Twenty-three thousand four hundred miles below the entrance of the cave, Zhuang Wudao did not know what was happening in the outside world at this time, let alone that there were already three of the most extreme cultivators in the world who had followed his tracks and entered the Huoyun Cave.

The four fourth-order fire spirits when he first entered the cave that day were no more difficult for him than a sixth-order sword demon. However, in the snap of a finger, the thunder of the gods of heaven was destroyed and shattered together.

The most tricky thing about elves is their ability to resurrect. As long as there is a zài of the same kind around, it can be resurrected at any time.

But that's nothing to him. At the time of the Jindan realm, these things that still made him feel extremely tricky were no longer in Zhuang Wudao's eyes.

As the middle of the world. One of the two who are most fearless of group battles. An elf. It's actually no different from hundreds, thousands.

After entering, the road is also like a bamboo, under this fire cave, there are many fire demon beasts that inhabit and survive here, and there are many natural elves with the three attributes of earth, fire and gold.

However, Zhuang Wudao swept all the way, and no living creature could stop him at all. Those innate elves were all killed by him directly by him, and they all collected the essence of these innate alien objects. As for the other demon beasts, they sensed the aura of the ink spirit from a distance, so they knew how to avoid it.

For three days, Zhuang Wudao even deliberately connived and let the three-legged crow hunt. Naturally, the food is not those demon beasts, but those earth-based elves.

The three-legged crow is born and dead, but it is the essence of the earth system. It is precisely because the body is earthy, without the ethereal spirit of birds, it is far inferior to other divine birds in terms of speed. Therefore, the bloodline inheritance of the three-legged crow is inferior to the phoenix and the three-legged golden crow, and it is listed as a second-class divine bird.

But if you talk about combat power, in fact, the three-legged crow is not inferior to those top-level divine birds. And those wandering fourth-order earth spirits are the excellent 'food' of the three-legged crow.

"It's really unexpected, it's only been a few years since it entered the fourth order, it's just because I saw you fighting with Jin Taiji, and it began to touch the threshold of the bloodline fusion path. ”

On Zhuang Wudao's side, the sword spirit stood on the light cloud sword, and he couldn't stop admiring: "It is with you, it is estimated that it will only take another twenty years to digest your current Dao karma." Now that he has not yet melted the Dao, he can already be in the top ten on the outlier list. Twenty years later, I'm afraid that its strength is enough to be comparable to the top five generations of that day! I wonder if this little guy has mastered the method of 'boiling blood'?"

Mo Ling and Zhuang Wudao are connected to each other, and they are both destined for each other. Zhuang Wudao realized what the mysteries of heaven and earth, and Mo Ling was also able to perceive it. And what understanding Mo Ling can gain from the bloodline, Zhuang Wudao can also grasp it.

Before, Mo Ling's strength was not enough, so he couldn't comprehend the way of Zhuang Wudao. And twenty years ago, Zhuang Wudao was only familiar with the three ways of thunder and fire.

But now it is different, in the past 20 years, Zhuang Wudao has not only been used to 'measure the heavens by borrowing the law' and externalizing the body. On the way of 'merging', we have gone further, which also includes the method of 'life and death' in the sword of life and death. For Mo Ling, it is of great benefit.

And this bloodline fusion path is the opportunity for the demon beast to enter the sixth order. If you achieve the fusion of the blood god, you can enter the fifth order, and the blood fusion path is the threshold of the sixth order.

That Jin Taiji had already reached this point, and his achievements surpassed many sixth-order or even seventh-order demon beasts. It's only because of the limit of heaven that it can't be advanced.

In fact, like him, like Mu Yuanxuan and Jin Taiji, he is already far beyond the scope of Yuan Shen Cultivator and Fourth-Order Demon Cultivator. But Mo Ling can enter the fourth-order body for the first time, and his combat power is faintly capable of catching up, and the talent of the pure-blooded divine beast is strong, which can be seen from this.

"After all, it's the Divine Beast! Boiling Blood has already mastered it, but it has never been used. ”

Zhuang Wudao didn't care, when he formed a natal contract with Mo Ling, didn't he value the bloodline of the divine beast and be able to grow with him, and not become a burden to himself.

However, he was also keen, and there was a hint of strangeness in the sword spirit's tone.

"You seem strange? Pure-blooded beasts, shouldn't that be the case?"

"The fact is that the Light Cloud Sword has gone through several tribulations, millions of years, and has never encountered such a miracle. ”

Luo Qingyun shook his head, with a puzzled expression: "Mo Ling's vitality is condensed, and his cultivation is improved, which is quite normal. But in terms of this integration, there is something abnormal. The bloodline of the divine beast is not unpleasant, but the problem is that Mo Ling is too fast, or Mo Ling has another chance in the millions of years that he has been sleeping in the egg. Either the parents have left some means for their children. I guess its parents are probably also one of the many demon immortals who have fallen in the immortal tomb—"

As he said this, Mo Ling flew back from a distance with a cheerful expression, landed lightly on Zhuang Wudao's shoulder, and then collapsed lazily. The size of this little bird has not changed much, but Zhuang Wudao can sense the thought of 'eating up' from Mo Ling's thoughts.

Dumbfounded, Zhuang Wudao stopped the conversation about Mo Ling: "Inside the Demon Cave, there are all Yin Wind and Phantom Mirage, as well as Demon Evil, but in this Yang Cave, but it is completely the opposite, I estimate that the temperature in front will only get higher and higher, and I don't know when it will come to an end." ”

He was walking in a corridor with red on all sides. And the temperature around it was enough to instantly burn out any foundation monk who entered this place.

And the reason why those rocks have not melted is because after going through a hundred tempering, the material has been raised to the extreme by the flame power here.

It is said that the qiē here is the opposite of the Earth Demon Cave, but it is not just talking. Down from the entrance of the Huoyun Cave was an abyss full of molten lava, as deep as the Earth Demon Cave, hundreds of thousands of zhang.

Fortunately, Zhuang Wudao did not need to dive directly into this lava, and there were hundreds of miles around this lava deep lake, surrounded by a series of Yongdao.

Extending in all directions, spreading for thousands of miles, those forks and branches are enough to make people dizzy. It is a top-level secret technique like 'Chongming Guanshi Pupil', which is not very useful, and it is the same as when he was in the Earth Demon Cave, which was obstructed by a strange force, and Zhuang Wudao could only glimpse the stratum five hundred miles away at most.

Fortunately, Zhuang Wudao has those Yuhuo dzi given by Jin Taiji, and he does not have to go back and forth to explore, and the progress is extremely fast. At the end of 20,000 miles, it can also be compared with the 'Land of Chaos' in the Earth Demon Cave, and the context can be explored.

However, when he arrived here, even if Zhuang Wudao's Chongming Yang Divine Record had been cultivated to the fifth heaven, there would be a three-layer realm of absolute dust and solid mountains. With the fourth layer of the unbroken golden body, the body is also a little unbearable here.

That firepower was so strong that Zhuang Wudao had to use the 'Kun Yuan True Flame' as hard as he could, absorbing the surrounding Fire and Earth Element, and then transforming it into Shi Ming Jing Flame.

Then use the Shi Ming essence flame to turn into a fire butterfly, fly to the distance and explode, in this way, to reduce the high temperature around his body.

But this is not a one-and-done strategy, it is estimated that it will not be long before Zhuang Wudao has to use the twenty-four 'Yuhuo Dzi'.

The darker speculation in my heart is that the reason why Jin Taiji gave up halfway was because he had a treasure like Yuhuo Dzi in his hand, and he couldn't resist the blazing heat here, right?

Huo Kejin, Jin Taiji is the White Tiger of the West, and none of his magical powers can make it walk in the depths of this Huoyun Cave.

"Since it is a correspondence, it should be comparable to the Yin Demon Cave. ”

The sword spirit closed his eyes, as if sensing something: "I feel that the flames here seem to contain the power of immortals!"

"Immortal power?"

Zhuang Wudao was stunned, and his first reaction was disbelief. If it really contains immortal power, the power of immortals. Then at this moment, he has already been refined into slag by the flame power here!

"It's not really immortal, it's divergent. It's like the demonic blood in your hands, diluted a thousand times. And these immortal powers, no one can control them, and I deduce that they should be left over from millions of years ago. ”

Luo Qingyun explained, and when he opened his eyes, his eyes were full of essence: "Sword Master, do you still remember those words left by your Xuanxiao Patriarch. ”

He said that at the bottom of this Yin Demon Cave, there were probably two corpses of immortals and demons. ”

Zhuang Wudao was also slightly chilled in his heart, looking down. Chongming Guanshi Pupil looked through the five hundred miles of stone layers, and it was still difficult to see the bottom of the cave.

However, Zhuang Wudao had already faintly anticipated the next danger. The corpse of the immortal demon, even after death, will inevitably cause all kinds of visions, and even the entire power of heaven and earth will participate in it.

"I need to find a place to prepare—"

This is not that Zhuang Wudao is weak and timid, but that he must be fully prepared. There is a natural fourth-order Root Flame here, which is an excellent refining fire.

Zhuang Wudao had already collected some materials before, plus twenty-four 'Yuhuo Heavenly Beads', which was enough to refine twenty-four 'Yuhuo Heavenly Mirrors'.

With the Chongming Guanshi Pupil, he searched everywhere for a suitable place to practice weapons, and after a moment, Zhuang Wudao's heart moved again, and then his face was full of joy.

"So it's here!"

One dodged and fled, and after about five breaths, Zhuang Wudao had already appeared five hundred miles below, in another underground cave.

It is also an extremely wide space, 2,000 feet from north to south. And in the center, there is a pale golden spirit tree,

It looks similar to the jujube tree in the mortal world, but it is also plausible, and it looks like it is leafy, but on this big tree, only three fruits have been produced.

"It's actually the root of heaven and earth!"

Yun'er only saw it for the first time, and exclaimed: "It seems that the Sword Master's Sixth Heaven Bull Demon Yuan Hegemonic Body, as well as the Great Monument Wrestler, should be able to cultivate! Maybe you can also complete the fourth layer of the Death Absolute Dust Battle, so that you can not break the golden body and enter the fifth layer." ”

Zhuang Wudao's pupils were also dilated, and the excitement in his heart was almost unbearable.

The spiritual treasure in front of him was not a real fruit tree. Native gold is born, but soil is also the source of wood. And the so-called root of heaven and earth, that is, Xuanyi. It means that this place is the place where the power of heaven and earth gathers, and it is also the gate of Xuanqi. The power of heaven and earth merges here, so it can maintain strange things.

The branches and leaves of this 'tree' are actually stony, but they just look like trees. And those three fruits are not real fruits, but the gathering of the essence of the earth here.

It's a pity that there is no water here, and there is no water source for the most important water source of plants and trees, otherwise this 'spirit tree' that was born and raised by the earth will sooner or later change into a real tree and become one of the 'spiritual roots of heaven and earth'.

It is said that the 'Ten Innate Spiritual Roots' in the Heavenly Immortal Realm, the 'Nineteen Spiritual Roots of the Day After Tomorrow', were generated in this way.
