Shen Lang is right, he is indeed not the only one who has paid attention to this problem.

For thousands of years, everyone has heard those myths and legends that have been passed down for a long time as a child, and although no one can come up with a real answer, there is no doubt that everyone has the same question in their minds.

Why did those legendary powers that could move mountains and reclaim the sea disappear collectively after the Xia Dynasty, as if they had never appeared?

At the time of the Xia Dynasty, what major things happened?

However, at this time, everyone did not show excessive doubt, because looking at the candle dragon with a subtle expression in front of them, everyone knew in their hearts that maybe this question would get a correct answer today.

"If you think only from a historical point of view, you have actually thought of the answer, it is indeed because the Xia Dynasty changed from the Zen system to the hereditary system, and later dynasties all followed this system of the Xia Dynasty, so the Xia Dynasty is the beginning of the Shenzhou Dynasty recognized by later generations."

In our expectant gaze, the candle dragon spoke again, spitting out a secret from his mouth that no one now knew.

"But if you look at it from the other side, this matter is far more than that, in addition to the historical perspective that you know, the changes that have occurred within Shenzhou are the deep reasons for this change."

"I have already said just now that before the Xia Dynasty, the great powers of Shenzhou abounded, but after the Xia Dynasty, except for the Battle of the Gods, there seemed to be no legends of these great powers, and the real reason why there were such great changes during the Xia Dynasty was because of the withering of the spiritual energy of Shenzhou."

Although Candle Dragon's explanation sounds very clear and easy to understand, in fact, we still can't understand what he is saying today.

Will the withering of Shenzhou's aura suddenly cause such a big change?

"As the so-called conservation of the Heavenly Dao, no one can go against it, the Heavenly Dao is above everything, except for the Pangu God who holds the axe to open the sky, even if Nuwa Niangniang returns to Shenzhou, she can only perceive the trajectory of the Heavenly Dao in advance at certain moments, but she can definitely not completely disobey the operation of the Heavenly Dao."

Naturally, the candle dragon knew that we could not understand what he had just said, so he continued to explain to us without waiting for us to ask.

"If there is no Rahu, the operation of the Heavenly Dao would have been perfect, although the cultivators need to rely on the spiritual energy to practice, but after the cultivators have achieved cultivation, they will feed the spiritual energy back to the heaven and the earth, and under this cycle, there will be no day when the spiritual energy will be exhausted in this heaven and earth."

"But the Heavenly Dao is not omniscient and omnipotent, for the existence of the Demon Ancestor Rahu, the Heavenly Dao is completely unable to grasp, and it is precisely because of the appearance of Rahu that the seemingly perfect cycle of the Heavenly Dao was finally broken."

For the cycle in the mouth of the candle dragon, we inevitably heard the clouds, and we didn't know very much, seeing this, the candle dragon sighed slightly, and then explained to us in more detail.

"You may not know that the aura of this heaven and earth is a fixed number, how much you need to absorb when you practice, how much will the aura in this heaven and earth be reduced, and only when you cultivate to feed back to heaven and earth, this feedback aura can make up for the previous losses."

"Therefore, according to the normal situation, although the Divine Aura, although it will never be complete, it is completely enough for the cultivator to circulate, but after Rahu appears, all this can only be regarded as a good wish."

With Candle Dragon's explanation, we seemed to slowly understand the meaning of his words, and the expressions on each other's faces couldn't help but become solemn.

The candle dragon ignored our reaction and continued in an unchanged tone.

"Heavenly Dao naturally knows that Rahu has absorbed the obsession of the three thousand Chaos Demon Gods, and the self-proclaimed Demon Ancestor is hidden in the land of Shenzhou, but Heavenly Dao has neglected an extremely important point, that is, Rahu's existence itself will spontaneously absorb the aura between heaven and earth, and will never feed back half a point to this heaven and earth."

"It is precisely because of this characteristic of Rahu that as long as Rahu exists in the world for a day, the aura of this heaven and earth will be absorbed by it, and it will become scarcer and rarer, until the time of the Xia Dynasty, the aura of the land of Shenzhou has finally reached the level of withering."

As Candle Dragon narrated, we slowly sorted out what he wanted to express to us, but Candle Dragon seemed to be afraid that we would still not be able to understand, so the words did not stop, and the tone did not change.

"In your cognition, those powers that can move mountains and reclaim seas and pick stars with bare hands should have no desires, but in fact, although their cultivation has already reached an astonishing level, they are not without need, if they want to maintain their cultivation, they also need the support of spiritual energy."

"Because of this, after discovering that the aura of the land of Shenzhou was depleted, these great powers couldn't help but fall into a panic, in order to avoid the end of their own cultivation being damaged or even dying, they came up with all kinds of methods, but the result was obvious, all methods were completely unable to resist the rules of the Heavenly Dao, and in the end they could only end up in a useless end."

"And at this moment, Emperor Yu, who had been missing for a long time, reappeared, and Emperor Yu revealed his identity, and called on the world's cultivators to gather together with his former prestige to discuss how to deal with the depletion of spiritual energy."

Speaking of which, the candle dragon finally stopped talking, leaving time for us to think for ourselves, and after hearing this, we already have a general understanding of what the candle dragon said before.

There is no doubt that if a cultivator wants to practice, in addition to talent and exercises, the most important thing is the aura between heaven and earth.

If we look at it from this point of view, then Reiki is undoubtedly the most important foundation for all cultivators in the world.

Originally, because of the conservation of the Heavenly Dao, the existence of spiritual energy is a fixed number, and it will never be increased or decreased at will, so the spiritual energy of Shenzhou can support so many great powers to practice at the same time, because after they practice to a certain stage, they will spontaneously feed the spiritual energy back to heaven and earth to make up for the previous losses.

But Rahu's presence made all this unattainable.

Rahu, like all cultivators in heaven and earth, will spontaneously absorb the aura in Shenzhou, but Rahu is different from other cultivators in Shenzhou, no matter how much aura he absorbs, he will never give back half a cent to Shenzhou, and in the long run, Shenzhou's aura will inevitably become scarce day by day, and even on the verge of exhaustion.

There is no doubt that as the foundation of a cultivator's cultivation, once the spiritual energy of the Divine Prefecture is exhausted, then the cultivators in the Divine Prefecture will undoubtedly face a catastrophe.
