Signing in Through Time Travel, I Became a Sword Fairy

I am the best sword in the world. I can kill immortals from above and demons from below. I can catch the wind and shadows. I can move mountains and overturn seas. A sword broke through the sky, shocking the world. Things in the world are impermanent, and the only thing that remains unchanged is the heart of the sword. I am willing to experience all the sufferings in the world in order to achieve the highest state. I am the enemy of all realms. I'm sorry, please treat me as an alien. If I am not shocked at this moment, I will go back and forth in this world.
