There was a hint of excitement and nervousness in her voice, her finger hovering over the launch button, awaiting the captain's order.

Xu An immediately turned to look at Tang Xi, his eyes gleaming with hope: "Alright, prepare to launch! Friends from the Space Development Department, please help us block the black-robed man and buy time for Tang Xi to launch the jamming signal!"

There was a hint of pleading in his voice as he looked at the members of the Space Development Club.

The members of the Space Development Department nodded one after another. They quickly adjusted their positions, forming a solid line of defense and using colorful light to resist the attack of the golden threads.

Tang Xi saw the right moment and pressed the launch button. The jamming signal shot towards the condenser at high speed. The signal, carrying everyone's hope, drew an arc in the cave.

Chapter 660: The Appearance and Plan of Wild Explorers

However, just as the interference signal was about to touch the condenser, the man in black robe seemed to sense the danger. His eyes suddenly narrowed and a ferocious expression appeared on his face.

He suddenly gave up attacking everyone and focused all his efforts on controlling a powerful golden energy to intercept the interference signal.

This golden energy was thicker than before, and extremely fast, approaching the interference signal in the blink of an eye...

At this moment, Akai, a young technician from the Space Development Department who had been observing "723" from the sidelines, suddenly shouted, "Wait, I have a way to increase the strength of the jamming signal!"

There was a glint of confidence in his eyes, and his fingers moved quickly on the small device he was carrying.

Upon hearing this, Xu An immediately turned to look at Akai: "Akai, hurry up! We don't have much time!"

There was a hint of anxiety in his voice, and beads of sweat appeared on his forehead.

Akai took a deep breath, his forehead covered in sweat, his fingers trembling slightly, but his eyes were firm: "I'm adjusting the frequency to synchronize with the interference signal. If successful, the intensity of the interference signal will be increased by three times!"

As he spoke, he stared at the device screen, where the data was jumping rapidly.

At the same time, the black-robed man's golden energy was getting closer and closer, and was about to collide with the interference signal.

Li He was extremely anxious and rushed towards the golden energy in his mecha: "I'll stop it and buy time for Akai!"

There was a determination to die in his eyes, and the weapon in his hand spewed out flames, trying to block the golden energy.

The golden energy collided with Li He's attack, causing a violent explosion. Li He's mecha was shaken and some systems malfunctioned, but he still gritted his teeth and persevered.

"Everyone, hurry up, I can't hold on any longer!" Li He shouted, with a hint of fatigue in his voice.

Sweat dripped from Akai's forehead onto the device, and his hands trembled slightly with nervousness. However, he stared intently at the screen, muttering to himself, "It's almost there, it's almost there... Now!"

As he pressed the last button, the jamming signal instantly shone brightly, its intensity increasing dramatically. It successfully broke through the black-robed man's golden energy interception and continued to fly towards the condenser...

Just as the jamming signal was about to hit the condenser, the energy in the cave suddenly underwent a strange change. The previously stable energy fluctuations became extremely chaotic, and a powerful backlash force surged out of the condenser, attacking everyone...

The powerful backlash surged like a surging undercurrent, sweeping over in an instant, like a maddened ancient beast, carrying the aura of devastating destruction...

Xu An's pupils suddenly shrank, his eyes widened, his eyes full of vigilance and determination, and he shouted: "Everyone be careful, resist with all your strength!"

He operated the mecha with his hands at a dizzying speed, turning the energy shield to the maximum.

The blue light flickered violently under the impact of the backlash force, making a crackling sound, as if it would shatter at any time.

Tang Xi's fingers tapped frantically on the keyboard, his nails colliding with the keyboard 4.0 and making rapid tapping sounds, trying to analyze the composition of this backlash force.

Sweat slid down her cheeks and dripped onto the operating table, leaving a small stain.

"Captain, this backlash force contains all the energies absorbed by the condenser. It's too complicated, and it's hard for me to find a way to deal with it!"

Her voice was filled with anxiety, her tone unconsciously rising, her eyes filled with worry, her brows furrowed tightly into a frown.

Chapter 661 A huge crack appeared in the cave. What is awakening?

Li He was driving the damaged mecha. Although the fuselage was still smoking and some parts were crumbling and making creaking sounds, his eyes were firm and he rushed forward without hesitation.

"I'll hold the front, you guys figure out a way!" He roared, his voice hoarse from exerting so much force.

The weapon in his hand continuously emitted energy beams, trying to weaken the impact of the backlash force. The beams flickered in the darkness like sharp swords.

The members of the Space Development Department also took quick action. Their movements were in unison and they cooperated well. Years of space exploration had enabled them to develop a high degree of coordinated combat capabilities.

They formed an energy array, and the colorful lights converged together to form a solid barrier. The light was like a flowing rainbow, emitting a mysterious power.

The leading man shouted, "We must hold on together. We can't let this force get out of control!"

His voice was firm and powerful, echoing in the cave and giving everyone a shot of confidence.

Akai stared at the device screen nervously, beads of sweat rolling down his forehead, one after another, dripping onto the edge of the device.

"I'll try adjusting the frequency of the jamming signal to see if I can neutralize this backlash!"

His fingers trembled slightly, but he operated the equipment quickly. His eyes showed a determination to burn his boats, and his lips were tightly pursed into a line.

Just as everyone was struggling to hold on, the virtual and quiet entity that had been hidden in the darkness suddenly emitted a soft blue light. The blue light was like the warm spring sun, giving people a feeling of tranquility and peace.

The moment the blue light came into contact with the backlash force, the chaotic energy fluctuations actually stabilized slightly.

The ethereal voice of the Void Entity echoed: "Use the power of balance to resolve the chaos. You must find the balance point of energy."

Xu An's heart moved, and a flash of inspiration came to his mind. He shouted into the communicator: "Tang Xi, analyze the intersection of the energy of the virtual and quiet entity and the backlash force, and find the balance point! Akai, adjust the interference signal according to this balance point!"

Tang Xi immediately focused his attention, his eyes fixed on the data jumping on the screen. His focused expression seemed as if the whole world was left with only these complicated numbers.

"Found it! Captain, there's a brief equilibrium point at 30 Hz in the energy fluctuation!"

There was a hint of excitement in her voice and a blush of surprise on her face.

Akai responded quickly, quickly adjusting the frequency on the device with his fingers, staring at the screen without blinking, afraid of missing any details.

"Adjustments completed, jamming signal about to be launched!"

The interference signal was shot out again, this time with a precise frequency, rushing straight towards the core of the condenser and backlash force, like a homing pigeon with a clear target.

Under the influence of the interference signal, the impact of the backlash force gradually weakened, and the golden threads became less violent. Their speed slowed down, and their light became much dimmer.

Seeing this, the black-robed man's expression turned extremely ugly. His already gloomy face seemed to be covered with a layer of dark clouds. He roared madly, trying to control his strength to fight back again.

"You bunch of ants, don't even think about ruining my plan!" His voice was sharp and piercing, filled with anger and unwillingness.

However, at this moment, a huge crack suddenly appeared on the top of the cave, and bursts of roars came from the crack, as if some ancient existence was about to awaken.

A mysterious cosmic ray penetrated the gap and shone on the condenser.

Chapter 662: The pursuit and the difficulties encountered in the underground river?

This ray carries an ancient and mysterious power. Its light twinkles like a star, producing a wonderful resonance with the various energies in the cave, causing the entire cave to vibrate slightly.

Xu An looked at the ray and felt an inexplicable premonition in his heart.

"Everyone, stay calm. This ray might be a turning point! Tang Xi, analyze the energy composition of the ray!"

Tang Xi operated the device quickly, his fingers jumping on the keyboard, a hint of surprise flashed in his eyes.

"Captain, this ray contains a special particle that can purify dark energy. It's similar to the energy in the Space Development Department's weapons!"

Her voice trembled slightly with excitement, and her eyes sparkled with hope.

The man who led the Space Development Department also noticed this. His eyes lit up and he spoke loudly.

"We will adjust the energy frequency of our weapons to match that of the rays, and use their power to purify the black-robed man's dark energy!"

Everyone acted quickly, and the colorful light and the power of the rays gradually merged, covering the man in black robes. The light became brighter and brighter, as if to completely dispel the darkness.

The man in black robe was caught off guard by the sudden attack. His body trembled violently in the light, his face showed an expression of pain, and his facial features were distorted.

"No, this is impossible!" He struggled frantically, waving his hands in the air, trying to break free from the light, and kicking with his feet, but in vain.

At this critical moment, Xu An, Tang Xi and Li He cooperated tacitly.

Xu An drove the mecha towards the man in black robe. The engine made a huge roar, attracting his attention; his eyes were fixed on the man in black robe, like a cheetah staring at its prey.

Tang Xi continued to analyze the energy fluctuations of the man in black robe, her eyes fixed on the screen, providing attack directions for Xu An and Li He. Her fingers kept tapping on the keyboard, and her forehead was covered with sweat.

Li He attacked from the flank, looking for the black-robed man's weakness. His mecha moved flexibly, and his eyes were sharp and decisive.

As the purifying power continued to grow, the black-robed man's golden threads gradually dissipated and turned into tiny specks of light. His strength was also rapidly weakening, and he looked increasingly weak.

But just when everyone thought victory was in sight, the man in black robe suddenly let out a desperate roar. The sound was like the wail of a wounded beast, which was creepy.

He gathered all the remaining dark energy together, forming a massive energy ball. The energy ball was as black as ink, surrounded by strange purple lightning, and smashed towards everyone...

At this moment, the new supporting character who had been observing silently in the corner of the cave - an old man who was well versed in cosmic mysticism, slowly stood up.

His body was hunched and his face was covered with wrinkles, but his eyes were deep and bright, revealing a wisdom that saw through everything.

"Wait, this energy ball contains an ancient curse. Direct contact will cause an even greater disaster!"

His voice was hoarse but powerful, echoing in the cave.

Xu An (Zhao Liaohao) immediately turned to look at the old man, his eyes filled with anxiety and expectation: "Old man, what should we do? You must have a solution, tell us quickly!"

There was a hint of pleading in his voice, and his hands unconsciously clenched the joystick.

The old man pondered for a moment and slowly said, "Perhaps we can use some special material in the cave to construct an energy buffer field to disperse the power of this energy ball. But this requires precise calculations and powerful energy support."

Chapter 663: It's like a bright light is lit in the darkness

Upon hearing this, Tang Xi immediately said, "I can try to calculate the construction parameters of the energy buffer field, but energy support..."

At this time, a young member of the Space Development Department stepped forward, his eyes radiating confidence and determination. "We have a powerful energy core on our Space Development Department spacecraft. I'll go get it. It should be enough to meet our needs!"

Xu An nodded and said, "Alright, there's no time to lose. Go quickly and come back soon! The others continue to hold back the man in black robes. Don't let him have another chance to attack!"

The young members of the Space Development Department rushed towards the spacecraft like an arrow from a bow, their steps 723 hurried and firm, their figures flashing by in the dim light.

The battle in the cave became increasingly fierce. The air seemed to be ignited by the flames of war, filled with tension and danger.

The man in black robe used up his last bit of strength, his facial muscles twisted, his eyes bloodshot, and he controlled the energy ball containing the ancient curse, smashing it down towards everyone with a crazy momentum of mutual destruction.

Purple lightning raged around the energy ball, crackling and scattering, casting a strange and eerie light on the cave. Each streak of lightning was like the scythe of death being swung.

"Everyone, follow what the old man said and prepare to build an energy buffer field!" Xu An shouted loudly, his voice echoing in the cave with unquestionable determination. His face flushed slightly due to the effort, and his eyes flashed with determination.

He drove the mecha and quickly searched for traces of special substances in the cave. The engine of the mecha made a low roar. His eyes were sharp and focused. He did not miss any corner and captured every subtle clue.

Tang Xi sat in the mecha cabin, his forehead covered with fine beads of sweat, a few strands of hair soaked with sweat and stuck to his cheeks, his hands tapping rapidly on the keyboard, his nails hitting the keyboard and making a rapid sound, the data on the screen flowed like a waterfall.

"Captain, the parameters have been calculated almost, but the energy core is not in place yet, and time is running out!" There was a hint of anxiety in her voice, and her tone unconsciously rose. Her eyes were fixed on the countdown numbers, and every beat of the numbers seemed to knock on her heart.

Li He drove the scarred mecha and continuously fired energy beams, trying to disrupt the rhythm of the man in black robe.

"I'll try to hold him back, hurry up!"

The outer shell of his mecha was damaged in many places, revealing the internal circuits and parts. Thick smoke billowed out from time to time, making a sizzling sound, but his eyes remained firm, with no intention of retreating. It seemed as if his eyes were declaring to the enemy: Don't even think about succeeding easily.

The members of the Space Development Department surrounded the man in black robes, with colorful lights flashing continuously, trying to restrain his actions.

The leading man shouted, "Everyone, hold steady! We can't let him increase the power of the energy ball!"

His voice was steady and powerful, echoing in the cave like a huge bell, giving everyone a shot of adrenaline and allowing them to calm their minds in this tense battle.

Just as the energy ball was about to fall, the young member who went to get the energy core rushed into the cave, holding the core and panting.

His chest heaved violently, he gasped for breath, his forehead was covered in sweat, and his hair was soaked with sweat, strands sticking to his face.

"I'm back!" he shouted, his voice tired yet full of hope, like a lamp lighting up in the darkness.

Chapter 664: Must Ensure Absolute Safety

Xu An quickly took the energy core and installed it on the pre-prepared device.

"Tang Xi, activate the energy buffer field!" His voice was firm and urgent. His eyes were fixed on Tang Xi's operation, and his hands were clenched unconsciously, as if preparing for the upcoming impact.

As Tang Xi pressed the start button, a transparent energy shield slowly rose, emitting a soft light. The light was like a protective film, enveloping everyone.

The moment the energy ball collided with the energy buffer field, a deafening roar was heard, as if the sky was collapsing and the earth was splitting apart. The cave shook violently, rocks on the ceiling kept falling, and cracks appeared on the ground.

The power of the energy ball was constantly dispersed in the buffer field. Purple lightning ran everywhere, hitting the surrounding stone walls, splashing countless sparks. The sparks flickered in the darkness like stars in the night sky.

The man in black robe saw that his last killing move was broken, and a look of despair and unwillingness appeared on his face.

His lips trembled and his face was full of disbelief.

"No! This is impossible!" He roared madly, his voice echoing in the cave, full of despair. It was like the wail of a wounded beast, terrifying.

With the joint efforts of everyone, the power of the energy ball was gradually consumed, and finally turned into wisps of black smoke and dissipated in the air.

The man in black robe collapsed to the ground due to exhaustion of strength, losing the ability to resist. His body fell limply like a tattered rag doll.

Everyone finally breathed a sigh of relief and sat down exhaustedly in their respective mechas.

Some people leaned back in their seats, closed their eyes, and gasped for breath; some took off their helmets and wiped the sweat from their faces with their hands.

However, before they could rest properly, Xu An's communicator suddenly rang.

"Xu An, return to the base immediately, there is an urgent mission!" The superior's voice was serious and urgent, as if carrying an invisible pressure.

Xu An frowned slightly, feeling a little uneasy, but he quickly responded: "I understand, I'll return immediately." His voice was steady and decisive, without any hesitation.
