After comparing the similarities and differences between Xiuzhen and Immortal Cultivation, Ye Qiuli and Changchunzi made a comparison of the various stages of the two cultivation methods according to their own cultivation strength and cultivation experience, so as to have an intuitive understanding.

Through some careful comparison, they found that the period of qi introduction and entering the body of an immortal cultivator is almost equivalent to the four realms of foundation building, enlightenment, agility, and golden pill of a cultivator; the period of refining qi and transforming the spirit of an immortal cultivator is equivalent to the two realms of the cultivator's Yuan Infant and out-of-body existence; the period of refining the spirit of an immortal cultivator is equivalent to the three realms of distraction, merger, and tribulation of the cultivator; and the period of refining the void and merging the path of the immortal cultivator corresponds to the Mahayana period and the immortal realm of the cultivator.

From this comparison, we can also see the similarities and differences between the two cultivation methods of cultivating truth and cultivating immortals, these two are similar in the early stage of cultivation, both are the basic cultivation stage of polishing the body and purifying the physical body, and there is not much difference; when it comes to the middle and late stages of cultivation, it is completely different, and the difference is already quite significant, and slowly embark on two paths with their own characteristics, especially the cultivation in the later stage, each with its own ingenuity, and the difference is very huge.

In the late stage of cultivation, a cultivator has a merge period that allows the Yuan Infant to merge with the physical body to form a half-immortal body, which greatly enhances the strength of his physical body to increase the success rate of the tribulation. Immortal cultivators, on the other hand, will cultivate at the same time during the merger period and the tribulation period, and with the help of the power of the Heavenly Tribulation, they will directly cultivate a half-immortal body with true immortal attributes, and then meet the test of the second and third Heavenly Tribulations after greatly strengthening their own strength, so as to ensure the success rate of the Tribulation.

Compared to the cultivation method in which a cultivator can ascend to an immortal by only passing through one Heavenly Tribulation after being fully prepared, an Immortal Cultivator divides the Heavenly Tribulation into two or three times, although the overall power has increased a lot, but the intensity of each Heavenly Tribulation is relatively much lower, and it is easier to survive. This cultivation method has also greatly increased the success rate of the tribulation, and it is indeed difficult to say who is superior and who is inferior, and who wins and who loses.

Clearly distinguish the corresponding stages of the two cultivation methods, Ye Qiuli's cultivation in the late stage of Yuan Ying, coupled with his extremely strong body, his comprehensive strength is almost equivalent to the middle and late stage realm of immortal cultivators, according to Chang Wenzi's explanation, he is also one of the top figures in the ancient relic star immortal cultivation world. After all, although there are many masters of the Transformation Stage on their Ancient Relic Star now, the top masters of the Returning to the Void Stage have not appeared for a long time.

Moreover, according to past experience, as long as those top masters who have cultivated to the realm of returning to the void successfully break through, they will soon all leave the ancient relic star and enter the vast cosmic starry sky, embarking on the road of searching for the immortal realm. Therefore, for a long time, almost all the cultivation masters who have been active on the ancient relics are in the realm of refining qi and transforming gods, and it cannot be said that there are no masters of returning to the void and scattering immortals, but they are definitely rare, and it is rare to see one for thousands of years.

With such a comparison, it is natural to distinguish the similarities and differences between the two exercises of cultivating truth and cultivating immortals, which makes it clear at a glance.

It's just that in this way, Changchunzi once again had a puzzled question: "Daoyou once said that Daoyou spent 10 years flying over the starry sky to the ancient relic star, but looking at Daoyou's cultivation in refining and refining the realm of gods, it is not like being able to pass through the Gangfeng Thunder and Fire layer on his own?

"Gangfeng Thunder Fire Layer?" Hearing such a term from Changchunzi's mouth that he had never heard before, Ye Qiuli was also confused, when he flew away from the earth in a spaceship, he didn't seem to encounter this kind of thing. Moreover, there is no description of this in the cultivation materials left by Lu Yan and others, which has made it very clear that as long as the cultivation reaches the distraction stage, after using the method of teleportation, he can naturally fly out of the planet smoothly.

Puzzled in his heart, Ye Qiuli did not hesitate, and asked Changchunzi: "I don't know what the Gangfeng Thunder Fire Layer you are talking about?" According to what I know below, in addition to using the teleportation array to go to other planets, flying away from a planet alone does require a certain amount of cultivation as a foundation, and the cultivator's flight speed is fast enough to be able to break away from the planet's gravity. It's just that it doesn't seem to have anything to do with the Gangfeng Thunder Fire Layer!"

"Well, Daoist friends don't even know about the existence of the Gangfeng Thunder Fire Layer?" Regarding Ye Qiuli's question, Changchunzi was also a little inexplicable, and he didn't know why. The Gangfeng Thunder Fire Layer was almost a well-known knowledge in the Ancient Relic Star cultivation world, and there were very few people who didn't know it, he really couldn't imagine that a cultivator like Ye Qiuli, who could travel across planets and carry out interstellar travel, would know nothing about it.

It's just that after thinking that Ye Qiuli came from a cultivation civilization that was very different from their immortal cultivation civilization, he quickly let go of his feelings, and he was not surprised. It is very likely that cultivators of such a thing as the Gangfeng Thunder Fire Layer also know it, but they don't call it that, as long as they can say its specific manifestation, it is not difficult to match. This phenomenon of the same thing being called differently in different places is really all too common in the vast and boundless cultivation world.

After roughly guessing the difference, Chang Chunzi sorted out his language a little before continuing to answer: "This may be the confusion caused by the difference between you and me about the name of the Gangfeng Thunder Fire Layer, as long as the poor Dao describes it in detail, Daoist friends will definitely know what this is all about soon."

Daoyou has also said before that high monks need to have enough cultivation to travel freely between planets to be able to successfully break away from the gravitational pull of the planet itself and reach the cosmic void smoothly. But in fact, it is not enough to fly fast enough to successfully fly off the planet, and there are many other things to consider.

Fellow Daoists should know that the gravitational pull of different planets is actually different, and naturally, the speed required to break away from them is also different. On some planets with relatively small gravitational force, it stands to reason that they should be able to fly out at a lower speed, but this is not the case, when the cultivator's speed is enough, but the cultivation is not enough, he still can't fly out of the planet smoothly. And in this, it will involve the problem of the Gangfeng Thunder Fire Layer.

Starting from the ground and counting upwards, there will be an ordinary thunder layer at a distance of 3,000 zhang, in which there are often lightning flashes, ethereal and untraceable, very dangerous.

Above the thunder layer, 30,000 zhang is the Gangfeng layer, in which the Gangfeng is hugely powerful, blowing like a knife scraping an axe, very powerful, the body of the average monk can not withstand a few blows at all. Moreover, in addition to the powerful Gangfeng, the Gangfeng layer is often mixed with skyfire. The temperature of that day's fire was extremely high, and the three-flavor true fire emitted by ordinary cultivators could not be compared to it at all, and there were extremely many of them, almost endless, no matter how powerful a Qi Cultivation Divine Stage master was, he would not be able to stay in it for a moment or three, and if he was not careful, he would turn into ashes.

Above the Gangfeng layer, 90,000 zhang away is the Heavenly Thunder Layer, which is filled with countless super heavenly thunders. It was not those ordinary thunderbolts at low altitudes, but the real thunderstorms, that is, the Nine Heavens Divine Thunder that would only appear in the Heavenly Tribulation, which was extremely powerful, and each of them could be comparable to the full force of the masters of the Void Period! Moreover, these thunderstorms were quite spiritual, once they found that an unfamiliar target had broken in, they would immediately attack them in groups, and they would never stop without defeating and killing the invaders.

Gangfeng, Heavenly Fire, and Nine Heavens Divine Thunder, each of them is a heaven and earth divine power that cannot be underestimated, and if you don't pay attention to it, you will immediately end up with your soul scattered and ashes. In such an extremely dangerous natural environment, if a cultivator's cultivation was not strong enough, he would not be able to resist the continuous attacks of Gangfeng, thunder and fire, and he would have been split into flying ashes a long time ago. Therefore, after countless ancestors risked their lives to continue to investigate, they finally discovered that if they wanted to safely leap over the Gangfeng Thunder Fire Layer, they must at least have to refine the gods and return to the void period of cultivation, and only then could they withstand those continuous attacks. ”

"And this is also the most puzzling place of the poor Dao, looking at the cultivation of the Taoist at this time, it is obvious that he has not yet reached the realm of returning to the void, if there is no master to support, it is completely impossible to safely pass through the Gangfeng Thunder and Fire, but just now the Taoist friend has clearly explained that the Taoist friend is alone in the endless starry sky, from the earth to the ancient relic. This really puzzled Poor Dao!" After explaining the composition of the Gangfeng Thunder Fire Layer, Changchunzi added again with doubts.

Obviously, he was very curious and confused about how Ye Qiuli came to the Ancient Relic Star from the infinitely distant earth, and he still couldn't understand it with the knowledge he knew.

"I see. After hearing Chang Chunzi's explanation of the Gangfeng Thunder Fire Layer, Ye Qiuli finally knew what it was. According to the understanding of the earthlings, the so-called Gangfeng Thunder Fire Layer is the name given by immortal cultivators to the space environment outside the planet's atmosphere.

According to Changchunzi's explanation, and then comparing the scientific and technological knowledge he had learned, Ye Qiuli found that the ordinary thunder layer divided by the immortal cultivators was probably equivalent to the troposphere, and it was indeed the place where thunder and lightning were generated. The Gangfeng Tianhuo layer is roughly in the ionosphere, and the Tianlei layer belongs to outer space. It's just that, except for the ordinary thunder layer, which can match the number, the other two layers are not very similar, and there is a sense of plausibility.

Ye Qiuli was indeed puzzled by this situation, and after noticing that Changchunzi knew more about this aspect, he immediately continued to ask: "The ordinary thunder layer that Daoist friends said, I know that it is indeed easy to have lightning and thunder in the sky, but the Gangfeng layer and the heavenly thunder layer have not encountered it when they flew out of the planet. Although the tens of thousands of feet in the sky are also full of dangers, and uncontrollable accidents may occur if you are not careful, they are always quite stable, and there is no infinite wind and fire. And when we look up at the sky from the ground, it's also a blue sky, and we can't see the scene of thunder and fire!"
