Zombies: Too Many Cheats

Wake up and travel to the zombie world. Not only was I teleported to a cemetery at the beginning, but I was also haunted by an old ghost. I finally got rid of the old ghost, but I didn't expect that the system told me to travel to the zombie world. There is no other way but to complete the tasks issued by the system and intervene in the original plot to obtain rewards and improve your strength. I didn't expect that the system informed me that I could return to the original world. I didn't expect that the original world was not as simple as imagined.
