The Merc System.

Due to the overbearing waste of mankind, earth got knocked off balance by the impurities. Which resulted to violent weather conditions, and disturbing mutations in both man and animal. The government quickly built-in interconnected underground strongholds in various states and countries, for the survivors who were immune to the mutation to take refuge in. But something strange was later on discovered... Some of the survivors began displaying potentials of magical abilities, and after a series of research by the government, they decided to launch a life-like game which would increase the chances of an individual gaining a magical ability. - Jayden Logan had gained a system instead of a magical ability before the launch of 'Hope online', but when he discovered he could only summon a slingshot rifle with throwing knives, he became too embarrassed to tell anyone, and gave people the impression that he was powerless. He was hoping on 'Hope online' to magnify his chances of gaining a magical ability... but things just never go as planned in this accursed world.
