What appeared in Mu Chen's eyes was an extremely vast underground empty world, and now, in this empty underground world, there were countless light clusters floating, these light clusters were extremely dazzling, and there were amazing spiritual power fluctuations emitting from them.

"These... It's all aura?"

Mu Chen's eyes looked at the thousands of light clusters in shock, judging from the spiritual power contained in those light clusters, these were at least the spiritual lights of the spirit general level, and now, such a number of spiritual lights actually gathered here.

That scene was truly spectacular.

Mu Chen's gaze kept looking along the brilliant spiritual light, and then in the most central part of this underground world, he saw the most dazzling light cluster, which was a little gorgeous, and a spar about the size of a zhang was faintly visible.

The spar was crystal clear, as if there was a viscous liquid flowing in it, a bright and dark light, like a beating heart, with some kind of magical vitality.

And with the flickering of the spar's light, among the countless spiritual lights, there was also a rainbow of spiritual power gushing out, and finally it was continuously poured into the spar of a few feet in size, making its light brighter and brighter.

An indescribable fluctuation of spiritual power, rippling like water waves, made Mu Chen's heart beat rapidly.

"It turns out that the spirit generals in this extremely dangerous area have all turned into these spiritual lights..."

Mu Chen finally suddenly realized, why after entering here, he couldn't even see a spirit general, it turned out that they were all turned into spiritual light, and these spiritual lights were obviously providing spiritual power for the spar.

"Could it be that the Spirit King made it here?" Mu Chen was a little surprised, looking at the situation in the underground, it was obviously not man-made, that is to say, this was all made by the Spirit King, but I didn't expect that this kind of existence without wisdom actually knew how to build the underground world.

Perhaps this is due to their instinct. But it is enough to explain the magic contained in this heaven and earth.

"No wonder the strength of that Spirit King doesn't seem to be particularly strong..."Mu Chen's eyes burned as he looked at the brilliant spirit crystal, and the aura in it surged to a terrifying level.

According to Mu Chen's speculation, I am afraid that there will be a scene in front of him. It should be to help the Spirit King get through the weak birth period, as long as the Spirit King absorbs this spirit crystal that has absorbed the spiritual power of many spirit generals, then the big guy outside can truly become the Spirit King.

Mu Chen's eyes flashed slightly, and his body immediately swept out. After a few breaths, he crossed the heavy spiritual light and approached the brilliant spiritual crystal, and when he got closer, he could see that in the spiritual crystal, the viscous spiritual liquid flowed, faintly as if forming an illusory light and shadow, which was extremely mysterious.

Mu Chen didn't shoot directly at the spirit crystal, but swept his gaze downward. Then he saw that in the position closest to the spirit crystal, there were some purple light clusters, and inside those light clusters, there was also a purple spirit crystal, but it was far less shocking than the one in front of him, but the spiritual power fluctuations that gushed out of it were still much stronger than the spiritual lights that Mu Chen had obtained before.

"It's a spirit general in the late stage of the Heaven Transformation Realm..."

A look of surprise flashed in Mu Chen's eyes, and he didn't hesitate at all. Directly punched out, and the furious spiritual power bombarded a purple light cluster, and the light cluster shattered, and the purple spirit crystal hidden in it also flew out. Then he was grabbed by Mu Chen.

The purple spirit crystal fell into Mu Chen's hand, and suddenly an astonishing amount of pure spiritual power emanated, and Mu Chen's spiritual power was slightly absorbed, and he felt that the spiritual power consumed in his body was gradually restored.

"It's really worthy of the aura that the Heavenly Realm Spirit will transform!"

Mu Chen laughed out loud, not polite at all, understanding and shooting. In just a few breaths, he smashed all the dozens of purple light clusters nearby, and then snatched those purple spirit crystals in his hand.

These dozens of purple spirit crystals are at least worth tens of thousands of ordinary spirit soldiers.

Buzzing!

However, as Mu Chen snatched these dozens of purple spirit crystals into his hands, the huge gorgeous spirit crystals seemed to have sensed something, and suddenly buzzed and vibrate, and the spiritual power sprayed thinly, and it turned into a wave of spiritual power and swept away towards Mu Chen.

"You have no offensive spiritual power and want to hurt me?"

Seeing this, Mu Chen smiled, his sleeve robe waved, and the spiritual power burning with black flames gushed out, and it was easy to resist the waves of spiritual power, and then his eyes looked at the spirit crystal the size of a few feet, this is the real treasure!

He held the palm of his hand, a long sword flashed out with a flash, covered by dark spiritual power, black flames rose, he stepped out, directly appeared above the spirit crystal, the spiritual power in his body surged, and a huge black sword spurted out from the tip of the sword, and then slashed down fiercely at the spirit crystal.

Clang!

The sound of gold and iron resounded, crystal chips flew, Mu Chen's palm came from a sharp pain, the tiger's mouth was cracked, and the hardness of this spirit crystal was beyond his imagination.

Chirping!

However, his full sword still had some effect, only to see a crack open in the corner of the spirit crystal, and then a fragment of the spirit crystal about the size of a fist fell down and was caught by Mu Chen.

When Mu Chen caught the spirit crystal fragment, he suddenly felt his arm sink, as if he was holding a thousand pounds of stone.

A look of surprise flashed in Mu Chen's eyes, he knew that this was because of the weight of the aura condensed to a terrifying level, and the spiritual power contained in the spirit crystal in front of him was too terrifying.

However, this also made De Muchen's eyes more and more hot, but he didn't know that at the moment when he chopped off the spirit crystal fragments, on the ground, the spirit king who was entangled with Xu Huang and Zhao Qingshan suddenly roared angrily.

Roar!

The roar formed a storm of spiritual power, swept away, and directly shook the unprepared Xu Huang and them away.

They stabilized their bodies not far away, looking at the Spirit King who suddenly went crazy with a suspicious expression, and the latter ignored them at this time, directly clenched their giant hands, and then their fists carried terrifying power and slammed into the ground under their feet.

Bang!

This land, as if there was an earthquake at this time, huge cracks spread from the ground under the feet of the Spirit King, and then rushed towards the ground at an astonishing speed.

And at this time, Mu Chen, who was under the ground, was also aware of it, and immediately his complexion changed, and he didn't dare to stay any longer, and his body retreated violently.

Rumble!

The boulder fell suddenly, and the sunlight tore through the ground and shone down, and the ground where Mu Chen had stood before was immediately blasted through by a terrifying force, leaving a bottomless black hole.

This Spirit King's crazy full force blow was extremely terrifying.

"What's that?!"

The underground world was exposed to the sun, and it was immediately noticed by Xu Huang in the sky, and they all immediately exclaimed, staring at the countless spiritual lights that flashed with dazzling light.

But soon, their eyes were condensed on the huge spirit crystal that exuded a terrifying aura and was crystal clear throughout, and the eyes immediately froze, and the aura on it made their throats roll uncontrollably.

"Someone's there!"

Someone had sharp eyes, and when he saw Mu Chen, who was about to leave quietly, he was immediately shocked.

Swish!

All eyes shifted away in an instant, and then stared at Mu Chen's figure, and when they saw who the figure was, their expressions were even more sluggish.

"Mu Chen... Why is he there?" The corners of Mu Fengyang's mouth twitched, and he hurriedly turned his head to look at the huge pit before, where the black tower disappeared abruptly, and under the black tower, there was a bottomless black hole.

Seeing that he was discovered, Mu Chen no longer hid, swept out of the ground, smiled at everyone, and said, "I was inexplicably blasted into the ground just now, and I found something strange. ”

Everyone looked at him suspiciously, obviously a little unconvinced by this, but at this time, how could they have time to talk to him about this, one by one, their eyes were blazing and looking at the countless dazzling spiritual lights below, so much, if you can grab some, it will be enough to return with a full load.

"Roar!"

However, just when their eyes became more and more greedy, the Spirit King roared, and it sucked in with its big mouth, only to see that the countless spiritual lights were directly gathered together and swallowed by it all into its body.

At the same time, the huge spirit crystal also flew up, Mu Chen saw this, his eyes flashed, and he swept out, and then slapped a palm on the spirit crystal, his palm, did not destroy the spirit crystal, a black flame, quietly swept in, and at the same time his body retreated.

And the spirit crystal swept up, and it was also swallowed into the body by the spirit king.

In just a few breaths, the underworld became empty.

The crowd was sluggish.

When Mu Chen saw this scene, his heart was beating wildly, the Spirit King had absorbed all of these, didn't he have to go through the birth period directly? Once its strength skyrocketed, with their lineup, how could it resist?

He raised his head with a numb scalp, only to see the already dazzling Spirit King, at this time it was like a scorching sun, the light made people dare not look directly, and its huge body began to climb again.

Waves of powerful spiritual power emanated, as if they had caused a storm around them.

"Wang Tong, let's go!"

Mu Chen shouted loudly, turned around in an instant, and swept out.

Seeing this, Wang Tong and the three of them hesitated slightly, then gritted their teeth and hurriedly followed, and Luo Li, who was not far away, and An Ran and them also immediately swept up and followed.

And Zhao Qingshan, Xu Huang and others were a little unwilling, and their faces changed uncertainly.

Roar!

Between their hesitations, the Spirit King roared, and a huge wave of spiritual power rolled out, slamming into their bodies, and many figures spurted out mouthfuls of blood, their faces pale.

"Let's go!"

Zhao Qingshan's complexion finally changed drastically, and he glanced at the huge Spirit King who had climbed to more than two hundred zhang with some palpitations, gritted his teeth, and retreated.

Everyone retreated in embarrassment at this time, and they didn't dare to pay the slightest attention to the Spirit King.

As they retreated, the Spirit King also stopped climbing, roaring angrily, its eyes full of light, locking on the dust that swept out in the distance.

It can perceive that the piece of its spirit crystal is missing, and in the latter's body, only by obtaining that piece of spirit crystal can it completely survive the weakest birth period!

Roar!

In an angry roar, it took steps to shake the ground and mountains, and chased away frantically. (To be continued.) )
