Lu Feilong returned to the library building, Xie Honghui had not come back yet, Lu Feilong went directly to the fifth floor, and after sitting down, he looked through the books given by the dean. It turns out that these books are not real books, they are all some opinions and conjectures about the law book written by predecessors, and they can be regarded as notes left by predecessors, but these are all written by famous masters at that time, which is very helpful to Lu Feilong now.

While reading the notes of these predecessors, Lu Feilong simply verified with his own cultivation and wrote down all the key positions.

After reading three notebooks in a row, Lu Feilong stopped and began to concentrate on verifying his cultivation.

Lu Feilong left all the things that were useful to him, and gave up the other things that were not right, and it took an hour and a half for Lu Feilong to verify the three notebooks, memorize all the useful things, and then slowly study and comprehend them later.

Lu Feilong picked up the fourth book, and after turning the first page, he let out an exclamation: "I'm damned, there is still such a treasure... ”

It turned out that this fourth book was the experience and experience left by a senior who had cultivated the second half of the Fa Book, which was what Lu Feilong needed the most, which directly made Lu Feilong burst into foul language with excitement.

Lu Feilong looked at it very slowly and carefully this time, and pondered every sentence carefully; just three notes just now were just ways and means of verifying each other's cultivation, and this note could completely verify whether Lu Feilong's cultivation was right or wrong, which was definitely the best treasure for Lu Feilong.

After Lu Feilong read the two pages, he was very glad that he didn't rush forward, and he didn't cultivate until he had figured out the lower half of the law book, which made his cultivation direction not wrong, which was the most important thing; at the same time, Lu Feilong also knew that the upper half of the law book that was not valued by others was also very important, and many places in the upper half were explanations of the lower half.

Lu Feilong looked down very excitedly, but the more he looked at it, the more wrong it became, and slowly the cultivation process recorded in this notebook had a certain deviation from Lu Feilong's cognition;

"This can't be???" Lu Feilong kept saying.

After reading the entire notebook, Lu Feilong's head was buzzing, and he was confused.

What is recorded at the back of this notebook is the explanation of the law book by the senior who has cultivated the law book, but this explanation made Lu Feilong's boiling blood fall into the ice cellar.

It turned out that in this notebook, the senior said that the second half of the exercises in the law book that Lu Feilong is now practicing are just foundation building methods; but although they are only foundation building methods, after the cultivation is completed, they can reach the ranks of the top masters in this world, and they can also become super masters who are praised by others; if you want to continue to practice the following exercises, you need a very harsh condition, that is, you need to use eighteen kinds of yellow-level cultivation materials to provide energy, and break through the gap between the foundation building exercises and the introductory exercises of this set of exercises, so that you can practice the introductory exercises。

In the past or in ancient times, the high-level treasures between heaven and earth were divided into four levels, namely the four top levels of heaven, earth, Xuan, and Huang, the highest level of heaven, the lowest level of yellow, and the treasure level worse than the yellow level. The spirit weapon level was all garbage at that time, but then I don't know what changed, this world was like being cut off, those masters were gone, and this world became what it is now, and at the same time, those high-level cultivation materials before were also gone, and those high-level cultivation materials also became legendary things.

That senior cultivated to the stage of entry, but because there were not so many yellow-level materials, he had not made a breakthrough, and he spent his whole life and energy to find five yellow-level materials, and in the end, he still did not practice the introductory exercises.

However, the senior also guessed that the original world was layered, and their current world was the lowest world, and there were no high-level cultivation materials; if it was a high-level world, then there should be high-level cultivation materials; maybe only by flying to the world of the upper layer could they get so many yellow-level materials, but there would be countless masters in the world of the upper layer, and they would only exist at the very end, and they would have to climb up from the lowest level, so it was better to stay in this world for a lifetime.

At the end of the note, there is the warning of the senior: that senior has accumulated too much aura in his body, and the aura is still pouring into his body, he has already felt the day when he was filled with aura, so he warned future generations that before practicing this set of exercises, you must be mentally prepared, if you don't have the confidence to break through to the upper realm or are afraid that you will be filled with aura, remember not to take chances to practice this set of exercises!!, remember!

"The pit, the big pit, the huge pit, the god pit... Lu Feilong suddenly raised his head to the sky and roared.

At the beginning, that senior also found five yellow-level materials, but now in this world, let alone yellow-level materials, there are no treasure-level materials, that is, the spirit weapon-level materials are all priceless, which makes Lu Feilong go somewhere to find yellow-level materials? Break through to the upper world, that is even more difficult, although the Lu family is a small family, but they still know some news about the whole world, as far as Lu Feilong knows, no one has flown to the previous world for thousands of years.

After a long time, Lu Feilong slowly put away a few notes, and then suddenly fell to the ground again, and then said, "Ahhhhh He shouted as he waved his arms and stomped his feet, venting his emotions.

After venting for a while, Lu Feilong sat on the ground panting, slowly picked up a few notes, wiped all the dust on the books, and then put them on the bookshelf next to him.

"Do I have any other choice now? Even if I don't cultivate myself, the aura around me is constantly drilling into my body, and I will end up being filled with aura in the end. Lu Feilong said to himself.

After a while, Lu Feilong then said to himself: "If I continue to cultivate, I may be able to reach the strength of Ascending to the Upper World, and I may be able to find enough Yellow-level materials when I reach the Upper World;

"There is another situation that I continue to cultivate, but I can't fly to the next level of the world, it can only make me die faster from the aura explosion; ”
