Chapter 583: The Collapsing Sky

His Divine Sense swept toward the four people around him, discovering they were still in a state of unconsciousness. Zhang Nuo flicked his robe sleeves, rolling out several rays of rosy light that wrapped Bi Yuyang, Chen Li, and the others within them. Then, the escape light on his body rose, halting their downward momentum!

The immense turbulence brought about by passing through the spatial tunnel was something even these four people at the Integration Late Stage could not fully withstand! If not for the fact that Zhang Nuo practiced Dharma-Body Dual Cultivation, he would likely be in the same state as them right now!

He glanced downward; it was likewise a pitch-black expanse. If they were to fall to the ground from this height, they would likely break their bones and tendons instantly, turning into a meat paste!

Just at this moment, Bi Yuyang was the first to wake up. The woman let out a cry of alarm, looking at the ground below, then looked at Zhang Nuo with an expression of astonishment and uncertainty. Immediately after, Chen Li, Du Hui, and the others also regained their senses.

After clarifying the situation, the four of them thanked Zhang Nuo profusely!

"It seems what we thought before was still a bit too simple! This Cross-Boundary Teleportation Array is only suitable for the constitution of demon beasts; for us human cultivators, it is still too strenuous!"

Bi Yuyang circulated the cultivation method throughout her body once, saying with lingering fear!

"It is fortunate that Fellow Daoist Zhang was here; otherwise, even if we had arrived in the Demon World, the consequences would likely have been unthinkable!"

Chen Li said, still shaken, though his gaze was fixed on the ground below. However, given their current altitude, his eyesight was still unable to see the scenery below clearly!

Zhang Nuo had remained silent, his brows locked tightly together. Seeing him like this, the four were all greatly puzzled.

"What is wrong, Fellow Daoist Zhang?"

Xu Ren asked suspiciously. Zhang Nuo's expression did not change; he merely extended a finger and pointed toward the high sky above! The four of them looked up simultaneously. Upon seeing this, they could not help but have their expressions change drastically, with gasps of astonishment following one after another!

They saw that the sky of the Demon World was a gray, hazy expanse, with almost no sunlight to be seen. Moreover, within the gray light, thunder-like roars were constantly erupting! That was not all; in some places, the sky had clearly collapsed inward, revealing a pitch-black void inside, from which unknown mysterious lights would occasionally fall!

"This... how could the Demon World become like this?"

Chen Li said in terror. Although this was his first time in the Demon World, he had learned some things about the Demon World through the classics in the Immortal Domain. While the specific environment could not be compared to the Immortal Domain, it should not be like this. It looked as though the entire Demon World was now not even as good as the 'Nine Lives Desert'!

"I was wondering why this Demon Beast Tide was so fierce; it turns out the Demon World truly cannot hold on for much longer!"

Xu Ren rubbed his bald head and said as if suddenly enlightened.

"It is all the fault of the great powers of the Immortal Domain back then for being too greedy. If they hadn't stolen the heavenly treasures of the Demon World back to the Immortal World, how could a war between realms like the Demon Beast Tide have occurred!"

Bi Yuyang said with an unpleasant expression.

"Fellow Daoist Bi, Zhang has not been in the Immortal Domain for long. I just do not know what exactly the great powers of the Immortal Domain stole from the Demon World back then to cause the Demon World to be in its current state?"

Zhang Nuo's question made Chen Li and the others deeply concerned as well. They had only heard that the heavenly treasures of the Demon World were transported back to the Immortal Domain, but no one knew what the specific items were!

The young woman brushed the dark hair from her forehead and said with her expression slightly softened:

"I suppose my ancestors of the Bi Family were involved in this matter, so I know a little bit about it! These matters are strictly forbidden from being spread outside the Immortal Domain Sixteen Chambers, but since the five of us have come to the Demon World, it is hard to say whether we can return alive. It is better to speak it out and clear everyone's doubts!"

The four of them listened quietly as Bi Yuyang narrated! A moment later, everyone's face revealed an expression of disdain!

It turned out that during the 'Ten Thousand Year Tribulation' war back then, the Immortal Domain dispatched four cultivators at the Great Accomplishment Stage. These four, in conjunction with Great Accomplishment Stage cultivators from numerous other realms, finally succeeded in sealing the 'Chaos Insect King'. However, because the power of this Insect King was too formidable, it was an especially dangerous existence regardless of which realm it was stored in!

Finally, after discussion, everyone decided to seal the 'Chaos Insect King' in the Underworld. Since the Underworld was extremely proficient in the way of the soul, they could achieve the goal of long-term sealing of the Insect King through soul-binding!

However, the 'Chaos Insect King' had previously broken through the boundary and arrived here in the Demon World. Transporting it to the Underworld would not be so simple. If any accident occurred in the spatial tunnel and the Insect King escaped again, it would not be something these people could subdue!

After much thought, among the Great Accomplishment Stage cultivators of several realms, there were three Array Masters. One must know that once one reaches the Great Accomplishment Stage and is also devoted to the study of arrays, the arrays they can create are certainly extraordinary! They decided to join forces to create a Cross-Boundary Teleportation Array that could directly connect the Demon World and the Underworld, and during the transmission process, no abnormalities would occur!

Although this idea was good, after the three Array Masters spent several years producing the blueprints for the Cross-Boundary Teleportation Array, these Great Accomplishment Stage cultivators all became distressed! The reason was none other than this!

This Cross-Boundary Teleportation Array was fine, but the Spirit Power required was an astronomical figure. Even if all the Spirit Stones in the entire Demon World were added together, it would likely not be enough to activate the teleportation array!

Driven by necessity, the Great Accomplishment cultivators of several realms began to set their sights on the Spirit Veins of the Demon World! The territory of the Demon World was also very vast, but within this continent, there was a Main Spirit Vein running from north to south. All the reproduction and cultivation of demon beasts relied on extracting Spirit Power from this vein!

Moving this Spirit Vein was equivalent to moving the foundation of the Demon World! When someone proposed this idea, it was immediately rejected by the great powers of the Demon World! Although the demon cultivators also wanted to send the 'Chaos Insect King' out of the Demon World, they would absolutely not do so at the cost of the Main Spirit Vein!

But now, the Spirit Power existing in the Demon World was simply insufficient to activate such a massive Cross-Boundary Teleportation Array, and for a time, everyone was deadlocked at this point!

After trying various methods, none were successful. Later on, several of the Ten Kings of the Underworld simply stopped paying attention to the matter. Transporting the 'Chaos Insect King' into the Underworld was also a very dangerous affair; even if they used 'Soul Chains' to perform a soul seal on the Insect King, there were still certain risks!

If the Insect King were to break the seal in the Underworld, it would be an unprecedented catastrophe for the entire realm! Seeing that the Underworld cultivators were about to renege, the cultivators from other realms immediately went to persuade the leaders of the Demon World at that time!

One must know that they had paid a heavy price to seal the 'Chaos Insect King' this time. If they missed this opportunity and left the Insect King in the Demon World, the consequences would be unthinkable!

Finally, the strong figures from several realms offered numerous benefits, which finally made the Demon World compromise! When the Cross-Boundary Teleportation Array connected to the Main Spirit Vein of the Demon World, the land of the Demon World shook as if it were about to collapse!

With the help of this array, the 'Chaos Insect King' was safely transported to the Underworld. However, what the demon cultivators never expected was that just as the Insect King was being transported to the Underworld, the Spiritual Qi of the Demon World's Main Spirit Vein was drained dry by some mysterious force at a very rapid speed!

When the entire transmission ended, the Main Spirit Vein of the Demon World was practically ruined, causing the Demon World to never recover from that point on! And according to the cultivators who originally designed this Cross-Boundary Teleportation Array, a single transmission would not consume much Spiritual Qi from the Main Spirit Vein!

But since the event had occurred, the demon cultivators naturally refused to let it go. Even with the compensation given by the various realms, it was absolutely impossible to make the Main Spirit Vein recover!

Later, the three cultivators who created the array, after checking every link, finally found some clues. It turned out that during the transmission process, the Spiritual Qi in the Demon World's Spirit Vein was inexplicably drawn into the Immortal Domain, causing the Spirit Power of the Immortal Domain to surge, instantly becoming a rare treasure land!

With the three Array Masters' proficiency in the way of arrays, they naturally would not think it was their own oversight! In subsequent investigations, they actually discovered that someone had tampered with the spatial tunnel through which the array light had to pass, though the traces were destroyed afterward.

However, the net of heaven is vast, and nothing escapes it. Based on just these few clues, the three cultivators tracked it to the Immortal Domain. From the suddenly surging Spiritual Qi in the Immortal Domain, they deduced that all of this was the work of the Immortal Domain!

When everything became clear, the demon cultivators hated the Immortal Domain to the bone. They did not expect the great powers of the Immortal Domain to be so shameless as to use such means to steal the power of the Demon World's Main Spirit Vein!

But for a time, the Demon World could not find evidence, so the Immortal Domain Sixteen Chambers flatly denied it! More than a thousand years later, the demon cultivators finally could not endure the exhausted Spirit Veins and launched the first Demon Beast Tide against the Immortal Domain!

But that time, the demon cultivators were acting on impulse and had no good planning, so it ended in failure a few hundred years later!

But for the second Demon Beast Tide more than ten thousand years later, the demon cultivators had made full preparations. Due to the complete exhaustion of the Main Spirit Vein, the Demon World would almost certainly not survive another thousand years. Before the Demon World was completely destroyed, the demon cultivators had to seize a piece of territory in the Immortal Domain to provide for the reproduction and survival of the demon cultivators!

This was the main reason for the Demon Beast Tide! Zhang Nuo looked up at the collapsing sky of the Demon World, feeling very uneasy in his heart. Human greed had caused huge losses to the Demon World, causing a once-prosperous realm to be on the verge of disappearing forever!

Bi Yuyang's ancestors had also participated in the theft of the Demon World's Main Spirit Vein Spiritual Qi, so she knew the details quite well. As this matter was treated as top-secret information of the Immortal Domain and was not allowed to be spread, not many cultivators in the Immortal Domain knew about it. Furthermore, as time passed, many cultivators failed to survive their Heavenly Tribulation and perished, and the matter was slowly forgotten by people!
