In this world, there are three parallel worlds. These three worlds do not interfere with each other. One day, the barrier between the two worlds is torn open, and countless black energy and monsters pour out from it. All countries are unable to resist, and only five big countries can barely resist and survive.
So there are people alive who don't know... If they can survive tomorrow.
However, in our world, there are also mysteries and monsters, and they have also awakened. In this world, the only ones who can resist the invasion of monsters are the gods and a small number of people recognized by the gods. As time goes by, the gap becomes wider and wider, the monsters become more numerous and stronger, and humans are on the verge of being unable to resist.
Later, the country's top leaders and senior officials named the monster...
Senior leaders led those who were able to resist and formed an organization to protect the people.
After nearly a hundred years, not many people know about this organization. They have been forgotten. The protector who walks at night has been forgotten by the people she protects. But forget it, it is better to let them know what happened a hundred years ago.
