What appeared before Mu Chen's eyes was an extremely vast and spacious underground world. As of now, countless lumps of light were floating within this spacious underground world. These lumps of light were extremely dazzling, while astonishing Spiritual Energy fluctuations radiated from them.
"These are all Spiritual Lights?"
Mu Chen's eyes were filled with shock as he looked at the tens of thousands of lumps of light. From the Spiritual Energy contained within those lumps of light, these were at least Spiritual Knight level Spiritual Lights. And now, such a large amount of Spiritual Lights had actually gathered in this place.
This scene was truly spectacular.
Mu Chen's gaze followed along the direction of the bright and resplendent Spiritual Lights. In the most central region of this underground world, he saw the most dazzling lumps of light. That lumps of light were somewhat gorgeous, and within it, a crystal approximately a foot in size could be faintly seen floating.
That crystal was sparkling and translucent, and there seemed to be a viscous liquid flowing within it. The bright and dim rays of light were akin to a beating heart, while possessing some kind of mysterious life force.
Following the sparkling rays of light from the crystal, Spiritual Energy rays of light gushed out from within the countless Spiritual Lights. In the end, they endlessly poured into the crystal that was a foot in size, causing its rays of light to become increasingly bright.
An indescribable Spiritual Energy fluctuation rippled out like water waves, causing Mu Chen's heart to beat rapidly.
"So the Spiritual Knights of this extremely dangerous region have all turned into these Spiritual Lights!"
Mu Chen finally understood why he was unable to see even a single Spiritual Knight after entering this place. So it turned out that they had all turned into Spiritual Lights. These Spiritual Lights were obviously providing Spiritual Energy to the crystal.
"Could it be that this place was created by the Spiritual King?" Mu Chen was somewhat astonished.
From the looks of the situation underground, it was obviously not man-made. In other words, this was all caused by the Spiritual King.
He never imagined that this kind of existence without any intelligence would actually know how to create an underground world.
Perhaps this was due to their own abilities, but it was sufficient to show the mysteries contained within this world.
"No wonder the strength of the Spiritual King doesn't seem to be especially strong." Mu Chen's eyes shone as he looked at the bright and resplendent Spiritual Crystal.
The Spirit Qi inside surged to a horrifying degree.
According to Mu Chen's conjecture, the scene in front of him should be to help the Spirit King pass through the weak birth stage. As long as the Spirit King absorbed this Spirit Crystal that had absorbed the Spiritual Power of numerous Spirit Generals, the big fellow outside would be able to truly become a Spirit King.
Mu Chen's eyes flickered as his figure shot out. A few breaths later.
He passed through the layers of spiritual light.
He approached the dazzling Spirit Crystal.
It was only when he got closer that he was able to see what was inside the Spirit Crystal.
The viscous spiritual liquid flowed, vaguely forming an illusory light.
It was incomparably profound.
Mu Chen did not immediately take action towards the Spirit Crystal. Instead, he swept his gaze downwards. In the next moment, he saw a few purple-coloured clumps of light closest to the Spirit Crystal. Within those clumps of light, there was also a purple-coloured Spirit Crystal. However, it was far from being as shocking as the one before him. However, the Spiritual Energy ripples gushing out from it were still much more powerful than the Spiritual Lights that Mu Chen and the rest had previously obtained.
"It's a Heavenly Transformation Stage Late Phase Spirit Knight!"
A pleasantly surprised expression flashed within Mu Chen's eyes. Shortly after, without the slightest bit of hesitation, he sent a fist rumbling out. Erratic Spiritual Energy bombarded one of the purple-coloured clumps of light. As the clumps of light shattered, the purple-coloured Spirit Crystal that was hidden within flew out, before being grabbed by Mu Chen.
When the purple-coloured Spirit Crystal landed in Mu Chen's hand, extremely astonishing pure Spiritual Energy instantly radiated out. Mu Chen circulated his Spiritual Energy and slightly absorbed it, feeling the exhausted Spiritual Energy within his body gradually recovering.
"It's truly worthy of being the Spiritual Light formed by a Heavenly Transformation Stage Spirit Knight!"
Mu Chen laughed heartily. Without the slightest bit of politeness, he took action. In a short span of a dozen breaths, he completely shattered the dozens of purple-coloured clumps of light in the vicinity, before seizing those purple-coloured Spirit Crystals into his hands.
Those dozens of purple-coloured Spirit Crystals were at least equivalent to several tens of thousands of ordinary Spiritual Weapons.
Humm!
Humm! However, as Mu Chen seized those dozens of purple-coloured Spirit Crystals into his hands, the gigantic and gorgeous Spirit Crystal seemed to have sensed something. Instantly, humming and vibrating sounds rang out. Spiritual Energy gushed out, transforming into a Spiritual Energy wave that violently swept towards Mu Chen.
"You want to cause harm to me with Spiritual Energy that doesn't possess any offensive properties?"
Seeing this, a smile appeared on Mu Chen's face. With a wave of his sleeve, Spiritual Energy blazing with black flames gushed out, easily blocking the incoming Spiritual Energy wave. In the next instant, his eyes blazed as he stared at the Spirit Crystal. This is a genuine treasure!
With a clench of his hand, a longsword that sparkled with brilliance appeared in a flash. Pitch-black Spiritual Energy enveloped it as black flames rose. Taking a step forward, he appeared directly above the Spirit Crystal. The Spiritual Energy within his body gushed out as a hundred-foot-long pitch-black sword light gushed out from the tip of the sword, before violently chopping down towards the Spirit Crystal.
Clang!
A metallic sound rang out as crystal fragments fluttered in the air. Intense pain radiated from Mu Chen's palm as the web between his thumb and forefinger split apart. The toughness of the Spirit Crystal had exceeded his imagination.
Creak!
However, this full powered strike of his still had some effect. A crack appeared on the corner of the Spirit Crystal, before a fist-sized Spirit Crystal fragment fell out, which was caught by Mu Chen.
When Mu Chen caught the Spirit Crystal fragment, he instantly felt his arm sink, as if he was holding a thousand catty heavy rock.
Astonishment flashed within Mu Chen's eyes. He knew that this was due to the Spiritual Energy being condensed to a terrifying degree. The Spiritual Energy contained within the Spirit Crystal before his eyes was too frightening.
However, this caused Mu Chen's gaze to become increasingly scorching. However, he didn't know that at the instant he chopped down the Spirit Crystal fragment, the Spirit King, who was entangled with Xu Huang, Zhao Qingshan and the rest, suddenly roared towards the sky in fury.
Roar!
The roar transformed into a Spiritual Energy storm that swept out, sending Xu Huang and the rest, who were caught unprepared, flying away.
Stabilizing their bodies not far away, they looked in bewilderment at the Spirit King, who had suddenly gone berserk. At this moment, the latter did not pay any attention to them. Clenching his giant hands tightly, his fists carried frightening power as they violently smashed against the ground beneath his feet.
Bang!
The ground seemed to have experienced an earthquake at this moment, as gigantic fissures extended out from the ground beneath the Spirit King's feet.
In the next instant, it explosively rushed towards the ground at an astonishing speed.
It was also at this moment that Mu Chen, who was underground, also sensed something. Immediately, his expression changed, and he did not dare to stay any longer.
His figure explosively retreated.
Bang!
The giant boulder abruptly fell down, as sunlight tore through the ground and shone down. The ground where Mu Chen was previously standing was immediately blasted apart by a frightening power, leaving behind a bottomless black hole.
This was the Spirit King's crazed all-out attack.
It was extremely frightening.
"What's that?!"
When the underground world was exposed under the sunlight, it was immediately sensed by Xu Huang and the rest in the sky. Instantly, they cried out in alarm, dumbfoundedly looking at the countless Spiritual Lights that flickered with dazzling brilliance.
However, very quickly, their gazes converged on the gigantic, sparkling and translucent Spirit Crystal that was emitting a frightening Spiritual Aura. Their gazes immediately became sluggish, as the Spiritual Aura on its surface caused their throats to involuntarily roll for a moment.
"There's someone there!"
Some people had sharp eyes.
They had actually seen Mu Chen, who was preparing to quietly leave.
Instantly, they lost their voices in shock.
Swish!
Everyone's gazes instantly shifted over.
Then, they firmly stared at Mu Chen's figure. When they clearly saw who that figure was, their expressions slightly froze.
"Why is Mu Chen there?" The corner of Mu Fengyang's mouth twitched.
He hastily turned his head to look at the gigantic pit from before, where the Black Tower was.
It had actually suddenly disappeared. Below the Black Tower was a bottomless black hole.
Seeing that he had been discovered, Mu Chen no longer concealed himself. Shooting out from the ground, he smiled towards everyone and said, "Just now, I was mysteriously blasted underground, and discovered a little strange thing."
Everyone looked at him suspiciously. Obviously, they did not believe his words. However, at this moment, where would they have the time to argue with him? Each and every one of them had blazing gazes looking at the countless dazzling Spiritual Lights below. There were so many of them. If they were able to snatch a few, it would be enough to return with a rewarding harvest.
"Roar!"
However, just as their gazes became increasingly greedy, the Spirit King roared. With a huge suction from its mouth, the countless Spiritual Lights directly converged together, and were completely swallowed into its body.
At the same time, the gigantic Spirit Crystal also flew up. Upon seeing this, Mu Chen's gaze flashed, and he explosively shot out. Soon after, a palm slammed onto the Spirit Crystal. This palm of his did not destroy the Spirit Crystal. A black flame quietly shot into it, while his figure explosively retreated.
As the Spirit Crystal shot up, it was also swallowed into the Spirit King's body.
In a short span of a few breaths, the underground world had become completely empty.
Everyone was dumbfounded.
Upon seeing this scene, Mu Chen's heart madly thumped. If the Spirit King completely absorbed all of these, wouldn't it directly pass through its birth period?
Once its strength explosively increased, how could they resist it with their current lineup?
His scalp turned numb as he raised his head, only to see the dazzling Spirit King. At this moment, it was like a scorching sun, its radiance causing people to not dare to look straight at it. Furthermore, its gigantic body had once again started to expand.
Powerful Spiritual Energy radiated out, as if a storm had been stirred up in its surroundings.
"Wang Tong, quickly leave!"
With a fierce roar, Mu Chen instantly turned around, and explosively shot out.
Upon seeing this, Wang Tong and the other two slightly hesitated, before clenching their teeth and hurriedly following. Not far away, Luo Li, An Ran and the rest immediately shot out, and closely followed behind.
As for Zhao Qingshan, Xu Huang and the rest, they were somewhat unwilling, as their expressions fluctuated indeterminately.
Roar!
While they were hesitating, the Spirit King gave a roar. A gigantic thousand metre Spiritual Energy wave surged out, violently smashing against their bodies. Mouthfuls of fresh blood spurted out from the numerous figures, while their faces turned pale.
"Go!"
The expressions of Zhao Qingshan and the rest finally changed drastically. Looking at the gigantic Spirit King that had already expanded to over two hundred metres, they clenched their teeth, and explosively retreated.
At this moment, everyone retreated in a sorry state, no longer daring to have the slightest bit of thoughts towards the Spirit King.
While they were retreating, the Spirit King had also stopped its expansion. Furiously roaring, its eyes, which were filled with brilliance, locked onto Mu Chen, who was rapidly shooting out from afar.
It was able to sense that the missing piece of its Spirit Crystal was on the latter's body. Only by obtaining that piece of Spirit Crystal, would it be able to thoroughly pass through its weakest birth period!
Roar!
As it furiously roared, it took steps that shook the earth and mountains as it crazily chased after Wang Tong.
