My name is Arthur and I am a down-and-out lord guarding a dilapidated fortress. His soldiers are about to die and the castle is about to fall. At this critical moment, I suddenly hear the sound of the system. It detects that the host is about to die. Should I activate the call from another world? I do it without hesitation. Then a group of players from another world all come into my field of vision. They are also a group of funny and weird players. In an instant, a lot of information floods into my mind. It turns out that the system is like this. This world is my real world, but for this group of players, it corresponds to the game world in their world.
