Chapter 424: Nether Mine, the Journey Finally Comes to an End

Yu Jianqiu looked at the materials on the ground. Although he was blindfolded and could not see his eyes, a meaningful smile appeared on the corner of his mouth.

"You have a rich life experience!" Yu Jianqiu said.

Xu Hei knew what he meant, but he just smiled awkwardly and said nothing.

This guy probably knew that the Immortal Building was stolen by Xu Hei, and the heavy oil could explain some deeper problems.

But Yu Jianqiu did not ask much, and said calmly: "Have you ever made a flying sword before?"

Xu Hei took out the Black Dragon Sword. The grade of this sword was too low and he had already eliminated it.

Yu Jianqiu picked up the Black Dragon Sword, looked at it, frowned, and thought about it.

"I will forge one for you, but the subsequent sacrifice and warming will still need to be done by you."

"Of course!" Xu Hei nodded.

There are many steps in sword making, the most complicated of which is forging, and the longest is sacrifice, which will accompany you for life.

Whether a flying sword can be spiritual and have a sword soul depends mainly on the subsequent sacrifice and refining by the sword master.

"Release your artistic conception first, let me see what sword is suitable for you." Yu Jianqiu said calmly.

"I can't release the artistic conception yet."

Xu Hei explained helplessly that his artistic conception would only appear during battles and could not be released at all on weekdays.

"Oh?" Yu Jianqiu was quite surprised and said, "Then use your magical power."

Xu Hei did it immediately and performed the Canglong Immortal Method to call the wind.

The breeze that could blow everything to death blew towards Yu Jianqiu, but after getting close to an inch, it disappeared out of thin air.

"Desolate artistic conception? No! Destruction artistic conception? No."

Yu Jianqiu frowned.

Then, Xu Hei performed the call for rain, and a sparse rain appeared in the sky, falling down, and also disappeared when it was above Yu Jianqiu's head.

Although it was just a casual demonstration, Xu Hei was already exhausted.

Compared with the precise attack of calling the wind, calling the rain has a larger range and is suitable for large-scale killing, but it also consumes a lot of energy.

Yu Jianqiu fell into a long silence.

He found a problem. He couldn't see through Xu Hei's artistic conception!

From the two magical powers displayed by Xu Hei, he actually felt a variety of different artistic conceptions, which is impossible for other people.

In Yu Jianqiu's experience, only one cultivator in ancient times had multiple artistic conceptions.

That person was a legendary figure in those days. He was usually not very prominent. He was mediocre before forming the infant. But once he broke through, he became famous. He killed the middle stage of the infant in one move and could tie with the late stage of the infant.

You know, that person had just broken through at that time!

This is what Yu Jianqiu saw in ancient books.

Later, that legend stopped at the infant stage forever until his life span was cut off. The reason why he was recorded was because of his unique artistic conception.

However, Yu Jianqiu could not be sure that Xu Hei was as he thought.

"Forget it, I will forge a new flying sword for you based on your last one."

Yu Jianqiu shook his head and sighed, then picked up the Black Dragon Sword.

"Thank you, senior." Xu Hei bowed quickly, then asked: "May I ask how long it will take?"

"When the sword is finished, I will ask Xiong Dabao to send it to you, the time is uncertain."

Yu Jianqiu glanced at the materials on the ground and said: "Also, take all these back!"

Xu Hei was stunned and said: "These materials are..."

"Do I need these rags to forge a sword?" Yu Jianqiu asked back.

"..."Xu Hei was speechless.

This is the material he collected with great difficulty, but it was called rags.

But the implication is that Yu Jianqiu has better materials?

Seeing this, Yu Jianqiu sneered, took out a jade slip, and threw it to Xu Hei.

"There is a sword formation recorded here. If you can't bear to part with these rags, you can use this method to cast 72 flying swords to form a sword formation, which can be regarded as making the best use of them."

Xu Hei was immediately delighted, put away the materials, and bowed: "Thank you, senior."

Xu Hei left with joy.

This trip not only asked Yu Jianqiu to help him get a sword, but also obtained a set of sword formation diagrams. Next, Xu Hei will be busy.

Xu Hei returned to the cave and probed into the jade slip with his consciousness.

The jade slip recorded an extremely profound sword formation, called "Star Sword Formation".

The sword formation has four levels, namely the twelve Yuanchen, the twenty-eight constellations, the thirty-six Tiangang, and the seventy-two earthly evils, and each level is stronger than the previous one.

At the end of the sword formation, there are four levels combined to form the fifth sword formation, which is the strongest form of the star sword formation.

However, the number of flying swords required is extremely exaggerated. Without the support of a strong consciousness, it is impossible to control so many swords.

"It's really troublesome." Xu He sighed in his heart.

…………

Outside the Penglai Sea, in a dark and deep seabed.

Here, there is no sunlight all year round, and it is always a monotonous dark blue. The sea water is as calm as a deep well, as if there is a hazy formation that isolates everything from the outside.

Here is the external industry of the Penglai Sea, the Netherworld Mine.

It is also the place guarded by the external elder, the Hydra.

The Hydra has lived for more than a thousand years, and his cultivation is unfathomable. It is said that he was in the late Nascent Soul stage five hundred years ago. He is the strongest among the external elders.

At that time, he was the leader of the Sea Snake lineage. Later, in order to guard the mine, he handed it over to Elder Jin. However, this is the top secret of the Penglai Sea, and no one generally knows it.

Suddenly, at the end of the darkness in the distance, a white light lit up, separating the sea water, as if something was approaching at a very fast speed.

When the other party approached, it was discovered that it was a black dog and a man with purple hair. The man could no longer run, and he simply grabbed the dog's legs and came closer.

"Run! Run! Let me see how you run!"

A gloomy roar came from the distance, like a mad beast, the voice was hysterical.

The Soul Refining Demon Lord had never been so aggrieved in his life.

In order to chase these two damned people, he chased them for a whole month, from the south to the north, and almost circled the East China Sea, but he couldn't catch up.

On the way, he encountered various traps, formations, and natural disasters. He had gone through several dangerous places like the Dragon Triangle and was already covered with wounds.

No one knew how he had survived this month!

In order to avoid being tricked, the Soul Refining Demon Lord became cautious, but when he avoided a trap, he unexpectedly discovered that it was not a trap at all, but just a cover to trick him into taking a detour.

And when he thought he had seen through the other party's tricks, what he encountered was often a real killing disaster!

All kinds of false and real, true and false, made the Soul Refining Demon Lord furious as never before, and his killing intent had reached the limit!

He had already sworn with his heart of Taoism that he would not be a demon if he did not kill these two people!

"Swoosh! Swoosh!"

Hei Huang and Hunter accelerated and rushed into the range of the Netherworld Mineral Vein.

"Hmph, what is waiting for me in front?"

The Soul Refining Demon Lord was accustomed to the tricks of these two people. He rushed in without saying a word. Whether they were playing tricks on him or not, he was fearless. His cultivation was his greatest reliance!

All the way to chase, in order to make up for the loss, he had swallowed five ghost babies in a row. How could he give up halfway? No matter how much he paid, he must let those two people die miserably!

The Netherworld Mine is the top secret of the Penglai Sea, and no one knows its location. Even the elders of the six major veins are not qualified to access it, which also means that the Sea God Cult is completely unaware of it.
