Seeing that Yang Kai was easily trapped, the firebird once again showed a smug and disdainful expression, opened its mouth, and a sharp flame turned into a sword-like attack, heading straight for Yang Kai's front door, the speed was as fast as thunder, and the power was unstoppable.

It seemed that it wanted to take the opportunity to take Yang Kai's life.

Click......

The hundreds of Heavenly Shields guarding in front of Yang Kai shattered in response, and the purple shield was only blocked for a moment, and the purple rhyme on the surface suddenly dimmed, looking like a spiritual failure, and it was directly knocked to the side and fell to the ground.

In the blink of an eye, the fire sword rushed in front of Yang Kai, seeing that Yang Kai's life was about to be guaranteed.

At this moment, a pitch-black blade-like attack flew out from in front of Yang Kai, and that blade seemed to tear the space apart, silently, without the slightest energy fluctuation, very secretive.

Space Blade!

Yang Kai paid for himself with his own divine sense and the means used by the Holy Yuan, but he couldn't compete with this instrument spirit, and it actually knew how to use that refining furnace to fight the enemy, which greatly surprised Yang Kai.

The machine spirit itself is extremely difficult, and now it drives the furnace that gave birth to it, and the ferocity is even more ferocious, and if it continues to fight like this, it is tantamount to looking for death!

So Yang Kai didn't hesitate to use his killer weapon.

He is still quite confident in the Spatial Blade, although the means of the machine spirit are extraordinary, and he is naturally proficient in the laws of the fire system, but the spatial force is a kind of extremely remote and powerful force, in the space law, Yang Kai also has a lot of experience, although it is not a great success, there should be no problem in dealing with a machine spirit.

Really. After the spatial blade met the fire sword, the blade-like crack twisted for a while, and it was unstable by the powerful fire aura, and it quickly disappeared, but before it disappeared, it also swallowed the fire sword into the void crack.

Yang Kai's crisis was lifted in an instant.

Without waiting for the machine spirit to make any more moves, one after another spatial blades took shape leisurely, half of them flew towards the machine spirit, and the other half circled around Yang Kai's side, suddenly. The amount of force that restrained Yang Kai seemed to have been cut off. He was set free.

The moment Saint Yuan was able to urge, Yang Kai immediately stepped back, and with a wave of his hands, a foot-long spatial blade had already flown out. Swallow a hole in the red light curtain that has been blocking the passage. The opening is small. But it was enough for Yang Kai to pass safely.

In the next moment, Yang Kai's figure had already rushed into the passage that was hundreds of zhang long, and there was an angry roar from behind him.

The other party was obviously forced by the spatial blade to be in a hurry. Yang Kai, who had no time to take care of retreating.

Yang Kai didn't expect his spatial blade to be able to kill that instrument spirit, the fire aura driven by the other party was pure and majestic, and it was not something that the current spatial blade could completely devour, so he was very satisfied with the surprise of the other party and creating a chance to escape.

For now, it is to leave this earth lung fire pool quickly, find another place to refine Xuanyin Kwai Water, and wait until the strength is improved, if there is still time, come to find trouble with it.

As Yang Kai expected, he had just rushed out of a distance of less than a hundred zhang, and the firebird seemed to have intercepted all the spatial blades, and immediately a scorching aura came from behind him.

Yang Kai was busy, and when he looked back, he suddenly felt a dead soul.

In the distance of the passage, the machine spirit was wrapped in a ball of red light, and it was in hot pursuit, unwilling to let him go at all.

The entire passage was extremely hot, and before the firebird itself arrived, the rich fire aura had already spread, and the stone walls around the passage melted all at once.

Yang Kai's footsteps did not stop, the speed was a few points faster, compared with this kind of inherently disembodied machine spirit, the speed was still slightly insufficient, seeing that the exit of the passage was in sight, but the distance between himself and the machine spirit was getting closer and closer, Yang Kai's eyes flashed a trace of cruelty, and when he was about to turn around and give the machine spirit a blow, there was a strange cry of a firebird from behind.

There was a sense of reluctance and anger in that cry, and at the same time, the fire aura that permeated the entire passage quickly retracted like the ebb tide of the sea.

Yang Kai was surprised, turned around again, his eyes showed surprise, not only did he not run, but he stopped his pace and looked over there with interest.

At a distance of about fifty zhang from him, the firebird fluttered in the air, but at this moment, a chain-like energy bar appeared on its body, and the runes on the chain flowed, which was a forbidden technique at a glance, wrapping the firebird's whole body and binding it to death.

It only screamed a few times, and the chain snapped into the firebird's body.

The unwillingness in the firebird's eyes became even more intense, but with a bang, its body exploded, turning into a little fluorescence and disappearing.

Yang Kai frowned, thought about it, and hurriedly released his divine thoughts, and probed into the stone room to investigate.

In the stone room, the refining furnace that was originally suspended fell down again, and it was quiet, returning to the state when Yang Kai first came in, but the strange bird pattern on the refining furnace still existed, but it was a little different from before, the strange bird pattern seemed to be irritable, constantly swimming and flying away on the surface of the refining furnace, but it never left the refining furnace.

Yang happily grinned.

It turns out that that thing can't be too far away from the refining furnace, once it is far away, it will definitely be taken back by the refining furnace, which is no wonder, after all, the firebird is the spirit of the refining furnace, and there will naturally be some involvement between the two.

After making sure that the machine spirit couldn't do anything about himself, Yang Kai secretly exhaled and wiped the cold sweat from his forehead.

The battle just now was really the most dangerous one he had encountered, even if he fought with the Returning to the Void Realm master brought by Xie Hongwen last time, he could handle it with ease, and he wouldn't have any worries about his life at all, after all, there was Yang Yan's formation assistance at that time.

But this time, he was forced by the machine spirit to fight him in that stone room, and Yang Kai could almost be said to have exhausted his means except that he did not use the Demon Eye of the World Destroyer, and he still had to flee in embarrassment.

That is, he can escape his life from the hands of that instrument spirit, and if he comes here as another Saint King Realm, there is a chance that he will die on the spot.

Standing in the passage for a moment, Yang Kai thought to himself, since the machine spirit could not chase out of the stone chamber, then there was no need for him to leave the Earth Lung Fire Pool, this was a rare treasure land, although the environment outside the fifth layer was good, compared to this place, it was a small thing, and there was no comparison at all.

However, Yang Kai didn't dare to enter this stone room, but he could go and see another stone room at the lowest level.

Yang Kai didn't believe that there was still a machine spirit there, it was a fluke that this kind of thing could give birth to one, and it was absolutely impossible for a second one to appear.

If it really appeared, Yang Kai could only go to the upper layer and give up this bottom.

Thinking like this, Yang Kai turned around and walked towards the outside of the passage, leaving the passage in a short moment, stepping into the hole on the right.

Like the previous wall cave, the passage in this wall cave is also more than a few hundred zhang long, and after passing through the passage, there is a magnificent and huge stone room.

Although he didn't think that there would be a second machine spirit, Yang Kai still didn't dare to be too careless, and stood at the entrance of the passage to investigate carefully, and only then did he breathe a sigh of relief when he found that the Void King-level refining furnace in the center of the stone chamber had been burned down.

Even the refining furnace has been destroyed, so naturally there is no way that any instrument spirit will be born.

When Yang Kai's gaze swept over some of the aura-like ores and refining materials piled up on the side, his eyes suddenly brightened, and he hurriedly rushed over and checked them one by one.

Sure enough, if you don't die, there will be a blessing in the future, he didn't expect that in this most difficult stone room, there are so many refining materials piled up.

And the grades are very high, at least they are also imaginary-level quality, most of them are virtual-level king-level, all kinds of rare ores, five-element metals, and the body materials of demon beasts, which are dazzling and dazzling.

Although there are many materials, some of them can no longer be used because they have been stored for too long.

Yang Kai picked and chosen, put away all the materials that could still be used, and discarded those that could not be used, then he clapped his hands with satisfaction and continued to look at this stone room.

The layout is almost the same as the stone chamber on the left, with a refining furnace several feet high in the center, and several white balls inlaid around the stone wall, exuding a soft light.

However, there seem to be fewer light balls here, only four, and there are not as many as the eight in the other room, it seems that the owner of this stone room is a little inferior to the master of the stone room on the left.

Yang Kai didn't delve into these either, he found the four stone piers, and each punched in a Saint Yuan to close the formation of the stone chamber.

After waiting for a long time, he came to the destroyed refining furnace and unceremoniously put it into the space ring.

Although this refining furnace is damaged, it is a virtual king level after all, bring it back and let Yang Yan take a look at it to see if she can repair it, if it can be repaired, it can be used, it doesn't matter if it can't be repaired.

He had already collected several damaged Void King-level refining furnaces before.

After collecting the refining furnace, a clearing appeared in the center of the stone room, and an independent magic circle was also engraved on the open space, although the area was small, but it was extremely complicated, although Yang Kai was not proficient in the way of the formation, but after going in and out of hundreds of stone rooms, and closing so many magic circles, he could also understand that this formation was one of the ways used to convert the pure fire power in the earth lung fire pool into the refining furnace.

Moreover, the four stone piers around it also have a great effect, depending on the number of forbidden openings in the stone piers, the speed and power of extracting the fire from the center of the earth are also very different, and the relationship between the two is proportional.

In other words, the prohibition of opening four stone piers is completely different from opening one and extracting the fire from the center of the earth.

This design made Yang Kai very satisfied, and secretly felt that the masters who arranged these means were really extraordinary.

The delay had been long enough, Yang Kai was not ready to delay any longer, and with a shake of his body, the person had already come to the original position of the refining furnace and sat down cross-legged. (To be continued......)
