A vast number of discarded machines carpeted the land outside the city gates.
The white Snowy Plains had now melted away, leaving only a few line-like traces.
Sunlight swept across the highest reaches of the sky, gradually sinking westward.
One heavy machine after another finally arrived before the city gates.
The once-dense mechanical force had now been reduced to only a few scattered hulks.
Only a few anti-air armored cars remained at the front. They moved aside to either flank, clearing a path for the heavy armored vehicles behind them.
Dense artillery fire continued to rain down between those anti-air armored cars and heavy machines.
Even denser fire filled the sky at the same time, coming from the anti-air armored cars in the rear.
One Mecha after another, flying through the air like dark clouds, surged toward the city walls.
They dodged the artillery fired from the walls while rapidly closing in, using their nimbler frames compared to fighter jets to launch targeted attacks on the gun emplacements atop the walls.
Beneath the Mecha, fully armed armored units covered one heavy armored vehicle after another. Their bodies resembled sledgehammers, and they rolled forward on triangular treads, rapidly approaching the city gates.
At that moment, amid the widespread artillery fire, the heavy robots at the front finally touched the city gates.
They raised their sledgehammer-like hands and pressed them against the gates.
Boom—
Violent high-frequency vibrations instantly made the entire city gate tremble, producing a thunderous roar.
Even the towering city wall seemed to shudder slightly.
The fierce vibrations spread into the narrow command center atop the high wall.
"They're trying to destroy the transmission mechanisms of our city gates through high-frequency resonance!"
A young officer seated before a screen shouted, "Some of the smaller components have already been damaged."
