Dragon's Roar Slash

In fact, given Lin Mu's current cultivation level, it's still quite unrealistic for him to forge an SS-grade weapon.

However, he has the Black Saber King.

As the Blade Spirit of this weapon, Black Saber King can control the blade and make it melt faster.

For the Black Saber King, the tasks it had to accomplish were no less than those for Lin Mu.

Lin Mu walked into the Formation and placed the Six Source Demon-Slaying Saber on the ground.

His hands manipulated the Formation.

The flames moved within the Formation.

Flames landed on the Six Source Demon-Slaying Saber.

The long sword floated in mid-air.

The Phantom of the Black Saber King enveloped the longsword, its hands quickly clasped together, and streams of power fell upon the Six Source Demon-Slaying Saber.

The Six Source Demon-Slaying Saber trembled slightly, and its blade quickly turned red.

The Black Saber King had a pained expression on his face.

However, it is no ordinary Blade Spirit. Even in this state, it can remain clear-headed and continuously control the Six Source Demon-Slaying Saber to make it present its best condition.

Convenient for tempering.

Lin Mu quickly formed hand seals.

A large amount of flame gathered on the Six Source Demon-Slaying Saber, and some liquid appeared on the surface of the Demon Slaying Saber, indicating that the Demon Slaying Saber was melting.

This was only possible with the help of the Black Saber King; otherwise, it definitely wouldn't have been this easy.

Just then, Lin Mu took out the Hundred Refinements Profound Crystal Stone and placed it next to the Six Source Demon-Slaying Saber.

At this moment, the Black Saber King chanted Cursed Script.

Under the influence of the Cursed Script, the Six Source Demon-Slaying Saber seemed to undergo some kind of change, and actually began to actively devour the nearby Hundred Refinements Profound Crystal Stone.

This is a characteristic of all SS-grade weapons.

It has the ability to absorb high-grade materials.

However, bringing out these characteristics is not so easy.

The Black Saber King's face showed pain.

Despite enduring immense pain, it continued to form hand seals, gathering a large amount of power into the blade and forcing it to devour the mystic crystal.

Seeing this, Lin Mu continuously activated his Source Force to control the Formation and minimize the Black Saber King's pain as much as possible.

As time slowly passed, the luster on the Six Source Demon-Slaying Saber continued to increase, and the cracks healed accordingly.

It was as if a Fierce Beast was gradually awakening.

Black Saber King also reached his limit at this moment, and his consciousness became somewhat blurred.

Lin Mu's hands quickly formed hand seals. He knew very well that Black Saber King had only just recovered and that he had already reached his limit by the time he had lasted this long.

Lin Mu took a deep breath, and a large amount of Divine Soul Power surged into the Formation, at which moment the Divine Soul Eye opened.

He imitated the Black Saber King's method, continuously infusing the Six Source Demon-Slaying Saber with Divine Soul Power.

Because he was the owner of the Six Source Demon-Slaying Saber, the blade did not reject his Divine Soul.

Instead, it continues to absorb.

In this state, the Six Source Demon-Slaying Saber remains in its previous state.

The Hundred Refinements Profound Crystal Stone continued to shrink.

In just over ten minutes, the entire crystal was devoured by the Six Source Demon-Slaying Saber.

The Six Source Demon-Slaying Saber Blade trembled slightly.

It was as if they had eaten their fill.

Lin Mu breathed a sigh of relief and once again controlled the Formation to reduce the power of the flames, ensuring that the Six Source Demon-Slaying Saber was in optimal condition.

Black Saber King looked extremely weak, and his gaze toward Lin Mu held a hint of admiration.

When he could no longer hold on, Lin Mu intervened in time and used his Divine Soul Power to simulate his strength.

Such reaction speed and mastery of the Heaven-Seizing Art have reached the level of a veteran.

It would be impossible to achieve this without several years of hard work and dedication.

But Lin Mu only spent a little over twenty days.

Such talent is truly amazing.

"I wonder what level he can reach if I pass on the Nether Emperor's legacy to him?" Black Saber King thought to himself.

At this moment, the surrounding flames completely disappeared, and the Six Source Demon-Slaying Saber still floated in mid-air.

The patterns on the blade are extremely beautiful, as if six different attributes are converging.

Lin Mu waved his hand, and the Six Source Demon-Slaying Saber flew towards him.

It landed in the palm of his hand.

Holding the long sword, Lin Mu could clearly feel its sharpness.

Six different Attribute Power are transmitted from the blade.

It was like Fierce Beast that could breathe.

It's no exaggeration to say that this knife is at least several times better than before.

This will allow Lin Mu's combat power to be better brought into play.

"That's really impressive! This is an SS-grade weapon!" Lin Mu exclaimed.

"This is still an SS-grade weapon that hasn't been fully restored. Once it's fully restored, it will be even stronger!" Black Saber King explained.

"Furthermore, this knife is not simple; it should have its own special abilities!"

Lin Mu looked surprised.

Comes with its own special skills!

This is a very rare ability.

"What skill!"

"Try to infuse the blade with six different types of Divine Soul Power, and then use Source Force to activate it!" the Black Saber King explained.

Following the Black Saber King's instructions, Lin Mu poured streams of Divine Soul Power into the longsword.

All that could be seen were streaks of luster on the surface of the blade.

In the distance, it seemed as if a golden dragon was coiling around, emitting a series of Dragon's Roar.

The longsword trembled slightly, and an extremely powerful aura emanated from it.

There was a hint of disbelief in Lin Mu's eyes.

He knew very well that the aura emanating from this knife had reached the level of Fourth Tier Martial Artist.

In other words, when fully activated, it can unleash the combat power of Fourth Tier Martial Artist.

"Just a knife can have such power!" Lin Mu thought to himself.

He had only activated a small portion of the energy.

If it is activated at full power, it will definitely become stronger.

The Fourth Order he mentioned is the level that this sword can reach on its own.

And the power it unleashes will vary depending on the martial artist who wields it.

"What's this move called?" Lin Mu asked.

"Dragon's Roar Slash!" Black Saber King.

"Not bad!" Lin Mu said.

"It should still have some abilities left, which should be revealed as it recovers!" Black Saber King explained.

"Okay!" Lin Mu nodded.

Black Saber King hesitated for a moment before saying, "Lin Mu, I have some cultivation techniques here. I wonder if you would be willing to practice them?"

Lin Mu was slightly taken aback; he knew what the Black Saber King was talking about.

This should be a follow-up measure by the Nether Blade.

"What are the conditions?" Lin Mu asked.

"I need you to do three things for me!" Black Saber King said seriously.

"You say!"

"First, I hope you can kill the Demon beneath the academy," Black Saber King.

Lin Mu's face showed some hesitation.

He knew very well what level that Demon was, and that it would be very difficult for him to do so with his strength.

"If it doesn't die, many others will die in the future! With such a talent, you can't possibly escape unscathed!" the Black Saber King added.

Lin Mu nodded slightly.

"I'll give it a try! But I can't guarantee success!"

"If you're determined to do it, you can definitely succeed!!!"
