The hole is not deep, just more than ten meters deep underground, just enough to accommodate a person to meditate and practice, Zhou Wu has checked, this hole is artificial, there are traces of chiseling, Zhou Wu guessed, it should be other monks, in order to be able to stay in the sea of death and fire to cultivate, can dig out of the hole.

Being in the cave, the flames can't pour in at all, because there is no gout in the cave, the air content is very low, and the monk, when he reaches the realm of returning to the void, he can rest inside, with Zhou Wu's cultivation, he can stay in the cave for two hours at most, and Zhou Wu also has his own way, he has an iron box, which can provide oxygen for Zhou Wu at any time, so even if he stays in the cave for a longer time, he doesn't need to worry about being suffocated in the cave.

Zhou Wu sat down directly in the cave, running the flame technique, and in an instant, around the cave, the flames within a radius of dozens of miles were all surging towards the cave.

With the cave as the center, the flames continued to gather towards the cave, and Zhou Wu in the cave enjoyed this extremely fast cultivation speed very much, driven by the flame technique, although the fire energy inhaled into the body was mixed with the flames in the sea of death, but there was a flame technique, refining these flames was easy.

In just one month, Zhou Wu's cultivation was upgraded one after another, and he entered the eighth-layer realm of the Jindan realm, among the three Jindan, the fire Jindan was currently the largest, followed by the golden Jindan, and then the purple Lei Dan.

Since he had three golden pills, Zhou Wu found that each golden pill was related to every kind of exercise he cultivated, when cultivating the Fulong Jue, the golden golden pill was mostly enhanced, and when cultivating the flame technique, the red fire pill was mostly enhanced, but no matter which kind of exercise was cultivated, the three golden pills would make progress.

Three months later, Zhou Wu's cultivation, like riding a rocket, approached the peak of the ninth layer of the Jindan Realm, being in the sea of fire, the nine-rank spiritual root, and the top-level exercises, which was Zhou Wu's innate advantage.

Feeling the surging true qi in his body, Zhou Wu was full of confidence, at this time, he was in the sea of fire, his body was burned naked, naked, but fortunately, the flames were strong, and he couldn't see the embarrassing picture clearly.

Leaving the cave, Zhou Wu shuttled through the sea of death fire like this, like a flame spirit, not affected by the extremely flame of the sea of death fire at all.

At this time, Zhou Wu was in the sea of fire, like a fish playing in the water, if outsiders saw it, they would be scared half to death, after all, in the hundreds of thousands of years of history of this continent, no one had ever dared to wander in this sea of death and fire, as strong as the fire spirit root Mahayana realm, and he did not have this ability.

While wandering, Zhou Wu sensed the temperature change in the sea of fire, he always ran towards the place where the temperature was the highest, but after changing dozens of places, there were always other places where the temperature was higher than the place he came.

For a year, for a whole year, Zhou Wu wandered in the sea of death fire, and Huoyun had collected a lot of fire attribute materials, including materials that could refine seven-grade and eight-grade pills and many materials for refining Horcrux Dao weapons, all of which were prepared for the Alien Dragon Gate.

And Lei Yue, who has found a place, has been quenching his body, and he can't break through due to the influence of supernatural powers, but if he can have a more terrifying physique, then he can ignore the impact of supernatural powers.

And Lei Yue's body, on this continent, is already considered to be the top, and it is impossible to make a breakthrough, but he did not give up, trying to refine his body with the help of the extremely flame flame of the Sea of Death, but after a year, he had little effect.

"It's been a year, it's been a whole year, is there anything I need in this sea of death? I've searched half of the sea of death fire, and I don't have any clues, is it possible that Uncle Lei and his master's judgment is wrong? Zhou Wu began to question his own judgment.

It stands to reason that the core is missing from the Yang Sword, and if it is in the Sea of Death and Fire, then it must be a hot place, but he has searched for many places with extremely high temperatures, but he has not found it.

Just when Zhou Wu didn't have any clue, he had an idea, and hurriedly sacrificed the Yang Sword.

"Since it is the missing accessory on the Yang Sword, then, it must have something to do with the Instrument Spirit, the Yang Sword has not awakened the Instrument Spirit so far, that means, the missing part is the Instrument Spirit, if it is really the Instrument Spirit, then, as long as it senses the breath of the Yang Sword, why do I need to look for it, wait for it to come to me by itself, isn't it?" Thinking of this, Zhou Wu sat down directly, ran the true qi, and injected it into the yang sword, and suddenly, a strong flame emanated from the yang sword, and the yang fire jumped up hundreds of zhang high, and the surrounding flames actually surrounded the yang fire, and a large area surrounded it, with the yang fire as the head, there was a tendency to bow down.

"Yang Huo can actually cause such a strong reaction, it seems that my guess is right, and the next thing is to wait." Zhou Wu looked confident.

Outside the Death Flame, there are countless strong people standing, they are all cultivators who are exploring in the outermost part of the Sea of Fire, for some reason, the flames in the Sea of Death Fire suddenly become extremely violent, and the monks who are as strong as the Mahayana realm can't bear the violent flames, so they retreat one after another, and even Lei Yue also withdrew from the Sea of Fire.

"What's wrong with the Sea of Death? Why did the flames suddenly become so violent? ”

Dozens of strong people gathered together, including Huoyun and Lei Yue, the two glanced at each other, looked around, and did not find Zhou Wu's figure, they probably had a bottom in their hearts, and Zhou Wu had the mark of the Fire God, they were not worried about Zhou Wu's safety at all.

"I don't know, this sea of death fire has been stable since the beginning of its formation, but why did it become so violent this time? Could it be that there is a treasure about to be born in the sea of death? ”

As a strong person, when encountering such an abnormal thing, the first thing to think of is the birth of a treasure, and although this extremely flame flame becomes violent, it is not an anomaly, but it is also very abnormal.

"Treasures are born with visions, but the flames just become violent."

A group of strong men were talking about the Sea of Death Fire, and Lei Yue and Huoyun stood together, with a smile on their faces, they probably guessed that this Sea of Death Fire had become so violent and had a direct relationship with Zhou Wu, but they were not sure whether Zhou Wu had found what he needed.

In the sea of death fire, Zhou Wupan sat in place, the yang sword was suspended above his head, and the yang fire emitted from the yang sword jumped up a hundred zhang high, and the flames of the entire sea of death fire became violent, with Yang Huo as the leader, bowing down to the subordinate.

In a corner of the sea of death, I saw a man with flames burning all over his body and said fiercely: "It's been hundreds of thousands of years, you still found it after all, I want to see what kind of heir you have chosen." After speaking, the flame man turned into a flame, merged into the extreme flame flame, and ran in the direction of Zhou Wu.

Zhou Wu has been sitting upright for ten days and ten nights, the surrounding flames are still worshipping around the yang fire, Zhou Wu seems to have his eyes closed, but has been exploring the surrounding movements, he found that there is a wisp of flame revolving around the yang fire, and there is no awe, Zhou Wu is observing this wisp of flame, and the flame naturally also noticed Zhou Wu.

"Hundreds of thousands of years, you have chosen such a human successor? The peak of the ninth layer of the Jindan Realm, moreover, this kid seems to have a variety of spiritual roots in his body, Moreover, I feel the inheritance of other gods in him, and there is more than one, is it possible that the great fire god wants to snatch the heir with other inheritors? No, if I want to return to the Vulcan Sword, I must erase the other two inheritances on him, and the incumbent, such a weak inheritor, is not worthy of the Vulcan Lord's inheritance at all, wipe you out, and find someone else to inherit. ”

With a whoosh, this wisp of flame rushed towards Zhou Wu.

Zhou Wu suddenly opened his eyes, his eyes were full of raging fire, I saw him raise his hand, the Yang Sword fell into his hand, and in an instant, Zhou Wu's body was wrapped in Yang Fire.

"I've been waiting for you for a long time! Finally willing to show up! Zhou Wu blocked the Yang Sword in front of him, and when the wisp of flame saw this, he hurriedly stopped his body, and his body exploded dozens of feet, and from a distance, he revealed his true face, only to see a person with flames burning all over his body appear in front of him.

"Humph! Such a small human being can actually get the favor of Lord Vulcan, I really can't figure out why my master chose you to inherit the throne of the Vulcan! The flame man said disdainfully.

Zhou Wu sneered: "This has nothing to do with you, you just need to return to the Yang Sword, Instrument Spirit." ”

The flame man's face sank and he said, "How do you know that I am the weapon spirit of the Fire God Sword?" ”

Zhou Wu said: "I still have at least two immortal weapons that are better than the Yang Sword, and they all have instrument spirits, but the Yang Sword does not, so what the Yang Sword lacks is the instrument spirit." ”

When the flame man heard this, his eyes suddenly spurted out a strong killing intent, this guy's strength is not inferior to the power of nature at all, Zhou Wu knows that the flame man is the same as the power of nature, he already has an independent consciousness, and his strength is not under the power of nature at all, it's just, like a good iron box, Yang Jian is born to restrain the flame man, this guy is originally the instrument spirit of Yang Sword.

The flame man roared, "No! I'm not a machine spirit, you see, this whole sea of death fire, it's all mine, it's all mine, hahahaha. The flame man laughed maniacally.

Zhou Wu nodded: "At the beginning, when I subdued another machine spirit, she also created a world, but the world she created, the singing of birds and flowers, gave birth to many living beings, and you?" You will only bring destruction, you see, this radius of thousands of miles, all affected by you, the lives are devastated, there is no living creature can survive in this extremely hot environment, you are too selfish! ”

Being scolded by Zhou Wu, the flame man's temper suddenly burst out, and he rushed towards Zhou Wu, the momentum, like a tsunami, hundreds of zhang high flames, even more turbulent than a tsunami.

Standing in front of that high wall of fire, Zhou Wu looked extremely weak, he couldn't stop this flame at all, even if he had the mark of the god of fire.

At this time, Zhou Wu's mind thought quickly: Lao Tie once said that all immortal weapons with different fire as the core, the instrument spirit and the different fire can be fused, and the thundering fire and the instrument spirit of the Thunder Immortal Mansion are perfectly integrated, and the tool spirit of the iron box, without the support of the different fire, fell next to me and sucked my first breath, before transforming into my appearance, he also said that the different fire can have a completely restrained effect on the homologous instrument spirit, and if you want to deal with this flame man, you can only rely on yang fire.
