Zhang Hao picked up a book on the first floor and looked at it, it was all about the cultivation of the Qi cultivation period, and most of them were about building the foundation.

There are various versions of experience solutions here, strengthening the meridians, lack of aura, cyclone integration, immortal roots can't penetrate into the void, immortal roots absorb chaotic breath too slowly, immortal roots can't metamorphose, and the choice of various foundation building exercises......

It's just that all the immortal cultivators above are cultivating Qi and building a foundation at the tenth layer!

There is no mention of the eleventh layer of Qi training, the twelfth layer of Qi training, and the thirteenth layer of Qi training at all!

After reading more than half of the book, Zhang Hao climbed to the second floor.

There are more books on the second floor, almost twice as many as on the first floor!

Zhang Hao picked up a book, the title of the book is: On the importance of foundation building exercises!

Zhang Hao turned the first page and saw that it was openly written: Choose a low-level foundation building technique to complete the foundation building period cultivation faster, so that you can have the hope of knotting Dan!

On the following pages, those immortal cultivators were all admonishing them to choose low-level foundation building exercises, and they also listed many difficulties in cultivating high-level foundation building exercises, among which the most difficult to cultivate was the "Haotian Dao Sutra"!

Zhang Hao smiled, thinking that the title of this book should be changed: On the necessity of low-level foundation building exercises!

But then Zhang Hao couldn't laugh.

There is a page that clearly reads: The low-level foundation building exercise can be refined and generated a hundred strands of spiritual power every day!

Zhang Hao remembered that at first, it would take him ten days to refine and generate a trace of Haotian spiritual power by cultivating the foundation building technique of the "Haotian Dao Sutra"!

In other words: the low-level foundation building technique is a thousand times the cultivation speed of the Haotian Dao Sutra!

Zhang Hao was stunned for a moment, and couldn't help but think that if he had chosen a low-level foundation building technique, would he have broken through to the Jindan stage now?

It's no wonder that Master Yun kept introducing the foundation building exercises at that time!

After reading page by page, Zhang Hao summed up one sentence: Either pursue cultivation speed or obtain powerful spiritual power, and the two are inversely proportional!

For the Five Rank Immortal Roots, the cultivation speed is the first thing, because they are not qualified to obtain powerful spiritual power, otherwise they will die of old age in the foundation building period!

Zhang Hao sighed lowly, if there was no pseudo-Dharma Body Exercise of "The Body of Ten Thousand Laws", he would also die of old age in the middle of foundation building!

It's just that immortal cultivators are all lucky and choose advanced foundation building techniques, so that they can gain strong strength.

So, every page of this book is an exhortation!

Zhang Hao glanced at the books on this shelf, all of which were about the selection of foundation building exercises.

Zhang Hao walked to the bookshelf next to him and picked up a book, the title of the book was: How to speed up the immortal root to absorb the aura of chaos?

Zhang Hao flipped through the pages and found that it was the most difficult thing for the immortal root to absorb the chaotic aura!

The low-level foundation building technique can refine and generate a hundred threads of spiritual power every day, which is only theoretical, the lack of chaotic breath can only refine and generate ten threads of spiritual power every day!

Therefore, every foundation building period monk can be said to have tried his best in order to allow the immortal root to absorb more chaotic aura!

And the most effective way to do this is to raise a group of foundation building stage cultivators and directly absorb the chaotic aura from their Qi Sea Dantian!

There is also a mention of the Chaos Bead in the book, and the Chaos Bead is praised as the first treasure in the foundation building period!

Glancing at this bookshelf, Zhang Hao walked to the side and picked up another book, the title of the book is: Lack of aura, helpless!

......

After looking at more than a dozen bookshelves in a row, Zhang Hao realized that there were so many problems in the cultivation of the early stage of foundation building alone!

And he has the Chaos Bead, the Dragon Ball, and the Body of Ten Thousand Laws, so he can ignore these issues.

Then, Zhang Hao picked up the book on the bookshelf next to him, and the title of the book was: Is the Void Pill Powerful or Not!

Finally, the issue of the middle stage of foundation building was mentioned, and Zhang Hao immediately opened the book.

On the first page, it is written: The foundation building method determines the strength of the Void Pill!

The same truth is stated on the following pages: the more advanced the foundation building technique, the more powerful the Void Pill formed!

But then the more advanced the foundation building method, the more difficult it is to cultivate, please choose carefully!

It's just that the upper limit of the spiritual power mentioned in this book is 512,000 threads, and the spiritual power of a Qi Sea Dantian is used to form a void pill.

Zhang Hao smiled, the upper limit of his Haotian spiritual power was fifteen times that of theirs! Moreover, he had cultivated the highest level of the Haotian Dao Sutra Foundation Building Technique!

Therefore, their own Void Pill is dozens of times more powerful than theirs, or even hundreds of times stronger!

Thinking about it like this, Zhang Hao suddenly felt that it was completely worth it for him to retreat and practice for so long!

It took a long time to read this bookshelf before Zhang Hao walked to the bookshelf next to him.

Pick up a book, and the title of the book is: How to improve the speed of condensation of the Void Pill?

Zhang Hao's spirits perked up, this was exactly the purpose of his coming to the Heavenly Demon Sect.

Turning the first page, there are only five words on it: Only return to the void pill!

Guixu Dan?

Zhang Hao then flipped down, and saw that it was written: A Guixu Pill can last for ten days to increase the condensation speed by 100 times!

100 times the speed! Zhang Hao was overjoyed in his heart, he could complete the mid-stage cultivation of foundation building with a hundred times the speed!

But the latter sentence made Zhang Hao frown: You can only take one pill a year, otherwise the residue of the pill will block the meridians!

In other words, it can only speed up by ten days a year!

The next page becomes how to solve the problem of blocked meridians......

Subsequently, Zhang Hao finished reading all the books on this shelf, all of which were solving the problem of meridian blockage!

And the way to improve the condensation speed of the Void Pill is really "only the Guiru Dan"!

With this question, Zhang Hao looked through all the books again.

It is mentioned in the book: The meridians are extremely fragile, and it is important not to use brutal means to remove the residue of the elixir!

......

The methods mentioned by the senior monks are very troublesome, which makes Zhang Hao have a headache when he sees it!

At this moment, three bells rang, and the other monks put down their books and hurried downstairs!

Zhang Hao also put down the book and followed downstairs.

When I walked out of the Gongfa Hall, I turned around and saw the door of the temple slowly closing!

Along the way he came, Zhang Hao walked towards the alchemy room.

Along the way, he was checked by seven or eight patrol disciples.

Returning to the alchemy room, Zhang Hao saw the fat man supervising the service from a distance, and waited for a while before greeting him.

Zhang Hao asked directly: "Where is the Guixu Dan for sale?"

Because it is mentioned in the book, Guixu Dan is a relatively common pill.

The fat man smiled: "Daoist friends can buy it directly from me!"

Zhang Hao asked, "What price?"

"Two hundred low-grade spirit stones, one!, or two for ten days of service!" the fat man replied.

"Then I'll buy one first!" Zhang Hao took out the spirit stone.

Seeing the spirit stone, the fat man immediately took out a Guixu Pill and handed it to Zhang Hao.

Zhang Hao took the Guixu Pill, and according to the identification method in the book, he first looked at the color, then asked about the smell, and finally sent a trace of Haotian spiritual power into it, and felt that Haotian's spiritual power was absorbed by this pill.

The fat man waited for Zhang Hao to be sure before he said: "Don't worry, Daoyou, what I am doing is a long-term business, and I will not ruin my reputation for this spirit stone!"

Zhang Hao nodded and put away the Guixu Dan.

Zhang Hao asked again: "I want to learn some small dao spells, do you have a way?"

The fat man smiled and did not answer.

Zhang Hao took out ten lower grade spirit stones and handed them over.

The fat man hurriedly took the spirit stone, "I am very familiar with the guarding disciples of the Second Pavilion of Dharma Transmission, and I can bring Daoist friends over." ”

"Second Pavilion of Fa Transmission?" Zhang Hao was puzzled.

"This Second Pavilion of Dharma Transmission was newly built after the merger of the three major sects, and it has collected all the small path spells of the three major sects, with a total of twelve thousand five hundred and ninety-seven sects!" the fat man explained.

"Then do I want to go in?" Zhang Hao looked at the fat man.

The fat man leaned over and whispered, "Just quietly stuff three hundred lower grade spirit stones to the guarding disciples!"

Zhang Hao nodded, knowing what to do.

Subsequently, the fat man took Zhang Hao to the Second Pavilion of Dharma Transmission.

This newly built Second Pavilion of Dharma Transmission is much larger than Zhang Hao imagined, it is an independent attic built at the foot of the mountain, divided into five floors, with four exits in the southeast, northwest and northwest, and each exit has a guard disciple!

"I'll take you in through the north gate!" the fat man said in a low voice: "The guarding disciple of the north gate was originally my fellow senior brother of the Danding Sect!"

Zhang Hao asked, "What about the guarding disciples of the other three sects?"

"The East Gate and the West Gate are both from the Heavenly Demon Sect! The South Gate is from the Immortal Sword Sect!" the fat man replied.

"Then I'm going to pay the spirit stones from the north gate later?" Zhang Hao asked again.

The fat man waved his hand, "This is up to you, the price of the four doors is the same anyway! If you can pay the spirit stone at the north gate, of course it is the best." ”
