“Again,” Grimbolt growled.

He attacked once more with all three tons of weight pushed by pistons powered by desperation and promise.

This time, a sharp cracking sound was heard. One of the giant hinges at the top snapped, sending a shower of rust dust down. The gate tilted slightly, creating a small gap on one side.

“He broke through!” the Vexxos team shouted again.

Grimbolt didn't stop. He struck again a third time, hitting the exact same spot. A painful metallic screech, and finally, the second hinge broke.

The giant gate fell, crashing into the tunnel on the other side with a deafening crash. The impact even created a makeshift bridge over the deep sewer.

Meanwhile, Valerius remained hunched over, closing his eyes and holding his head to prevent the rain of rust dust from hitting him.

Grimbolt stumbled forward with smoke billowing from his dented shoulder.

“Continue,” Grimbolt ordered Valerius.

Valerius raised his head. The fallen gate opened before him.

“We move,” Grimbolt said again as Valerius froze in place.

They crossed the fallen gate and began running again in the darkness. Behind them, the Vexxos soldiers stopped at the edge. They hesitated as they crossed the unstable bridge.

“Damn it!” the team commander roared as he saw his prey escape. “Notify Kael! Iron Sentinel is fully operational. Repeat, fully operational! He’s taking the prince to the Old Pipe Sector. We need an intercept team there, now!”

Valerius looked back. He stared at Grimbolt, who was moving slower than before. Every step the robot took seemed to be in pain.

“You… you’re hurt,” he said shakily.

“Minor structural damage,” Grimbolt replied. A red warning light was flashing on his internal HUD. “Irrelevant.”

“Relevant or not,” Cogs yelled from Grimbolt’s grasp, his vocalizations clearer now. “The fact that you’re using your head as a sledgehammer shows our current strategy is less than… subtle.”

“We need a place to hide,” Valerius said. He recognized the truth in the crow’s sarcastic words. “A place they won’t think to look for us.”

“I’m counting,” Grimbolt replied, his optics scanning the damp brick walls around them. “There are hundreds of kilometers of tunnels beneath this city. We just need to find the one we’ve forgotten.”

“You better find them quickly,” Valerius said as he heard the wailing sirens coming from above. The sound was seeping down through the ventilation ducts. “Because it doesn’t look like they’re going to forget about us anytime soon.”

“They’re directing patrols to the Old Pipe Sector,” Grimbolt replied. The massive robot was processing the Vexxos radio transmissions it had finally intercepted. “They predict we’ll be looking for hiding places among the older, less-mapped infrastructure. They’re very intelligent.”

“And we were going that way,” Valerius said. His voice was tense. “So we have to turn around now?”

“Negative,” Grimbolt replied again. “Turning back will only lead us to the main force pursuing us. Our best option is to advance and try to bypass their blockade before they have a chance to firmly establish it.”

“In other words,” Cogs squealed from Grimbolt’s grasp, “we’re running from the wolf’s den straight into the crocodile’s mouth. What a brilliant strategy. The Queen will be impressed.”

“Shut up, you trashy crow!” Valerius hissed, furious at Cogs’s remark, which he considered so noisy. “I wonder why Mother is so happy to keep you,” he grumbled.

“I’m just stating the facts!” Cogs replied matter-of-factly. “The fact that we’re being led by a dented locomotive and a panicking prince!”

Grimbolt raised his free hand to stop Valerius from speaking. They were now in a large circular room.

The chamber was the center of several converging tunnels. In the center of the chamber stood a giant, rusty valve protruding from the ceiling, surrounded by thick, hissing pipes.

“Valve junction,” Grimbolt whispered. “They’re already here.”

“I don't see anyone,” Valerius replied.

His blue eyes tried to clear the darkness. Nothing. He couldn't see anything but darkness.

“They’re waiting,” Grimbolt said, his yellow optics narrowing. “There. On the pipe. Twelve o’clock.”

Valerius raised his head. Atop one of the largest horizontal pipes that crisscrossed the room, a small, dark silhouette was moving. A Vexxos soldier was crawling into position, ready to fire.

“And there,” Grimbolt continued. “Behind that support pillar. Three o’clock. There are two people.”

Valerius turned his head again. He could now see the faint glint of a soldier's rifle. It was an ambush. They were already heading straight in.

“So, what are your plans now, grand strategist?” Cogs asked. His tone was now more tense with sarcasm laced with genuine anxiety.

Grimbolt responded with action. With a surprising movement, he pushed Valerius forcefully behind the giant valve in the center of the room.

“Stay down!” Grimbolt ordered.

“Grimbolt!” Valerius shouted.

Just as Valerius fell into the shelter, the hell-like place broke loose.

Blue energy bolts shot from the three directions Grimbolt had indicated. They struck where they had just been standing, leaving sizzling scorch marks on the wet stone floor.

Grimbolt ignored the gunshot that hit his back. The massive robot focused on the most pressing threat, the sniper on the pipe. He grabbed a piece of brick that had come loose from the wall and, with incredible piston force, threw it.

The bricks flew like bullets and struck the pipe directly beneath the soldiers. The soldiers lost their balance and fell awkwardly to the floor below, their weapons thrown.

Two soldiers behind the pillar came out of hiding and fired a burst of shots. Grimbolt, who was still in pain, glitch His motor system was unable to dodge quickly. One of the soldier's shots hit his left knee joint, sending him to his knees with a painful metallic creak.

“Status! He’s been shot!” shouted one of the soldiers. “Move forward!”

“Mistake,” Grimbolt growled. Kneeling didn’t weaken him. It made him even more stable.

Grimbolt used his hand to push on the giant valve in the center of the room. The valve, which hadn't moved in decades, initially resisted, refusing to budge at all. Then, with a deafening metallic groan, the wheel finally began to turn.

“What are you doing?!” Valerius shouted from his safe hiding place.

He saw with his own eyes that Grimbolt was trying to get out of all the threats with broken movements because the system in the robot's body was damaged.

“Increase the pressure!” Grimbolt replied.

The thick pipes around the room began to vibrate violently. The hiss of steam turned into a deep, powerful roar.

The Vexxos soldiers stopped. They looked around in confusion. “What is that? What is he doing?”

In one of the large pipes above their heads, a joint that had rusted for years finally couldn't withstand the sudden increase in pressure. With a deafening explosion, the joint burst.

A jet of boiling, high-pressure industrial wastewater erupted. The thick, brown liquid immediately filled the air with a pungent, acidic odor. The jet hit the ceiling, sending a hissing rain across the room.

“Wow!” Valerius took a step back as he saw the scene before him. A mixture of amazement and shock.

The two soldiers screamed as the hot liquid hit their armor, causing it to smoke and melt. They stumbled back to protect their faces, their weapons forgotten.

Grimbolt didn't give a chance. He lunged forward from his kneeling position, ignoring the pain in his leg. He slammed into the first soldier and sent him flying into the wall. He grabbed the second soldier with his massive hands, lifting him off the ground.

“Where is Commander Kael?” Grimbolt demanded, his optics glowing a fiery red just inches from the terrified soldier’s helmet.

    One year has passed.That morning, the city was not woken up by curfew sirens or tear gas hisses. Instead, the sound of music from a gramophone echoed in the square, answering the hammer clinks of workers rebuilding the East Sector connecting bridge. The air no longer smelled, but rather of fresh bread and steam billowing from public heating pipes that were now free for anyone.In an open workshop on the outskirts of the palace wing, a fifteen-year-old young man was kneeling on an oil-stained floor. His face was splattered with engine grease, and his hands which were now muscular and calloused were busy adjusting a pressure valve on a steam prosthetic leg for a war veteran.Valerius Alaric. The people no longer called him the "Lost Prince". On the streets, they knew him as the "Shadow Mechanic"."Done," muttered Valerius then wiped the sweat on his forehead with the back of his hand. "Try moving it, Silas."Silas, the old man who used to climb the ice mountain with him, moved his new

    "Please..." Kael crawled on the floor, his hand reaching out towards Valerius. "Open the door... I will turn it off... I promise..."Valerius stared at the hologram monitor. The bomb countdown showed two minutes. Their time was truly almost up, both from the explosion and from their giving-out lungs.Valerius stepped closer to Kael then bent down slightly so his face was level with the man who had destroyed his family. He let Kael see that in his eyes, there was not the slightest intention to negotiate anymore."I don't need to turn off your bomb, Kael. I just need to lock the door and let you suffocate with me in this room.""You... you're just bluffing! You are crazy! You wouldn't dare leave your life here!"Kael screamed with a high-pitched voice. He crawled on the marble floor, his hands clutching his chest. The oxygen in the Throne Room had depleted. His vision began to blur, every breath he took only brought a burning sting to his lungs.Before him, Valerius was no longer standi

  • CHAPTER 120: THE FINAL BLUFF

    "I don't need anyone's help!" snapped Kael."You do," cut Valerius sharply. "Because out there, those people you call pathetic are tearing your Praetorian forces apart. Without direct orders from you, they are just brainless machines. You are losing, Kael. And you are terrified."Valerius imitated Kael's way of speaking which was condescending but full of calculation. He stopped acting like a hero and began to act like a ruler playing poker with lives as the stakes."This is my offer," said Valerius. "You turn off that device voluntarily, and I will let you be tried fairly. You might spend the rest of your life in an underground prison, but you will still breathe. You will still have that 'life' you worship so much.""And if I refuse?" challenged Kael, his eyes glancing towards the hologram monitor showing an eight-minute countdown to detonation."Then we both will die here," answered Valerius without the slightest hesitation. "And believe me, Kael, I already lost everything one year

    "I will not let you die alone, Grim!" shouted Valerius without looking back, his voice piercing through the hissing steam and the boom of metal.Valerius ran fast across the cracked marble floor, dodging the silver liquid shrapnel splattering from the brutal fight between Grimbolt and The Argentum Shade.In front of him, Commander Kael seemed to take a step back, his trembling hand fumbling for something on the arm of the Sun Throne. The elegance he displayed earlier evaporated, replaced by the lines of panic of a tyrant realizing his fortress had been breached."Stop right there, Prince!" roared Kael.He pulled a small energy pistol from inside his coat and fired wild shots.Valerius rolled on the floor, using the carcass of a destroyed Praetorian robot as temporary cover, then lunged forward again. The anger he had buried for a year—. More precisely since the night his mother fell covered in blood, was now concentrated at the tip of his short sword.Kael no longer tried to shoot. Wi

  • Chapter 118: BLOODY WELCOME

    The white dust from the ruined tungsten gate still hung in the air like fog as Valerius stepped into the grand corridor leading to the Throne Room. Every step left dirty boot prints on the marble floor.The atmosphere inside the palace was so quiet, a suffocating silence, sharply contrasting with the echo of war still raging in the outer courtyard.Grimbolt walked right behind him. The sound of the Sentinel's footsteps was no longer light metal clinking, but bass thumps vibrating the building's foundation. His scorched black chassis emitted a constant hiss of steam, and the heat radiating from his body made the air around them ripple."Cogs, report," whispered Valerius to his communicator."I'm still up here, Golden Boy! I'm between the ventilation pipes right above the throne," Cogs's voice sounded small but sharp. "Kael is alone there. I mean, biologically he is alone. But my infrared sensor caught something... strange. There is a mass of cold energy behind the throne. Be careful, t

    "You failed to guard this door before, old machine! You will fail again now!"That Vexxos Captain's voice shrieked full of insult from behind the concrete barricade on top of the palace wall, followed by a mocking laugh that echoed through the loudspeakers.Below him, hundreds of laser rifle barrels and Nanotech grenade launchers simultaneously locked onto a single position in the middle of the courtyard, which was Grimbolt. The Sentinel stood tall, letting his giant body become an open target under the Neo-Alexandria sky which was now the color of hot copper."Target locked! Annihilate that scrap!" ordered the Captain.Instantly, a rain of projectiles and energy beams showered Grimbolt. Explosion after explosion hit his Titanium-X chassis.Bartholomew ducked behind the ruins of a pillar, pulling Valerius so he wouldn't be hit by metal shrapnel. The mute giant gripped his hammer
