The tremors on the Tunnel World's side also alarmed those on the Gray Land's side. With the intervention of that mysterious figure, the rifts between the Tunnel World and the Gray Land grew larger, and many new rifts appeared. The dark canopy that shielded the Tunnel World was also shattered by that mysterious figure.

As a result, a large number of beings from the Gray Land poured in at once.

They all cheered, sang, and praised... feeling that an unprecedentedly beautiful era had arrived!

When has the entire Tunnel World ever been so open?

The newly added gigantic rifts, in the eyes of countless beings from the Gray Land, seem like the most beautiful paths in the world, like roads to Eden!

However, unlike those ordinary beings from the Gray Land, the big figures within the Gray Land could no longer remain idle.

For example, the Evil Venerable Bigfoot who once wanted to befriend Chu Mo, the Old Immortal of the Red Serpent Clan who had enmity with Chu Mo and Meng Na, the One-eyed Great Venerable of the One-eyed Clan, as well as the Three-leaf Heavenly Venerable and the Blood River Great Venerable - all these Supreme level ancient ancestor existences were now alarmed.

They had felt a slight premonition back when Supreme Wuji and Immeasurable Buddha left the Tunnel World. But the methods of those two supreme beings were too astute, directly concealing all commotions. When Chu Mo was refining those thousands of universes, they felt a strange premonition as well. Yet, they still couldn't find the source.

But things should not repeat thrice!

Especially this time, it wasn't just a mere premonition. On the entire ground connecting the Tunnel World and Gray Land, countless gigantic rifts appeared!

This was something that had never happened before! For ten thousand ages, it was a first!

Hence, the rulers, the Supreme ancient ancestors from the Gray Land, all exited their seclusion. They were even quicker than those muddle-headed beings of the Gray Land, and in an instant, through the rifts with almost no law suppression, they arrived in the Tunnel World.

The next moment, they were completely dumbfounded.

The tattered dark canopy, the disintegrating Tunnel World.

Where their divine sense could reach, there was desolation.

The life force was dim, the essence energy was in decline.

This was simply a vast abandoned world!

"How... how is this possible?" Evil Venerable Bigfoot's eyes were filled with endless shock. How long has it been since the last invasion of Gray Land beings? How could it have become like this?

Although it hadn't been ravaged to the point of being a wasteland, in the eyes of any cultivator, this world was a completely abandoned one!

The Old Immortal of the Red Serpent was also in a daze. It wasn't its first time coming to the Tunnel World. In fact, countless ages ago, its avatar had been here.

But back then, the Tunnel World in its eyes was simply the most beautiful place in the world!

If it had been possible, it would have brought the Red Serpent Clan to migrate into this world long ago. But unfortunately, the ancient clans in the Tunnel World, as well as those annoying cultivators, regarded them as mortal enemies. They absolutely wouldn't allow their territory to be infringed upon in the slightest.

The Old Immortal of the Red Serpent had even calculated in its mind that one day, when reaching a higher realm, it would lead the whole clan to break in.

But what it never dreamed of was that this day had come quite quickly. But the problem is, this was no longer the world it desired.

"What's the situation? Has the Tunnel World... suffered a catastrophe?" Three-leaf Heavenly Venerable, dressed in a Taoist robe, was a true member of the Human Clan, appearing very elegant. But at this moment, his eyes were full of confusion.

The Blood River Great Venerable over there murmured, "I'm afraid it isn't just the Tunnel World suffering a catastrophe, but all of us living beings are about to encounter a catastrophe!"

Evil Venerable Bigfoot suddenly felt its essence energy and spirit droop, murmuring, "Yes, I'm afraid we really are about to face a disaster. It's obvious that someone in the Tunnel World knew about this situation in advance. Then they almost swept away all the resources and life forms. Did you feel it? The life force in the Tunnel World has vanished!"

The other four Supreme ancient ancestors nodded. At their realm and level, their sensing abilities were all extremely keen. If it weren't for that dark canopy overhead, they might have perceived what was happening through the rift long ago.

"Damn it!" The One-eyed Great Venerable stomped its foot in anger, pounding the mountains and rivers for billions of miles into pieces!

It shattered the land directly with that stomp!

Without the crystal core, not only was the life force in this world declining, even the power of laws had become significantly weakened.

Under normal circumstances, the One-eyed Great Venerable's stomp wouldn't have caused such destructive power. Because it didn't even use much force. It was just venting.

The other four ancient ancestors of the Gray Land exchanged glances, and all saw that trace of endless fear in each other's eyes.

No matter their previous relationships, whether enemies or friends, everyone felt a boundless desolation at this moment.

This feeling was utterly terrible, the worst in their long lifetimes.

The feeling of fate being out of their control, the feeling of being abandoned for the first time... rose in their hearts.

And at this moment, a large number of beings from the Gray Land swarmed into this tattered world like locusts. They roared with excitement, howled with excitement, bellowed with excitement... in short, they were very excited!

Initially, even some of the great ancestral beings were excited. However, they quickly realized something was amiss. This was nothing like the Tunnel World they had imagined!

Five Supreme Gray Ancestral Beings sighed in unison and without hesitation left the Tunnel World and returned to the Gray Land. They needed to prepare for the unknown future!

No matter how thick the shell, they wanted to give it a try because no one wanted to be trapped here!

The first to seek out his most trusted disciple, Xie Xie, was the Bigfoot Evil Venerable. At this moment, Xie Xie also understood what had happened. Upon seeing the Bigfoot Evil Venerable, Xie Xie gave a wry smile and said the first words: "Master, we missed the best opportunity back then!"

The Bigfoot Evil Venerable looked at Xie Xie: "Are you talking about that Chu Mo?"

Xie Xie nodded: "The last time we invaded from the Gray Land, I wanted to rebuild relations with Chu Mo. But at that time, Chu Mo was too notorious. Even the Mane God General had his head chopped off by him, and the elite warriors of the Mane Clan were completely annihilated."

The Bigfoot Evil Venerable nodded: "I know about this, the Mane Clan from the Gray Land declined because of this and was swallowed by General Wulong."

Xie Xie nodded: "Actually, I should have met with him back then. I believe Chu Mo would have remembered the ties of the past. At least, in this incident, he might have given us a chance. Alas..."

"You mean Chu Mo is involved this time?" The Bigfoot Evil Venerable frowned slightly: "He is merely an ancestral realm cultivator, does he have such capabilities?"

"Ancestral realm cultivator?" Xie Xie shook his head: "I suspect he already stepped into the Supreme Realm. Even if he is still in the ancestral realm, back then, he was under the protection of the supreme Wuji and the Immeasurable Buddha. Otherwise, how could he sweep through the thirteen ancient clans of the Tunnel?"

Sighing, Xie Xie continued: "We were all shortsighted at that time, thinking we could seize substantial benefits amidst the Tunnel's chaos. Indeed... we did gain benefits. We acquired an unprecedented amount of cultivation resources, enough to squander for ten thousand years. But now... what use are they?"

The Bigfoot Evil Venerable took a deep breath, his eyes showing a wise light. He gently shook his head and said: "It's okay, we still have a retreat strategy."

"A retreat strategy?" Xie Xie looked at his master incredulously.

The Bigfoot Evil Venerable nodded: "However, the place is quite unstable; it's a long tunnel. I've always suspected it to be a blood vessel of an ancient god, but many parts are dried up and hard to pass. Going through that tunnel will surely require a price."

Xie Xie looked at the Bigfoot Evil Venerable: "Master, has our great world truly reached a dead end?"

The Bigfoot Evil Venerable nodded: "Yes, we have truly reached the end of the road!"

Soon, the Three-leaf Heavenly Venerable, One-eyed Great Venerable, Blood River Great Venerable, and Red Serpent Old Immortal, these four Supreme Ancestors from the Gray Land, arrived together.

No matter how many grudges there were in the past, at this moment, they all had to be set aside. Because now it was a matter of life and death survival. Everyone understood if they did not unite, none of them would escape!

Years later, almost all the Gray Land beings had rushed into the Tunnel World. Henceforth, for the first time in history, the Tunnel World was completely occupied by Gray Land beings.

Although the Tunnel World had shown signs of decline, and over ninety percent of resources had been taken, comparatively, it was still countless times better than the harsh conditions of the Gray Land. So, a large number of Gray Land beings were very satisfied. They occupied this world.

In the meantime, led by the Bigfoot Evil Venerable, five Gray Land Supreme Ancestors gathered tens of thousands of ancestral realm Gray Land beings and over a million Great Saint Realm Gray Land beings, heading towards a road full of the unknown and dangers.

When they finally found this road after enduring innumerable hardships, the five Supreme Gray Land Ancestors were dumbfounded.

For the road was nearly sealed shut!

The situation was far graver than they had imagined countless times over!

Initially, the five Supreme Gray Land Ancestors thought that with a certain price, they could break through. But now, even they were unsure.

Xie Xie couldn't help but look to the sky and sigh deeply, then looked resentfully at General Wulong over there, thinking if only you hadn't captured those Human Clan women back then, I wouldn't have clashed with Chu Mo, and perhaps we wouldn't face today's situation.

Over there, General Wulong was puzzled; even now, it knew nothing.

So, facing the resentful Xie Xie, General Wulong wore an innocent expression.
