The sky was stained with blood and the smell was pungent.

The magma in the deep pit with a radius of 5,000 zhang tumbled, forming a vacuum, which was suffocating. It was as if the air was still.

A large mouth spewing fire suddenly appeared in mid-air, the upper and lower jaws were raised, and the black hole in the middle was thirty zhang square, and the suction power was like the original wind tunnel, which could swallow everything, and even the magma was sucked by more than one-third.

Mu Zifeng's thin body was like a gray leaf, and it was instantly sucked into the mouth of the fire demonic beast. It closed its mouth suddenly, and it seemed to be very sweet.

"Hahaha! Rao is you treacherous like a ghost, and you still haven't drunk the emperor's footwashing water?"

The fire beast burped in satisfaction and let out a long breath of red gas.

"Really?"

Suddenly, a joking voice was heard in mid-air.

"Ahh

The fire monster screamed, although he did not transform into a shape, but he also turned his mind, and suddenly turned around, and found that except for his head, half of his body had been cracked and turned into nothingness.

It was Mu Zifeng who displayed the Cloud Demon Cold Flame, since you are a hot attribute demon beast, then the cold attribute Cloud Demon Cold Flame is his nemesis, and without noticing, the fire demon beast was really fooled.

"Plop!" With a bang, the fire beast's head more than twenty meters in size suddenly fell into the magma, and the splashed magma was eighty zhang high.

"Die!" How big a wave can a fire monster that has no body make?!

A black-green sword shadow the size of two hundred zhang slashed towards the head of the fire demonic beast.

"Poof", there is no doubt that the huge head was split in half at once, because this time Mu Zifeng hit the Cloud Demon Cold Flame in the flying sword to kill him, this time no matter how the fire demon beast struggled and reunited, it was useless.

A red beast pill with a diameter of ten meters also floated on the magma, and as soon as Mu Zifeng's spiritual power moved, the beast pill was put into his storage bag by him.

This fire demon beast's talent and supernatural powers are really two, if it weren't for the fact that Mu Zifeng had already reached the peak combat power of the first-order demon emperor, if he was replaced by someone else, I am afraid that he would not dare to take risks easily.

Mu Zifeng smiled slightly, his spiritual power radiated out, and when he looked in one direction, a fierce man plunged into the hot magma.

Because he sensed a sign of formation fluctuation from under the magma, as if something was sealed underneath.

"Could it be the fireball?"

As soon as you enter the magma, the temperature below is not as high as it seems.

Mu Zifeng's defensive formation was like a balloon in the world, enveloping him entirely, no matter how hot it was outside, but he couldn't feel it at all inside, even the clothes on his body were cold, and there was no trace of burning.

The bottom of the magma was black, without any light, if it weren't for Mu Zifeng's superior spiritual power, he wouldn't have been able to give back anything at all.

It wasn't until about a thousand meters down that the magma suddenly churned, and I am afraid that this is the vent of the magma.

But the gossip map in his mind has not reacted at all until now.

According to the direction of the spiritual power feedback formation, Mu Zifeng walked in the magma for half an hour, and suddenly a huge cave appeared in front of him. The cave is more than 500 meters high, with strange rocks and interlaced teeth.

The lava was like a small river, bubbling from one side of the cave. The whole cave is full of clouds, and the shadows are too dark to see things clearly.

Mu Zifeng stood up from the magma and jumped onto a boulder. I found that the fluctuations of that formation were even stronger.

"Could it be that there is a relic here?!"

His spiritual power radiated out suddenly, and he found that there was a pitch-black gate about a hundred miles ahead, and the fluctuations of that formation were transmitted from the direction of that gate.

As soon as his mind moved, the whole person appeared five hundred meters in front of the gate.

The direct gate is very simple, divided into two, with a height of hundreds of zhang, and each gate is thirty zhang wide. The gate is printed with some ancient cloud patterns, and some unknown words are also engraved, which looks like a talisman seal, and a flickering light is emitting from the talisman, which makes people feel very depressed and palpitating.

Mu Zifeng took a few steps forward, feeling the power emanating from the formation on the gate, even if the powerhouse of the Demon Venerable rank came, I am afraid that he would not be able to bear it.

The pressure is like a hammer that keeps hitting the depths of a person's heart, as if to make a person surrender from the bottom of his heart.

A breath of antiquity also diffuses from there.

In front of this gate, within a range of 100 meters, there are white bones everywhere, there are demon beasts, but more of them are monks, which look dense and terrifying.

Among them, there are more than a dozen white bones, the bones are crystal clear, and at first glance, they are left by a powerhouse at the level of the Demon Venerable.

At first glance, seeing these accumulated white bones, Mu Zifeng couldn't help frowning slightly, "It seems that for ten thousand years, not only myself, but also some other strong people have also entered here." ”

Judging from these bones, there must be other roads leading to here besides the magma pool, otherwise with the cultivation of the fire demonic beast in the first half year, these people would have already made his meal.

Mu Zifeng straightened his spine and walked forward step by step towards the pressure of the formation.

Out of the corner of his eye, he saw that there were still some weapons on the ground, including magic knives and magic swords, all of which were old and rusty, and when he touched his foot, he immediately turned into ashes.

The same goes for those storage bags around them.

Only three or two could be used, and they were all picked up by Mu Zifeng and put them in his storage bag. Although the things in it were useless to him, for the entire Mu Zi Sect, it was better than nothing.

"Woohoo!"

There was still a hundred meters away from the gate, and suddenly, the runes on the pitch-black gate turned, and beams of light similar to lasers in the world flew towards Mu Zifeng.

Each beam of light was no less than a Demon Venerable rank powerhouse striking with all his might.

For a while, in the heavens and on the ground, the beam of light seemed to form a cage, and it was like a meat grinder, and when it was caught off guard, even if the fifth-order Great Demon Venerable came, there was a danger of falling.

"Little Doyle!"

Mu Zifeng smiled slightly, a crystal clear yellow wall suddenly appeared in front of him, the beam hit the defensive wall formed by the earth beads, making a sizzling sound, the ten-meter-thick defensive wall did not even penetrate half a meter, and the beam turned invisible.

Now that his star body had been tempered to the level of Sainthood Great Perfection, even if he walked over like this, those beams of light would not cause him any harm.

It was too late, it was too fast, Mu Zifeng's right hand was raised, and a bright light emanated from his hand, rushing straight towards a round ball above the hundred-zhang high pitch-black gate.

"Click!"

The pitch-black ball, which was a meter in diameter, made a terrifying sound, and immediately turned into powder, and the runes on the gate immediately stopped moving as if they had been immobilized, and even the light above it dimmed.

This small killing array, in front of Mu Zifeng, the formation master, was a little too childish, and it was broken by him in a gesture.

Although the formation was broken, the gate did not appear to be open, and it stood there quietly.

"Open it for me!"

A black-green light flickered, and a sword light the size of thousands of zhang blasted towards the gate.

"Boom!"

The door exploded as if it had been attacked by a * in the world, and even the entire space shook like an earthquake.

Rubble and smoke filled.

An even more violent heat wave suddenly rushed out, like a volcanic eruption, and all the rubble on the ground, including the bones, where the heat wave passed, turned into powder.

Mu Zifeng was like a big bird, the moment the heat wave rushed out, he had already flown into the air, and his spiritual power shot into it through the hole in the gate, and everything inside was reflected in his mind.

It was a small space, or a small world, more appropriate, that space was not large, and the radius was only about a hundred miles, but in addition to the smooth stone walls, there was magma everywhere underground, like a huge furnace, and this gate with a formation was like the exit of the furnace, and now the exit was broken, and the magma inside rolled and flowed out.

"Huh!" The gossip map in Mu Zifeng's mind suddenly worked, and bursts of longing calls also emanated from the gossip map, and the scene was the same as when he met the wind beads.

"Could it be that there are beads of fire under the lava?"

Mu Zifeng's heart was happy, he no longer hesitated, flew up like a big bird, and suddenly got into the hole of the gate, and according to the direction of the gossip map, he plunged into the rolling magma with a bang.

The bottom of the magma was extremely hot, and the magma was bubbling and bubbling, like a melting pot in a steelmaking mill in the world, not to mention people, even if it was fine iron, it could melt in an instant.

The periphery of Mu Zifeng's body was wrapped in thirty defensive formations, but within a single stick of incense, more than half of those thirty formations were corroded.

His forehead was also slightly sweaty, and his body was even more roasted, if he hadn't carried the Human Emperor Formula, he would have turned into a cloud of mist in minutes.

"This is too, why is the environment so bad wherever every heaven and earth treasure is?"

Mu Zifeng also felt a thick egg pain, the last time he absorbed Lei Zhu, he had already experienced a lot of hardships, but compared to the current suffering, it was really a small thing.

There is no way, the cultivation of monks is to fight for their lives with the heavens, how can there always be such a good thing that goes smoothly?!

"Hey, who are you?"

Suddenly, a childish child's voice came into Mu Zifeng's mind.
