I accidently declared war on earth

Ethan before a Dungeon outbreak that started a doomsday in his world was a massive fan of God like games including Universe Sandbox, World box, Deity sim etc. when the outbreak happened everyone had gained a system except his was broken unfunctional. in the new age he had to resort to being a porter barely scraping by and he had to move houses into the most dangerous parts of the city which he was killed by being near a massive shootout between illegal dungeon mob trading which sells dungeon animals or anything without license its a dangerous career and many destructions and casualties happen because of it but that's not the reason why people hated it so much, Thugs would usually randomly open fire at one another with enhanced weapons used for dungeons which would lead to craters forming big as a car which blew houses up like fire to a paper before Ethan died his system had been repaired and he gained a new chance at life
