In the future in 2020:
It was a dark peaceful night when a meteorite fell into the earth carrying an unknown carbon compound. When the asteroid reached the Earth's atmosphere, a series of explosion occurs and the carbon compound fuse with every element or compound it had contact with. Unstable fusion and fission occured, gasses that pass through the human body sometimes fuse creating an abomination or it could fission, which cause the body to explode or deconstruct. Some animals deconstruct creating a vile of liquid, when taken in cause transmutation or transformation into new creature or prehistoric creature. Human and animals become cannibals. Evolution goes reverse and earn new characteristics. Animal instincts went wild, panic surge throughout the whole world. The END of the World.
"This is so stupid!"Rei cursed at his luck while running, especially when he was just eating sandwiches at home and suddenly got barged in by a wild hungry rat. Luckily, he spotted a kitchen knife near a table. He rushed to the knife and held it by his dominant while his other hand is held at his chest to ready himself from the attack of the rat. The rat bit his hand that was held at his chest, then Rei struck the rat with the knife at the neck with all his strength thus killing it. It was no surprise to Rei that the big rat is mutated, he already knew it from the news on the internet but he didn't believe it a couple of moments ago. Rei then took the rat and began to cut it's meat, he believed that to be prepared is half-way to victory. He also took out some necessary tools for survival such as thick clothes, boots, shoes, water bottles, sharp edged metals, preservatives and additives. He also took a phone, to ensure he will receive updates and a solar-charged battery and flashlight. He proceeded to cook the rat meat and fed it to his dog, he is experimenting about the effects of the meat of mutated animals to the person or animal eating it. What if the mutated meat itself can improve body constitution is what he have in mind.
