The design of the new version of the Heavenly Needle did not delay Lu Yunze for much time. It only took a few days for Lu Yunze to come up with the design.

After all, Lu Yunze's weapon refining skills have now reached a completely different level. In addition, this time he used ready-made design drawings to make changes, so the speed is naturally much faster.

After checking the design drawing several times and confirming that there were no problems, Lu Yunze was ready to start refining the new magic weapon.

Han Li had already had an affair with Lu Yunze before. This time, the two of them were in seclusion for a few years, sorted out their gains, and then prepared to go hunting monsters.

Therefore, Lu Yunze did not make the design of the Mitian Needle too complicated, but simplified the process as much as possible while retaining its own power.

Lu Yunze was quite satisfied with the final product. According to his estimation, it could be refined within a year. After another two or three years of slowly warming up, it would be almost ready for use.

After pondering for a moment, Lu Yunze no longer hesitated and began to carve a huge formation on the ground.

This formation was full of evil. Before Lu Yunze could finish drawing it, there was a hint of evil aura. If an ordinary mortal were here, if he were aroused by this evil aura, he would immediately bleed from his orifices and collapse his mind.

Finally died of madness.

Even those who are cultivators of immortality will feel frightened here, and their souls will be at risk of being contaminated if they stay here for a long time.

But Lu Yunze was not affected at all. A grayish aura flashed across his eyes, and his body was suddenly filled with traces of evil aura, which instantly suppressed the evil aura of the formation.

When it comes to evil spirits, how can a mere formation compare with him?

After completing the formation, Lu Yunze secretly breathed a sigh of relief and fired out a spell with one hand. The formation was instantly filled with traces of black energy, and there was a faint sound of howling ghosts and wolves.

Lu Yunze jumped out of the formation, thought with some hesitation, and then took out a black alms bowl and a small jade box from the storage bag.

He flipped one hand over, and a large area of ​​pitch-black demonic fire instantly emerged from the alms bowl and disappeared directly into the formation.

In an instant, the sound of ghosts crying and wolves howling loudly arose, and the black energy in the formation seemed to have received some great tonic. It roared up violently, like a huge black tentacle, tumbling in the formation.

Lu Yunze nodded with satisfaction. These days, the corpse fire was collected by him when he was fighting Ji Yin, so it is just right to use it here.

The black energy tossed around in the formation for a while, and then gradually calmed down.

Lu Yunze also opened the jade box in his other hand, revealing a black fire lotus.

This is the trophy when he killed King Luo of the Ghost Spirit Sect, the famous magical power of the Demon Flame Sect Xuanhuo Boy, Netherworld Xuanhuo!

Back then at the border of Yue Kingdom, he watched with his own eyes as the Xuanhuo Boy relied on this demonic fire to overwhelm the monks of the same rank who were holding two ancient treasures and could not breathe.

At that time, Lu Yunze was quite envious, and for the first time he had a clearer understanding of the power of the demonic fire.

Later, he obtained a copy of the Demon Flame Sect's "Burning Heaven Sutra" from Wang Lianhua, the daughter of the Demon Flame Sect's master, and thus learned that these demonic fires require matching techniques to fully utilize their power.

Bring it into play.

If the skills do not match, not only will the power of the demonic fire be unable to be fully exerted, but the monks themselves may be affected by the demonic fire. The consequences may range from being unable to advance in cultivation to being obsessed, losing consciousness, or even exploding to death.

It can be said to be extremely serious.

Even the well-informed Master Xuan Gu could not refine the mysterious soul Yin Fire that he cherished while he was still alive. He could not refine this fire until he turned into a ghost cultivator. Therefore, Lu Yunze naturally stopped fighting.

This is the idea of ​​Netherworld Mysterious Fire.

But now seems to be a good opportunity. If he can refine it into a magic weapon, then he may be able to avoid the influence of the magic fire on the monks and indirectly activate the power of the magic fire.

Seeing the black energy in front of him that had completely calmed down, Lu Yunze no longer hesitated and directly threw the jade box containing the Netherworld Fire into the formation.

This time, Heiqi's reaction was far less terrifying than before. He just made a low muffled sound, and then there was no movement.

Lu Yunze frowned strangely and looked carefully, only to suddenly realize that the black energy had completely turned into wisps of substantial black flames.

This change was somewhat unexpected to Lu Yunze. After thinking carefully for a moment, he suddenly took out a buzzing green dagger from his storage bag.

This magic weapon seems to have been left by some unlucky pill-forming monk. At that time, he thought the refining method was interesting, so he kept it. Now it can be used for testing.

Lu Yunze threw it with one hand, and his powerful spiritual consciousness directly suppressed the spirituality of the magic weapon.

The magic weapon immediately let out an unwilling cry, but in the blink of an eye it was suppressed by Lu Yunze's consciousness and flew straight into the formation.

In an instant, substantial black flames rose up, like a ferocious big mouth, swallowing the dagger in one gulp.

The dagger let out a mournful cry, its light dimmed for a moment, and it didn't take long to disappear into the black flames.

This scene made Lu Yunze slightly stunned, and then his eyes widened in surprise!

The Tiandu Corpse Fire was conceived from the corpse fire inside the refining corpse combined with the Xuan Yin Demonic Qi, while the Nether Xuan Fire was made by the Xuan Huo Boy using the souls of monks to sacrifice. The two merged into one, and it seemed that some benign things had happened.

The mutation makes its power even higher.

Although he was pleasantly surprised, Lu Yunze also did not forget to knead the secrets and chant the mantras, and produced several magic formulas.

The entire formation suddenly made a strange muffled sound, and the wisps of black flames stirred up like water waves, turning into strands of black air again.

Seeing this, Lu Yunze quickly picked up a storage bag at his waist and fell down.

Hundreds of thousands of iron fire ant corpses poured into the formation like a black wave.

The traces of black energy seemed to have found prey in an instant, scrambling to burrow into the body of the iron fire ant. In the blink of an eye, the inside of the formation was filled with surging black energy, and there was a faint sound of being gnawed by thousands of flying insects.

The sound of flesh and blood makes people shudder when they hear it.

Lu Yunze meditated on the spot, watching the strange scene in front of him without saying a word.

This step is a piece of work. You only need to wait for the black gas to combine with the corpses of the iron fire ants before you can start the next step.

Before that, Lu Yunze took out a blue bead with a lotus pattern engraved on its surface from his storage bag, looking a little thoughtful.

The corpse fire of Tiandu, the mysterious fire of the netherworld, and the natal black flame of the iron fire ant are all combined into one, and the power of the demonic fire produced must be astonishing.

Coupled with the refining method of Tiandu Corpse Fire and Mitian Needle to compress and condense it, I wonder if the final product can be comparable to this dry blue ice flame?

As he thought about it, Lu Yunze couldn't help but think of the ghostly holy fire that existed in Xuan Gu's memory.
