My Weapon Is a Cat

My name is Luo Ansi. I was originally an ordinary high school student, but strange things have happened frequently recently. I always dream about sudden ghosts, but when I wake up from the dream, I find nothing I didn't take these things to heart at first, but one day, the system went online! These are actually true! The system also asked me to challenge the dungeon and hunt monsters I really can't imagine it, but the system is still very humane and allows me to choose weapons. It would be better if it is not in my home. I didn't even think there was anything to take, but Xiao Hei jumped into my hand, and the weapon selection countdown just ended. I'm completely confused My weapon is a black cat! Well, I choose to accept the reality and take Xiao Hei with me to go through the level. I hope I can succeed.
