Longevity starts with learning

The years passed in a flash.

In the retreat room, the blazing red had already infected the entire room, and pieces of spiritual paper with various experimental instruments written on them were scattered all over the floor.

The almost lifelike blades flickered on each piece of spiritual paper, and under the illumination of this red fire, they were even more real.

The true fire was blazing, and the color seemed to be as crystal clear as amber. As Chu Mu cast one spell after another, the red true fire became hotter and hotter. Under this blazing true fire, the nearly pure Nine Heavens Mysterious Gold twisted and changed rapidly, turning into a group of light golden liquid.

And this was just the beginning.

He was not an orthodox sword meaning true cultivator, and he mainly practiced the immortal way. Naturally, it was impossible for him to cultivate a sword pill that was extremely compatible with the true meaning like an orthodox sword meaning true cultivator.

If it could not be absolutely compatible, the best compensation measure was to pursue the ultimate purity of the sword meaning treasure!

According to his final design, this sword treasure must be made of Nine Heavens Mysterious Gold. On the premise of retaining the effect of the Big and Small Ruyi, he specially designed a set of quenching methods that pursue the ultimate for the quenching of the Nine Heavens Mysterious Gold, and a set of treasure refining methods that can be said to be almost unprecedented in his cognition.

The quenching method is simple, that is, two-pronged approach, true fire smelting, removing impurities, and further smelting into the Xuanjin essence required for refining the Big and Small Ruyi treasures.

Then, he set up the sword quenching formation he conceived for this purpose, using his sword sharpness as the source, and with the help of the formation, amplifying the sword sharpness to the extreme.

Finally, he used this formation to preside over the sharpness of the sword to quench the Xuanjin essence for 9981 days, completely eliminating any possible impurities, and at the same time, it also allowed the nature of the Nine Heavens Mysterious Gold essence, every strand, to be branded with his sword sharpness.

This makes the spiritual material itself extremely pure and sharp. Most importantly, this step is also the initial refining of this treasure. The 9981 days of quenching is equivalent to refining the prototype of the sword treasure.

Finally, with the essence of the black gold after repeated quenching, the prototype of the sword treasure, the special treasure refining method is used to refine the final life sword magic weapon.

Although such a process is cumbersome, there is no doubt that after this cumbersome process, this life magic weapon can also achieve a relatively perfect fit with him to the greatest extent.

Being able to do this, no matter how cumbersome or difficult it is, it is obviously insignificant to him.

Under the "spiritual light blessing", Chu Mu's expression is calm, and the quenching method or the treasure refining method have been verified by him countless times. If the data is judged, the probability of abnormality must be infinitely close to zero.

As his consciousness flowed, a series of spells fell. Following the process of his countless experiments and demonstrations, the essence of the spiritual materials smelted from the nine-day black gold also evolved accordingly.

Pure, pure, and pure again!

Until the end, with the fall of the quenching array, the red-flashing room and the criss-crossing array veins suddenly emerged.

Several groups of golden liquid that had turned into the essence of pure spiritual materials were suspended in the center of the array under Chu Mu's control and traction. The layers of array prohibitions lingered, pulling these groups of golden liquids from all directions to merge.

Chu Mu sat cross-legged, and the soul blade of the sea of ​​consciousness moved, and the criss-crossing knife lights, at this moment, also rose up in the array almost brilliantly.

Each gleam of knife light was shining, and it was crisscrossing around the several groups of gradually merging golden liquids. Every time the knife light passed through the several groups of gradually merging golden liquids, the properties of the group of golden liquids seemed to change and blend with it.

This process was just as Chu Mu had imagined, ninety-nine and eighty-one days, not a moment more, not a moment less.

At the last moment, the dazzling knife light disappeared without a trace in an instant, just as abruptly as it came.

In the center of the magic circle, several groups of golden liquids had completely merged into one, and only the fist-sized golden liquid ball was blooming with dazzling and eye-catching golden light.

The golden light was pure, just like the sun in the sky, and it was a little overwhelmed by the red light that illuminated the entire room. The golden and red intertwined, which was very beautiful.

Chu Mu felt relieved, but he was obviously exhausted. He closed his eyes and adjusted his breath for a long time, and when his spirit and energy returned to normal, he looked at the "sun" floating in front of him again.

The essence of spiritual materials is extremely pure.

After smelting for 9981 days, this ball of black gold essence, in a sense, is also close to transformation, and it is a transformation of "quality".

Nine Heavens Black Gold is a golden treasure with strong and killing power. It is hard and hard, killing everything, and it is unparalleled with the attack of the true meaning. It is undoubtedly very compatible.

But obviously, even if it is more compatible, it is still just an external object, and it is impossible to achieve the absolute and extreme fit of the sword pill and the knife pill.

Therefore, in order to further fit, the 9981 days of smelting he used was not just a simple smelting method, but to a greater extent, it borrowed the method of condensing the pill of the true cultivation of the sword.

Just like he condensed the golden pill, the heavenly thunder tempered the golden pill, and according to his understanding, the true cultivation of the sword intention is to temper the essence of the sword intention, and refine a knife pill that entrusts life.

After this smelting, in a sense, this ball of black gold spiritual material essence is equivalent to the prototype of an artificial knife ball.

And the final refining that follows, according to his repeatedly demonstrated ideas and concepts, is also completely different from the refining method of ordinary magic weapons.

The treasure of the sword does not need any engraving of array forbidden runes, nor does it need further artificial refining.

What is needed is to further perfect this "artificial sword ball prototype".

Chu Mu raised his right hand, and in the dark, this group of surging dazzling golden liquid was like an extension of his arm, under his control.

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

The sword is three feet long, with a slightly curved arc, the blade is light gold, and the blade is as cold as moonlight.

Apart from this, there is nothing special about it.

It is ordinary, not much different from the secular iron-cast sword.

After a brief look, Chu Mu rolled up his sleeves, and the blade softened. In the blink of an eye, it returned to the shape of metal liquid again, hanging in the palm of his hand. As his mind moved slightly, this group of golden liquid sank into the center of his eyebrows and seeped into his head.

At this moment, as this group of "knife ball prototype" sank into the sea of ​​consciousness, the soul blade in the sea of ​​consciousness seemed to have been stained with mottled gold.

In Chu Mu's perception, he could also clearly perceive that the knife ball prototype he had smelted had already intertwined and merged with this soul person between the boundary of reality and illusion.

The entire sea of ​​consciousness, at this moment, was like a pill furnace.

The crisscrossing knife intent was sharp, just like the heavy thunder that fell from the sky when he formed the pill.

And this group of black gold essence that had become the prototype of the knife ball was equivalent to a... prototype of the golden pill.

After carefully perceiving for a long time, Chu Mu slowly opened his eyes. He pondered for a while, moved his eyes, and finally fixed on a piece of spiritual paper not far in front of him.

That is... the final version of this knife intent treasure.

According to his argument, it will also take 9981 days for this treasure of sword intent to be completely shaped from liquid and invisible into a blade.

And this is just a new beginning.

Just like the nurturing of the natal magic weapon, this sword can also be nurtured in the sea of ​​consciousness with the big and small Ruyi. The sea of ​​consciousness is the elixir furnace, which is refined day and night, making this treasure more pure and more perfect with the sword intent.

In a sense, this treasure can be regarded as a natal magic weapon, and it can also be said to be a "sword pill" made by a person for the true cultivation of sword intent!

But strictly speaking, this treasure is quite different from both.

It can be said that it is an extremely special treasure that takes the strengths and essences of both.

Chu Mu is not sure whether there has been such a precedent in the world of cultivating immortals, but there is no doubt that all of this is derived from his own ideas, and there is no similar special case for him to refer to.

Therefore, this treasure, unlike his Nine Dragon Prison Tower or other cultivators' natal magic treasures, does not have a clear growth path.

Whether it is now or in the future, this special sword treasure will definitely require him to conceive and deduce it.

"The Changsheng Sect... maybe I should go there..."

Chu Mu murmured to himself, thinking.

The existence of "Linghui" is destined to make him different from all other immortal cultivators.

For example, if ordinary cultivators want to have a puppet or a magic weapon, they basically look for the corresponding instrument recipe first, then look for and collect the spiritual materials needed for refining, and finally find a reliable refiner to refine it.

If there are reliable connections, they can also find a refiner to customize it, and then according to the requirements given by the refiner, collect the corresponding spiritual materials for refining.

Just like his existence, the reason why the alchemy and weapon are so famous and respected is that everyone is willing to give him some face.

The fundamental reason is also here.

Whether it is elixir or implement, as long as it can provide enough benefits, even if it is tailor-made, he can do it.

And he himself, whether it is refining implements or refining elixirs, has never copied others. Even if it is Wangcai, the elixir he takes is tailor-made by him, matching his bloodline and his current cultivation.

For him, everything is perfectly matched to himself.

It is precisely because of this that he can step by step reach the present with his inferior qualifications.

After all, in this world of cultivating immortals, any elixir, any implement, and even any technique or method must have been improved or created by the predecessors.

The most suitable one must be the creator.

It is basically impossible for later generations to use and practice it to achieve 100% perfect results.

This is true for elixirs, magic tools, and magic treasures, as well as techniques and methods.

And he borrowed the "spiritual brilliance" to achieve the heaven-defying effect. No matter which aspect, he basically took the essence and discarded the dross.

From the beginning of learning, to in-depth study, to imitation, and finally to improvement, improvement, and improvement, until it is completely used for one's own use and reaches the ultimate perfection.

And this is obviously the difference between him and any other cultivator.

In the world of immortal cultivation, no cultivator, even a genius, can take care of too many unimportant things.

First, it is unnecessary, just like the sword dao Yuanying, like Xu Changqing, except for his own sword, he did not practice anything else.

Second, it is unlikely to have such talent, time and energy, and sufficient resources.

And Chu Mu, with "Linghui" by his side, is obviously not in this category.

His immortal cultivation can perhaps be summarized in one sentence.

That is... knowledge is power.

Since his spiritual roots are of poor quality, he can conceive and research elixirs that perfectly match his own practice, and even peek into the mysteries of spiritual roots, trying to research a way to change his fate.

He needs enough means to protect the way, so he tailors his own magic weapons and tools, and even ponders the bloodline supernatural powers, trying to use all the methods for his own benefit.

He lacks enough resources, so knowledge can be transformed into wealth. The title of "Master Chu" means a huge source of wealth!

And what is needed is obviously not just a knowledge system in a certain aspect, but an extremely large knowledge system.

The deeper and larger the knowledge he accumulates, there is no doubt that his immortal practice will be smoother and more stable.

And now he does not lack the knowledge system of corresponding skills, but a more comprehensive and broader cognition.

And this point, relying on himself alone, is obviously difficult to make up for this defect.

After all, what he needed was a vast sea of ​​knowledge like the Changsheng Sect's Sutra Library and the Xiandao Sect's inheritance site.

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

Chu Mu's eyes moved slightly, and the spiritual light slowly dissipated. With a flick of his sleeve, the piled-up manuscripts in the room were rolled up and neatly stacked in front of him. With a thought, the piled-up manuscripts fell into the storage space and were sealed.

Then, the projection appeared, and the blue bird puppet monitored the flickering shadows in all directions. After checking, when the projection dissipated, the flickering red light in the retreat room finally dimmed.

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

Bang, bang, bang...

A few crisp and dull roars, in a corner of the room, under the effect of the array, several high-quality fire attribute spirit stones were broken one after another, and the rich and pure fire attribute spiritual energy suddenly burst out and surged in the room.

The divine consciousness flowed, the fire attribute spiritual energy gathered, and a green robe moved with the gathering of spiritual energy. A pill entered the stomach, and a faint fluctuation of mana also appeared.

The seabed is dark, and it is difficult to distinguish between day and night. The flying boat is hidden in the void, motionless, and it is even more difficult to detect the changes in time.

Spring goes and autumn comes, year after year, in this quiet and dark seabed, it passes silently...
