After carefully thinking about the mystery of the Cave Heaven Realm, Zhou Tong immediately began to figure out the mystery.

With the cultivation experience of the Emperor of the Desolate Heaven, as well as the supreme secret method, Zhou Tong has a new understanding of the Cave Heaven Realm in his heart every time he participates in the enlightenment.

More than ten days passed in a flash, and he felt the mountain of Ninety-Nine Dragon Mountain here every day, looking at the trajectory of the sun, moon and stars, listening to the pulse of this mountain, smelling the fragrance of medicinal herbs, and the whole person became more and more ethereal.

He seemed to be stupid, and he seemed to have left everything behind, and devoted himself to his next transformation, constantly comprehending the Fa, studying the mysteries of runes, and comprehending the mysteries of the Thunder Emperor Law and the natural fluctuations of heaven and earth.

On the Ninety-Nine Dragon Mountain, it is extremely quiet, no one disturbs it, and sometimes the breeze blows, bringing bursts of medicinal fragrance. Zhou Tong always sat here, immersed in the world of cultivation, and even his eyes opened and closed, and there were runes of disillusionment.

And on this day, suddenly Zhou Tong seemed to have comprehended something, and he grasped the true essence of the Cave Heaven Realm. In an instant, the whole person was sublimated, and the whole body was crystal clear, and it was contained by runes.

At this moment, his whole body seemed to be made of immortal gold, exuding a brilliant treasure light, and one rune after another evolved into a thunder god, absorbing the creation of heaven and earth, refining the divine essence, and preparing him for the next opening of the cave sky.

The Cave Heaven Realm is a cultivation realm in the chaotic ancient law, and it is also a means of cultivation. This realm pays attention to absorbing the creation of heaven and earth, realizing the true meaning of runes, understanding the order and rules of this world, and then reopening a small world!

This is the so-called Cave Heaven Realm, which opens up a pure land and a world in the human body or outside the body!

"Boom!"

Just when everything was ready, suddenly a grand sound came out, shaking the entire Ninety-Nine Dragon Mountain, and even the immortal mist that permeated the Dragon Mountain seemed to be attracted and descended a little.

I saw a brilliant rune suddenly appear, dense, dazzling, each rune was like a brilliant immortal gold casting, imprinted in this void, completely submerging Zhou Tong.

"Buzz!"

At the same time, a surging qi and blood rushed into the sky, like the Yangtze River rolling in, and finally a volcano-like cave appeared above Zhou Tong's head.

This is the cave!

It is so real, as if it is really carved out of rocks, gray-brown throughout, quaint and atmospheric, suspended about a meter above Zhou Tong's head.

In this cavern like a volcanic crater, there is a surging breath of life. Red as blood, brilliant as gold, dazzling, rolling like magma.

The so-called Cave Heaven Realm is actually a realm of heaven and earth creation. The cave heaven communicates with the power of the natural order of heaven and earth, and then absorbs these things from the outside world, and then smelts and communicates with itself, and finally forms the magma-like rolling life essence inside the cave sky.

Cultivating to this realm is equivalent to communicating with the outside world and drawing divine power from heaven and earth, and from then on, it will be endless, and the human body can always maintain its vitality.

It can be said that as long as you cultivate to this realm, as long as you don't fight too tragically, it will be difficult to exhaust your own strength at all, and you can always stay at the peak of your peak.

"Boom!"

At this moment, in the cave above Zhou Tong's head, there was a constant surge of bright red essence like blood, and then naturally flowed downward, falling into Zhou Tong's body.

"Whew!!"

It was like a gust of fresh wind blowing, and there seemed to be a whirlwind in the Ninety-Nine Dragon Mountain. The whirlwind blew the essence emanating from the Dragon Mountain, and began to pour into the cave sky of Zhou Tong.

This is the most direct and rapid plundering from the outside world, which shows the domineering of the Cave Heaven Realm.

The Ninety-Nine Dragon Mountain, which was already extremely vigorous, was stimulated by this, and suddenly a massive amount of mist began to linger around Zhou Tong.

"I see, is this the Cave Heaven Realm?" Zhou Tong felt more and more mysterious in his heart.

Just opened a cave in the sky, and he felt that the whole body was comfortable, as if he was about to feather and soar; The essence from the Ninety-Nine Dragon Mountain is too abundant.

The endless essence was moisturized, and the flow of essence in the cave was even more rapid, and Zhou Tong felt warm all over his body, his whole body was crystal brilliant, and his face was even redder!

"Boom!"

At this moment, Zhou Tong's body trembled violently, and he roared again, and the glow was full of light, and the rumbling sound was deafening. To the left of its body, a gray-brown crater appeared, with silver "lava" billowing and flowing.

"The Second Cave Heaven!" Zhou Tian couldn't help but show a smile on his face.

With his own accumulation in the Blood Moving Realm, once he opens up the Cave Heaven, there will definitely be more than one bite!

This is the moment.

"Boom!"

Soon, there was another light tremble, and then the runes filled the sky, surging like an ocean, forming an infinite order realm here, spraying thin Ruixia.

The third cave was formed.

"Boom!" "Boom!"

Then, there were two more sounds, and then there were gusts of wind and thunder, only to see the purple gas around Zhou Tong steaming, the clouds and mist were ethereal, and the glow was bursting, and the color was surging.

The Fourth Cave Heaven and the Fifth Cave Heaven were also formed at this moment!

At this point, Zhou Tong's breakthrough was the real end, only to see five gray-brown craters forming around him, continuously drawing power from the void, red, silver, purple, gold, and cyan "magma" surged, submerging into his body.

"As soon as you break through, it's five cave heavens, which is more than the Emperor of the Desolate Heaven back then!" Zhou Tong said silently in his heart.

Of course, he didn't have the slightest pride in his heart.

Because his accumulation of the background in the Blood Moving Realm was completely completed by relying on the secret method of Thunder Quenching the Body, and the Emperor of the Desolate Heaven did not have such a secret method back then.

Moreover, the place where he broke through was Ninety-Nine Dragon Mountain, and the environment in which Emperor Huangtian broke through was far inferior to himself.

The most important thing is that when you break through, you have the insights of your predecessors to refer to; But the Emperor of the Desolate Heaven relied entirely on his own perception to cultivate.

"However, since we have entered the Cave Heaven Realm, we must complete this realm!"

Immediately, he sat down cross-legged, quietly realized the feeling of the cave heaven realm, immersed in it, the "magma" in the cave sky gushed out, submerging him, and for a while, Zhou Tong's side was full of light and mist, which looked extremely mysterious.

It took him a day to realize that he stopped, stood up, and the five craters were restrained and gradually disappeared.

"Huh!?"

However, at the moment when the cave was closed, Zhou Tong suddenly felt that there seemed to be a trace of waves in his lower abdomen.

"Wheels? Could it be that my wheel is about to open? Zhou Tong was ecstatic in his heart, but then he understood, "Yes, the original Wheel Sea Secret Realm was opened up and evolved by the Emperor of the Wild Heaven with the only Cave Heaven, and the Wheel Sea itself is an extremely similar thing to the Cave Heaven!" ”

As soon as he thought of this, he immediately sat down cross-legged and began to activate the wheel sea again in the manner of the Feather Sutra.

After all, the chaotic ancient law is just an expedient measure to lay a foundation, and this law has now been eliminated by the times, and it is really necessary to take the road of covering the sky.
