"Failed again...... Is it necessary to have a miracle medicine or open up the Ten Caves of Heaven to activate the Wheel Sea? Zhou Tong sighed again.

However, this time when he hit the wheel of the sea, he could already feel that his wheel of life was as hard as divine iron, even if he used the essence of the five cave heavens to attack, he couldn't break it, and he could only shake it slightly.

You must know that when he tried to practice before, there was a complete silence in his chakra, and he couldn't feel anything, even if it was impacted, he only felt that it hit the iron plate; But now I can feel more clearly what I have hit on.

"Since that's the case, then continue to practice, if the five caves can't work, then open up the ten!" Zhou Tong also has a ruthless energy, since he has decided to embark on this cultivation path, he will never allow himself to give up halfway.

"First of all, it is still the thunder quenching body, and if you cultivate to the Cave Heaven Realm, this secret method can continue to be cultivated!" Zhou Tong continued along the safe road on the Ninety-Nine Dragon Mountain, and soon he found another elixir that was thirty or forty thousand years old.

Without thinking much about it, he continued to urge the Thunder Emperor Law as before, and suddenly a huge thunder dragon emerged and slammed into Zhou Tong's body, opening his skin for a while.

At the same time, he began to guide the elixir in his body, and used all the medicinal properties in it to repair his body and strengthen his physique.

He still practiced while advancing, and the countless elixirs along the way could be used to supply his cultivation. The deeper you go, the more amazing the elixir years along the way become, and the more convenient Zhou Tong's cultivation becomes.

Suddenly, Zhou Tong's expression in the advance froze, and he saw a person sitting on a piece of blue jade in a stone forest, with a solemn appearance and a fairy aura.

On his body, wisps of terrifying qi emanated, incomparably terrifying, each wisp weighed more than 10,000 jun, like a demon mountain oppressing.

"What a strong oppressive force...... The moment he saw this person, Zhou Tong felt that his body was trembling.

This power is really amazing.

"The Great Sage, definitely a Great Sage! Die here! Zhou Tong's heart was shocked, this was the first time he had seen such a powerful creature.

If he is still alive, this breath alone can crush him.

"It's a pity that I can't check the body of this great sage, otherwise I can get a great sage treasure!" Zhou Tong also felt a pity in his heart, if he could get this treasure, maybe for a long time in the future, he would not lack things to protect the Dao.

"But it's okay, with the oppressive power of this great sage's corpse, as well as the elixir just picked, you may be able to smelt the sixth cave heaven!" Zhou Tong immediately sat down cross-legged in front of this great sage, and while comprehending the Thunder Emperor Method, he swallowed a leaf of the elixir he had obtained before.

Suddenly, the huge medicinal properties of this spirit leaf turned into a cyan flame in Zhou Tong's body, burning fiercely, scorching his muscles and bones, and tempering his flesh and blood.

Eventually, Zhou Tian opened his eyes, and a brand new "volcano" appeared beside him.

At this point, he has opened up the sixth cave heaven, and his strength has improved again!

At this time, Zhou Tong's whole body was full of essence, and the sixth cave sky was constantly spewing thin essence, runes intertwined, lightning and thunder, as if he was opening the world.

For a whole day, Zhou Tong remained motionless, comprehending the mystery of the runes and realizing the new power.

"Actually, for me, who has the experience of cultivating the disciples of the Emperor of the Desolate Heavens, the cultivation of the Cave Heaven Realm is not too difficult, and all kinds of things that need to be perceived actually have a certain method of comprehension......" Zhou Tian recalled the cultivation method again in his heart, and said silently in his heart.

At the beginning of cultivation, the easiest thing is to follow the footsteps of predecessors, because in the early stage of cultivation, you don't need anything of your own at all. Only after attaining a certain level of cultivation can one realize one's own path.

Of course, if you blindly imitate your predecessors in the early stage, then you may not know how to go when you need to go your own way.

This is also the reason why many Great Emperors and Ancient Emperor bloodlines have not been able to finally preach.

They all took shortcuts at the beginning, so when they need to take their own steps to create a path, they have to have less "determination" and "experience" than those who work hard from the bottom.

Why is the Emperor of the Wasteland so powerful that he even opens up a system? It is because from the beginning of his cultivation that he has had his own thinking, and the path he has taken is all thought out by himself, without referring to the path of his predecessors.

"Although I am also blindly imitating, but for me, the ancient method is just an expedient measure, what I need is to use the cave heaven to open up the wheel sea, and then directly transfer to the method of covering the sky!" Zhou Tong already had some calculations in his heart, he didn't pause and continued to move forward.

Turning left and right, entering a hilly area, Zhou Tong quickly felt a burst of bloody aura. There was a burst of red in front of him, the blood was steaming, and outside the safe area, another great sage was burning. He was much worse than the previous Great Sage, and half of his body was withered.

Moving on, soon the corpse of the third Great Sage also appeared in front of him, and the corpse of this Great Sage was even more terrifying, his whole body was almost burned out, leaving only a bone and a little blood.

The further he went, the more terrifying the formation here became, and when Zhou Tong approached the Pregnant Immortal Valley surrounded by ten thousand dragon head peaks, Zhou Tong suddenly felt that his whole body was targeted by a killing intent, as if he was going to cut himself with a thousand knives. He involuntarily bulged the muscles all over his body.

This killing intent is not only aimed at the physical body, but also the primordial spirit.

"Hmm...... What a terrible killing intent!! Zhou Tong's breathing was a little short.

He was very sure that if he hadn't experienced the Thunder Quenching Body before, which was a painful cultivation test that almost cut him with a thousand swords, he would definitely be driven crazy by this killing intent, and then rush into the dangerous area on the side.

"In a short period of time, we can't move on!" Zhou Tong said silently in his heart, and then sat down cross-legged directly, while fighting against this killing intent, while quietly understanding the cultivation mystery of the Thunder Emperor Law and the Cave Heaven Secret Realm.

Time passed day by day, and half a year passed in the blink of an eye.

Finally, with the help of the huge essence on Dragon Mountain, the ubiquitous stimulation of killing intent, and the elixir that can be seen everywhere, Zhou Tong finally opened up the ninth cave heaven.

All kinds of symbols flickered, and a huge amount of runes erupted from the nine cave heavens, and the rune culture became a galaxy, constantly flying around Zhou Tong.

The scene here became more and more mysterious and amazing, and finally in Zhoutong's Nine Cave Heavens, there were nine kinds of divine birds and fierce beasts, such as the Thunder Emperor, the Fox Fox, the Thunder Sky Sparrow, the Golden-winged Dapeng, the Han Zhu, the Pixiu, the Five-colored Peacock, the Ancient Mangniu, and the Lightning Worm, all of which were in a state of runes and had no spirituality.

These nine kinds of divine birds and fierce beasts are all treasures that Zhou Tong inherited from the memory of the disciples of the Emperor of the Desolate Heaven. It's just that except for the Thunder Emperor's Treasure Technique, the Fox Treasure Technique, and the Thunder Sky Sparrow Treasure Technique, the other treasure techniques are only fragments.

This is an opportunity to open up the Nine Cave Heavens, and it is a rare opportunity to comprehend the runes of the treasure arts that can manifest all the treasure runes in my heart.

At this moment, Zhou Tong felt as if he had been incarnated as a fox, majestic and sacred, soaring from the earth, invincible in the world.

Subsequently, Zhou Tong felt as if he had turned into a golden-winged roc, soaring upwards for nine days.

After that, he felt as if he had turned into the Thunder Emperor, controlling the thunder, ruling the heavenly punishment, and dominating all beings.

In the end, all the runes poured in together, causing Zhou Tong to see a new world that had never been seen before.

After a long time, the genius of the Nine Caves slowly disappeared, the runes did not enter Zhou Tong's body, and everything returned to calm.
