Soon after, Opal and Casey rushed towards the basement second floor.
The whole process happened in the blink of an eye, taking only about half a minute in total.
From the basement first floor to the seventh floor, the scenes were similar – each floor guarded by a mid-to-late stage Saint elder with a group of armored soldiers.
The elder on the seventh floor had already reached the ninth-rank Saint realm, the same as Casey.
However, with Casey wielding the Celestial Blade, even without using his trump card, he could contend with a half-step Divine Realm expert, effortlessly resolving the battles with a single slash.
In less than five minutes, the two arrived at the bottom floor.
Looking around, they saw a large space with a cage in the middle, about ten meters in length, width, and height.
A middle-aged man and woman were sitting weakly inside the cage, clearly heavily injured.
The two were none other than King Rhett Byrne and his wife from Tengamine Kingdom!
To Opal and Casey’s surprise, there was no one guarding inside.
“Why isn’t anyone guarding down here?” Casey furrowed his brows slightly.
It was clear that things were not as simple as they appeared!
Without being able to speak, it was evident that King Rhett Byrne and his wife were likely silenced by some means.
“Be careful!”
Just then, Opal exclaimed.
Swish! Swish! Swish!
As she spoke, sharp and powerful energy blades swept towards them, formidable enough to slay a late-stage Saint expert.
“Opal, go rescue them, I’ll handle these energy blades!” Casey shouted, swinging his Celestial Blade towards the incoming threat.
“I knew today wouldn’t go too smoothly!” Opal’s expression changed slightly.
“What’s wrong?” Casey asked as he acted.
“There’s a barrier set around the cage!” Opal replied with a solemn expression.
“Hmm?” Casey’s pupils slightly constricted. “Why is there a barrier? Why didn’t Rayan Byrne mention this to us?”
“It’s possible that it was recently set up, he probably didn’t know either!” Opal responded.
“What should we do?” Casey furrowed his brows slightly.
“I’ll give it a try!” After taking a deep breath, Opal exerted her full strength and struck the barrier with a palm.
Boom!
A loud noise reverberated, causing the entire space to tremble with debris falling from the ceiling.
However, the barrier only wavered slightly without showing any signs of damage.
“Dammit!” Casey frowned again.
The mood of the two sank simultaneously.
“Let’s forget it, let’s go!” Opal took another deep breath and spoke.
Staying here for another minute would only increase the danger.
Estimating that in four or five minutes at most, Jared Byrne would arrive with reinforcements!
By then, not only would they fail to rescue the captives, but they would also find it challenging to escape. Under the circumstances, they had no choice but to give up.
“Opal, you hold off these energy blades for me, I’ll try!” Casey also took a deep breath before replying.
He knew very well that if they couldn’t rescue Rhett Byrne, they would be in grave danger.
If Jared Byrne mobilized the entire kingdom to hunt them down, they would be in a very precarious situation!
“Okay!”
After a brief thought, Opal nodded in response, then raised her hand and swept out palm strikes towards the energy blades.
Whoosh!
Following that, Casey’s eyes narrowed as he unleashed a Celestial Blade Art with twelve-fold power towards the energy blades.
Boom!
The thunderous blade curtain struck the barrier, emitting a deafening noise, causing the entire prison to tremble intensely again.
Celestial Blade Art and Celestial Blade complemented each other, doubling the power when used together.
The power of this strike even surpassed the palm strike Opal had previously unleashed.
However, it still had no effect as the barrier wavered but remained intact.
However, at that moment, the onslaught of energy blades in the space had already dwindled, gradually calming down.
“Casey, let’s try together!” Opal spoke in a deep voice.
As she spoke, she pulled out the Heartless Sword that Harleen had specially asked her to bring.
“Alright!” Casey responded loudly.
In the next moment, the two acted without hesitation, each unleashing their most powerful trump cards.
With a sword and a blade, carrying destructive energy, they struck towards the barrier.
Boom!
Strong shockwaves rippled out, causing numerous rocks to fall from the ceiling and walls, creating an earthquake-like effect.
“Still no success?”
After the commotion settled, Casey frowned and gazed at the barrier ahead.
“Let’s leave it, come on!” Opal exhaled a breath and spoke.
“Mm!” Casey exhaled as well and nodded.
He knew very well that if they didn’t leave now, they might not be able to make it out safely.
Crack!
Just as the two were about to turn around, the barrier in front emitted a crisp sound.
Following that, a long crack appeared on the barrier.
“Hmm?” Casey’s eyes lit up. “Is there hope?”
“Let’s try again!” Opal began simultaneously.
“Okay!” Casey nodded vigorously.
Subsequently, the two attacked once more.
Without much surprise, after a loud noise, the crack widened significantly, enough for an arm to reach through.
Once there was hope, they naturally wouldn’t give up.
Rumble!
After their fourth attempt, the barrier that shrouded the cage collapsed with a resounding crash, dissipating into nothing.
“We did it!” Casey raised his eyebrows.
Without any hesitation, he swiftly turned his wrist, sending a curved blade towards the iron chain securing the door.
Clang!
The chain broke and fell to the ground.
Inside the cage, King Rhett Byrne and his wife tried to speak again, but no sound came out.
“Let’s go!”
Opal entered the cage, grabbed Rhett Byrne’s wife, and hurried towards the stairs.
Casey wasted no time, lifting King Rhett Byrne and following closely behind.
Meanwhile, a boundless and terrifying pressure enveloped the entire military camp.
The ordinary soldiers in the camp felt suffocated, many collapsing on the ground, trembling with fear on their faces.
Standing atop the prison, Billy’s face revealed solemnity.
When Opal and Casey were attacking the barrier together, he had a bad feeling.
Based on their earlier estimate, Opal and Casey should have arrived within seven to eight minutes at most, but now there was still no sign of them, indicating that something had gone wrong.
He had intended to go down and check, but just as he was about to move, he sensed three powerful auras heading towards the military camp.
Undoubtedly, it was Jared Byrne, his deputy general, and another third-rank Divine Realm expert.
“How dare you dare to raid the prison, you don’t know the gravity of your actions!”
A man’s voice resounded through the air.
As the voice fell, three figures appeared within Billy’s line of sight, with Jared Byrne leading the way.
In his fifties, with thick eyebrows and a sturdy figure, he exuded a chilling aura of hostility.
