Longevity starts with learning

Chu Mu stared at the direction of the space crack, his eyes dim and his expression inexplicable.

After a moment, he suddenly looked up at the sky. That day, his palm crossed the sky, blocking the hundred-foot ancient spear for him and saving him from a dead end...

What the intention was, it was still unknown.

But when he refined the Heart of the Demon Realm, he felt that he was almost in control...

Everything he said and did in the secret realm, as long as the master of the secret realm wanted, there was no doubt that everything must be under the control of the master of the secret realm.

Whether it was when he first entered the secret realm, or now he was wandering around the secret realm in secret, it would be the same.

No matter what, at least from the current point of view, the mysterious dragon robe man had no ill will towards him.

Chu Mu looked around the surrounding magma sea of ​​fire that had already quieted down, pondered for a while, and jumped up, the red knife light flashed, and then sank into the sky again.

This time, it was not like wandering around aimlessly like before, but with a clear goal, going straight in the set direction.

About a day later.

The mountain peaks towered like sword blades, reflected on the lake surface, ripples surged, like water waves caressing the sword edge.

The memories that were already quite distant in memory have slowly merged with reality.

Chu Mu looked around for a while, took a step forward, and the next moment, he was suspended on the lake surface. Following the direction in his memory, Chu Mu walked in front of the lake.

Finally, he stopped in the middle of the lake, his figure flashed, sank into the lake, and rushed to the bottom of the lake. In just a moment, the mountains at the bottom of the lake came into view.

The breath of the second-level monster simulated by the Qi Tian Dan was enough to pass unimpeded in this secret realm, at the bottom of the Xijian Lake.

After wandering in the secret realm for several months, he could basically confirm that there seemed to be no monsters above the second level in this secret realm, for some unknown reason.

The highest cultivator was only at the second level.

Even if his injuries were not healed, he was definitely not something that an ordinary second-level monster could stop.

Along the way, the monsters at the bottom of the lake retreated one after another.

The tranquility at the bottom of the lake seemed to be completely broken with the arrival of this foreign "second-level monster".

The faint roars seemed to be questioning and testing this strange second-level monster.

There were even stubborn second-level monsters that attacked him brazenly.

But after he killed an unknown second-level monster with thunderous means, the turmoil at the bottom of the lake seemed to calm down quietly.

Those second-level monsters at the bottom of the lake that provoked and tested him also became honest in an instant in the face of the threat of death.

Chu Mu rushed along the bottom of the lake, walking and stopping in the remaining ancient battlefield. After wandering around for a while and collecting a large number of soul-condensing stones left by ancient puppets, Chu Mu looked at the mountains at the bottom of the lake.

Following the route in his memory, he walked all the way for about a quarter of an hour, and after turning around in the mountains at the bottom of the lake of varying heights, Chu Mu finally stopped in front of a stone wall full of various shellfish.

The stone wall was not much different from what he had seen before, except for a thick layer of shellfish debris.

Chu Mu stared at it for a moment, and couldn't help sighing when he thought back to the past.

He left this place that year, but he always thought about it.

Who would have thought that after the passage of time, he would return to this place again.

He sighed for a long time, as if he had just come to his senses, raised his hand and wiped it, and a jade slip from the Xiandao Sect floated in his hand.

Just as he had seen that year, as the jade slip emerged, the stone wall in front of him seemed to be affected by something, the stone wall trembled, the piled shells fell, and then a groove the size of a jade slip also appeared on the stone wall. The jade slip was placed in the groove, fitting perfectly.

He placed the jade slip in the groove, and a faint spiritual light flashed. The next second, the original stone wall turned into a portal with fluorescent light flashing.

The fluorescent light flashed, and it was a fluorescent white.

He tried to touch and perceive it with his spiritual sense just like before, but it was still an invisible barrier. With his current cultivation, it was also difficult to see the slightest bit of it.

Chu Mu hesitated a little. In the secret realm, he could still deceive the world with the Heaven-Deceiving Pill.

After all, according to what he knew from refining the Heart of the Demon Realm in the Demon Realm, the so-called secret realm rules should only be the existence of the controller of the secret realm, forcibly embedded in the secret realm.

This kind of rule does not belong to the scope of the secret realm itself. It is limited by the cognition of the rule maker, and naturally it cannot be infallible.

For example, since the existence of the "Heaven-Deceiving Pill" can deceive the world, it means that the existence of the "Heaven-Deceiving Pill" is very likely not within the recognition range of the "pseudo-rules" of this secret realm.

But... the Heaven-Deceiving Pill can deceive the "pseudo-rules" of this secret realm, but if it goes to the inheritance hall, to the illusory world built by the Immortal Dao Sect, whether it can continue to deceive the world is obviously unknown.

Based on the "refining the false into the true" that he saw in the illusory world, the inheritance place of the hundred arts of cultivating immortals, and the storage of countless knowledge and information, the possibility of continuing to deceive the world seems... not great.

Chu Mu pursed his lips and hesitated slightly.

Just as he hesitated, the calm fluorescent portal suddenly flickered. He subconsciously alerted, but then, an irresistible suction suddenly enveloped him.

He subconsciously retreated, regardless of his injuries, he burst out his cultivation, but it was meaningless.

The feeling of powerlessness surged into his heart again.

Then, under the suction, he uncontrollably sank into the fluorescent portal. With a dizzying feeling, he landed on the ground again. The place he was in was a white world that was quite familiar to him.

Chu Mu couldn't hide his surprise and looked back subconsciously. The fluorescent portal was gone.

He looked around, his eyes full of vigilance.

"I allow you to stay here for one year. After one year, you will go to the junction of the two realms for me and set up this formation."

At this time, a sound suddenly reached his ears.

Immediately afterwards, before Chu Mu could react, the billowing thick fog in the inheritance hall slowly dissipated.

The tests that were supposed to exist seemed to have disappeared.

Not far in front of Chu Mu, a ray of light flashed, and a storage talisman floated down, finally hanging in front of Chu Mu.

Chu Mu was slightly startled and looked around the main hall. There was no change from what he saw back then. It was still the inheritance hall. On the high platform, the huge Skymark crystal still stood majestically.

The sound was very clear, but the source of the sound could not be found.

Chu Mu pondered for a moment, hesitated for a while, and then silently held the storage talisman hanging in front of him in his hand.

His spiritual sense penetrated into the small storage space, and a set of array equipment appeared.

Beside it, there is a jade slip.

Chu Mu raised his hand and the jade slip levitated. He carefully checked the jade slip to confirm that there was nothing abnormal, and then he tried to use his spiritual consciousness to check.

The information recorded in it, as the spiritual consciousness penetrates, appears in the spiritual perception like flowing water.

There was a torrent of information, but in the end, the dense torrent of characters actually converged into five simple characters.

"Nine Dragon Divine Fire Formation!"

After the consciousness was fixed for a moment, these five simple characters suddenly changed and surged.

There seemed to be a roar in the dark. Under this roar, these five characters shattered into pieces and turned into a sea of ​​fire that filled the sky.

In the sea of ​​fire, the boundless flames gathered together and actually condensed into nine red fire dragons.

The roar of the fire dragon nearly covered the sky and the sun.

A pair of emotionless dragon eyes suddenly froze during the roar, and they all looked at Chu Mu fiercely.

boom!

There was another roar, a fiery roar, and the sea of ​​​​fire surged across the sky and seemed to burn the sky and destroy the earth.

The overwhelming torrent of information evolved again and poured into Chu Mu's sea of ​​consciousness.

But at this moment, it was just the illusory momentum of the fire dragon, and the demonic erosion spreading in his body, at this moment, it was as if he had encountered a natural enemy!

He calmed down in an extremely strange way, and the maggot-like erosion of his tarsal bones disappeared instantly without a trace.

The real fire of the sun suspended in the dantian also surged suddenly at this moment, as if unwilling to be outdone, it wanted to compete with the divine fire for glory.

Chu Mu suppressed the fear in his heart, kept his mind tight, and silently endured the impact of this forbidden message.

In about a quarter of an hour, the torrent of information seemed to have been instilled. The jade slips were broken. Chu Mu seemed not to notice, his eyes were closed, and he was still sorting out the torrent of information that had been instilled in the sea of ​​consciousness.

More than half an hour passed before he slowly opened his eyes. The fragments of the jade slip in his hand fell to the ground, and Chu Mu's eyebrows seemed to have a bit of strange color.

He thought for a moment, then sat on the ground, once again immersed in the Nine Dragons Divine Fire Formation in his mind.

This time, it took nearly three days before he opened his eyes again.

"Is this really possible?"

Chu Mu's eyes brightened slightly and he murmured to himself.

The formation is called Nine Dragons Divine Fire.

It is a... large formation that integrates offense and defense.

According to the description of the formation, this formation must use the spiritual fire of heaven and earth, the fire energy of earth veins, and such fire-attribute existence as its core source.

This formation layout evolved into nine fire-attribute dragons, integrating offense and defense. When foreign objects enter the formation, the Nine Dragons Divine Fire, even the powerful Nascent Soul, is difficult to resist.

If this formation is used in the cracks in that space, it will undoubtedly complement each other.

He did not destroy the earth veins in the space crack, and the demonic erosion was temporarily isolated by the unknown force.

If this formation is set up again, with the earth vein fire energy as the core, its effect will not be weaker than the original demon-sealing formation.

If this formation is blessed by the power of the secret realm of heaven and earth, even if the real demon comes personally with the blessing of the power of the demon realm of heaven and earth, he may not be able to escape the fate of being suppressed by this formation.

However, although the formation is extremely mysterious and magical, it can only be used to place the cracks in the space to suppress the erosion of the demon world.

He is just the organizer and has nothing to do with him.

But this formation seemed to... also bring him a little inspiration, or in other words, an inspiration, a brand new idea...

Chu Mu played with the jade slip in his hand, frowning, thinking silently.

The demonic erosion originating from the demon lord's remnant soul was obviously impossible to solve in a short period of time with his own power.

If it takes a long time, he is confident that the hidden danger of demonic erosion will be solved.

But obviously, such demonic erosion will not give him this time.

In this way, according to his decision, he would naturally use two rare spiritual objects, the blazing sun fire essence and the hibiscus wood, to refine the magic weapon that seals demons, to fight against the demonic erosion in the body and start a protracted war!

Naturally, he didn't have much idea about such a life-long treasure that broke his plan in such a hurry.

I ventured to this inheritance place because I wanted to take advantage of the illusory world to "refining falsehood into reality" and ponder and study it.

And now, take a look at this great formation.

Nine Dragons Divine Fire, integrated offense and defense...

It seems that he has a vague idea about this natal treasure.

He does not necessarily have to die in the direction of sealing demons and refining demons. He can completely seal demons like this Nine Dragons Divine Fire Formation, and it does not necessarily have to be aimed at demons.

Whether it is a demon or a monster, once it enters this formation, those who should be suppressed and refined by the Nine Dragons Divine Fire will be suppressed and refined, and the result is the same.

The Demon Sealing Formation can suppress the demon path, and this type of Nine Dragons Divine Fire Formation, which is not specifically used to seal demons, can also suppress the demon path.

Moreover, magic weapons do not necessarily have to be pure magic weapons...

If Chu Mu remembers correctly, in Jingmen City, the city defense formation that resisted the longevity sect's offensive for many years and even blocked the sword-wielding Yuanying in the end, the core of its formation disk was the life magic weapon of a Yuanying power.

The magic weapon is combined with the formation disk, and his life magic weapon can also be designed along this line of thought, with a little reference.

He is not short of offensive means.

The sword-wielding attack is unparalleled, and so is his sword intent!

What he lacks is defensive means.

As for defense, what existence can match the defensive ability of a defensive formation of the same grade?

He wanted to use the Great Sun Fire contained in the Fiery Sun Fire Essence and the Fusang Wood to resist and suppress the demonic erosion.

But relying on the Great Sun Fire contained in the two spiritual objects, the Fiery Sun Fire Essence and the Fusang Wood, it is difficult to completely eliminate the demonic erosion.

Therefore, he thought of refining it into a life-long magic weapon, so as to achieve the effect of one plus one greater than two, and thus, it can also achieve the result of resisting, or even suppressing and eliminating the demonic erosion.

The life-long magic weapon is one plus one greater than two.

What if the life-long magic weapon is combined with the formation?

That must be one plus one, far greater than two!

Suppressing the demonic erosion must be even easier!

Moreover, the Nine Dragons Divine Fire Formation in front of him seems to be quite in line with his fire attribute immortal cultivation.

He can completely learn from this Nine Dragons Divine Fire Formation, with his Great Sun True Fire as the core, Fusang Wood and Fiery Sun Fire Essence as the main materials, and conceive and design a life-long magic weapon that is completely in line with his own Great Sun True Sutra!

"The combination of the natal magic weapon and the formation... a square inch formation, which can attack, defend, suppress and refine..."

One idea after another emerged in his mind almost in an instant.

Chu Mu was a little unsure whether this idea was feasible.

But judging from his weapon refining skills, this direction must be feasible.

But judging from his formation foundation of just entering the second level, he was a little unsure.

If it were in the past, he might not have a good solution for this uncertainty.

But now, this problem does not seem to need to be considered too much.

Chu Mu looked at the towering Tianhen crystal stone on the high platform. The flickering faint fluorescence seemed to outline one illusory world after another.

A year is very short.

But for him, it is definitely enough...

...
