In the room, Chu Mu sat cross-legged.

The same spiritual materials were laid out, and the spiritual fire in front of him was already burning.

Although it was the first time to refine, for this time, Chu Mu had obviously been preparing for a long time.

From the beginning of obtaining the puppet art jade slip, to the underground auction house on that day, he got this volume of refining codex, and then to the present.

It's been a long time coming.

The past seems to be vivid, and between the eyebrows, it seems to be a little more complicated.

After a while, Chu Mu calmed down a little, calmed down, and between the flow of his divine sense, a fist-sized spiritual ore was suspended above the spiritual fire in the blink of an eye.

A bottle of spiritual oil was poured, the spiritual fire rose suddenly, and the scorching temperature, which was manipulated by the fire control technique, was also difficult to isolate.

That piece of spiritual ore, under the burning of such a raging spiritual fire, melted visibly with the naked eye, and finally turned into a pool of flowing liquid, suspended in front of Chu Mu.

Chu Mu was neither sad nor happy, and continued to refine in an orderly manner.

Just like alchemy, the most important thing is the fusion of medicinal properties.

And the same is true for refining weapons.

Each kind of spiritual ore is a natural alloy, and its properties are also different.

The reaction between the collocations and the final product are also different.

This is the most basic step, and it is also the most critical step.

What to keep and what to discard......

The principle of this step is the same as that of alchemy, and the operation is naturally no different.

Chu Mu is very skilled, and he is unexpected.

Under the "blessing of spiritual light", the kind of self-confidence in alchemy seems to have also appeared on this refining weapon.

It's just that refining weapons, compared to alchemy, is much more complicated after all.

The body of knowledge, too, is much larger.

Alchemy, after this step, is the hope of becoming a pill.

And the refining weapon, after this step, there is also the incomparably complex instrument pattern, which is forbidden to be inscribed.

The slightest mistake is a waste of all the work......

One failure.

Two failures.

Three failures.

Five failures.

Seven failures.

Ten failures.

In the end, he failed ten times and spent hundreds of spirit stones to succeed once.

The cold cold front hung in front of him, and after ten failures, Chu Mu did not have the slightest joy, but frowned.

The reason for the failure is simple.

This step of mineral fusion has not failed once.

The ten failures are all due to the inscription of the instrument pattern and the forbidden formation.

There is only one reason for this, and that is that he is not familiar with it!

"Perhaps, misdirectional?"

Chu Mu combed it carefully, a little unsure.

After all, alchemy, he also has a little inheritance of words and deeds.

And the refiner, that ...... He's really a pure wild man.

Completely self-taught, without the slightest teaching.

The Refining Codex was only a script, and there were not many details at all.

Between the flow of thoughts, Chu Mu looked at the spiritual ore beside him, and between picking and choosing, a piece of spiritual ore with a fiery red color was suspended above the spiritual fire.

In a moment, the blazing spiritual fire melted this piece of spiritual ore!

This time, Chu Mu did not add any other spirit ore, but directly began to remove the impurities of this spirit ore.

In just a moment, a red mass of metallic liquid was suspended in his hand.

In the middle of the flow of consciousness, the liquid metal turned into a round object.

Chu Mu pondered for a moment,

The addition of other spiritual materials, one by one, with the manipulation of the divine consciousness, is also formed on this mass of metal liquid.

The texture of the vessel is very simple, with only a few lines, wrapping this round fiery red.

The formation of the forbidden formation was also extremely simple.

There is only one basic battle ban.

Eventually, the metal froze, and a wave of aura fluctuated.

As the aura was absorbed and filled, the patterns on the metal ball were also faintly flickering.

Chu Mu raised his hand, and the metal ball was suspended in his hand.

The metal oval is surrounded by several patterns on it, and the one that is forbidden is hidden deep in the center of the metal ball.

At a glance, the appearance of this metal ball is exactly the same as the grenade in the previous life, it can only be said that it is exactly the same.

And its effect is exactly the same as that of a grenade.

Cast by the first-order lower-grade Fire Flame Stone as the main body, while retaining the flame irritability characteristics of the Fire Flame Stone, a simple gathering array is inscribed.

As long as the Gathering Array is detonated, the faint psionic energy it gathers will directly detonate the fire attribute psionic energy retained in the Flame Stone like the firing charge of a grenade.

The principle is very simple, and it is also very shoddy, and it can't even be said to be a magic weapon, it can only be said that it is a refining gadget.

Words of might......

Chu Mu's heart moved, and with a roar, the gadget suspended in the palm of his hand turned into a ball of fire.

But in the end, this ball of fire, as well as the exploded metal fragments, seemed to be restricted by an invisible energy, like a ball of fire, still suspended in Chu Mu's palm.

In the next second, Chu Mu shook his palm, the fire was extinguished, and a cloud of metal residue that was still red and hot fell into his hand.

"Roughly equivalent to...... A full-strength blow to the peak of worldly qi and blood? ”

Chu Mu raised his eyebrows, as if there was a slight difference.

With such power, compared to the previous life, it is not a grenade!

When he was at the peak of his qi and blood, he struck with all his strength, and a boulder the size of a manhole cover could easily smash it!

Smash, not smash!

"So, it's really wrong......"

Chu Mu was a little speechless, he didn't care about this gadget, this gadget was hardly lethal to any immortal cultivator.

He was speechless that he had wasted ten spiritual materials in vain!

Judging from this gadget just now, he was obviously a little empiricist, thinking that refining tools and alchemy had to start directly.

But it turns out that this is not the case.

The instrument pattern array ban is complicated, he can practice it slowly first, just like this gadget, a few instrument patterns, a formation ban, you can make a finished product.

The left and right are just a piece of first-order low-grade mineral material.

It's good that he doesn't have any experience at all, so he goes directly to the finished product for refining......

Ten spiritual materials were wasted in vain!

Spiritual materials have to be hundreds of spirits, if the refining is successful, ten low-grade magic weapons, that is thousands of spirits!

"Stupid!"

Secretly scolded, especially when he saw the accumulation of metal residues, Chu Mu was even more depressed.

That's thousands of souls!

Why not?

After a while, Chu Mu cleaned up his mood a little, this time, Chu Mu was not in a hurry to refine the Changhong Sword, but combined with the mineral array forbidden, pondering some gadgets at the same time, he was also familiar with the weapon pattern array forbidden.

In the blink of an eye, more than ten days passed, and in front of Chu Mu, there were also a bunch of gadgets.

Basically, it was conceived and designed in the previous life, and then combined with alchemy.

An ordinary grenade, he played with a flower.

There are also ordinary attribute psionic explosion attacks, there are also attacks that use explosive metal fragments, and there are even pure forbidden attacks......

Of course, the array ban experiment combined with gadgets will inevitably fail, especially since he also focuses on such one-time attack gadgets.

A failure is an explosion.

The gains and losses are all gadgets, the technical content is not high, and the power cannot cause him harm.

Rao is like this, and it is rare to be disgraced, and the metal residues all over the ground are in a mess within the scope of the partition prohibition.

Even, on one occasion, his experiment was a little more complicated, using several array forbidden connections, ready to make a more powerful gadget.

But as a result, if he hadn't reacted in time, even the miniature partition ban, as well as this house, would have been lifted.

Despite this, Chu Mu still couldn't hide his excitement, and the depression of the previous ten failures was long gone.

Compared with the refining of the Changhong sword that draws a scoop according to the gourd, this feeling of pondering, designing, and refining by yourself is simply not too cool!

Even if it is tossed for more than ten days, these gadgets are just useless things in this immortal cultivation world.

But the finished products of these gadgets undoubtedly prove that his thinking is not wrong.

It's useless now, it's just that his alchemy background is not enough!

In the future, the experience of refining weapons will be accumulated, the knowledge will be broadened, and it will be useful if it is useless!

He couldn't hide his excitement, and casually put away this large pile of gadgets and prepared a spiritual material for refining the Changhong Sword.

The spiritual fire that had just been extinguished was lit again.

This time refining, under the "blessing of spiritual radiance", it is a flowing water from beginning to end.

About two hours later, a complete Changhong Sword was suspended in front of him.

Looking at the Changhong Sword in front of him, it seemed to be the sequelae left by the tossing of the previous ten days, at this moment, although he was still a refining Xiaobai, he still couldn't help but point out the structure of the Changhong Sword.

What will happen if this array ban is changed, what will happen if a formation ban is added, what will happen if the direction of this instrument pattern is changed, and what will happen if that instrument pattern is removed......

There are so many ideas that I can't help but want to put them into practice.

But seeing that there were not many spiritual materials left, Chu Mu still forcibly suppressed this thought.

If you really want to toss, then these spiritual materials, I'm afraid they will have to be wasted!

His plan was disrupted.

Practice is a must, but there is no rush for a while, if you earn enough spirit stones, then there will be many opportunities.

After about half an hour of pranayama, the spiritual fire was ignited, and another refining began.

And the next ten days will be more than ten days of flowing water.

A long-rainbow sword with a shaped handle is stored in the storage charm.

And the spiritual materials piled up in the room are also being refined in this way, and they are visibly consumed by the naked eye......
