After arranging Xu Changqing to the small courtyard room behind the bookstore, the bookstore owner left.

The sky outside gradually faded, and Xu Changqing could feel that this change of day and night did not occur naturally, but a kind of formation movement of the heaven and earth formation. Even the stars that appeared in the sky at this moment were the heart of the formation of this heaven and earth formation.

Xu Changqing just looked up and looked at the changes in the sky formation. He didn't even see clearly which ancient formation this formation was. He retreated back into the house and no longer looked at it, because he felt that the heaven and earth formation was alive and would react to any waiter.

When he looked up just now, a trace of inquiry had just arisen in his heart, and he immediately felt a force similar to divine thoughts projected from the formation in the sky and swept towards him. Fortunately, he realized it quickly and withdrew his gaze and thoughts in time, so that he was not discovered by that divine thoughts. Otherwise, the consequences would be imagined.

This situation made Xu Changqing feel that it was very strange here, both loose and rigorous. Overall, it looked like a cage with strange rules.

The cautious Xu Changqing waited until the unexpected force completely disappeared before he picked up the books on the Great Dao Method and read them again.

When choosing these books before, Xu Changqing spent some time. The great Taoist methods he selected were all the methods he practiced in the incomplete memory of Zhenyuanzi. Although there was no detailed content about these methods in the incomplete memory, it had various effects after the practitioners used them. Through these, Xu Changqing was able to unleash many secrets about the methods.

It took Xu Changqing, the first book of the Great Dao Method, to fully understand the mystery of the Great Dao contained in it for more than five hours, and also mastered the meaning of the words used in the practice of secret words here. This made it much easier for him to read other books on the Great Dao Method later, and the time it took was rapidly reduced, so that it only took one hour to read one.

But the more you know about the great methods that everyone practices here, the greater the doubts in Xu Changqing's mind. This is not because he found something wrong, but because he did not find anything wrong, but he always felt something unspeakable.

"What's wrong?" Xu Changqing closed a book of the practice method he had just read, closed his eyes and pondered for a moment, and did not continue to read the new Dao Method. Instead, he turned back and read the first Dao Method again. The carefulness of reading was the same as when he read it for the first time.

This repetition did not make Xu Changqing discover any problems, but during the repetition, the indescribable abnormal feeling deep in his heart aggravated a little.

Xu Changqing did not continue reading. After two careful studys, the contents of the book were completely imprinted in his mind. Even if he could not memorize it backwards, he could still remember it freshly.

He put the book aside and closed his eyes and recalled, but what he recalled was not the content of this great Tao method, but the powerful power of practicing this great Tao method in the prehistoric period.

This method is called Burning Heaven, and it was also very famous in the ancient times. Almost all acquired strong people on the prehistoric land who use the fire spirit as the main body to practice this method. It is said that after practicing this method to the Mahayana, a Burning Heaven Dao Flame that can be condensed even the scorching sun will be burned to ashes.

In Zhen Yuanzi's incomplete memory, it seems that only one person has practiced this method to the Mahayana realm. This person is the Zhurong lineage of the prehistoric clan. He has the innate fire spirit essence. After practicing this method, he is even more accompanied by his ministers. He finally achieved extraordinary results. After entering the Heavenly Court, he was appointed as the Fire-Starting Heavenly Lord, one of the five righteous gods of the Fire Division of the South Pole.

Xu Changqing carefully recalled the life of this powerful man from his incomplete memories. As the content of the memories increased, the strange feeling that had been produced by the great method in his heart gradually increased, and eventually a qualitative change occurred, allowing him to grasp the flash of inspiration in an instant.

Taking advantage of this inspiration that did not disappear, Xu Changqing picked up the book of the Great Dao Method and started reading it. This time he read it very quickly and it took only a few minutes to finish it. When he put down the books in his hand, the expression on his face became much more serious, and his eyes also looked through the open windows toward the stars in the sky that were imitated by formations, murmured: "Why? Why do you do this?"

Through the inspiration just now, Xu Changqing had discovered the reason for his abnormal feeling. This reason was not because there was any mistake in the Great Dao Method recorded in the books. In fact, the Great Dao Method in the books is very complete and there are no mistakes. As long as you practice in sequence according to the methods recorded in the books, you will eventually be able to achieve the right result.

However, all this is based on an unchangeable foundation, which is the prehistoric land.

The great master who created this method back then may not have thought about other problems. He just created this method according to the most suitable cultivation method of his body. This method is like all other methods, and the great Dao method created in the special environment of the prehistoric land. Once he leaves the prehistoric land, those great Dao methods will have some unpredictable problems.

In this regard, Zhen Yuanzi, who has been walking in various alien realms in the void for many years, has a deep understanding of this experience that remains in Zhen Yuanzi's memory, which makes Xu Changqing feel strange after seeing those great Taoist methods.

If you use the great Taoist methods created by the powerful giants on the prehistoric land according to their own situation to practice them, it is definitely impossible to cultivate any useful things, and even harmful things. Even if the people living in this world are some prehistoric aliens with more or less special bloodlines. More importantly, practicing this method requires a large amount of pure spiritual energy from heaven and earth, and this spiritual energy is also lacking in this world, so the prehistoric great Taoist methods like Burning Heaven are not suitable for people in this world to practice.

If a practitioner does not have any effect in practicing this kind of method, it would be fine. But the problem is that after losing the foundation of the prehistoric land, those who practice this kind of great way can still cultivate some magical powers and magic powers. Then it is obvious that the great way method is different from the prehistoric period. In other words, some people have modified the firing of that year to the extent that people who are now can also cultivate the effect.

When Xu Changqing just repeated the third time, he paid special attention to some of the practice details of the Dharma in the book. He found that those who modified these Great Dao Methods obviously had a deep understanding of this method, and their control over the power of blood has reached a very small level. After some modifications, the current Great Dao Methods such as Fentian no longer rely on absorbing external spiritual energy to practice, but provide the needs for cultivation by constantly stimulating the original energy of the prehistoric origin contained in their own bloodlines.

This has both advantages and disadvantages. The advantage is that with the special bloodline of the people in this world, they can quickly cultivate and achieve great strength and will produce different innate magical powers due to different bloodlines. However, the disadvantage is that they consume a large amount of their bloodline energy, which will cause their cultivation to stagnate after reaching a certain level. The more exquisitely they practice the Great Dao Method, the shorter their life span.

In fact, this kind of disadvantage is not impossible to avoid. You only need to practice some internal nourishment and bodybuilding methods while practicing the Natal Dao method, strengthen the power of bloodlines, and try not to use any external spells to weaken or even eliminate this disadvantage that damages bloodlines and longevity.

But the problem now is that Xu Changqing did not see any solution to the disadvantages in these books that record the Great Dao Method. Instead, there are several powerful spells attached to the books. All of these spells are the kind of external release type, which is simply a hidden danger in accelerating the practitioner.

Xu Changqing absolutely does not think that the Heavenly Palace in this world, which can improve all the great Dao methods, cannot see the disadvantages and solutions of these great Dao methods, but the result is the current situation. It is obvious that the only answer is that the Heavenly Palace does it on purpose. They just want the people at the bottom of this world to do this, and Xu Changqing is also confused about this.

Driven by puzzled emotions, Xu Changqing tried to cast a round light spell, and the casting situation was somewhat unexpected. He was sure that he had successfully cast the spell, but the moment his magic power surged out of his body, he was immediately affected by the mysterious force that caused him to fall to the ground, and the effect of the spell was finally weakened to the extreme. Originally, after he performed the round light spell, he could form a half-body-sized mysterious light mirror. The mirror might at least be reflected in the radius of twenty miles. However, the mysterious light mirror is half a palm-sized, and the mapped image cannot even cover the place where his body is now.

"So that's it." The abnormal situation in front of me was like an extremely clear reminder, which made Xu Changqing think of the reason quickly.

It is obvious that the Heavenly Palace in this world treats the people at the bottom of this world as sacrifices. Every time these people practice and cast spells, they will be sucked away part of their energy and spirit by the heaven and earth formation that covers the heaven and earth to supply the normal operation of the entire heaven and earth, and the giant tortoise carrying the heaven and earth, like a mummy corpse, and move normally. Even if these people die, the last trace of their remaining power and souls may be swallowed by the heaven and earth, becoming part of maintaining the movement of the heaven and earth.

Only by becoming a desolate man can one escape the erosion of this world. Xu Changqing estimated that those selected desolate men may be the kind of people who accidentally comprehend similar body refining and internal cultivation methods. If these people do not join the Heavenly Palace and join them, the result will be either destruction or imprisonment. This may be why a large number of desolate men can be selected every time, but only a few desolate men can return to this world.
