Inside the open secret door, a long-lasting rancid smell came to his face, time did not allow Mu Mu to think about it at all, the viscous liquid behind him seemed to be sensitive, and it rushed towards the secret door very quickly, fusing with other liquids in the process, and constantly growing itself into a stream in an instant.

Inside the secret door was a long and narrow staircase, neatly arranged, and when you looked down, there was darkness ahead, and you didn't know where it would lead.

Mu Mu didn't have time to think, he quickly sprinted down, the bluestone stairs looked very steep, but it was nothing to him in the rapid sprint, and he crossed the steps like a dragonfly, rushing down.

The light in front of me gradually turned from dim to dark, and the sound of the wind in the darkness was "whirring" in the ears, in addition to the sound of the wind, there was also a strange sound coming from behind him.

The black frenzy chased along the narrow staircase, making a strange sound of "snort" along the way, and Mu Mu, who was in a hurry to rush down, also noticed that something was wrong, but he was helpless.

The strange sound is less than ten meters away from him behind him, and now even if he stops for a while, he will be caught up by the strange sound.

Don't think about it, only rush in the dark.

"Plop" There was a muffled sound, a sound that sounded very dull, Mu Mu stopped, trembling and stopped, as if he had hit something in the dark.

"―Ahh

The sound of "snorting" behind him was agitated, rapidly shortening the distance between each other.

"Yueyao, you, where are you?" Mu Mu shouted quickly, with a feeling of pain in his voice.

"Brother, I'm okay here" Yue Yao shouted, a faint red light appeared in the center of her eyebrows, and the flame runes beating in the center of her eyebrows emitted a faint light.

Mu Mu picked up Yue Yao and looked around in the faint light, he was standing on a closed staircase, and a solid wall was erected in front of him.

The sound of "snorting" appeared behind him, Mu Mu glanced at the rushing black frenzy, and immediately ran away.

Under the dim fluorescence, Mu Mu finally knew why there was a strange sound of "snort", and the stairs under his feet were full of weathered wreckage, weapons and armor were covered with thick dust, some looked like humans and the remains of other races.

Looking at these corpses lying everywhere, one can imagine that a long time ago, there was a horrific massacre here.

Mu Mu didn't have time to take a closer look at who these people were, nor did he observe why these people died, the black frenzy behind him rolled down in the stairwell, and where he passed, the wreckage on the ground turned into dust in the sound of "snort".

Mu Mu's feet continued to accelerate, and there was a faint fluorescent fluorescent guide from Yueyao's eyebrows in his arms, so naturally there would be no more tragedy of 'hitting the south wall', and along the narrow bluestone staircase, he threw off the surging black wave behind him, and rushed all the way down.

I don't know how many steps I have descended, I don't know where I am, I just run all the way along the steps, and I don't have time to think about the rest.

Suddenly, the bottom of the originally dark staircase lit up, and a wave of heat rushed towards the face at the same time as the bright light appeared, followed by shaking.

The entire bluestone staircase shook, and the corpses on both sides of the stairs shook up in the dust, and then they were engulfed by the black frenzy behind them.

Mu Mu rushed to the light in one breath, raised his hand to block the light that suddenly appeared, and was stunned when he got used to it.

The earth shook, shaking in the continuous eruption of the pillars of flames, and one after another towering pillars slammed into the suspended chains, and the blazing heat scattered with the fall of the pillars of fire, followed by pillars of fire that were even more violent than the previous ones, rising.

In the center of the pillar of fire, on top of a huge altar, there was a coffin of unknown material that was not made of gold or wood, and the coffin was carved with many esoteric runes, and the runes were like tiny tadpoles, densely carved around the coffin.

The top cover of the coffin is inlaid with a ring buckle, and the iron chain with the thickness of an arm is connected to the buckle, and the other end of the giant iron chain is connected to the rock wall, which is carved with strange patterns, such as human figures, birds and beasts, and the sun, moon and stars.

Mu Mu hurriedly swept a glance at the vast space, three black lines immediately surged out of his brows, and his eyes stared straight at the mountain wall, a hole between the mountain walls that didn't look very big, and two figures were lying on the edge of the hole, staring at themselves.

In a short moment, the black tide rushed into the belly of the mountain.

"Mu Mu" Zi Yan shouted happily.

"Yueyao," Shui Lingzi also shouted happily.

Mu Mu quickly rushed to the bottom of the cave entrance and shouted loudly: "Stay up there and don't move." As soon as he finished shouting, he immediately turned into a remnant and galloped away, dodging the attack of the black frenzy in the belly of the mountain.

Zi Yan stayed at the entrance of the cave, and the surprise of seeing Mu Mu disappear in an instant, and a deep fear crossed her eyes.

The black frenzy slapped against the rock wall, and rolled towards Mu Mu at great speed, staring at the black wave that was as black as ink surging and agitating, and where it passed, the color of the surface became darker, and fine cracks could be seen everywhere.

Mu Mu's extremely tired legs started a life-and-death chase in the empty mountainside, and the black frenzy behind him exerted all his strength, his body sometimes gathered, sometimes scattered, and he opened and closed as he wanted, constantly volleying Mu Mu.

In the center of the mountain, the pillar of fire in the magma pool was surging, the churning vibration, the fine marks left by the black frenzy, the vibration continued to expand, and the fine lines along the edge of the magma pool became more and more, and gradually wisps of crimson solution seeped out of the magma pool along the small cracks, slowly expanding.

Mu Mu's actions became more and more difficult, not only to avoid the black frenzy chasing after him, but also to pay attention to the crimson magma flowing everywhere, coupled with the thick smoke and blazing temperature everywhere, the sweat on his body was like rain, and the speed under his feet slowed down, and he couldn't get up.

The crimson liquid that overflowed from the magma pool was all around, and the rising pillars of flame became more and more intense, and the chains hanging above Zhen's head swayed, making a golden clash.

Mu Mu has been forced into a desperate situation, surrounded by crimson magma, there is no place to stay, and the black frenzy is gradually eroding the altar and besieging Mu Mu.

Mu Mu gritted his teeth and shouted, "When... Light back... Trace"

The weak voice shouted the spell of the soul mark, there was no soul mark in the center of the eyebrows, a weak feeling of prostration crawled all over the body, the black liquid in front of him gradually devoured the ground under his feet, Mu Mu quickly retreated, and fell into a desperate situation.

In the continuous retreat, he was blocked by something behind him, and when he turned his head to see that the coffin was blocking behind him, he could only climb on the coffin to avoid the erosion of the black solution.

The mournful shouts of "Mu Mu" and "Yue Yao" broke out, but to no avail, the black frenzy did not stop but rushed towards the coffin, and the rolling waves slapped against the four walls of the coffin.

The runes on the four walls of the "snort" were dissolving, constantly dissolving in corrosion, and the traces turned into dust and dissipated, climbing towards the top of the coffin in an instant.

The pillar of fire in the magma pool rose noisily, and the hanging iron chain could not withstand the continuous eruption of the pillar of fire, and a small hole was cracked in it, and a crisp sound of "Karma" was heard.

The black solution crawled all over the coffin, the space under Mu Mu's feet disappeared in an instant, the black liquid climbed up along Mu Mu's heels, Mu Mu suddenly closed his eyes, his eyes closed, his hands were spread out, his head was raised high, and the moment he was raised, his heels stood up gently, his toes were a little to the ground, and the whole person was miraculously suspended in the air.

The black liquid suddenly rippled under Mu Mu's feet, and after the ripples spread, it quickly converged, and the center position of the moment of convergence was raised by one point, and then the liquid around it quickly converged, and the center point continued to rise, instantly catching up with the height of Mu Mu's ascension.

A drop of viscous liquid instantly stained the sole of his shoe, but in this instant, the liquid spread out and climbed up on the soles of Mu Mu's feet.

"-Ah!" A terrible scream, Mu Mu exclaimed in pain, at this moment of crisis, he threw Yue Yao out of his hand, and Yue Yao screamed in the air: "-No." ”

Yueyao's scream couldn't save Mu Mu, Mu Mu fell heavily from the air on the coffin, and the turbulent coffin lid shook for a while, and his whole body was instantly covered by a viscous liquid.

"No, don't" Yue Yao shouted bitterly, rolled over from the ground, and frantically pounced on the black solution recklessly.

"No" Zi Yan was shocked and inexplicable, jumping down from more than ten meters in the air, there was only Mu Mu in her eyes, and nothing else.

Shui Lingzi stretched out his hand to grab Zi Yan, but everything happened too quickly and too suddenly, he didn't catch anything, his body was too hard, and he fell down with a dip.

The moment Yue Yao rushed towards the black liquid, she suddenly flew backwards, and a tyrannical soul pressure exploded instantly.

The magma pool turned over the river and the sea, wave after wave of pillars of flame gushed out, the violent vibration was like an earthquake roaring, the blazing temperature rose instantly, and the air went crazy in the temperature.

The raging wind rolled up the pillar of flames and smashed mercilessly towards the chains above his head, and in the powerful churning of the flame tornado, several chains were torn apart by the powerful flame storm.

The moment the chain broke, a strange pattern on the top of the mountain's belly emitted a dazzling brilliance, and under the brilliance, a pillar of light instantly fell from the sky.
