Three hundred years later, the earth has become a purgatory, with billions of zombies running rampant. When the "Long Yuan" special operations team unexpectedly crossed over with a full complement of modern heavy firepower equipment, a crushing counterattack began!

From fighting alone to rebuilding human civilization, from being hunted to becoming hunters, this special operations team from the past will use steel and flames to write a new legend in the doomsday wasteland!
