When extraterrestrial entities called Wreckers go berserk on Earth and humanity is hell-bent on protecting whatever it is on land, all Jeon Jeongguk can wish is an acknowledgement form society. Simple as that. The idea that his wish will get his fate welded to the hands of a certain male soldier known as Calamity Dog is never inside his mind, and certainly he never imagines he will have to follow a path leads straight to waist-deep wreckage. Is he strong enough to get through? ForewordIn this world, nothing is going to last forever. Not even humanity. What people never imagined was that the entire race of man to be wiped out by the mere presence of another organism.When the night falls, look up at the sky and make a picture of huge question-mark-shaped constellation people prefer to call Scorpius. At the beginning of the mark, there is a pair of bright stars known as Cat’s Eyes, consisting of Shaula and Lesath. They were located so far away from Earth and so trivial that the scientists spent only a few years researching their properties before leaving them completely, losing interest. It was enough for them to know that these stars had probably been formed at the same time, and just like many other members of the Scorpii family, they had planets orbiting around. The discovery of liquid water on one of the planets’ surface didn’t even surprise them. They said that if humanity had to find a new planet to accommodate the exploding resident growth, they wouldn’t choose a planet that needed hundreds of years of confinement inside a spaceship. Something closer like Mars would be more preferable.Even so, no one knew that the planet was actually harboring lives like those on planet Earth until tens of years since its discovery. Intelligent beings lived on its surface were building civilization, developing technologies, and socializing like us humans, but in far more advanced ways. Old fictions had called them aliens. Researchers called them extraterrestrial beings—so much for the smarties—and by ‘like us humans’ it means they really were living like us humans.On planet Earth human don’t exist without competitors. Same went for them aliens. Living side-by-side with them were parasitic creatures that sucked the liquids form their bodies and spreading illnesses, like our Aedes sp. and its loyal partner Plasmodium sp. The difference was that the creatures couldn’t just be killed. When they died, they released to the air poison that was lethal for their hosts. Some scientists of this planet then suggested that they isolate and quarantine the parasites, but the scholars argued that the idea wasn’t effective. They would have to deal with the piling amount of poison once the parasites died, and that would mean they couldn’t keep using a place to prison more parasite once one of them turned into corpse. Other scientists suggested that they threw away the parasites somewhere their people wouldn’t visit. This idea was thought, considered, and reviewed thoroughly. How could they just dispose deadly creatures like that? What if they infected other organisms?As infection rate escalated, the idea seemed to be the best solution in spite of its controversy. The time was running out. If they wanted to save their population, they had to take out the parasites immediately. Spacecrafts build. Parasites isolated. These E.T beings began to dispose their major competitor into outer space, letting them travel anywhere the gravity took them.  NASA detected one of these spacecrafts in the middle of its journey to Earth. No contacts the made went answered. No comprehensible data could be collected. The ship stayed in orbit like the second moon for nearly a month before NASA bombarded it with missiles, splitting it into smaller pieces that landed all over the continent of America. Hunting parties sent to look for the remnants never found the traces of the parasites, and thus the world thought that the foreign object was completely harmless. Maybe it was just a part of old spacecraft that came back to Earth.The parasites contained within the ship were very much like virus. Without food from their hosts, the parasites had gone dormant, waiting for the time when their senses had sniffed another source of food. After more than half a millennium of sleep, they were awoken by giant cauldron of cereal in the form of planet Earth. They ate soil, drank saltwater, munched on stones. They replicated deep underground. Whatever came out of their bodies was not at all poisonous, but useless. The soil dried and dead. Saltwater turned blood red and dead. Stones crushed and dead.When they first emerged on land and spotted humans, they made no effort to disturb them. Humans couldn’t be eaten, so they left them be. But humans were scared and tired of losing properties. They killed them. Without a second thought.Later it was known that these creatures had a means of communication planted in each other’s central nervous system. When the first humans attacked, the parasites sent a signal, a message, that they got an enemy. Nearby friendlies who copied the signal then relayed to another one, on and on until it reached the entire community. That way they could collectively strengthen themselves and prepare for another attack. They evolved, like worms grew stronger by each dosage of anthelmintic.Slowly, humanity was pressured to strengthen themselves as well. War erupted. The damage and casualties were surpassing any historical records of war before. To deal with this, the world created Fortress, a universal military organization specially formed to take care of these creatures. Regional main bases built on critical points, called Nerve Center, and refugees fled from attacks were taken care. In the middle of the chaos, a nickname was given to the invaders of Earth. They called them Wreckers.  Note: very loosely based on the award-winning novel by Hiroshi Sakurazaka, All You Need is Kill, and BTS super-duper teaser images for Red Bullet.
