Cosmic Sword Array

The Milky Way has experienced 20,000 years, and has inherited the sword formation. When the earth is bored, it hunts down some goblins that have sneaked into the city, or enslaves these goblins with diamond rings; in the Milky Way, it casually smashes some planets and admires the meteorite rain all over the sky; it is invincible in one side of time and space, seeking defeat alone... Ps: Alternative infinite, dark style, decisive killing.
