With the help of the Chaos Observation Mirror, Chen Nianzhi continued to perfect the method of the True Spirit Immortal Hidden.
Moreover, Chen Nianzhi also further simplified the methods of the three major immortal treasures based on the existing methods of the three major immortal treasures.
He simplified the True Spirit Immortal Treasure into the Nine True Spirit Immortal Treasures, and the difficulty and conditions for cultivating the Nine True Spirit Immortal Treasures were much lower than those of the Ten True Spirit Immortal Treasures.
However, in this way, the potential of those who achieve Taoism through the Nine Great True Spirits and Immortal Treasures will be greatly reduced in the future, far less than those who have made breakthroughs in the Ten Great True Spirits and Immortal Treasures.
However, it is indeed too difficult to break through the Ten Great True Spirit Immortal Treasures, and the bottleneck is several times larger than that of the Nine True Spirit Immortal Treasures. This simplified version is more suitable for sacrificing our Dao Emperor.
Getting back to the subject, after perfecting the three true spiritual secrets, Chen Nianzhi once again used the Chaos Observation Mirror to examine his body. After confirming that there was no flaw, he woke up from seclusion.
At this time, a period of calamity had arrived, and everyone else was also teleported out of the ancient mirror. Everyone was smiling, and they seemed to have gained a lot.
"The time has come, it's time for you to go to the next level of heaven."
At this time, the cave spirit appeared again and moved them to another heaven in the blink of an eye.
After a while, Chen Nianzhi came back to his senses and found that he had appeared in another majestic sky.
Compared with the boundless and heavy sea of Shen Yuantian and the infinite order of the Dao of Zhudao, the sky here is filled with chaotic divine fire, resembling a vast ancient immortal furnace.
"Refining Immortal Heaven."
At this moment, Black Abyss Yasheng suddenly spoke, showing a hint of surprise.
Pan Huang, Chaos Dragon Lord, and even the Ancient Demon Ape and others on the side also showed a hint of ecstasy.
Chen Nianzhi's eyes moved slightly. Compared to Shen Yuantian, who sharpened his body, and Zhu Daotian, who understood the great way, this Immortal Refining Heaven is a person who has become a saint in the flesh, and has the most coveted treasure land of the supreme saint.
The so-called Immortal Refining Heaven is composed of the three treasures.
These three treasures are the Immortal Refining Furnace, Chaos Immortal Fire, and Chaos Fire Veins.
Among the three treasures, the Immortal Refining Furnace is a middle-grade Chaos Spiritual Treasure, and it is the most precious treasure in Tianlu Cave.
It is said that the complete body of the Immortal Refining Furnace is a powerful top-grade Chaos Spiritual Treasure, but its grade fell due to the inexplicable disappearance of the weapon spirit.
The Chaos Fairy Fire was also the first divine fire in Tianlu Cave in the past, possessing the terrifying power to burn the Chaos Emperor.
As for the Chaos Fire Vein, it is also a middle-grade Chaos Ancestral Vein, and one of the three mid-grade Chaos Ancestral Veins controlled by Tianlu Dongtian.
Looking at the Immortal Refining Heaven in front of him, the Chaos Dragon Lord couldn't help but said with great joy: "When the Heavenly Furnace Cave was so powerful that it shocked the heavens, it created nine major Chaos Cave Heavens."
"And among these nine caves, the Immortal Refining Heaven is the most respected, and is known as the leader of the nine caves in Tianlu."
"This place is a treasure of supreme opportunity, and it may be related to our chance of enlightenment."
When Chen Nianzhi heard this, he couldn't help but become more curious, and asked with some confusion: "I also heard that Immortal Refining Heaven is a treasured place for cultivation, but I don't know what is so amazing about this place?"
"Ignorant."
Chaos Dragon Lord sneered, and then said calmly: "The core of Immortal Liantian is deep in the Chaos Fire Veins."
"It is said that every time the Heavenly Furnace Cave is opened, the Immortal Refining Furnace will appear in the deepest part of the Chaos Fire Veins."
"Once you find that Immortal Refining Furnace, you can use the power of the Immortal Refining Furnace to absorb the power of Chaos Fire Veins and Chaos Immortal Fire to refine your body, and finally complete the ultimate transformation in the Immortal Furnace."
"Since ancient times, people who have been refined in the Immortal Refining Furnace have often been either alive or dead. If they succeed, they will cultivate their unique true form, and if they fail, they will be completely destroyed in the flames."
When Heiyuan Yasheng heard this, he also nodded and said: "As far as I know, if you break through in the Immortal Refining Furnace, your chances of being promoted to the Chaos Emperor can be increased by at least 10%."
"However, every time Tianlu Cave is opened, the Immortal Refining Furnace is one of the biggest opportunities, but not many people dare to break through it."
When Chen Nianzhi heard this, he couldn't help but nodded slightly.
This Immortal Refining Furnace is obviously a treasure trove for breaking through to the Chaos Heavenly Emperor, because breaking through to the Chaos Heavenly Emperor itself has only one choice, either complete destruction and death, or directly breaking through to the realm of the Chaos Heavenly Emperor.
Since it was either life or death, it was indeed a rare opportunity to use the power of the Immortal Refining Furnace to increase the chances of breaking through the Chaos Emperor by 10%.
Thinking of this, he said with a bit of solemnity: "It seems that this Immortal Refining Heaven is indeed the most dangerous and the place with the greatest opportunities."
After saying this, Chen Nianzhi, Heiyuan Yasheng, and Panhuang had already stood together, preparing to go to the Immortal Refining Heaven together.
"snort."
Seeing the alliance of three people, the Chaos Dragon Lord couldn't help but snorted coldly, but there was a trace of solemnity in his eyes.
However, the Scarlet Phoenix Saint shook her head and said calmly: "In the Heavenly Furnace Cave, strength alone is not enough, you must also have enough opportunities."
After saying this, the Red Phoenix Saint did not hesitate and headed towards the chaotic fire veins deep in the Immortal Refining Heaven.
Everyone else also moved forward one after another, flying over with a bit of solemnity.
When Chen Nianzhi saw this, he couldn't help but take a deep breath, and then headed towards the Chaos Fire Veins.
After arriving in the Chaos Fire Vein, Chen Nianzhi discovered that this was a terrifying forbidden land filled with Chaos Fire.
There are actually as many as thirty-six types of Chaos Fire here, each of which has reached the level of the Chaos Heavenly Emperor. It was obviously jointly arranged by the Chaos Heavenly Emperors from Tianlu Cave in the past.
Each of these thirty-six terrifying fires of chaos has the terrifying power to burn the Emperor of Heaven. Even if it is enlarged to the entire chaotic ancestral line, it has extremely terrifying power.
Chen Nianzhi led Panhuang and Black Abyss Ya Sheng forward, followed behind him were the Ancient Spirit Emperor and Tianhuang Quasi-Emperor.
But just after reaching the halfway point, the Ancient Spiritual Emperor and the Quasi-Emperor Tianhuang stopped moving forward. The Ancient Spiritual Emperor sighed and said: "The fire of refining immortals here is specially made to temper the Emperor of Chaos."
"We have insufficient cultivation and have no chance to break through to the realm of the Emperor of Heaven, so we will no longer go deep into it."
Seeing this, Chen Nianzhi couldn't help but nodded.
He knew very well that the Tianhuang Quasi-Emperor and the Ancient Spiritual Emperor were not strong enough, and even if they had the opportunity, they would not be sure to accept it.
Fortunately, even if it is only the peripheral Immortal Refining Fire, it is a top-quality cultivation treasure for them, and it may be able to promote their cultivation of the Great Dao.
Thinking of this, Chen Nianzhi said goodbye to the two of them and said, "In that case, then you can practice cultivation in the periphery."
"Tianlu Cave Heaven's lineage pays attention to opportunities. This Chaos Fire Lineage is a treasure land. Even if it is just on the periphery, it will breed a lot of treasures. Maybe you can also gain something."
The two of them nodded, and that day Huang Quanhuang smiled and said: "Our background has grown a lot recently, and we may be able to cultivate the eighth divine form with the help of the Immortal Refining Fire."
"You continue walking, don't worry about us."
Chen Nianzhi nodded, said no more, and continued walking towards the depths of Immortal Refining Heaven.
Similar to Shen Yuantian, there are many treasures in this Immortal Refining Heaven, the most common of which are various fire-attribute treasures bred by the Chaos Fire Vein.
These rare treasures were of different grades, but most of them were at the level of Hunyuan rare treasures. Chen Nianzhi kept moving forward and took advantage of the situation to collect a lot of them.
However, he did not delay, and soon arrived at the core of Immortal Refining Heaven.
But in the deepest part of the Chaos Ancestral Veins, a huge volcano was filled with endless lava. On top of the lava was a ball of immortal Chaos Fairy Fire, and above it was a fairy furnace.
The moment he saw the immortal furnace, Chen Nianzhi's expression suddenly changed, and he couldn't help but reveal a hint of surprise.
"Immortal Refining Furnace!"
Black Abyss Yasheng on the side noticed something unusual and couldn't help but nodded and said: "This is the Immortal Refining Furnace, but is there anything unusual about it?"
Chen Nianzhi didn't answer, but he couldn't help but have thoughts in his mind.
He originally thought that the Immortal Refining Furnace in Tianlu Cave had the same name as the Immortal Refining Furnace in Ziyin Realm.
But at this moment, Chen Nianzhi suddenly discovered that the Immortal Refining Furnace in front of him was almost exactly the same as the Immortal Refining Furnace in Ziyin Realm.
The Immortal Refining Furnace of Ziyin Realm is copied from the Immortal Refining Furnace of Immortal Lord Ziyin.
"Could it be that Immortal Lord Ziyin of the past, the Immortal Refining Furnace in his hand was also a replica of this Immortal Refining Furnace?"
"Could it be that the former Immortal Lord Ziyin was related to Tianlu Cave Heaven?"
Chen Nianzhi was filled with doubts, but he couldn't figure out the cause and effect between the two, so he could only suppress his thoughts.
So Chen Nianzhi retracted his thoughts and looked around again, only to find that dozens of top sub-sages had gathered around him.
Each of these sub-sages are people with astonishing combat power. Almost all of them are Wuji sub-sages who have cultivated the nine true spirit divine forms, and there are even some who have cultivated the only divine form.
At this moment, everyone present looked at the Immortal Refining Furnace in front of them with a hint of covetous expression.
At this moment, a peerless genius who had cultivated the nine great divine forms came out and looked at the Immortal Refining Furnace.
"The Immortal Refining Furnace can refine the nine divine forms and fuse them into a single divine form. It can also increase the certainty of breaking through the Heavenly Emperor by 10%. It is one of the biggest opportunities here."
"I just don't know if any of you would dare to try this immortal refining furnace."
The expressions of everyone present changed slightly, and no one dared to be the first to walk up. After a long time, a burly man came out.
"It's the Quasi-Emperor Shi Ling."
Panhuang opened his mouth and said with a bit of solemnity: "The Quasi-Emperor Shi Ling has cultivated into the nine divine forms, and is only one step away from challenging the Heavenly Emperor. He ranks sixty-seventh among the sub-sages of Chiyang Baiyu."
Chen Nianzhi nodded, showing a hint of surprise.
There are countless heroes in the Chiyang Hundred Domains, and the number of sub-sages exceeds six thousand. The Stone Spirit Quasi-Emperor can rank sixty-seven, which shows that he is by no means weak among the Wuji sub-sages.
"Everyone, Lao Chan wants to use this precious land to cultivate his only true form. If he fails and falls here, I hope you can let Lao Chan's disciples go."
The Stone Spirit Quasi-Emperor said this, stepped directly into the Immortal Refining Furnace, and began to attack the only true form realm.
Seeing this scene, everyone present whispered, and many people showed solemn expressions.
Cultivating the only true form is an act of progress and no retreat. If it fails, it may lead to destruction.
But if he breaks through in the outside world and leaves enough backup, there is at least a chance of recovery. But once he dies in this immortal furnace, his soul will be completely gone.
"Do you think he can succeed?"
Black Abyss Yasheng spoke with a somewhat solemn expression.
Panhuang pondered for a moment, and then said: "The average blessing of the nine true spirit forms of Quasi-Emperor Shiling is only about 60 to 70%."
"With such a foundation, if we try to break through in the outside world, the probability of success is probably no more than 20 to 30 percent."
"Even if there is an Immortal Refining Furnace here to help, the success rate is only 40% at most."
Saying this, the Immortal Refining Furnace has been completely covered, the endless Immortal Refining Fire is boiling, and the extremely violent flames are burning everything.
Chen Nianzhi could clearly feel that the flames were enough to burn the Chaos Emperor, which was probably far beyond the limit that the Quasi-Emperor Shi Ling could withstand.
"I'm afraid I'm going to fail."
Chen Nianzhi spoke slowly, showing a hint of regret.
Sure enough, after the Immortal Refining Furnace trembled for a while, it finally calmed down with a violent roaring sound.
But when the lid of the Immortal Furnace flew up, infinite life essence flew out of the Immortal Furnace. All these essences were integrated into the chaotic fire veins, turning into extremely pure original power.
Everyone present understood that this original power was transformed into the flesh and blood of the Great Dao and the Stone Spirit Quasi-Emperor, and it was also the source of the Chaos Fire Vein that gave birth to all kinds of rare treasures.
"Failed."
Everyone present spoke, and each one showed a hint of sadness.
The path of cultivation for those who have become saints in the physical body is too overbearing. Once they fail, they will be completely destroyed. Most of the people present are those who have become saints in the physical body.
What happened to the Quasi-Emperor Shi Ling today may also become their future.
Immediately, many sub-sages left one after another, and in the blink of an eye, about 30% of them were gone.
The remaining sub-sages all looked solemn, but no one dared to step inside to practice.
"Since you don't dare, let me give it a try."
It was at this time that a gorgeous woman walked out of the crowd. The woman was wearing a cyan gauze skirt, and her appearance and cultivation seemed to be extremely powerful.
But what surprised Chen Nianzhi was that this woman did not seem to be a person who became a saint in the flesh, but instead took the path of being a master.
Panhuang frowned slightly and said in surprise: "It's her."
"You know this person." Chen Nianzhi said with some confusion.
Panhuang nodded, and then said: "Her Taoist name is Qingxu Fairy. She is a famous fairy in the Chiyang Hundred Domains. She follows the path of the Palm Tao. It is said that she has already cultivated the Nine Divine Forms."
"When she comes here today, I'm afraid she has obtained the beginning of chaos, and is only one step away from breaking through."
Chen Nianzhi nodded when he heard the words. The probability of breaking through the Chaos Emperor for those who have mastered the path of cultivating the Nine Divine Forms will not be less than 50%.
If she could obtain another Chaos Elixir, the possibility of this Qingxu Fairy becoming enlightened could even reach 70%.
In this case, if you venture into the Immortal Furnace Cave to break through, the success rate of Fairy Qingxu to break through the Emperor of Chaos should be no less than 70%.
Breaking through the Chaos Emperor has no way of advancing or retreating, and the 70% chance is enough to make him risk everything.
As expected, after the Qing Xu Fairy stepped into the Immortal Refining Furnace, she immediately began to refine the Chaos Beginning Qi to break through to the realm of the Emperor of Heaven.
With the help of the Immortal Refining Furnace, Fairy Qingxu's breakthrough is almost a matter of course.
Finally, under the refining of the infinite fire of chaos, the innate avenue she mastered completely completed its transformation, and almost became the avenue of chaos.
"Buzz——"
In an instant, the huge Immortal Refining Furnace was opened.
The Qingxu Fairy stepped up to the sky, her demeanor and magnificence were incomparable, and she had already stepped into the realm of the Emperor of Chaos.
"I've seen the Immortal Saint."
A newly promoted Chaos Immortal was born, and everyone present did not dare to neglect it. Even those who had cultivated their only god form bowed and bowed.
The Qingxu Fairy smiled, glanced at everyone with a smile, waved her hands and said, "Fellow Taoists, I just want to take the first step."
"I'll see you again in the chaos tomorrow."
Tianlu Cave Heaven did not allow the Emperor of Chaos to remain on this day. After finishing her words, Fairy Qingxu opened the void with a flick of her sleeves and disappeared into Tianlu Cave Heaven.
Until this moment, everyone present looked either surprised or happy.
Some were surprised, some were worried, and some showed a hint of jealousy. It was obvious that everyone present was quite envious and jealous of Qingxu Immortal Saint's breakthrough.
So next, several people stepped into the Immortal Refining Furnace one after another, hoping to break through their own cultivation.
It's a pity that they all failed and were destroyed by the fire. All their cultivation turned into life essence to nourish the world.
When Chen Nianzhi saw this, he vaguely understood in his heart.
According to his estimation, the Immortal Refining Furnace in its heyday should be able to increase Ya Sheng's confidence in breaking through the Chaos Emperor by 20%, and a failed breakthrough would not burn him to ashes.
It's just that because the weapon spirit disappeared and the grade dropped, the Immortal Refining Furnace was unable to fully control the intensity of the flames, so these sub-sages were completely burned into ashes.
The Immortal Refining Furnace in its prime state should be a top-grade Chaos Spiritual Treasure of incredible value.
It can increase the certainty of breaking through the Chaos Emperor by 20%, or cultivating the unique god form, and there is no side effect of completely incinerating the strong person if it fails.
Thinking of this, Chen Nianzhi couldn't help but glance at Black Abyss Yasheng, and then said: "This immortal refining furnace is dangerous, are you sure that senior can withstand it?"
"I'm not sure I can resist it for long."
Black Abyss Yasheng shook his head, and then said: "However, I have already cultivated the Chaos Divine Form, and have completely mastered the nine major Divine Forms. The certainty of breaking through the only Divine Form is extremely high."
"With the help of the Immortal Refining Furnace, cultivating the unique divine form is just a matter of course."
After the words fell, Black Abyss Ya Sheng stepped directly into the Immortal Refining Furnace without any hesitation.
As Heiyuan Yasheng stepped in, Chen Nianzhi immediately became serious and began to observe with all his strength.
In fact, as Black Abyss Saint expected, Black Abyss Saint's breakthrough to the only divine form this time was just a matter of course.
Under the refining of the Immortal Refining Furnace, Black Abyss Yasheng began to break through with the help of the flames of the Immortal Furnace.
In the process of breaking through, he took advantage of the situation to refine the Mother Spring of Chaos, completely supplementing the eight divine forms to a 100% increase, and then completed the final fusion.
In the end, with the Chaos God Form as the core, he completely refined the power of the eight great God Forms and built a single most powerful God Form.
