"I can escape from here."

Baiyu frowned; entering underground wasn't a simple task, especially in the demon territory.

Even if disguised.

If you go underground alone, it will surely attract a lot of attention.

At this moment, Baiyu tried to remain inactive to avoid creating any abnormal situation that might lead to unnecessary trouble.

Digging underground without knowing its depth felt almost like courting death.

Eulai seemed to have realized the difficulty, and started contemplating other methods.

Just as the two were deeply pondering.

Suddenly.

A earth-shattering explosion sounded from the Demon King's Palace in Demon City not far away, followed by a pillar of lightning rising into the sky.

The palace built at Demon City's highest point began to collapse.

Massive stone fragments fell from above, hitting the streets of Demon City with loud crashes.

A group of demon people exploded into chaos.

"Aba Aba!"

"Aba Aba Aba!"

Intense shouting from the demons echoed all around.

Though Baiyu couldn't understand, he could guess what they were yelling about.

After the initial shouts.

Teams of demon soldiers started emerging from all over the streets, attempting to maintain order.

However.

This maintenance was futile.

For many demons, the Demon King's palace was a sacred holy place.

Even though the Demon King was often absent from Demon City, the location was inviolable, seen as a symbol of the Demon King's might.

Now it had collapsed out of nowhere.

For ordinary demons, it was akin to a collapse of belief, causing an unimaginable uproar.

"Aba! Aba Aba!"

"Ababa!"

Demon soldiers and other demons started confronting each other.

Baiyu still couldn't understand a word.

But it was evident.

Apparently, ordinary tribesmen wanted to investigate, but were stopped by the soldiers.

The tension was intensifying.

As time advanced.

The pillar of lightning above the Demon King's Palace not only didn't disappear but expanded, causing more sections of stones to collapse.

By now, the entire Demon City was in turmoil.

Evidently, everyone had realized the gravity of the situation.

Currently Lord Demon King was inside the palace, he would undoubtedly take action if under attack.

However.

The collapse continued.

The Demon King hadn't sent out any messages.

This unease made all demons in the city converge on the palace, making the soldiers' maintaining order increasingly difficult.

Baiyu blended in, stirring up disorder.

In such chaos, no one noticed him, let alone exposed his identity.

"It seems Yao Shuimei has started a fight inside, the rescue plan has hit a snag. I must muddle the situation." Baiyu thought to himself.

If only he spoke the demon language, he could definitely incite the demons to take action against the soldiers.

Now.

Baiyu could only cause turmoil, forcefully colliding against the demon soldiers' defense alongside the demon crowd.

As the situation escalated.

The entire Demon City was surging forward.

The first person broke through the soldiers' defense line.

Meanwhile, the demon commanders and esteemed elders failed to control the situation.

Everyone was desperate to find out what was happening inside the palace and why the Demon King hadn't acted.

This hadn't happened in hundreds of years.

If something happened to Lord Demon King.

The demons would completely lose their say in the Demon Alliance.

Which was why people were so frenzied.

With one person entering the palace, others followed suit shouting "Aba Aba", emotions tense and stirring like chanting a slogan.

Seizing this chaotic moment.

Baiyu continued exchanging methods with Eulai, upon understanding the way to enter underground, he vanished amidst the chaos.

...

"Old man, are you sure it's here?"

Moments later.

Amidst the city's chaos, Baiyu arrived at a sewage entrance in the demon city.

Eulai confirmed in his mind: "It's here, you go down first. Below is the demon's underground system.

I remember Demon City was built on top of an Ancient Ruin.

The underground sewer system.

Should connect with underground fresh water, there's a path leading to where I am."

Eulai was trapped in a Rune Prison deep underground.

Due to its very secrecy and powerful Array covers, few in Demon City knew about it.

Those who did.

Knew a great demon from the Era of Darkness was imprisoned here.

They never approached recklessly, nor dared open the prison.

Even the Fourth Celestial Demon King only reinforced the Rune Array trapping Eulai, did nothing else.

Soon, Baiyu climbed down the sewage ladder into the underground system of Demon City.

Contrary to expectations of filth and stench.

Upon descending, Baiyu understood firsthand what ancient technology meant.

According to Eulai, Demon City is built on the Ancient Ruins, with the underground system incorporating the Ancient Ruin's leftovers.

Before him.

He stood at a crossroads of underground pipes, all directions leading to pathways constructed with white metal.

At intervals.

Above these metal pipes were embedded special glowing gems akin to mythical Luminous Beads.

These lights illuminated the pipes brightly.

Baiyu touched the walls, felt a texture more perfect than the A-Level alloys produced by Villiduo Factory.

He pressed with his Blood Qi, leaving no trace on the metallic pipes.

"Kid, stop dawdling, you're right above my northern position, take that path to the left!"

Eulai's voice came through in his mind.

Baiyu glanced at several passages tall enough for two people, determined the direction, chose one and proceeded swiftly.

The passage was very long.

Due to limited time and uncertainty of the situation above, Baiyu moved rapidly.

Even at full speed he spent ten minutes reaching the first turn mentioned by Eulai.

Then.

He altered direction, continued advancing deeper into the pipes.

Repeating this process mimicked labyrinthine maneuvering, he seemed to finally reach the end of the pipes.

Ahead stood a metallic gate.

"Baiyu, remember what I'm about to tell you, once you pass through this gate, there'll be an underground water pool.

This pool connects to an underground dark river.

The area I'm trapped in lies beneath this dark river.

It's something I slowly discovered over the years using Spirituality, there should be no issue but you must heed the presence of large life forms I detected during my investigation, possibly subterranean Exotic Beasts exist.

Also, thanks for everything."

Vigilance spiked in Baiyu's heart.

The metallic gate wasn't difficult to open, it held only a useless lock that Baiyu split apart with a slash from his Moon Blade.

After splitting it open.

The surroundings suddenly transformed.

From metal pipes into stone walls, accompanied by constant dripping of water droplets.

This was a stalactite cave.

Water dripped down through stone layers, emitting a rhythmic dripping sound.

Before him flowed the rushing underground dark river.

The surroundings were pitch-black, apart from some glowing spore organisms, there were no light sources.

Luckily, Baiyu was prepared.

He directly activated the Forbidden Armament equipped with lighting tools, sufficient for navigating such a dark environment.

"Large life forms..."

Baiyu trekked a few steps finding the swift underground dark river, advancing along the bank without encountering life forms' traces.

Perhaps they were in the river.

But he would never jump in.

"Roar!"

As he steadily approached Eulai's location, a piercing beast roar reverberated, accompanied by a fetid breeze.

Baiyu staggered from the gust.

Soon, two enormous glowing red eyes emerged in the darkness...
