Chapter 4505: Broad and profound

Although the flame that Lu Shan has shown is very bright, it is almost not very hot. It burns quietly, but it illuminates the third floor of the tower brightly, even if it is modern compared to the earth. Electric lighting is not bad at all.

Lu Shan didn’t waste time, so he just found a place to sit down, first he exchanged the eighteen jade slips that hadn’t been read, and put them on his forehead one by one to read them. Started slowly looking through the memories and feelings...

The strength of his spirit at this moment is so strong that he doesn't even know what kind of realm he has reached. Even if I read 18 jade slips containing huge amounts of information in a row, they didn't even have any side effects.

Looking at the specific content of these jade slips at this moment, it is also extremely fast...

Because the contents recorded in these jade slips were not all words, but contained a variety of information, Lu Shan looked at it at an amazing speed.

It's just that... these jade slips contain too much content, and Lu Shan still needs a long time to read all the content in a jade slip.

But fortunately... many of the basic parts of these jade slips have something in common. As long as you compare them with each other, he doesn't need to read most of the content again. Therefore... read the three in detail. After a jade slip, the remaining browsing speed increased dramatically.

But when it involves some difficult contents, Lu Shan's reading speed will still be greatly reduced. Fortunately, there are so many alchemy books he has come into contact with at the moment, and the contents that cannot be read in this alchemy. If you compare it with the other parts, you can often get a sense of clarity.

Lu Shan found out that it might be the reason for the strength of his soul, and his comprehension seemed to have improved a lot. Originally, when he first came into contact with alchemy, the content was exactly like reading a book, but at this moment, he can easily understand it without much effort. , Even for some particularly difficult problems, he would often study several Dandians at the same time, and he would basically be able to find the problem!

That's it... After more than twenty days have passed in a hurry, Lu Shan has already read the contents of these newly obtained more than twenty alchemy books in his mind, and at the same time... he has also firmly remembered it. , Most of the content is also thoroughly understood.

There are only a few questions left. Although I have a certain understanding, I still have some doubts about whether my understanding is really correct.

However... these problems can't be completely solved by analyzing them in the brain just like this, they still need to be practiced to get the final answer.

Therefore, Lu Shan no longer continued to indulge in the study of alchemy theory, and with a light wave of his hand... he has released a pill furnace that is about half a person high...

This pill furnace was also temporarily borrowed by Lu Shan through Hall Master...It was different from the pill furnace he used before in the examination in the alchemy hall.

The grade of this pill furnace has reached the level of a top-grade treasure, even in the entire alchemy hall, only two pill furnaces are of higher grade than this. If Lu Shan had not had the title of the first alchemy hall, he would really not be able to borrow such a precious alchemy furnace.

After Lu Shan released the pill furnace, he did not rush to start alchemy. Instead, it took nearly an hour to practice the pill furnace for a while. After all dozens of restrictions were released, he began to prepare. Alchemy.

The process of alchemy was quite irritating, but for Lu Shan, who had already developed a keen interest in alchemy, it was quite an interesting experience...

In short, Lu Shan started from the first-level pill, continuously refining and studying... and slowly transformed the knowledge he had just learned from the twenty-odd pill codes into his own abilities.

The first-level pill is no longer difficult for him now. Lu Shan chose three more first-level pill at will and tried them one by one. Each furnace can produce the best quality. The pill comes, the best one...even four three-patterned, two four-patterned...and three five-patterned and one six-patterned pill were refined.

Although he feels that he still has a lot of room for improvement in the first-level pill, even if he can't refine the legendary ten-patterned pill, but...the eight-pattern and nine-patterned pill, he has more After spending some time and studying it, there should still be a chance to refine it.

But Lu Shan didn't want to attack any pill now, just to deal with the difficulties of the Presbyterian Church, naturally there was no need to refine such a high-quality pill.

So... Soon he began to study the refining of the second-level pill.

After trying two furnaces at first, only one top-grade pill with pill pattern appeared in each furnace, and all the rest were only top-grade.

This made him realize that the second-level pill is really much more difficult than the first-level pill... Therefore, he did not rush to try the third-level pill, but through a furnace of repeated experiments, looking for the imperfect refinement. The details are.

Once I found the problem, I checked the contents of the dozens of Dandians in my mind again, and found a solution to the problem...

After refining three furnaces of second-level pill in a row, finally... the sixth furnace of second-level pill, when it was released, all reached the level of the best pill. It's just that... out of the ten pills in this furnace, only two have two patterns, and the rest are all top-quality pills with one pattern.

That's it... After refining seven or eight furnaces, he finally allowed the quality of the second-level pill he refined to stabilize at least at least two grains, but in the end he failed to refine a five-stripe. The highest level of the best pill is only four lines.

Before I knew it, a few days passed again. Lu Shan didn't dare to delay any more time, so he began to refine the third-level pill.

If this continues...every time he raises a level, he will feel that the difficulty of refining will greatly increase, but fortunately, he has already engraved the contents of those dozens of alchemy in his mind, just try to refining one. With two furnaces, you can probably find the source of your problem.

It's just... the speed at which he can refine the best pill is getting slower and slower!

By the time he learned the fifth-level pill, he had to continuously refine nearly twenty furnaces of pill, and finally a top-grade pill with pill pattern appeared.

This made Lu Shan sigh secretly that alchemy is indeed a very profound knowledge...Fortunately, for the first and second levels of pill, the difficulty has risen to a very astonishing level, if it is not because of his powerful spiritual power. , Coupled with the almost instinctive control of the flame, it is almost impossible to refine the best pill!
