Longevity starts with learning

It took Chu Mu several days to come out of the blood cave, holding the jade slip, with the spiritual light still there, and he was still in a state of deep thought.

After a long time, he put down the jade slip, still in deep thought, and appeared from the blood cave in the garrison in a flash.

However, the garrison now is just a mere form.

The Tianyuancheng Garrison, which once covered an area of ​​more than a thousand acres, had long been transformed by him into a large-scale prison.

In this prison, some strange monsters and beasts he collected through Changsheng Sect and Tianyuan City, as well as a large number of demons and monsters, were imprisoned.

The prison is divided into four floors.

From top to bottom, demons and monsters of the first to fourth levels are imprisoned.

Although it has only been more than ten years, there are nearly six hundred demons and monsters imprisoned in this prison, including four fourth-level demons!

The prison has no name, and Chu Mu has no time to name it. The entrance is the original gate of the garrison.

After his transformation, it became the only entrance to the prison.

Pushing open the two heavy diamond doors, Chu Mu saw a deep stone path leading to the prison.

Passing through this stone path, it is the first floor of the prison. The prison is not gloomy at all, and is even very spacious and bright.

Except for a few empty cages, the three hundred cages are all filled with various strange monsters and beasts.

Although the first-level cultivation is insignificant.

But these monsters and beasts, without exception, have their own peculiarities.

This peculiarity is the fundamental reason why he built this prison.

All bloodlines, monsters, demons, and even demons must have magical powers.

Although magical powers are similar to the techniques of immortal cultivators, they often have all kinds of incredible mysteries that go beyond the techniques.

After all, the techniques of the immortal cultivators are just a separate system based on spiritual energy.

The bloodline supernatural power is rooted in the bloodline and is a mystery with the power of the bloodline as the core.

Each bloodline has different mysteries, so the supernatural powers rooted in the bloodline often have unique mysteries.

However, this is only limited to high-level bloodlines. The higher the level of the bloodline, the more mysterious the bloodline supernatural power is. If the bloodline is rubbish, the bloodline supernatural power is often not much stronger.

Even if there are exceptions, most of them have reasons, and it is impossible for rootless duckweed to mutate.

As early as when he first arrived at the Hanhai Xiuxian world, he had a lot of glimpses of bloodline supernatural powers.

However, due to his limited cultivation, he could only peek through the fog.

And as he stepped into the realm of Yuanying and stood at the top of this world, under the blessing of the great power of heaven and earth, the mystery of bloodline and the secret of bloodline supernatural power were finally barely unveiled in front of him.

However, with the improvement of his cultivation, ordinary bloodline magical powers no longer have much meaning to him.

And the bloodline magical powers that can catch his eye are mostly only found in big monsters or big demons, and it is impossible for him to concentrate on peeping.

Fortunately, Wangcai took over another body and was reborn. His bloodline is strong, and his awakened magical powers are extremely mysterious.

However, the arrival of this demon catastrophe also involved too much of his energy and completely disrupted his plan.

All along, there has not been much time to peek at the mystery of Wangcai's magical powers.

With the current situation, he would not have the energy to peek at the mystery of Wangcai's bloodline magical powers.

But the speed at which the situation deteriorated was too fast.

In just a dozen years, the changes in the world can be described as earth-shaking.

The hope is so slim that even with his mind, he can't help but hesitate, and even more hesitant!

If there is no hope, how can we stick to it?

Everything is prepared, and if it is not prepared, it will be abandoned. This has always been his code of conduct.

In such a situation, he naturally needs to make some plans for himself.

After all, regardless of the demon catastrophe in front of him, the quality of the demon world has been steadily improving over the years.

As the quality of the world improves, the limit of the power that can be accommodated will inevitably increase accordingly. This is also an unquestionable rule of heaven and earth.

But it goes without saying that with the demon world's rejection and disgust of cultivators, even if the demon world can accommodate the existence of the fifth level, this fifth level is definitely only for demons, not cultivators, not monsters!

Judging from the current situation, the quality of the demon world is steadily improving. One day in the future, the existence of fifth-level demons is definitely not a fantasy.

He even speculated that the improvement of the quality of the demon world is preparing to welcome the arrival of that terrifying existence.

When that time comes, the destruction of the ancient cultivation world will inevitably reappear.

And the current cultivation world is not connected to the upper world, and it is unlikely that there will be great supernatural powers from the upper world.

When it really comes to that last resort, there is no hope of ascending, the world does not tolerate him, and the fifth-level demons exist, what can he do?

His only escape route might be in the chaotic void.

But...

How can a mere Nascent Soul Realm survive in the unknown chaotic void?

Let alone the terror that is everywhere in the endless chaotic void, the environment of absolute spirituality alone is enough to be fatal.

The chaos is boundless, and the Nascent Soul Realm cannot absorb the endless and majestic energy in the chaos. Even if he prepares more spiritual stones, it is meaningless.

After all, according to his experiments, unless it is a self-circulating top-grade spiritual stone, low-level spiritual stones, once exposed to the chaotic void, will be assimilated and annihilated by the chaotic void.

This phenomenon is similar to the irreversible assimilation of low-level energy in a high-level energy environment.

And the best spiritual stone...

According to the relevant records he read, one best spiritual stone can definitely meet the needs of restoring mana in the Nascent Soul Realm, but the speed of absorbing the energy of the Chaos Void to achieve self-circulation and restore spiritual energy is not fast. It may be okay for emergency use, but if you want to rely on it as the only energy support for entering the Chaos Void...

One or two best spiritual stones are definitely not enough.

Chu Mu estimated that the reason why the leader of the Changsheng Sect dared to enter the Chaos Void back then was probably more than one best spiritual stone.

Given the current situation in the world of immortal cultivation, it is completely unrealistic to rely on best spiritual stones.

In other words, it is not realistic to rely on external objects.

After all, the dangers of the Chaos Void are too unknown, and only when the great power lies in oneself can it be safer.

His idea is exactly this.

If he can absorb and refine the higher-level energy of the Chaos Void to replace the role of spiritual energy...

Does that mean that he can survive in the Chaos Void with ease?

Even if he really had to, he could retreat into the Primal Chaos Void, which was much more reliable than the Immortal Sect Master who relied on the top-grade spirit stone to pursue a slim hope.

Moreover, he had a most important guess.

In this world of immortal cultivation, the power limit of immortal cultivators was firmly limited to the Nascent Soul Realm.

But if he escaped from the influence of the world of immortal cultivation and went deep into the Primal Chaos Void, could he avoid the shackles of the world's power limit?

Although this seemed to be a far-fetched talk, if he could absorb and refine the high-level energy of the Primal Chaos Void, he could completely escape from the influence of the world's halo, completely escape from the world of immortal cultivation, go deep into the chaos, and break through his cultivation...

At that time, for him, perhaps he could truly enter the world to fight against demons, and retreat from the world, go deep into the chaos, and avoid disasters...

And the only key is how to refine the energy of the Primal Chaos Void.

Over the years, he has studied Wangcai's devouring magical power, built this prison, and suppressed hundreds of demons and monsters, all for this reason.

These hundreds of demons and monsters that he captured and suppressed, no matter what their cultivation level was, all had devouring bloodline magical powers.

Devouring magical powers are second to none in refining heterogeneous energy, and they also have the mysterious power of large-scale devouring energy, refining energy, and feeding back to themselves.

He himself also has the Great Sun True Fire and Sword Intentions, which are also the means of refining heterogeneous energy, and are not inferior to devouring magical powers.

Moreover, whether it is the perception of sword intentions or the spiritual fire transformation of the Great Sun True Fire, they also have a lot of room for growth...

These three... if combined together...

Although it seems a bit far-fetched, it does not seem to be completely a fantasy for him.

After all, his sword intention system and fire attribute immortal system were originally prepared to merge into one before he formed the pill.

Although he missed the chance to merge the Dan back then, he has been thinking about the fusion of the two over the years, and has conducted many experiments, so he has a certain foundation.

And the existence of the Devouring Divine Power may also serve as an opportunity to merge the Fire Attribute Immortal Dao System and the Sword Intention System.

An opportunity to completely integrate his own practice system...
