The defensive line fell

Inside the Underground Cave.

The Tiger Lord himself has arrived.

Standing atop the city wall, hundreds of feet high, this is a Small City. The entire Small City is a Grand Formation, protecting the Space Rift at its very center.

Originally, when the Human Race withdrew, this city was destroyed by Devil Beast, and the Demon Race took over and rebuilt it on the original site.

Tiger Lord gazed into the distance.

The whole world was pitch black, and not a single blade of grass grew.

That is the world where Devil Beast lives.

Or rather, this is the real Demon Realm!

The Dragon Demon Realm, and other regions suitable for life, are merely spaces influenced by the Demon Realm energy.

It is called Underground Cave because such passages only appear underground where Liaokong has been shattered.

Tiger Lord's expression was somewhat solemn.

Over the years, the Demonic Qi within the Dragon Demon Realm has grown increasingly dense, and the Demon Race and Demon Beast have been increasingly affected by it, becoming unusually prone to madness on the Full Moon Night.

They might easily escalate into a fight over something trivial.

The culprit was the Underground Cave Underground Cave. The Demonic Qi inside was so intense that even he felt slightly uncomfortable upon entering. Demon Race below the Void Heaven could not even stay in the Underground Cave's defenses for long.

Therefore, the city now mainly consists of Cultivator at the Void Heaven or above.

This change has caused some anxiety throughout the entire Dragon Demon Domain, as people are unsure whether the situation will continue to worsen.

Today, the Yin-Yang energy within the Underground Cave suddenly became more pronounced, clearly indicating that Yin-Yang Realm Devil Beast had arrived in the vicinity.

Tiger Lord's eyes gleamed with a ghostly light as he strained to see into the distance, but he couldn't find it at all. All he could see was an ever-growing number of ferocious-looking Devil Beast gathering. Most of them were asleep after they gathered, and when they occasionally opened their eyes, you could see that their eyes shone with a cold, blood-red light.

These Devil Beast varied in cultivation level, and those at the Heavenly Change Realm had already charged out wildly, or rather, were fighting each other. There were quite a few of them.

In the past, Devil Beast could "smell" life through Space Rift.

But over the years, such scenes have become increasingly rare, as a force has been restraining them.

Scattered Devil Beast are merely troublesome, but not necessarily a threat. However, if they are integrated into a single force, the situation becomes entirely different!

Suddenly, Space Rift appeared behind them, and the Demon Ape King, clad in Battle Armor, emerged.

He stood shoulder to shoulder with Tiger Lord, looking into the distance, his brow furrowed, and said, "They really are endless; there are so many again."

In recent days, they naturally haven't just waited passively; they've attacked the gathered Devil Beast multiple times, but to no avail.

No one knows what is hidden in this Heaven and Earth that has given birth to so many Devil Beast, and as the Demonic Qi grows stronger, their growth rate seems to be accelerating.

The Iron Eater Tribe at least needs to consume various kinds of spiritual bamboo to increase their cultivation, but these Devil Beast seem to only need to lie down and sleep to become powerful in the Demonic Qi.

"Yes, now that a Yin-Yang Realm has appeared, no one knows if more will appear in the future." Tiger Lord's expression was serious.

"Can't you find it?" Demon Ape King.

"It's hidden too well, its Demonic Qi is too dense, and it's extremely cunning, completely unlike a mindless demonic Devil Beast. Only once did the Demon Emperor come here and track it down, but it didn't fight us at all, instead using Devil Beast to block our way before escaping into the depths of the Underground Cave. It's growing extremely fast. Judging from its aura, it wasn't my match before, but now, I'm no longer confident."

"If this continues, it will become a major problem sooner or later!" Demon Ape King.

Tiger Lord said helplessly, "Everyone knows this, but there's nothing we can do. The Underground Cave is too big, and even we dare not stay in the depths for long, otherwise our Divine Soul will be invaded."

"Perhaps the one up the mountain... well, I'm afraid he won't care about these things at all."

Tiger Lord remained silent for a moment, then turned and asked, "When will you achieve Yin-Yang?"

"It'll be soon, but we still need to wait for the right Opportunity..."

Just then, the two Demon King suddenly turned their heads to look into the depths of the Underground Cave.

What was that sound?

Their expressions changed slightly. The voice was extremely faint, as if someone were whispering in their ear. It was indistinct, but when it reached their ears, they felt their Divine Soul tremble slightly, as if an instinctive fear from the depths of their souls was rising.

The next moment, the sleeping Devil Beast in the distance awoke one after another, opened their blood-red eyes, and headed towards the city.

The earth trembled violently, Demonic Qi surged, and countless Devil Creature surged and flew, covering the sky and obscuring the view.

Tiger Lord roared, "Charge!"

The entire city glowed with a ghostly light, and countless Great Demon activated their Yao Energy to deploy a protective array.

Moments later, the Devil Beast attacked.

Tiger Lord, Demon Ape King, and several other Great Demon Three Tribulations of Heavenly Change stood atop the city wall, revealing their true forms and engaging the Devil Beast in battle.

Vast numbers of Devil Beast corpses fell below the city walls, piling up like mountains.

But these Devil Beast were all fearless and undaunted.

Suddenly, a Great Demon Three Tribulations of Heavenly Change let out a miserable scream and fell off the wall.

Tiger Lord turned around and saw a figure disappear into the distance.

"Human Race? The Yin-Yang Realm in the Underground Cave is Human Race?"

The figure then vanished into the vast, endless Devil Beast, as if the Protection Grand Formation had no effect on him whatsoever.

"Watch out! The Yin-Yang Realm is here! It's Human Race!"

Tiger Lord spread his Divine Sense, intending to find him. He could vaguely sense that the person was nearby, but he didn't know what kind of concealment method the person used, hiding among the densely packed Devil Beast, and he couldn't find his exact location at all.

The Tiger Lord revealed his tiger form and roared to the sky.

Within a radius of dozens of miles, countless Devil Beast fell to the ground, even those at the Three Heavenly Change Realms Devil Beast were momentarily stunned.

His gaze then quickly locked onto a spot, where Dao Body vanished into thin Liaokong as a phantom.

Then, the Devil Beast from further away swarmed forward again.

A moment later, another Great Demon, who had undergone Three Tribulations of Heavenly Change, was severely injured.

This time, Tiger Lord caught a clue and swung his hand to grab it away.

The man gave a sinister smile, his entire body turning into mist, and Tiger Lord's claw landed on Liaokong air.

The Tiger Lord roared again, causing the mist to churn and forcing a figure to emerge from it. However, the person raised his hand and drew a line with his finger, unleashing an invisible Sword Qi that forced the Tiger Lord to retreat. He then quickly retreated and hid among the Devil Beast again.

A moment later, the Demon Ape King roared in fury, a wound several feet long appeared on its chest, and the figure had already retreated when it swung its club in retaliation.

However, the wounds on his body failed to heal for a long time, and the Demonic Qi on the Sword Qi continued to erode his Yao Qi.

As time passed, the Great Demon guarding the city suffered increasingly severe injuries, and Tiger Lord alone could no longer protect everyone. Several nodes in the city's Array Formation were also damaged.

Tiger Lord immediately shouted, "Get out of the Underground Cave!"

He roared, and his body suddenly grew to a size of about a mile. He stood in front of all the Devil Beast, blocking them behind him. All the Great Demon retreated, and the Tiger Lord went out last. The Devil Beast beasts, fearless of death, followed closely behind.

In an instant, Demonic Qi also burst through the Space Rift and soared into the sky...
