Chapter 4505

Although the flame shown by Lushan is very bright, it is almost not very hot. It burns so quietly, but it shines brightly on the third floor of the tower, even compared with the modern electric lighting of the earth.

Lu Shan didn't waste time. He directly found a place to sit down. First, he pasted the 18 jade slips that had not been read on his forehead one by one, and then began to look through his memory and perception slowly

The strength of his spirit at the moment was so strong that he didn't know what level he had reached. Even if I read 18 jade slips containing huge information in a row, I didn't even have any side effects.

At the moment, looking at the specific contents of these jade slips, it is also very fast

Because the contents recorded in these jade slips are not all words, but contain a variety of information. Lu Shan's browsing speed is also quite amazing.

But... These jade slips contain too much content. It still takes Lushan a long time to read all the contents of a jade slip.

However, fortunately... Many basic parts of these jade slips have something in common. As long as they are compared with each other, he can not repeat reading most of the contents. Therefore... After reading the three jade slips in detail, the browsing speed of the rest increases greatly.

However, when it comes to some difficult contents, Lu Shan's reading speed will still be greatly reduced. Fortunately, he has been exposed to a lot of alchemy classics at the moment. For the contents that cannot be read in this alchemy, it can often be suddenly enlightened by referring to other books.

Lu Shan found that it may be the reason why his divine soul is strong, and his understanding seems to have improved a lot. Originally, when he first came into contact with alchemy, he was completely like reading heavenly books. At the moment, he can easily understand it without much effort. Even if it is a particularly difficult problem, he often delves into it by comparing several scriptures at the same time, You can basically find the problem!

In this way... After more than 20 days in a hurry, Lu Shan has read all the contents of these newly obtained more than 20 Dan scriptures in his mind. At the same time... He has also firmly memorized them, and most of the contents have been thoroughly understood.

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

However... These problems can not be completely solved by analyzing them in the brain like this. It still needs practice to get the final answer.

Therefore, Lu Shan no longer indulged in the study of alchemy theory. With a gentle wave of his hand... He has released a pill stove about half a person high

This is also a Dan furnace that Lu Shan borrowed temporarily from hall leader Yu... It's different from the one he used when assessing in the alchemy hall.

The grade of this Dan furnace has reached the level of top-grade treasure. Even in the whole alchemy hall, only two Dan furnaces have a higher grade than this. If Lu Shan had not been the first one in the alchemy hall, he would not have been able to borrow such a precious furnace.

After Lushan released the Dan furnace, he was not in a hurry to start alchemy. Instead, he spent nearly an hour refining the Dan furnace and untied all the dozens of prohibitions before he began to prepare for alchemy.

The process of alchemy is quite impetuous, but for Lushan, who has developed a strong interest in alchemy, it is still a very interesting experience

In short, Lu Shan started from the first-class pill, refining and studying it step by step... And slowly transformed the knowledge he had just learned from the more than 20 Scriptures into his own ability.

Level-1 pills are no more difficult for him now. Lu Shan randomly chose three level-1 pills and tried them one by one. Each furnace can refine the best quality pills, the best one... Even four pills with three stripes, two pills with four stripes... And three pills with five stripes and one pill with six stripes.

Although he feels that he still has a lot of room to improve in the first-class pill. Even if he can't refine the legendary ten grain divine pill, he... He spent more time and studied the top-grade pill of eight and nine patterns. He should still have a chance to refine it.

However, Lu Shan doesn't want to attack any pill God now, just to deal with the difficulties of the elder's hall. Naturally, it's not necessary to refine such high-quality pills.

Therefore... Soon he began to study the refining of secondary pills.

After trying two heats at the beginning, there was only one top-grade pill with Dan pattern in each heat, and all the rest were just top-grade.

This made him realize that the second level pill was much more difficult than the first level pill... Therefore, he was not in a hurry to try the third level pill again, but through repeated experiments, he looked for the details of his imperfect refining.

Once you find a problem, you can look up the relevant contents of dozens of scriptures in your mind to find a solution to the problem

After refining three heats of secondary pills in such a row, finally... All the secondary pills of the sixth furnace reached the level of the best pill when they were released. It's just... Of the ten pills in this furnace, only two pills with two patterns are produced, and the rest are all the best pills with one pattern.

That's it... After refining seven or eight heats again, he finally stabilized the quality of the secondary pill he refined at least two stripes, but he couldn't refine a five stripe best pill, up to four stripes.

Unconsciously, a few days passed again. Lu Shan didn't dare to delay any more, so he began to refine the third level pill.

If he goes on like this... He will feel that the difficulty of refining will increase greatly after each level is promoted. Fortunately, he has printed the contents of dozens of Dan classics in his mind. As long as he tries to refine one or two heats, he can probably find the problem.

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

When he learned level 5 pills, he had to refine nearly 20 heats of pills continuously, and finally a top-grade pill with Dan pattern appeared.

This makes Lushan secretly sigh that alchemy is indeed a very broad and profound knowledge... It's OK to say that level 1 and level 2 pills are above level 4... The difficulty has increased to a very amazing level. It's almost impossible to refine the best pills if you don't have strong divine soul power and almost instinctive control over the flame!
