How Can I Become a God Just by Playing a Game?

Steam, old gods, relics, firearms, artillery, airships, witches, churches... Levi traveled through time and found that a game console appeared in his mind, which allowed him to enter the game world and bring out the abilities and items obtained in the game. So, in reality, Levi worked as a civilian in the law enforcement team, drinking tea, reading newspapers, and playing games every day. In the game, Levi kills everyone. In "The Witcher", he kills monsters with a silver sword and evil people with a steel sword. In "Assassin", he flies over walls and stealthily assassinates. Everything is empty and everything is allowed. In "Riding and Cutting", he roams the battlefield, becomes invincible, builds an empire, and achieves hegemony... While playing, Levi suddenly found that he had become a god.
