Monsters invaded, turning the entire city into a living hell.

In this hell, Chu Fan struggled to survive for three long years.

During those years, he lost everything.

At last, after three years, he escaped the inferno with his sister still alive.

He thought the outside world would be the safety and hope he had dreamed of.

But waiting for him outside the city… was a heavily armed military blockade.

“No one leaves!”

“Get back in there!”

A general raised his hand coldly.

Bang!

A single gunshot.

His sister, ragged and in tatters, collapsed instantly.

Chu Fan’s body trembled. He stood frozen for a long time. In total despair and with endless hatred, he cradled his sister’s corpse and staggered back into the burning city behind him.

At that moment, a cold mechanical voice echoed in his ears.

【Ding. Activate Doomsday Catastrophe System?】

【Destroy this world—completely!】
