After the enormous Swamp Mud swallowed all 400 Combat Robots, that mysterious power vanished, and the ground returned to normal.
"Ten meters! Is that your limit, Boni? The puppets under my command are more than just this paltry handful!" Yang Feng sneered coldly and waved his hand. One hundred Blade Soldiers flickered into motion and swiftly reached the spot where the 400 Blade Soldiers had been swallowed. They pulled out huge bricks, drove them into the ground, and began digging and tearing apart the earth to excavate the 400 buried Blade Soldiers.
After all, Boni was merely a Level-1 Warlock. Even with the power of the Wizard Tower, the Level-1 spell Swamp Mud could only sink those Combat Robots roughly ten meters underground.
If the opponents had been humans, being buried ten meters deep would have meant certain death. But for the Blade Soldiers, they had merely been buried and rendered unable to move; they had not been damaged.
"Attack!!" a military officer roared from atop the city wall.
Massive Catapults and Alchemy Heavy Ballistas appeared one after another atop the walls.
Heavy Crossbow Bolts seven meters long and enormous boulders weighing one or two tons blasted toward the 100 Mechanical Swordsmen.
A Heavy Crossbow Bolt struck a Mechanical Swordsman in the chest, blasting its upper body to pieces as countless components scattered everywhere.
An enormous one-ton boulder fell from the sky and smashed directly onto a Mechanical Swordsman, crushing it into a twisted, distorted wreck.
Black City had the Black Hut, a Warlock organization, stationed within it, making it more than a hundred times wealthier than Giant Stone City. The various Heavy War Weapons mounted on Black City's walls also outnumbered those of Giant Stone City by more than tenfold.
Under the bombardment of those various Heavy War Weapons, Mechanical Swordsmen were blasted apart and crushed out of shape one after another.
Yang Feng watched as the Heavy War Weapons destroyed Mechanical Swordsmen one after another, yet his expression did not change in the slightest. Those Level-4 Mechanical Swordsmen had the lowest technological content. So long as their wreckage could be recovered, they only needed a small amount of energy to be melted down and reforged before they could quickly be manufactured again.
No matter how many Mechanical Swordsmen died, so long as the battle was won and their wreckage could be recovered, new Mechanical Swordsmen could be produced again. It was practically as though the Mechanical Swordsmen could be reborn without limit. That was precisely why Yang Feng could use them so recklessly—no matter how many died, he did not care.
"Fireball Spell!"
After Black City's Heavy War Weapons carried out several waves of covering bombardment and destroyed a large number of Mechanical Swordsmen, Boni pointed a finger and cast the Level-1 spell, Fireball Spell. Fireballs flew from the Wizard Tower like cannon shells, bombarding the remaining Mechanical Swordsmen and blowing them apart one by one.
Seeing the Mechanical Swordsmen blown to pieces, all the warriors of Black City atop the walls erupted into cheers, their morale soaring.
"Impressive indeed! A Warlock paired with a Wizard Tower is like a humanoid self-propelled cannon with unlimited shells! And a multifunctional humanoid self-propelled cannon at that! It seems I'll have to get a little serious!"
Yang Feng watched the Mechanical Swordsmen being blown to pieces one after another, smiled faintly, and clapped his hands.
From the forest behind Yang Feng, Mechanical Swordsmen emerged one after another.
Ten, a hundred, a thousand, ten thousand, thirty thousand—an entire 30,000 Mechanical Swordsmen marched out from behind Yang Feng, forming a dense Mechanical Legion that stretched beyond the eye's reach.
The expressions of the human warriors atop Black City's walls changed as more and more Mechanical Swordsmen appeared. When they saw 50,000 Mechanical Swordsmen divided into five legions before their eyes, every one of them turned pale, and a trace of despair flashed through their eyes.
A human military officer turned pale, his voice trembling slightly as he said, "How is this possible? How can there be so many Alchemy Puppets?"
Another human military officer, his face pale, muttered, "Impossible! An Alchemy Puppet comparable to Knight-level costs more than 3,000 Gold Coins! So many Alchemy Puppets—90 million Gold Coins! How could a mere Wizard Apprentice possess so many Alchemy Puppets? Could it be that we are facing an Alchemist of Great Warlock rank?"
When Boni, floating in midair, saw the 30,000 Mechanical Swordsmen, his eyes nearly bulged out of their sockets. He shrieked in discomposure, "No!! How can you have so many Alchemy Puppets?"
Several hundred Knight-level Alchemy Puppets were something Level-1 Warlock Boni, sheltered inside the Wizard Tower, could easily deal with. But against 30,000 Knight-level Alchemy Puppets, Boni had no confidence whatsoever.
The 30,000 Mechanical Swordsmen formed three enormous formations of ten thousand, perfectly aligned, with identical spacing and dimensions, as though they were a single whole. Every Mechanical Legion was silent and cold, more obedient and orderly than even the most elite human soldiers. Merely standing there, they radiated an immense pressure.
Yang Feng gave the cold command, "Attack!"
The three Mechanical Swordsman Legions immediately spread out and charged directly toward Black City from different directions.
"Swamp Mud!"
Boni's expression changed drastically as he swiftly cast this terrain-altering spell.
A powerful surge of energy erupted from the Wizard Tower, covering the ground before Black City and forming an enormous swamp.
Mechanical Swordsmen leaped directly into the swamp, raised their hands high, and slowly sank down, forming something like platforms.
The Mechanical Swordsmen behind them stepped on the platforms formed by those in front and charged straight ahead.
The Level-1 spell Swamp Mud cast by Boni covered an extremely broad area. Yet he was, after all, merely a Level-1 Warlock. Since its range was so vast, its depth was relatively shallow, only ten meters. Just five Mechanical Swordsmen could form a foothold platform within the swamp.
All those Mechanical Swordsmen possessed powerful computing abilities. They stepped with incomparable precision onto one foothold platform after another, swiftly leaped across the enormous Swamp Mud, and charged beneath the city walls.
As soon as the Mechanical Swordsmen arrived beneath the city walls, they rapidly formed human ladders.
The Black City warriors atop the walls poured down scalding soup and boiling oil, drenching the Mechanical Swordsmen, but it had no effect whatsoever.
Barrels of City Defense Fire Oil were poured down as well. When a torch fell into the oil, vast seas of flame erupted, engulfing the Mechanical Swordsmen.
Even as the seas of fire burned them, the Mechanical Swordsmen remained unmoved. Unless the flames reached temperatures sufficient to melt them, they would remain as unshakable as steel.
