the new creation is that there is an ancient recipe in front of it, which announces the name and efficacy of the elixir, and future generations only need to follow the map.

It took more than an hour for Fang Yun to finish reading the codex of his predecessors one by one, and then began to close his eyes and meditate, digesting what he had just learned in his heart.

I have to say that over the years, the research of Xike Medicine God has been pushed to the extreme by various generations of medicine gods, and the pharmacology in all aspects has almost taken shape, and in the hands of Binghe Medicine God, these pharmacology have been put into one furnace and have become a very perfect Danfang.

But even so, the refinement of this Dan is still a waste Dan.

So, what's the problem?

Fang Yun did not pharmacologically analyze and study the current Dan prescription of the Void Condensation Pill.

Because Fang Yun thought that after so many years of research, these technologies should have matured a long time ago.

The possibilities that you can think of will definitely be thought of by others, and the problems that you can find can also be discovered by those genius medicine gods.

Fang Yun didn't feel that he was unique in the world.

In other words, Fang Yun thought in his heart that as far as the Dan prescription was concerned, there were not too many problems with the current prescription.

Thinking about it from another angle, could Fang Yun come to a conclusion, that is, with the current elixir growth environment, it might not be possible to grow a suitable elixir for refining the Void Condensation Pill at all.

If this conclusion is true, then there is no point in repairing this ancient Danfang.

Fang Yun quickly summarized the pharmacological analysis of Xike and Binghe in his mind, and then roughly had some ideas in his heart, judging from some of the ancient pill formulas that Xike had already cracked, in the current environment, nine times out of ten, the Void Condensation Pill could not be refined at all.

When he thought of this, Fang Yun's heart suddenly moved, and a flash of inspiration flashed in his mind, and he grasped the key to the problem.

All the research of later generations is basically based on two blueprints.

One is the existing and relatively complete ancient Danfang, and the other is the research codex of Sike, especially the latter, which is the original research material recognized by later generations, and it took Sike a long time to study the ancient script, which gradually deciphered the ancient script and formed the existing Danfang.

Fang Yunfei quickly thought about it and found a problem, that is, future generations would basically not question Xike's decipherment of ancient characters, and moreover, Xike's medicine god was synonymous with profound knowledge and knowledge of the ancient and modern in his time, and no one doubted the Danfang he deciphered.

Then, Fang Yun sensitively grasped the crux of the problem.

Danfang, especially high-grade Danfang, every word and sentence has a special important role, and the Danfang deciphered by Xike, as long as one word is wrong, there may be a great directional error.

In Fang Yun's mind, a panoramic photo of Gu Danfang appeared, and at the same time, it also reflected Xi Ke's deciphered text.

If there is any difference from other alchemists, or rather, Fang Yun's greatest advantage is because Fang Yun is a true scholar of language and writing.

This is not Fang Yun's self-styled, but an officially recognized university scholar by Tima.

I have to say that Sico is really a particularly powerful scholar.

Gu Danfang and the Dan Fang deciphered by Xike were so compared, and with Fang Yun's level, no obvious errors could be found.

In other words, the decipherment degree of Xike's Danfang has reached at least ninety percent or more.

Even if there are some subtle mistakes, it is the opinion of the benevolent and the wise.

Thinking about it quickly, Fang Yun took out the research codex of the Ice River Medicine God, and compared the three together.

When he only compared the Xike Codex and the Gu Dan Fang, Fang Yun found no obvious errors.

When he only compared the Xike Codex with the Glacier Codex, Fang Yun still failed to find an obvious error.

However, when Fang Yun directly compared the Binghe Codex with Gu Danfang, he suddenly found at least five or more subtle changes, three of which were crucial.

Studying the pharmacology of the Ice River Codex alone, these three changes are appropriate and reasonable, but if these three changes are put into the Gu Dan formula, it will inevitably trigger a series of chemical reactions, and the final result will inevitably lead to the appearance of waste Dan.

This discovery surprised Fang Yun quite a bit.

How did this happen?

Fang Yun put Gu Danfang and the two codex together and studied them carefully, but he quickly found the crux of the problem.

There are many reasons for this, but the main one is that you are not familiar with ancient languages, and it involves a variety of factors such as measurements, and it is difficult for those who are not particularly familiar with ancient characters to find anomalies.

And what's interesting is that this kind of change is still a gradual process, and I'm afraid that even the Ice River Medicine God will be difficult to find some mistakes in itself.

For example, a special kind of Yuan Magnetic Spirit Earth is used in the Gu Dan formula, and its dosage is marked as Weiang.

Regarding the word Weiang, Sico's interpretation is not wrong, the ancient unit of measurement of Weiang is about equivalent to a millimeter unit.

Here, Sico uses the millimeter as a unit of measurement.

But in fact, as far as Fang Yun knew, Wei Ang and Hao Biao were not completely identical, they could only be said to be roughly similar, in fact, there was not much difference between the two, and it had no effect at all when they were taken to alchemy.

But the problem is that the unit of measurement of the millimeter standard is also the unit of measurement 10,000 years ago, after so many years of changes, calibration, the unit of measurement of the millimeter standard has been very different from before, and even the millimeter standard of the era in which Sico is located is not clear.

In the end, among the pills of the Ice River Medicine God, the amount of Yuan Magnetic Spirit Earth was also a millimeter.

As a scholar of language and writing, Fang Yun can tell the Ice River Medicine God very responsibly, "Your formula is overdosed. ”

This is one of them, and there are several similar ones.

These different dosages will inevitably lead to different pharmacology, so in the end, there is a lot of room for improvement in the Danfang of the Ice River Medicine God.

With a move in his heart, Fang Yun continued to compare the ancient recipes and mark the obvious doubts.

Find the problem, next, it is time to really test Fang Yun's level, every change has a great impact on the pharmacology of Dan Fang, which requires a lot of time to re-deduce.

Fortunately, that Ice River Medicine God was quite generous, and he actually put his deduction process completely in front of Fang Yun, which saved Fang Yun a lot of trouble.

Among the elixirs of the Ice River Medicine God, most of the things could be borrowed directly, so Fang Yun didn't have to bother thinking about it anymore.

Unconsciously, Fang Yun had already picked up the pen and kept entering his modified Danfang pharmacology on the computer panel.

Several problematic areas were marked out by Fang Yun, modified one by one, and then, according to pharmacology, the Danfang in Fang Yun's hand was gradually taking shape.

However, before Fang Yun could completely complete the pharmacological inference, suddenly, Fang Yun discovered a new problem, that is, unconsciously, he had come to the old path of the Xike Medicine God, that is to say, if he continued to extrapolate according to this line of thought, there would only be one result in the end, that is, he couldn't even refine the waste pill.

After all, the Dan prescription of the Xike Medicine God has a very high degree of reduction, and Xike's knowledge is also quite profound, what Xike can't do, Fang Yun is afraid that it will be difficult to do.

Putting down the pen in his hand, without continuing to calculate, Fang Yun fell into a long exam.

For a long time, Fang Yun picked up the Codex of the Glacier Medicine God again, and seriously experienced the Glacier Medicine God's pill formula.

At this moment, Fang Yun sighed again in his heart, this Ice River Medicine God was indeed a real strongman, these places seemed to be a little different from the Gu Dan Fang, but, on the whole, it was already able to refine into a waste pill.

If it is not modified, the waste pill will not be refined.

However, after Fang Yun's long exam, he already had his own judgment in his heart.

Standing on the shoulders of the two giants, combined with the completion experience of the other Medicine Emperor Medicine Gods, Fang Yun also had his own answer in his heart.
