Milky Way Scar

In the 21st century AD, human beings entered the cosmic era and developed rapidly into the universe. However, while humans were developing the universe, cosmic beings were also coveting the earth. Today's earth is a state where humans and cosmic beings coexist, but the seemingly peaceful life does hide dangers. In order to protect this new star that has just integrated into the universe, the Galactic Union of Interstellar The Lawkeepers (G. U. I. L. D) dispatched Yin Xinglie, an ace law enforcer who has been active on various planets, to the earth. This is where the story begins.
