In 2280 AD, human civilization collapsed, and the survivors were trapped in Iron Dome City. Outside the city was a wasteland where mutated monsters were rampant, and inside the city was a purgatory with the dictatorship of the city lord and a strict hierarchy.
A Ye, who had lost his memory, woke up from a century-old cryopod, with only bone-gnawing hunger and inhuman fighting strength. He killed blade-clawed beasts with his bare hands and ate the monsters' flesh and blood alive. He was rescued by Wei Young, a girl from Scrap Iron Town, and became a low-level subordinate with nothing. In order to obtain a legal identity, he hid his strength and participated in the selection of mecha masters. He surprised the audience with a fitness level of 52%. Little did he know that he was the ultimate product of the biochemical experiment a hundred years ago - the only survivor of the S series, the "Blade of Winter."
The tyranny of Iron Dome City intensified, with city defense fees exploited, rations reduced, and even "purification orders" issued to expel civilians. The idealistic mecha master Wang Yu sacrificed his life to protect civilians, completely igniting the anger of resistance. Aye awakens his memory in battles and protections, and reveals the shocking truth: he is the ultimate weapon created to protect mankind, and the leader and ruler of the monsters outside the city is actually an out-of-control experimental subject with the same origin as him.
From an amnesiac just for food to a guardian with a mission, Aye led the low-level civilians in Area D to form a resistance army, retreated to the underground city a hundred years ago, awakened dusty weapons, united with the justice mecha masters, and declared war on the god-killing city lord Helian Ji.
When order collapses and civilization is in danger, the Blade of Winter is unsheathed, using a mortal body to tear apart mechas and sweep away monsters, overthrowing the corrupt dictatorship and rebuilding a new life of equality.
This is a passionate uprising in the wasteland, and it is also an apocalyptic legend about protection, resistance and humanity.
