Sneak all the way down.

At this point, after passing through the protective array and using the Earth Escape Secret Technique to go deep into the mountain body of Tomb Flame Mountain, Su Wang found that in the depths of the mountain body of Tomb Flame Mountain, there was no cave.

Tsukasa Flame Mountain is a high mountain with dense forests, and there are also strange river cliffs, and the deeper you go into the mountains, the more powerful the surrounding ice and cold become.

And unlike outside the mountains, in the depths of the mountains, some inconspicuous mountains and mountain streams, grass, trees, flowers and stones, as well as potholes on the ground, etc., will erupt from time to time without warning, and the cold air is biting.

Su Wangneng concluded that if he ventured into the Tomb Flame Mountain, just with these strange dark green flames, cultivators below the Demon Pill Stage would be unable to move an inch, and the possibility of being frozen by these dark green flames and then incinerated was extremely great.

It's just that despite this, Su Wang still felt a little strange, because until Su Wang sneaked deep into the depths of the Tomb Flame Mountain, he didn't encounter any obstacles, not even a single demonic beast.

The forbidden place of the Immortal Flame Gate, its protection could be so lax?

But at this moment, Su Wang, who had no time to think about anything else, sneaked quickly in the depths of the Tomb Flame Mountain, saying that there was no cave, because there were many bifurcated passages and many stone chambers and caves in the depths of the earth, etc., obviously, these could never be naturally formed.

As Su Wang continued to sneak deeper, in the passage deep underground, Su Wang finally encountered some vicious and hideous looking demonic beasts, most of which were demonic pythons and demonic insects, and each demonic beast was emitting or swallowing cold flames on its body or in its mouth at all times.

These demonic beasts, most of them were cultivators in the psychic period, and they didn't notice Su Wang, who flew quickly past them, and Su Wang sneaked all the way like this, and so far he saw that there was a large sea of fire in front of the passage.

The flames of the sea of fire are no longer dark green, but dark green with black and purple, and the cold power it exudes has increased nearly a hundred times compared to the dark green flames, and these flames are extremely weird, as if they have spirituality, constantly jumping and changing, or turning into a flower of flames, or transforming into a crow of flames.

The cold of the flames, even Su Wang, who was still standing thousands of feet away, actually felt the cold and piercing, and had to run the Cold Soul Ghost Mystery Gong to feel that it was okay.

In the Mixed Ritual Ring, Xiao Yi had already taken Ji Xuedan, and the Meat Venerable in the Zhongyuan Palace, not long ago, used his Stealing Divine Power to help Su Wang pass through the protective array, and then fell asleep again.

In the moment before falling asleep, the Meat Venerable still remembered it, saying that the next time he woke up, Su Wang must find a delicious spiritual energy treasure for the Meat Venerable to devour.

There is black and purple in the dark green, and the flame transforms into a flower and a crow?

Isn't this exactly what Bao Zhi said, the bone-eroding flame that Ochre Bai needs to use when refining the Soul Demon Flame?

Su Wang ventured into Tsukasa Flame Mountain, the most important thing was to obtain two things, one was the bone-eroding flame in front of him, and the other was the venom of the eight-legged demon toad.

Thousands of feet away, a sea of fire composed of bone-eroding flames seemed to be easy to obtain.

It's just that Su Wang stopped his body, his hands flew and pinched, and the spiritual power in his body was running, and Su Wang was about to cast the Dou Zhuan Star Shifting Mystery Method, extracting the bone-eroding dark flame from the air.

At this moment, more than a thousand demonic lights with cold flames appeared out of thin air without warning, like more than a thousand flame demon knives, shining with fire and magic light at the same time, covering the entire wide passage, aiming at Su Wangqi and slashing in unison!

"Boom!"

The Flame Demon Knife slashed into the ground or wall of the passage, and it actually made a huge roar, and within the passage, in an instant, it seemed to become a flame passage, and the cold and piercing flames were everywhere.

"Annihilation!"

A cold gulp.

In an instant, countless sword lights, sword qi, and sword shadows, like the flame magic knives that appeared out of thin air, suddenly gushed out, and quickly met the dense flame demon knives around them, and the stirring wind swept towards the surrounding cold flames.

"Boom, boom!"

There was another huge tremor, but although the sound was huge, the passage where Su Wang was located did not move at all, and even the sand and stone did not stir up half a grain, so far, Su Wang still didn't know where to go, and there were also formations around this passage, but Su Wang had never found it.

After a while, the sword light, sword qi, sword shadow, and flame demon sword all quickly dissipated, and where the sea of fire was just now, in mid-air, Su Wang's figure appeared.

In the blink of an eye, Su Wang not only performed the Sword Attack of Extermination, but also crossed thousands of zhang and left the passage, but entered the sea of fire, but this was not that Su Wang was willing to do this, but that he had to do so.

"Bang!"

A huge flame demon knife of dozens of zhang quickly slashed through the air, but it slashed on the ground, and in an instant, the flame demon knife dissipated, sparks flew everywhere, and immediately turned into the surrounding bone-eroding dark flame again.

And Su Wang, at the moment when he just revealed his figure, flashed rapidly in mid-air, and he could avoid the slash of the Flame Demon Knife, and in mid-air, Su Wang's expression was solemn, and his gaze, spiritual sense, and corpse dog ghost were all rapidly scanning around.

The sea of bone-eroding flames is as wide as a radius of 10,000 zhang, and the stone chamber deep in the ground where the sea of fire is located is as high as 1,000 zhang, and it is a radius of 100 miles.

"Hmph, the reaction is quick, and the speed of the body is also good, but I didn't expect that the lowly monks of the Northern Wu Holy Continent actually have some ability. A cold, deep, disdainful snort rang out.

Su Wang's face remained unchanged, but he was suddenly shocked in his heart, because until this cold snort sounded, whether it was spiritual consciousness or the ghost of the corpse dog, Su Wang didn't notice at all that there was anyone around.

As soon as the cold snort fell, in front of Su Wang, more than 3,000 zhang away, the flames of the sea of fire suddenly rolled, and then quickly divided, revealing a figure who was meditating on his knees on a circular high platform in the depths of the sea of fire.

The figure was in the sea of fire, even on his body, face and head, there were heavy flames burning, but the figure was peaceful, and the cold and piercing bone-eroding flames around him seemed to be afraid and surrendered to the figure.

The figure is tall, with a bronze complexion, crazy hair like a faint green flame, a large and square face, thick and scattered thick eyebrows, dark and deep eyes, an eagle nose and a lion's mouth, but the breath is hidden but not dispersed, Su Wang can't even perceive what kind of cultivation the figure is.

Although the figure was just sitting there cross-legged, the whole person seemed to be like a mountain, like an abyss, and invisibly, exuding the domineering spirit of a king in all directions.

At this point, there is no need to ask more, Su Wang has already guessed that the figure in front of him must be the master of the Stygian Flame Gate, the Demon King of the Stygian Flame, and the Ochre Cypress!
