Getting back to the subject, after handing over the matter of protecting the Dharma to Chen Nian, the Immortal Old Man immediately began to retreat to achieve breakthroughs in cultivation.

Compared to Taoist Taoist Tai Zhuo in the past, the Immortal Primitive Realm signpost where the Immortal Old Man is located is extremely secretive. It can be said that very few people know about it, so the security has to be increased a lot.

This time the Immortal Old Man's breakthrough could be said to have been much smoother, and no powerful enemy even appeared to block the way.

In this way, after the immortal old man had been in seclusion for about ten kalpas, he finally raised his aura to the limit and began to attack the realm of the Chaos Emperor.

"He's starting to break through."

When Chen Nianzhi saw this, he showed a somewhat dignified expression.

In the Immortal Primitive Territory, the disciples and grandsons of the Immortal Old Man also showed a bit of worry when they saw this.

It is extremely difficult to break through the Chaos Emperor. Even if the person in charge cultivates the nine divine forms, the probability of finally being able to break through is actually only half.

The method of physical body sanctification is more domineering, and the probability of breaking through the Chaos Emperor is greatly reduced.

Even if you cultivate the unique divine form, generally speaking, the probability of a successful breakthrough is only about 30% on average.

Seeing this, Emperor Black Abyss on the side said: "You don't have to worry, the immortal old man practices the immortal path which is best at defense."

"Coupled with the help of the Climbing Holy Pill, I think his probability of breakthrough is far higher than that of ordinary people, and the possibility of success should be extremely high."

Chen Nianzhi also nodded, if the probability of a person becoming a saint in the physical body to break through the Chaos Emperor is no more than 30%.

Then the immortal foundation of the immortal old man who is good at defense, the probability of a successful breakthrough should be no less than 50%.

Because the only immortal true form is tough and immortal and has extremely strong defense, the success rate when transforming into the chaotic god form is much higher.

Coupled with the Ascending Holy Pill that can increase the probability of breakthrough by 30%, the success rate of the Immortal Old Man's breakthrough is already extremely high, much higher than that of Taoist Tai Zhuo back then.

"Senior Immortal has a great chance this time, and he should break through to the realm of the Chaos Emperor."

Chen Nianzhi's thoughts flickered, and he suddenly heard a violent Hongmeng sound.

As a sound that destroyed the sky and split the universe sounded, the immortal old man suddenly ascended into the sky.

His whole body was entangled by the endless avenue of chaos, and he was surrounded by all the heavens and ten thousand ways and fell into the sea of ​​the avenue of chaos.

"It's done."

Seeing this scene, Chen Nianzhi was convinced.

As expected, the immortal old man rose and fell in the ocean of avenues, allowing the endless avenue of chaos to baptize his body, and finally, in the celebration of the infinite avenue, he cultivated the unique form of the god of chaos.

"Congratulations, fellow Taoist, for you have attained the enlightenment of chaos. I am very happy and congratulated."

"It turns out to be an immortal old friend. I didn't expect that you have already achieved a breakthrough."

"By becoming a saint in the flesh, Immortal Brother's strength will definitely make Xiaoke excited. It seems that there will be another top emperor in the Chiyang Hundred Domains."

After the Immortal Old Man broke through, waves of compliments came from the Chaos Avenue Sea.

Many Chaos Heavenly Emperors from the Chiyang Hundred Domain, and even those outside the Chiyang Hundred Domain, noticed the breakthrough of the Immortal Old Man through the changes in the Great Dao Sea.

Many Chaos Heavenly Emperors came to congratulate and took this opportunity to interact with the immortal old man.

The Immortal Old Man responded to everyone one by one, and then quickly withdrew from the Great Dao Sea and returned to the Immortal Primitive Realm.

Seeing this, Chen Nianzhi couldn't help but smile and said: "Congratulations, senior, this time I have achieved the realm of chaos. From now on, I can look down on the vast chaos."

"Hahaha."

The immortal old man laughed. As the saying goes, all under the Emperor of Heaven are ants. Although he was called the Emperor of Ban before, he was not the real Emperor of Chaos after all.

Now, his cultivation level has reached the realm of the Chaos Heavenly Emperor, and his strength is considered to be the top among the Chaos Heavenly Emperors.

If so, and the cultivation level breaks through the sub-sage realm, then it is barely qualified to involve the entire Chiyang Hundred Domains.

Then after setting foot on the Chaos Heavenly Emperor, he will have a place in the Chiyang Hundred Domains.

The Immortal Old Man has now succeeded in breaking through. As a leader among the Chaos Heavenly Emperors, he will also be a famous figure in the Chiyang Hundred Domains.

With this thought in his mind, the Immortal Emperor smiled and said, "Let's just talk about friendship as equals. There is no need for so many false courtesy."

Chen Nianzhi smiled, but did not struggle with the title.

He directly changed the topic and asked with a smile: "Senior, how do you feel about this breakthrough?"

"Variety……"

The Immortal Emperor pondered slightly, then tried his own strength, and couldn't help but smile and said: "The strength and means have improved a lot."

"But the biggest change is my defense."

Following the Immortal Emperor's eloquent words, Chen Nianzhi gradually understood the changes in the Immortal Emperor's strength after his breakthrough.

After breaking through the realm of chaos this time, the Immortal Emperor's power and methods have improved a lot, almost reaching the level of the ordinary Chaos Emperor.

But what he improved the most was his own defense.

Before the breakthrough, the Immortal Emperor's physical defense was probably about 50% stronger than the ordinary Chaos Emperor.

But now after the breakthrough, the Immortal Emperor's defense has increased several times from the original level.

Such a huge change greatly increased the physical defense of the Immortal Emperor, completely reaching the limit of the first realm of chaos.

In other words, the Immortal Emperor's physical defense at this time should be comparable to an invincible strong man at the Half-Step Hedao Realm.

Taken together, the combat power of the Immortal Emperor should be comparable to that of the top Chaos Emperor.

However, because the defense is too strong, even the invincible Emperor who is half-stepped in harmony will be difficult to completely suppress the Immortal Emperor.

Although the attack power is slightly worse, the Immortal Emperor's defense is too strong. Against the ordinary Chaos Emperor, it is completely possible to only attack but not defend, thereby gaining a greater advantage.

After understanding the strength of the Immortal Emperor, Chen Nianzhi couldn't help but breathe a sigh of relief.

With such a die-hard ally, Chen Nianzhi's safety will be more guaranteed when he returns to the Seven Domains of Nanyuan this time.

Thinking of this, Chen Nianzhi asked again: "Now that senior has broken through the Chaos Emperor, what are we going to do next in the Immortal Primitive Realm?"

The immortal old man's eyes moved slightly, and he immediately understood what Chen Nianzhi meant.

Because after breaking through the Chaos Heavenly Emperor, you can control the primitive realm across Chaos and reach the distant shore of Chaos.

Therefore, in the vast chaos, the primitive realms with the Chaos Emperor often gather together to jointly suppress a sea of ​​chaos.

Because in chaos, the security of the original domain alone is not guaranteed.

Even with the Chaos Emperor sitting at his command, once faced with the Supreme Hedao or multiple Chaos Emperors joining forces, this primitive domain has little ability to protect itself.

Therefore, many primitive domains will gather together, not only to suppress the vast and chaotic sea, but also to improve each other's ability to resist risks.

Although the seven regions of the South Abyss are at odds with each other, the major Chaos Emperors of the seven primitive regions have all concluded an eternal covenant.

Although this covenant is not very restrictive, once they encounter foreign enemies, the emperors of the seven regions of Nanyuan need to join forces to fight against the enemy.

This is also the key reason why the Seven Domains of Nanyuan can survive to this day, and even have some confidence in facing the Chiyang lineage.

The immortal old man also thought of this, he couldn't help but ponder for a moment and then said helplessly: "If the original realm of Xianhuan is still there, I may join the realms of Tianyuan."

"Unfortunately, the current Seven Territories of South Abyss have no close relationship with me, so I am hesitant to join them."

Chen Nianzhi nodded, but suddenly said: "If fellow Taoist don't want to join the Seven Realms of Nanyuan, why not temporarily join the Great Wilderness Ancient Realm."

"The Great Wilderness Ancient World?"

The immortal old man pondered slightly, and then said: "The ancient world of the Great Wilderness is not far from us, this is a good idea."

Speaking of this, the Immortal Emperor took back his thoughts, looked at Chen Nianzhi and said: "But this matter is not urgent. Let's wait until I send you back to the Seven Domains of Nanyuan first."

"That's fine."

Chen Nianzhi nodded. There are still about three hundred kalpas left before Tianlu Cave Heaven appears.

Next, he plans to return to the Seven Domains of Nanyuan first, but now the news that he has the Chaos Refining Vase has probably been exposed. It is indeed the best choice to have the support of the Immortal Emperor.

So he did not refuse and agreed to the idea of ​​the Immortal Emperor sending him back.

So next, the Immortal Old Man only slightly consolidated his cultivation, and then took Chen Nianzhi and Black Abyss Yasheng to the Seven Domains of Nanyuan.

Several kalpas passed by in the blink of an eye. When Chen Nianzhi returned to the Seven Domains of Nanyuan, he couldn't help but smile a little.

"After being away from home for nearly a hundred calamities, we are finally back."

Looking at the Seven Domains of Nanyuan in front of them, the three of them felt a rare joy in their hearts, feeling like they were returning home in rich clothes.

Returning to the Seven Domains of South Abyss this time, the Immortal Heavenly Emperor was able to set foot in the realm of the Heavenly Emperor. The Black Abyss Emperor's combat power was close to rivaling that of the Heavenly Emperor, and Chen Nianzhi also had the combat power at the Heavenly Emperor level.

Such a huge breakthrough caused a big change in the mentality of the three of them unconsciously.

They looked at each other, laughed, and then walked towards the primitive fairyland.

As a result, not long after walking, the immortal old man frowned slightly, and then said, "Come out, everyone."

There was a slight silence in the chaos, and after a moment two figures walked out.

One of these two people was shrouded in holy light, and the other was surrounded by evil spirits. They were both powerful and powerful Chaos Emperors in hundreds of regions.

"The Holy Emperor of Light, the Demon Emperor of Darkness."

Looking at the two people in front of him, Chen Nianzhi frowned slightly, showing a bit of surprise.

It turns out that these two people are the Chaos Holy Emperor and Chaos Demon Emperor from the Holy Demon Primitive Realm.
