Spring and autumn are fleeting.

In the retreat room, the scorching crimson had already infected the entire ashram, and pieces of spiritual paper with inscriptions depicting various experimental instruments were scattered all over the ground.

Near-lifelike blades flickered on each piece of spirit paper, adding a bit of reality to the light of this red fire.

The real fire was blazing, the color was as crystal clear as amber, and as Chu Mu's magic tricks fell, the crimson true fire became hotter and hotter, and one by one the almost pure Nine Heavens Xuanjin, under this blazing true fire, quickly twisted and changed, turning into a cloud of pale golden liquid.

And that's just the beginning.

He is not an orthodox sword intent true cultivator, he mainly focuses on immortal path cultivation, so naturally it is impossible for him to cultivate an existence that is extremely in line with true intent like the orthodox sword intent true cultivator.

If you can't achieve an absolute fit, the best remedy is to pursue the ultimate purity of the sword intent!

According to the concept plan he finally set, this sword intent treasure must be made of the Nine Heavens Xuanjin, on the premise of retaining the effect of the size of the wish, for the refining of the Nine Heavens Xuanjin, he specially conceived a set of refining methods for the pursuit of the ultimate, and a set of refining methods that can be called in his cognition, almost unprecedented.

The method of quenching is simple, that is, a two-pronged approach, smelting with real fire, removing impurities, and then further smelting into the Xuanjin essence needed to refine the size of the wishful treasure.

Then, he set up the sword intent refining array he conceived for this purpose, using his sword intent sharpness as the source, and with the help of the power of the formation, the sharpness of the sword intent was increased to the extreme.

In the end, he used this array to preside over the sharp sharpness of the sword intent to refine the Xuanjin essence for 9981 days, completely annihilating and removing any possible impurities, and at the same time, it was also to make the nature of the Nine Heavens Xuanjin Essence, every wisp of it, imprint the sharpness of his sword intent.

The most important thing is that this step can be regarded as the preliminary refining of this treasure, and the tempering of nine hundred and eighty-one days is equivalent to refining the prototype of the sword intent.

In the end, with this heavily tempered Xuanjin essence, the prototype of the sword intent treasure, with that special set of treasure refining methods, the final natal sword intent magic weapon was refined.

Although such a process is cumbersome, there is no doubt that after this cumbersomeness, this natal magic weapon can also reach a relatively perfect fit with him.

To be able to do this, no matter how tedious and difficult, for him, it is obviously a little insignificant.

Under the "blessing of spiritual light", Chu Mu's expression was calm, there were no waves in the ancient well, whether it was the method of refining or refining the treasure, it had been demonstrated by his countless experiments, if judged by data, the probability of abnormality must be infinitely close to zero.

The divine consciousness flowed, and one after another magic tricks fell, and according to the process of his countless experiments and demonstrations, the spiritual essence smelted by these several Nine Heavens Xuanjin also evolved with it.

Pure, pure, pure!

Until the end, as the refining circle fell, the crimson flickering room, and the criss-crossing forbidden veins, also suddenly emerged.

The several clusters of golden liquid, which had already turned into pure spiritual material essence, were suspended in the center of the magic circle under the manipulation and traction of Chu Mu, and the heavy array was confined, dragging these several clusters of golden liquid in all directions.

Chu Mu sat cross-legged, the blade of the Divine Soul of the Sea Consciousness moved, and the criss-crossing sword light rose up in the magic circle at this moment.

Every time the sword light passed through the gradually fused golden liquid, the nature of the golden liquid seemed to change and blend with it.

This process, just like Chu Mu envisioned, ninety-nine eighty-one days, not a single moment, a few moments, a lot of moments.

At the last moment, the brilliant sword light was as abrupt as it came, and it disappeared without a trace in an instant.

In the center of the circle, several clusters of golden liquid had completely fused into one, only the fist-sized ball of golden liquid bloomed with dazzling and dazzling golden rays.

The golden mangs are pure, just like the sky of the big sun, and they actually overwhelm the crimson brilliance that reflects the entire room, and the gold and red are staggered, and they are beautiful.

Chu Mu was relieved, but it was obviously difficult to hide his exhaustion, he closed his eyes and breathed for a long time, and when his spirit returned to normal, he looked at the round of "Great Day" suspended in front of him again.

The essence of spiritual materials is the ultimate purity.

After smelting like this for nine hundred and eighty-one days, this mass of Xuanjin essence, in a sense, is also almost transformed, and it is also a "qualitative" transformation.

The Nine Heavens Xuanjin, a metallic treasure, has the power of being strong and killing, its nature is rigid and hard, killing all things, and the attack of true intention is unparalleled, which is undoubtedly very compatible.

But obviously, even if it fits again, it is only a foreign object after all, and it is impossible to achieve the absolute ultimate fit like the sword pill and the sword pill.

Therefore, in order to further fit, this ninety-ninety-eighty days of smelting, what he used was not just a simple smelting method, but to a greater extent, it was borrowed from the method of condensing pills of sword intent true cultivation.

Just as he condensed the golden pill, the heavenly thunder quenched the golden pill, and according to his understanding, the sword intent really cultivated into the pill, it was the sword intent that quenched the essence and spirit, and refined a sword pill that entrusts his life.

After this smelting, in a sense, this mass of Xuanjin spiritual material essence is equivalent to the prototype of an artificial knife pill.

And the final refining that followed, according to the conception and assumption of his many arguments, was completely different from the refining method of ordinary magic weapons.

The sword intent treasure does not need any inscription of the forbidden rune, nor does it need to be further refined artificially.

What is needed is to further develop this "prototype of artificial knife pills".

Chu Mu raised his right hand, and in the dark, this surging cloud of dazzling golden liquid, as if his arm was extended, was under control.

His mind moved slightly, and the brilliant golden light swirled around his body, and its form also distorted and changed, and finally turned into a long knife hanging in front of Chu Mu.

The knife is three feet long, the arc is slightly curved, the color of the blade is pale gold, and the blade is as cold as the moonlight.

Other than that, there's something special about it.

Ordinary and ordinary, there is not much difference from the worldly iron-forged sword.

After a little look, Chu Mu's sleeves rolled up, the blade softened, and in a blink of an eye, it returned to the shape of metal liquid, hanging in the palm of his hand, and with the slight movement of his heart, this golden liquid did not enter the center of his eyebrows, seeped into his skull and disappeared.

And at this moment, as this group of "knife pill prototypes" did not enter the sea of knowledge, the blade of the divine soul in the sea of knowledge seemed to be stained with mottled gold.

In Chu Mu's perception, he could also clearly perceive that the prototype of the sword pill he had smelted was already intertwined and fused with this divine soul person who was between the boundary between the virtual and the real.

The whole sea of knowledge, at this moment, is like a furnace.

The criss-crossing sword intent is sharp, just like the thunder that fell all over the sky when he was married.

And this mass of Xuanjin Essence, which has become the prototype of the knife pill, is equivalent to a ...... Jindan prototype.

After perceiving it for a long time, Chu Mu slowly opened his eyes, he groaned slightly, his gaze shifted, and finally it was a piece of spirit paper frozen not far in front of him.

Namely...... The final draft of this sword intent.

According to his argument, this cultivation and condensation also takes ninety-nine eighty-one days, and this sword intent is a treasure, and it will be completely shaped from a liquid formless to a blade.

And that's just the beginning.

Just like the cultivation of the natal magic weapon, this knife can also continue to be cultivated in the sea of knowledge by the size of Ruyi, and the sea of knowledge is a furnace, day and night, imperceptibly refined, so that this treasure is more and more pure, and the fit with the knife intent is more and more perfect.

In a sense, this treasure can be regarded as a natal magic weapon, and it can also be said to be a man-made "knife pill" of true cultivation of sword intent!

But strictly speaking, this treasure is quite different from these two.

It can be said that it is an extremely special treasure that has evolved from the strengths of the two and the essence of the two.

In the world of cultivating immortals, Chu Mu didn't know if there was such a precedent, but there was no doubt that all of this was from his own ideas, and there were no similar special cases for him to refer to.

Therefore, this treasure is not like his Kowloon Town Prison Tower, or the natal magic weapon of other monks, it has a clearly visible growth path.

Whether it is now or in the future, this special sword intent treasure will inevitably need him to conceive for it and deduce and demonstrate it.

"Immortal Sect......... Maybe it's time to take a trip......"

Chu Mu muttered to himself, thoughtful.

The existence of "Linghui" is doomed, he is different from all other immortal cultivators.

For example, magic weapons, ordinary monks, if they want to have a puppet or a magic weapon, they basically first find the corresponding instrument, then find the spiritual materials needed for refining, and finally find a reliable refiner for refining.

If you have a reliable connection, you can also find a refiner to customize, and then according to the requirements given by the refiner, collect the corresponding spiritual materials for refining.

Just like his existence, the reason why Danqi Shuangjue is famous and his status is respected, everyone is willing to give him a little thin face.

This is also the root cause of this.

Whether it is an elixir or an artifact, as long as it can give enough benefits, even if it is tailor-made, he can do it.

And he himself, whether it is refining weapons or alchemy, he has never relied on the gourd to draw a scoop for a long time, even if it is prosperous, the pills he takes are all tailor-made by him, in line with his bloodline, and in line with his current cultivation.

Himself, that's what fits perfectly into himself.

It is precisely because of this that he can come to this point step by step with inferior qualifications.

After all, in this immortal cultivation world, any elixir, any prescription, and even any technique or method must have been improved or created by the predecessors.

The most suitable must be the creator.

Latecomers use it and practice it, and it is basically impossible to achieve 100% perfect results.

This is true of the elixir, the magic weapon is like this, and the same is true of the magic and the law.

And he uses the effect of "Linghui" against the sky, no matter what it is, he basically takes its essence and removes its dross.

From the beginning, we must study deeply, then copy and imitate, and finally improve, improve, and improve, until we completely use it for our own use, and achieve the ultimate perfection.

And this is obviously what distinguishes him from any monk.

In the world of cultivating immortals, no monk, even if he is a genius, cannot take care of too much inconsequentiality.

First, it is unnecessary, just like that kendo primordial infant, such as Xu Changqing, except for his own kendo, he has not cultivated anything else.

The second is that it is unlikely that you will have such talent, time, energy, and resources.

And he, Chu Mu, has a "Linghui" body, which is obviously not in this category.

His immortal path cultivation may be summed up in one sentence.

That's ...... Knowledge is power.

His spiritual root qualifications are inferior, so he conceived and researched an elixir that perfectly fits his own cultivation, and even peeked into the mystery of the spiritual root, trying to study the method of changing his life against the sky.

He needs enough means to protect the Dao, so he tailors his own magic weapons, utensils, and even pondering bloodline supernatural powers, trying to turn ten thousand laws into his own use.

If he lacks enough resources, then knowledge can be transformed into wealth, and he is known as "Master Chu", that is, the wealth of the sky is rolling in!

And what is needed for these is obviously not just a certain aspect of the knowledge system, but an extremely large knowledge system.

The deeper and larger the knowledge he has accumulated, there is no doubt that the smoother and more stable his immortal path cultivation will be.

Nowadays, he does not lack a knowledge system corresponding to the skills, but only a more comprehensive and broader cognition.

And this, on his own, is obviously difficult to make up for this shortcoming.

After all, what he needed was a collection of knowledge like the Immortal Sect's Scripture Pavilion, the place where the Immortal Dao Sect was inherited, and the vast sea of smoke.

"When this trip to the ruins is over......"

Chu Mu's eyes moved slightly, the meaning of the spiritual light slowly dissipated, he wiped his sleeves, and the paper manuscripts piled up in the room were rolled up, neatly stacked and suspended in front of him, and as soon as his mind moved, the stacked paper manuscripts fell into the storage space and sealed.

Immediately, the projection appeared, and the blue bird puppet flickered in the photo of the Quartet, and after checking it, when the projection dissipated, in the retreat room, the flickering red light finally dimmed.

Only the fluorescent stone emitted a faint white fluorescence, illuminating this retreat room, and also reflecting Chu Mu, who was already sitting cross-legged and practicing in retreat again.

Bang bang bang......

A few crisp dull roars, in the corner of the room, under the effect of the formation ban, several high-grade fire attribute spirit stones were shattered one after another, and the rich and pure fire attribute spirit qi suddenly burst out in the room.

The divine consciousness flowed, the fire attribute aura converged, and a Tsing Yi robe moved with the convergence of the aura, and a pill entered the abdomen, and a faint mana fluctuation also appeared.

The bottom of the sea is dark, day and night are indistinguishable, the flying boat hides in the void, does not move at all, and it is difficult to detect the change of time.

Spring goes to autumn, year after year, in this quiet and dark seabed, silently passing......
