Fantasy: Let Me Be Invincible in All Realms with One Sword

One sword through the ages, the lord of all realms! The catastrophe of heaven and earth came, and countless powerful people flocked to this star field. Some of them were fighting, some were running for their lives, and some... Were killed! The sky was stained with blood, corpses were everywhere, broken arms and limbs and broken weapons were everywhere. The entire sky turned scarlet, that was blood, which flowed out after the death of living beings. This novel and its characters are purely fictitious.
