However, once the Secret Treasure is used to possess the Instrument Spirit, the power that the Secret Treasure can exert will rise to several levels.

Because of this, some amazing and glamorous warriors have developed an amazing way to use the spirit of the monster beast to create a tool spirit, after hunting the monster, use the secret method to extract the spirit from the body, seal it in the secret treasure, and spend some time to practice, it is possible to artificially make the secret treasure produce the spirit of the weapon.

This method is extremely bloody and cruel, and the process of sacrifice is also inhumane, and the demon beast spirit that is sealed into the secret treasure will taste unimaginable torture in the process of sacrifice, so once it succeeds, the secret treasure will become extremely evil, but compared with the orthodox instrument spirit, there is still a big gap between this kind of instrument spirit and the orthodox instrument spirit, although it can enhance the power of the secret treasure, but it is not so terrifying.

The success rate is also very low, and the time consumed is not short, so except for those who have cultivated the secret art of evil skills and have great patience, no one uses this method to create machine spirits, and these secret techniques are rarely mastered.

The artifact spirit that Yang Kai encountered this time was a genuine existence, not the kind of artificially created evil artifact spirit, it had no evil aura at all, it was clearly born from the refining furnace due to some coincidence.

Although the refining furnace is not a secret treasure used for fighting, its grade is not low, and the power emitted by the strange bird weapon spirit made Yang Xingxing jump for a while.

Seeing it rushing towards him, Yang Kai only had a fiery red color left in front of him, as if the entire stone room was filled with that incomparably pure fire aura, and he could no longer see anything else.

I hope this guy has only been born for a short time, and he hasn't turned on his mind. Yang prayed secretly happily.

At the same time as the body retreated sharply, the purple shield was sacrificed at the same time, and the Saint Yuan frantically poured in, and a violent sandstorm suddenly appeared, surrounding Yang Kai's body for protection.

But the sandstorm had just appeared, and the crimson firebird spread its wings and rolled up a more ferocious sudden wind, and one after another fire-knife-like attacks were mixed in the sudden wind, and it was only a breath to break through the sandstorm's protection.

The wind fuels the fire. Fire borrows the power of the wind. The firebird was terrifying, Yang Kai's breath was stagnant, and he secretly said in his heart that something was not good, and a demonic flame long sword instantly appeared in his hand. Pitch-black swords slashed out. The momentum is like a rainbow.

Bang bang bang......

A loud noise was heard. The red fire knives and swords got along, and they all died together, but the fire knives were endless. There were countless of them, and there were quite a few sword rays cast by Yang Kai, but they still couldn't cancel them all out.

The random blow of this red firebird is incredibly powerful!

Yang Kai made a move, and the Baiyue Diagram appeared leisurely, and the phantoms of the mountain peaks flashed out of the diagram, flying towards those fire knives.

A trace of disdain and mockery flashed in the two eyes of the Crimson Firebird, and the wings were graceful again, and the fire knives that had not yet been destroyed turned into fire snakes like a psychic, bypassing the phantom of the mountain peak of the Baiyue Diagram, and heading straight for Yang Kai himself.

After seeing that humanized look, Yang Kai sighed in his heart and secretly complained.

This machine spirit not only has a sanity, but also a sanity that is not low, otherwise how could it show that kind of expression?

What's more, since this thing was born from a refining furnace, it should be inherently proficient in the laws and supernatural powers of the fire system, and it was really not a wise move to fight it in such a small stone room.

Yang Kai instantly had the intention of retreating.

At the same time that the black fireballs were knocked out of the calamity, Yang Kai's divine thought moved, and the Yuan Control Technique unfolded, which also turned into a series of fiery snake-like attacks, heading towards the firebird.

The two strange snakes quickly collided together, one red and one black, constantly gnawing and devouring each other, and there was a bit of a stalemate.

Taking advantage of this opportunity, Yang Kai was about to retreat, he didn't want to fight with such a machine spirit here.

How did he know that the firebird's mind was extremely flexible, and when he saw Yang Kai's movements, he knew what he wanted to do, his head tilted, and a fireball the size of a basin erupted from his mouth, and the fire-based aura contained in this fireball was violent and ferocious, Yang Kai was startled when he saw it.

If you are hit by this thing, you will be seriously injured if you don't die, so you hurriedly dodge to the side and dodge.

The strange bird seemed to know that Yang Kai would have this kind of reaction, and the ridicule in his eyes was even stronger, and the fireball rushed into the entrance of the passage that Yang Kai walked into, bursting violently, but the fire aura did not dissipate, but instead turned into a layer of red and brilliant light curtain, sealing the entrance of the passage.

Yang Kai's face sank!

The crimson firebird was trying to trap him here, and he didn't want to let him go.

In normal times, such a layer of obstacles that were simply laid out would naturally not be able to stop Yang Kai, and it would only take a little effort to break through it, but a machine spirit in front of him was eyeing him, how could Yang Kai have the strength to break through that layer of red light curtain?

Once this is done, it will only give the machine spirit a chance to take advantage of it.

"Silly bird, you will die by yourself!" Yang Kai's face turned pale, and he didn't want to retreat, the demonic flames outside his body were tumbling endlessly, and the whole person was like a raging black fireball, the pitch-black color seemed to be able to incinerate everything, it seemed that even the line of sight could be incinerated away, and no one here could see Yang Kai's true face clearly.

Seeing that Yang Kai was angry, the sneering look of the red monster bird disappeared, and he seemed to understand that he seemed to have done something bad, the person in front of him was not a soft persimmon that could be kneaded casually, and it was not a wise move to forcibly leave him behind.

However, it was just a machine spirit, although its divine mind was opened a lot, it didn't think too much, and with a scream in its mouth, the invisible impact tore through Yang Kai's defense and rushed straight at his divine soul.

Knowing the sea, turning over the river and the sea, there was chaos, Yang Kai snorted coldly, suppressed the strange state of the sea of knowledge, and between the dancing of his hands, the black mangs in the entire stone room were flourishing, and the energy transformed by the demonic flames continued to overflow from Yang Kai's body, and soon occupied half of the country, fighting against the pure fire aura of the red firebird.

The situation in the stone room suddenly became extremely strange, the half near the entrance was pitch black, and the five fingers could not be seen, while the other half was red and hot, like a sea of fire.

The two energies collided fiercely towards each other under the urging of Yang Kai and the Crimson Firebird.

The entire stone chamber shook in an instant, and the aftermath of the fierce collision of energy hit it in all directions, and at the stone wall, a series of forbidden lights flashed, intercepting these aftermaths.

Fortunately, this place was the place where the most outstanding refiners of that great sect refined their weapons, and they had already been placed with layers of prohibitions, otherwise such a stone room alone would not be able to withstand the battle between Yang Kai and the Instrument Spirit.

The black light and the red light continued to collide, and they did not back down from each other, melting little by little.

Yang Kai's face was solemn, and the graceful body of the Crimson Firebird was constantly writhing, and the strange screams in his mouth were endless, and there was no longer the previous ease and freehand.

The collision of incense time lasted for a long time, and the stone room returned to its original appearance, Yang Kai and the machine spirit looked at each other from afar, and they all hit a real fire, and the hard collision just now, no one was helpless.

Yang Kai couldn't have imagined that just a single instrument spirit could be able to tie with him! His own combat strength, he knew better than anyone else, even if he encountered a strong person who had returned to the void realm now, as long as the other party was a little careless, Yang Kai was confident that he would be severely injured, as for whether he could kill him, it depended on the other party's means.

But this machine spirit is not inferior to himself at all.

This is just a machine spirit that is not driven by the owner.,Can't exert the full power of the machine spirit.,If it's collected by someone and someone controls it.,I'm definitely not an opponent.。

Because the machine spirit is not an entity, the existence of the machine spirit is only to enhance the power of the secret treasure.

I'm fighting so hard, I'm just fighting with the shadow of that secret treasure, if ......

When Yang Kaizheng was thinking like this, his face changed, his expression became much more solemn, and without thinking about it, hundreds of Heavenly Shields instantly appeared in front of him, and at the same time, he sacrificed the purple shield out of the sky.

Because the spirit seemed to be berserk, the refining furnace that was originally quietly placed in the center of the stone room also buzzed because of its fury, and in an instant, the refining furnace actually flew into the air on its own, spinning and spinning, and clusters of extremely agile flames flew out of the refining furnace and drilled into the body of the firebird.

In an instant, the firebird's momentum skyrocketed, and a solemn feeling swept away.

Yang Kai's face was wonderful, and he exclaimed: "Potential!"

Such a machine spirit actually knows how to use the power of the potential that only the powerhouses of the Returning Realm can comprehend.

Didn't Qian Tong say that in the Flowing Flame Sand, there can be no potential at all? Once a martial artist who has comprehended the strength of the potential enters, he will be wiped out in an instant. It is precisely for this reason that the powerhouses of the Returning Void Realm cannot enter the Flowing Flame Sandland, and the opening of this forbidden land in previous times has only been entered by the martial artists of the Saint King Realm.

But this strange bird actually used the power of the potential, and there was nothing to do.

However, Yang Kai soon sensed that something was wrong, this kind of power was somewhat similar to potential, but it was not potential, but a magical means for the firebird to catalyze the rich fire aura in this stone chamber and use the aura of heaven and earth for his own use.

It was worthy of being a fire-based weapon spirit, and sure enough, he was born to be proficient in these laws of heaven and earth, Yang Kai was secretly frightened.

This was the second time that Yang Kai had fallen into this kind of similar force envelope, the last time was outside the cave of Dragon Cave Mountain, fighting against a Returning Void Realm powerhouse beside Xie Hongwen.

However, the other party's momentum is simply vulnerable compared to the current situation. The last time he was wrapped by that person's momentum, although Yang Kai's actions were contained, it was not a big problem.

But Yang Kai felt extremely heavy all over his body at this moment, his bones made a clicking and dislocation sound, his body was shaky, and it was extremely difficult to even move his fingers.

It was as if there was an invisible restraint around him, turning into invisible chains, locking him firmly in place and making him unable to move.

Even the Divine Consciousness and the Divine Element were condensed in the sea of consciousness and the body, and they could not use a single bit! (To be continued......
