Hearing the voice, a smile appeared on Lu Yu's face.

He disappeared into the air in an instant, and then appeared in the thirteenth underground floor of the Imperial Demon Division.

Then, Lu Yu couldn't wait to take out the long-awaited divine sword from his storage space, and with a flash of brilliance, a sheathed long sword appeared in front of his eyes.

The sword is pitch black, and the scabbard is carved with very intricate and simple patterns.

The sword was not unsheathed, but Lu Yu felt an extremely sharp and very domineering sword intent from it.

He grasped the hilt of his sword steadily, and drew his sword with a 'chok' thud.

"Zheng!"

The next moment, a clear and distant sound of the sword sounded between heaven and earth.

For a moment, the sky above the Imperial Ghost Division suddenly surged, a dark cloud gathered in the sky, and in the wind howling, the scorching sun in the sky disappeared in an instant.

But in an instant, the heavens and the earth were dark.

The Oni Guardians around the Oniji Division who were about to leave were all stunned in place, looking up at the vision above the sky, their eyes full of surprise.

Not only that, but when they heard the clear sound of the sword, the spirits and ghosts in their bodies all trembled involuntarily, as if they had felt something extremely terrifying.

And Cao Qiuran, Fang Qiong and Yu Zhenzhen were very keenly aware that this breath came from under the Imperial Ghost Division.

The three of them appeared in the thirteenth underground floor in a flash.

As soon as they entered, they saw Lu Yu and the long sword in his hand that was completely pitch black, but faintly restrained in golden light.

The first time they saw this long sword, the three of them were stunned, the brilliance blooming on the sword body was as pure and clear as a hibiscus out of water, and the carvings on the hilt of the sword shimmered with a deep and restrained light like the running of stars.

The sword and the darkness blend naturally, as naturally and soothing as clear water flowing over a pond.

And that sword spine is like a sacred mountain with thousands of walls, lofty and majestic!

"It's ......"

Cao Qiuran just stared at this sword for a few seconds and then involuntarily looked away, because he felt a majesty that he had never seen before.

It's like a subject meeting an emperor.

The spirit ghost in his body was also frantically signaling him not to keep staring at the long sword, which was a blasphemous act.

Lu Yu held the long sword in his hand and said lightly:

"Yin Tianzi Sword!"

When the words fell, the long sword vibrate, and everyone only felt that it was dark in front of them, and their brains suddenly exploded.

"Poof! Poop! Poop! ”

A metallic crash rang in everyone's ears.

In a trance, the four of them saw a giant holding a giant axe in his hand and chopping a sacred mountain that was ten thousand feet high, this sacred mountain was dark red all over, as if it was one body, and the entire sacred mountain exuded a metallic luster.

As if he didn't know how to get tired, the giant slashed at the mountain with an axe after axe.

Until the whole mountain was split, and a piece of ore with a dark color but an enchanting halo was removed from the belly of the mountain.

"Is this a sword?"

Seeing the picture flashing in his mind, Lu Yu's heart suddenly gave birth to such a thought.

At this moment, the screen turned.

A strong man with a bare upper body, knotted muscles, and a beard appeared in front of Lu Yu's eyes, and this strong man was holding a very exaggerated hammer in his hand.

In front of him was a huge iron felt and a huge red-hot stove.

It was the dark ore that was being calcined in the furnace.

And what surprised Lu Yu and the others the most was that it was a huge fire dragon that added fire to the stove.

The aura on this fire dragon's body was not much stronger than that of the Red Dragonmaiden, but at this moment, it coiled over this huge furnace, spitting golden-red flames into the furnace while throwing a kind of wood emitting a turquoise aura into the furnace.

After the wood was thrown into the furnace, a five-colored spiritual fire suddenly burned in the furnace.

The dark ore gradually turned red under the calcination of the five-colored spiritual fire.

Seeing this change, the mighty man with his upper body naked and holding a giant hammer directly volleyed the ore from the furnace.

After the ore fell on the iron felt, the big man raised the sledgehammer in his hand high.

"Boom!"

"Smack!"

The moment the hammer was raised, a loud thunderclap sounded in the sky.

Immediately after, a thick golden lightning bolt swooped down from the sky like an angry dragon, and then landed on the strong man's sledgehammer.

"Phew!"

A sound like a morning bell rang between heaven and earth.

The sledgehammer slammed into the red-hot ore with the power of the golden thunder, but the ore did not move at all, not even the slightest change.

And the big man didn't seem to notice the state of the ore, but once again raised the sledgehammer in his hand.

For a moment, the golden thunder in the sky was as dense as rain.

The strong man is like an emotionless iron-striking machine, hammer after hammer falls.

Under his unremitting forging, the ore finally changed little by little, and finally turned into the shape of a sword.

Suddenly, the picture changes again.

I don't know how many years have passed, the long sword in the strong man's hand has finally taken shape, it is the sword of the Yin Tianzi that Lu Yu is holding in his hand at the moment, but there is still one last step in this sword that has not been completed.

That's – quenching!

The sword was once again thrown into the furnace, and the five-colored spirit flame burned brightly.

At this moment, a woman dressed in a feather coat with strange patterns painted on her face fell from the sky, holding in her hand an earthy yellow water tank, which she placed on the ground.

"Boom!"

The whole earth, mountains and rivers seemed to shake because of this.

The woman flew into the sky, and in her hand there was an extra fan woven of various feathers, and she waved it vigorously, and then shouted loudly in a very strange tone:

"The wind is coming!"

"The rain is coming!"

"Here comes the water!"

The moment the words fell, a strong wind rose between heaven and earth.

The black clouds quickly converged in the sky, and in an instant, it was as if the whole world was about to collapse.

"Smack!"

A raindrop the size of a bean fell from the sky.

The next moment, it was pouring rain, and the heavenly river poured back.

The whole heaven and earth are all white, and the earth is like a country!

At this moment, there was a 'boom' sound, and the torrents gathered in the rivers, and the rivers swelled violently, but these rivers like the roar of an angry dragon seemed to be controlled by an invisible hand.

Rushing in the direction of the furnace!

Seeing this great supernatural power as if it had changed the world, Cao Qiuran couldn't help but sigh with emotion:

"Lei Gong strikes iron, the red dragon holds the furnace, and Yu Niang sends water, how spectacular this is, what kind of divine sword is this casting!"
