Tianshu Pavilion, or called - Tianshu auxiliary management system.

This contains the treasure house of the wisdom of the entire Fourth World Dao civilization, a large number of immortal classics, and some powerful immortal research codexes, as long as Su Yang can think of the cultivation method, there is almost nothing that cannot be found in the Heavenly Book Pavilion.

Back then, Su Yang successfully took away the Heavenly Book Auxiliary Management System in the Heavenly Realm, which was equivalent to taking away the entire Heavenly Book Pavilion, and it was also equivalent to Su Yang taking away the wisdom essence of countless immortals in the entire Fourth World Dao civilization.

After that, Xiao Tiannao relied on the excellent and powerful system to turn the Tianshu auxiliary management system into a part of herself, including the Tiangong auxiliary management system and the flying auxiliary management system, so that she successfully completed a new upgrade and gave birth to her own soul.

When Xiao Tiannao has a soul, he is no longer an artificial intelligence limited to the world of the spirit net, but also has the qualifications to become a "human".

So, Su Yang designed a new body for Xiao Tiannao, so that she can be like a real "person", able to practice, able to grow, and able to enjoy all joys, sorrows, and sorrows.

At the same time, after Xiao Tiannao became a "human", she did not lose her own advantages, and her soul could directly control the spirit net world, and if necessary, she could also become an artificial intelligence to assist Su Yang.

Especially in terms of doppelgangers, the countless subsystems that are separated under the main system can continue to be used as artificial intelligence.

It's just that in the face of certain advantages, there are still certain flaws.

Because the soul is a very complex existence and has uniqueness, the rest of the subsystems of the small celestial brain are far less humane than the main system, and they are finally sluggish and dull, and they look very mechanical.

For example, at this moment, after Su Yang woke up Xiaotian's brain subsystem, the subsystem asked mechanically: "Daddy, is there anything I can serve you?" ”

This made Su Yang a little unaccustomed, after all, Xiao Tiannao's lively personality, in such a lonely environment, can be used as a companion of Su Yang, and sometimes it is quite heartwarming.

However, now Su Yang can't ask for so much, he can only wait for Xiao Tiannao to reach a certain level in the cultivation of the divine soul, and the subsystem is more like a doppelganger-like existence, and he can regain his vitality again.

And now, Su Yang could only use the functions of the subsystem, and ordered: "Search the Heavenly Book Pavilion, and find all the research codexes, materials, and exercises about the divine soul." ”

The subsystem of Xiaotian Brain replied programmatically: "I am happy to serve Daddy, please receive information." ”

After speaking, the information transmitted by the subsystem appeared in Su Yang's consciousness, and a large number of immortals' research on the divine soul were presented in Su Yang's consciousness in a variety of ways, and he knew it in his heart.

It's just that there are too many of these studies, and it is difficult for Su Yang to read them all in a short period of time, so he can only calm down, analyze and study them one by one, and understand them one by one.

This study is three years!

With Su Yang's reading speed, it actually took three years to be able to read it once, which was enough to show how huge the number of immortal classics and research codex in the Heavenly Book Pavilion was.

Especially after three years of reading, Su Yang only understands a general idea, and Su Yang does not have enough understanding at all for specific and deeper research and understanding.

At the same time, after reading it, Su Yang found that the Fourth Dao Civilization's cognition of the Divine Soul was obviously fundamentally different from the Seventh Cultivation Civilization.

In the cultivation system of the Fourth Dao Civilization, the Divine Soul is mainly to better use the laws of the Heavenly Dao, while in the Seventh Cultivation Civilization, the Divine Soul is understood as an upgraded version of the soul, and it is more about using some of the divine powers of the Soul Dao.

However, the way of application is different, but the understanding of the essence is the same.

Therefore, after thinking carefully, Su Yang ordered the subsystem of Xiao Tiannao to put away some of the information about the divine soul, leaving only more than 300 precious codexes for more careful study.

Among the more than 300 kinds of research codexes, Su Yang's choices were obviously targeted, and most of them were cultivation methods that involved soul splitting.

Among them, a cultivation method similar to speculation made Su Yang the most interested.

The name of this method is called "Thousand Souls Refining Heart Formula".

The Thousand Souls Refining Technique is a method of splitting the Divine Soul into a thousand individuals and a thousand individuals cultivating the Divine Soul at the same time, and when the right time comes to retract all of them, it is equivalent to completing a thousandfold of cultivation, and the Divine Soul has grown to an incredible height with this leap to an incredible height.

Obviously, this is a very whimsical cultivation method, if you can really succeed in cultivating with this, the cultivation speed of the cultivator in terms of divine soul is probably not much worse than that of the Hongmeng Town Divine Technique.

It's a pity that the idea is very good, but it's obviously not realistic, absorbing a thousand powerful divine souls at once, even if they are all split from their own true souls, this way of skyrocketing can easily hurt the divine souls.

Therefore, the guy who conceived such a wonderful method of cultivating the soul back then played himself to death on the first attempt.

However, because this method does have a certain degree of feasibility, and also has a certain genius idea, so Tianshu Pavilion included this method, but most immortals still think that it is too whimsical, and there are too many uncertain factors, until in the end, no one is willing to conduct further research.

But today, after tens of millions of years, Su Yang accidentally found such a set of exercises because of his needs, and he suddenly became deeply interested.

And Su Yang is obviously much stronger in level and experience than the unlucky immortal back then, so the cultivation method that this guy was not able to complete back then, Su Yang may not be able to complete.

At the same time, Su Yang also occupies another advantage, that is, the immortal arts recorded in the Heavenly Book Pavilion, and the research codex, he can read it at will, but the unlucky immortal back then was not as cool as Su Yang.

It's just that the Thousand Souls Refining Soul Recipe seems to be far from enough for Su Yang, and judging from the current situation, it is at least necessary to divide the soul in units of 100 million to be able to help Su Yang complete the exploration of the endless dark emptiness.

However, research is not a day's work, and Su Yang did not expect to have a result in a short period of time, what he needs now is a clear research direction, and then continue in this direction.

In this way, Su Yang began to develop and research around the "Thousand Souls Refining Heart Formula", and it took a full eighteen years to study it.

In the course of eighteen years, Su Yang finally succeeded in upgrading the Thousand Souls Refining Technique to the heights of Ten Thousand Souls, One Hundred Thousand Souls, One Million Souls, Ten Thousand Souls, and Ten Million Souls, and took this opportunity to successfully release 130 million Peerless Stone Satellites.

It's just that although the results are amazing, the results can't make Su Yang particularly satisfied.

Because the split soul cannot be cultivated as quickly as the main soul, it must take a long time to be able to grow a little, and this silk growth, the main soul is the time to take a breath, and it can be cultivated.

But even this insignificant trace, after accumulating to a terrible level, is still not to be underestimated.

For example, after Su Yang upgraded the Thousand Souls Refining Technique to the level of 100 million Soul Refining Techniques, after the 100 million souls returned to the same level, how much should the main soul grow?

Therefore, after learning more about the drawbacks inside, Su Yang suddenly felt that in fact, this is the real cultivation method, 100 million souls do not need to be too strong, too strong but the main soul is a little unbearable, but if the number is enough, it can be trickled for a long time, so that the main soul can be successfully fused without much impact.

At the same time, Su Yang also discovered that after integrating the unique meditation method of the Northern Black Emperor, the Ten Million Soul Refining Secret not only made the divine soul more stable, but also the refining of the will was also very amazing.

As a result, Su Yang combined the Hongmeng Town Divine Technique, the Northern Black Emperor Meditation Method, and the Ten Million Soul Refining Mind Technique, and began to create a new set of cultivation methods, which were suitable for the cultivation methods of the Little Heavenly Dao cultivation method.

And just like that, another fifteen years passed.

In the past fifteen years, Su Yang cultivated the Divine Soul while releasing the Split Soul while deducing new exercises, and after his continuous efforts, he finally succeeded in creating an unprecedented terrifying method.

The name says: One Billion Soul Transformation Divine Formula.

The One Billion Soul Transformation Divine Technique is a kind of special divine soul cultivation method that combines the Hongmeng Town Divine Technique, the Northern Black Emperor Meditation Method, and the Hundred Million Soul Refining Heart Technique, and combines the three divine soul cultivation methods as one.

First of all, this method uses the meditation method of the Northern Black Emperor to visualize a vast Heavenly Dao law.

For example, the cultivation method of the Northern Black Emperor's meditation method is to visualize the Heavenly Dao, so Su Yang also does the same, but what he visualizes is the life gene of the Little Heavenly Dao, and constructs a genetic model that is exactly the same as the ontology.

After that, Su Yang used the Hongmeng Town Divine Formula to cultivate, and used the 100 Million Soul Refining Secret to split the Divine Soul and carry out the initial primitive accumulation.

In this regard, the synergistic effect of the Hongmeng Town Divine Technique and the Ten Million Soul Refining Heart Technique is beyond doubt.

For example, the Hongmeng Town Divine Technique is among the civilizations of the past and present generations, and it is also an absolute top Divine Soul cultivation method, with which you can quickly accumulate enough Divine Soul.

Besides, after Su Yang took his method of splitting the soul of the soul, he abandoned the cultivation rhythm of splitting the soul in the back, and began to simply split the soul to create a billion souls.

In the end, it is the essence of Su Yang's entire Billion Soul Transformation Divine Technique, that is, the Billion Soul Dividing Soul returns to the same, lighting up the life genes of the visualization in turn, and then letting the Divine Soul transform into a structure equal to the life genes of the ontological body.

When the time comes, let the divine soul, which is highly unified with the ontology, complete a subtle combination with the ontology, and then the divine soul and the ontology will form a subtle combination, and the divine soul will be transformed into a small heavenly path of soul mode, and the use of itself will be better.

This is the Billion-Split Soul Transformation Divine Technique, a Divine Soul Cultivation Method that fully matches the cultivation method of the Little Heavenly Dao.

In other words, this is a Divine Soul cultivation method specially designed for the cultivation method of the Little Heavenly Dao, which has successfully made up for the weakness of the Little Heavenly Dao's cultivation in some aspects.

At that time, a powerful divine soul and a powerful law body, which is equal to the comprehensive and extreme sublimation of the soul and physical body, how powerful will it be, even Su Yang can't say it now.

All because, although Su Yang has now completed the division of the billion souls, because he needs to explore the reason of the endless darkness and emptiness, he can't recover all the billions of souls and try the feasibility of the last step.

At the same time, one billion soul points is not the limit, and Su Yang feels that there is still room for further improvement.

But just when Su Yang was about to continue his research to see if he could turn a billion into tens of billions, or even hundreds of billions, all of a sudden, Su Yang seemed to sense something, making him forget all the research for a moment, and suddenly opened his eyes and looked sharply in a certain direction.
