Becoming a Taoist Master by Walking on the Underworld

Chapter 349 Refining the Natal Heart Sword, Yin-Yang True Fire Achieved

Chapter 345

The Yin-Yang True Fire at the Lesser Completion level has not only increased in power, but its flames are also significantly more powerful than before.

The time required to cast the spell was reduced from the original twenty-five breaths to only ten breaths.

Efficiency has been greatly improved.

Although ten breaths is not enough time to use it smoothly in battle, for him, the Yin-Yang True Fire at the minor completion level is enough for him to refine his own unique natal magic weapon.

Thinking of this, Chen Yushu had a sudden thought, and a large pile of materials appeared beside him.

Among them were Kunlun True Stone, Ten-Thousand-Year Blood Essence Stone, Star Meteorite Iron, Taiyi Silver Marrow, Thousand-Year Cold Crystal... Most of them were items he obtained from other cultivators' storage bags.

Of course, some of them he obtained from the lair of the true dragon.

Although the Azure Dragon was still in its juvenile stage, it was clear that an adult dragon had lived in that place before it, and thus stored many treasures.

Spirit stones are only a small part of it; the majority consists of various rare and hard-to-find materials.

During his rampant plundering, he collected almost all the spirit ores, so much so that he had no shortage of materials.

After taking out all these materials, Chen Yushu did not rush to use Yin-Yang True Fire to smelt them.

Instead, he reached out and flipped his hand, taking out a jade slip.

It was in the ancient cultivation cave that he obtained the jade slip containing the Heart Sword Technique.

The Heart Sword Technique is indeed a swordsmanship method, but what is truly special about it is its training method.

It is a natal magic weapon that is forged directly within the cultivator's body and grows little by little.

Therefore, any cultivator who wants to forge their own Heart Sword must master True Fire.

Among ancient cultivators, even the inner fire of those at the Core Formation stage is sometimes insufficient to truly forge the Heart Sword.

As for the Yang Fire of cultivators who have entered the Dao Day Travel Realm, in terms of intensity, it is not as good as the Dan Fire, so it is naturally inferior.

Fortunately, Chen Yushu mastered the true fire-type supernatural power, Yin Yang True Fire.

Even if it's just a magical version of Yin-Yang True Fire, once he cultivates it to the minor completion level, its power is stronger than Core Formation True Fire. It can already barely melt down magical treasures to form materials for the Heart Sword, and then draw in and absorb them to forge his natal Heart Sword.

Thinking of this, Chen Yushu took a deep breath and quickly unleashed the Yin-Yang True Fire.

One breath, two breaths, three breaths...

After ten breaths.

boom!
Yin and Yang True Fire took shape.

Without the slightest hesitation, he directly guided one of the materials, the Kunlun True Stone, into the Yin-Yang True Fire.

In an instant, the Kunlun True Stone was melted into a liquid state, and countless impurities and fragments were burned into ashes and separated from the material.

But just being liquid isn't enough.

To forge a natal sword, one must transform the essence of the materials into a finer and purer form than liquid.

Only by using the essence of materials can they naturally combine within a cultivator's body to transform into materials for the Heart Sword, forming the natal Heart Sword.

Fortunately, his Yin-Yang True Fire was powerful enough to refine anything. The liquid Kunlun True Stone only lasted a short time before it was quickly melted down again and transformed into the essence of Kunlun True Stone.

Then, with a thought, Chen Yushu, following the method of the Heart Sword Technique, guided the wisps of Kunlun True Stone essence into his body.

Once the essence of the true stone entered his body, it was enveloped by his Dao Yuan and remained suspended in his dantian.

It did not melt, but remained as its essence until he refined all the Kunlun True Stone solution into Kunlun True Stone Essence.

However, he did not stop at this point.

Instead, another material is taken out and processed in the same way, melted into the corresponding material essence, and then absorbed into the body.

This is a slow process that requires careful attention.

Only the finest materials are what he needs.

Any extra impurities will affect the quality of his natal magic weapon.

It's important to know that even though they are all considered natal magic weapons, there are actually differences.

The materials themselves are inherently different.

For example, Li Xin, the Grand Elder of the Seven Gods Sect, had his natal magic weapon crafted using the yang fire within his own body.

At most, one can only melt down the materials for magical artifacts and turn them into a liquid state. This liquid state contains many impurities and has not undergone further refinement to form the essence of the materials, so its toughness will be much worse.

While it is certainly far more powerful than the magical artifacts used by cultivators of the same realm, the difference will be quite obvious when encountering cultivators who possess top-tier magical artifacts or natal magical artifacts.

Especially cultivators like him who use the essence of materials to refine their natal magic weapons.

A single strike from a flying sword could shatter his natal magic weapon.

However, since it is a magical version of Yin Yang True Fire, although powerful, it is not long-lasting.

After he melted the third material into its essence, he ran out of energy and the melting speed decreased significantly.

Seeing this, Chen Yushu quickly dispelled the spell and then cast it again.

Fortunately, he was in the Netherworld at the time, where spiritual energy was abundant, and his recovery speed was very fast.

He quickly unleashed the second Yin-Yang True Fire and continued to smelt various materials.

Three, four, five...

Various materials are melted down into their essence, which is then drawn into his body.

They merged with each other, and then, depending on his thoughts, they transformed into various forms.

For example, the shape of a sword.

For example, knife-shaped, spear-shaped, stick-shaped, tripod-shaped, bell-shaped...

After careful consideration, Chen Yushu decided to solidify it into a sword shape.

After all, he has now obtained the Heart Sword Sect's inheritance and has the corresponding sword dao divine power in hand. He can also melt his natal magic weapon into the shape of a flying sword and thus better unleash the power of his sword dao divine power.

Therefore, after the essence of the materials had been almost completely melted down, Chen Yushu began to set up the restrictions of the Heart Sword Technique inheritance on the gradually taking shape flying sword.

This is actually a process that takes time. If someone knows nothing about array formations, it will take at least one or two months to fuse all the sword formation restrictions into the array.

Fortunately, Chen Yushu's mastery of array formations was also considerable; he could understand the true meaning of many restrictions with just a glance.

However, it took a full three days to completely melt the restrictions into it, laying a solid foundation for his natal magic weapon.

"My natal sword is finally complete!"

As Chen Yushu melted the last restriction into it.

Then a thought struck him.

Buzz~!

A nearly transparent flying sword swiftly shot out from his body.

This is the natal flying sword he forged.

Even though it hadn't been refined yet, the flying sword still exuded a strong sword aura, with faint sword light shooting out, cutting through the surrounding air and causing ripples to spread through it, which was quite astonishing.

"go with!"

Then, Chen Yushu waved his hand.

The flying sword immediately transformed into a streak of light, rushing directly to a giant rock in the distance.

It passed right through the boulder without making a sound.

"So strong?"

Moreover, with the sword energy contained within, there was almost no leakage, only retaining the minimum penetrating power... and most importantly, the speed of this flying sword.

too fast.

"A sword strike as swiftly as a startled swan; in battle, that's a huge advantage."

Seeing this, Chen Yushu was also somewhat alarmed.

It was clear that the power of his flying sword far surpassed that of the natal magic seal that Li Xin had previously used. Not only in power, but most importantly, in speed.

It flew out quickly according to his thoughts, without any hesitation whatsoever.

Even if others also possess their own natal magic weapon, they will still be a step slower than him in terms of speed.

This is the power of the Heart Sword Technique.

Regardless of power, the speed will be even faster.

Not to mention the natal heart sword forged through the refining method of the Heart Sword Technique, which is also extremely powerful.

In the same realm, few can rival it.

This is the fundamental reason why the Heart Sword Sect was so rampant in ancient times.

"With this flying sword, my methods will become much more diverse."

It also greatly improved my skills.

Facing Lin Xin again, I wouldn't need to use any of those spells; a single flying sword would be enough to easily kill him.

With these thoughts in mind, Chen Yushu sent the flying sword flying back at the same speed, surging into his body.

"However, this flying sword is only just taking shape at this moment."

Although it is already quite strong, this is not its limit.

I can still continuously melt various materials into it, constantly increasing its essence, making it heavier and stronger..."

Chen Yushu already knew.

There is no limit to the power enhancement of one's natal magic weapon.

Not only can the natal magic weapon be continuously refined and improved as the cultivator's own strength increases.

Its material is not determined by the grade of the material initially smelted.

It can grow.

It can continuously melt various rare materials, thereby increasing its strength and making it more resilient and powerful.

So Chen Yushu made his move again, using the Yin-Yang True Fire.

Then, with a thought, he took out a magical artifact.

This is the prototype of a magical artifact.

It was the natal magic weapon condensed by Zhou Hengyang, the fourth elder of the Seven Gods Sect.

It was only because of insufficient time and his insufficient true fire that, even though many rare materials were fused into the magic weapon, he could only refine this prototype magic weapon.

It cannot be used in combat yet.

However, even if it is only a prototype of a magical artifact, the value of its materials is real.

Chen Yushu naturally wouldn't waste it.

At this moment, he wanted to use the Yin-Yang True Fire to melt down this prototype of the magic weapon, turning it into pure material essence, and then integrate it into his natal sword.

Compared to ordinary materials, the refining process of this smelted magical artifact prototype is much slower.

Fortunately, Chen Yushu's Yin-Yang True Fire was quite powerful, capable of refining anything. After a dozen or so breaths, it gradually melted the magic weapon, slowly transforming it into a liquid metal.

After a hundred breaths, he finally refined the first batch of material essence.

Then came the second one, the third one...

Chen Yushu continuously extracted the essence of the materials and quickly integrated it into his natal magic weapon, constantly strengthening its origin.

It's a slow process.

Chen Yushu, however, kept going.

After the Yin-Yang True Fire dissipated, another Yin-Yang True Fire was summoned to continue the refining process.

Spell Version of Yin Yang True Fire: Minor Success (377/400)

Unbeknownst to him, after absorbing all the material essence from the embryonic form of that magical artifact, his cultivation of the Yin-Yang True Fire spell was also raised to the minor completion level (377/400), not far from the major completion level.

"When the Yin-Yang True Fire is fully mastered, its power will far surpass that of when it is only partially mastered."

Whether it's for smelting materials for magical artifacts or for refining pills, the effects are far superior to before.

Not to mention, once I reach mastery, I will be able to unleash Yin-Yang True Fire even faster, which may then be useful in combat.

It's like I've suddenly gained a powerful offensive supernatural ability..."

Upon seeing this, Chen Yushu's eyes lit up, and he immediately became somewhat excited.

He had originally planned to stop refining the magic weapon, but suddenly he was motivated to continue.

So, after he used his internal energy to recover the Dao Yuan he had previously consumed, he took out another magic weapon.

This magical artifact is the same natal magic seal used by Li Xin, the Grand Elder of the Seven Gods Sect.

He planned to incorporate the materials from this large seal into his natal sword to further enhance its power.

boom!
The Yin-Yang True Fire was unleashed.

The scorching heat instantly baked the magic weapon, and in a flash, it erased the spiritual imprint that originally belonged to Li Xin from the seal.

"This is quite an unexpected surprise."

In this way, if I obtain other cultivators' magical treasures in the future, I can also use the Yin-Yang True Fire to erase their spiritual imprints and refine and use their magical treasures in a short period of time.

Even if you don't need it yourself, giving it away or reselling it will make things much easier.

Chen Yushu raised an eyebrow, somewhat pleased, but without much emotional fluctuation.

Compared to the prototype of the natal magic weapon, this completed natal magic weapon is indeed far superior in terms of toughness.

Chen Yushu's Yin-Yang True Fire was still unable to completely melt it.

So Chen Yushu cast the spell again, unleashing a second Yin-Yang True Fire.

So back and forth.

It wasn't until after the third stage that the seal gradually showed signs of being smelted.

However, the speed was indeed much slower than when the prototype of the magic weapon was smelted before.

So Chen Yushu cast the spell again.

Buzz~!

suddenly.

Chen Yushu was startled, suddenly feeling countless cultivation experiences and insights about Yin-Yang True Fire surging into his mind.

It was as if he had practiced and performed this magical technique countless times in a short period of time.

"The Yin-Yang True Fire has been perfected!"

In an instant, Chen Yushu understood.

Having perfected his own version of Yin Yang True Fire, he continuously optimized and improved it as countless insights surged forth.

Then, he unleashed the Yin-Yang True Fire once again.

One breath, two breaths, three breaths...

It only took four breaths.

boom!
A fainter, yet purer, wisp of Yin-Yang True Fire then appeared.

Then, with a thought, he controlled his flying sword to rush to the bottom of that large seal.

sizzle...

In the blink of an eye, the seal was melted, forming a liquid metal shape. Then, in just two breaths, clusters of material essence took shape.

The speed is more than ten times faster than before.
