Longevity starts with learning

In the room, Chu Mu sat cross-legged.

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

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

From the time he obtained the puppet technique jade slip, to the underground auction house that day, to this book of refining notes, and then to the present.

Many years have passed.

The past seemed to be still vivid, and there seemed to be a little more complexity between his eyebrows.

After a while, Chu Mu calmed down a little, calmed his mind, and as his consciousness flowed, a fist-sized spiritual ore was suspended above the spiritual fire in an instant.

A bottle of spiritual oil was poured, and the spiritual fire suddenly rose. The scorching temperature was difficult to isolate from the one who controlled it with the fire control technique.

Under the burning of such a blazing spiritual fire, the spiritual ore 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.

The same is true for refining tools.

Each spiritual ore is a natural alloy with different properties.

The reactions produced by the combination and the final products are also different.

This is the most basic step and the most critical step.

What to keep and what to discard...

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

Chu Mu is very skilled, and it is smoother than he expected.

Under the "spiritual light blessing", the confidence in alchemy seems to appear in this tool refining.

However, tool refining is much more complicated than alchemy.

The knowledge system is also much larger.

After this step of alchemy, there is the hope of making a pill.

And after this step of refining tools, there are also the extremely complex tool patterns and array prohibition engravings.

Any slight mistake will result in all the previous efforts being wasted...

Fail once.

Fail twice.

Fail three times.

Fail five times.

Seven failures.

Ten failures.

In the end, he failed ten times for an ordinary low-grade magic weapon, and spent hundreds of spirit stones before he succeeded once.

With a cold and cold front hanging in front of him, Chu Mu was not happy at all after ten failures, but frowned.

The reason for the failure was very simple.

He did not fail once in the step of fusion of mineral materials.

All the ten failures were due to the engraving of the weapon pattern and the formation ban.

There was only one reason, that is, he was not familiar with it!

"Maybe, I got the wrong direction?"

Chu Mu sorted it out carefully, a little unsure.

After all, he had some inheritance of teaching by words and deeds in alchemy.

As for refining weapons, he was really a pure wild way.

He learned it completely by himself, without any teaching.

That refining notes was just reading from the book, without too many details.

As his thoughts flowed, Chu Mu looked at the spiritual ore beside him. While picking and choosing, a piece of fiery red spiritual ore floated on the spiritual fire.

In a moment, the blazing spiritual fire melted the spiritual ore!

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

In just a moment, a ball of red metal liquid floated in his hand.

As his spiritual consciousness flowed, the metal liquid turned into a round object.

Chu Mu pondered for a moment,

and added other spiritual materials. One after another, the patterns were formed on this ball of metal liquid with the manipulation of spiritual consciousness.

The patterns were very simple, with only a few patterns, wrapping this round fiery red.

The formation ban that was formed afterwards was also very simple.

There was only a basic formation ban.

Finally, the metal solidified, and a wave of spiritual energy suddenly emerged.

As the spiritual energy was absorbed and filled, the patterns on the metal ball also flickered faintly.

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

The metal oval was surrounded by several patterns, and the array was hidden deep in the center of the metal ball.

At first glance, the appearance of this metal ball was not exactly the same as the grenade in the previous life, but it was completely the same.

And its function was exactly the same as that of the grenade.

It was cast with the first-grade low-grade fire stone as the main body. While retaining the violent flame characteristics of the fire stone, a simple energy-gathering array was engraved.

The array gathered energy. As long as the energy-gathering array was detonated, the weak spiritual energy gathered would directly detonate the fire attribute spiritual energy retained in the fire stone like the firing powder of a grenade.

The principle was very simple and crudely made. It could not even be called a magic weapon. It could only be said to be a small refining gadget.

As for the power...

Chu Mu's mind moved, and with a roar, the little thing suspended in his palm turned into a ball of fire.

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

The next second, Chu Mu clenched his palm, the fire went out, and a ball of red and hot metal residue fell into his hand.

"It's probably equivalent to... a full-strength attack at the peak of secular Qi and blood?"

Chu Mu raised his eyebrows, and there seemed to be some difference.

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

When he was at the peak of Qi and blood, he could easily crush a boulder the size of a manhole cover with a full-strength attack!

It's crushing, not smashing!

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

Chu Mu was a little speechless. He didn't care about this gadget. This gadget could hardly harm any immortal cultivator.

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

Judging from the gadget just now, he is obviously a little empiricist, thinking that refining weapons is like refining elixirs, and must start directly.

But the facts prove that this is not the case.

The weapon pattern array is complicated, so he can practice it slowly first. Just like this gadget, with a few weapon patterns and one array, he can create a finished product.

It's just a piece of first-grade low-grade mineral material.

It's good for him, he has no experience at all and just goes straight to the finished product for refining...

Ten spiritual materials were wasted!

The spiritual materials require hundreds of times of energy. If the refining is successful, ten low-grade magic weapons will cost thousands of times!

"stupid!"

Cursing secretly, Chu Mu felt even more depressed, especially when he saw the accumulated metal residue.

That’s several thousand spirits!

What can't you do?

After a while, Chu Mu regained his composure. This time, Chu Mu did not rush to refine the Changhong Sword. Instead, he combined the mineral formations and pondered some gadgets while also familiarizing himself with the weapon pattern formations. .

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

Basically, they were conceived and designed in previous lives, and then refined using the art of refining weapons.

Ordinary grenades were used by him.

There are ordinary psychic blast attacks, there are also attacks using explosive metal fragments, and there are even pure array-forbidden attacks...

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

When it fails, it's an explosion.

Fortunately, they were all small gadgets with low technical content and their power could not cause any harm to him.

Even if this is the case, it is inevitable that he will be disgraced. There are metal residues all over the ground, and the area within the restricted area is a mess.

There was even a time when he experimented with something a little more complicated, using several formations connected to prepare for a more powerful thing.

But in the end, if he hadn't reacted in time, the micro-partition ban and the house would probably have been torn down.

Even so, Chu Mu could not hide his excitement. The depression of the previous ten failures had long disappeared.

Compared to refining the Changhong Sword by following the gourd's pattern, this feeling of thinking, designing, and refining by yourself is simply not that exciting!

Even after more than ten days of work, these gadgets are just useless in this world of immortality.

But the finished products of these gadgets undoubtedly prove that his ideas are not wrong.

It's useless now, it's just because his weapon refining skills are not enough!

In the future, as you accumulate experience in refining weapons and expand your knowledge, you can turn useless things into useful ones!

Unable to hide his excitement, he casually put away the pile of gadgets and prepared the spiritual materials for refining the Changhong Sword.

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

This time the refining, under the "spiritual blessing", was smooth and flowing from beginning to end.

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

Staring at the Changhong Sword in front of him, it seemed to be the sequelae of the previous ten days of tossing. At this moment, although he was still a novice at weapon refining, he couldn't help but point at the structure of the Changhong Sword.

What will happen if this formation ban is changed, what will happen if another formation ban is added, what will happen if the direction of this weapon pattern is changed, what will happen if that weapon pattern is removed...

I have so many ideas that I can’t help but want to put them into practice.

But seeing that there was not much spiritual material left, Chu Mu still suppressed this thought forcibly.

If we really go to the trouble, all these spiritual materials will probably be wasted!

His plan was disrupted.

Practice is a must, but don’t rush it. Once you earn enough spiritual stones, there will be plenty of opportunities.

After adjusting the breath for about half an hour, the spiritual fire was ignited, and another refining process began.

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

A shaped Changhong Sword was included in the storage talisman.

The spiritual materials accumulated in the room are also being refined in this way, and are being consumed visibly with the naked eye...
