The next moment, their faces became extremely grave!!!

Because, on the level five monster outside, there was an even more powerful force gathering.

A storm was forming behind it, sweeping in all directions...

Behind the level five monster, there stood nine figures hovering in the air, equally poised to strike, exuding a terrifyingly formidable aura.

These were nine level four monsters!

"Roar!"

With a roar, ten super monsters charged towards the Black Iron Castle together!

At this moment, the storm swept through.

It was as if countless thunders fell from the sky, the rampant energy almost tearing the entire space apart!

"It’s over!"

"Hold on!"

Inside the safe house, the trial-takers’ faces were pale, desperately activating the defensive power of the Black Iron Castle.

Boom!

Amidst the intense fluctuations and endless explosions, the defensive shield of the Black Iron

Castle seemed to be on the verge of collapse.

Fortunately, it barely held up in the end.

But then, countless monsters attacked again.

At this moment, the Black Iron Castle was like a small boat in the ocean, at any moment it could be overturned!

...

"We can’t hold on for long, there are too many monsters, and the gap in strength is too great!"

A level four trial-taker’s face was pale.

To support the defense of the Black Iron Castle, he had expended too much of his strength.

That level five monster was not simple, possessing some kind of ability to affect the mind.

Its roar affected most of the trial-takers’ minds.

At least, in the short term, these trial-takers could not join the battle.

Without their strength, it was extremely difficult to sustain the defensive shield of the Black Iron Castle.

"What should we do? Just the few of us, I’m afraid we can’t hold on for long, are we really going to die?"

Looking around, many trial-takers in the Black Iron Castle showed a look of despair.

Many more trial-takers had a dazed expression, their consciousness sluggish...

...However, at this moment.

"A cold, indifferent voice suddenly echoed throughout the Black Iron Castle.

"A level five monster? Where did these monsters come from? Daring to attack the Black Iron Castle? Very well, all of you go to die!"

This cold voice, like a clap of thunder, exploded in the ears of every trial-taker.

For a moment, several level four trial-takers shuddered, their spirits instantly revived.

And those trial-takers who were in a dazed state, upon hearing this thunderous voice, also snapped out of their stupor!

Their faces were filled with astonishment.

At the same time, their eyes lit up with excitement.

Accompanying this cold snort, terrifying waves of energy also emanated from the depths of the Black Iron Castle.

This was an energy fluctuation they were all too familiar with!

...

In an instant, from the depths of the Black Iron Castle, vast waves of golden energy were generated.

Spreading like ocean water, they extended in all directions...

The entire Black Iron Castle seemed to be enveloped in it.

All the trial-takers bathed in the golden energy, radiating a strong vitality.

At the same time, from the depths of the Black Iron Castle, a golden figure, radiating brilliant light, soared up like a rocket.

Boom!

Boom!

Boom!

This figure was seen punching randomly into the sky, causing explosions in the void and surges of energy.

The multitude of monsters gathered above the Black Iron Castle were instantly struck heavily, crushed by the space...

The forms of numerous monsters exploded instantly, turning into a rain of flesh and blood.

But before these remnants could hit the ground, they spontaneously combusted.

Turning into blood fire, they burned to ashes in the air!

...

"It’s Waldo!"

"Waldo has come out! Has he been promoted to a level four trial-taker?"

"Such a powerful aura, although Waldo has just been promoted to level four, the feeling he gives me seems even more terrifying than that level five monster!"

"Oh my god, I thought we were doomed, if it weren’t for Waldo’s breakthrough at the critical moment, we might all have died!"

"Thank goodness, we’re saved!"

"Waldo at level four is equivalent to a level five monster! With the power of the Black Iron Castle, we can even withstand more terrifying monsters!"

"Waldo, kill the level five monster!"

"Go Waldo, you are our savior!!!"

...

Inside the Black Iron Castle, many trial-takers were shouting excitedly.

It’s no wonder they felt this way.

Not long ago, they were all close to despair.

At the crucial moment, Waldo appeared.

Like a ray of light in endless darkness.

...

"Die for me!"

Waldo snorted coldly, his terrifying aura emanating.

In the sky, there was a spectacular display.

Angry Fire Lotus blossoms bloomed, their petals falling like meteors. 𝕗𝐫𝐞𝕖𝕨𝐞𝗯𝚗𝕠𝘃𝐞𝚕.𝐜𝗼𝚖

Countless monsters were wailing in the flames, devoured and burned to ashes without even leaving dust!

At the same time, there was also a terrifying giant snake formed of condensed fire.

It seemed to have its own consciousness, rampaging through the army of monsters, devouring unknown numbers of them!!!

"Roar!"

"Roar!"

...

The monsters wailed and stampeded, sensing the terror of Waldo and trying to flee.

This scene was truly shocking.

The trial-takers were equally astounded.

One person, actually battling an army of a hundred thousand monsters!

And upon his arrival, he was about to crush the entire army!

What kind of strength does this require?

Terrifying!

Waldo at level three was already extremely fearsome.

His strength was so immense that it suffocated all the trial-takers.

Now, as a level four trial-taker, Waldo was even more powerful, beyond all the trial-takers’ imaginations.

What kind of monster is this!

"Roar!!!"

In the sky, the level five monster looked at Waldo with immense anger.

Subsequently, the wings behind it vibrated.

The reversing whirlwind howled like blades.

A flame serpent rushing towards it was blocked in the storm.

However, the flames wandered around, engulfing even more monsters into the fire.

The level five monster was extremely angry, its eyes blood-red.

Then, with murderous intent, it pounced towards Waldo.

Its heart was filled with immense rage.

It wanted to kill this audacious trial-taker on the spot!

Otherwise, it couldn’t quell the nearly endless anger in its heart.

Boom!

Thunder rolled, and pitch-black lightning tore through the night sky.

An energy storm, centered around the monster, rapidly spread out, causing the surrounding monsters to be thrown by the sweeping energy.

Crack!

It was like lightning splitting the night sky!

The level five monster had already reached in front of Waldo!

"Roar!"

A pale white bone spear lunged towards Waldo!

However, at this moment, a look of mockery and disdain appeared in Waldo’s eyes!

"Scram!"

Waldo’s figure suddenly turned into a shadow and disappeared from the spot.

In a blink, he reappeared behind the monster.

Then, a long spear appeared, piercing through the void.

Carrying an aura of world-destroying power, a destructive force swirled around it.
