I would be able to meet my family, aka- my dog and my friends. and just so you know that I am not immortal anymore. it was just so that I could get habituated to this illusioary world. and the voices I heard were of the system's, they were trying to mess with me. a few days later a few mobs started appearing where I lived. a super luxury penthouse. I could take care of them easily because where I come from we have to serve in the military for a minimum of 24 months. so I had been taught how to fight and defend myself and also how to use weapons, and had also been taught martial arts. the starting few days only goblins and slimes were appearing but a month later the difficulty level started increasing and mobs like wolfs and orcs started spawning. but I could handle it by myself. and a few days later a message popped up...
