Foo, a bright young man that happens to be a computer genius, who excels in life by taking shortcuts when possible. If life was a game, he would definitely pick the easiest mode. Exams in school? Just read all the books once, and make sure you don’t forget the contents. Looking for a job? Make sure everyone around the boss knows just how perfect you are for the job. Having others bragging about your excellence is more trustworthy and gives plausible deniability. Quiz time? Let me just start my special search engine's voice recognition. Competing in soccer? Aw, how unfortunate, the opposing team 'somehow' got their clothes filled with itch-inducing powder, leading to a walkover. Playing a FPS game? Well, lets just have my own mouse driver software get some headshots while I watch a movie. It’s perfectly legit, as it just speeds up the response time so that it clicks before I even get to the computer. Gambling sites and online casinos? Data-mining, number-crunching and image recognition! By utilizing computer knowledge, solving problems is easy! Some might get jealous, but hey! Just be like me, and use your brains for once! However, in the modern era, the gangsters and other shady businesses are moving their turfs towards the internet and gaming circles. What happens when they realize that Foo was a threat to their profits? Well, no suspense here, they killed him. That’s the end of story... if you are to believe the god that greets him after his death. However, can this story get a fresh new start when Foo somehow ends up in a game-like medieval fantasy world? Or will the lack of modern tools, like his beloved computers or other modern conveniences, cut his story short yet again? ------------------------------ Also, thanks to SageDrunkKitty and Remteldanmarkius for proofreading the synopsis! Any errors still there are their fault! The fact that I might not have listened on them does not automatically make it my fault, okay?
