Ning Chen returned to the sect from the place where the bones were buried, and went straight to the Wanzang Pavilion, and used 10,000 sect contribution points to learn the method of refining the Natal Demon Sword.

Then he came to the Refining Hall and exchanged the remaining sect contribution points for the auxiliary materials for refining the Natal Demon Sword. After applying for a refining room from the head of the Refining Hall, he began to prepare for refining the Natal Demon Sword.

According to the refining method, he threw the gloomy gold and those auxiliary materials into the solid void array on the oven. Then control the oven flame to surround the solid void array. Let the various materials inside be refined by fire.

The flames burned for three days, and the gloomy gold did not change, while the other auxiliary materials had completely melted.

The gloomy gold is encased in a liquid of materials and is absorbing the properties of these materials, and the waste residue is automatically removed.

After another two days, Ning Chen extinguished the flame of the oven. Put the gloomy gold of various colors into the storage bag, and leave the alchemy hall to return to his residence.

"There are still eighteen days to go before the Inner Gate Competition, and I must hurry up and successfully refine the Natal Demon Sword. ”

"It's just a demon sword blood sacrifice with the blood of my Huangquan poison body, I don't know if anything will happen?"

"You can't care so much, let's talk about it first when the blood sacrifice is formed. ”

Ning Chen took out the colorful gloomy gold, and then used the magic sword to cut a wound in the palm of his left hand.

When the poisonous blood of the yellow yellow spring overflowed, he pressed his hand on the gloomy gold, and began to chant words in his mouth!

Due to his ability to recover from wounds, he had to use the magic sword to cut his palm many times during the blood sacrifice.

After a day and a night of blood sacrifice, the gloomy gold returned to its original color gray, and the surface shone with a faint luster. And the relationship between Ning Chen and Gloomy Jin has already formed a spiritual connection.

"Next, Divine Refinement!"

Divine refining is to infiltrate the Divine Consciousness into the Gloomy Gold on the basis of having a mental connection with the Gloomy Gold, and use the Divine Sense to depict the Spiritual Cultivation Formation inside the Gloomy Gold.

The Soul Cultivation Formation is the basis for refining spiritual weapons, and those who have reached the foundation building stage in the realm of non-divine consciousness cannot be portrayed at all.

Although Ning Chen was in the Jindan Great Perfection Divine Consciousness Realm, he didn't dare to be careless when he did this kind of thing for the first time.

It wasn't until two hours later that he breathed a sigh of relief and withdrew his divine consciousness from the gloomy gold, and the Spirit Cultivation Formation had been successfully carved.

Then, after another day of blood sacrifice, he began to carve the second formation for the gloomy gold, the Spirit Consciousness Array. The Spiritual Consciousness Array is a necessary formation for a growing spiritual weapon.

After successfully portraying the Spiritual Consciousness Array, it is necessary to leave a wisp of Divine Consciousness in the Spiritual Consciousness Array.

Then he began to depict the last formation, the Devouring Refining Array! This formation can make the growth spirit weapon devour the refining blood and soul, and promote the growth of the spirit weapon to improve the grade.

When the formation was described, Ning Chen used the mantra of refining the Natal Demon Sword to let the Demon Sword cultivate a weapon spirit while sacrificing blood.

Three days later, the machine spirit was finally bred, but at this time the machine spirit was very fragile and could be destroyed if it was not careful.

"Let's take shape first. Ning Chen silently recited the mantra, invaded his divine consciousness into the gloomy gold, and then according to the sword shape he liked in his heart, the gloomy gold changed, and finally formed a gray sword with a ghostly light!

"Boom!"

Suddenly, the sky began to darken, and thunder shook the sky.

Ning Chen's face changed, "This is a weapon robbery?"

He didn't understand why his Natal Demon Sword, which had just been successfully refined, had attracted a weapon calamity, and this Natal Demon Sword had only reached the level of a low-grade spiritual weapon.

But this was not the time to be entangled, so he immediately left the Alchemy Peak with his sword and flew towards a stone peak not far away.

The dark cloud seemed to have eyes, even if Ning Chen put the Natal Demon Sword into the storage bag, he couldn't dodge the weapon robbery, because this was the power of the law.

The dark clouds drifted above Ning Chen's head, the thunder was almost brewing, and the thunder was about to land.

Ning Chen couldn't care so much at this time, after all, his life was at stake. He immediately took out the Natal Demon Sword and threw it at the stone peak, and the sword quickly moved away from the stone peak.

The dense thunderbolt instantly landed on the stone peak, and the target was Ning Chen's natal demon sword.

Ning Chen's divine sense could not penetrate the thunderstorm and check the situation of the Natal Demon Sword. And his mental connection with the Natal Demon Sword was cut off under the thunderstorm.

"The weapon against the sky will attract the jealousy of the sky and descend the calamity. How can I look at this natal magic weapon that doesn't look like a heaven-defying weapon, does it?" Ning Chen frowned, his eyes fixed on the constantly descending thunder, and muttered.

At this time, there were already more than a dozen monks who had come to the Imperial Weapon, among which Ning Chen knew Gou Ling, the master of the Alchemy Hall, and Elder Gonghuo.

Gou Ling looked at the thunder and said in surprise: "This is a weapon robbery, who refined the weapon against the sky?"

"Hall Master, can you see what's going on inside?" Gong Huo asked, his divine sense couldn't penetrate the thunderstorm at all.

Gou Ling shook his head, "The thunder robbery has the power to eliminate the divine sense, and the old man can't see it." ”

After speaking, the flying sword under him flashed and arrived next to Ning Chen. "The dust boy is so close to death from the thunderbolt?"

"Ning Chen has seen Elder Taishang!" Ning Chen arched his hand.

"Go back to alchemy, in case you are affected by this thunderstorm, your ten heavenly destiny will not be enough for a thunderstorm!" Gou Ling said.

"This, report to Elder Taishang, this calamity is caused by the natal demon sword refined by the disciple. Ning Chen thought to himself, anyway, if he summoned the Natal Demon Sword out in the future, others would know about it, so he didn't plan to hide it.

"Natal Demon Sword? You said that you refined the Natal Demon Sword and caused this thunderstorm? Dust boy, you can't be fooling the old man, right? The main material of the Natal Demon Sword is gloomy gold, don't you tell the old man, you kid has the ability to get this kind of heavenly treasure!" Gou Ling was surprised at first, and then began to question. Even he didn't dare to think about the genius earth treasure of gloomy gold, Ning Chen was just a disciple of the tenth layer of qi cultivation, how could he get gloomy gold?

"Returning to the Supreme Elder, when the disciple was training in the place where the bones were buried, he found a gray stone with a glowing glow, so his curiosity was put into the storage bag. It wasn't until after returning to the sect that I checked the information and knew that this gray stone was gloomy gold, and the disciple happened to have seen the introduction to the refining of the Natal Demon Sword. I recklessly lost common sense to refine it, but I didn't expect that the natal demon sword was really successfully refined by mistake. However, as soon as the refining was successful, it attracted the weapon tribulation!"

When Gou Ling heard this, he was immediately speechless. He wanted to scold Ning Chen for destroying the heavens with his own strength, but the people really succeeded in refining, and it attracted a weapon tribulation, which showed that it was not an ordinary natal demon sword, but a weapon against the sky.

Just waiting for Gou Ling to say something. Suddenly, a thick thunderbolt struck the stone peak in an instant, shooting the stones on the stone peak everywhere. Gou Ling grabbed Ning Chen and quickly dodged the range of the stone peak with his sword.

The thunderstorm stopped, and the dark clouds quickly dissipated! The situation on the stone peak began to be revealed.

Everyone saw that on the messy stone peak, a small gray sword three inches long emitted a faint mystical light and stood in the air.

Everyone's divine sense swept to the gray sword, and their faces suddenly changed. Because they found that their divine consciousness touched the body of the small gray sword, they began to be devoured. They quickly withdrew their senses and became afraid of the Gray Sword.

"You kid doesn't know what luck you go, but you can actually refine this kind of anti-heaven weapon. Gou Ling said to Ning Chen with some jealousy.

"Hehe, disciple, this is a blind cat that ran into a dead mouse, and it was just a mistake. Ning Chen grabbed his head and said, then waved at the gray sword. The gray sword flashed in front of him in an instant!"In the future, you will fight with me, and I will call you the Huangquan Demon Sword!"

The Huangquan Demon Sword shook a few times full of spirituality, as if it was responding to Ning Chen.

"This sword is not simple, the natal demon sword has growth, your sword has been tempered by the thunder and thunder, and it has reached the grade of a high-grade spiritual weapon at the beginning. Dust boy, if it weren't for the Natal Demon Sword, others wouldn't be able to recognize the master, I would have wanted to snatch it. Gou Ling said seriously.

Ning Chen knew that he was not joking, but true words! But fortunately, once the owner of the Natal Demon Sword died, the Natal Demon Sword would immediately blow itself up and be martyred! Therefore, others could only covet the Natal Demon Sword, but they would not do the snatching but useless thing.

"This sword has just been refined by the Thunder Raid, so you should hurry back and use the blood sacrifice method to refine the weapon spirit. Also, don't slack off on the way to alchemy. ”

"Yes, Elder Taishang!" Ning Chen put the Huangquan Demon Sword into the dantian in his body.

Gou Ling didn't talk to him anymore, and immediately beckoned the other dozen or so elders to go.

Ning Chen Imperial Sword returned to his residence and hurriedly summoned the Huangquan Demon Sword. He stroked the blade of the sword, a look of affection in his eyes.

Then his mind moved, and the Yellow Spring Demon Sword slashed his palm.

He began to sacrifice blood to him with his own poisonous blood of the Yellow Spring.
